mmlu | Question:
An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space. What can we learn about suborbital spaceflight?
Choices:
A. A trip will return to Earth before finishing a lap.
B. The whole trip will leave passengers weightless.
C. Each trip can take 500 passengers.
D. The trip will be too expensive even for celebrities. | A |

mmlu | Question:
"To be or not to be".Outside the Bible, these six words are the most famous in all the literature of the world.They were spoken by Hamlet when he was thinking aloud, and they are the most famous words in Shakespeare because Hamlet was speaking not only for himself but for every thinking man and woman.To be or not to be----to live or not to live, to live richly and abundantly and eagerly, or to live dully and meanly and scarcely.A philosopher once wanted to know whether he was alive or not, which is a good question for everyone to put to himself occasionally.He answered it by saying, "I think, therefore I am." But the best definition of existence I ever saw was one written by another philosopher who said, "To be is to be in relations." If this is true, then the more relations a living thing has, the more it is alive.To live abundantly means simply to increase the range and intensity of our relations.Unfortunately, we are so constituted that we get to love our routine.But other than our regular occupation, how much are we alive? If you are interested only in your regular occupation, you are alive only to that extent.So far as other things are concerned----poetry and prose, music, pictures, sports unselfish friendships, politics, international affairs----you are dead. On the contrary, it is true that every time you acquire a new interest----even more, a new accomplishment----you increase your power of life.No one who is deeply interested in different kinds of subjects can remain unhappy.The real is the person who has lost interest. Bacon said that a man dies as often as he loses a friend.But we gain new life by contacts with new friends, and new ideas and thoughts, too.Where your thoughts are, there will be your life also.If your thoughts are limited only to your business, only to your physical welfare, only to your narrow circle of the town in which you live, then you live in a narrow restricted life.But if you are interested in the characters of a good novel, then you are living with those highly interested people; if you listen intently to fine music, you are always away from immediate surroundings and living in a world of passion and imagination. To be or not to be ---- to live intensely and richly, or merely to exist, that depends on ourselves.Let us widen and intensify our relations.While we live, let us live. Which of the following behaviors is most probably NOT encouraged by the author?
Choices:
A. Thinking more than your own business.
B. Caring only about your physical welfare.
C. Reading good novels.
D. Listening to fine music. | B |

mmlu | Question:
Have you ever thought about what determines the way we are when we grow up? Remember the TV programSeven Up? It started following the lives of a group of children in 1973. We first meet them as wide-eyed seven-year-olds and catch up with them at seven-year intervals: nervous 14-year-olds, serious 21-year-olds and then grown-ups. Some of the stories are inspiring, others sad, but what is interesting in almost all the cases is the way in which the children's early hopes and dreams are shown in their future lives. For example, at seven, Tony is a lively child who says he wants to become a sportsman or a taxi driver. When he grows up, he goes on to do both. How about Niki? She says, "I would like to find out about the moon." And she goes on to become a space scientist. As a child, soft-spoken Bruce says he wants to help "poor children" and ends up teaching in India. But if the lives of all the children had followed this pattern, the program would be far less interesting than it actually was. It was the children whose childhood did not prepare them for what was to come that made the program so interesting. Where did their ideas come from about what they wanted to do when they grew up? Are children _ by what their parents do, by what they see on television or by what their teachers say? How great is the effect of a single important event? Many film directors, including Steven Spielberg, say that an early visit to the cinema was the turning point in their lives. Dr. Margaret McAllister, who has done a lot of research in this area, thinks that the major factors are parents, friends and their wider society. What does the text mainly discuss?
Choices:
A. New ways to make a TV program interesting.
B. The importance of TV programs to children.
C. Different ways to make childhood dreams come true.
D. The influence of childhood experience on future lives. | D |

mmlu | Question:
Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world's population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis. But that doesn't have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want. Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs. Governments should also protect this resource by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions and pumping it to nearby cropland. No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy. In order to raise the efficiency of the water supply, measures should be taken to _ .
Choices:
A. guarantee full protection of the environment
B. centralize the management of water resources
C. increase the sense of responsibility of agencies at all levels
D. encourage local and regional water resources | B |

mmlu | Question:
Several years ago, a television reporter was talking to three of the most important people in America. One was a very rich banker, another owned one of the largest companies in the world, and the third owned many buildings in the center of New York. The reporter was talking to them about being important. "How do we know if someone is really important?" the reporter asked the banker. The banker thought for a few moments and then said," I think anybody who is invited to the Whiter House to meet the President of the United States is really important. " The reporter then turned to the owner of the very large company. "Do you agree with that?" she asked. The man shook his head, "No. I think the President invites a lot of people to the White House. You'd only be important if while you were visiting the President, there was a telephone call from the president of another country, and the President of the US said he was too busy to answer it. " The reporter turned to the third man. "Do you think so?" "No, I don't." he said. "I don't think that makes the visitor important. That makes the President important. " "Then what would make the visitor important?" the reporter and the other two men asked. "Oh, I think if the visitor to the White House was talking to the President and the phone rang, and the President picked up the receiver, listened and then said, "It's for you."

mmlu | Question:
None of our early ancestors could digest milk as adults because their bodies never had to -milk drinking simply wasn't an option.As people began to extract milk from animals, though, some people developed the ability to keep drinking it throughout their lives. Scientists mow know of a milk-related mutation in our genes--the chemical instructions for life that we carry in almost every cell in our bodies.People who have a mutated form of one particular gene can drink milk just fine.People without the mutation tend to get sick from milk. To figure out where, and possibly why, milk drinking started, some scientists have been looking at who has the milk-digesting mutation to day Pattems are striking. Most adults in Northern and Central Europe are able to digest milk--and they do.Cheese, butter and other dairy products are popular in countries such as Sweden, Denmark, Germany and England.Because European settlers dominated North America, most people here can handle milk just fine, as well.That may explain why ice cream is such a popular dessert in the United States. In much of Africa, Asia and South America, on the other hand, people tend to avoid dairy products because they lead to diarrhea and other stomach problems.(That's why you won't typically find cheese on the menu at a Chinese, Japanese or Ethiopian restaurant.) Native Americans are also unable to digest milk. Based on these genetic patterns, scientists have long thought that milk drinking started in Northern Europe, where dairy is an institution and the milk-digesting mutation is everywhere. A recent study painted a different picture.With a computer model, Thomas and colleagues looked at the spread of the milk-drinking mutation, farming and other related factors.Working backward, the scientists concluded that the first milk-drinkers lived in Central Europe around what's now Hungary about 7500 years ago.The practice didn't start farther north, as scientists had thought before. The main focus of the scientists' research was _ .
Choices:
A. mutation of human genes
B. development of the human stomach
C. why milk drinking started
D. where milk drinking first started | D |

