Question:
In the 1950s, a family that owned a farm near Beulah, Michigan kept a bull chained to an elm . The bull paced around the tree, dragging the heavy iron chain, which led to a groove in the bark . The groove deepened over the years. Though for whatever reason, it did not kill the tree. After some years, the family took their bull away. They cut the chain, leaving the loop around the tree and one link hanging down. Then one year, agricultural disaster struck Michigan in the form of Dutch Elm Disease. All of the elms lining the road leading to the farm became infected and died. Everyone thought that the old elm would be the next. The farm owners considered doing the safe thing: pulling it out and cutting it up into firewood before it died. But they simply could not bring themselves to do it. It was as if the old tree had become a family friend. So they decided to let nature take its course. Amazingly, the tree did not die. Nobody could understand why it was the only elm still standing in the county! Plant experts from Michigan State University came out to observe the tree. They observed the scar left by the iron chain, now almost completely covered by bark. The experts decided that it was the chain that saved the elm's life. They reasoned that the tree must have absorbed so much iron from the chain that it became immune to the virus. It's said that what doesn't kill you will make you stronger. Or, as Earnest Hemingway put it, "Life breaks us all, but afterwards, many of us are strongest at the broken places." What would be the best title for the passage?
Choices:
A. Let nature take its course
B. Strengthened by our wounds
C. Constant dripping wears away a stone
D. Bend, but don't break

Question:
Prana was a beautiful dog, whose name means "breath of life". Although he died several years ago, I can still remember the days we spent together and what he has taught me about love. I have two apple trees in the garden. Prana loved apples. When he went outside, he'd catch an apple and take it into the house to eat later. The apples had been on the ground and were often dirty so I wasn't always happy that Prana had brought them into the house. It was an autumn day in America, but it was very cold. A big snow fell and we had not done anything for its coming. On that special day, Prana went outside and I watched him through the window. I noticed that he was madly digging holes and bringing the apples to the ground so they could be seen above the snow. I did not know why he was doing this. He seemed to want to do something special. When I called him back, he had his usual one apple in his mouth. About five minutes later, I looked outside. The garden was completely covered with birds. Prana had dug up all those apples for his bird friends to eat. He knew that they wouldn't have stored enough food for the coming winter! On the snowy day, Prana _ .
Choices:
A. ate up all the apples
B. dug holes to put the apples in them
C. brought the apples under the snow to the ground
D. left the house and died

Question:
Gardening can be a very relaxing hobby for many people and this wonderful experience is not just for adults. Children are interested in gardening as well, if given the chance to explore nature and science in this way. Gardening can bring joy to both children and their parents alike, especially when the experience is shared together. The time that is spent gardening together builds precious memories within their hearts and minds for years to come. When you are gardening with your children, try to give them their own special area. Keep their area in the center of the best soil and light, as you want to make sure of a successful gardening experience. Plastic tools easily break and are difficult to use in the dirt, so when you are gardening with your children, give them real tools to use if possible. Even offering to let them use your tools is a way to admit the worth of the work they are doing. It is also important to talk with your children about the whole process of gardening, from planting to the harvest. They need to understand how things work and the importance of what they are doing. Show off the children's gardening work by taking friends and visitors for a walking tour through the garden and point out the children's particular spot. When you give attention to the children's work, this is a great motivation for children to continue wanting to be involved. Do not force children to take part when they are in a bad mood or if they are becoming bored. Instead, allow them to do something different, like building a scarecrow ! This makes the gardening experience even more interesting. As you work together side by side with your children, you will encourage a love of the land in them, as well as create lasting memories of time spent with you. Why should you introduce your children's work to your friends?
Choices:
A. It makes your friends believe your children are smart.
B. It helps you gain more confidence in your children.
C. It encourages children to continue doing such work.
D. It attracts your friends to take part in your gardening.

Question:
Rowena and Billy Wrangler are model high school students. They study hard and do extremely well on achievement tests. And next year,Rowena will be attending Harvard University.Billy,her younger brother,hopes to go to Cornell.What makes Rowena and Billy different from most students is that they don't go to school.In fact,they've never been to school.Since kindergarten,they've studied at home.Like many of more than one million people who receive home schooling in the United States, they feel as if they've gotten a good education. The home-schooling trend began in the U.S.in the 1980s with parents keeping their children out of public schools so they could provide religious education at home. Today,as the home-schooling trend continues to grow,parents are more likely to consider home schooling as an option because they believe schools don't do a very good job of teaching and are occasionally dangerous places.But can parents really do a better job? The answer in many cases is yes.In many studies,students taught at home ranked average or above average when compared to students who went to public schools.More importantly,these students were often more self-directed and have a greater depth of knowledge.They were well prepared for academic challenges. One such student,Robert Conrad, now a sophomore at university, claims he really learned how to study and schedule his time during his eight years of home schooling.Still, not every student is as successful as Robert. "For every home-schooling success story,there are an equal number of failures."states Henry Lipscomb,an educational researcher."There are just so many disadvantages that students taught at home have to overcome." For example,they have fewer chances to get in touch with others of their own age.Consequently,they sometimes lack the usual social skills."No matter what,though,"states Lipscomb,"home-schooling is a growing trend.I think we'll be seeing more and more of this." According to the article, what is NOT the advantage of being educated at home?
Choices:
A. Home is a safer place for children.
B. Students taught at home are more self-directed.
C. Students taught at home have a greater depth of knowledge.
D. Students taught at home can go to good universities.

Question:
I think it's really very good to be a doctor. On the one hand, you can save people; on the other hand, they share their experiences of life with you. I've been a doctor in Los Angeles. To be frank, my work is terribly busy but interesting. I can always meet patients in different conditions. One 'of my patients is a successful businessman. Cancer has changed his _ on life. " Happiness is like a cookie in a boy's hand, " he said. "If a young kid gets the cookie, everything will be good. With no cookie, life loses its color. When a boy becomes a man, the cookie may turn into money, a new car, or a beautiful house. " "It took me many years to understand that the cookie never makes you happy for long. If the cookie is in front of you, you may care for it. But sometimes you may not get a chance to eat it, and then you are busy trying not to lose it. Having the cookie is not what life is about. After having cancer, for me, the cookie starts to lose its meaning. It is the most important that you can live a happy life with or without the cookie, " he said. ,.

Question:
How many times do you have to fail at something in order to succeed? Did you know that Thomas Edison failed 10,000 times while trying to invent the light bulb? He certainly had a "learn and do" attitude! He was able to turn each failed experiment into a successful way to invent the light bulb. So what can we learn from this? You can adopt the "fail forward" strategy too. In reality, none of us are failures. It's true that we will experience times of defeat, problems, and disasters, but remember, each one of us is meant to succeed in life. However, we must choose our fate. Henry David Thoreau said, "Men are born to succeed, not to fail." We can never be forced into having a happy and successful life. Whether or not you experience success or failure is completely controlled by what you think and do. You are the only one who can choose the thoughts that will keep you from achieving the abundant life and joy that you are meant to have. No matter how difficult things may seem, say to yourself, "I choose to be a happy and successful person." Why do some people get what they want and others fail? I believe that getting what you desire in life takes planning, and it doesn't just happen by luck. So how do we plan for success? It has been proven that successful people do things more differently than unsuccessful people. They recognize the patterns of success and follow them; one of those patterns is planning. They plan what they think and do, which sets them apart. They know exactly what they desire, have an intelligent plan for getting it, and then work their plan. They know what success will cost them in terms of time, energy, and results, and they devote the right resources toward making their plans happen. Which of the following would match the text?
Choices:
A. All roads lead to Rome.
B. Think twice before you act.
C. No pains, no gains.
D. Failure is the mother of success.

Question:
If sustainable competitive advantage depends on workforce skills, American firms have a problem. Human-resource management is not traditionally seen as central to the competitive survival of the firm in the United States. Skill acquisition is considered an individual responsibility. Labour is simply another factor of production to be hired--rented at the lowest possible cost--much as one buys materials or equipment. The lack of importance attached to human-resource management can be seen in the corporate management. In an American firm the chief financial officer is almost always second in command. The post of head of human-resource management is usually a specialized job, off at the edge of the corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer(CEO). By way of contrast, in Japan the head of human-resource management is central--usually the second most important executive, after the CEO, in the firm's hierarchy. While American firms often talk about the vast amounts spent on training their work force, in fact they invest less in the skills of their employees than do either Japanese or German firms. The money they do invest is also more highly concentrated on professional and managerial employees. And the limited investments that are made in training workers are also much more narrowly focused on the specific skills necessary to do the next job rather than on the basic background skills that make it possible to absorb new technologies. As a result, problems arise when new breakthrough technologies arrive. If American workers, for example, take much longer to learn how to operate new flexible manufacturing stations than workers on Germany (as they do), the effective cost of those stations is lower in Germany than it is in the United States. More time is required before equipment is up and running in production, and the need for extensive retraining generates costs and creates bottlenecks that limit the speed with which new equipment can be used. The result is a slower pace of technological change, and in the end the skills of the bottom half of the population affect the wages of the top half. If the bottom half can't effectively make the processes that have to be operated, the management and professional jobs that go with these processes will disappear. What is the position of the head of human-resource management in an American firm?
Choices:
A. He is one of the most important executives in the firm.
B. His post is likely to disappear when new technologies are introduced.
C. He is directly under the chief financial executive.
D. He has no say in making important decisions in the firm.

Question:
American author Mark Twain once noted that "life would be surely happier if we could only be born at the age of 80 and gradually approach 18." Twain's words were only one of many complaints about aging. The ancient Greek poet Homer called old age "hateful", and William Shakespeare termed it "terrible winter". Alexander the Great, who conquered most of the known world before he died around 323 B.C., may have been looking for a river that healed the of age. During the 12th century A.D., a king called Prester John ruled a land that had a river of gold and a fountain of youth. But the name linked most closely to the search for a fountain of youth is 16th-century Spanish explorer Juan Ponce de Leon. He thought it would be found in Florida. In St. Augustine, the oldest city in the U.S., there's a tourist attraction. It is said to be the fountain of youth that Ponce de Leon discovered soon after he arrived in what is now Florida in 1513. However, elderly visitors who drink the spring's water don't turn into teenagers. But the tale of the search for a fountain of youth is so appealing that it survives anyway, says Ryan K. Smith, a professor of history. "People are more attracted by the story of looking and not finding than they are by the idea that the fountain might be out there somewhere." Still, a few grains of truth have helped to support . Kathleen Deagan, a professor of archaeology, says a graveyard and the remains of a Spanish mission dating back to St. Augustine's founding in 1565 have been discovered near the so-called fountain of youth. Michelle Reyna, a spokesperson for the Fountain of Youth Archaeological Park in St. Augustine, says the fountain has been a tourist attraction since at least 1901 and may have been attracting visitors since 1860. Which of the following is TRUE according to the passage _ ?
Choices:
A. The underlined words "the story" refers to Alexander the Great ruling a land that had a river of gold and a fountain of youth.
B. Augustine, which is the oldest city in the U.S, lies in Florida.
C. Some elderly visitors find themselves younger after drinking the water from the fountain of youth.

