When you _ , you'd better not wear a pair of jeans. | A | Read the passage and answer the question. | Passage:
150 Years of Cool
Look in the bedrooms of young people around the world. You will probably find a pair of blue jeans in each room. Jeans are very popular all over the world.
Jeans give you the feeling of comfort, youth and energy. They have long been liked by every person.
Levi Strauss is an American company. It first made blue jeans. The company was founded in 1853 by 24-year-old Levi Strauss. Twenty years later, he made the first blue jeans in the world. The jeans were used as working trousers for the cowboys of the American West. During the Second World War, American soldiers brought blue jeans to Europe and Asia. People there began to wear jeans. Little by little, they become cool.
People from different countries like different styles of jeans. Americans like to wear simple and single-colored jeans, but many Chinese like to wear jeans with lots of different colors.
Jeans now can be seen everywhere: However, in many places, it's not always good to wear jeans. No matter how good they may look, or what color they are, it's often not right to wear jeans in formal places. But, when you are out, relaxing and having fun, jeans are the best choice.

If people want to know the treehouse with Turkish carpets, they should visit _ . | D | Read the passage and answer the question. | Passage:
If you are tired of common hotel rooms, maybe it's time to climb into a tree. A new generation of tree houses are appearing across the world, and designer Roderick Romero says he knows why and he said "They're magical. I've never seen someone climb into a tree house and not smile."
Edisto River Canadys, S. C.
Before you can stay in one of the wilderness tree houses, you first have to canoe down the Edisto River. The paddle-in homes offer a cooking gear and comfortable sleeping bed. "It's a really good place to get back to nature," Romero says. The lofts have gas stoves and are lit by lanterns. The website: caneosc.com
Treehotel
Romero was astonished when he first saw the buildings at this hotel 40 miles south of the Arctic Circle in northern Sweden. "It blew my mind. I couldn't believe what I was seeing." he says. The hotel rooms draws heavily on spare Scandinavian design. "Architecturally this is one of the coolest ideas for a tree house.'' The website: treehotel.se
Hideaway Cafe
While most treehouses are found in the woods, this coffee shop and inn turns the idea on its head with a location in downtown Tokyo. The building itself stands on stilts with a tree growing through the center of it. The cafe was the first treehouse designed by Kobayashi Takashi, who has since created more than 120 homes. "He's one of my heroes." Romero says, "In the treehouse community, he's who we talk about the most." The website: treehouse.jp/ hideaway/.
Tongabezi
One of the world's most stylish treehouses perches in a tree alongside the Zambezi River near Victoria Falls. The large pine deck holds a bed and Turkish carpets. Guests can go on safati, or simply stay in their perch and watch for hippos playing in the river. The website: below.tongabezi.com.

How many reasons did the writer give to support his/her opinion? | D | Read the passage and answer the question. | Passage:
An American educational expert, Frederick M. Hess, says that a long summer vacation doesn't make sense in today's world.
This summer, 50 million kids will spend much time talking online, watching TV, playing video games and asking older brothers or sisters to take them to the supermarket. They will also be putting their academic futures at risk.
During much of the 20th century, many Americans worked in factories that did not need a college degree but still offered a high salary. Also, in the 19th century, there was no air condition. And poor hygiene meant that crowded schools had health risks.
Things have changed. For today's students, academic skills are key to future success. Many countries don't give kids an American-style summer vacation. They offer no more than seven consecutive weeks of vacation. Most American school districts offer up to 13 weeks. To compete in global marketplace, Americans must be prepared to go up against international competitors.
Summer vacation also causes challenges for today's families. In the 1960s, more than 60% of families had a stay-at-home mum. Now, two-thirds of American children live families where every adult works. For these families, summer vacation can be more burden than break. Someone must watch the kids.
But the biggest problem may be how summer vacation hurts academic achievement. Scientist have found that disadvantaged students lose important ground in the summertime.
A school year can allow time-limited teachers to conduct richer and more imaginative lessons. Schools would have more time for sports, languages, music and the arts.

Lilith originally had five dozen water bottles that she needed to sell at $2 each to get exactly enough money to buy her friend a birthday gift. However, at the store, Lilith realized she could not sell at $2 because the regular price was $1.85 per water bottle in her town, and she had to reduce her price to $1.85 as well to sell her water bottles. Calculate the total amount of money Lilith will have to find to buy her friend the birthday gift after selling her water bottles at the reduced cost. | Lilith had 5 dozen water bottles, and since a dozen has 12 water bottles, the total number of water bottles she had was 12 bottles/dozen * 5 dozen = <<12*5=60>>60 bottles

In the European Union which foreign language is studied by the fewest people? | C | Read the passage and answer the question. | Passage:
English has gained status as a world language. About 1/3 of the world's population has English as its mother tongue. 75% of the world's mail is in English.
English is the official language or is widely used in the United Kingdom, Ireland, Australia, New Zealand, India, United Arab Ernirates, Canada, the United States, Panama, Surinam, South Africa, Nigeria, and Kenya. English is the language that is most often studied as a foreign language in the European Union (by 89% of schoolchildren), followed by French (32%), German (l8%), and Spanish (8%). It is also the most studied in China, Japan, and South Korea. Books, magazines, and newspapers are written in English in many countries around the world. English is also the widest used language in science. In 1997, the Science Citation Index reported that 95% of its articles were written in English, but only half of their authors came from English-speaking countries.
Why has English become a world language? The British colonized (......) large parts of the world, spreading their language to new areas. The United Kingdom and the United States are both important nations in the world. When doing business with these nations, knowing English is an advantage. As non-English-speaking countries realized that, industry and business hired people who spoke English, or required their workers to attend language courses. English is the international language of technology.
With English being so widespread, it can make those who come from English-speaking countries already feel that they don't need to learn a foreign language. This is not good because one learns to understand a culture better if one knows the language, and one may also enjoy reading original books.

According to the author, we should _ . | B | Read the passage and answer the question. | Passage:
We have a strange and strong belief in the idea of perfection. Driven by our culture, we struggle for an unattainable ideal: If I have the perfect parents, perfect grades, perfect..., then I would be happy. We seek what we can't have without remembering that we don't actually need to be perfect. Imperfection allows us to be human.
Parents, teachers and other high-achieving peers will have us believe that we must be perfect if we wish to remain competitive. However, what job or school requires you to develop a cure for some form of cancer by the age of 18? Although these grades would be admirable achievements, are they worth losing sleep over? We feel like we need the perfect grades to get into the perfect college that will provide us with the perfect education necessary to obtain the perfect job. Making use of our thirst for perfection, the whole college and career industries have emerged claiming to help us reach our goals.
Truth is, you only need to be good enough to get into the conversation. It is what you do afterwards that sets you apart. Focus more on your passions. Don't worry about anything secondary to your passions. You don't become an expert at anything if you spent your time trying to succeed in everything you do. You only become an expert when you devote your time to that one project that truly brings you joy.
As members of this society, we have a responsibility to be excellent in what we do, not perfect. Although perfection can be a goal, it should not be the only goal. We only have 24 hours in a day and seven days in a week. Thus, we need to plan what we want to do and cut out the activities we cannot do.
With everything, though, make sure you're doing enough. Pursuing your passions is not enough of a reason to completely give up on everything else. Try as hard as you can and let your future worry about itself. Worry about your task at hand and you will be successful in achieving your dreams. Most of all, remember that you're going to be okay.

Warming up adequately and stretching before playing sports may reduce the risk of a sprain. Ligament injuries can take a long time to heal. Rest, ice, compression, and elevation of the sprained area may help the healing process. | null | null | null |
People who think happiness lies in the town would feel that _ if they had to live outside London. | A | Read the passage and answer the question. | Passage:
Many people who work in London prefer to live outside it, and to go in to their offices or schools every day by train, car or bus, even though this means they have to get up early in the morning and reach home late in the evening.
One advantage of living outside London is that houses are cheaper. Even a small flat in London without a garden costs quite a lot to rent. With the same money, one can get a little house in the country with a garden of one's own.
Then, in the country one can rest from the noise and hurry of the town. Even though one has to get up earlier and spend more time in trains or buses, one can sleep better at night and during weekends and on summer evenings, one can enjoy the fresh, clean air of the country. If one likes gardens, one can spend one's free time digging, planting, watering and doing other jobs which are needed in a garden. Then, when the flowers and vegetables come up, one has the reward of one who has shared the secret of Nature.
Some people, however, take no interest in country things: for them, happiness lies in the town, with its cinemas and theatres, beautiful shops and busy streets, dance-halls and restaurants. Such people would feel that their life was not worth living if they had to live it outside London. An occasional walk in one of the parks and a fortnight's (two weeks) visit to the sea every summer is all the country they want: the rest they are quite prepared to leave to those who are glad to get away from London every night.

When Tyler was talking in class, the teacher advised him to _ . | A | Read the passage and answer the question. | Passage:
Tyler was a troublesome student. He sat in the back row. Every time I called him to answer questions, he'd reply with a flip answer. If he got it wrong, he would get very angry.
Usually kids could sit quietly in class. However, Tyler was just loud. One day, Tyler was talking while I was teaching. I said to him, "Tyler, why not join in our discussion instead of having one of your own?" He got up from his chair, pushed it over, and shouted something I can't remember. I sent him to the office and he received a week's out-of-school punishment.
The week was a wonderful time for me, but when it came to an end, I began to feel worried. So I came up with a plan. On the day of his return, I told him I wanted to start over with him. If he felt like he was going to lose control in class, he could step outside the door for a moment.
From then on, Tyler was a changed student in my classroom. In fact he was a smart child and he even stopped a fight between two students one day. And he never used the privilege to leave the class for a moment. I believe that just letting him decide for himself made all the difference.
When the year was over, he wrote me a thank-you note about how good the year had been for him. I still have it today and find it very moving to reread when I get stressed about teaching.

Which of the following is NOT true of loud music? | C | Read the passage and answer the question. | Passage:
Listening to music while you drive can improve your speed and ability to get away from accidents, according to Australian psychologists. But turning your car radio up to full volume could probably make you end up in an accident. The performance of difficult tasks can be influenced if people are subjected to loud noise. The experience of pulling up at traffic lights alongside cars with loud music made some psychologists in the University of Sydney look into whether loud music has something to do with driving.
The psychologists invited 60 men and women aged between 20 and 28 as subjects and tested them on almost the same driving tasks under three noise conditions: silence, rock music played at a gentle 55 decibels , and the same music at 85 decibels.
For 10 minutes the subjects sat in front of a screen operating a simple machine like a car. They had to track a moving disk on screen, respond to traffic signals changing color1, and brake in response to arrows that appeared without warning.
On the tracking task, there was no difference in performance under the three noise conditions. But under both the loud and quiet music conditions, the performers "braked" at a red light about 50 milliseconds sooner than they did when there was no rock music at all. That could mean a reduction in braking distance of a couple of meters actually, the difference between life and death for a pedestrian.
When it came to the arrows that appeared across the visual field, the psychologists found that when the music was quiet, people responded faster to objects in their central field of sight by about 50 milliseconds. For the people listening at 85 decibels, response times were dropped by a further 50 milliseconds -- a whole tenth of second faster than those "driving" with no music.
"But there's a trade-off," the psychologists told the European Congress of Psychology. "They lose the ability to look around the whole situation effectively." In responding to objects that suddenly appeared, people subjected to 85-decibel rock music were around 100 milliseconds slower than both the other groups. Since some accidents -- such as children running into the road -- take place without any notice, drivers listening to loud music must be less safe as a result.
Question:
Which of the following is NOT true of loud music?

