I didn‟t think there would be any difficulty in getting it mended , as there are a whole lot of antique (古董) shops near my home . So I left home one morning carrying the chair with me. I went into the first shop expecting a friendly reception (接待) . I was quite wrong. Then man wouldn‟t even look at my chai r.The second shop, though slightly more polite, was just the same, and the third and, the fourth-so I decided that my approach must be wrong.I went into the fifth shop with a plan in my mind. I placed the chair on the floor and said to the shopkeeper, “Would you like to buy a chair?” He looked it over carefully and said, “Yes, not a bad chai r. How much do you want for it, sir?” “Twenty pounds,” I said. “OK,” he said, “I‟ll give you twenty pounds.” “It‟s got a slightly broken leg,” I said. “Yes I saw that, it‟s nothin g.”Everything was going according to plan and I was getting excited. “What will you do with it?” I asked. “Oh, it will be easy to sell once the repair is done.” “I‟ll buy it,” I said. “What do you mean? You‟ve just sold it to me,” he said. “Yes, I know but I‟ve changed my mind. I‟m sorry. I‟ll give you twenty-seven pounds for it.” “You must be crazy,” he s aid. Then, suddenly the penny dropped. “I know what you want. You want me to repair your chair.” “You‟re right,” I said. “And what would you have done if I had walked in and said, …Would you mend this chair for me‟?” “I wouldn‟t have agreed to do it,” he said. “We don‟t‟ do repairs, not enough money in it and too much trouble. But I‟ll mend this for you, shall we say for a five?” He was a very nice man and was greatly amused (感到有趣) by the whole thing .56. We can learn from the text that in the first shop the writer .A. was rather impoliteB. was warmly receivedC. asked the shopkeeper to buy his chairD. asked the shopkeeper to repair his chair57. The expression “the penny dropped” in the last paragraph means theshopkeeper .A. changed his mindB. accepted the offerC. saw the writer‟s purposeD. decided to help the writer58. How much did the writer pay?A. £5B. £7C. £20D. £2759. From the text, we can learn that the writer was .A. honestB. carefulC. smartD. funnyBA sixth of undergraduates in Beijing this year have registered at driving school. The students, mostly from majors such as business management or international trade, will finish their driving courses within 20 days or so .Training costs have dropped to 2,600 yuan for students, according to the Haidian Driving School in Beijing. The price is not really low , but students will accept it , seeing it as an investment (投资) in their future. Familiarity with the operation of computers and fluent English are the basic skills graduating students need to find a job. But a driver‟s permit has become another factor (因素).“In the job market, owning a driver‟s permit sometimes st rengthens a graduating student‟s competitiveness for a good position,” says Zhou Yang, an undergraduate at the China University of Political Science and Law.Cars will become a necessary part of many people‟s lives in the coming years, and it is difficult to get a permit of campus because of the pressures on working people‟s time. “Having a fulltime job after graduation offers limited time to learn to drive. We senior students have plenty of spare time, plenty of opportunity to learn.” Zhou says.Xu Jian, an official at the driving school, said undergraduates were very able and serious, and could grasp in an hour what ordinary people took four hours to learn. In this driving school, middle –aged people, young women and college students are the main customers.To get a driver‟s permit, a beginner is now required to have at least 86 hours‟ practice before the final road test.60. in Beijing want to learn to drive.A. Most of the undergraduatesB. Many undergraduatesC. Many students in the driving schoolD. Most of the students who learn business or international trade61. The undergraduates are learning to drive because .A. they need this skill to find a good jobB. they like to drive carsC. they will not have any time to learn to drive after they find a full-time jobD. most of them will be able to buy cars in the future62. Which is likely to be Xu Jian‟s opinion of students learning to drive?A. He thought it was better to learn it at college than at work.B. He decided it was a waste of money and time to learn to drive.C. He agreed that they could learn to drive.D. He thought they would spend three times more time to learn to drive63. Which of the following can be the best headline for the passage?A. Students Pay Less to Learn to drive NowB. Students Learn to DriveC. It is Better to Learn to Drive at Colleges.D. Welcome to the Driving School.CIn 1944 a 22-year-old Army medic (卫生兵) was answering a battle-field cry for help when pieces of an exploding German shell tore into him. “Gee doc, I feel like both my arms were blown off,” George Lott told his surgeon as he was rushed into a first-aid station near the front in northeastern France. It was the beginning of a painful 5000-mile journey through three hospitals as doctors tried to save the medic's life.After five operations and two and a half years in Army hospitals, Lott, regained use of his left arm, but his right was painfully paralyzed (使丧失活动能力) , “I begged the doctors to cut off my arm,” he recalls. They did.An orphan since he was two, with a third grade education, Lott has lived on his pension(抚恤金) and Social Security (社会保险金) for the past 40 years. In 1962 he bought a house in Albany, N. Y., not far from the Adirondack Mountains where he hunted and fished. He still has the Purple Heart awarded him after he was wounded, although he has had a difficult time keeping it. His girlfriend, explains the bachelor, has wanted to wear it.