Question:
The Toltec---as they were now called ---began to know great abundance and enjoy the generous gifts of the land, as had been foretold by Quetzalcoatl. "He has great powers.He has made us rich.We have not known hunger since he arrived.Where he places his eyes and hands,everything is abundance and beauty." They were happy, they were proud. At that time they all still worked at the jobs Quetzalcoatl assigned to them. Tula grew. People came from far away to admire its growth. Many asked permission to settle down and enjoy its abundance,which was distributed according to the needs of the people. Topiltzin was in charge of distributing the riches,under the orders of Quetzalcoatl, so that no one would want. They were all content because they all had more than they had ever had. Many worked.They were busy all day. Quetzalcoatl had spent six years among the Toltecs. The house for the heart of the people was almost finished and the granaries full when he decided. "There is prosperity and abundance in all the land.Let us extend it beyond the mountains.We shall go to the land of the Chichimecs.It is time to take my mission to them. I shall make them better,I shall make them live together,I shall gather them in towns,I shall teach them to till the land and to build their homes." "Let us leave them in their land as they are now ,"Topiltzin argued,"They are savages ;their life is violent and disorderly.They move freely,like the wind in the mountains and the plains,with nothing to keep them.Leave them where they are.There is much that we must do in our own land. "I do not belong to this land alone.They are all my brothers,I am to give all of them, I shall look for them. I shall take the gods of Tula to them,"Quetzalcoatl said. "Think carefully about what we shall do.You do not know them.They do not understand words. They are like savage animals,like jaguars," Topiltzin insisted. "I shall go,"said Quetzalcoatl."My life must be accomplished.This time you will not accompany me because you do not have the will to go.I shall leave soon with some of my followers." "Do not go with so few people! I shall accompany you with skillful warriors who are used to killing Chichimecs and avoiding their traps." Topiltzin insisted. "I am not going there with violence. I shall go to them as I came here,to take them the gifts of life and the doctrine of sin and redemption ." "You have not spoken of sin and redemption for a long time," Tattle remarked. He had been listening attentively to the dialogue,and was then close to seventeen years of age."You have not come near the Tree you planted in the square in a long time.The Tree has no shoots,it has not grown,it looks sad and lonely." "During this time,Tattle,I have often thought of it.There was confusion in my spirit.Now the Tree orders me to spread good in other lands,to make other brothers happy. It will soon have shoots." This reading passages is most probably an account of _ .

A. history

Question:
Climate change is making it harder than usual for scientists to figure out what the future will bring and what impact weather changes will have on society and the economy. An upsurge of severe weather events has already destroyed homes, businesses and lives. Some fairly simple changes may reduce the toll. In a laboratory test, a house built with conventional techniques is falling apart in hurricane-force winds. The survivor has stronger shingles, thicker roof boards, and metal straps holding floors together. Wind tunnel tests were done by the Insurance Institute for Business & Home Safety. It says stronger construction costs a little more, but holds up much better to extreme weather. The growing number of unusually strong storms, like Typhoon Haiyan, has convinced the Chairman of the U. S. Senate Homeland Security Committee, Tom Carper, that extreme weather is the "new _ )." "Extreme weather events have increased in frequency over the past 50 years and are expected to become even more common, more intense, and more costly," said Carper. Hurricane Sandy hit beachfront businesses along the U.S. East Coast, including Carper's home state. Insurance companies had to pay out huge claims. To limit such losses, the insurance industry can raise premiums for businesses in vulnerable locations and offer discounts to clients who make their buildings more resilient with upgraded construction techniques. Managing risks is the job of insurance brokers like Kevin Connelly of the Graham Company, who spoke to VOA via Skype. "We are either going to price your insurance at a huge markup, or we are not going to write (sell it) it at all, which is just as bad obviously," said Connelly. Drought is another suspected consequence of climate change, and dry ground means more wildfires in California. Current mathematical models of climate change do a poor job of predicting the economic impact of drought and other weather events, says Massachusetts Institute of Technology Professor Robert Pindyck, who spoke via Skype. "I think all we can do, taking all of that into account, is come up with some very rough numbers, very rough estimates, "said Pindyck. "Consensus estimates that maybe experts provide, that give us a view of what would the catastrophic outcome look like if we don't do anything?" To help deal with this serious problem, Pindyck says policymakers should take actions such as imposing a tax on carbon dioxide emissions. A carbon tax would encourage companies and families to use less energy and generate fewer of the gases thought to be driving changes in the climate. But other analysts say it is unlikely a new tax will get approval in the U.S. Congress any time soon. In a laboratory test , what kind of houses can stay up?
Choices:
A. a house built with conventional techniques
B. A house with stronger shingles
C. A house with thinner roof boards
D. a house with metal floors .

Question:
In Jewish history, King Solomon is considered to be the wisest man who ever lived. There are many stories about the wisdom of King Solomon. Here's one. One day two women came before the King. They carried with them a little baby, which was set down on the floor, at the foot of Solomon's throne. One of the women said "Five days ago I gave birth to a child. This woman and I live in the same house, and three days later she also gave birth, but that same night her child died, and at midnight she arose and, while I was sleeping, took my son away from me, and laid her dead child in its place. When I awoke in the morning I thought at first that my son was dead, until I realized that it was not my child." "No," interrupted the second woman, "she is lying, my lord, she is lying! The living child is mine and the dead is hers!" "No," cried the first woman, wildly. "No, the dead child is yours, and the living child is mine." King Solomon raised his hand for silence. "One of you says 'my child lives and yours is dead ', and the other says 'your child is dead and my child lives': there is a simple way to resolve the matter. Bring me a sword." A sword was brought, and the crowd waited to see what the King would do. "Very well," he said, "cut the child in half, and give them each half." The first woman turned pale. She said in a trembling voice. "Give her the child. I beg you, do not kill it." But the other woman's face remained hard. "Let it be neither mine nor yours," she said, "divide it as the King has ordered." Then Solomon arose, and pointed to the first woman. "The child belongs to her," he said. "Give her the child, and do not kill it. She is its mother." Word of this judgment spread throughout Israel, and people marveled at the wisdom of the King. The lesson of this story is rather simple. It is easy to tell the people who really care: they are willing to give up their half in order to keep the whole alive. In short, sometimes insisting on getting your fair share is still a losing strategy. The other women's face remained hard because_.
Choices:
A. she thought it was fair to cut the baby in half
B. she was very sad.
C. it was not her own baby

Question:
"I was only thirteen when four of my team members and I were chosen by my swim coach to train with the Chinese National Team. The following piece shows how that experience has influenced me." The night before I left for China, my mother called me into her room. I entered not knowing what to expect. I sat down at the end of her very neatly-made bed, opposite the bedroom table on which she kept a Ming-style vase illustrated in great detail. She told me that my great-grandmother was still living in the surroundings of Beijing. Her name was Ren Li Ling and she was 97 years old. This was the first time I had ever heard of her. The dragon on the vase snaked through the flowers and vines as my mother said, "Pu Pu, look at me. You need to hear this so that when you go to China you will understand. You must keep this knowledge in your heart." She told me a story about my grandfather, Ren Li Ling's son, who left Beijing to go to college in Taiwan. She told me how the Chinese civil war kept him away from his mother for fifty years, so neither of them even knew that the other was alive. No one from Taiwan could visit, write, or call anyone in mainland. All lines of communication were cut off. She told me of my grandfather's devotion to his own children, and how difficult it was for him to send his daughter to America for her education, fearing that same separation. He gave my mother all that he could give -- nineteen years of love and fifty years of savings. I learned how my mother, through means only available in this country, would finally be able to unite my great-grandmother with my grandfather again. The dragon curled around the vase, connecting the separate vines. For a fleeting second, I felt it was present in my mother's room. It was all very strange, yet very clear. I began to understand that this trip to China was not just for me; it was for my mother, and her father, and his mother. Now, I had not only a future, but more significantly, a past. I saw the world with new eyes. And so I went to China and met my great-grandmother. My great-aunt picked me up at the training center, and we rode in a taxi through the crowded city. The noise of the taxi and the city united into a deep roar. We finally stopped in front of a narrow street lined on either side with small one-level houses. As we made our way to a house like all the others, I drew the stares of many people in the street. My great-aunt led me through a rotting doorway into a room with a furnace , table, and a rocking chair where an old woman wearing gloves sat facing the doorway, covered with a worn brown blanket. I walked over and immediately embraced this frail woman as if I had known her all my life. My limited, broken Chinese wasn't up to expressing my complicated feelings. And even though I couldn't completely understand what she was saying in her thick Beijing accent, I knew -- the same way I knew what my mother had been trying to tell me before I left. Her joy shone through her toothless smile. She wouldn't let go of my hand. I haltingly asked her how she had managed to live such a long life. She answered in words I will never forget, "Hope has kept me alive. I have lived this long because I wanted to see my son before I died." My fellow team members must have wondered how two people separated by three generations could be so close. Before this trip, I would have wondered the same thing. And even now, I can't quite explain it. We were as different as two people can be; some 85 years and 8,000 miles apart. We came from two entirely different cultures; yet we were connected by a common heritage . I stayed for dinner which was cooked in a black iron wok over the furnace. The meal was lavish , prepared in my honor. As I began to eat, with my great-grandmother beside me, I felt the dragon was present. But this time, the feeling didn't pass; the dragon had become a part of me. My great-grandmother passed away last year at the age of 100. With her highest hopes and wildest dreams fulfilled, I know she died happy. The dragon is mentioned several times in the passage because _ .
Choices:
A. the vase with the dragon on it is very valuable and beautiful

Question:
Dogs can also go to school to learn how to help people who cannot hear. If a person cannot hear, we say he or she is deaf. Dogs who help deaf people must learn many different sounds. Then they must be able to show the deaf person what is making the sound. When they hear a visitor at the door, dogs learn to walk to the deaf person and then walk to the door. And if a telephone rings, they walk to the deaf man or woman and then walk to the telephone. These dogs can also help deaf mothers. If a baby is crying in another room, dogs walk to the mother and then to the baby. These dogs wear a yellow coat to show that they are special dogs that are helping a deaf person. There have been many times when these dogs have saved a life. You may see in a newspaper that a dog heard a fire alarm and lay down near the deaf person's feet. That is the sign for danger. The person knows that something is wrong and can go away from the fire. Special dogs can also help people who are disabled in various ways. For example, dogs can pull off their gloves or socks! Think how difficult your life would be if you were blind, deaf or disabled! But if you had a special dog like this to help you, your life would be much easier. Which of the following statements is TRUE?
Choices:
A. Special dogs can do what people cannot do.
B. Special dogs can only help people who are deaf.
C. Special dogs can help people in every part of their life.