A. It helped the performers to brake sooner at red lights.

What is used to report the results of scientific measurements? | null | Answer the following science question clearly and accurately. | What is used to report the results of scientific measurements? | si units | science | null | null | null | los units | bi units | latin units | si units | The number in the measurement can be represented in different ways, including decimal form and scientific notation. (Scientific notation is also known as exponential notation; a review of this topic can be found in Appendix B. ) For example, the maximum takeoff weight of a Boeing 777-200ER airliner is 298,000 kilograms, which can also be written as 2.98 × 105 kg. The mass of the average mosquito is about 0.0000025 kilograms, which can be written as 2.5 × 10−6 kg. Units, such as liters, pounds, and centimeters, are standards of comparison for measurements. When we buy a 2-liter bottle of a soft drink, we expect that the volume of the drink was measured, so it is two times larger than the volume that everyone agrees to be 1 liter. The meat used to prepare a 0.25-pound hamburger is measured so it weighs onefourth as much as 1 pound. Without units, a number can be meaningless, confusing, or possibly life threatening. Suppose a doctor prescribes phenobarbital to control a patient’s seizures and states a dosage of “100” without specifying units. Not only will this be confusing to the medical professional giving the dose, but the consequences can be dire: 100 mg given three times per day can be effective as an anticonvulsant, but a single dose of 100 g is more than 10 times the lethal amount. We usually report the results of scientific measurements in SI units, an updated version of the metric system, using the units listed in Table 1.2. Other units can be derived from these base units. The standards for these units are fixed by international agreement, and they are called the International System of Units or SI Units (from the French, Le Système International d’Unités). SI units have been used by the United States National Institute of Standards and Technology (NIST) since 1964. Base Units of the SI System Property Measured. | null | null | null |

"I wish our bank would be robbed," said George Pickens, the bank clerk, to himself. "If one day a robber holds up me. And if I have to give him a certain amount of money. What is to prevent me keeping all the money left and claiming that the robber had taken it?" Just then a tall and strong man walked in, wearing a mask. "This is a holdup!" the man said. Roughly, taking a gun from his pocket and stepping over to George's cage. "All right, hand it over!"
"Yes, sir," said George. "Would you like it in ten-or twenty-dollar bills?"
"Just hand it over!" said the robber. George took all the bills from the top section close to six thousand dollars. He passed them through the window. The robber snatched them, stuffed them into his pocket, and turned to leave. Then, while everyone was watching the robber, George calmly lifted off the top section of the cashbox and slipped bills from the bottom section into his pockets. The door swung and the robber was gone. George fell down and fainted. When he came to he smiled up at the worried faces looking down at him. "I'm all right," he stated bravely.
"You might just as well go home, George." Mr. Bell, the chief accountant, said.
As soon as he was safely behind his bedroom door, George took the money from his pockets and counted it. Seven thousand dollars!
The next morning when George arrived at the bank, it was not open for business, but everyone was there, helping to check the bank's accounts. George was called into Mr. Burrows' office. The bank president seemed strangely cheerful. "George," he said, "I want you to meet Mr. Charles, who used to be president of our bank."
"Good morning, George," said the former president. "I was extremely sorry to hear you fainted yesterday. Are you all right now?"
"Yes, sir, just fine, thanks."
"I was sorry to give you a hard time yesterday, but with all the banks being robbed these days, I played my little game yesterday, just to keep everybody on his toes."
"I don't understand," said George. "What game?"
The old man laughed and quickly took out a mask. He placed it over his face and said, "All right. Hand it over!" Mr. Burrows laughed but George didn't.
"And the money?" George asked in a faint voice.
"Don't worry," Mr. Charles said. "I put it all back in your cashbox--- all six thousand. We're just finishing up the check-up now." Behind them, the door opened and Mr. Bell put his head into the room. "Mr. Burrows," he said gravely, "may I see you a moment?"

Why has smog become a common concern? _ | D | Read the passage and answer the question. | Passage:
Since the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog is especially a common concern. As a popular online post said, air may be the only thing that is equal for everyone, despite your income or profession. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. "After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life," he said.
China needs to develop its economy and invest in hightech. Every Chinese has a dream to make China stronger. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can move to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. The great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's determination to address the environment issue.

Frank Furedi believes that _ . | D | Read the passage and answer the question. | Passage:
All schoolchildren should have "happiness" lessons up to the age of 18 to combat growing levels of depression, according to a senior government adviser.
"Pupils should study subjects such as how to manage feelings, attitudes to work and money, channeling negative emotions and even how to take a critical view of the media," said Lord Richard Layard, a Labor peer and professor of economics at the London School of Economics.
The proposal comes only days after the Government said that lessons in manners--including respect for the elderly and how to say "please" and "thank you"--should be taught in secondary schools to combat bad behavior.
Lord Layard, the director of the wellbeing program at the LSE's Center for Economic Performance, said: "Learning hard things takes an enormous amount of practice. To play the violin well takes 10,000 hours of practice. How can we expect people to learn to be happy without large amounts of practice and repetition?"
It is believed that at least two percent of British children under 12 now struggle with significant depression. Among teenagers, the figure rises to five percent. A UNICEF study involving 21 developed countries showed that British children were the least satisfied with their lives, while the World Health Organization predicts that childhood psychiatric disorders will rise by 50 percent by 2020.
In a speech at Cambridge University, Lord Layard said the Government's lessons in manners did not go far enough. "We need a commitment to producing a major specialism in this area, with a serious teacher training program," he said.
However, happiness lessons have been criticized by academics. Frank Furedi, a sociology professor at Kent University and author of Therapy Culture, said: "In pushing emotional literacy, what some teachers are really doing is abandoning teaching. They are giving up and talking about emotions instead, so that children value all this non-discipline-led activity more than maths, English or science.

Choices:

C. formal teaching can go side by side with happiness lessons
D. formal teaching should not give way to happiness lessons | Answer: D | reading | null | null | null | null | null | null | null | null | high16999.txt | All schoolchildren should have "happiness" lessons up to the age of 18 to combat growing levels of depression, according to a senior government adviser.
"Pupils should study subjects such as how to manage feelings, attitudes to work and money, channeling negative emotions and even how to take a critical view of the media," said Lord Richard Layard, a Labor peer and professor of economics at the London School of Economics.
The proposal comes only days after the Government said that lessons in manners--including respect for the elderly and how to say "please" and "thank you"--should be taught in secondary schools to combat bad behavior.
Lord Layard, the director of the wellbeing program at the LSE's Center for Economic Performance, said: "Learning hard things takes an enormous amount of practice. To play the violin well takes 10,000 hours of practice. How can we expect people to learn to be happy without large amounts of practice and repetition?"
It is believed that at least two percent of British children under 12 now struggle with significant depression. Among teenagers, the figure rises to five percent. A UNICEF study involving 21 developed countries showed that British children were the least satisfied with their lives, while the World Health Organization predicts that childhood psychiatric disorders will rise by 50 percent by 2020.
In a speech at Cambridge University, Lord Layard said the Government's lessons in manners did not go far enough. "We need a commitment to producing a major specialism in this area, with a serious teacher training program," he said.
However, happiness lessons have been criticized by academics. Frank Furedi, a sociology professor at Kent University and author of Therapy Culture, said: "In pushing emotional literacy, what some teachers are really doing is abandoning teaching. They are giving up and talking about emotions instead, so that children value all this non-discipline-led activity more than maths, English or science. What is amazing about this is that time and time again, research says that it does not work." | [

At what age do children in America spend about five and a half hours on the media a day? | B | Read the passage and answer the question. | Passage:
Zach Linsky, 11, watches TV for 3 and a half hours a day and plays video games every other day. Zach, a sixth grader in Washington, D. C., is an American. But unlike many kids, he doesn't have a TV, VCR, or computer in his bedroom. He only has a boom box .
The survey of 3,155 kids, aged 2 to 18, shows that they spend 5 hours and 29 minutes on average a day using some types of media outside of school, including 2 hours and 46 minutes watching TV, 21 minutes on the computer, 20 minutes playing video games, and 8 minutes on the Internet. The good news: The total includes 44 minutes spent reading.
The survey also shows that those aged 2 to 7 spend 3 hours and 9 minutes watching TV every day and shows that 32 percent in that age group have TV sets in their rooms. Among those aged 8 to 18, 21 percent have computers in their rooms, 65 percent have TV sets, and 61 percent say their parents don't stop them from watching TV. Nearly 1 in 4 say they watch more than 5 hours a day.
"Kids are living much more lonely lives than ever before," says Kay S. Hytnowitz. "They just disappear into their rooms and spend all of their time with these media."

According to the passage, which of the following is true? | D | Read the passage and answer the question. | Passage:
The small number of newborn babies, which has been caused by high prices and the changing social situation of women, is one of the most serious problems in Asia. When people talk about it, you can hear a word invented in Japan. which means Double Income Kids .
In many major Asian cities like Seoul, Singapore, and Tokyo, the cost of a ****** is extremely high. A young couple who want to buy their own house may have to pay about $3000,000 (though prices have fallen). For a flat with one bedrooms, one dining-room, a kitchen, and a bathroom, the couple will pay about $900 a month. What's more, if they want to have a child, the child's education is very expensive. For example, most kindergarten charges are at least $5.000 a year. In such a situation, it's difficult to afford children.
The number of married women who want to continue working because they enjoy their jobs. However, if they want to have children, they immediately have serious problems. Though most companies allow women to leave their jobs for a short time to have a baby, they expect women with babies to give up their jobs. In short, if they want to bring up children properly, both parents have to work, but it is hard for mothers to work. Indeed, women who want to contimue working have to choose between having children or keeping their jobs.
In a word, Asian governments must take steps to improve the present situation as soon as possible.