They say that the real marathon begins at 35 kilometers -- the rest is just a warm up. And sure enough, in 2009, at around the 36 kilometer point of the Beijing Marathon I experienced what runners call "hitting the wall". I had been doing well until that point, but suddenly I felt a sharp pain in my leg. My pace slowed down dramatically and every brain cell in my head seemed to be screaming "stop!!!" The last 5 kilometers were not fun; in fact, they were really hard work. Keeping motivated to run those last few kilometers was one of the hardest things I had ever done. But that is what makes running a marathon such a rewarding experience -- if it were easy everyone would do it. I have to admit it is sometimes not even easy to find the motivation to get out of bed, pull on your running shoes and head out into the morning to go for another run. These last two weeks of training for the Muztagata climb have been a little tough. I have been following my training plan for about three months but now I find that my original enthusiasm has all been used up. Day after day of going to the gym is beginning to wear me down and there still seems so much longer to keep this up. I have begun to doubt that I am actually making any progress or getting any fitter and even thought that I might be going backwards! These are all very common experiences for people who are working towards challenging, longer term goals and I have learned to recognize these "highs" and "lows" in my energy and enthusiasm. Over the years I have learned a number of tricks that help me to deal with the days when my early motivation seems to have abandoned me for good. What is the author going to talk about in the following passage?

A. How to get trained.
B. Tips for becoming a marathon runner.
C. How to meet challenges.
D. Tips for keeping motivation high. | D |

"Everything happens for the best," my mother said whenever I faced disappointment. "If you can carry on, one day something good will happen." After graduating from college in 1932, I decided to try for a job in radio, then work my way up to sports announcer . I took the bus to Chicago and knocked on the door of every station. But I was refused every time. In one studio, a nice lady told me that big stations didn't want to accept inexperienced persons. "Go to the countryside and find a small station that'll give you a chance," she said. I returned home, Dixon in Illinois. While there were no radio-announcing jobs in Dixon, my father said Smith Ward had opened a store and wanted a local sportsman to manage its sports department. Since I had played high school football in Dixon, I applied . The job sounded just right for me. But I still failed in the interview. At that moment, mom's words came to my mind: "Everything happens for the best." Dad offered me a car to look for a job. I tried WOC Radio in Davenport in Iowa. The program director, named Peter MacArthur, told me they had already hired an announcer. As I left his office, I felt sad. I asked aloud, "How can a man become a sports announcer if he can't get a job in a radio station?" I was waiting for the lift when I heard MacArthur calling, "What did you say about sports? Do you know anything about football?" Then he made me stand before a microphone and asked me to broadcast an imaginary game. As a result, I did a wonderful job and was told to broadcast Saturday's game! On my way home, I thought of my mother's words again: "Everything happens for the best if you carry on. One day something good will happen." The writer couldn't find a job in Dixon because _ .

The trip to the United State opened my eyes to the fact that there are a lot of similarities as well as differences between American youth and French youth. The first difference is in appearance. Going around in the U.S., I found that American youth do not really care about their appearance. In the morning, they choose something in their closet and wear it with another thing, often of different colors and styles, without wondering whether their choices make them look strange. The reason behind this is that they don't care what people look like, but are just interested in their ideas. I think it's great, but it also causes problems. Since they don't care about their appearance, they don't really care about their weight. Often they get fat without realizing it. There are differences in relationships too. When the American youth fall in love, they don't really think of the future. Also, there are differences in the rules concerning behavior that is allowed. In some _ , the French are more accepting. For example, in America it is generally unacceptable to make physical display of love. Lovers, actually, can't kiss or hold each other everywhere they want. People think that not showing love in public places is a way to respect others. On the contrary, the French youth can do almost everything they want. As for other types of relationships, there are also big differences. Americans act differently from French people in front of unknown people. When an American girl, for example, arrives in front of people she has never met before, she will talk with them, trying to create a kind of tie between her and this new circle of people. The French girls will just think about rather than really do this kind of thing because they are too shy and lacking in self-confidence. To finish, I noticed that in American classes, when pupils want to say or ask something, they just do it. In general, they don't really care how the others will judge them. In France, it's not the same case. If somebody wants to ask something, he/she will think about it before speaking up. I appreciate the freedom in Americans' behavior, ideas, and ways of expressing themselves. The passage is mainly about the _ between American youth and French youth.
Choices:
A. differences
B. friendship
C. similarities
D. relationships | A |

Many children love to play with snow in winter. But Long Chuan has come to hate it. This year his hometown suffered from snowstorms for nearly a month. The heavy snow stopped cars and trains, broke the electricity tower and turned tap water to ice. Every day Long Chuan had to walk several kilometers to carry drinking water. "I couldn't ride a bike and it took me 3 hours to walk to school. I can't remember how many times I slipped on the hard ice, " said Long Chuan. Long is not alone.

Faced with a tough job market, fresh graduates are dreaming of running their own businesses instead. But a recent survey has showed that such ambitions lack the required support and remain just that -- dreams. The Shanghai Municipal Employment Promotion Center poll of 1,276 graduates in several universities and colleges in the city, released last Friday, showed 59.78 percent of respondents considered the possibility of setting up a company or at least a small store. "But they just stop at the 'thinking' stage," it stated. Respondents put the top reasons for not going it alone down to a shortage of investment and a lack of business opportunity. They also listed lack of business experience and social networks, the need for advanced study and objections from family members as factors that stood in their way. More than 90 percent of the interviewees said they would rather take up a job after graduating and then consider starting their own business two or three years down the road. Guo Bing, a senior student in Shanghai International Studies University majoring in English, decided he wanted to be his own boss last year. But he is looking for a job first. "If I fail to find a satisfying job, I would like to establish a company in exhibition services," Guo said. The Shanghai native has some relatives working in a local printing plant. With their help, Guo hopes to produce exhibition brochures at a relatively low price. He is also confident that his English language skills can help him do well in the industry. "Social networking is an important factor leading to business success," Guo said. Guo said that the shortage of graduate jobs is the main reason driving more university students to set up a business right after their graduation. Jiang said the university sets up a business guide team made of government officials and professionals. They regularly give training courses to students who show an interest in having their own business. The parents of university graduates are more willing to help their children start up alone, the survey showed" Once you win the support of your family, you have won half the battle," Guo added. Which of the following statements is NOT true about Guo Bing?
Choices:
A. He has started his own business with the help of his relatives.
B. English is his major in the university.
C. He is trying to find a job which can satisfies him.

mmlu | Question:
Electricity, like clean water, is a resource that's often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet's power comes from:oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks. Companies are trying to offer an alternative, clean energy from renewable resources that's plentiful and portable. Lifton's Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids . The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030. When hydrogen and oxygen molecules combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps. Which of the following statements is NOT true according to the passage?
Choices:
A. Lifton's Medis Technologies is tapping into fuel cells and solar panels.
B. The fuel cell has been around for about 150 years.
C. The fuel cell's commercial development did not begin until the 1960s.