Question:
Have you ever seen snow? Many people in the world have not. Some countries never have snow; some have only a little on the tops of very high mountains. In the north of England, there is quite a lot of snow every winter, but in the south of England, there is usually little. When a student from a warm country comes to England in autumn for the first time, he feels cold at first. There are often dark clouds, grey sky and cold rain in England in autumn, and most students from warm countries do not like this. But snow is different. Though it is cold, it is also beautiful. Perhaps, after several dark mornings, the student wakes up one day, and there is a lot of light in his room. He thinks "Is it so late?" and jumps out of bed. But no, it is not very late. He looks out of the window and there is the snow on the ground and on the houses and everywhere. The light of his room comes from clean, beautiful snow.

Question:
Everyone takes drugs.Sometimes a drug might be called a herb but the effect is the same.Drugs and herbs can make life better for they are used to improve health.From the simplest headache to a cure for cancer, people believe that certain drugs can help them.But there is danger if the drugs are not used in a proper way. American teenagers sometimes use certain drugs to feel good.They call this "getting high".The problem is that once a young man or a young woman has the feeling of"getting high",they want to do it often.If school is boring or too hard,students might get depressed and a drug or herb might help them feel better.If the student takes too much of a drug,the body may change in a wrong way such as a confused mind,poor sight,a headache,and an uncomfortable stomach. Schools now have D.A.R.E.program which means Drug Abuse Resistance Education.This program was started so that young students from age 10 to 18 might understand how a drug affects their bodies.The main point of the program is education.Once a student understands certain drugs can cause ill health,he will know he should not use them. Education is the key to good nutrition as well.If a student eats correctly,he or she will be full of energy which leads to good study habits and good grades.Poor nutrition may cause the need for more sleep and poor concentration.Proper food is similar to the proper use of drugs.Both allow a healthy body to grow while misuse of them prevents a person from developing normally. Drugs can make life better and improve health when people_.

Question:
Vanessa Brown, a senior lecturer of art at Nottingham University, explores the cultural and psychological relation between sunglasses and our modern idea of "cool." Her research has uncovered about why most of us look better in shades. Because they really make your misshapen face look better. Put on a pair of sunglasses, and an instant beauty as a result of balance! The dark lenses cover up any unbalanced oddities around your eyes, and research on facial attractiveness shows a clear link between balance and our sense of beauty. Because of mystery. Many of the quick judgments we form about people come from looking in the eyes; shade yours, and you're instantly a more attractive presence. Eye contact helps us form judgments about someone's intelligence, confidence, and sincerity and sunglasses keep us literally in the dark about forming those perceptions. And it works both ways, because the wearer of the sunglasses feels more mysterious, too. Because of their historical link with sharpness and attraction. We take their existence for granted today, but sunglasses are relatively modern, Brown said. Sales started to pick up in the 1920s, but they didn't become commonplace until about two decades after that. The way sunglasses were most used prior to their commercialization helps explain their inside coolness, Brown said, because in their early days sunglasses were primarily used during risky water and snow sports, which made them seem "daring and totally modern." Soon after that, Hollywood stars of the 1950s and 1960s started wearing sunglasses to defend themselves from being recognized by the public or bothered by paparazzi , whose flashbulbs would often explode violently, Brown said. Anyhow, movie stars' adoption of them strengthened a sense of romance. Also--and this is more from my own personal research than Brown's--hang-overs. They're really great for hiding hang-overs. The writer believes that Hollywood stars prefer to wear sunglasses _ .

Question:
On behalf of the Electric Reliability Council of Texas (ERCOT), I would like to take this opportunity to thank you for conserving electricity during this period of continuous hot, dry weather in Texas. At ERCOT, we have been working around the clock to keep the electricity flowing, making sure you have the resources you need to stay productive and well this summer. While we are always charged with making sure you have adequate electricity, this summer has caused a particularly serious challenge to the electric grid . Because the heat has been sustained over the entire state with little or no rain or cloud cover, the strain on the electric grid has been greater than ever before. In Dallas and Austin, we are beating all-time records for triple-digit heat. We have hit three all-time demand peaks in the last two weeks alone, meaning we've used more electricity on three days this summer than on any other day in the history of ERCOT, which covers most of Texas. Additionally, Texas is experiencing economic and population growth while much of the rest of the country is not. All of these factors are contributing to very high energy usage this summer. As you probably read in your newspaper or saw on the news, ERCOT has issued appeals for conservation across the state this August. We have encouraged businesses and residential customers to help us save electricity between the critical hours of 3 and 7 p.m. For instance, turning off unnecessary lights, appliances and electronic equipment can help conditions significantly. Conservation efforts help us avoid statewide rotating outages and keep your lights on and air-conditioners running. Conservation not only keeps power and cool air flowing to every citizen, it ensures that uninterrupted power flows to critical care customers, who are easily harmed in the extreme heat. While ERCOT has not called for rotating outages this summer, it is important to remember that we only carry out these orderly, temporary outages to prevent a catastrophic collapse of the electric grid. As you may remember from the Northeast blackout a few years ago, once a grid failure occurs, it can take days to restore power to all consumers. Your conservation efforts help us prevent this from happening. While ERCOT always carries reserves, our power supply is not unlimited. With your help and conservation efforts, though, we can keep residents and businesses healthy and productive this summer. We can know from the passage that _ .
Choices:
A. a grid failure occurred in the Northeast several years ago
B. the residents of Texas don't like hot, dry weather
C. more electricity has been consumed this summer than in any other summer
D. it takes weeks for the grid to return to normal once it fails

Question:
From the moment that an animal is born it has to make decisions . It has to decide which of the things around it are for eating , and which are to be avoided ; when to attack and when to run away . The animal is , in fact , playing a very dangerous game with its environment , a game in which it must make decision--a matter of life or death . Animals' ability to act reasonably is believed to come partly from what we may call "genetic learning" , which is different from the individual learning that an animal does in the course of its own lifetime . Genetic learning is learning by a species --animals of the same kind--as a whole , and it is achieved by selection of those members of each generation that happen to act in the right way . However , the role of genetic learning depends upon how similar the future environment is to the past . The more important individual experience is likely to be , the less important is genetic learning as a means of getting over the problems of the survival game . Because most animals live in ever changing evironments from one generation to the next , it is not surprising to find that very few species indeed depend wholly upon genetic learning . In the great majority of animals , their particular ways of acting in a new environment are a compound of individual experience added to the action patterns animals are born with .That is why animals can survive . When the environment doesn't change much ,_.
Choices:
A. animals cannot act in a right way
B. genetic learning is less important for animals
C. individual learning plays a less important role

Question:
"OK,"I said to my daughter as she bent over her afternoon bowl of rice."What's going on with you and your friend J.?" J.is the leader of a group of third-graders at her camp-- a position Lucy herself occupied the previous summer. _ and every day at snack time, she tells me all about it, while I offer the unhelpful advice all summer long. "She's fond of giving orders, "Lucy complained."She's turning everyone against me.She's mean.And she's fat." "Excuse me," I said, struggling for calm."What did you just said?" "She's fat." Lucy mumbled ."We're going upstairs," I said, my voice cold."We're going to discuss this." And up we went.I'd spent the nine years since her birth getting ready for this day, the day we'd have the conversation about this horrible word.I knew exactly what to say to the girl on the receiving end of the teasing, but in all of my imaginings, it never once occurred to me that my daughter would be the one who used the F word-Fat. My daughter sat on her bed, and I sat beside her."How would you feel if someone made fun of you for something that wasn't your fault?" I began."She could stop eating so much," Lucy mumbled, mouthing the simple advice a thousand doctors have given overweight women for years. "It's not always that easy," I said ."Everyone's different in terms of how they treat food." Lucy looked at me, waiting for me to go on.I opened my mouth, then closed it.Should I tell her that, in teasing a woman's weight, she's joined the long tradition of critics? Should I tell her I didn't cry when someone posted my picture and commented , "I'm sorry, but aren't authors who write books marketed to young women supposed to be pretty?" Does she need to know, now, that life isn't fair ? I feel her eyes on me, waiting for an answer I don't have.Words are my tools.Stories are my job.It's possible she'll remember what I say forever, and I have no idea what to say. So I tell her the only thing I can come up with that is absolutely true.I say to my daughter, "I love you, and there is nothing you could ever do to make me not love you.But I'm disappointed in you right now.There are plenty of reasons for not liking someone.What she looks like isn't one of them." Lucy nods, tears on her cheeks."I won't say that again," she tells me, and I pull her close, pressing my nose against her hair.As we sit there together, I pray for her to be smart and strong.I pray for her to find friends, work she loves, a partner who loves her.And still, always, I pray that she will never struggle as I've struggled, that weight will never be her cross to bear.She may not be able to use the word in our home, but I can use in my head.I pray that she will never get fat. The author's attitude towards her daughter can be best described as _ .

Question:
Old-Fashioned Play--For Pay Kids !Come have a ball! Or 60,000 of them! There's a new type of business franchise that is appearing in shopping malls and neighborhoods acrossprefix = st1 /Americaoffering pay-per-use indoor playgrounds ,which feature toys ,games ,supervised fun and a workout that doesn't break the family bank. As public playgrounds grow increasingly worn and dirty, the for-profit centers offer clean, safe supervised activity as well as a variety of challenging exercises to develop youngsters' physical fitness, usually for a fee of around 5$ an hour. "Playgrounds are dirty ,not supervised," says Dick Guggenheimer ,owner of the two-month-old Discovery Zone in Yonkers, N.Y., part of Kansas City-based chain, "We are indoors; we are padded ;parents can feel their child is safe". In order to satisfy the need of two-earner families ,the new franchise stayed open in the evenings ,long after traditional public playgrounds have grown dark and unusable .However these new playgrounds are not meant to be day-care centers .Parents are expected go stay and play with their kids rather than drop them off. But several also provide high-tech baby-sitting services. At some of the Discovery Zones, parents can register their children in special supervised programs, then leave them and slip away for a couple of hours to enjoy a movie or dinner. If there is a problem ,Mom and Dad are called. The most fun of all, though, is getting to do what parents used to do in the days before two-earner families and two-hour commutes; play with their kids. That ,at least ,is old-fashioned, even at per-hour rates. What does the writer mean by saying "old-fashioned"?
Choices:
A. The so-called new playground is outdated.
B. The new playground is also enjoyed by old people.
C. The new playground is actually enjoyed by parents.