The author's purpose of writing this passage is _ . | C | Read the passage and answer the question. | Passage:
Anyone driving the twists of Highway 1 between San Francisco and Los Angeles recently may have glimpsed a Toyota Prius car with a curious-looking thing on the roof. Harder to notice was that the person at the wheel was not actually driving. The car is a project of Google, which has been working in secret but in plain view( anyhow, no one can keep such a thing from the public) on vehicles that can drive themselves, using artificial-intelligence software that can sense anything near the car and imitate the decisions made by a human driver.
With someone behind the wheel to take control if something goes wrong and a technician in the passenger seat to monitor the navigation system , seven test cars have driven 1,000 miles without human intervention and more than 140,000 miles with only occasional human control. One even drove itself down Lombard Street in San Francisco, one of the steepest and curviest streets in the nation. The only accident, engineers said, was that one Google car was rear-ended when it stopped at a traffic light.
Autonomous cars are years from mass production, but technologists who have long dreamed of them believe that they can transform society as profoundly as the Internet has.
Robot drivers react faster than humans, have 360-degree perception and do not get distracted or sleepy, the engineers argue. They speak in terms of lives that could be saved and injuries that could be avoided--- more than 37,000 people died in car accidents in the United States in 2008. The engineers say the technology could double the capacity of roads by allowing cars to drive more safely while closer together. Because the robot cars would eventually be less likely to crash, they could be built lighter, reducing fuel consumption. But of course, to be truly safer, the cars must be far more reliable than, say, today's personal computers, which crash on occasion and are frequently infected.
The Google research program using artificial intelligence to revolutionize the automobile is proof that the company's ambitions reach beyond the search engine business. The program is also a departure from the mainstream of innovation in Silicon Valley, which has turned toward social networks and Hollywood-style digital media. However, the Google researchers said the company did not yet have a clear plan to create a business from the experiments.

According to the author, what causes our current and future global problems? | C | Read the passage and answer the question. | Passage:
It is true that world population is growing, but this is not the cause of our current and future global problems. Believing this will cause us to ignore the real problem and risk long-term damage to our planet.
Let me start by explaining why overpopulation is a _ . For one thing, the UN Population Division regularly predicts population growth but provides a low variant , medium variant, and high variant to factor in various possibilities. In the 2010 revision, their high variant suggests that the world population will be almost 16 billion in 2100, but the low variant predicts it will peak at 8 billion and decrease to just over 6 billion by 2100. In most cases, it is the low variant that has come true in the past, suggesting the same will be true of their future population predictions. In addition to this, the size of families is actually decreasing.
For another, if the Earth is overpopulated, there needs to be insufficient food, water, and space for humans to live. However, Indian economist Raj Krishna estimates that India alone is able to increase crop produce to the point of providing the entire world's food supply. The World Food Programme confirms that there is sufficient food grown to feed the world and there is the same amount of fresh water on the planet now as there was 10,000 years ago. So how is it possible that the number of people in the world is affecting our planet?
Therefore, it is not an increase in population but an increase in consumption that is a severe threat. Materialism and overconsumption are facts of life for everybody in the western world, as possessions reflect a person's status in society and people strive to obtain happiness through owning the latest fashionable goods. Not only that, but waste is a common occurrence which has a huge effect on our resources. It is a sad truth that 80% of the world's resources are currently used by just 20% of the world's population.
Our overconsumption must be addressed now to make our lives more sustainable and avoid continuing the terrible damage to the environment we are causing. The key is education. If we do not work towards this but instead focus on the wrong issue, we may find ourselves living on a planet that can no longer sustain human life.

A recent survey made by BUPA, an international healthcare provider, shows that 54 percent of Chinese people aged between 45 and 54 consider themselves old, while 28 percent say that the thought of getting old upsets them. 25 percent are afraid of getting old, and a third worry about life in old age.
BUPA made the survey among 12,262 people from 12 countries over 2 months, starting in June 2010. The survey shows that 72 percent of international participants aged over 65 don't feel old and that 67 percent still feel healthy. On the other hand, 65 percent of Chinese feel old even before reaching 60. About one third of those surveyed in China said they have enough savings , and 46 percent are insured . Around 60 percent of the Chinese participants hope they will be taken care of by family members.
According to the survey, the French hold the most positive attitude towards getting old, with 32 percent of them considering age 80 and up old. 17 percent of Brazilians look forward to old age, compared with 3 percent globally. Indians are not bothered by old age, as 70 percent said that they don't feel that they will be affected by old age and 71 percent say they have already made preparations for this stage of life.

Can food be free, fresh and easily accessible? That's the bold question that the city of Seattle is hoping to answer with a new experimental farm not far from the city's downtown area that will have fruits and vegetables for anyone to harvest this fall.
On Beacon Hill, just south of central Seattle, landscape developers and a few affordable-food advocates are building an eatable food forest. Everything grown in the area will be eatable. And it'll be open around the clock to anyone who wants to come and pick some fresh blueberries or pears.
Organizers shared with National Geographic a list of the crop offerings. Many are expected: apples, berries and tomatoes. But others are pretty far-out. A large Asian community in the area suggested things like Asian pears and honeyberries. A European influence led to the planting of medlar trees.
The concept is modeled on permaculture, a design system and school of thought emphasizing the use of renewable nature resources and the enrichment of local ecosystems. Offering people free, fresh food is one motivation, but making the land useful and ecologically enriched is the larger goal.
That being said, some potential problems come to mind. What if all of one fruit is gone the first weekend when it's ripe? What if people pick things too early and spoil the potential for everyone?
Organizers aren't concerned about those questions. "We've had many discussions about what would happen if someone comes and picks all the blueberries," says Margarett Harrison, the landscape architect designing the project." But that's been considered as a good thing. We'll just plant more."
Anything related to agriculture and good food -- in large quantities -- takes time. Most of the trees won't be mature enough for a few more years. But a few decades could make the area impressively productive.
Idealistic? Perhaps. But it's the kind of idealism that anyone who likes to eat fresh things from time to time can get behind. And that's the type of motivation that organizers hope will keep going.

Why does Tsinghua University enter the list of the best-looking campuses in the world? | C | Read the passage and answer the question. | Passage:
Forbes asked a panel of architects and campus designers to nominate their picks for the best-looking campuses in the world. These are their top choices.
Kenyon College
Gambier, Ohio, US
Mike Evans, a principal at Norfolk, Va., design firm Hanbury Evans Wright Vlattas + Company, says to be beautiful a campus must have a "signature campus space as a carrier of the campus brand." At Kenyon College, that space is "Middle Path," a 10-foot-wide footpath that serves as the Gothic hilltop campus' central artery. More than just a trail, it's a village green for the tight-knit campus community. Sergei Lobanov-Rostovsky, who teaches 17th-century poetry at Kenyon, says the college, both isolated and pastoral, is "a small place to think big thoughts."
Oxford University
Oxford, England
Teaching within Oxford's stone walls dates as far back as the 11th century, and the school is considered a paradigm for all college campuses. With its labyrinth of quads, cloisters, and archways, it evokes elegance and tradition at every turn. "Its monastic roots and the spectacular quality of its buildings make it an architectural wonderland," says David Mayernik, associate professor at Notre Dame's School of Architecture.
Princeton University
Princeton, N.J., US
Princeton's style is pure Collegiate Gothic ; most of it executed in gray stone covered in, yes, ivy. As imposing as these old stone structures are, the campus keeps life on a "human scale" by preserving green spaces and walkability.Sinuous footpaths, archways, plazas - all are designed to inspire spontaneous discussion and learning.
Scripps College
Claremont, Calif., US
The total plan of this women's college, founded in the 1920's, has always called for artistic connection between buildings and landscape. Together, architect Gordon Kaufmann, in collaboration with landscape architect Edward Huntsman-Trout, created a distinctively Southern Californian blend of Mission Revival-inspired architecture and landscape, which is lovely, evocative and intact. An expert in deciduous trees, Trout planted rows of liquid amber trees to give the students "a sense of autumn" come fall. He also peppered the campus with tulip trees, sycamores, almond and orange trees, as well as rare shrubs.
Stanford University
Palo Alto, Calif., US
New additions like the Science and Engineering Quad manage to gracefully blend modern and technological elements with the timeless, elegant aesthetics of the campus' early California Mission Revival architecture. The campus also scores big points for its dramatic entrance via Palm Drive, its romantic Spanish red-tile roofs and myriad patches of green.
Tsinghua University
Beijing, China
Forbe's panel of architects says natural setting plays a big part in assessing a campus' beauty. In that regard, this campus is blessed: Founded in 1925, Tsinghua sits on the former site of the Qing Dynasty's royal gardens. Many of Beijing's most notable historical sites, like the Summer Palace, are close by. The campus is peppered with artificial ponds where stone benches and floating lotus blossoms inspire reflection.

If you want to become a fluent English speaker you should take some advice. There are four skills in learning English. They are reading, listening, speaking, and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills, you should first master the skills of reading and listening.
Read as much as you can. But your reading must be active. It means that you must think about the meaning of the sentence, the meaning of the unfamiliar words, etc. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you _ , but the fact that you see them for the first time and recognize them whenever you see them, for example, in other passages or books, is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it.
As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading, then you can catch up on your listening. Since you have lots of inputs in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice listening. For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or if you are good at listening you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes.
If you follow these pieces of advice, your speaking and writing will improve quickly, and you can be a fluent English speaker one day.

How do many English people spend their holidays according to the passage ? | A | Read the passage and answer the question. | Passage:
DIY, which means Do It Yourself, is quite popular in UK. Lots of stores and supermarkets sell DIY things. TV programs show people how to DIY.
English people like DIY. There is a saying in UK---"An Englishman's home is his castle". Huge numbers of people spend their holidays making their homes beautiful "castles". If there is anything that needs fixing around their houses, such as painting the walls or putting in a new shower, they will do the jobs themselves. They share DIY experiences with their friends. More and more people have discovered the joy of DIY. Sometimes people also DIY for saving money. With the economic downturn at present, many people can not afford to buy a bigger house. They are looking at how they can make their houses better without spending a lot of money. It is not surprising that DIY is so popular.
DIY can be difficult. There is a huge market for DIY furniture which people need to put together themselves with a few basic tools . However, people often find it not easy to build a piece of furniture because they can't understand the instructions. Sometimes the instructions are simple and clear, but the furniture itself is difficult to build. One thing is for sure, though most DIY projects are started with the best intentions (,), many of them may not get finished. DIY can also be dangerous. For example, anything electrical should be done by a professional worker. Unluckily, many people don't care about this warning and put themselves in danger. It is reported that in just one year over 230 000 people were hurt while doing DIY in UK, including 41 000 who fell off ladders .
Therefore, DIY can bring us fun and help us save money, but it is not always as easy as it is thought to be if _ . Maybe factories should make products that are easier and safer for us to DIY.

