Question:
Until late in the 20th century, most Americans spent time with people of generations. Now mid-aged Americans may not keep in touch with old people until they are old themselves.That's because we group people by age. We put our three-year-olds together in day-care center, our 13-year-olds in school and sports activities, and our 80-year-olds in senior-citizen homes. Why? We live away from the old for many reasons: young people sometimes avoid the old to get rid of fears for aging and dying. It is much harder to watch .someone we love disappear before our eyes. Sometimes it's so hard that we stay away from the people who need us most. Fortunately, .some of us have found our way to the old. And we have discovered that they often save the young. A reporter moved her family onto a block filled with old people. At first her children were disappointed. But the reporter baked banana bread for the neighbours and had her children deliver it and visit. Soon the children had many new friends, with whom they shared food, stories and projects. "My children have never been less lonely," the reporter said. The young, in turn, save the old. Once I was in a rest home when a visitor showed up with a baby. She was immediately surrounded. People who hadn't gotten out of bed in a week suddenly were ringing for a wheelchair. Even those who had seemed asleep wake up to watch the child. Babies have an astonishing power to comfort and cure. Grandparents are a special case. They give grandchildren a feeling of security and continuity. As my husband put it, "my grandparents gave me a deep sense that things would turn out right in the end." Grandchildren speak of attention they don't get from worried parents. "My parents were always telling me to hurry up, and my grandparents told me to slow down," one friend said. A teacher told me she can tell which pupils have relationships with grandparents: they are quieter, calmer, more trusting. Seeing a baby, the old people get excited because _ .
Choices:
A. they had never seen a baby before
B. the baby was clever and beautiful
C. the baby brought them the image of life
D. the baby's mother would take care of them

You're not alone, with an Australian survey showing that only 3 percent of smokers who made such resolutions stuck with them.

Question:
Instagram is containing so many photos of food--now a pop-up diner in London is taking advantage of this new trend by letting people settle the bill for their meals simply by uploading photos of their dishes to social networks. I always thought people's taking pictures of their food was kind of silly, but at this new pop-up restaurant in the UK, I'd probably do it too. 'The Picture House' is the world's first pay-by-photo restaurant--you order, click a photo of the food, share on Instagram and eat for free! The restaurant belongs to frozen food giant Birds Eye, who came up with the idea to cash in on people's addiction with photographing food and sharing the pictures online. They conducted a survey and found out that more than half of the British population regularly took pictures of their meals. So they realized it was a better way to advertise their new dining range. The pop-up diner was open in Soho, London for three days in May, and is now moving to other major UK cities. They serve two-course meals that customers don't have to pay for, if they photo and Instagram it. The restaurant is a part of Birds Eye's 'Food for Life' campaign, a new marketing project that aims at changing the way people look at frozen food. "Taking photos of food enables people to show off and to share their mealtime moments--from the everyday to the special," said marketing director Margaret Jobling. The reaction to The Picture House has been great so far. And the pay-by-picture concept has proven to be an effective way. Alternative payment methods are actually gaining popularity among a lot of businesses. Last year, in a cafe in Germany customers pay by how much time they spend there, not by what they eat. 'The Picture House' encourages sharing photos of its food to _ .
Choices:
A. attract more customers
B. raise the price of frozen food
C. create a new social media trend
D. reward the regular customers

Question:
Everybody knows that words can carry messages. People communicate with words. Books, magazines, TV,radio and films all help us to know what is going on in the world and what people are thinking about. Do you think you can communicate without words? A smile on your face shows you are happy or friendly. Tears in your eyes tell others that you are sad. When you put up your hand in class, the teacher knows that you want to say something or ask a question. You shake your head, and people know you are saying "No". You nod and people know you are saying "Yes". Other things can also carry messages. For example, a sign at the bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs on doors tell you where to go in or out. Have you ever noticed there are a lot of signs around you and you receive messages from them all the time? People can communicate in many ways without words. For example, an artist can use his drawings to tell about beautiful mountains, seas and many other things. How can people communicate with each other?
Choices:
A. With words only
B. Only without words.
C. Either with words or without words.
D. Just by using different kinds of signs.

Question:
Most teens I meet these days lack basic social courtesy when dealing with people. My own son, who basically grew up with his grandmother, the original manners expert, has perfect table manners. This is partly because he was exposed to manners at a very young age. However, when we eat at home, he would not practice manners. So I asked him why. He said, "I behave the way I am supposed to behave when I'm out, but when I am at home I want to be comfortable." That's when I realized that most parents, myself included, do teach their children the proper way to behave outside the home, but they are also brought up to believe that at home, anything goes. My answer to him was "good behavior has nothing to do with where you are or whom you are with". Then he answered, "But I behave properly when I'm with others so that they think better of me ." And that is when I realized that I was doing things all wrong. I explained to him that it had nothing to do with what people think. This confused him even more. So I went on to explain that behavior, whether in your everyday interaction with people or at the dining table at home, is an expression of who you are. Well, at the age of 13, he got it. So basically, what I am saying is that teaching your children manners comes with the underlying lesson that it is not about what to do or not to do, but rather , who they are. This way it is not mechanical : it comes from within. Teach your teens or children the basic courtesy of greeting their friends' parents and introducing themselves when they go to someone's home. Teach teenage boys to open the door of a car, or any door for that matter, for any girl, whether they are their girlfriends or not. This includes holding elevator doors or letting women step out of the elevator first. Just remember that teenage boys who practice good manners and courtesy grow up to become men who respect people in general. The author has written this passage in order to _ .
Choices:
A. show his/her son and the son's good behavior to teenage boys
B. introduce his/her son's good manners to us
C. tell teenage boys to form good manners and learn to respect people around
D. tell parents good manners is about their children's usual way of behavior and inner quality

Question:
Teenagers with a bedroom television tend to have poorer diet and exercise habits and lower grades in school than those without one, US researchers said on Monday. While many studies have examined TV viewing habits of young people, researchers at the University of Minnesota School of Public Health said little had been known about the effects in particular for older teenagers of having a bedroom TV. They questioned 781 teenagers, aged 15 to 18, in the Minneapolis area in 2003 and 2004. Of them, 62 % reported having a television in their bedroom. Not surprisingly, those with a bedroom TV were more likely to watch it a lot, clocking four to five more hours in front of a television per week, the researchers said. Many more teens with a bedroom TV were classified as heavy TV watchers than those without one. Girls with a bedroom television reported getting less exercise -- 1.8 hours per week compared to 2.5 hours for girls without a TV. They also ate fewer vegetables, drank more sweetened drinks and ate meals with their family less often. Boys with a bedroom TV reported having a lower grade point average than boys without one, as well as eating less fruit and having fewer family meals. "It is clearly important not to allow your child to have a TV in the bedroom," said Daheia Barr-Anderson, one of the researchers. "When you upgrade your TV in the living room and you have this smaller TV that's out of date but still usable, you should really resist putting it in one of your children's bedrooms," she said in a telephone interview. Who do you think would be most interested in reading this passage?

Question:
Linda and David have traveled by air from London to Sydney, Australia. Linda has promised her mother that she will ring her to let her know that they have arrived safely. This is something she had done ever since she was a child. David thinks it is not a good idea to ring so far, to spend too much, and to say so little. "If there were an accident. " He says, 'they'd know soon enough. Bad news travels fast. " But Linda has promised that she would ring. "However," she says, "'it doesn't cost much when you just think that it's the other side of the world. It's only six pence per second .