Question:
There are many people who could be Olympic Champions. I'd estimate five million people could have beaten me in the pole-vault on the years when I won it, at least five million. Men were stronger, bigger, and faster than I could have done it, but they never picked up a pole, never made the efforts to vault their legs off the ground to try to get over the bar. Greatness is all around us. It's easy to be great because great people will help you. What was fantastic about all the conventions I went to was that the greatest in the business would come and share their ideas, their methods and their techniques with everyone else. I have seen the greatest salesmen showing young salesmen exactly how they did it. They didn't hold back. I have also found it true in the world of sports. I'll never forget the time I was trying to break Dutch Warmer Dam's record. I was about a foot below his record, so I called him on the phone. I said, "Dutch, can you help me? I seem to have _ . I can't get any higher." He said, "Sure, Bob, come on up to visit me and I'll give you all I got." I spent three days with the master, the greatest pole-vaulter in the world. For three days, Dutch gave me everything he'd seen. There were things that I was doing wrong and he corrected them. To make a long story short, I went up eight inches. That great guy gave me the best that he had. Great people will share. Great people will tell you their secrets. Look for them, call them on the phone or buy their books. Go where they are, get around them and talk to them. It is easy to be great when you get around great people. What would be the best title for the passage?

Question:
A lot of grown-ups worry that spending too much time playing video games isn't good for a kid's health. Now some doctors have noticed that kids who bring their hand-held game players to the hospital seem less worried about being there. These patients also seem to experience less pain when they are concentrating on a superhero adventure or a car race. At the Johns Hopkins Children's Center in Maryland, young patients are finding hospital visits easier to deal with, thanks to a test program called the Hospital-based On-line Pediatric Environment (HOPE). Patients in HOPE have a life-threatening condition where their kidneys no longer filter wastes from their blood. To get their blood cleaned, these kids must be hooked up to dialysis machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play online sports, racing, and adventure games with each other. Eventually they will be able to connect with kids in other hospitals who are suffering from the same problem. "We want to use the power of the Internet to bring together kids who feel that they are separated by their illness, and let them know that they are not alone," said Arun Mathews, the doctor who heads the program. He loves video games himself and got the idea to connect kids all over the country. Many researchers elsewhere are testing video game programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, who was struggling with cancer helped to design a video game where players get rid of cancer cells. That's all great news, because doctors already know that reducing pain and worry helps patients heal faster. Which of the following plays the most important role in the HOPE project?
Choices:
A. Music.
B. The Internet.
C. Novels.
D. Films.

Question:
Johnny the Explorer Johnny was three when he ran away from home for the first time. Somebody left the garden gate open. Johnny wandered out, crossed some fields, and two hours later, and arrived in the next village. He was just able to give his name and address. By the time he was seven, Johnny used to vanish from home two to three times a year. Sometimes he covered quite long distances on foot. On other occasions he got on a bus or even a train, and simply sat there until someone asked for his ticket. Generally the police brought him home. "Why do you do it?" they used to ask. "You aren't unhappy at home, are you? .... ""Of course not," Johnny replied." Then why?" "I just like seeing places," Johnny told them. Johnny continued to "see places" although everyone tried to stop him. His parents used to watch him closely, and so did his teachers; but sooner or later Johnny managed to slip away. As he grew older, his favorite trick was to hide on a long distance truck. Sometimes he used to travel hundreds of miles before anyone discovered him. It is hardly surprising that eventually Johnny managed to get on board a plane. He was twelve at the time. It was a cargo plane and, a few hours later, Johnny found himself in Cairo. How did he get on board? No one knows! According to Johnny himself, it was easy: he just went into the airport, walked along some corridors and got on board the nearest plane. In spite of all this, Johnny did well at school. He enjoyed maths and languages and, perhaps not surprisingly, he was especially good at geography. "What do you want to be when you grow up?" his teachers asked him. Johnny did not take long to answer that question. "An explorer!" he answered. "But it's difficult to become an explorer in this modern age." they tried to tell him, But it was no use: Johnny knew what he wanted! Just before he left school, Johnny saw a notice in one of the daily papers. An expedition was about to go to Brazil to travel up the Amazon River. There were vacancies(,) for three young people "willing to work hard and with a sense of adventure". Johnny applied, and, one month later, he was on his way to Brazil. People around Johnny _ .

Young Jack moved to a new house. When entering his new bedroom, he saw that it was full of toys but it was tidy. That day he played all he liked, but went to bed without tidying up. The next morning, when Jack got up, he found all the toys had been put back in their proper places. He was sure that no one had entered his bedroom, but the boy didn't pay much attention to it. The exact same thing happened that day, and the next day. But on the fourth day when he went to get his favourite toy, the toy jumped out of his hands and said, "I don't want to play with you!" Jack felt surprised, but the same happened with every toy he touched. Finally, one toy said to him: "We don't want to play with you. You always leave us so far away from our proper places.

Question:
It was on the afternoon of the day of Christmas Eve, and I was in Mrs. Prothero's garden, waiting for cats, with her son Jim. It was snowing. Patient and cold, our hands wrapped in socks, we waited to snowball the cats. The wise cats never appeared. We were so still in the snows that we never heard Mrs. Prothero's first cry from the bottom of the garden. Or, if we heard it at all, it was, to us, like the cry of the neighbor's Polar cat. But soon the voice grew louder. " Fire!" cried Mrs. Prothero. And we ran down the garden, with the snowballs in our arms, towards the house; and smoke, indeed, was pouring out of the dining room. This was better than all the cats in Wales standing on the wall in a row. We loaded with snowballs, stopped at the open door of the smoke-filled room. Something was burning all right; perhaps it was Mr. Prothero, who always slept there after midday dinner with a newspaper over his face; but he was standing in the middle of the room, saying, " A fine Christmas!" There was no fire to be seen, only clouds of smoke and Mr. Prothero standing in the middle of them, waving his slipper as though he were conducting. " Do something," he said. And we throw all our snowballs into the smoke---I think we missed Mr. Porthero---and ran out of the house. " Let's call the police," Jim said. "And Ernie Jenkins, he likes fires." But we only called the fire-brigade, and soon the fire-engine came. Mr. Porthero gout out just in time before they turned the hose on. When the boys saw smoke pouring out of the dining room, _ .

Question:
Just as the stock market rises and falls in response to what people are willing to put their money behind, we have inside ourselves an inner economy that rises and falls in response to our beliefs about what is possible. Sometimes the degree to which we are willing to challenge our belief systems determines the success of our inner economy. For example, imagine that your family of origin had a belief that musical talent was not something they possessed. As a member of that group, you would likely inherit that same belief about yourself. As a result, even if you had a great desire to create music, you might be hesitant to really get behind yourself, fearing that your investment would not pay off. Even if you had the courage to follow your passion, your inner belief that you are not inherently talented would probably be a major drawback to investing your energy in your dream. On the other hand, if you found a way to release that negative belief, a great flood of energy would pour forth, greatly increasing the likelihood of your success. How much energy we are willing to invest in the various ideas, dreams, and visions we carry within is like the money people are, or are not, willing to invest in the various products available for trade on the stock market. And in both cases, belief plays a key role in determining how willing we are to get behind something. One way to open up the possibility for greater success in our inner economies is to understand that belief is not the reliable guide we sometimes think. There are other more reliable things of success that we can put our faith in, such as passion, feeling, and sense. Some of the most successful investors in the stock market are the ones that go against the grain (to be something that one does not like doing), trusting their sense over the common opinion held by common people about what will work. In the same way, we can learn to trust our heart's desires and our sense to guide us, questioning any beliefs that stand in the way of our ability to fully invest in ourselves. As we take out energy from limiting ideas about what is possible, we free up the resources that have the power to make our inner economy prosper. The purpose of the author is_.
Choices:
A. to teach us a lesson
B. to give us some useful suggestions
C. to tell us that our belief is not reliable
D. to encourage us to invest in the stock market

Question:
Across the planet there are millions of people who engage in some type of meditation, the practice of concentrating and clearing the mind to bring the body into a state of peace, at least a semi-regular basis. For some, particularly among practitioners of Eastern religions such as Buddhism and Hinduism, this is _ of their religious practice. For others, particularly in Western cultures, meditation tends to be a response to stress. With the world economy approaching meltdown and people worried about their job or their ability to keep their home, it's a way for people to attain a state of peace of mind and well-being. For those interested in taking up the practice, instruction in meditation for beginners can be found in literally thousands of sources. One of the most popular styles of mediation in the West, with classes offered in most major cities, is called Transcendental Meditation. TM, as it is known among its practitioners, first came to worldwide attention when the Beatles began practicing it in 1967. For direct, guided, personal instruction in meditation for the beginner, TM may be the hallmark. Part of the confusion about how to practice meditation effectively is due to the fact that there are literally hundreds of techniques championed by various groups and individuals. As a general principle, it might be said that all meditation techniques seek to have the practitioner attain a state of consciousness that is different to our ordinary state of awareness. They attempt to train people to clear their minds and achieve a sense of inner peace. It sounds simple enough, but of the huge number of people experiment with meditation, very few are able to maintain its practice over the long haul. In most cases, this is due to frustration over the inability to experience any dramatic, instantly recognizable effects. This is quite a sad state of affairs, that so few these days are willing or equipped to persist in something that doesn't provide immediate life-changing results. It reflects a culture in which demands for discipline and sustained effort are considered unnecessary or even unfair. It is no surprise therefore that many people abandon their efforts at meditation before they have a chance to bear fruit. But for anyone who does decide to take up this worthwhile practice, please remember. You must clear your mind, relax and "take it as it comes". Maintain the practice with a sense of discipline and devotion, and eventually benefits of inner peace and calm will be yours. What can we infer about meditation from the passage?
Choices:
A. It has two main types.
B. It is practiced by many famous artists.
C. Its benefits are not immediately obvious.
D. Most people find it a very good way to relax.

