Article: Late one morning in 20 1 2,headed for lunch in San Francisco,I drove towards one of the toll booths .I heard loud music.It sounded like a party,or a Michael Jackson concert.I looked around.No other cars with their windows open.I looked at the toll booth.Inside it,a young man was dancing. "What are you doing?"I asked. "I'm having a party,"he said. "What about the rest of the people?"I looked over at other booths:nothing moving there. "They're not invited." I had a dozen other questions for him,but somebody in a big hurry to get somewhere started punching his horn behind me and I drove off.But I made a note to myself'.Find this guy again.There's something in his eyes that says there's magic in his toll booth. Months later I did find him again,still with the loud music,still having a party. Again I asked."What are you doing?" He said."I remember you from the last time.I'm still dancing.I'm having the same party." I said."Look.What about the rest of the people" He said."Stop.Do you see other people there?"He pointed down the row of toll booths."Everyday, they just get in the booths,stay for eight hours,do the same motions.Brain is on hold,dead on the job.But I am enjoying my life and I'm going to be a dancer someday." Sixteen people are dead on the j ob,and the seventeenth,in nearly the same situation,finds out another way to live.He and I did have lunch later, and he said. "I don't understand why anybody would think my job is boring.I have a comer office,glass on all sides.I can see the Golden Gate,San Francisco.the Berkeley hills.Half of the western people have vacations here while I can stay here every day and practise dancing for the future success.''

Read the following article and select the best answer. Article: Singing had always been an important part of Gloria Estefan's life. " Since I was three years old, I sang. I sang everything," Gloria said. "Gubans," she added, "are a musical people." Gloria was born in Cuba in 1957. Her family left the country just before Fidel Castro came to power. In Miami, where the family settled, many people did not accept Cuban immigrants. In first grade, she spoke little English, but she worked hard to learn the language. Six months after she entered school, she won an award for reading in English! When Gloria was ten , her father returned from the Vietnam War. Soon, the family realized he wasn't well. They soon found out that he was badly ill. Her mother went back to teaching at school to support the family. Gloria cared for her father and her younger sister. She still made the honor roll, and she still had her music, but Gloria was lonely. However, when the band leader Emilio Estefan came to speak at her high school, Gloria sang for him. He asked her to join his band. It was the beginning of the Miami Sound Machine. Within a few months, the Miami Sound Machine was the top band in Miami. In 1978, Gloria and Emilio married. At first, the Miami Sound Machine was known only in Miami. Then the band signed with CBS Records. Estefan and his band became stars. Since then, the Miami Sound Machine has sold millions of records. Estefan has done more than just singing when Hurricane Andrew hit central Florida in 1992. She used only two weeks to organize an all-star concert that raised $ 2 million for the people who suffered in the hurricane. "We needed a party after that _ ," she said. Estefan said, "You have to stay true to the music you really love to do. There will always be people who will tell you, 'that won't work.' You've got to be firm in spite of difficulties. Stick to it----that's the main thing." Question: Estefan's father was ill _ . - after he returned from Vietnam War - before they left their home country - when they settled down in Miami - as soon as she finished high school
after he returned from Vietnam War

Q: Read the following article and select the best answer. Article: An absolute description of the threat hanging over the world's mammals, reptiles, amphibians(, , ) and other life forms has been published by the well-known scientific journal, Nature. A special analysis carried out by the journal indicates that an astonishing 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened. Many species are already critically endangered and lose to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing for the wild, it now appears, are animals that are currently rated as merely being endangered. In each case, the finger of blame points directly at human activites The continuing spread of agriculture is destroying million of hectares of wild habitats every year, leaving animals without homes, while the introduction of newly-come species, often helped by humans, is also damaging native populations. At the same time, pollution and overfishing are destroying ocean ecosystems. "Habitat destruction, pollution or overfishing either skill off wild creatures and plants or leaves them badly weakened," said Derek Tittensor, an ocean ecologist at the World Conservation Monitoring Centre in Cambridge. "The trouble is that in coming decades, the additional threat of worsening climate change will become more and more common and could then kill off these survivors." The problem, according to Nature, is worsened because of the huge gaps in scientists knowledge about the planet's biodiversity. Evaluations of the total number of species of animals and plants alive vary from 2 million to 50 million. In addition, evaluations of current rates of species' disappearances vary from 500 to 36, 000 a year. "That is the real problem we face," added Tittensor. "The scale of uncertainty is huge." In the end, however, the data indicate that the world is heading cruelty towards a mass extinction-which is defined as one involving a loss of 75% of species or more. This could arrive in less... Question: The direct reason for the extinction of some species is _ . - continuous appearance of new species - destructive activities of human beings - more and more homeless animals - the great change of ocean ecosystem
A: destructive activities of human beings

(Question)
Read the following article and select the best answer. Article: As skies are filled with millions of migrating birds, European scientists say the seasonal wonder appears to be strange: The fatter the bird, tile better it flies. The results of their study led to a theory opposite to a central one of aerodynamics , which says that the power needed to fly increases with weight. For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic. Distance: 5,000 kilometers. Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird' s air stream. Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought that thinner, stronger birds would have the best chance to survive. The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it takes to carry the additional weight. In the study, researchers said their team studied the birds flown at different body weights during 28 simulated flights. They forced a small amount of special water into the birds' bodies so that they could measure the amount of energy burnt during the flight. Question: A red knot wading bird of 100 grams will probably weigh _ before making its nonstop migrating flight. - 50 grams - 100 grams - 150 grams - 200 grams
(Answer)
200 grams