Question:
It's hard to be the bearer of bad news,but most of IKEA's print and digital fascinating shots of picturesque rooms and products are fake.Those beautiful,"natural-looking" photos of gorgeous rooms and kitchens are mostly the work of computer magic,adjusted and corrected until they're picture-perfect. Martin Enthed,IT manager for IKEA's in-house communications agency,revealed,"In 2012,12 per cent of its product and concept images was CGI-rendered,increasing to 25 per cent in 2013.Since then,that percentage of rendered images appearing in the company's catalogue and online has tripled.75 per cent of the furniture company's product images today are created by computers." It's a move that first caught the attention of photographers and graphic designers a few years back when the furniture giant announced it would cancel photoshoots in favor of computer-generated imagery(CGI). Enthed said IKEA began shifting equipment in 2009 when company officials called in his team and said they weren't pleased with some previous photos and CG images. "So we looked at all the images they said weren't good and the two of three they said were great,and the ones they didn't like were photography and the good ones were all CG,"Enthed said."Now we only talk about a good or bad image - not what technique created it." It's a not-so-secret strategy used by top companies specializing in home and furniture design,though many consumers remain oblivious. The company claims the shift is another way to reduce its environmental footprint,saying constructing digital files produces less waste.It also helps the home furnishing empire's pocketbooks. It can be concluded from the passage that _ .
Choices:
A. IKEA should be punished because of fake photos
B. IKEA set a good example as the furniture giant
C. IKEA adjusted strategies to answer its need

Question:
The latest Chinese "god song"(an Internet term to describe pop songs that spread virally through the Internet is still making debates between those who view it as a milestone for Chinese pop music going global and those who regard it as a bad image of China. Last week,Little Apple, written and performed by the Chopsticks Brothers, won the AMA International Song Award and _ performed the song at the 2014 American Music Awards in Los Angeles. Another Chinese pop singer, Zhang Jie, won the International Artist Award. But while fans of these singers are thinking highly of the awards and the performance by the Chopsticks Brothers at the AMA celebration, there are others who are less excited. They have questioned the value of the awards and what effect it will have on Chinese culture's "going abroad", saying it may leave foreign audiences with a poor impression of Chinese pop music, and even Chinese culture. The Little Applephenomenon, both home and abroad, can be more easily understood and judged if we look at it from a business view rather than a cultural view. The professional promoters behind the duo have developed a clear strategy to promote the duo and their works, not just this particular song.Little Applewas originally released to promote the duo's filmOld Boys: The Way of the Dragon. From the very beginning a marketing strategy was used to promote the song, which immediately went viral on the Internet due to its repetitive rhythm ,easy-to-remember lyrics , simple and funny dance and, most importantly, grass roots nature. The video accumulated more than 1 billion bits on China's major video websites. Although the song was generally disliked by music professionals who criticized it as "musical junk food",Little Apple's popularity nationally paved the way(...) for promoting the duo internationally. The writer's attitude to the song ofLittle Appleis _ .

Question:
An "apple polisher" is one who gives gifts to win friendship or special treatment. It is not exactly a bribe ,but is close to it. All sorts of people are apple polishers, including politicians and people in high offices -- just about everybody. Oliver Cromwell, the great English leader, offered many gifts to win the support of George Fox and his party, but failed. There are other phrases meaning the same thing as "apple-polishing" -- "soft-soaping" or "butter-up". A gift is just one way to "soft-soap" somebody, or to "butter him up". Another that is just as effective is flattery, giving someone high praise -- telling him how good he looks, or how well he speaks, or how talented and wise he is. Endless are the ways of flattery. Who does not love or hear it ? Only an unusual man can resist the thrill of being told how wonderful he is. In truth, flattery is good medicine for most of us, who gets so little of it. We need it to be more sure of ourselves. It cannot hurt unless we get carried away by it. But we just lap it up for its food value and nourishment, as a cat laps up milk, then we can still remain true to ourselves. Sometimes, however, flattery will get you nothing from one who has had too much of it. A good example is the famous 12th century legend of King Canute of Denmark and England. The king got tired of listening to the endless sickening flattery of his courtiers .They overpraised him to the skies, as a man of limitless power. He decided to teach them a lesson. He took them to the seashore and sat down. Then he ordered the waves to stop coming in. The tide was too busy to listen to him. The king was satisfied. This might show his followers how weak his power was and how empty their flattery. The author thinks that flattery can do good to those who _ .

A. are really excellent
B. lack confidence

Question:
The book, Aliens Ate My Homework, is set in a small town in the United States. By the way the characters talk to each other and the description of items from their daily lives, I think the story takes place within the last 10 years. It is a story about a boy named Rod Allbright who goes to school like any other normal kid. Unfortunately, the class bully always picks on him because he is overweight. While he's working on a school project for the science fair, tiny aliens come, crashing through his bedroom window in a spaceship. They have come to the earth to get another alien, an evil one named BKR. He is known in other galaxies for his cruelties. Rod gets bullied throughout the entire novel. The bully's name is Billy Becker, who is also called BKR! Rod does not discover that Billy is a bad alien until later on. This book has lots of action and the main character is fun to read about. The most exciting part is when the aliens and Rod find out that BKR is Billy Becker and they skip school and go to search his house. They get caught when BKR comes home from school. He traps them in a storing device where he keeps his alien items. They break free of the device and escape from his house with some difficulty. Rod Allbright is fun to read about because he can never tell a lie. This gets him into trouble when the aliens eat his homework and he can't make up an excuse for the teacher. The main idea that the author shares is that there could be other galaxies out in the universe with intelligent life forms who could be almost the same as humans. In this book, the aliens are just like humans in the way they think even though they look different and have a different language. I have learned that if you are nice to people they will be nice in return. This is proven in the book because Rod is nice to the aliens and they return the favor. The tiny aliens come to the earth to _ .

B. do research on the earth

Question:
I have a friend named Monty Roberts who owns a horse ranch in San Isidro. He lets me use his house to hold events to raise money for youth at risk programs. The last time I was there he greeted me by saying, "I want to tell you why I let you use my house. It all goes back to a story about a young man who was the son of a poor horse trainer who would go from stable to stable, farm to farm, training horses. As a result, the boy's high school was continually interrupted . One day in the last year of high school, he was asked to write a paper about what he wanted to do when he grew up. "He wrote a seven-page paper about his goal of owning a horse ranch in great detail. He put a great deal of his heart into the project and even drew a detailed floor plan for the dream ranch. Then the next day he handed it in to his teacher. Two days later he received his paper back. But he got a low mark with a note that read, 'See me after class.' "The boy went to see the teacher after class and asked, 'Why did I receive a low mark?'" "The teacher said, 'This is an unrealistic dream for a young boy like you. You have no money. You come from a poor family. Owning a horse ranch requires a lot of money. There's no way you could ever do it.' Then the teacher added, 'If you will rewrite this paper, I will reconsider your mark.' "The boy went home and thought about it long and hard. He asked his father what he should do. His father said, 'Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.' "Finally, the boy turned in the same paper, making no changes at all. He wrote, 'You can keep the low mark and I'll keep my dream.'"

Question:
When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science. Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material--some of it unearthed by miners in Alaska--to conclude that today's domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man's best friend may have enabled the tough journey from Asia into North America. "Dogs may have been the reason people made it across the land bridge," said Wayne. "They can pull things, carry things, defend you from fierce animals, and they're useful to eat." Researchers have agreed that today's dog is the result of the domestication of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America's domestic dog was that Natives domesticated local wolves, the descendents of which now live with people in Alaska, Canada, and the Lower 48. Dog _ from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of "pure native American dogs," Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America. Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge. Leonard and Wayne's study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. "Dogs must have been useful because they were expensive to keep," Wayne said. "They didn't feed on mice; they fed on meat, which was a very guarded resource." What does the passage mainly talk about _ .