Some fish will be over-fished to the point that their species ceases to exist, which is also known as what? | null | Answer the following science question clearly and accurately. | Some fish will be over-fished to the point that their species ceases to exist, which is also known as what? | extinction | science | null | null | null | abundance | endangered | accumulation | extinction | will inevitably make it more difficult and costly to grow food. The world’s growing human population faces significant challenges in the increasing costs and other difficulties associated with producing food. Wild Food Sources In addition to growing crops and raising food animals, humans obtain food resources from wild populations, primarily wild fish populations. For about one billion people, aquatic resources provide the main source of animal protein. But since 1990, production from global fisheries has declined. Despite considerable effort, few fisheries on Earth are managed sustainability. Fishery extinctions rarely lead to complete extinction of the harvested species, but rather to a radical restructuring of the marine ecosystem in which a dominant species is so over-harvested that it becomes a minor player, ecologically. In addition to humans losing the food source, these alterations affect many other species in ways that are difficult or impossible to predict. The collapse of fisheries has dramatic and long-lasting effects on local human populations that work in the fishery. In addition, the loss of an inexpensive protein source to populations that cannot afford to replace it will increase the cost of living and limit societies in other ways. In general, the fish taken from fisheries have shifted to smaller species and the larger species are overfished. The ultimate outcome could clearly be the loss of aquatic systems as food sources. | null | null | null |
Which of the following is _ a reason for the heavy haze? | B | Read the passage and answer the question. | Passage:
BEIJING--Heavy haze still covered north and east China on Saturday, with
highways closed and flights delayed or canceled .
The smoggy weather affected the country's land from north to south, including Beijing, Hebei, Shandong, Jiangsu, Shanghai, Zhejiang, Hunan, Guangxi and Guangdong, with visibility less than 50 meters in some areas.
Cities like Shanghai and Nanjing have been enveloped in the grey sky for the past several days. Many walkers in the street had to wear masks. In the Lukou airport in Nanjing, Jiangsu Province, more than 60 inbound and outbound flights were canceled on Saturday because of the hazy, which also forced primary and middle schools and kindergartens to stop classes on Thursday and Friday in Nanjing.
The Ministry of Environmental Protection said earlier this week that there were several main reasons behind the widespread haze: unfavorable weather conditions making it difficult for pollutants to diffuse , motor vehicle exhaust , coal use for winter heating.
The Chinese government now plans to clean up the air by cutting coal use, closing some factories and promoting cleaner production.
"We must face up to the realities," said Yan Naiqiang, a professor of environmental science at Shanghai Jiao Tong University. "The treatment of smog will be a long battle."

CHICAGO (Reuters) - Smoking not only can wrinkle the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.
The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.
"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.
"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.
The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person's skin was.
When skin is exposed to sunlight, notably the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.
Several previous studies have found that cigarette smoking contributes to premature skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.
The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels beneath the skin to constrict , reducing blood supply to the skin.
Smoking can also damage the connective tissue that supports both the skin and the internal organs.

Human beings have benefited a lot from seafood because _ . | D | Read the passage and answer the question. | Passage:
Maps of the world's population show that the majority of people today live near water. We live along coastlines, around bays, up the course of rivers and streams and on islands. We also vacation at the beach and find comfort fishing on a lake. Nothing makes small children happier than the chance of playing in water.
More surprisingly, this human favor for water makes evolutionary sense. Sure, we need drinking water to live, but we have also benefited from what's swimming under the waves.
Neuroscientist Crawford of the University of North London has proposed that our ancient ancestors attached to the sea, and that their devotion paid off by allowing the human species to develop large and complex brains.
Crawford claims that when humans separated from apes and appeared in the forests of Africa, they stuck close to rivers and beaches and started catching fish, clams and crabs. That seafood was packed with omega-3 fatty acids, essential fatty acids that promote brain cell growth.
It's no coincidence, Crawford claims, that human brain growth began to increase rapidly once we left the woods and headed for the beach.
Scientists have also discovered that people who eat fish regularly are less likely to suffer from depression than those who eat less seafood. Biochemist Hibbelin of the National Institutes of Health has shown that across cultures there is a direct link between amount of fish eaten each week and rates of depression. More interestingly, Hibbelin and researcher Laura have found that fish is commonly used as a symbol of happiness and good health in various religions and cultures.
We know that fish and the sea are good for us, and so we seek them out. We vacation on the coast and see the waves come and go, feeling happiness has taken over our brain. When we move inland, or go home from vacation, we lose touch with our sea roots and feel unhappy.

We can infer from the text that _ . | A | Read the passage and answer the question. | Passage:
Poetry is an interesting form of writing. It is very free, has few _ and can be a great way to express feelings. Writing a poem is all about observing the world within you or around you.
To write a poem, first you should begin with an idea or inspiration. Inspiration may come at any time unexpectedly. It may be a specific person, place or thing that causes some sort of strong emotion. It may be more of an abstract idea or release of emotion.
After getting the idea, you can write down everything that comes to mind. Don't think much and let all feelings pour out. Remember everything can be thrown out later.
Then, you can think about its form and begin to organize thoughts. Poetry comes in many forms, from epic poetry that has a story to dramatic poetry intended to be performed. Try them all out. One will come naturally. Maybe different poems fit different forms. When you write a poem, think about bothmeter and rhythm carefully, which are equally important in poetry. Meter is the fixed pattern of the poem, while rhythm refers to the sound when it is spoken. It is also important to use a lot of descriptive words. Createimagery with words, trying to make them attractive to all the senses. Forauditory interest, try repeating of similar sounds in a sentence or phrase. All of this adds life and interest to a poem.
After you finish your work, don't be afraid to share your work with others. When others point out your weakness, accept and grow from it.

Why do most people feel hard to make their travel dream come true? | C | Read the passage and answer the question. | Passage:
To travel around the world is the dream of many adventurous people. But very few people can afford a global tour because hotels, food and airplane tickets are too expensive. Some people, however, have thought of some ways to realize their dreams.
Laura Cody and Tanbay Theune, a couple from Britain, decided to travel around the world. They have found a good way to pay for their trips. They look after pets for rich house owners. In exchange, they can stay in the houses for free. They have looked after horses, cows, cats, dogs and fish. In two years, the couple has been to Australia, Germany, Spain and Italy. They have stayed in big cities and small villages. The home owners are usually very generous and have given them food, wine and day trips.
Another person who tries to realize her travel dream is photographer Rhiannon Taylor. She travels around the world to visit, review and take photos of the best hotels. She shares the places she stays in and the food she eats on the Internet with tens of thousands of followers.
With these ways of making money, traveling around the world is no longer a dream. More and more young people are thinking creatively to make their dream come true.

We can infer from the article that the author is _ human settlements on Mars. | C | Read the passage and answer the question. | Passage:
A MILLION people on Mars within 100 years. This is the brave vision of Elon Musk, the founder of the space technology company SpaceX.
"We need to be laser-focused on becoming a multi-planet civilization. That's the next step," he said in a recent interview with Aeon magazine. Musk expects to see about 80,000 people living on Mars by 2040.
It's all about protecting the human race from extinction, according to Musk.
The Earth has always been a ticking time bomb. As the sun begins to die, it will grow bigger, becoming what is known as a Red Giant. In 500 million years, the sun will have become large enough to kill off any plant and animal life on Earth, according to US scientist Edward Guinan. In a billion years, the Earth will have become a hot planet with little or no water.
The brave dream of getting the human race to Mars is not only Musk's; others have made plans, too.
A Dutch entrepreneur set up the Mars One foundation in 2011, hoping to be the first project to put humans on Mars. It received over 200,000 applications to become part of the first group of astronauts to go there.
According to Mars One, "human settlement on Mars is possible with existing technologies."
Water, food, energy, and oxygen are needed for life anywhere. According to Mars One, water that was still in the Martian soil would be boiled and taken out.
By using a process called "electrolysis", astronauts could split water into hydrogen and oxygen for breathing. Astronauts on the International Space Station have already done similar things.
Food can also be grown in space. Certain plants such as lettuce and onions can be grown using LED light for different color spectrums and much less heat. NASA has been researching this to prepare for visiting Mars.
But how will people get there? The Mars One project plans to use SpaceX's Dragon capsule as part of its mission. But it is rumored that Musk already has a design in mind for a giant spaceship. He calls it the Mars Colonial Transporter.

With a RFID implanted, which of the following will Mr. Donelson be able to do? | C | Read the passage and answer the question. | Passage:
A small group of people around the world have started implanting microchips to link the body and the computer.
Mr. Donelson and three friends, who had driven 100 miles from their homes in Loockport, New York, to have the implants put in by Dr. Jesse Villemaire, whom they had persuaded to do the work, are part of a small group, about 30 people around the world, who have independently put in microchips into their bodies, according to Web-based reports.
At a shop William Donelson was having a four-millimeter-wide needle put into his left hand. "I'm set,"he said with a deep breath. He watched as the needle pierced the fleshy webbing between his thumb and a microchip was set under his skin. At last he would be able to do what he had long imagined: strengthen his body's powers through technology.
By putting the chip inside--a radio frequency identification device (RFID)--Mr. Donelson would have at his fingertips the same magic that makes safety gates open with a knock of a card, and bridge and tunnel traffic flow smoothly with an E-Zpass. With a wave of his hand he plans to connect with his computer, open doors and unlock his car.
Implanting the chip was relatively simple task but very meaningful to Mr. Doneselson, a 21-year-old computer networking student so interested in the link between technology and the body that he has data-input jacks inside his body. _ might lead to an imagined future when people can be connected directly into computers. His new chip is enclosed in a glass container no bigger than a piece of rice and has a small memory where he has stored the words "Technology".
Some doctors have done the piercing in people's homes, and others have implanted chips in their offices after patients signed forms showing the fact that long-term studies have not been done on their safety. Piercers treat the implants much like any other medical operation steps, instructing people to keep the site dry, and advising them that swelling and redness should last a week.

How long has the People's Action Party (PAP) ruled Singapore? | A | Read the passage and answer the question. | Passage:
Lee Kuan Yew, former prime minister of Singapore, died on Monday, March 23, 2015, at the age of 91, according to a statement released by the Prime Minister's Office.
Lee, a Cambridge-educated lawyer, is widely credited with building Singapore into one of the world's wealthiest nations. He co-founded the People's Action Party (PAP), which has ruled Singapore since 1959 and led the newly born country when it was separated from Malaysia in 1965.
In Beijing's eyes, Lee Kuan Yew, the late founding father and leader of Singapore, was not only "an old friend of the Chinese people", but also "the founder of China-Singapore relations", according to China's previous official news releases about his visits.
Chinese media estimated that he had been to China more than 20 times, and he was known for his good personal relations with China's top figures, especially former leader Deng Xiaoping. Zhang Jiuhuan, the Chinese ambassador to Singapore from 2000 to 2004, noted that "it was a _ case" at the time that a foreign prime minister would visit China, as Lee did in 1976, in the absence of diplomatic relations between the two nations. Deng then paid back the visit, going to Singapore in 1978, in what Zhang described as a sensational trip.
Jin Canrong, a professor of international relations at Renmin University of China in Beijing, noted that Lee's No 1 contribution to China was his efforts in "sharing Singapore's successful experience in governance", adding that "China has benefited a lot" from this.
The China-Singapore Suzhou Industrial Park, inaugurated in February 1994 in Jiangsu province in East China, was proposed by Lee, who even went to the city in 1992 to inspect the site for the park.
Now, with the park serving as a role model for China's economic cooperation with foreign countries, more such industrial parks hosted or co-hosted by China have been established domestically and abroad.