Father was in the army all through the First World War, so up to the age of five, I never saw much of him, and what I saw did not worry me. Sometimes I woke and there was a big figure looking down at me. Sometimes in the early morning I heard the closing of the front door and the sound of shoes walking down. These were father's entrances and exits. Each time he went away, he left me lots of presents--model tanks, knives and all sorts of military equipment which he put in a long box. When he was not there, mother let me get a chair and search through his treasures. She did not seem to think so highly of them as he did. The war was the most peaceful period of my life. Every morning I awoke as soon as it was light and felt myself to be like the sun. Life never seemed so simple and clear and full of possibilities as then. I got up, went into mother's room and climbed into the big bed. She woke and I began to tell her of my plans. I talked but then fell asleep and woke again only when I heard her below in the kitchen, making the breakfast. I often wondered what mother and I should do all day and what present I would get for Christmas. There was that little problem of the baby, for example. Mother and I could never agree about that. Ours was the only house in the street without a new baby, and mother said we could not buy one until father came back from the war as they were very expensive. That showed how simple she was. The Geneys who lived nearby had a baby, and everybody knew that they had hardly any money at all. Maybe it was a cheap baby, and mother wanted something really good, but I felt this did not really matter. The Geneys' baby would have been fine for us. When father was away, mother asked the writer to _ .

mmlu | Question:
We would probably all be amazed if we watched a videotape of ourselves performing basically unconscious acts as we go about the business of the day. These unconscious acts consist of all the little personal habits that we don't even think about, but definitely should. These are some of the things that present an image of who we are to others, and if we are careless in performing them, this image may well be other than we would like it to be. Parents who insist that their children practice good manners and habits at home are doing them a great service, for these habits then become lifelong and the natural way they do things. It proves true that their unconscious actions will reflect a well-mannered person. People who, for example, eat with both arms on the table at home will likely do so when out. Those who are lazy and slow in private will certainly be so in public. Children who are permitted to be disrespectful to their parents will follow suit with other adults, and will, most likely, become adults who are disrespectful of others. This is an area where the saying "practice makes perfect" may be applied. There is an article about the actress, Audrey Hepburn, known for her beautiful carriage and posture. According to her biographer, her grandmother tied her neck to the back of her chair, at table, so that she would not drop down suddenly over her food, but rather would learn to put only small amounts of food on her spoon or fork and bring them to her mouth. This is a rather extreme "at home" method for the development of erect posture, but it does illustrate the effectiveness of practicing good habits so that, when in public, they are instinctive. Those who eat with both arms on the table at home _ .
Choices:
A. will probably change the habit when eating out with their relatives
B. will probably have the same habit when they have meals in the restaurant
C. will feel embarrassed when having meals with so many strangers in public

A world-famous Canadian author, Margaret Atwood, has created the world's first long-distance signing device , the LongPen. After many tiring book-signing tours from city to city, Atwood thought there must be a better way to do them. She hired some technical experts and started her own company in 2004. Together they designed the LongPen. Here's how it works: The author writes a personal message and signature on a computer tablet using a special pen. On the receiving end, in another city, a robotic arm fitted with a regular pen signs the book. The author and fan can talk with each other via webcams and computer screens. Work on the LongPen began in Atwood's basement . At first, they had no idea it would be as hard as it turned out to be. The device went through several versions, including one that actually had smoke coming out of it. The investing finally completed, test runs were made in Ottawa, and the LongPen was officially launched at the 2006 London Book Fair. From here , Atwood conducted two transatlantic book signings of her latest book for fans in Toronto and New York City. The LongPen produces a unique signature each time because it copies the movement of the author in real time. It has several other potential applications. It could increase credit card security and allow people to sign contracts from another province. The video exchange between signer and receiver can be recorded on DVD for proof when legal documents are used. "It's really fun", said the owner of a bookstore, who was present for one of the test runs. "Obviously you can't shake hands with the author, but there are chances for a connection that you don't get from a regular book signing." The response to the invention has not been all favorable. Atwood has received criticism from authors who think she is trying to end book tours. But she said, "It will be possible to go to places that you never got sent to before because the publishers couldn't afford it." How could the LongPen be used in the future?
Choices:
A. To draft legal documents.
B. To improve credit card security
C. To keep a record of the author's ideas.
D. To allow author and fan to exchange videos | B |

Many thousands of Chinese are studying at schools in the United States. And writer Liel Leibovitz says the students are following an example that began in the eighteen seventies. Mr. Leibovitz and writer Matthew Miller joined forces to tell the story of the students in their book, "Fortunate Sons." The book says China sent one hundred twenty boys from 1872 to 1875 to America to learn about developments that could help modernize their country. Mr. Leibovitz got the idea for the book about the boys a few years ago when he was traveling with his wife in China. Mr. Leibovitz learned that Qing government sent a whole delegation of boys to learn the ways of the West. The goal was for them to return to China and help their country. The book says the boys received their American training in Massachusetts, New York, New Jersey and Connecticut. It must have been a very good education. Mr. Leibovitz says the first prime minister of the Chinese Republic completed this program. And so did the first engineer to build a large-scale railroad without foreign help. The same was true of the fathers of Chinese education, diplomacy and the Navy. The book-writers had only to open some boxes containing the writings of these men to learn about them. Their notebooks, journals, letters and postcards were in English. Mr. Leibovitz said he was lucky to have so much information from events that took place long ago. The students returned to China after about nine years. They no longer spoke Mandarin well enough to answer questions. Police welcomed them home by putting them in jail. The young men were released after about a week. But they were given low-level jobs. Mr Leibovitz says it took about ten years for them to rise to higher positions.