Question:
Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet. Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet. What the writer thinks is that _ .

A. schools are still necessary
B. more schools should be built
C. there should be fewer schools
D. more computers are needed in schools

Question:
There are plenty of creams etc on the market that help you look younger, but today, Dr Oz is going to show how some people are actually living longer. "We are going to talk about extreme life extension," he says. "I am talking in details about allowing us to go into our second century of life with the energy that you have when you are a young person." Owing to advances in technology and research on how diet affect the aging process, Dr Oz says it might be possible for some people to live to see their 120th birthdays. There's one man in Oprah's audience who Dr Oz says may become the first man in history to live to be 150 years old. Joe Cordell is one of thousands around the world who believe they've found the key to an extreme long life --- calorie restriction leads to a longer, healthier life. At 59 Joe weighs 130 pounds. He may not look like a person who needs to count calories, but as part of his life extension program, he inspects every mouth of food that passes through his system. Every day for the past seven years, Joe has limited himself to about 1,950 calories. He believes that by eating less and restricting his caloric intake, he will _ a genetic switch that slows the aging process. Joe doesn't take away himself of food. Instead, the then 52-year-old father filled up on natural fruits, vegetables and lean proteins that were packed with necessary vitamins and nutrients. "Whenever you are thinking about calorie restriction, you should continually think about getting the most nutritional amount per calorie," Joe says. In keeping with this principle, Joe starts every morning with three apples...but he only eats the peels. "Most of the fiber is in the peel, and more importantly, most of the nutrients are in the peel," he says. "It is important to eat some nuts with breakfast so that you do take in some fat, some healthy fats," he says. "I think it helps the absorption of the nutrients, and it is very filling." For lunch, Joe usually eats a large salad, loaded with vegetables. At dinnertime, he and his family enjoy lean meat or fish and more vegetables. When Joe started practicing calorie restriction, he weighed 175 pounds. Since then, he has lost 45 pounds, and he says he hasn't had a cold in seven years. Though he is in his "golden years", researchers studying Joe say he has the body of a 20-year-old athlete. According to the passage, the extreme life extension refers to _ .

Question:
According to the Ministry of Health, 260 million Chinese people have chronic diseases, and 85 percent of all deaths in China are caused by such diseases. Among them, cardiovascular disease has bothered more people than any other kind of chronic disease. According to the WHO(World Health Organization), salt consumption , one of the key causes of high blood pressure that can lead to cardiovascular disease, is much higher in China than in other countries. Douglas Bettcher, the director of the WHO's Tobacco Free Initiative, says, "The average Chinese person consumes about 12 to 14 grams (of salt) per day, while the suggestion of the WHO is consumption of less than 5 grams per day. High salt consumption is a major cause of cardiovascular disease and high pressure in China. Changing the way that food is prepared could reduce salt consumption in China. Another major risk factor in China is smoking. Dr Michael O'Leary, a representative of the WHO, says, "We know already that one million deaths in China are related to smoking, This is an enormous number. It means that we are seeing nearly 3000 deaths a day in China, or two deaths every minute, related to smoking. According to O'Leary, about 26 percent of men who die from smoking-related diseases in China die before the age of 60. People who can still contribute a great deal, in other words, are dying too young. China has tried to ban smoking , but more efforts are needed. More than half of chronic diseases are preventable by changing lifestyles and reducing risks. The four key risk factors are: smoking, diets high in fats, salt and sugar, environments that prevent physical activities, and alcohol consumption. These are the areas on which efforts to make changes need to concentrate. According to the WHO, how much salt should a Chinese person consume?
Choices:
A. About 12 to 14 grams per day.
B. Less than 5 grams per day.
C. About 17 to 19 grams per day.
D. About 7 to 9 grams per day.

Question:
"Clean your plate!" and "Be a member of the clean-plate club!" Just about every kid in the US heard this from a parent or grandparent. Often, it's accompanied by an appeal: "Just think about those starving orphans in Africa." Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take too many bites. Instead of "cleaning the plate', perhaps we should save some food for tomorrow. According to news reports, US restaurants are partly to blame for the growing bellies(,). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate (......) quantity with value and most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little. Barbara Rolls, a nutrition professor at Pennsylvania State University, told USA Today that restaurant portion(,) sizes began (or grew) in the 1970s, the same time that the American waistline began to expand . Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling for this too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve portions that are too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions. Seventy percent of those earning at least $150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25,000 want smaller. It's not that working-class Americans don't want to eat healthily. It's just that, "after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck, happy to save a little money for next year's Christmas presents." Why do American restaurants serve large portions?
Choices:
A. Because Americans associate quantity with value.
B. Because Americans have big bellies.
C. Because Americans are good eaters.
D. Because Americans are greedy.

Question:
There are many types of reports. A report is simply an account of something that has happened. The commonest are new reports. We get them in newspapers, over the radio and on television. Sometimes cinemas also show us newsreels . The main purpose of a newspaper is to provide news. If you examine a newspaper closely, you will find that there are all types of news: accidents, floods, fires, wars, fashions, sports, books, etc. The news covers everything that happens to people and their surroundings. Sometimes there are news items which are very amusing. A news report is usually very short, except when it is about something very important, but it contains a lot of information. It is also written in short paragraphs. The first paragraph is, in fact, a summary of the news item. It gives all the necessary information--what, when, where, how and why. The other paragraphs give full details of the subject. There may also be interviews with people. The words actually spoken by them are within inverted commas . Often there are photographs with the news to make it more interesting. According to this passage, the main purpose of a newspaper is to _ .

Question:
Throughout history, rainbows have been a source of mystery and legend. Rainbows are also important symbols in a number of cultures around the world. In the Old Testament of the Bible(<<>> ), for example, God shows Noah a rainbow to let him know that the Flood is over and that he will never destroy the earth again with flooding. When it rains, the color1s that make up white light separate because they bend at different angles when they pass through water. The result is some of the color1s can be seen by the human eyes, as well as some that cannot. Everyone knows that we can sometimes see rainbows on a rainy day. However, you actually have a chance of seeing a rainbow anytime there is light behind you and water in the air in front of you. So, if you want to know what it feels like to have the power of God, get a spray , stand with your back to the sun, and create a rainbow! Which of the following is true about rainbows?
Choices:
A. Rainbows once destroyed the earth in history.
B. Japanese believe the rainbow is made from wild flowers.

Question:
Each year about a quarter of a million Americans study abroad. For many of them, a summer or a semester in a foreign country now involves more than just sitting in classrooms and hanging out with other American students. Instead, they are encouraged and sometimes required to be involved in the local communities they are studying in. "It's ly important that they know something about how people in other parts of the world live and think, and how they behave," says William Finlay, head of the sociology department at the University of Georgia. In 2008, he co-founded a study abroad program with South Africa's Stellenbosch University. It combines traditional academic in-class learning with community involvement. "We've been working with a non-government organization in the township. Our students typically either work with little children in day care centers or work in the library and teach very basic computer skills to young children," says Finlay. The three-week program proved to be an unforgettable experience for Hillary Kinsey. She says, "It was interesting to learn the history of the area and then talk to these people and see what the social dynamics were, and how certain groups felt about other groups." When Hillary Kinsey returned home from South Africa, she and other students in the program established a non-profit group. Kinsey says the group wants to contribute to advancing education and development in South Africa. "One of the purposes of the group is that we hope to raise money and awareness about the situation where those people live and help to promote any sort of educational development that we can, " Kinsey added. While many study abroad programs focus on helping Americans to learn foreign languages, others take a more intensive approach. "In all of our locations, we place students with local roommates," says Mark Lenhart, director of CEF Academic Programs, which sends more than a thousand students to China, Korea and other countries each year. He says American students benefit from such one-on-one interactions, in spite of the challenges they face. Lenhart says, "They have to adjust to the local life. This will enable students to become more employable when they graduate." The purposes of Hillary Kinsey's non-profit group include all of the following, EXCEPT _ .
Choices:
A. learning more about South Africa
B. raising money for local people
C. helping to develop education in South Africa

Question:
The bicycling craze came in when we were just about at the right age to enjoy it. At first even "safety" bicycles were too dangerous and improper for ladies to ride, and they had to have tricycles. My mother had (I believe) the first female tricycle in Cambridge; and I had a little one, and we used to go out for family rides, all together; my father in front on a bicycle, and my poor brother Charles standing miserably on the bar behind my mother. I found it very hard work, pounding away on my hard tyres; a glorious, but not a pleasurable pastime. Then, one day at lunch, my father said he had just seen a new kind of tyre, filled up with air, and he thought it might be a success. And soon after that everyone had bicycles, ladies and all; and bicycling became the smart thing, and the lords and ladies had their pictures in the papers, riding along in the park, in straw hats. My mother must have fallen off her bicycle pretty often, for I remember seeing the most appalling cuts and bruises on her legs. But she never complained, and always kept these accidents to herself. However, the great Mrs. Phillips, our cook, always knew all about them; as indeed she knew practically everything that ever happened. She used to draw us into the servants' hall to tell us privately: "Her Ladyship had a nasty fall yesterday; she cut both her knees and sprained her wrist. But don't let her know I told you." So we never dared say anything. Similar little accidents used to occur when, at the age of nearly seventy, she insisted on learning to drive a car. She never mastered the art of reversing , and was in every way an unconventional and terrifying driver. Mrs. Phillips used then to tell us: "Her Ladyship ran into the back of a milk-cart yesterday; but it wasn't much hurt"; or "A policeman stopped her Ladyship because she was on the wrong side of the road; but she said she didn't know what the white line on the road meant, so he explained and let her go on." Mrs. Phillips must have had an excellent Intelligence Service at her command, for the stories were always true enough. Cycling became popular when _ .