“Sometimes I still dream about the guys I held in my arms that were dying,” says Lott, “I'm proud that I fought for my country, but I'm still here, drinking beer. The guys who didn't come back are the real heroes.”64. George Lott got wounded when he was___________.A. fighting shoulder-to-shoulder with other soldiersB. fighting against French soldiersC. in a battlefield crying for helpD. running toward a wounded soldier who was crying for help65. From the passage we can infer that___________.A. Lott has to move about in a wheelchairB. he lost both his armsC. he never got a job after he was woundedD. he has once allowed his girlfriend to wear the medal66. Which of the following is true?A. Lott didn't think much of his wartime service.B. Lott and his girlfriend are proud that he fought for this country.C. Lott feels ashamed that he is still drinking beer.D. Lott lost his Purple Heart.67. Lott thinks that real heroes are ___________.A. those dying people whom he held in his armsB. those who died for their countryC. those who chose not to come back to their countryD. those who fought for their countryDEveryone would like to be a millionaire(百万富翁) , a person with a lot of money, but can you imagine having over $30 million and only being 20 years old? Britney Spears from Kentwood, a small town in Louisiana, is only 20 years old. She is a world famous film star with not only $30 million but also a $2 million house in LA.At her young age, she can look after her family financially (经济上) all her life. This year is a big year for Britney. She is now on a 31-day tour of the US and every concert is a sell-out. That means she plays in front of a crowd of around 18,000 people every time. It‟s a tiring schedule but brings her a lot. When touring, she goes to bed around 1 a.m. and then has a lie-in until 1 p.m. the next day. Her philosophy (人生观) is to take care of the body and relax but always make sure you work hard and have fun.Spears is not pleased with only touring and selling nearly 40 million records so she decided to step into the movie business and try a bit of acting. She made an appearance in “Austin Power 3” this year and she is filming a teenage light play that will come out in March 2003. In this movie, she has a starring role.For Britney, acting is another way to express herself and she is enthusiastic (热心的) about it all. If her movies are successful, her money in the bank is sure to grow by another few million dollars but she does it for the love, not the money, as she herself tells the reporters .68. We can infer (推断) from the text that most millionaires are __________.A. older than 20B. around 20C. in their 30sD. in their 40s69. The underlined word “you” in the first paragraph refers to __________.A. a person in generalB. a special personC. Britney SpearsD. a person interested in money70. Which of the following is not true according to the text?A. Though young, Britney can support her family now.B. While touring, Britney sleeps about 12 hours a day.C. The teenage comedy movie was based on Britney‟s own story.D. Britney will be even richer with her movies successful.第五部分,任务型阅读(10*1)For centuries people dreamed of going into space.This dream began to seem possible when high-flying rockets were built in the early 1900s.In 1903 a Russian teacher named Konstantin Tsiolkovsky figured out how to use rockets for space travel.His plan was the first one in rocket science to use correct scientific calculation. About 30 years later, a U.S. scientist named Robert Goddard built the first rockets that could reach high altitudes. During World War II, German scientists built large rockets that could travel very far and carry dangerous explosives. After the war, scientists from Germany went to the United States and the Soviet Union to help those countries build space rockets.These two countries were soon racing to get to space first. Each of these countries wanted to prove that it was stronger and more advanced than the other one. Both countries also had powerful bombs. People in the United States were worried when the Soviets were first to launch a space satellite, which was called Sputnik. The Soviets were also first to send a person into space. Yury Gagarin orbited the earth in the Vostok I spaceship in 1961.The US government set a goal for its space program to be the first country to put a person on the Moon.The U.S.space program built a series of Apollo spaceship. These vehicles were powered by huge Saturn 5 rockets.In 1969 Apollo II took three班级_______________ 学号_________________ 姓名_________________任务型阅读(10*1)71___________ 72___________ 73_____________ 74____________ 75_____________ 76___________ 77___________ 78_____________ 78____________80_____________单词拼写(10*1)1.Gas is one of the modern _______________ (便利)the new apartment buildingprovides.2.His busy work didn‟t prevent him from going to see his leagues______________(亲自).3.When will the football game be b___________ live on TV?4.He had made _______________(安排) for his trip to Russia before he left.5.Anyone who wants to get the job shall fill in the ________________(申请) formfirst.6.Mr. Smith is a f_____________ visitor to our school library.