A. the origin of the North American dogs

Question:
Plastics are considered one of the most serious pollutants causing environmental problems. The garbage containing plastics end up in the waterways that eventually flow into the oceans. Accumulation of plastic in the ocean endangers marine life and pollutes the water. Does a plastic continent exist? Yes, a plastic continent does exist and was discovered by Captain Charles Moore a decade ago. The plastic continent is twice the size of Britain and it is the region between the Hawaii Islands and California in the central Pacific Ocean. One of the causes of the lack of marine life in this region is due to pollution and pollutants are none other than plastics. Captain Charles Moore believes plastic waste started accumulating in the 1950s. The plastic continent is the man-made continent of floating plastic waste. The fisher men and the sailors have avoided this region for years. The reasons are: 1. There are no fish here because of the lack of nutrients. 2. The zone also lacks the wind that is essential for sailing. To do research on the ocean pollution, Captain Moore founded Algalita Marine Research Foundation. Other organizations such as Greenpeace supported his cause. The reports of The United Nations Environment Program show that millions of seabirds and marine animals are dying due to the invasion of plastics. The waste plastics can be recycled, but in fact they are being thrown into the oceans. The marine animals mistake these for food and eat them. This leads to their death that affects the marine food chain. To save the oceans from the plastic continent you need to reduce the use of plastics, reuse plastic bags and recycle plastics. What is the direct influence of the plastic continent?
Choices:
A. Local fishermen have to fish in other areas.
B. The water becomes shallow and fish have to move away.
C. The wind is too strong there and it makes sailing more difficult.
D. It makes people realize the importance of protecting the environment.

Once an Englishman named Larry Belmont went to Russia for a holiday. After he got back, some of his friends came. "I had a very dangerous trip while I was in Russia," Larry said. "I went to see a friend in the country when the sun went down, I was still travelling through a forest in a sleigh . It was a long way from my friend's house when about twenty wolves began to follow my sleigh." www.ks5u.com "It was very dark in the forest. There was thick snow on the ground. First I heard the wolves. The noise was terrible! Then I saw long, grey forms among the trees, and soon the wolves were near me. They were running very fast, and they didn't seem to get tired like the horses." "What did you do?" one of Larry's friends asked. "When the wolves got very near," Larry answered, "I put up my gun and shot the first wolf dead. Then all the other wolves stopped and ate it, so my sleigh got away from them for a few minutes. Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes I saw them running among the trees once more. They came nearer again, and then I shot another one of them, and the others stopped once more to eat it. The same thing happened again, and my horses became more and more tired and ran slower and slower until, after two hours, only one wolf was still alive and following me."

Question:
The year was 1932. Amelia Earhart was flying alone from North America to England in a small single--engine airplane. At midnight, several hours after she had left Newfoundland, she ran into bad weather. To make things worse, her altimeter failed.(The altimeter shows the height of the plane above the ground.) At night and in a storm, a pilot is in great difficulty without an altimeter. At times, her plane nearly plunged into the Atlantic Ocean. Just before daylight, there was further trouble. Amelia noticed flames coming from the engine. Would she be able to reach land? There was nothing to do except to keep going and to hope. Amelia Earhart did reach Ireland, and for the courage she had shown, she was warmly welcomed in England and the rest of Europe.

Question:
Joseph Rudyard Kipling, who enjoyed early success with his poems, was born on 30 December 1865 in Bombay, India. Some of Kipling's earliest and fondest memories are of his and sister Alice's trips to the fruit market with their woman servant, or walking with his parents alongside the sea at night. The beautiful days were to end when in 1871 Rudyard and Alice were sent to school in Southsea, England, to live with Captain Holloway and his wife. She ruled the boarding house with punishment and Kipling was often beaten by her and her son. "Then the old Captain died, and I was sorry, for he was the only person in that house as far as I can remember who ever threw me a kind word." So he wrote in his later books. Kipling soon learned to read and found comfort in literature and poetry. Freedom from the Holloway household was gained when he spent one month a year in London with his mother's kind sister Aunt Georgie and her husband, pre-Raphaelite painter Edward Burne Jones and their children. _ In 1877 Kipling's mother returned to England and collected him so that he could attend the United Services College in Devon. Now he was able to settle into the life of a student and in his second year started writing his own Schoolboy Lyric poems printed by his parents. In 1878 his father took him to the Paris Exhibition where he was allowed to wander freely and gained much appreciation for French culture which he wrote about in "Souvenirs of France". Kipling fell in love with literature and poetry _ .

Question:
Just seven years ago, the Jarvik-7 artificial heart was being cheered as the model of human creativeness. The sight of Barney Clark----alive and conscious after trading his diseased heart for a metal-and-plastic pump----convinced the press, the public and many doctors that the future had arrived. It hadn't. After monitoring production of the Jarvik-7, and reviewing its effects on the 150 or so patients (most of whom got the device as a temporary measure) the U.S. Food and Drug Administration concluded that the machine was doing more to endanger lives than to save them. Last week the agency cancelled its earlier approval, effectively banning the device. The recall may hurt Symbion Inc., maker of the Jarvik-7, but it won't end the request for an artificial heart. One problem with the banned mode is that the tubes connecting it to an external power source created a passage for infection. Inventors are now working on new devices that would be fully placed, along with a tiny power pack, in the patient's chest. The first sample products aren't expected for another 10 or 20 years. But some people are already worrying that they'll work---and that America's overextended health-care programs will lose a precious $2.5 billion to $5 billion a year providing _ for a ly few dying patients. If such expenditures cut into funding for more basic care, the net effect could actually be a decline in the nation's health. From the passage we know that Symbion Inc. _ .
Choices:
A. has been banned by the government from producing artificial hearts

Question:
Most magazines, whether online or print, will include book reviews. However, most editors and staff writers are usually too busy to read books and review them themselves. Therefore, writing book reviews can be a great way to get started with a writing career. How do you write a great book review that will be sure to be noticed? Follow these tips to write a really interesting and unique book review. Start with a description of the book. Many people that are reading your review may not know anything about the book you're reviewing. Instead of making readers go find information on their own by searching for the book title, start out with a little description of the book. Make sure you avoid too long of a summary. Start with a short paragraph or so that hits all the major points but doesn't give too much away. You don't want to tell your readers everything about the book, because then they won't have to read it at all. Just give enough information so your readers are interested in reading the book. Be objective. Some magazines like to publish book reviews that are completely impersonal. This means that they want a review of the book that doesn't share your opinion and that in which your opinion isn't obvious from reading what you wrote. If you hated a book, it might not be a great book to review. You probably want to review books that you enjoyed. Avoid talking about how much you liked the book, however. You should not include your personal reaction to the book until the very end, where you include a sentence or two about whether or not you would recommend a book and to whom you would recommend it. Look through a lens . A great way to get your review noticed is to look at a book through a specific lens. Read the book as a feminist would, for example, and talk about what a feminist might say to applaud or criticize the book. You can choose any number of lenses, and feminism is just one choice. An economic lens, a family lens, the lens of a different nationality, or the lens of a child could all be interesting ways to look at a book. If you look at a book in this way, instead of just reading it and forming your own opinion, it will be much more interesting and marketable. This is especially the case if you look at a lens that relates to the subject of the magazine to which you are submitting. Feminist magazines love book reviews about books read through a feminist lens, for example, because it is appropriate to their readership. Talk about the writer's style. Another great way to write a book review is to talk about the writer's style. Anyone can pick up a book and read the story, but it takes an experienced writer to note interesting things about another writer's style and write about them intelligently. Furthermore, most people want to know if a book is easy or fun to read over whether or not the subject matter will interest them. Compared with ordinary readers, a skilled writer does better in _ .
Choices:
A. giving an objective description of a book
B. looking at a book through a specific angle
C. finding a book and understanding its story easily