It is a novel that is probably more talked about than read. People think: "It's such a big book! It has such a serious theme!" The feeling that they are going to be taught a long, hard lesson often puts readers off. But really, War and Peace (1869), which tells the stories of five upper-class families in Russia at the time of the 1812 French invasion, is not to be missed. Reading this novel is one of those once-in-a-lifetime experiences, like climbing the Great Wall: You will regret it if you do not try. Earlier this month, USA Today reported that a six-episode War and Peace miniseries produced by the BBC would air next year. With a complex plot and so many characters, readers unfamiliar with the work might be most interested in the characters from the financially-troubled Rostov family of Moscow. Count Rostov has four teenage children. Natasha is in love with Boris Drubetskoy, who is about to become an army officer. Nikolai Ilyich loves the poor Sonya, a ward of the family, but his family is not happy with their relationship. The proud Vera is about to start a happy marriage with a German-Russian officer. The youngest Rostov is the 9-year-old Petya, who, like his brother Nikolai, has his heart set on fighting for his country. The lives of all are about to be changed by the upcoming great war that involves many other major characters of War and Peace, such as Prince Andrei, who goes into a military career partly in order to get away from his unhappy marriage to the socialite Lise. The novel has a great reputation among many kinds of writers and millions of readers. US writer Ernest Hemingway wrote: "I don't know anybody who could write about war better than Tolstoy did." A comment by the great 20th-century Russian short-story writer Isaak Babel shows the rich sense of history that Tolstoy's work conveys. "If the world itself could write, it would write like Tolstoy," Babel commented. What is the author's purpose in writing the passage?

mmlu | Question:
Where on Earth are you? Navigators use lines of latitude and lines of longitude to locate places. Lines of latitude run east and west around Earth. On a map or globe, these lines appear as running sideways or horizontally. Lines of longitude run north and south around Earth. These lines go up and down or vertically on a map or globe. These lines create an imaginary graph paper on the Earth. They make it possible to find an absolute, or exact, location on Earth. They even allow us to give an absolute location to a place out in the middle of the ocean. Lines of latitude tell us how far north or south of the Equator we are. Sailors have used primitive navigation tools, like astrolabes, since ancient times. The astrolabe uses the sun and stars to find an approximate location. Using such tools, they have been able to approximate their distance from the equator. Although their instruments may not have been the high quality we have now, they were incredibly accurate for their time. Lines of longitude tell us how far east or west of the prime meridian we are. Sailors constantly looked for new ways to increase their navigation skills. Still, it wasn't until the 18th century that they were able to measure degrees of longitude. They would have been very envious of the technology available to us today. When we use lines of latitude and longitude together, we can get a very precise location. If we want to identify the absolute location of a point, we look where the latitude and longitude lines cross nearest to that point. We use the coordinates for that point as its address. Many maps today include degrees of latitude and longitude. The best title for this passage is _ .
Choices:
A. The map and the globe
B. Latitude and longitude
C. The equator and the prime meridian
D. Absolute coordinates | B |

Sometimes doing something for yourself - even shopping--can _ . That's the case at charity shops and non-profit stores such as Ten Thousand Villages which helps provide skilled workmen with money in developing countries. Their handicrafts are sold throughout North America in 180 stores, 95 of them operated by Ten Thousand Villages. "People come into the store because we have a lot of interesting things, but then they're drawn to us by the mission ," says organization spokeswoman Juanita Fox. "It just feels good to be making a difference when you're buying something." In the Alexandria, Virginia shop, generals display windows draw you in. They are filled with practical, attractive home furnishings in blue and white, all international in mood. Once inside though, it's clear that this isn't just another import store. On the wall behind the cash register is the following note: "Ten Thousand Villagers provides necessary, fair income to Third World people by marketing their handicrafts and telling their stories in North America. Your Buying Makes a Difference. " The store was opened in 1994 as part of a network of shops across the USA run by the Mennonite Church, which is based in Akron, Pennsylvania. Currently, 60,000 skilled workmen from 32 countries provide goods to the stores, with all proceeds re-invested in the organization. Management of the Alexandria shop is overseen by an all-volunteer board of directors. More than 40 additional volunteers help doing everything from working the register to unpacking stock. Maria Yannopoulos got involved after visiting a store and getting to know another volunteer. "Since we are non-profit, we are really looking for value because the more we sell, the more jobs we can create. Giving someone job rather than charity helps in so many ways. " A large number of people visit Ten Thousand Villagers because _ .

It was getting dark and snow was coming down. Joe was driving home. He'd been unemployed since the factory closed. Most of his friends had left, but he stayed on. After all, he was born here. Suddenly he saw a lady standing on the side of the road and pulled up. She was worried. No one had stopped to help her. Was he going to hurt her? He looked poor and hungry. Joe knew how she felt and said, "My name is Joe and I'm here to help you." All she had was a flat tire, but for an old lady, that was bad enough. Joe changed the tire, but he got dirty and his hands were hurt. _ Joe never thought twice about the money and there were plenty who had given him a hand in the past. He had lived his whole life that way. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she could give that person the assistance that they needed. Later the lady went in a dingy-looking restaurant to grab a bite to eat. The cash register was like the telephone of an out-of-work actor----it didn't ring much. The waitress, who was nearly eight months pregnant, brought a clean towel to her with a sweet smile. The old lady remembered Joe. After the waitress brought the change from a 100-dollar bill, she found the lady gone and something written on a piece of paper, "Someone once helped me out----the way I'm helping you.

Everyone wants to achieve true happiness in life. But the biggest factor holding most of us back is actually our ownselves. The Huffington Post released a list of seven mistakes we need to let go of in order to become happier people. Let's take a look. 1.Placing too much emphasis on fulfillment Those who put a lot of pressure on themselves to be happy feel more lonely on a daily basis than those who do not, according to research conducted at the University of Denver, US. 2. Keeping it all in Keeping it all together during tough times can hurt you. Crying is the body's emotional response to outside triggers .By _ it, you may be damaging your mental and physical health. 3. Looking at your smart phone all the time Connecting with others may be the key to happiness, but a recent University of Michigan study found that the more time participants spent on social networking sites, the less happy they felt. 4. Not moving It's no secret that a healthy lifestyle is a big part of happiness. Something as simple as a walk can help you increase your creativity and expose you to essential vitamins. 5. Not reflecting on the past In a 2013 study on nostalgia and emotion, participants reported a higher sense of physiological comfort when they looked back on the past. Affection for heartwarming memories helps people relate their past experiences to the present in order to create a greater sense of meaning. 6. Resisting change A study on the psychology of choices shows that the human brain naturally tries to avoid loss--but that resistance can cause stress. Whether it's fear of the unknown or fear of losing what you currently have, the pressure to hold on to the present can harm your future life satisfaction. 7.