Question:
FOR most people, life without plants is unimaginable. They feed us, clean up our air and brighten up our gardens. But what if someone told you that even our smartphones can benefit from plants? Meet the scientists from the Freiburg University of Mining and Technology in Germany. According to reports from Reuters, they have come up with a way to take the important element germanium from plants. The element was first discovered in Germany (hence the name) and was used to develop the first transistor because it can transport electricity very quickly. Nowadays, silicon-germanium alloy plays an important role in making computers, smartphones and fiber-optic cables . Although germanium can be found in soil around the world, it is difficult to extract . In the traditional process, people take the material after zinc mining or burning coal. But the Freiburg scientists decided to fall back on the natural world. Biology professor Hermann Heilmeier is one of the scientists who are using common plants for this uncommon process. "Different energy crops are being planted, for example, sunflowers, corn ... we want to use them for phytomining. In German we call it 'mining with plants'." Others have used this method in the past with metals like gold and copper . But in their study, the Freiburg scientists brought germanium from the soil into the roots and shoots of the plants, harvested them and then took the element from the plants. The process did not cost too much because germanium can be taken after plants are processed for use as biogas . So many of the costs are already covered in existing biogas plants. However, there is still a lot of work to do before we can all experience the benefits. At the moment germanium can only be harvested in very small amounts, just a few milligrams per liter. Now scientists are working on different plants to improve this. "As is so often the case, industry is still waiting because they want to see everything already working. Then they say, 'We'll have it.' But of course we have to complete the step in between first," said Professor Martin Bertau, head of industrial chemistry at Freiburg University. What can we conclude from the article?
Choices:
A. Germanium can be easily produced during the process of mining zinc or burning coal.
B. Sunflowers and corn are currently the most efficient plants to use when extracting germanium.
C. The process of harvesting germanium from plants isn't costly because after harvesting, the plants can be used for biogas.
D. The new method for extracting germanium that the Freiburg scientists are trying is greener and cheaper than the traditional one.

Question:
There is a Web site called the "World Database of Happiness." It combines and analyzes the results of hundreds of surveys from around the world that have been conducted on life satisfaction. Most of the findings are predictable, but a few are surprising. The database makes it clear that there is not a strong connection between material wealth and general contentment. It is a cliche to say that money can't buy happiness, but the old saying seems to be supported by research. Many people still cling to the belief that gaining riches will be the answer to all their problems, yet they are probably mistaken. Studies have been carried out on people who acquired sudden wealth, such as lottery winners. In most cases, after the initial joy had worn off, people were not left with a sense of lasting happiness. In fact, they tended to revert to the way they felt before they became rich. Previously contented people continue to be contented, while those who were miserable before sink back into misery. If material wealth does not bring happiness, then what does? Perhaps happiness has something to do with where you live. The authorities at the World Database on Happiness have surveyed levels of happiness in different countries. Apparently, people in America, Canada, and Singapore are very happy; people living in India and Russia, not surprisingly, are not happy. Other surveys consistently point to the importance of relationships. Family relationships in particular seem to be the key to long-term contentment. The Web site suggests that falling in love and having children are two of the situations that bring the greatest happiness. Nowadays people look to technology as an alternative source of satisfaction. People increasingly spend more time alone watching TV or surfing the Internet rather than spending time with family. Can technology truly make people happy? It is too difficult to tell, but one thing is sure: If the Web site's research is accurate, time spent with your family is a better investment than time spent making money. Which factor can bring lasting happiness definitely according to the study?
Choices:
A. Sudden wealth.
B. Surfing the Internet.
C. Family relationship.
D. Winning lottery.

Question:
On March 17 there will be an explosion of green colour across the world in celebration of St Patrick's Day. The Irish traditionally wear something coloured green on this day as the colour is connected with Ireland. Another St Patrick's Day tradition is for the non-Irish to make jokes about the Irish. Usually these jokes will be about Irish stupidity or their famous thirst for alcohol, or their reputation for telling tall(untrue) stories. These characteristics are all part of the famous Irish stereotype that Irishman are hot-tempered drinkers, who love to fight and will do anything to avoid a day's work. The real joke, however, is that this negative Irish stereotype still exists. The stereotype might have had some truth back in the 19th century when Irish was poverty-stricken and starving. Many Irish moved to the United States to escape famine , but there they had to compete, occasionally with their fists, for jobs and housing with other immigrant groups. It was on America's streets that the Irish earned their reputation for street fighting. However, it was far from truth today, with the exception of the drinking perhaps. Today, the Irish are admired for their story telling gifts and musical talents. It is no accident that several of the greatest writers of the 20th century were Irish. Or that many of today's most popular music groups such as singer Enya and rock band U2, are Irish born and growing. Lonely Planet readers even ranked Ireland as the friendliest country in the world. However, one bit of the Irish stereotype is true, their love for drink. Drinking in Ireland is a job, but it's not necessarily something to criticize. It was the Irish after all who created one of the world's best-loved beers, Guinness. Which of the following statements does NOT belong to the Irish stereotype?

Question:
Maybe it is true that we do not know what we have got until we lose it, but it is also true that we do not know what we have been missing until it arrives. It takes an hour to like someone, and a day to love someone, but it takes a lifetime to forget someone. Giving someone all your love is never an assurance that they will love you back. Do not expect love in return; but if it does not, be content it has grown in yours. Do not rely on one's appearance; it can trick you. Do not rely on wealth; even that fades away. Rely on someone who makes you smile, because it takes only a smile to make a dark day seem bright. There are moments in life when you miss someone so much that you just want to pick them from your dreams and hug them. Dream what you want to dream, go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do. The brightest future will always be based on a forgotten past. You cannot go on well in life until you let your past failures and heartaches go off. May you have enough happiness to make you sweet, enough trials to make you strong, enough sorrow to keep you human, enough hope to make you happy. The happiest of people do not necessarily have the best of everything; they just make the most of everything that comes along their way. Happiness waits for those who cry, those appreciate the importance of people who have touched their lives. Always put yourself in others' shoes. If you feel that it hurts you, it probably hurts the other person, too. When you were born , you were crying and everyone around you was smiling . Live your life so that when you die , you are the one who is smiling and everyone around you is crying . Which of the following statements is true according to the passage?
Choices:
A. If you give someone your love, you are sure to receive love in return.
B. We often don't know what we have lost until it happens someday.

Question:
The Erie Canal was the first important national waterway built in the US. It crossed New York from Buffalo on Lake Erie Troy to Albany on the Hudson River. It joined the Great Lakes with the Atlantic Ocean. The canal served as a route over which industrial goods could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation's largest city. The building of the canal was paid for entirely by the state of New York. It cost $ 7 143 789, but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges were stopped, the state collected $121 461 891. For a hundred years before the Erie was built, people had been talking about a canal which could join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. Those who were against the canal laughingly called it "Clinton's Ditch ". Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful. Clinton became governor of New York in 1817, and shortly afterwards, on July 4, 1817, broke ground for the canal in Rome, N.Y. The first part of the canal was completed in 1820. As the canal grew, towns along its course developed fast. The length of the canal is 363 miles. We can see that the Erie Canal _ .

Have you heard of the following places on Earth that look completely alien? Waiotapu, New Zealand Steam and gases rising through the pool create bubbles of mud, at the site of what was once a volcano. While Waiotapu is a popular tourist spot, visitors are warned to stay on walkways built by the government for fear that they fall through thin crust surfaces and risk being burned by hot geothermal gases or fluids. Rio Tinto, Spain Rio Tinto is a river in southwestern Spain that originates in the Sierra Morena mountains of Andalusia. It flows generally south - southwest, reaching the Gulf of Cadiz at Huelva. As a possible result of the mining, Rio Tinto is notable for being very acidic (pH 2) and its deep red color1 is due to iron dissolved in the water. The Pinnacles, Australia This stretch of desert landscape in Australia's Nambung National Park boasts thousands of weathered rock projections that rise out of yellow sand hills -- some topped by round roofs, while others form sharp-edged columns. The spires , some of which reach 11 feet in height, are limestone formations sculpted by wind, vegetation, rain, sun and time over millions of years. Kilauea Volcano, Hawaii The closest thing on Earth to a Venusian environment may be the smooth, black basalt formations on Hawaii's Big Island. One of the best examples of a Venus-like volcano is Kilauea Volcano, the youngest and southernmost volcano on the island, and one of the world's most active. Since 1952, there have been more than 34 eruptions at Kilauea, which in Hawaiian tradition is the home of Pele, the volcano goddess. Where should you go if you want to watch an active volcano?

Question:
It was a hot afternoon. I had a quarrel with the airport staff and then was asked to have a drug test .I missed the flight home later because of bad weather. Now my flight home was full and running late. I felt sorry and unlucky. At that moment,I noticed a 5-year-old boy standing by his mother watching me. He left his mother and slowly walked towards me."Great!"I thought sadly,"Now I have to take care of a 5-year-old child. My day is now complete." As he came closer,I found it was my hat that he was after. I wanted to tell him not to touch my things,but I was curious to know what he would do with my hat. With wide eyes,he gently touched my hat. He looked up at me,smiling,but saying nothing. I asked him if he wanted to wear my hat,he excitedly nodded,still smiling. I placed my hat on his head,but it fell down around his ears. He didn't mind and held it up with both hands. He ran to show his mother,then back to me,still smiling. With much respect,he slowly took off my hat with both hands and gave it to me. I put my hat on and gave him an airplane card. Holding the card carefully with both hands,he looked up at me and said,"Mister,you sure are lucky.""Yes,I sure am,"I said. I admired the wisdom of a 5-year-old boy,as I got the last seat on that flight home. What did the writer feel when he watched the boy walking towards him?

Question:
There was once a man called Mr. Flowers, and flowers were his only joy in life. He spent all his free time in one of his four glass-houses and grew flowers of every color, with long and difficult names, for competitions. He tried to grow a rose of a new color to win the silver cup for the Rose of the Year. Mr. Flowers' glass-houses were very near to a middle school. Boys of around thirteen of age were often tempted to throw a stone or two at one of Mr. Flowers' glass-houses. So Mr. Flowers did his best to be in or near his glass-houses at the beginning and end of the school day. But it was not always possible to be on watch at those times. Mr. Flowers had tried in many ways to protect his glass, but nothing that he had done had been useful. He had been to school to report to the headmaster; but this had not done any good. He had tried to drive away the boys that threw stones into his garden; but the boys could run faster than he could, and they laughed at him from far away. He had even picked up all the stones that he could find around his garden, so that the boys would have nothing to throw; but they soon found others. At last Mr. Flowers had a good idea. He put up a large notice made of good, strong wood, some meters away from the glass-houses. On it he had written the words: DO NOT THROW STONES AT THIS NOTICE. After this, Mr. Flowers had no further trouble; the boys were much more tempted to throw stones at the notice than at the glass-houses. Mr. Flowers' good idea was to _ .

B. put up a large notice to cover his glass-houses

Question:
Many everyday American expressions are based on colors. Red is a hot colour. Americans may say they are red hot about something unfair. They are red hot when they are very angry about something. The small hottasting peppers found in many Mexican foods are called red hot for their colour and their fiery taste. Fast loud music is popular with many people. They may say the music is red hot, especially the kind called Dixieland jazz. Pink is a lighter kind of red. People sometimes say they are in the pink when they are in good health. The expression was first used in America at the beginning of the twentieth century. It comes from the fact that many babies are born with nice pink skin that shows that they are in good health. The colour black is often used in expressions. People describe a day on which everything goes wrong as a black day. A blacklist is illegal now. But at one time, some businesses refused to employ people who were on a blacklist for belonging to unpopular organizations. The colour green is natural for trees and grass.