Question:
When a close friend dies, it often forces you to consider your own death. The more you have in common with the friend, the more his death will make you wonder about your own. Sometimes you will naturally say to yourself, "It could just as easily have been me." Such a death has a way of reminding us how fragile life is, and it may cause you to reassess the direction of your own life. Jack's story is a good example. A successful businessman making a lot of money, Jack didn't spend as much time with his family as he wanted. His job required him to work long hours. But three years ago one of his best friends, a man who worked in the same office, had a heart attack. He died while celebrating his daughter's eighteenth birthday in a restaurant. He was only fifty years old. Not long after his friend's death, Jack started to have a chest pain. Finally he had a good physical check-up. _ . But the chest pain continued. He kept thinking of the death of his friend. Jack thought about how much his friend missed in life and he saw how hard it was for his friend's family to manage after he passed away.

The police Tuesday identified the suspect of the Virginia Tech shooting as Cho Seung-Hui, a native of South Korea,who killed 32 people before taking his own life Monday. "He was a 23-year-old South Korean here in the U.S.as a foreign university student." Flinchum said at a press conference held at Blacksburg, Virginia where the university is located. Cho was an undergraduate student in his senior year majoring in English,Flinchum said.He lived on campus at Harper Hall and his residence was established in Centreville,Virginia outside Washington. Meanwhile,Colonel Steve Flaherty,Superintendent of Virginia State Police, said the same gun was used in the two shootings at the university,suggesting there was only one gunman. Previous reports had said there was a possible second gunman still at large . A total of two attacks took place at Virginia Tech Monday.The first attack happened at a dormitory around 7:15 a.m. and left two people dead, while the second attack took place at the campus two hours later.

Question:
Is it worth it to go to college? This has been questioned a lot recently in America. According to a new survey released by the Pew Research Center, only 40 percent of Americans felt that colleges provided a good value for the cost. At the same time, 86 percent of college graduates still felt it was good for them. There are a number of reasons for such dissatisfaction with college. First, there are plenty of problems with higher education -- poor quality and out-of-control costs are two of the biggest. Second, it is true that college is not for everyone. Plenty of rewarding and important careers do not require college. And due to the slow economy, there may in fact be more graduates than the current job market needs. Besides, anti-college feelings are nothing new. Today, Microsoft's Bill Gates or Apple's Steve Jobs -- both college dropouts -- is often held up as evidence of why all that time sitting in class is better spent elsewhere. However, getting a college education is still a good idea. College graduates earn more, and are more likely to have a job in the first place. According to the statistics last year, the average weekly earnings for someone with some college education but no degrees were $712, compared to $1,038 for a college graduate. That is almost $17,000 over the course of a year and there is an even bigger divide for those with less education. Meanwhile, the unemployment rate was 9.2 percent for those with only some college education and more than 10 percent for those with just a middle school degree, but it was 5.4 percent for college graduates. The economic gaps between college completers and those with less education are getting larger. Although most Americans surveyed by Pew feel doubtful about the value of a college degree, an overwhelming majority of parents Pew surveyed still expect their children to go to college. "It can be inferred that the increased doubt has not significantly influenced decision making." Pew's Taylor says, "Despite the concern about rising costs and other problems, college remains a universal desire in this country." Recently many Americans question _ .

A. the value of receiving college education

Question:
Good manners play an important part in maintaining peace in society. A man with good manners doesn't hurt others' feelings, and therefore he's on good terms with everyone. In this way he helps to keep the peace in society. But a man with bad manners has no respect for others. He uses words carelessly and behaves rudely towards others and causes a lot of unpleasantness. In the end, he himself will suffer the most. Everyone avoids him and he is forced to live alone. To live well in society, money alone is not enough. Even the richest man cannot afford to have bad manners. He may have enough money to buy all things he wants; but if his manners are bad, he will have no friends, and no one can live happily without friends. We should have good manners, for it's human nature to try to get friendship; and friendship has to be earned through our own attitude towards others. If we are kind to others, they will be kind to us, and kindness is the most basic quality of good manners. Bad manners drive away friends as well as our own family members. On the other hand, a man with good manners has many friends. He commands the respect of all those who come into contact with him. He doesn't talk ill about others. Even when he's _ , he tries his best not to upset others. He also feels sorry about the weak and the disabled. There are, however, many people who behave so well outside their homes that they are respected by everyone outside. But in their own homes they are worse than the devil . Such people cannot be said to have good manners. Their behavior will soon be discovered by others. If one's manners are good, one behaves well everywhere, even when one is away from the critical eyes of others. Only such a person can live well in society. People with good manners bring society _ .

Question:
The prefix = st1 /USgovernment has announced plans to list polar bears as a threatened species because of concerns that the ice where they live is melting. But as the BBC's Owen Clegg reports, theUSplans are also important for other reasons. It's estimated that there are no more than twenty-five thousand polar bears living in the wild, and this number could go down by a large amount as the floating ice upon which the bears survive melt away. Now, without admitting the cause of this melt, the US Fish and Wildlife Services are reviewing the bear's living conditions. That action is being taken at all, and marks an important change for the Bush administration; for the first time, it may be forced to acknowledge a link between global warming and its effect on a species. Such a conclusion by an unwilling Bush administration could force far wider changes inWashington's policy towards the environment. This review only came about after a union of environmental groups brought a legal case against the government to take action. Environmentalists, like David Doniger, believe that by calling on the protections of the Endangered Species Act, theUSgovernment may finally be forced to cut back on its sending out greenhouse gases: "It is a very important thing today to have the Bush administration notice that global warming is threatening the existence of the polar bear. Now, it's up to the administration to do something to stop the global warming that's threatening the polar bear." ( David Doniger) The United States is the world's largest emitter of greenhouse gases which are blamed for trapping heat from the sun and changing the earth's climate. Since taking office in 2001, President Bush has refused to make the link with global warming, but the bad, serious situation of the polar bear may force that position to change. What is David Doniger's comment on the review of the bear's living conditions?
Choices:
A. The US government may finally be forced to notice that global warming is totally caused by them.
B. The US government may finally be foced to stop sending out greenhouse gases.

Question:
Many years ago, when I was working as a volunteer at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a blood transfusion from her five-year-old brother. The little boy had the same disease before and had developed the antibodies to fight the illness. The doctor talked to the little boy about what they planned to do, and asked him if he would be willing to give his blood to his sister. I saw him hesitate for a moment. He took a deep breath and said, "Yes, I'll do it if it can save Lisa." As the transfusion was going on, the little boy lay quietly in bed next to his sister. He looked at her and smiled all the time. When everything was done and the colour returned to his sister's face, his smile disappeared and he looked a little afraid. He looked up at the doctor and asked, " Will I start to die now?" He was too young to understand the doctor. He thought he would have to give all his blood to his sister, but he agreed. The doctor waited the little boy to _ .