mmlu | Question:
Just as the English language has changed quickly in the previous century, so has the use of it. After the British Broadcasting Corporation (BBC) was founded in 1927, the particular style of speech of the BBC announcers was recognized as standard English or Received Pronunciation (RP) English. Now, most people still consider that the pronunciation and delivery of BBC announcers is the clearest and most understandable spoken English. English has had a strong relationship with classes and social positions. However, since the Second World War there has been a clear change of attitude towards speech snobbery , and marks of class distinction such as styles of speech have been gradually diminishing, especially in the younger generation. By the end of the 1960s, it had become clear that it was not necessary to speak standard English or even correct grammar to become popular, successful and rich. The fashionable speech of the day was no longer the special right of a special class but rather a defiant expression of classlessness. The greatest single influence of the shaping of the English language in modern times is the American English. Over the last 25 years the English used by many people, particularly by those in the media, advertising and show business, has become more and more mid-Atlantic in style, delivery and accent. In the 1970s, fashion favored careless pronunciation and a language full of jargon, slang and "in" words, a great quantity of which couldn't be understood by the outside world. What is considered modern and fashionable in Britain today is often not the kind of English taught in schools and colleges. Which of the following is NOT true?
Choices:
A. The use of the English language has not changed much in the previous century.
B. BBC announcers speak standard English.
C. English has no relationship with classes and social positions now.
D. Young people don't like class distinction. | A |
mmlu | Question:
Once upon a time, there was a scholar who wanted to gain more knowledge each day even though he had already gained enough knowledge. One day, he came to visit a saint and wanted to be his student. The saint provided some tea. He slowly filled the scholar's cup: the cup was full, yet he kept pouring and pouring. The scholar burst out, "Stop! You can't add anything to something that's already full!" The saint set down the teapot and replied, "Exactly." Whether it's the silence between notes in music, or some open time in your schedule, you need space to act effectively. Yet most of us, myself included, tend to stuff as much as possible into whatever room is available-closets, schedules, budgets, relationships, and even the mind itself. However, some people know how to avoid overstuffing their life. For example, in Australia, it seemed that most people there operated at about 85% of their capacity ,unlike Americans pushing as close to 100% as possible. So when you run into Australians you know in the street, they have time to hang out and talk with you. Remember the cup: its value is in the space, the emptiness it holds. How to empty your "cup"? Be mindful of the element of space, openness , and emptiness in your life. This includes room in a drawer, the volume of air in a kitchen, and open-mindedness in a friend. Sometimes you're just stuck with a big bucket of tasks yet to do. But at least empty the bucket faster than you fill it with new tasks. Put some space between finishing one thing and staring another. For example, after sending one email, take a breath before replying to another one. Drop the stuff you can no longer afford to _ around. At sea level, you can run with a brick in your backpack, but if you're hiking on a mountain, that brick has got to go. We learn that compared to Americans, Australians _ .

One hot night last August, I tried everything I could think of -- toys, songs etc. to make him fall into sleep, but he just couldn't do it. Since I believed that a long night was waiting for me ahead, I had no choice but to bring a TV into his room to kill off the hours until dawn. I was surprised that the moment I turned on the TV the baby became quiet right away and fixed his little eyes brightly on the screen. Not willing to waste an opportunity for sleep, I then tiptoed out of the room, leaving him to watch the boring TV programs. I heard no more of the baby's crying that night and the next morning when I went into his room, I found him still watching TV by himself. I found there was a metaphor in my baby's behavior for the new generation. When I gave my boy some books to go over, he only spit upon them; when I read to him, he did not feel comfortable. And so it is in the schools with my students. I find that our students don't read and they look down upon reading and make light of those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have drawn a conclusion: "Let them watch it!" If television is that much more attractive to children than books, why should we fight against it? Let them watch what they want! Why did the father bring a TV set into his son's room?
Choices:
A. To enjoy some interesting programs together with his son.
B. To help himself pass the long hours ahead of him.
C. To help his son fall asleep sooner.
D. To keep his son from making noises. | B |

In 1837, the historian Carlyle made the first recorded use of the word " queue" .He spoke of the French and their "habit of standing in a queue".Forty years later prefix = st1 /Pariswas the best place to wait in line. However, queuing became popular in Britain too.The Second World War was the golden age of queuing, and people joined any line in the hope that it was a queue for something to buy.This was the source of many Second World War jokes: Shopkeeper to customer: Excuse me, miss, are you pregnant ? Customer: Well, I wasn't when I joined the queue. Today, according to research inAmerica, we (inBritain) can spend up to 5 years of our lives queuing - as compared to twelve months looking for things we have lost.But things may be changing. Many people no longer have the patience to stand in a queue.The law of the jungle has begun to operate at bus stops, with people using their arms to push others out of the way. One way to make life easier is to introduce "queue management".Customers at supermarket cheese counters can now take a ticket with a number which appears on a screen when it is their turn.And while they wait for their number, they can do a bit of shopping. In some booking offices there is also a system telling customers how long they may have to wait before they are served. One of the latest technical progress is the use of an electronic scanner which can read all the contents of your shopping basket or trolley in just a few seconds.If these become popular, queuing in supermarkets may become a thing of the past. But some people just like queuing.One man queued all night for Harrods famous January sale, and then returned home for breakfast at nine o' clock the next morning without going into the shop. The British try to solve the problem of queuing by all the following EXCEPT _ .

A. making a law to prevent queuing
B. telling the customers the waiting time
C. using numbered tickets to put the customers in order
D. checking the price of the goods customers buy with a scanner | A |

Every fall, like clockwork, Linda Krentz of Beaverton, Oregon, felt her brain go on strike. "I just couldn't get going in the morning," she says. "I'd get depressed and gain 10 pounds every winter and lose them again in the spring." Then she read about seasonal affective disorder, a form of depression that occurs in fall and winter, and she saw the light literally. Every morning now she turns on a specially constructed light box for half an hour and sits in front of it to trick her brain into thinking it's still enjoying those long summer days. It seems to work. Krentz is not alone. Scientists estimate that 10 million Americans suffer from seasonal depression and 25 million more develop milder versions. But there's never been definitive proof that treatment with very bright lights makes a difference. After all, it's hard to do a double-blind test when the subjects can see for themselves whether or not the light is on. That's why nobody has ever separated the real effects of light therapy from placebo effects. Until now, in three separate studies published last month, researchers report not only that light therapy works better than a placebo but that treatment is usually more effective in the early morning than in the evening. In two of the groups, the placebo problem was resolved by telling patients they were comparing light boxes to a new anti-depressant device that gives off negatively charged ions . The third used the timing of light therapy as the control. Why does light therapy work? No one really knows. "Our research suggests it has something to do with shifting the body's internal clock," says psychiatrist Dr. Lewey. The body is programmed to start the day with sunrise, he explains, and this gets later as the days get shorter. But why such subtle shifts make some people depressed and not others is a mystery. That hasn't stopped thousands of winter depressives from trying to heal themselves. Light boxes for that purpose are available without a doctor's prescription. That bothers psychologist Michael Terman of Columbia University. He is worried that the boxes may be tried by patients who suffer from mental illness that can't be treated with light. Terman has developed a questionnaire to help determine whether expert care is needed. In any event, you should choose a reputable manufacturer. Whatever product you use should give off only visible light, because ultraviolet light damages the eyes. If you are photosensitive , you may develop a rash. Otherwise, the main drawback is having to sit in front of the light for 30 to 60 minutes in the morning. That's an inconvenience many winter depressives can live with. What is the probable cause of Krentz's problem?
Choices:
A. An unexpected gain in body weight.
B. Unexplained impairment of her nervous system.
C. Weakening of her eyesight with the setting in of winter.
D. Poor adjustment of her body clock to seasonal changes. | D |