According to the passage, which of the following statements is NOT true about McCurdy? | D | Read the passage and answer the question. | Passage:
It isn't often that an entire industry is symbolized in the figure of a single human being, and such is the case with Canadian aviation and the aircraft industry. The man is the Hon. John A. D. McCurdy and the life story of this still vigorous , distinguished Canadian is at once and at the same time the thrilling history of aviation's progress in Canada.
It all began one cold February day in 1909 at Baddeck, Nova Scotia, when John McCurdy confounded the critics by flying the Silver Dart, an aircraft designed by himself, for half a mile over the ice of Brasdeor Lakes. This was the first powered flight in Canada and the first by a British subject in the Commonwealth. McCurdy gave proof of his flying ability and of the development and the use of the aileron by being the first man in the world to carry out a figure high in the air. He became the first to pilot a flying boat, taking off from Long Island Sound. He flew the first airplane to Mexico. In 1911 he had made the longest flight to date, and that over open sea 90 miles from Key West to Havana. He won the first crosscountry race in Canada 40 miles from Hamilton to Toronto and he transmitted the first radio message from aircraft.
When World WarIIcame, McCurdy took on board supervisory authority for Canadian aircraft production by serving with the government in various senior positions.
Following World WarII, McCurdy was honored by being made lieutenant governor of Nova Scotia where he made Canada's first historic flight. He now lives in Montreal with a summer home in Baddeck, site of his first flight.

These young men were a different kind of prisoner from those we had seen before. They were brave, and hostile; they would not take orders, and shouted "Amandla!" at every opportunity. Their instinct was to confront rather than cooperate.
The authorities did not know how to handle them, and they turned the island upside down.
During the Rivonia Trial, I remarked to a security policeman that if the government did not reform itself, the freedom fighters who would take our place would some-day make the authorities miss us. That day had indeed come on Robben Island.
In these young men we saw the angry revolutionary spirit of the times. I had had some warning. On a visit with Winnie a few months before, she had managed to tell me through our coded conversation that there was a rising class of discontented youths who were violent and Africanist in beliefs. She said I should be aware of them.
The new prisoners were shocked by what they considered the inhuman conditions of the island, and said that they could not understand how we could live in such a way. We told them that they should have seen the island in 1964. But they were almost as sceptical of us as they were of the authorities. They chose to ignore our calls for discipline and thought our advice weak and unassertive .
It was obvious that they regarded us, the Rivonia Trialists, as moderates .After so many years of being branded a radical revolutionary, to be seen as a moderate was a novel and not altogether pleasant feeling. I knew that I could react in one of two ways: I could scold them for their disrespect or I could listen to what they were saying. I chose the latter.
Then some of these men, came into our section. I asked them to tell us about their movement and beliefs.
Shortly after their arrival on the island, the commanding officer came and asked me as a favour to address the young men. He wanted me to tell them to behave themselves, to recognize the fact that they were in prison and to accept the discipline of prison life.I told him that I was not prepared to do that. Under the circumstances, they would have regarded me as a follower of the authorities.

Five Ways to Rock the Rest of the Semester
With exams around the corner, how can you possibly pack in one more English word, let alone the causes of the Cold War? Don't worry. Here is our handy guide to help you
Power Down
So you stayed up too late last night reading Mockingjay for the fifth time. Oops! When you're that fired, your schoolwork suffers. Instead of studying inefficiently while you are sleepy, allow yourself a 15-minute afterschool power nap. Studies show that even a few minutes of shut-eye can improve memory and concentration.
Take Notes
Not quite grasping that super complicated concept in your chemistry class? You may need to change the way you take notes. Instead of recording every word your teacher says, try using visual hints like pictures, symbols and word bubbles. You can even switch computer fonts or pen color for the important stuff.
Dream On
Your bed's not just for zzz's. Experts say it may be good to study in bed, too. Why? We're able to absorb more right before bed because we're less distracted and the new information stays in our minds as we sleep. So, slide into bed with a textbook or notes, read for 15 minutes, and then turn off the lights for some sweet and smart dreams.
Brain Food
You're in the middle of a biology exam when your mind goes blank. You knew this stuff cold at home, but now you can't tell a ribosome from a chloroplast. What's going on? Your brain's in need of some refueling. Have some snacks like apple slices or cheese before class, and have plenty of water, too. If your teacher doesn't mind, pop in a piece of gum during an exam. Some scientists think the chewing increases the flow of oxygen to the brain.
Smart Move
Ugh! You're taking an English test and you cannot remember the past participle of "understand". What to do? Skip it. Test taking is all about timing, so don't waste it on tricky questions. Move ahead and answer everything you know before returning to the ones you don't. Chances are, once you get back to the toughies, you'll recall the answer or at the very least, you'll have a little more time to come up with one that works.
Question:
According to the passage, _ .
Choices:

With exams around the corner, how can you possibly pack in one more English word, let alone the causes of the Cold War? Don't worry. Here is our handy guide to help you
Power Down
So you stayed up too late last night reading Mockingjay for the fifth time. Oops! When you're that fired, your schoolwork suffers. Instead of studying inefficiently while you are sleepy, allow yourself a 15-minute afterschool power nap. Studies show that even a few minutes of shut-eye can improve memory and concentration.
Take Notes
Not quite grasping that super complicated concept in your chemistry class? You may need to change the way you take notes. Instead of recording every word your teacher says, try using visual hints like pictures, symbols and word bubbles. You can even switch computer fonts or pen color for the important stuff.
Dream On
Your bed's not just for zzz's. Experts say it may be good to study in bed, too. Why? We're able to absorb more right before bed because we're less distracted and the new information stays in our minds as we sleep. So, slide into bed with a textbook or notes, read for 15 minutes, and then turn off the lights for some sweet and smart dreams.
Brain Food
You're in the middle of a biology exam when your mind goes blank. You knew this stuff cold at home, but now you can't tell a ribosome from a chloroplast. What's going on? Your brain's in need of some refueling. Have some snacks like apple slices or cheese before class, and have plenty of water, too. If your teacher doesn't mind, pop in a piece of gum during an exam. Some scientists think the chewing increases the flow of oxygen to the brain.
Smart Move
Ugh! You're taking an English test and you cannot remember the past participle of "understand". What to do? Skip it. Test taking is all about timing, so don't waste it on tricky questions. Move ahead and answer everything you know before returning to the ones you don't. Chances are, once you get back to the toughies, you'll recall the answer or at the very least, you'll have a little more time to come up with one that works. | [

Which of the following is a way to save online time? | A | Read the passage and answer the question. | Passage:
If you've been joining in chat room conversations, or trading e-mails with net pals , you have become one of the millions who write in a special, short form of English.
Throughout the world, every night children and their elders are "talking" online-many of them are talking at the same time.
It's fast: trying talking to six people once. It's convenient: three or four words per exchange. It takes cleverness, concentration and quick fingers.
And it requires very simple language. There's neither time nor space for explanations. Why waste valuable time telling six friends you have to leave for a moment to take care of your little brother when BRB (be right back) will do?
Want to enter a conversation? Just type PMFJI (pardon me for jumping in).
Interested in whom you're talking to? Type A/S/L, the nearly universal request to know your pal's age, sex and location. You may get 15/M/NY as a reply from your pal.
If something makes you laugh, say you're OTF (on the floor), or LOL (laughing out loud), or join the two into ROTFL (rolling on the floor laughing).
And when it's time to get back to work or go to bed, you type GTG (got to go) or TTYL (talk to you later).
People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing feeling, as it takes more time to hold down the "Shift" key and use capitals. Punctuation is going too.

There are three machines in a factory. Machine A can put caps on 12 bottles in 1 minute. Machine B can put caps to 2 fewer bottles than Machine A. Machine C can put caps to 5 more bottles than Machine B. How many bottles can those three machines put caps on in 10 minutes? | Machine A can put caps on 12 x 10 = <<12*10=120>>120 bottles in 10 minutes.
Machine B can put caps on 12 - 2 = <<12-2=10>>10 bottles in 1 minute.
So in 10 minutes, machine B can put caps on 10 x 10 = <<10*10=100>>100 bottles.
Machine c can put caps on 10 + 5 = <<10+5=15>>15 bottles in 1 minute.
So in 10 minutes, machine C can put caps on 15 x 10 = <<15*10=150>>150 bottles.
Therefore, the three machines can put caps on 120 + 100 + 150 = <<120+100+150=370>>370 bottles in 10 minutes.

Which of the following statements is true according to the passage? | A | Read the passage and answer the question. | Passage:
My father was a foreman of a sugar-cane plantation in Rio Piedras, Puerto Rico. My first job was to drive the oxen that ploughed the cane fields. I would walk behind an ox, guiding him with a broomstick. For $ 1 a day, I worked eight hours straight, with no food breaks.
It was very _ work, but it prepared me for life and taught me many lasting lessons. Because the plantation owners were always watching us, I had to be on time every day and work as hard as I could. I've never been late for any job since. I also learned about being respectful and faithful to the people you work for. More important, I earned my pay; it never entered my mind to say I was sick just because I didn't want to work.
I was only six years old, but I was doing a man's job. Our family needed every dollar we could make because my father never earned more than $ 18 a week. Our home was a three-room wood shack with a dirty floor and no toilet. Nothing made me prouder than bringing home money to help my mother, father, two brothers and three sisters. This gave me self-esteem , one of the most important things a person can have.
When I was seven, I got work at a golf course near our house. My job was to stand down the fairway and spot the balls as they landed, so the golfers could find them. Losing a ball meant you were fired, so I never missed one. Some nights I would lie in bed and dreamt of making thousands of dollars by playing golf and being able to buy a bicycle.
The more I dreamed, the more I thought. Why not? I made my first golf club out of guava limb and a piece of pipe. Then I hammered an empty tin can into the shape of a ball. And finally I dug two small holes in the ground and hit the ball back and forth. I practiced with the same devotion and intensity . I learned working in the field -- except now I was driving golf balls with club, not oxen with a broomstick .