Question:
Today, most people follow a routine, such that they are caught in a cycle of running around the clock without getting any breathing space to enjoy a satisfying life. If you could only take a pause and inspect your routine with a new outlook, you would find that it is actually easy to make some positive changes in life. Making time for yourself is one such positive change. Waking up early gives you ample time to exercise, have your breakfast peacefully, look after your garden, and then get on with the rest of your day. Morning time can be effectively used for planning the day ahead. As a result, you will get enough time to plan your schedule in a better manner. By maintaining a diary of daily tasks, you offer yourself enough time to prepare your schedule, besides not leaving out the important things that need to be done. By writing down the daily activities at hand, you can make necessary changes to the next day's schedule effectively. You don't have to spend hours in a gym every day to stay fit and healthy. In fact, even if you devote just around 20 to 30 minutes daily to exercises like stretching and walking, it can work wonders. Well, the option of using public transport to save time, at first glance, may not seem to be a good idea. However, by using public transit, you will get the time to read books or make those important calls. You would be amazed to know how reading transforms your thought process and personality as a whole. When you get habitual to watching TV, you waste so much time doing nothing constructive. Many a time, you are not really interested in watching TV. In such cases, you need to break free of this habit and invest your precious time in something worthwhile. Paint something or play a game of chess with your kids. This way, you not only make quality time for yourselves, but also create a positive environment at home. Internet surfing, these days, is one of the top time-wasting activities around. Internet users, over time, get habitual to surfing the Internet purposelessly. In fact, Internet surfing is a kind of addiction which many of us find difficult to get rid of. Thus, reducing the amount of time you are on the Internet is one way to save time for yourself. A fast-paced life should not be an excuse that is used not to look after yourself. In fact, such a lifestyle should be the very reason for you to treat yourself with great care and make more time for yourself. Which of the following does the writer agree with?
Choices:
A. Watching TV daily does no good but harm to you.
B. People should go to a gym to do exercise regularly.
C. Public transport shouldn't be only considered time-wasting.
D. People should slow down and spend more time relaxing.

Question:
Remember those big, colorful books with large pictures of balls or apples when you were a little kid? Those have proven to be helpful, according to a number of studies. Between 1 and 5 years old, introducing books to Children can help greatly because this is usually the age when intellectual capabilities form. At age 1 to 5, a child can decide whether he wants to learn or wants to be a good learner. The road to learning starts here. Their curiosity and imagination are fed with the many pictures, sounds and colors in the books. Children normally began school at 5 years old. But today, they go to school when they are as young as one and a half years old. This is because many parents have recognized that influencing the child's formative years is very important. The fight influence can make the child want to read in the future. Parents should play a part in encouraging children to read. Even just reading them bedtime stories can help children feel the joy and amazement connected to reading. This can help them become better readers and better learners as they grow older. If children are interested in reading books rather than watching television, they can improve many skills besides reading and learning. Books can act as stepping stones to intelligence. However, parents must be very careful not to overpower their children. If they force children to read books that are too hard to understand, they might think reading is boring and lose interest in it. .It is implied in the passage that _ .
Choices:
A. the writer read a lot of books when he was a child
B. parents should never force their children to do anything

Question:
Can software bring dead tongues back to life? Probably yes. A computer algorithm works almost as well as a trained linguist in reconstructing how dead " _ " would have sounded, says a new study. "Our computer system is doing a basic job right now," says Alex Bouchard-Cote, an assistant professor in the department of statistics at the University of British Columbia and lead author of the paper describing the algorithm. But the program does a good enough job that it may be able to give linguists a head start, the statistician added. For centuries, scholars have reconstructed languages by hand: looking at the same word in two or more languages and making educated guesses about what that word's "ancestor" may have sounded like. For example, the Spanish word for man ("hombre") and the French word for man ("homme") developed from the Latin word "homo." The way linguists compare words from descendant languages to reconstruct the parent language is called, appropriately, the comparative method. The early 19th-century linguist Franz Bopp was the first to compare Greek, Latin and Sanskrit using this method. Jacob Grimm, one of the Brothers Grimm of fairy tale fame, used the comparative method to show how Germanic languages developed from a common ancestor. The difference between that and Bouchard-Cote's program, the statistician says, "is we do it on a larger scale." As a proof of concept, Bouchard-Cote fed words from 637 Austronesian languages (spoken in Indonesia, the Philippines, Malaysia and more) into the new algorithm, and the system came up with a list of what the ancestor words of all those languages would have sounded like. In more than 85 percent of cases, the automated reconstruction came within one character of the ancestor word commonly accepted as true by linguists. The algorithm won't replace trained human linguists, but could speed up language analysis. Using a computer to do large-scale reconstruction offers another advantage. Bouchard-Cote says, "With big data sets, you can really start finding regularities ... You might find that certain sounds are more likely to change than others." So Bouchard-Cote's team tested the "functional load hypothesis ," which says that sounds that are more important for two clearly different words are less likely to change over time. A formal test of this hypothesis in 1967 looked at four languages; Bouchard-Cote's algorithm looked at 637. "The revealed pattern would not be obvious if we had not been able to reconstruct large numbers of protolanguages," Bouchard-Cote and his coauthors write in the new study. In addition to simply helping linguists understand how people spoke in the past, studying ancient languages can perhaps answer historical questions. For example, Bouchard-Cote says, "Say people are interested in finding out when Europe was settled. If you can figure out if the language of the settling population had a word for wheel, then you can get some idea of the order in which things occurred, because you would have some records that show you when the wheel was invented." The author probably wants to prove the computer algorithm program led by Bouchard-Cote _ .
Choices:
A. will bring every dead language back to life
B. can take the place of linguists in language analysis
C. is of great help to promote language analysis with big data sets
D. can merely reconstruct Asian-Pacific "protolanguages"

The Oscar winning Russel Crowe has put himself in line for further honors with his acting John Nash, the Nobel Prize-winning mathematician troubled by schizophrenia . A Beautiful Mind pictures Nash as an unusual hero, not just because of his academic achievements, but also because of the courage he displays while battling his illness. In 1947, Nash was one of many great young minds at Princeton. "To find a truly original idea is the only way to distinguish myself." The proud and determined student declared. His exploration of such an idea afforded him little time for the normal socializing. His shyness and straightforward approach brought him few friends. After finally _ a revolutionary new idea, Nash's career took off and his reputation was secured. He balanced research work with teaching, which is where he met the bright and beautiful student Alicia (Jennifer Connelly). Things in his life were going well when his talent for code breaking brought him to the attention of the military who employed him during the early stages of the cold war with Russia. However, the stress of his work made Nash's illness develop. Crowe's performance is perfect. He and Connelly ignite (make something exciting) the film's passionate love story and Connelly's wonderful performance makes the audience moved by Alicia, whose courage, strength and faith in her husband are the primary reasons for his recovery.

Light travels at a speed which is about a million times faster than the speed of sound. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light that you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km. per minute. In some cases, the light from one of tonight's stars had started on its journey to you before you were born. Thus, if we want to be honest, we can't say, "The stars are shining tonight." We have to say instead, "The stars look pretty. They were shining four years ago, but their light has only just reached the earth."