Edmund Halley was an English scientist who lived over 200years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Isaac Newton. Who was a brilliant mathematician. Newton thought he had already which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse. Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientist. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again. It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet been called Halley's comet, in his honor. Halley made a surprising but correct prediction in the year _ .

I was in Houston a few weeks ago,and needed to be back home in Austin by midmorning the next day.Though I usually left in the evening,for some reason last time I had to choose to set off after midnight. I was on my way back to Austin when I realized I left an important file,and knew I had to return to get it.I took the first exit I could,but when I rounded the corner,an 18-wheeler was stopped dead in the exit lane.I swerved to avoid it,and then I realized that there was something wrong with my car.So I pulled into a small parking lot and unsurprisingly found the area deserted at 3:15am.I've lived in urban areas most of my life.I'm fairly street-wise and don't become frightened easily,but I knew I was in a pretty tough neighborhood. There was no one in Houston to pick me up.I immediately locked the doors and picked up my phone to call a tow truck.Soon a young man knocked on my driver's side window and asked if he could help me.Judging from his appearance,he was far from a mad man,but I knew he was far more likely to rob than help me.So I lied to him.After a while,he asked again,but this time I politely refused and told him the tow truck was due any minute.He finally said,"Madam,you need help.A tow truck in Houston will arrive anywhere between 45minutes and approximately never (which I knew was true),and you aren't going anywhere until you change your flat tire." After considering thoroughly,I got out.He looked surprised,but got right to work.He changed the tire,returned the seat to its place and said,"Thank you for letting me help you.You gave me a chance when most people would never open the door to someone like me.Would it be okay if I gave you a hug?"When I recovered,I gave him a giant hug.I left with a new tire and a renewed faith in human nature.

If the eyes are the windows of the soul, then the body is the mirror of our feelings. If we are feeling great, we may give our body signals . If we look at someone else's body, we can often tell how they are feeling by their body signals. So reading body language signals is a great tool in daily communication. In case you don't think that learning how to read and use body language is important, here are some numbers for you. 7% of the information we receive is from what people actually say, and 38% of the information we receive is from the tone and the speed of their voice; while 55% of the information we receive is from their body language. These non-verbal signals will help you a lot, but you still need to focus on what people are saying. If you focus too much on their body language signals, you and the person may feel uncomfortable.

In the past two years, his wife, Merlie, and their seven children have said "goodbye" to him four times, most recently last month. Each time it has been unnecessary. Mr. Smart had a hip replacement in February at the Burnie hospital but was rushed back two months later with internal bleeding. "The doctors couldn't stop the bleeding," Mrs. Smart said. Medical staff told Mrs. Smart to contact her family, which includes children in Western Australia. "It took two days for them to get here. We had to hope he _ ." he did. "The doctors were there 24 hours a day and they stopped the bleeding. They brought him back," Mrs. Smart said. "I certainly believe in miracles because I've seen one happen, but it wouldn't have happened if the doctors didn't do what they did." It was the second time Mrs. Smart thought she was losing her husband of 54 years. Two years ago, Mr. Smart was admitted to the Launceston General Hospital after a heart attack and a few days later with intense pain caused by a hemorrhage . Again, the family was called to say goodbye---twice. "I was given a 50-50 chance of coming out of it, " Mr. Smart said. Going through the ordeal (,) then was trying on the family, who had prepared themselves for the worst. But to face the same situation only two years later was hard. The Smarts said the support they received at the Burnie hospital helped them through. And it seems the experience has also left an impression at the hospital. Mrs. Smart said when she rang recently and mentioned her husband's name, the reply was "ah the miracle man". When Mr. Smart was rushed back to the hospital with internal bleeding, _ .

Which is sillier: denying we ever went to the moon or trying to convince the true non-believers? Once upon a time--July 20, 1969, to be specific - two men got out of their little spaceship and wandered around on the moon for a while. Ten more men walked on the moon over the next three and a half years. The end. Unfortunately, not quite. A fair number of Americans think that this whole business of moon landings really is a fairy tale. They believe that the landings were a big hoax staged in the Mojave Desert, to convince everyone that U.S. technology was the "best" in the whole wide world. Which is the harder thing to do: Send men to the moon or make believe we did? The fact is that the physics behind sending people to the moon is simple. You can do it with computers whose entire memory capacities can now fit on chips the size of postage stamps and that cost about as much as, well, a postage stamp. I know you can because we did. However, last fall NASA considered spending $15,000 on a public-relations campaign to convince the unimpressed that Americans had in fact gone to the moon. That idea was mostly a reaction to a Fox television program, first aired in February 2001, that claimed to expose the hoax. The show's creator is a publicity hound who has lived up to the name in more ways than one by hounding Buzz Aldrin, the second man on the moon. Mr. X (as I will call him, thereby denying him the joyous sight of his name in print) recently followed Buzz Aldrin around and called him "a thief, liar and coward" until the 72-year-old astronaut finally lost it and hit the 37-year-old Mr. X in the face. Anyway, NASA's publicity campaign began to slow down. The nonbelievers took the campaign as NASA's effort to hide something while the believers said that $15,000 to convince people that the world was round -- I mean, that we had gone to the moon -- was simply a waste of money. (Actually, the $15,000 was supposed to pay for an article by James E. Oberg, an astronomy writer who, with Aldrin, has contributed to Scientific American.) If NASA's not paying Oberg, perhaps it could put the money to good use by hiring two big guys to drag Neil Armstrong out of the house. Armstrong is an extremely private man, but he is also the first man on the moon, so maybe he has a duty to be a bit more outspoken about the experience. Or NASA could just buy Aldrin a commemorate plaque for his recent touch on the face of Mr. X. According to the writer, which of the following is to blame for the story about the hoax?
Choices:
A. NASA's publicity campaign.
B. The Fox television program.
C. Buzz Aldrin.
D. James E. Oberg. | B |