What can we conclude from the passage? | B | Read the passage and answer the question. | Passage:
Mail lay scattered across the kitchen table. I couldn't put off sorting through it any longer. I checked the envelopes, putting aside the ones addressed to my husband.
It had been over three years since Bob had died. To friends and family it looked like I had moved past the worst of my sorrow. I took care of my house, socialized and kept up with community. On the outside everything appeared to be normal. But inside I was anything but I worried I would never get better, never be myself again. They say sorrow has no set time limit, but I was so tired of feeling empty and hopeless. My sorrow was sharp and fresh as ever. It was like a wall of pressure in my chest, pressing my heart.
I picked up a piece of Bob's mail and held it out to tear in half, but stopped myself from cutting up the envelope. The letter was from an organization that funded a Haitian orphanage called _ . Its founder, Carol Hawthorne, had given a presentation at our church. Bob and I had donated, and Bob ended up on the mailing list to receive the newsletter with updates on the children.
I hadn't read one since Bob died. But just three months before, in January 2012, the country had been hit by a terrible earthquake. In my depressed state, it hadn't even occurred to me to wonder whether the orphanage had survived. I opened the newsletter and was surprised to find out that My Father's House was still standing. Of course now it was more crowded than ever. At the bottom of the page was an announcement about an upcoming trip to visit the orphanage in person. "I should go." The thought wouldn't leave me. I contacted Carol Hawthorne."What would I do if I go?" I asked."Build houses?"
"The Haitian people there are eager to work and they know what they're doing," said Carol. "What they need are raw materials, and we provide them. We also visit with the children. We go to clinics and schools, pass out supplies. You'll be very busy, I promise!" I reserved a seat but didn't mention it to any of my friends. Just a few weeks later, I was at the airport with seven strangers, waiting to board a plane to Haiti. Even after takeoff I wasn't really sure of what I was doing.
In Haiti we were met by Pastor Ronald Lefranc, the director of My Father's House. We piled into an old school bus and drove over uneven roads full of stones and mud. We passed women shaking under the weight of huge water buckets balanced on their heads. Piles of rubbish scattered across the landscape, and the land was covered with broken tents. Finally we pulled up to the orphanage. A crowd of children--52 in all--rushed up to greet us. I couldn't understand the words of the song they sang in Creole, but with the smiles on their faces I didn't need to. Each child planted a big kiss on my cheek.
Carol and Pastor Ronald led us into the main building. "What are those over there?" I asked, pointing to a collection of thin tents. "Is there not enough room in the building for all the children?"
"We have the room," said Pastor Ronald. "But many of these children came here after the earthquake. They still don't feel safe sleeping under a roof."
There was no sign of fear in the playroom inside. I played dolls and other games. Children I'd just met presented me with pictures they'd drawn and letters written in Creole. In the evening the children gathered in the dining room. They took turns reading aloud and then they all joined in song. The words were strange, but the tune sounded familiar.
They'd lost so much, yet were so joyful. In the evening the children gathered in the dining room. One of the older children stood up to speak and then they all joined in song. The words were strange, but the tune sounded familiar. The children settled down. In the silence, a quiet noise began.

The man bought the book because _ . | A | Read the passage and answer the question. | Passage:
The Touchstone
When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book, and so a poor man, who could read little, bought it for very little money.
The book wasn't very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the "Touchstone"! The touchstone was a small pebble that could turn any common metal into pure gold.
The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.
So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold, throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea. The days continued over a long period of time.
One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
So it is with opportunity. Unless we are careful, it's easy to fail to recognize an opportunity when it is in hand and it's just as easy to throw it away.

One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
So it is with opportunity. Unless we are careful, it's easy to fail to recognize an opportunity when it is in hand and it's just as easy to throw it away. | [

What's George Garritan's attitude toward the "gap year"? | B | Read the passage and answer the question. | Passage:
Dennis Sinar, 51, a doctor from Washington, N. C., is quick to explain why he took a yearlong break from his job. "I was pretty burned out after practicing medicine for 26 years. I needed a recharge." So he took a "gap year", from July 2011 to June 2012, to explore things like ancient buildings, antique restoration, and traditional Eastern medicine, in locations including Alaska, Nepal and Romania.
"Taking a break from work is an excellent way for adults to go into a new career or refresh an old one," said Holly Bull, president of the Center for Interim Programs in Princeton, N, J., which sets up gap-year programs. The group works mainly with college-age students, but it has also served older adults since it was formed 28 years ago. "In recent years, mid-career breaks have been gaining more interest," she said. A report on adult gap years published this year by a market research company also described the potential American market for gap years as a "sleeping giant."
"A gap year is a challenge for the older individual to step out of a comfort zone and take a risk. I enjoyed that side most." said Dr. Sinar, who kept a daily blog about his experience. His time studying Eastern medicine "reaffirmed the reasons I went into health care," said Dr. Sinar, who returned to practice medicine at his old job, although he works fewer days. "I use those experiences to provide my patients with more care," he added. "And I listen better than I did before."
George Garritan, chairman of the Department of Leadership and Human Capital Management at New York University, certainly agrees with Dr. Sinar. He said a gap-year experience could be worthwhile for employees and companies. For employees, investing in themselves and improving skill sets is a move that will benefit throughout their career. He added that returning employees feel refreshed and have given more thought to their career. For companies, offering unpaid leaves makes good sense for attracting and keeping talented employees.
"My hope is that this takes off," Dr. Garritan said. "We're all thinking, 'What's my next act?' "

What can we infer from the passage about the Cultural Revolution? | A | Read the passage and answer the question. | Passage:
Mo Yan was born in 1955, in GaomiCounty inShandongprovince to a family of farmers. Mo was 11 years old when theCultural Revolutionwas launched, at which time he left school to work as a farmer. At the age of 18, he began to work at a cotton factory. During Mo's teenage years, with a series of political campaigns from theGreat Leap Forwardto theCultural Revolutiongoing on, his access to literature was limited to novels in thesocialist realiststyle under Mao Zedong, which centered largely on the themes of class struggle and conflict.
At the close of the Cultural Revolution in 1976, Mo joined in the People's Liberation Army(PLA), and began writing while he was still a soldier. He began his career as a writer in thereform and opening upperiod, publishing dozens of short stories and novels in Chinese. His first novel was Falling Rain on a Spring Night, published in 1981. In 1984, he received a literary award from the PLA Magazine, and at the same year he began attending the Military Art Academy, where he first adopted the pen name of Mo Yan. He published his firstnovella , A Transparent Radish in 1984, and released Red Sorghum in 1986, launching his career as a nationally recognized novelist. In 1991, he obtained a master's degree in Literature from Beijing Normal University.
"Mo Yan" -- meaning "don't speak" in Chinese -- is his pen name. In an interview, he explained the name came from a warning from his father and mother not to speak his mind while outside, because of China's revolutionary political situation from the 1950s, when he grew up.
Mo Yan's Red Sorghum Clan is about the generations of a Shandong family between 1923 and 1976. The author deals with great changes in Chinese history such as the War of Resistance Against Japanese Invasion, theCommunist Revolution, and theCultural Revolution, but in an unusual way, for example from the point of view of the invading Japanese soldiers. His second novel, The Garlic Ballads, is based on a true story of the farmers of Gaomi Township fighting against a government that would not buy its crops.

Tom, an avid stamp collector, has 3,000 stamps in his collection. He is very sad because he lost his job last Friday. His brother, Mike, and best friend, Harry, try to cheer him up with more stamps. Harry’s gift to Tom is 10 more stamps than twice Mike’s gift. If Mike has given Tom 17 stamps, how many stamps does Tom’s collection now have? | Twice the number of stamps given by Mike is 17 stamps * 2 = <<17*2=34>>34 stamps
Harry therefore gave Tom 10 stamps + 34 stamps = <<10+34=44>>44 stamps
Combining both gifts gives a gift total of 44 stamps + 17 stamps = <<44+17=61>>61 stamps
The total number of stamps in Tom’s collection is now 3000 stamps + 61 stamps = <<3000+61=3061>>3061 stamps

The writer says a critic _ . | D | Read the passage and answer the question. | Passage:
Criticism is judgement.A critic is a judge.A judgement study and think about the material presented to him, accept it, correct it, or reject it after thinking over what he has read, watched or heard.
Another word for criticism is appreciation.When I criticize or appreciate some objector another, I look for its good points and bad points.In reading any printed or written matter, I always have a pencil in hand and put any comments in the book or on a separate paper.In other words, I always talk back to the writer.
That sort of critical reading might well be called creative reading because I am thinking along with the author, asking him questions, seeing whether he answers the questions and how well he answers them.I mark the good passages to store them in my memory piece of writing; where, how and why could or should I improve upon it?
You might think that doing what I suggested is work.Yes, it is, but the work is a pleasure because I can feel my brain expanding, my emotion reacting and my way of living change.
Reading exercises is a great influence on a person.If pictures, still or moving, accompany the reading, the memory will retain the material for a long time.

Escaping a fire is a serious matter.Knowing what to do during a fire can save your life.It is important to know the ways you can use and show them to everyone in the family,such as stairways and fire escapes,but not lifts.
From the lower floors of the buildings,escaping through windows is possible,learn the best way of leaving by windows with the least chance of serious injury.
The second floor window is usually not very high from the ground.An average person,hanging by the finger-tips will have a drop of about six feet to the ground.It is about the height of an average man.Of course,it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help.Be sure to keep the door closed.Or smoke and fire may be drawn into the room.Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked into the room.
On a second or third floor,the best windows for escaping are those that open onto a roof.From the roof a person can drop to the ground more safely.Dropping onto cement might end in injury.Bushes and grass can help to break a fall.

When an animal is in a negative mood state, _ . | A | Read the passage and answer the question. | Passage:
How can we measure animals' emotions? A new study of animal's emotions suggests that, as in humans, emotions can tell animals about how dangerous their world is, and guide the choices that they make. The article of the study by Bristol University's professor Mike Mendl was published online.
An animal living in an environment where it is often threatened by predators will develop a negative emotion or "mood", such as anxiety. However, one in an environment with plenty of opportunities to get resources for survival will be in a more positive mood state.
The researchers say that these emotional states not only show the animal's experiences, but also help it decide how to make choices, especially in unclear situations. This could have good or bad results. An animal in a negative mood state will make a safety-first with a "pessimistic" response to an unclear event. For example, it considers a noise in the grass as a signal of the predator. At the same time, an animal in a positive mood state will benefit from a more "optimistic" response. It considers the noise as a signal of prey .
Professor Mike Mendl, head of the Animal Welfare and Behavior Research Group at Bristol University's School of Clinical Veterinary Science said, " We can use "optimistic" or "pessimistic"decision-making as a symbol of an animal's emotional state. Recent studies by our group and others suggest that this is a _ new approach to studying a variety of animal species."
"Public interest in animal welfare remains high, with widespread concern about the way in which animals are treated, used and included in society. To understand how animals should be treated, we need to better understand their emotional lives," Mike Mendl said. The researchers believe Mike Mendl's study can help them to better understand and assess an animal's emotions.