Question:
The Wife-carrying World Championship has been celebrated in a small town in central Finland since 1992. In 1992, the people of the town decided to restart some long-forgotten traditions. Back in the late 1800s, there was a robber called Rosvo-Ronkainen in that area. He was said to only accept men as members of his gang who proved their worth in challenges. At that time, it was also a common practice to steal women from neighboring villages. This event is becoming increasingly popular. A large number of competitors, people, and journalists from Finland to Canada attend the Wife-carrying World Championship every year. The event is famous for its warm and humorous atmosphere. The Wife-carrying World Championship is held on a 253.3 meters long official track. The track has two dry obstacles and a water obstacle, about a meter deep. There are a few basic rules and the winner is the couple who complete the course in the shortest time. The wife to be carried may be your own, or your neighbor's. The minimum weight of the wife to be carried is 49 kg. If she is less than 49kg, the wife will be given a heavy bag to carry. Each time a competitor drops his wife, that couple will be fined 15 seconds. Alongside with the Wife-carrying World Championship, there is also a team competition. The distance is the same but three men in the team carry the wife in turns. At the exchange point the carrier has to drink official "wife-carrying drink". Then he may continue the race.

Sam Philips, who owned the shop where Elvis made the record, liked Presley's songs. He said he would call him some day. About a year later, Philips did call and asked him to cut a record. This first record had "Blue Moon of Kentucky" on one side, and "That's All Right, Mama" on the other. The passage shows that _ .

Question:
I woke up late and had breakfast in a hurry. I had never been late and didn't want my boss to be unsatisfied. However, it seemed that day wasn't a lucky one for me from the very second I left my flat. The moment I wanted to rush downstairs one of my stiletto heels broke. I had to return to change my red shoes. I also had to change my purse and other little things that I had tried to match with the shoes. I was sure I would be late for work. On my way to work I had to wait for over half an hour because of an accident. I had no choice but to wait. I phoned my boss and he told me that it was no problem, but he needed me for the meeting with the Japanese clients that morning. Finally, I arrived at the office one hour later. I had to keep calm and be fresh for the meeting to make the clients sure that our plan was the best for their future commercial project. However, I left the plan I had made the night before at home and was going to present it to the clients. I was about to get angry when I realized that I had a draft of it in my office.

Question:
Dear Editor: While a new school term is about to begin, perhaps we should reconsider the matter of examinations. In July, two writers(letters to the editor) praised the cancellation of exams because they believe "Tests don't tell the whole story". As a teacher who has worked in four countries, I have had the experience that a student who earns good marks is generally a good student, and a student's final mark in a subject is usually a grade average of the year's work. Of course there are expectations, but they do not have the frequency that would give an unfair picture of a student's ability. The simple fact is that proper class work; diligent exam studies and good marks are almost certain indicators of a student's future performance. The opposite is, almost certainly, incompetence. There is no acceptable substitute for competition of quality. How can teachers and future officials determine what a student has learned and remembered? Should we simply take the student's mark for it? Any institution that "liberates" students from fair and formal exams is misguided, if not ignorant and surely the "graduates " of such institutions will lack trustworthiness , not to mention being rejected by foreign universities for graduate or other studies. When all is said and done, I sense that a fear of failure and a fear of unpleasant comparison with others are at the bottom of most ban-exam talks. Excellence and quality fear nothing. On the contrary, they seek competition and desire the satisfaction of being the best. According to the letter, a student's final mark _ .

Question:
Several years ago Robert knew a girl at a party. He loved her at once. But he hadn't enough money to marry her. He went to another village and wanted to borrow five thousand dollars from Peter, one of his classmates. He said he was going to return the money in two years. Peter Black believed him and lent the money to him. And Robert thanked the young man very much. In the past four years Robert married the girl and she had a baby. They lived a happy life, but he didn't give the money back to Peter. One day Peter's mother was ill and needed an operation. He looked for Robert for a few times, but he never met him. One day Peter heard that the young man was in. He hurried there. He knocked at the door for a long time and Robert's wife came out to meet him. "I'm sorry, Mr. Black." said the woman. "My husband has just gone out." Peter thought for a while and said, "Yes, I met him on my way here. He told me that he had left all his money at home and let you return it to me."

Question:
Face masks are commonly used in ceremonies and performances. They not only hide the real face of the mask wearer but they often evoke powerful emotions in the audience--danger, fear, sadness, joy. You might think, because so many things vary cross-culturally, that the ways in which emotions are displayed and recognized in the face vary too. Apparently they do not. Recent research on masks from different cultures supports the conclusion that masks, like faces, tend to represent certain emotions in the same ways. We now have some evidence that the symbolism used in masks is often universal. The research on masks builds on work done by anthropologists, who used photographs of individuals experiencing various emotions. These photographs were shown to members of different cultural groups who were asked to identify the emotions displayed in the photographs. Emotions were identified correctly by most viewers, whatever the viewer's native culture. Coding schemes were developed to enable researchers to compare the detailed facial positions of individual portions of die face (eyebrows, mouth, etc.) for different emotions. What exactly do we do when we scowl? We contract the eyebrows and lower the corners of the mouth; in geometric terms, we make angles and diagonals on our faces. When we smile, we raise the corners of the mouth; we make it curved. Psychologist Joel Arnoff and his colleagues compared two types of wooden face masks from many different societies--masks described as threatening versus masks associated with nonthreatening functions. As suspected, the two sets of masks had significant differences in certain facial elements. The threatening masks had eyebrows and eyes facing inward and downward and a downward-facing mouth. In more abstract or geometrical terms, threatening features generally tend to be angular or diagonal and nonthreatening features tend to be curved or rounded, a face with a pointed beard is threatening; _ is not. The theory is that humans express and recognize basic emotions in uniform ways because all human faces are quite similar, skeletally and muscularly. According to the passage, masks are used in performances to _ .
Choices:
A. disguise the real emotions of the performers
B. cause members of the audience to have strong emotions
C. remind the audience that an illusion is being created
D. identify the cultural background of the performers

Question:
Finally, there is some good news for older dads. A new study shows that their children and even grandchildren may get a health benefit because of their older age. It's based on research into something called telomeres--tips on the ends of chromosomes Some previous studies have connected having longer telomeres with better health and longer lives. Telomeres haven't been proven to cause those benefits in the general population, but a number of researchers think they may hold secrets for things like longevity and cancer. As you age, telomeres shorten. However, previous studies have shown that the older a man is when he becomes a father, the longer the telomeres his children tend to have. The new research confirms that and finds it's extended to the grandchildren. That's a cheerier result for older dads than some other studies in recent years that indicate their kids are at higher risk for things like autism Carol Greider of Johns Hopkins University, who shared a Nobel Prize in 2009 for telomere research but didn't participate in the new study, said it's no surprise that the telomere effect would extend beyond children to grandchildren. She also said that since older fathers also tend to pass more potentially harmful genetic mutations , it's "not at all clear" whether advanced paternal age gives an overall health benefit to children. In a statement, the researchers who conducted the study said their study shouldn't be taken as a recommendation that men reproduce at older ages because there's a risk of genetic mutations. Some previous studies of the impact of older fatherhood have been less encouraging. In 2010, for example, at least two big studies confirmed a link to having children with autism. In 2008, a big Swedish study strengthened evidence linking bipolar disorder to older paternal ages. Which of the following statements about telomeres is NOT true?
Choices:
A. They are the tips on the ends of chromosomes.
B. The older a man gets, the shorter they become.
C. Some researchers have connected them to longevity and cancer.
D. They have been proven to cause better health in the general population.