mmlu | Question:
Zhoukoudian is a small village situated about 50 kilometers to the southwest of Beijing. In the 1920s, archaeologists discovered some prehistoric human bones there which changed people's view of China's history. They came from an unknown species of man and were the first evidence of human life in China thousands of years ago. The remains were three teeth! In 1929, a complete skull was also discovered. Eventually, archaeologists found almost 200 items, including six skulls and more than 150 teeth. These discoveries proved the existence of a human species who lived in the area between 700,000 and 200,000 years ago. Four sites where Beijing Man and his relatives lived were discovered on the northern face of Longgushan. They lived in the caves in the area. However, the life span of Beijing Man was short. About 70% of the people probably died before the age of 14. Fewer than 5% lived to the age of 50. Ashes were found alongside the fossils which showed they had used fire for cooking food and also for light, warmth, and protection against wild animals. This is the earliest evidence of the use of fire anywhere in the world. They also made tools of bones and stones. Unfortunately, when Japan invaded China in 1937, excavations at the Beijing Man Site stopped and most of the fossils disappeared, including a Beijing Man skull. After the People's Republic of China was established in 1949, the work started again. Zhoukoudian was listed as a World Heritage Site in December 1987. It has not only given us important information about prehistoric Asian societies, but also provided amazing evidence about the process of evolution. Today, parts of the caves have been badly affected by rain. Some areas are almost completely covered in weeds, causing serious damage. Pollution from the nearby factories has also led to the problem. This is a very serious matter and the Chinese Academy of Sciences is trying to raise public awareness of protecting it. Beijing Man used fire to do all of the following things EXCEPT _ .

A. light in the dark
B. keep warm
C. scare wild animals away

You know you have to read "between the lines" to get the most out of anything. I want to persuade you to do something equally important in the course of your reading. You have to "mark between the lines". By marking you can make the most efficient kind of reading. There are two ways in which one can own a book. The first is the property right you have by paying for it, just as you pay for clothes and furniture. While full ownership comes only when you have made it a part of yourself and the best way to make yourself a part of it is by writing marks on it. Why is marking up a book _ to reading? First, it keeps you awake. Second, active reading is thinking, and thinking tends to express itself in words. Finally, marking helps you remember the thoughts you had, or the thoughts the author expressed. Reading a book should be like making a conversation, a conversation between you and the author. Although he knows more about the subject than you do, don't let anybody tell you that a reader is only on the receiving end. Understanding is a two-way operation. Reading doesn't mean being a passive empty receiver, the reader has to question himself and question the author. And marking a book can show his own judgment on author's opinion: agreement or difference. What can be the best title for the passage?
Choices:
A. How to Own a Book
B. Mark Between the Lines
C. How to Understand Author
D. Read Between the Lines | B |

"Dr.Papaderos, what is the meaning of life?" The usual laughter followed, and people stirred to go.Dr.Papaderos held up his hands and stilled the room and looked at me for a long time, asking with his eyes if I was serious and seeing from my eyes that I was. "I will answer your question." Taking his wallet out of his hip pocket, he fished into a leather wallet and brought out a very small round mirror, about the size of a quarter.And what he said went like this: "When I was a small child during the war, we were very poor and we lived in a remote village.One day, on the road, I found the broken pieces of a mirror.A German motorcycle had been broken in that place. I tried to find all the pieces and put them together, but it was not possible, so I kept only the largest piece.This one.and, by scratching it on a stone, I made it round.I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun would never shine--n deep holes and crevices and dark closets.It became a game for me to get light into the most inaccessible places I could find. I kept the little mirror, and, as I went about my growing up, I would take it out in spare time and continue the challenge of the game.As I became a man, I got to understand that this was not just a child's game but a metaphor for what I might do with my life.I came to understand that I was not the light or the source of light.But light--truth, understanding, knowledge--is there, and it will shine in many dark places only if I reflect it. I am a fragment of a mirror whose whole design and shape I do not know.Nevertheless, with what I have I can reflect light into the dark places of this world--into the black places in the hearts of men--and change some things in some people.Perhaps others may see and do likewise.This is what I am talking about.This is the meaning of my life. How did Dr.Papaderos get the small round mirror when he was a child?

More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can get big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment. It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck. Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met. Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere. What may happen to computer criminals once they are caught?
Choices:
A. With a bad reputation they can hardly find another job.
B. They may walk away and easily find another job.
C. They will be denied access to confidential records

If you have a little child, who hates sitting in a car seat, then the FreedomRide is the answer to your problem. Would you want to be stuck in an unchangeable position every time you're in the car? No. You wouldn't. When an adult sits in a car for any length of time, we stretch, we change the position, we move our legs again and again. We do this without thinking. But kids in a traditional car seat can't do this. They are stuck in one position, and they can't move. We move because the circulation of blood needs to be recovered in our legs as we sit in the same position for any longer. In a traditional car seat, the child can't move to reduce the pain, so it puts them in anger. The FreedomRide lets them have a little freedom, and still be safe. The 5-Point Harness gives them additional safety over a traditional child car seat. I am the Webmaster for islandbreeze.com, and when JoeySafe asked us to redo their website, I was attracted by this system. That is because I have two small children, both girls, aged 3 and 4 and we obviously use car seats. I lived in Southern California, and every couple of months, my wife, the girls and I, go to see grandma who lives in Nevada. It's a 5-hour drive, so the FreedomRide works well. Our trips are so much better now, especially since there is more room in the car without the car seats. The FreedomRide really did make it easier to go on trips. The only thing you need when you use the JoeySafe instead of your old child car seat is a pillow. Besides, my kids want to take a pillow anyway! As a dad, I feel safe driving with the kids in the FreedomRide. I am a very safety-oriented person. From the text we can infer the FreedomRide is a _ .