Carrying a mini backpack can help you because | A | Read the passage and answer the question. | Passage:
Traveling should be easy and enjoyable, and one of the ways to make sure your trip remains fun is to know exactly how to keep your valuables safe.
If you are traveling alone, distribute your money through your luggage. Place most of it in your main suitcase or bag. Make a rough estimate of how much money you will spend on the journey, till you reach your destination. Place this money in a different wallet and carry this in your pocket. Spend from this pocket till you get to your destination. If you are travelling with someone, distribute the money among yourselves.
Instead of wearing your jewels, you can put your jewels at the bottom of your suitcase or bag. DO NOT carry in your purse, just in case it is stolen; or in case you misplace your purse. In addition, if you are going to be frequently opening your purse for things like tickets and phone numbers, what if you accidently just drop them.
Have you ever seen a mini backpack purse? It looks really fashionable and is very smart. Plus, It's really convenient to use. The best thing to do is to hang the mini backpack purse in the front, like a baby carrier. There are two big advantages to do this; one, your hands remain free to carry your luggage and other things; and two, your purse is always monitored, and is just under your nose!
Credit cards are very useful in many ways. But if you misplace your credit card, it is quite easy for someone else to find it and use it to his/ her maximum benefit before you even realize you have lost it! If you lose cash, you lose only that much cash as you are carrying. But a lost credit card means the money in your bank account is lost. So always try to use cash instead of credit card while traveling
Question:
Carrying a mini backpack can help you because
Choices:
A. it is convenient to carry and monitor.
B. it is easier to carry your baby.
C. it reduce the burden on your back.
D. it can use to carry more things. | Answer: A | reading | null | null | null | null | null | null | null | null | high10801.txt | Traveling should be easy and enjoyable, and one of the ways to make sure your trip remains fun is to know exactly how to keep your valuables safe.
If you are traveling alone, distribute your money through your luggage. Place most of it in your main suitcase or bag. Make a rough estimate of how much money you will spend on the journey, till you reach your destination. Place this money in a different wallet and carry this in your pocket. Spend from this pocket till you get to your destination. If you are travelling with someone, distribute the money among yourselves.
Instead of wearing your jewels, you can put your jewels at the bottom of your suitcase or bag. DO NOT carry in your purse, just in case it is stolen; or in case you misplace your purse. In addition, if you are going to be frequently opening your purse for things like tickets and phone numbers, what if you accidently just drop them.
Have you ever seen a mini backpack purse? It looks really fashionable and is very smart. Plus, It's really convenient to use. The best thing to do is to hang the mini backpack purse in the front, like a baby carrier. There are two big advantages to do this; one, your hands remain free to carry your luggage and other things; and two, your purse is always monitored, and is just under your nose!
Credit cards are very useful in many ways. But if you misplace your credit card, it is quite easy for someone else to find it and use it to his/ her maximum benefit before you even realize you have lost it!

The mobile phone rule is just common polite behavior. Most people today have a mobile phone. In fact, many people can't imagine how they ever get along without them.

What does the writer think of the Internet? | D | Read the passage and answer the question. | Passage:
Today almost everyone knows computers and the Internet. If I ask you "What is the most important in your life ?" maybe you will say "Computers and the Internet."
The first computer was made in 1946. It was very big but it worked slowly . Today computers are getting smaller and smaller. But they work faster and faster. What can computers do?
A writer has said, "people can't live without computers today."
The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, write letters, do shopping, play games or make friends.
Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don't know their real names, ages, and even sex . They are so interested in making the "unreal friends" that they can't put their hearts into study. Many of them can't catch up with others on many subjects because of that.
We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.

According to the text, Agmlauncher is _ bottled water. | C | Read the passage and answer the question. | Passage:
Despite organized anti-bottled-water campaigns across the country and a noisy debate about bottled water's environmental effect, Americans are buying more bottled water than ever.
---------------------------------------------------------------------------------------------------
Why do so many people seem to think they should have any input on what other Americans choose to buy or do?
If they want to buy bottled water, let them.
If they want to eat fast food, let them.
If they want to smoke pot, let them.
----Barackalypse
People just get tired of paying for others' bad behavior. If many people eat too much fast food, you pay higher insurance bill. If many people frequently buy bottled water, your trash bills go up and landfills fill up quickly.
It's about personal responsibility, which really should be a basis of our society.
----Bdbr
So? This is the price you pay to live in a free society. You want to control the life of another just so you can save a little money? What would you say when someone do the same to you?
----Norman619
I'm just glad there are still people who still believe personal responsibility is a good thing. We make your life cheaper and less bothersome.
----Yoyo
What a waste of money. It's fine when you're on the road and you need a cold drink, but people who buy cases of bottled water for home are completely crazy.
----Agmlauncher
I wish we all can find a way to improve things and benefit from this. The environment needs a lot of help but businesses will always work on what people would need and demand. Is this part of the trade-off? Hope we can find better ways.

The purpose of the Exercise Flood Call is to _ . | D | Read the passage and answer the question. | Passage:
A few months ago, millions of people in London heard alarms all over the town. The Emergency Services, the Fire Departments, the Police, hospitals, and ambulances stood by, ready to go into action. In railway underground stations, people read notices and maps that told them where to go and what to do in the emergency. This was Exercise Flood Call, to prepare people for a flood emergency. London wasn't flooded. In 1928, people living in Westminster, the heart of London, drowned in floods. And in 1953, one hundred people, living on the eastern edge of the London suburbs were killed, again, in the floods. At last, Greater London Council took actions to prevent this disaster from happening again. Though a flood wall was built in the 1960s, Londoners still must be prepared for the possible disaster. If it happens, 50 underground stations will be under water. Electricity, gas and phone services will be out of action. Roads will be drowned. It will be impossible to cross any of the bridges between north and south London. Imagine: London will look like the famous Italian city, Venice. But this Exercise Flood Call didn't cause panic among Londoners. Most people knew it was just a warning. One lady said, "It's a flood warning, isn't it. ? The water doesn't look high to me."

The passage mainly tells us _ . | A | Read the passage and answer the question. | Passage:
Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.
Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.

Which of the following about Plato's Closet is NOT true? | B | Read the passage and answer the question. | Passage:
The tough economy is bringing new shoppers to the secondhand market. Plato's Closet in Charlotte, NC is a private company which mainly buys and sells used clothes. While Charlotte has outstanding secondhand stores offering high-end and sophisticated brands for women, most of their stock applies to adults. Plato's Closet targets teens and those in their 20s.Plato's Closet, with stores in Matthews and the university area, sells clothes and accessories that are currently popular at up to 70 percent off retail prices .
The two hottest brands, for buying and selling, are Hollister and Abercrombie & Fitch. Even though the offerings tend to be suitable for young people, there are a variety of shoppers at Plato's Closet of varying ages. Women in their 30s; 40s and older could easily find a purse, jacket or piece of jewelry they like.
Customer Beth Gibbs, 52, who has three teenage daughters, said she used to shop at name-brand stores, but "this year I'm shopping more in secondhand stores", because of the economy.
If you're selling
Unlike higher-end resale stores which usually work on consignment , Plato's Closet buys on the spot.
Items can be gently used, but must be in very good condition.
Clothes should be less than two years old and styles should be the same as those still being sold at the shopping center.
There is no negotiation; prices are set company-wide. If what you sell amounts to $30 or less, they'll give you cash. More than that, you'll get a Visa cash card.
Secondhand success
Don't get discouraged if you can't find something on your first trip. Resale shops are always getting new lists of goods and change their styles with each season.
Be sure to check each piece carefully before buying.

Budgeting helps _ . | A | Read the passage and answer the question. | Passage:
Many families in the prefix = st1 /United Stateshave a larger income now than ever before, but people are finding it difficult to make ends meet anyway. Almost everyone is wondering, "What happens to all my money? I never seem to have anything left to put away."
Why isn't a dollar worth as much as it used to be? One dollar is always worth the same amount, that is, 100 cents. But the value of a dollar is how much it can buy. The value of money depends on the cost of living. Economists say that the cost of living is the money that a family must pay for the necessities of life such as food, housing or rent, clothes and medical expenses. For many years now the cost of living has increased greatly, so the value of the dollar has decreased. When a dollar has a low value, you cannot buy as many things with it.
No one fully understands why the cost of living keeps increasing, but economists believe that workers and producers can make prices go up. As workers earn more money, they have more money to spend, so they demand more goods. If there is a great demand for certain goods, the prices of these goods go up. At the same time, if there's a shortage of goods, the price also goes up. For example, if everyone wants to buy more and more gas, the price of gas goes up. When companies withhold gas from buyers, they can also make the price of gas go up.
Families need to know what happens to their money. They need to make their income meet the cost of living, so many people plan a family budget. A budget is a list of monthly expenses. If your expenses add up to more than your income, you must find ways to save money. Maybe you're spending too much on entertainment. Or if you're spending too much on clothes, you may want to sew your own clothes. Budgeting helps you spend your money wisely as the cost of living increases.

If you have referred to the map of the park, you _ | A | Read the passage and answer the question. | Passage:
As for visiting Walt Disney World. People usually have trouble in arranging. The following will give you some practical suggestions on paying a valuable visit to the famous park.
When to go?
While it's always busy, Disney World is slightly slower between mid-January and March. It's summer when the visitors , combined with the heat and humidity , are crowded. Your best choice is either early in the morning or late in the day--- often you can enjoy more rides in the first or last two hours of the day than you can the entire rest of the day combined.
Where to stay?
The question: to stay on Disney World Resort property or not. Disney World offers three resort pricing: Deluxe , Moderate, and Value, with good facilities and in-hotel attractions. That said, they all offer "Extra Magic Hours"(early access to the theme parks), guaranteed entry when the parks are over-crowded, and frequent shuttle service to the many attractions. Off-property hotels will have shuttle transfers, but often at less regular intervals ,wasting more time in transport. You'll also need a rental car, which adds to the expense, making up for saving in the hotel rate. The "Magic Your Way Package" is a good value if you have a large family.
What to do?
Make use of the "Fast Pass" , which , for no extra cost, allow you to insert your entrance ticket into a particular machine at the attraction and receive a schedule ride time a little later on. For example, use your Fast Pass ticket at a ride just before getting lunch. Once you're done eating, you can return to the ride and jump right on during the busiest time of day. At the Animal Kingdom, the animals are most active either early or late in the day, so plan accordingly. Thankfully _ is fit for the least busy times of day in the park. Study the map of the park the night before to plan your visit. You'll save time by knowing where things are and where you're headed.