Question:
"An apple a day keeps the doctor away" is one of the most common sayings in the English languages. This is because apples were one of the first foods that medical professionals recognized as healthy---their benefits became obvious when, quite simply, doctors found that people who ate apples were sick less often than those who did not. Today we have a more specific understanding of why apples are so beneficial to overall health. Apples can help keep your levels of bad cholesterol down. The pectin in apples helps you to maintain cardiovascular health and reduce LDL cholesterol(which is the "bad" kind). Apples themselves do not add cholesterol to your diet and are full of water and fiber to help weaken the cholesterol in other foods you might digest. According to Health Diaries, people who eat two apples per day may lower their cholesterol by as much as 16 percent. Apples are naturally low in calories and high in water content. Eating an apple can satisfy your hunger and keep you from reaching for high-sugar, high-calories snacks. By eating apples, you will be more able to maintain a healthy weight because they fill you up, potentially stopping you from eating food that encourages a waistline increase. Apples contain considerable levels of boron , which helps build healthy bones, and can also prevent diseases like arthritis. Apples are rich in vitamin C, which is known to help build immunity. Studies have shown that apples can decrease the risk of breast cancer and liver cancer. One theory is that the apple skins are responsible for this, so be sure not to take apple skins off before you eat them, as you could remove some of the health benefits. What's the main idea of the passage?
Choices:
A. An explanation of an English saying.
B. How to make full use of apples.
C. Apples are beneficial to our health.
D. How to keep healthy in our daily life.

Question:
Have you ever ''Googled'' yourself? More Americans are Googling themselves-and many are checking out their friends,co-workers and romantic interests,too. In a report Sunday, the Pew Internet and American Life Project said 47 percent of U.S.adult Internet users have looked for information about themselves through Google or another search engine.That is more than twice the 22 percent of users who did in 2002,but Pew senior research specialist Mary Madden was surprised the growth wasn't higher. "Yes,it's doubled,but it's still the case that there's a large number of Internet users who have never done this simple act of plugging their names with search engines,"she said. Americans under 50 and those With more education and income were more likely to self-Google--in some cases because their jobs demand a certain online persona.Meanwhile.Pew found that 53 percent of adult Internet users admit looking up information about someone else. celebrities excluded. Often,it's to find someone they've lost touch with.But looking up information about friends, s,colleagues and neighbors was also common. Although men and women equally searched for online information about themselves.women were slightly more likely to look up information about someone they are dating. In many cases,the search is just done to find someone's contact information.But a third of those who have conducted searches on others have looked for public records,such as bankruptcies and divorce proceedings.A similar number have searched for someone else's photo. Few Internet users say they Google themselves regularly-about three quarters of self searchers say they have done so only once or twice.And most who have done so consider what they find accurate. Pew also found that teens were more likely than adults to restrict who can see their profiles at an online hangout like Facebook or news Corp's MySpace. Which conclusion can we draw from the report?
Choices:
A. Teens would like more people to see them online.
B. Most of the women Internet users tend to make dates online.
C. People are more likely to search for information of others than of themselves.
D. Quite a few Internet users are much concerned about their personal security online.

Question:
I was asked in an email about learning idioms in a foreign language. Maybe I am different from most people,but I do not bother with them. To me they are kind of dessert of language learning. They come at the end of a meal. Once you have filled up with the key words and phrases that are used in a variety of situations,then you can add a few idioms. And by that time, you will be able to pick them up naturally anyway. I find that many learners have trouble with idioms,as if repeating some very colloquial expressions is going to upgrade how they sound in a language. In fact, it is the opposite. Idioms are difficult to use correctly. Yes,occasionally you hear idioms and do not understand. But,in my experience,there are always situations where you do not understand. It is best to focus on the most important words,what they mean and how they are used. Certainly,it is best for a nonnative speaker to stick to standard speech. Some teachers even try to teach the "real language".Then you hear nonnative speakers saying things like "I goanna", "You wane" etc. You will learn all the idioms you need just by exposing yourself to the language. In general,you can save any phrase that you find interesting,and if that includes idioms,go to it. But I would not make any special effort to go after idioms. I,in fact,avoid them. If I come across something in Russian that strikes me as a particularly idiomatic use of words,I just leave it aside; do not even bother trying to learn it. If it keeps on appearing,then I will learn it. How did the writer develop the passage?

Question:
Last year I ruined my summer vacation by bringing along a modern convenience that was too convenient for my own good: the iPad. Instead of looking at nature, I checked my e-mail. Instead of paddling a small boat, I followed my Twitter feed . Instead of reading great novels, I stuck to reading four newspapers each morning. I was behaving as if I were still in the office. My body was on vacation, but my head wasn't. So this year I made up my mind to try something different: withdrawal from the Internet. I knew it wouldn't be easy, since I'm bad at self-control. But I was determined. I started by giving the iPad to my wife. The cellphone signal at our house was worse than in the past, making my attempts at cheating an experience in frustration . I was trapped, forced to go through with my plan. Largely cut off from e-mail, Twitter and my favorite newspaper websites, I had few ways to connect to the world except for the radio--and how much radio can one listen to, really? I had to do what I had planned to do all along: read books. This experience has had a happy ending. With determination and the strong support of my wife, I won in my vacation straggle against the Internet, realizing finally that it was I, not the iPad, that was the problem. I knew I had won when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi. "I don't need it," I said. However, as we return to post-vacation life, a harder test begins: Can I continue when I'm back at work? There are times when the need to know what's being said right now is great. I have no intention of giving up my convenience completely. But I hope to resist the temptation to check my e-mail every five minutes, which leads to checking my Twitter feed and a website ortwo. I think a vacation is supposed to help you reset your brain to become more productive. Here I hope this one worked. What did the author do to keep away from the Internet this year?

Question:
Working hard comes naturally to me. The medical billing company I work for hired me as a claims researcher and in one year promoted me to head of the Northeast Region Follow-Up Team. "When are you going to finish?" My husband Joe said as he climbed into bed. "In a few minutes," I replied. My track record offered Joe little reason to believe me. Finishing was always just a moment or two away. Then after I knew he was sound asleep, I'd gather my paperwork and move to the kitchen table and work for a few more hours. Somewhere along the way , I found my enthusiasm for living was replaced with hard boring work that robbed me of both peace and pleasure. As the company expanded, my responsibility grew heavier every day. Resigning would end the madness and Joe encouraged me to do so daily "Just do it, Annie. Quit . You're heading for a break down." One day an email appeared on my computer screen. When I opened it the words "Administrative assistant for senior vice president" caught my eye .No , I thought . They'd think I was crazy . Who in their right mind would stop back to a secretarial position from a management position? At home that evening my interest in the job persisted. I had ten years of experience as an executive secretary long before I ever arrived at the company. The next morning I told my boss I intended to apply for the job. "You're in for a huge salary cut, and you'll lose your bonus," he said, "You're a leader, Annmarie, not a follower. How is it that you think this makes any kind of sense? You're crazy." "Not yet," I said "But if I stay in this position much longer , I'm pretty sure I'll end up that way." Admittedly the manager of human resources was shocked too, but from a budgetary standpoint it's hard to say no to someone who's asking for a salary cut and a decrease in benefits. That's pretty much a novelty you don't run into every day. I brought to the table a skill set, which included a working knowledge of every department in the operations areas of the company . Though I negotiated to a salary I felt was reasonable for what I was offering , the lost bonus and salary cut brought me to a twenty percent decrease in my income. I closed the door to my office that last day with very few regrets about leaving my management position. By the end of my first day in the new position I knew I had made the right decision. No office, staff, salary , or bonus check can ever replace this new feeling of waking up every morning and actually wanting to go to work. The tasks I perform aid one vice president in particular. When I leave at the end of the day, I take nothing with me but my desire to come back tomorrow knowing that I am respected and appreciated. My husband always tells me I can't put a price on peace of mind, but divorce attorneys are plenty expensive. It looks like my path to peace turned up none too soon! The author decided to change her job , mainly because she _ .