"Tiger Mother" parenting raises media storm. A new book written by a self-described Chinese descent on her super-strict parenting--Battle Hymn of the Tiger Motherhas raised media storm and fierce debates in the U.S. Amy Chua is a Yale Law School professor and the mother of two teenage girls. She is the daughter of immigrants of Chinese descent. In the Chinese culture,the tiger symbolizes strength and power. In her book Ms.Chua writes about how she demanded excellence from her daughters. For example,her daughters,Sophia and Louisa,were never allowed to attend a sleep-over,be in a school play,watch TV or play computer games. They couldn't choose their own after-class activities or get any grade less than an A.They had to play piano or violin--and no other musical instruments. She writes that if a Chinese child gets a B--which she says "would never happen"--there would be a screaming,hairtearing explosion".She describes making her 7-year-old daughter play a piano piece perfectly--yelling and not letting her leave the bench even to use the bathroom--until it was. Many people have criticized Chua. Some say her parenting methods were abusive. She even admits that her husband,who is not Chinese,objects to her parenting style. But she says that was the way her parents raised her and her three sisters. Stacy DeBroff,who has written four books about parenting,says Amy Chua's parenting style is not limited to Chinese families. She says it represents a traditional way of parenting among immigrants seeking a better future for their children. But she also sees a risk. When children have no time to be social or to follow their own interests, they might not develop other skills that they need to succeed in life. Stacy DeBroff advised parents not to just repeat the way they were raised. Alison Lo,an assistant professor of marketing at the University of Washington's Bothell campus said, "I don't think Amy is advocating a best practice of parenting style, or that success and achievements are critical yardsticks of a good life. But I can imagine how strong her daughters' college applications are going to be. For many parents whose dreams are seeing their kids graduating from a competitive university,Amy is sharing with the readers that it is achievable by persistent,dedicated parental guidance,"Lo said in an interview with Julie Muhlstein,a columnist with the US-based Heraldnet.com."In that sense,a young adult's giftedness can be born,or made,"Lo continued.

Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia. "Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.[: _ Z _ X _ X _ K] Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade. Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students' academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school. "At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills," according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters. "Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying." "Dating should not be considered a ceremony of growth in middle school," Orpinas concluded. Orpinas' attitude towards dating in middle school is _

A. supportive
B. positive
C. negative

To make Chinese students healthier and stronger, China's Ministry of Education has started a campaign. The campaign asks students to run every school day. Te campaign has started since October last year and will last until April this year. Kids at primary schools have to run 1km per day. It's 1.5kms for middle school students and 2 kms for high school and university students. And records will be set for every student. By the end of April 2009, a primary school student has to run 120kms in total/ A middle school students have to run 240kms by that time. Since the campaign started, people have had different ideas about it. Some people think it is good for students. They think the campaign can make students healthier. Some students have little exercise and the campaign can make them run. But some people don't think so. They think some schools don't have enough place for students to do running. If students have to run on the road, maybe it is not safe. They also think there are many ways to become healthier; running is not the only way. So they think the campaign is not a right decision.

People have always wanted to speak with animals. There are many books about this, especially children books. Now there are also movies, such as Dr. Doolittle. When you watch animals, it seems clear that they can communicate with each other. Many people wonder why people can't also communicate with them. Scientists know how some animals communicate. Bees, for example, use their bodies. They do a kind of dance to give information about food. Birds, on the other hand, share information with sounds. They use certain sounds to protect their homes and to stay together when they fly. Some male birds use lovely songs to attract a female . Other animals communicate with both body movements and sounds. For example, dogs wag their tails when they are happy, and they bark when they are excited. People used to think it was possible to teach human language to animals. Parrots and other birds, for example, can learn to say words. But the birds just repeat the words. They don't understand them. Some American scientists tried to teach English to chimpanzees , close s of human beings. However, this was impossible. Chimpanzees can't move their mouths the right way. They could never learn to speak like people. Then scientists tried to teach human language to chimpanzees in other ways. Some tried with American Sign Language (ASL). Others tried with a simple computer. But chimpanzees could only learn to use a few words. They could never learn to use grammar. Their brains are very different from the brains of human beings. Now some scientists are studying the same points between human and animal language. In fact, some animals use sounds like people do. Dogs, for example, use an unpleasant, low sound to tell other dogs to stay away. People, too, use that kind of voice to say the same things. A dog's noisy bark communicate that something is happening. People use the same high tone when they shout, "Watch out!" Scientists want to understand the language of other animals, such as whales and bears. To do this, they go out to the animals' natural homes. They watch the animals for days or even years. They take pictures and make tape recordings and share the information with other scientists. In this way, they hope to learn more about the way animals communicate, and maybe someday we'll be able to communicate better with them. This passage is mainly about _ .
Choices:
A. how scientists communicate with each other
B. how scientists are studying animals' communication
C. how people might communicate with animals

The invention of the camera goes far into the past. In the 1500s, men were experimenting with cameras that made images. But it was not until the early 1800s that man found a way to make the pictures permanent. Even then, photography was a new field. Most families had their pictures taken by a photographer. People did not own cameras because taking pictures and developing the film were too difficult. In 1884, George Eastman changed photography by inventing a kind of film that fit into a small camera. Because the new film was easy to use, many people began to buy cameras. When they had used up their film, people returned their cameras to the factory. There, the film was developed, and pictures were printed. Then more film was put into the cameras, which was sent back to the owners, along with their pictures.

mmlu | Question:
We've all heard the story of Three Little Pigs. The third pig foiled the hyperventilating wolf by building his house out of bricks, rather than with straw or sticks as his brothers had done. Less commonly known is that the pig later improved his home's safety profile by installing convex security mirrors at key points along the driveway. Well, why not? In the current issue of Animal Behaviour, researchers present evidence that domestic pigs can quickly learn how mirrors work and will use their understanding of reflected images to scope out their surroundings and find their food. The researchers cannot yet say whether the animals realize that the eyes in the mirror are their own, or whether pigs might rank with apes, dolphins and other species that have passed the famed "mirror self-recognition test" thought to be a marker of self-awareness and advanced intelligence. The finding is just one in a series of recent discoveries from the nascent study of pig cognition . Other researchers have found that pigs are brilliant at remembering where food stores are cached and how big each stash is to the rest. They've shown that Pig A can almost instantly learn to follow Pig B when the second pig shows signs of knowing where good food is stored, and that Pig B will try to deceive the pursuing pig and throw it off the trail so that Pig B can hog its food in peace. They've found that pigs are among the quickest of animals to learn a new routine, and pigs can do circus worth of tricks: jump hoops, bow and stand, spin and make word like sounds on command, roll out rugs, herd sheep, close and open cages, play videogames with joysticks, and more. For better or worse, pigs are also slow to forget. "They can learn something on the first try, but then it's difficult for them to unlearn it," said Suzanne Held of the University of Bristol. "They may get scared once and then have trouble getting over it." Pigs can play all the tricks, except _ .