Hi, I'm your tooth. I've been asked to represent the rest of your teeth. We need your help. We like to be clean when you show us off with your big, wide smiles.
First, let me tell you a little about us. You weren't born with the baby teeth, they developed when you were about six or seven months old. You went from milk to real food in no time thanks to your twenty primary teeth. Eventually, they loosened and fell out, one at a time, probably about the time you were six or seven years old.
Then we came into your life. We are your permanent teeth, all twenty-eight of us. Some people may even have thirty-two depending on those wisdom teeth in the back. Sometimes they are able to help, and sometimes they cause trouble. Many times wisdom teeth are sideways and have to be pulled. Some people don't even have them at all!
On a more personal note, I am an incisor, and you have seven more just like me, here in the front of your mouth. We do the biting on those chocolate chip cookies you like so much. Next to us are the canines, four sharp teeth, two on either side. Their job is to tear food; pizza is a good one for them. Behind them are eight premolars and eight to twelve molars, depending on those wisdom teeth. The molars do the majority of the work chewing the food that you eat. They do a great job on those carrots you like so much!
Did you know we not only help you bite and chew but also help you talk? That's right. Try to say "tooth" without letting your tongue touch the back of your teeth. It sounds pretty funny, doesn't it?

After the twin's father died, the department store was managed by _ . | C | Read the passage and answer the question. | Passage:
Gary and Gavin were twin brothers who worked in a department store owned by their father. After their father had passed away, they took over the store. Everything went well until the day a twenty-dollar bill disappeared. Gary had left the bill on the cash register. But when he returned, the money was gone.
Gary then asked his brother Gavin, "Did you see that twenty-dollar bill on the cash register?" Gavin said that he had not. But Gary did not let it go and kept questioning. "Twenty-dollar bills can't get up and walk away by themselves! Surely you must have seen it." There was accusation in Gary's voice. Tempers began to rise and anger grew. "I said I didn't see it!" Gavin raised his voice.
The quarrel divided the young men and they could no longer work together. Later, a wall was built in the center of the store. For twenty years, they never said a word to each other.
One day, a strange man came to the store. He walked in and asked Gary, "How long have you been here?" Gary replied that he'd been there all his life. "Then you are the person I'm looking for, since I must tell you the truth," the customer said emotionally. "Twenty years ago, I was totally _ and hungry. I entered this store from the back door and saw a twenty-dollar bill on the cash register. And I took it. All these years I hadn't been able to forget that. I had to come back and ask for your forgiveness ."
The stranger felt very surprised when seeing tears come to the eyes of the middle-aged man in front of him. "Would you please go next door and tell the same story to the man in the store?" Gary asked. Then something surprised the stranger even more --- after hearing his story, the two middle-aged men hugged each other and cried together in the front of the wall of the store.
After twenty years, the wall of anger that set them apart finally came down.

But Mailer will be remembered as much for his personality as for his writing. He was rude and bad-tempered. He violently attacked other authors and even wounded one of his six wives.
However, this never stopped Mailer from being successful. People always wanted to read his books. His provocative writing style and willingness to deal with difficult subjects made his books bestsellers.
"He was willing to take risks with just about everything," says the author Gore Vidal. "He had a radical imagination, a way of approaching subjects that was never boring."
In a career that lasted six decades, Mailer wrote about a wide variety of subjects from history and politics to sport and celebrities. But he was most famous for writing novels and he twice won the Pulitzer Prize.
His best book was The Naked and the Dead, a story about the tensions between American soldiers fighting Japan in World War II. Drawn on his own experiences as a soldier, it is a study of men at war examining their cruelty and bravery.
Mailer's brilliance as an author was his ability to capture human behavior. He did so through interesting characters, realistic dialogue and rich descriptions. The author William F. Buckley said, "He created the most beautiful metaphors in the English."
Mailer leaves behind more than 40 books as his literary legacy . However, he never achieved his life's goal. He wanted to write what he called the "big one", the greatest novel ever written about America. Well, at least it wasn't for a lack of trying.

Which is NOT the reason why the author didn't tell her mother she was getting married? | C | Read the passage and answer the question. | Passage:
After much thought,I came up with a brilliant plan.I worked out a way for Rich to meet my mother and win her over.In fact,I arranged it so my mother would want to cook a meal especially for him.
Rich was not only not Chinese and he was a few years younger than I was.And unfortunately,he looked much younger with his curly red hair,smooth pale skin,and the splash of orange freckles across his nose.He was a bit on the short side,compactly built.In his dark business suits,he looked nice but easily forgettable,which was why I didn't notice him the first year we worked together at the firm.But my mother noticed everything.
"So what do you think of Rich?"I finally asked,holding my breath.
She tossed the eggplant in the hot oil,angry hissing sound."So many spots on his face,"she said.
"They are freckles.Freckles are good luck."I said a bit too heatedly in trying to raise my voice above the noise of the kitchen.
"Oh?"She said innocently.
"Yes,the more spots the better."
She considered this a moment and then smiled and spoke in Chinese:"When you were young,you got the chicken pox.So many spots,you had to stay home for ten days.So lucky,you thought."
I couldn't save Rich in the kitchen.And I couldn't save him later at the dinner table.
When I offered Rich a fork,he insisted on using the slippery ivory chopsticks.Halfway between his plate and his open mouth,a large chunk of redcooked eggplant fell on his brand new white shirt.
And then he helped himself to big portions of the shrimp and snow peas,not realizing he should have taken only a polite spoonful.
He declined the new greens,the tender and expensive leaves of bean plants.He thought he was being polite by refusing seconds,when he should have followed my father's example,who made a big show of taking small portions of seconds,thirds and even fourths,always saying he couldn't resist another bite and then groaning he was so full he thought he would burst.
But the worst was when Rich criticized my mother's cooking and he didn't even know what he had done.As is the Chinese cook's custom,my mother always made modest remarks about her own cooking.That night she chose to direct it toward her famous steamed pork and preserved vegetable dish,which she always served with special pride.
"Ai!This dish not salty enough,no flavor,"she complained,after tasting a small bite.
This was our family's cue to eat more and proclaim it the best she had ever made.But before we could do so,Rich said,"You know,all it needs is a little soy sauce."And he proceeded to pour a riverful of the salty black stuff on the china plate,right before my mother's horrified eyes.
And even though I was hoping throughout the dinner that my mother would somehow see Rich's kindness,his sense of humor and boyish charm.I knew he had failed miserably in her eyes.
Rich obviously had a different opinion on how the evening had gone.When we got home,I was still shuddering, _ remembering how Rich had firmly shaken both my parents'hands with that same easy familiarity he used with nervous new clients."Linda,Tim,"he said,"we'll see you again."My parents'names are Lindo and Tin Jong,and nobody except a few older family friends ever calls them by their first names.
"What did she say when you told her?"I knew he was referring to our getting married.
"I never had a chance,"I said,which was true.How could I have told my mother I was getting married,when at every possible moment we were alone,she seemed to remark on how pale and ill he looked.
Rich was smiling."How long does it take to say,Mom,Dad,I am getting married?"
"You don't understand.You don't understand my mother."

Beijing will experience sandstorms every March and April mainly because of _ . | A | Read the passage and answer the question. | Passage:
Until late April, northern China had experienced eight severe sandstorms this year alone, worsening the air quality in half the region's cities.
This year's sandstorms are considered more severe than before. Not only are they increasing in frequency and having more serious effects on air quality, but they are also occurring earlier in the season and affecting a wider area. The timing of the first sandstorm moved up by a week this year, and the sandstorm-affected area has extended beyond 3 million square kilometers.
The reason for the frequent dust storms is worsening desertification in China's northern areas, caused by a combination of warm, dry weather and the rapid spread of agriculture. The dust-affected area is likely to expand to the northeast in the near future as a large area of grassland in Inner Mongolia's northern plain turns rapidly to desert.
Due to its lack of rainfall and overall surface dryness in the spring, Beijing experiences sandstorms every March and April. The most recent sandstorm hit the capital on April 17 and was the worst in five years. For about 40 days every year, the pollutants cannot be diffused, as the city's location makes it a natural container for accumulating sand and dust. Rapid urban development is affecting Beijing's air quality as well. To _ the dust from hundreds of new construction sites, authorities have issued rules asking builders to cover all working areas, pack down loose dirt, and wash vehicle tires when leaving the sites.

Read the following interview with Dr John Bass, an international shark specialist who has spent many years studying sharks:
First of all, doctor, are all sharks dangerous?
No, they aren't. There are about 250 different kinds of sharks, but fewer than 30 of them are dangerous to humans. Certain sharks are very aggressive and we should fear them, but the danger of shark attacks is much lower than most people think.
So which sharks are dangerous?
The Great White shark is the most dangerous. Then there is the Tiger shark, which other sharks are afraid of, and the Blue shark. Both of them are very fast and dangerous.
Which are the biggest and smallest sharks?
The Whale shark is the biggest shark in the world. It grows up to 15 m in length and weighs as much as six large cars. The smallest shark, which is found near prefix = st1 /Japan, could fit into the palm of your hand because it is only 15-20 cm long.
Do all sharks have teeth ?
Yes, they do. Most sharks have hundreds, sometimes even thousands, of sharp teeth. These are arranged in rows of four or more. They fit quite loosely in the jaw. When the front ones break off or fall out, spare teeth move forwards from the rows behind: Sharks get a new set of teeth every two weeks. In 10 years, a Tiger may lose as many as 24,000 teeth!
That's lots of teeth! What kind of food do sharks eat?
Most sharks feed on small fish, and they keep the oceans healthy by eating sick and injured fish. However, hungry sharks will eat almost anything, including smaller sharks and even rubbish. Inside one Tiger shark which was found, there was a tin can, a bicycle tyre , a leather wallet and an alarm clock!
And how do sharks find their food, doctor?
A shark's sense of smell is excellent. It will follow the smell of blood across thousands of metres of ocean. They also see well, and they have good hearing. Sharks can feel movement in water very easily too, and it is possible for them to feel a fish moving as far as 30 m away.

What is responsible for our sense of balance? | null | Answer the following science question clearly and accurately. | What is responsible for our sense of balance? | our ears | science | null | null | null | our feet | our eyes | our limbs | our ears | The ears are also responsible for the sense of balance. Balance is the ability to sense and maintain body position. The semicircular canals inside the ear (see Figure above ) contain fluid that moves when the head changes position. Tiny hairs lining the semicircular canals sense movement of the fluid. In response, they send nerve impulses to the vestibular nerve , which carries the impulses to the brain. The brain interprets the impulses and sends messages to the peripheral nervous system. This system maintains the body’s balance by triggering contractions of skeletal muscles as needed. | null | null | null |