Question:
German academics believe they have solved the centuries-old mystery of the "Mona Lisa" in Leonardo ad Vinci's famous portrait . Lisa Gherardini, the wife of a wealthy Florentine merchant, Francesco del Giocondo, has long been seen as the most likely model for the sixteenth-century painting. Art historians have wondered whether the smiling woman may actually have been da Vinci's lover or mother, or the artist himself. Now experts at the prefix = st1 /HeidelbergUniversitylibrary say old notes made in a book by its owner in October, 1503, confirm that Lisa del Giocondo was indeed the model for the famous portrait in the world. "All doubts about the identity of the Mona Lisa have been removed by a discovery by Dr. Armin Schlechter," the library said in a statement on Monday. "Until then, only 'scant evidence' from sixteenth-century documents had been available. These had left lots of room for doubt, and many different identities were put forward." The comments compare Leonardo to the ancient Greek artist Apelles, and say he was working on three paintings at that time, one of which was a portrait of Lisa del Giocondo. Art experts say the Heidelbergdiscovery is a break-through, and the earliest mention linking the merchant's wife to the portrait. Before this discovery the earliest link dated from around 1550, and was made by Italian official Giorgio Vasari, the library said, adding that there had been doubts about Vasari's reliability. The Heidelbergnotes were actually discovered over two year's ago in the library by Schlechter, a spokeswoman said. Although the findings were published in the library's catalogue, they were not widely publicized, and received little attention until a German broadcaster decided to do some recording there, she said. Who discovered the Heidelbergnotes?
Choices:
A. Francesco del Giocondo.
B. Dr. Armin Schlechter.

Question:
The US company iRobot made a new kind of sub-marine , called the Seaglider, last week. The robotic submarine was developed by researchers at the University of Washington. It is about 1.8 meters long and weighs about 52 kilograms. It moves through water at a speed of up to 20-25 kilometers a day and can stay at sea for up to six months before needing a battery recharged. This special character results from its special propulsion system . Unlike a traditional submarine, the Seaglider does not have a propeller . It has an air tank that is emptied and filled to adjust depth, as well as a pair of wings that help to guide and lead the submarine. A traditional submarine, on the other hand, "puts water inside tanks to make it heavier, or it will expel the water to make it lighter," explained Frederick, a professor at the University of Washington. Each time the Seaglider comes to the surface, it sends the data which it collects to its controllers by satellite. Operators can also send the submarine new information. For example, they can change its course in their office through giving the computer orders. Seagliders are already being used for scientific research, such as environmental studies. iRobot also hopes to sell the submarine to the military . At $100,000 each, the Seaglider is a cheap way to keep an eye on the ocean. "These things can go out there and monitor large areas of ocean because they're very persistent. They can go for thousands of miles on their own. At the same time, you can tell them to stay in one place and they can circle," says Helen Greiner, chairwoman of iRobot. "This is science fiction stuff in many ways, but it's really out there and working." When the Seaglider comes to the surface, it will _ .

Question:
Some people have to use public transport, some dislike it and still some love it. If everyone has a car and drives anywhere they want to go, there will be serious traffic problems on the road. Luckily, trains are a good form of public transport. British people use trains a lot. This is especially so for people who are travelling from London to Paris. Every day about 20 trains leave London. They travel at a very high speed and people feel glad that the trains take only 2 hours and 30 minutes to reach Paris. It's much faster to travel by train than by bus or by car. This is because people have to drive cars or buses very carefully and lowly for many reasons, such as speed limits and traffic jams. However, when you are travelling by train, the speed is almost the same and there is no traffic jam for a train. Besides, Londoners think taking a train is one of the safest ways of travelling on the ground. Trains take quite a number of quality tests while they are made. More importantly, they have to take many safety checks before they are used on the rail track. What's more, trains in Britain are comfortable and provide fine services for their users. When you are on a London train, you will find that the train has comfortable tables and seats where people can sit. They also provide food services and power plugs for personal computers or mobile phone. The main idea of the passage is that _ .
Choices:
A. British people enjoy public transport
B. it's fast to travel from London to Paris

Question:
In times of economic crisis, Americans turn to their families for support. If the Great Depression is any guide, we may see a drop in our sky-high divorce rate. But this won't necessarily represent an increase in happy marriages. In the long run, the Depression weakened American families, and the current crisis will probably do the same. We tend to think of the Depression as a time when families pulled together to survive huge job losses. By 1932, when nearly one-quarter of the work force was unemployed, it had declined by around 25 percent from 1929. But this does not mean that people were suddenly happier with their marriages. Rather, with incomes plummeting and insecure jobs, unhappy couples often couldn't afford to divorce. They feared that neither would be able to manage alone. Today, given the job losses of the past year, fewer unhappy couples will risk starting separate households. Furthermore, the housing market meltdown will make it more difficult for them to finance their separations by selling their homes. After financial disasters family members also tend to do whatever they can to help each other and their communities. A 1940 book, "The Unemployed Man and His Family," described a family in which the husband first reacted to losing his job "with tireless search for work." He was always active, looking for odd jobs to do. The problem is that such an impulse is hard to sustain (continue). For some, the hardships of life without steady work eventually defeated their attempts to keep their families together. The rate rose again during the rest of the decade as the recovery took hold. Millions of American families may now be in the initial (earliest) stage of their responses to the current crisis, working together and supporting one another through the early months of unemployment. Today's economic depression could well generate a similar backlog of couples whose relationships have been irreparably ruined. So it is only when the economy is healthy again that we will begin to see just how many fractured families have been created. In addition to job losses, what stands in the way of unhappy couples getting a divorce?
Choices:
A. Mounting (increasing) family debts.
B. Falling housing prices.
C. Difficulty in getting a loan.
D. A sense of insecurity.

Question:
Why should you learn Sign Language? Do you want to improve your communication with a family member or friend who is deaf? Do you want to be able to communicate with deaf people in general? Would you like to advance in your career by being able to communicate in ASL? Do you want to be a Sign Language interpreter? Sign language is not just a random collection of gestures but a full-blown language in its own right, complete with its own grammatical rules. Each country or region has its own sign language, as different from each other as English is from Spanish. Each version of sign language is somewhat linked to the spoken language in its region. For example, American sign language does share similarities with English, even though it is its own language. The advantages of knowing sign language in addition to a spoken language are many. Communication becomes possible on many levels with the deaf community, with other people either hearing or not in any of the above situations, as well as many more. While other languages take years to learn, American Sign Language can be taught in a much shorter time period. It is one of the easiest languages to learn because most of the signs were developed to mimic the actual word or phrase it is representing. Even the alphabet signs look like the letters of the English alphabet. American Sign Language, or ASL, is the third most used language in the United States. Used by the deaf community, interpreters, and friends and family of the deaf. There are a lot of sites on the internet that not only shows you the sign with video, but will help you practice reading signs as well. Teaching even hearing babies sign language seems to be the fashion in recent years and for good reason. Communicating in sign language is fun and natural as babies naturally use body gestures in early communication. Teaching baby sign language actually appears to enhance the learning of verbal skills and brain development of the children involved. One of the reasons for learning sign language is that it _ .

A. increase self-confidence