Question:
Most of the time, people wear hats to protect themselves from _ weather conditions. Hats are also worn to show politeness and as signs of social position. But nowadays, hats, especially women's hats, are much more than that. More exactly, hats have changed into fashion and style symbols by many movie stars. What's more, people now consider many different features when choosing even a simple hat. Many designers point out that, when choosing the right hat, it's important to consider the color of your skin as well as your hair, your height, and the shape of your face. First of all, the color of the hat should match the color of your skin and hair. For instance, black hats should be avoided if you are dark skinned. If a purple hat is placed on top of red hair, one will look as attractive as a summer flower. Second, the height of the hat is also an important point. Tall women should not go for hats with tall crowns, just as short women should choose hats with upturned brims to give the look of height. Third, and most importantly, the shape of the face decides the kind of hat one should pick. A small, gentle hat that fits the head looks good on a small face. However, women with big, round faces should choose a different style. As the saying goes, "Fine feathers make fine birds." A good hat can not only help your dress but also support your features, so why not choose the best possible one next time you want to be in public? What is the best title for the article?

A. How to Show Your Social Position.

Question:
Standard English is that variety of English which is usually used in print,and which is normally taught in schools and to non-native speakers learning the language.It is also the variety which is normally spoken by educated people and used in news broadcasts and other similar situations.The difference between standard and non-standard,it should be noted,has nothing in principle to do with differences between formal and informal language:Standard English has informal as well as formal variants. Historically the standard variety of English is based on the London Dialect of English that developed after the Norman Conquest resulted in the removal of the Court from Winchester to London.This dialect became the one preferred by the educated,and it was developed and promoted as a model,or norm,for wider and wider parts of society.It was also the norm that was carried overseas.But not one unaffected by such export.Today,standard English is codified to the degree that the grammar and vocabulary of English are much the same everywhere in the world where English is used:difference among the local standards is really quite minor,so that the Singapore,South Africa,and Irish varieties are really very little different from one another so far as grammar and vocabulary are concerned.Indeed,standard English is so powerful that it puts a tremendous pressure on all local varieties,to the degree that many of the long-established dialects of England have lost much of their vigor and there is much pressure on them to converge towards the standard.This latter situation is not unique to English:it is also in other countries where processes of standardization are under way.But it sometimes creates problems for speakers who try to strike some kind of compromise between local norms and national,even super-national ones. The main topic of the text is
Choices:

Question:
A team of British surgeons has carried out Gaza's first organ transplants for a long-term plan to train local medical staff to perform the operations. Two patients underwent kidney transplants at the Shifa, Gaza's biggest public hospital. The operations were conducted a fortnight ago by a volunteer medical team from the Royal Liverpool hospital. Ziad Matouk, 42, was born with one kidney and was diagnosed with renal failure several years ago. Matouk, whose wife donated one of her kidneys, hopes to return to his job within six months. The couple had sought a transplant in Cairo, but were rejected as unsuitable at a state hospital and could not afford the fee at a private hospital. "We were desperate," said Matouk. The UK-Gaza link-up began about a year ago after Abdelkader Hammad, a doctor at the Royal Liverpool hospital, was contacted by an anaesthetist at the Shifa, who outlined the difficulties the Gaza hospital was facing with dialysis . The Shifa is forced to rely on generators because of power cuts; spare parts for its ageing dialysis machines have been difficult to import; and supplies of consumables are often scarce. After an exploratory trip last April, Hammad---whose family is Palestinian---and three colleagues from Liverpool arrived in Gaza via Egypt last month, bringing specialist equipment. Two patients were selected for surgery. The first, Mohammed Duhair, 42, received a kidney donated by his younger brother in a six-hour operation. Two days later, Matouk received a transplant after his wife, Nadia, 36, was found to be a good match. The surgeon was carried out by the British team, assisted by doctors and nurses from the Shifa. "We are very satisfied with the results," said Sobbi Skaik, head of surgery at the Gaza hospital. Skaik hopes that Gaza medical teams will eventually carry out kidney transplants independently, and that other organ transplants may follow. The Shifa is working with the Gaza ministry of health on a plan to train its doctors, surgeons, nursing staff and laboratory technicians in transplant surgery at the Royal Liverpool. "Funding is a problem," said Hammad. "In the meantime we'll go back as volunteers to Gaza for the next couple of years to do more transplants." The Liverpool team's next visit is scheduled for May. What effect does Gaza's first organ transplants hopes to get?
Choices:
A. Helping poor Gaza people to regain health to make more money.
B. Releasing Gaza hospitals' pressure of lack of professional doctors.
C. Assisting the Royal Liverpool hospital in perfecting their operations.
D. Calling for international attention at Gaza's poor medical service.

Question:
When you watch TV and play video games you make global warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases . This means that every time you use electricity you help make global warming worse! Cars are also making global warming worse. They burn fossil fuels in their engines, and send lots of greenhouse gases into the air. Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let's try one of these top ideas: (1) Try to use less electricity. Turn off lights, your television, and your computer when you've stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV. (2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow. (3) Don't throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots and makes a greenhouse gas called methane .So try to recycle cans, bottles, plastic bags and newspapers. It'll make you feel great! And it'll help the Earth. If we _ , we may make global warming worse.

Question:
The social sciences, as the name shows, are the scientific study of the behavior of human beings, both in groups and individually. There is no past or present information of human beings who were not in groups. The groups may be small, like the family, or large, like a city or nation. But in order to reach complete development, man must be a member of a society. It is true that some individuals are more solitary than others. Some like monks or hermits may decide, for religious or other reasons, to leave their society and live alone. But these are unusual individuals, and even they cannot separate themselves completely from the rest of mankind. A society, then, seems to be the natural environment of mankind. Scholars who study mankind in social organizations are called social scientists. The human behavior which social scientists study is learned behavior. The behavior of the human body as a living organism is studied by the biologist, the biochemist, or the physician. This behavior of man's physical body is inherited through the genetic development of his species. For example, all physically normal and healthy humans learn to walk as their bodies grow and develop. Social scientists concern themselves with the behavior that man must learn so that he can take his place in a social group. In order to be a functioning member of that group, each member must learn to behave in a way acceptable according to the differences among societies. The social scientists are newcomers to academic studies. By the end of the 19th century, the natural sciences had developed a method, by which they were able to understand the physical world. By using the scientific method, chemists, physicists, and astronauts, for example, learned a great deal about the universe. It seemed reasonable to apply the same method to the study of man's social life. Through this kind of study man may learn to understand himself much better. The scientific method is a way of collecting facts in order to describe an existing situation as correctly and completely as possible. The description must consist only of what can be perceived , analyzed, measured and recorded. Feelings and personal opinions or ideas have no place in scientific description. The fact must be observed and described in such a way that another scientist could repeat the same study and get the same results. Which of the following is NOT taken into account in the scientific method?
Choices:
A. Careful observations.
B. Accurate measurements.
C. True feelings and personal ideas.
D. A reasonable analysis.

Question:
A scientist who developed a way to calculate how much water is used in the production of anything from a cup of coffee to a hamburger was awarded the 2008 Stockholm Water Prize. Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of "virtual water ", a calculation method that has changed the nature of trade policy and research. Allan has written seven books and published more than 100 papers. The Stockholm International Water Institute said this idea is now embedded in the production of foods and industrial products. The institute said Allan's work had made a big effect on global trade policy and research, especially in water-scarce regions. "The improved understanding of trade and water management issues on local, regional and global scales are of the highest value for the successful and sustainable use of water resources," it said. "People do not only use water when they drink it or take a shower," the institute said. "Behind the morning cup of coffee, there are 140 liters of water that was used to grow, produce, package and ship the beans." That is about as much water as a person in England uses on average for all daily drinking and household needs. "For a single hamburger, about 2,400 liters of water are needed. In the USA, the average person uses nearly 7,000 liters of virtual water every day." It said that was more than three times the average use of a Chinese person. What effect does the idea of virtual water have?
Choices:
A. It helps us realize the importance of trade.
B. It helps people do successful business.
C. It helps us make use of water scientifically.
D. It tells us how much water we use a day.

Question:
When English as a foreign language is taught to children at the primary and early secondary levels of education, it is generally taught with a general education aim in mind--that is, it is regarded as a "good thing" for them to learn a foreign language as a part of a broad education. There is usually, however, no immediate and specific requirement for such children to make use of the language in any communicative situation. The purpose of learning the language is essentially a "deferred" purpose, deferred till the tertiary level of education, normally at university, where, it is agreed, a knowledge of English would be helpful in their academic studies. Immediate aims of learning English are defined by the requirements of examinations. Inevitably what is taught to primary and secondary level children is not a communicative knowledge of English language use, but a knowledge of how the rules of English operate. The language system is taught by means of systematic audio-lingual drill and exercise techniques based on habit formation theory of learning and a structural description of English. This may be an effective manner of teaching English usage, but it is less certain that an understanding of how these rules are related to language in use for communicative purpose is an automatic result of this instruction. What the thousands of children succeed in learning in this way is what is necessary in order to pass examinations. Whether such examinations accurately reflect the uses to which English will be put at the tertiary level is another matter altogether. Adults, on the other hand, unless they are learning a foreign language for "pleasure" at evening institutes, as a "cultural" and social experience, are generally highly conscious of the use to which they intend to put it. That use is frequently associated with an academic or professional requirement; without a knowledge of the foreign language, their development in their chosen sphere of work could be restricted or at least adversely affected. Which of the following statements is TRUE according to the passage?
Choices:
A. English teaching should prepare children for the passing of examination.
B. English should be taught to children at primary and secondary levels.
C. English teaching should help students with their future academic studies.
D. English teaching at primary and secondary levels should focus only on grammar.

Question:
Drinking green tea is known to be good for you. Some people suggest drinking 2-3 cups of it a day, and I would say at least one is highly advisable. As many people have already known, tea is filled with powerful antioxidants that will help stop free radicals . Free radicals are harmful to our systems in that they can lead to cell and DNA change, even cell death, and can lead to cancer. Green tea has been drunk throughout Thailand, China, India and Japan for centuries. It is known in these places that green tea can help improve digestion and mental clearness and lower one's blood sugar. It can also help control bleeding, so that injuries can be cured more quickly. Some studies even suggest that drinking green tea on a regular basis can help a person lose weight. Green tea can help a person feel fuller throughout the day with its pleasant smell and taste, and just taking the time to smell it can help ease one's hunger. In short, both studies of green tea and its history show that it is a great thing to drink for your health. How can drinking green tea help one lose weight?

Question:
A famous study was done in a school by a professor from a university. At the start of the school year, the teachers were given the names of five children. They were told that these five were the most excellent students in the class. But the fact was that these students were only average ,and they were not the best students at all. Well, guess what? At the end of the year, all the five average students scored among the highest in the class. What made these average students change so much to become top students?The only difference was the change in their teachers' attitude . Because the teachers believed that these five kids were the top students,they expected more from them. And so these five average students began to believe and expect more from themselves. So they worked harder to do as well as they could. Do you know why? If you expect the best from people, they'll usually want to give you their best. A great leader said, "Treat a person just how he appears to be on the outside, and you'll make him even worse. But treat a person like he's already a success,and you'll help make him the best he can be." Like the true story of 7-year-old Johnny, his teacher got so angry with him that one day she said,"Johnny,you're the naughtiest boy in this class. I'm sure you'll never change." The next year Johnny had a new teacher. And on the first day of class,she met with Johnny after school and said,"Johnny, I've heard a lot about you! But do you know that I don't believe a word of it." And every day after that, this new teacher treated Johnny as if he was one of the smartest students even when Johnny did naughty things. Later on, Johnny became a school leader. Because that's the power of our belief and attitude toward children. Why did the writer tell us the story of 7-year-old Johnny?
Choices:
A. To let us know how good his new teacher was.
B. To show the importance of encouragement.
C. To show that the boy was clever enough.

Question:
Gaudi Nanda sees a wearable computer as a handbag --- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where the similarities end: this bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you take an umbrella. This purse can even upload your favorite songs onto your scarf. Surely, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. Dupont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $ 150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip onto your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring - and even, increasingly, for consumers at large. _ According to the passage, the new wearable computers _ .

Question:
My favourite quilt is always on my bed. Even in warm weather. It is not a large quilt but very beautiful: made up of many brightly color1ed woolen squares of every imaginable color1--red, yellow, green, blue, purple, brown, cream. From the start, I loved this quilt. Just to look at it is to feel comforted. How many years have passed since my mother gave the quilt to me and my husband Ray Smith? I can only guess: thirty years? thirty-five? The beautiful little quilt in all the color1s of the rainbow has followed me from one house to another. The same bed, in different bedrooms in different houses in different periods of my life. In this most recent period, the quilt is laid on my bed in a house in Princeton, New Jersey, into which I moved in 2009. My mother visited this house. When she'd visited Ray and me in my former home, less than five minutes from this house, Mom had always helped out in the garden; we would garden together, and we would prepare meals together, while my father, a gifted amateur pianist, played my piano in the living room. Whenever my parents came to visit us, my mother would bring gifts for us: mostly items she had knitted, or sewn. For years, I wore dresses and jackets my mother had sewn. There is nothing so comforting as wearing clothes your mother has sewn or knitted for you. In February 2008 when my husband was in hospital, and after he died unexpectedly a week later, often I lay in bed too exhausted to move, beneath the rainbow-color1ed quilt. The bed became my shelter, and my "nest". My mother's quilt made me realize how love lasts in the most comforting way. We desire comfort, but comfort can come to us from only a few sources. I know that I have been very fortunate. I never stop giving thanks to my wonderful parents who gave me their love, for this quilt on my bed, as special and beautiful in 2013 as it was in the late 1970s.

Question:
Last Sunday, Aron Ralston, an experienced hiker and mountaineer, set off to walk alone through the Bluejohn desert canyon in Utah. He was planning an eight-hour, 21-kilometer hike. While he was climbing through a narrow part of the canyon, a big stone weighing about 400 kilos fell and trapped his right arm. When he failed to return to the mountain camp where he was staying that night, people simply thought he had decided to camp out somewhere in the canyon. When he still had not returned by Tuesday, the alarm was raised, A search party set out on Wednesday evening, but there we no sign and his family began to fear the worst. In fact, Ralston, 27, was lying trapped in the canyon. By Tuesday, he had run out of water. By Thursday, he realized that he would not survive unless he took unusual action, so he used his pocket knife to cut his arm below the elbow . He then climbed down to the bottom of the canyon. There he met two other hikers, who helped him back to safety. He received some help at a local hospital before being carried to St. Mary's hospital in Grand Junction, Colorado for surgery. Ralston's astonishing survival brought equal amounts of praise and criticism. While praising the climber for his bravery and calm, experts also pointed out he had broken the first rule of outdoor pursuits. He had failed to leave words with anyone of where he was going that day. This was in fact Ralston's second near-death experience. In February, he was buried up to the neck in snow by an avalanche while skiing in the Colorado Rockies.

Question:
Standing alone at Browns party,Anna Mackintosh thought about her husband Edward,establishing him clearly in her mind's eye. He was a thin man,forty-one years of age,with fair hair that was often untidy.In the seventeen years they'd been married he had changed very little:he was still nervous with other people,and smiled in the same shy way,and his face was still almost boyish. She believed she had failed him because he had wished for children and she had not been able to supply any.She had been annoyed for this fact over the years and in the end,quite some time ago now,she had consulted Dr.Abbat at Edward's request. In the Browns'rich living room,its walls and ceilings giving out a bright light with a metallic surface of imitation gold,Anna listened to dance music coming from a tape recorder and continued to think about her husband. In a moment he would be at the party too,since they had agreed to meet there,although by now it was three quarters of an hour later than the time he had planned to come. The Browns were people he knew in a business way,and he had said he thought it wise that he and Anna should attend this gathering of theirs. She had never met them before,which made it more difficult for her,having to wait about,not knowing a soul in the room. When she thought about it she felt herself unfairly treated,for although Edward was kind to her and always had been,it was far from thoughtful to be as late as this. Because of her nervous condition she felt afraid and had developed a sickness in her stomach.She looked at her watch and sighed. Which of the following statements is NOT true?
Choices:
A. Edward had changed very little in character and appearance in the seventeen years after he got married.
B. Anna went to the Btowns' house alone.
C. Anna was very anxious to meet her husband
D. It was exactly half an hour after the party began that Edward arrived at the Browns'party.

Question:
The water level of oceans rises and falls alternately twice a day. This movement of water is called the tide. Tides are causer by the pull of the sun and the moon on the earth' s surface; since the moon is closer, it affects the tides more than the sun. When the moon is directly overhead, it actually pulls on the water that is below it. This causes the water level to rise because the water is pulled away from the earth. As the moon disappears over the horizon, the pull lessens and the water level settles back towards the ocean bottom. When the water reaches its highest level, we have high tide. And when the water comes to its lowest level, we have low tide from its lowest point, the water rises gradually for about six hours until it reaches high tide. Then it begins to fall continuously for about six hours until it reaches low tide. Then the cycle begins again. High tide occurs _ .
Choices:
A. every 12 hours
B. every 6 hours
C. every 24 hours
D. every 18 hours

Question:
Jaguar was very rare. It was said that there less than 20 jaguars in the world, one of which was living in the national zoo of Peru. In order to help this jaguar, Peruvians set up a zoo for it, where there were sheep and deer for the jaguar to eat. However, strange enough, no one had ever seen the jaguar hunt the deer and sheep. What they could see was its lying in its cave, sleeping and eating the meat provided by the zoo keepers. At first, people thought that the jaguar felt too lonely, so they found a female tiger to accompany it. However, it did not make too much sense. The jaguar just sometimes went out of its cave with its "girlfriend" for a while before it came back to its house again' It is normal for the jaguar to be lazy here. Tiger is the king of forest but you simply put some small animals around him. That is why the jaguar shows no interest in going out' a visitor said. So people put five wolves into the jaguar's zoo. Since then, the jaguar did not go back to its cave any more . It either stands on top of the hill yelling or runs up and down the hill without sleeping all day long . Actually, one creature without any _ is a lifeless creature. If a man lives without rivals, he is likely to be satisfied with the present and will not fight for the better. He will hold back before all difficulties . Hard environment tends to make successful people . Therefore, we need some rivals to push us to go ahead in all difficulties and competitions in our lives. Due to our rivals, we can bring out our potential to the best. Due to our rivals, we will continuously improve our abilities when competing with them! Why did Peruvians set up a zoo for the jaguar?
Choices:
A. To protect this endangered animal.
B. To entertain people.
C. To satisfy people's curiosity.
D. To do some experiments.

Classrooms Students from year 0--8 stay in the same classroom for most subjects and move to other classrooms only for specific subjects. Even when they move from one classroom to another, they mostly stay together as a class. In year 9, students take some courses with their homeroom class and some optional classes with students from different classes. Starting from year 10, students no longer stay in the same classroom most of the time nor do they move around with their classes. They go to different classes based on their own choice and abilities. Term Dates A school year starts in January and ends in December. There are four terms in a year. Each term is about 10 weeks. Class Schedule School starts at around 8:30 and ends at 15:15. There are only five periods a day and a period is about an hour long. In the morning, around 10:30, there will be a 20--30 minute interval when students and staff have morning tea.

Question:
Motorists who used to listen to the radio or their favorite tunes on CDs may have a new way to entertain themselves, after engineers in Japan developed a musical road surface. A team from the Hokkaido Industrial Research Institute has built a number of"melody roads,"which use cars as tuning forks to play music as they travel. The concept works by using grooves .They are cut at very specific intervals in the road surface. The melody road uses the spaces between to create different notes. Depending on how far apart the grooves are, a car moving over them will produce a series of high or low notes, and designers are able to create a distinct tune. Paten documents for the design describe it as notches "formed in a road surface so as to play a melody without producing simple sound or rhythm and reproduce melody-like tones". There are three musical strips in central and northern Japan--one of which plays the tune of a Japanese pop song. Reports say the system was invented by Shizuo Shinoda. He scraped some markings into a road with a bulldozer before driving over them and found that they helped to produce all kinds of tones. The _ speed for melody road is 44kph,but people say it is not always easy to get the intended sound. "You need to keep the car windows closed to hear well,"wrote one Japanese blogger."Driving too fast will sound like playing fast forward, while driving around 12mph[20km/h]has a slow-motion effect, making you almost car-sick." According to the passage, melody roads use _ to create different notes.
Choices:
A. cars
B. grooves
C. spaces between intervals
D. bulldozers
