One big advantage of speaking is that it gives you a chance to control others’ thoughts and actions. Whatever you goal – to have a boss hire you, to __31__ others to vote for the person of your ___32__, or to describe the ___33___ you want your hair cut – the key to success seems to be the ___34__ to speak well.Another obvious advantage of speaking is the chance it provides to __35__ the admiration, respect, or liking of others. __36__ jokes, and everyone will think you are really a wise man. ___37__ advice, and they will be thankful for your help. Tell them all you know, and they will be __38__ by your wisdom. But keep quiet…and it seems as if you will look like a ___39__ nobody.Finally, talking gives you the ___40__ to release energy in a way that listening can’t. When you are ___41__, the chance to talk about your problems can often help you feel better. In the same way, you can often ___42__ your anger by letting it out orally. It is also helpful to __43__ your excitement with others by talking about it, for keeping it inside often ___44___ you feeling as if you might burst.While it is true that talking does have many advantages, it is impossible to __45__ that listening can do good to listeners, too. As you will soon read, being a good listener is one good way to __46__ others with their problems; and what better way is there to have others ___47__ you? As for controlling others, it may be true that it is hard to be persuasive while you are listening, but your ___48___ to hear others out will often leave them ___49__ to think about your ideas in return. Listening is often reciprocal: you get what you ___50___.A B C D31. persist advise persuade suggest32. friend relation choice leader33. method way means plan34. efficiency energy mentality ability35. gain grasp receive seize36.

No living thing can exist by itself: it is part of a system in which all forms of life are joined together. If we change one part of the nature order, this willin its turn almost certainly bring about changes in some other part.The cutting down of forest reduces the supply of oxygen. The killing of weeds and insects by chemicals leads to the widespread poisoning of animals and birds. The throwing of waste products into the ocean hurts life in the sea, while waste gases change the chemical balance of the atmosphere and shut out some of the sun’s necessary life-giving rays.And so we could go on, adding more examples, until in despair we might feel like giving up the struggle to control and keep within limits these harmful human activities. Man is very clever at changing the world around him to satisfy his immediate needs, but he is not so clever at looking far ahead, or at thinking about what the future results of his action might be. Man may well destroy himself in his attempt to be too ambitious.51. The first paragraph tells us that _______.A.everything in nature can’t exist without the help of human beingsB.no living thing can live naturallyC.all living things in nature depend on each otherD.man has known the importance of the balance of nature for a long time52. The examples given in the second paragraph are used as evidence that _______.A.it is only during the last few years that man has generally known the balance of natureB.there are some living things which can exist by themselves without chanceC.all forms of life belong to a system in which all the parts can be changed for one anotherD.we cannot change one form of life without destroying the balance of nature53. The last paragraph suggests that, in his attempt to increase his immediate benefits, ________.A.man often fails to think about their future results of his actionB.man is always too ambitious to plan for distant futureC.man often feels that he will have to give up in despairD.man is always anxious to control and keep his activities within limits54. Which of the following statements is true?A.Cutting down of woods does little harm to human beings.B.Man has to pay much attention to future results of his present action.C.Oxygen comes from forests.D.This passage tells us to try our best to get as much as possible immediately.55. Which of the following is the best title of this passage?A. The Secret of NatureB. The Balance of NatureC. The Order of NatureD. The Chance of Nature(II)The world’s first subway was built in London in 1863. At that time, the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages (the taxis of those days) to get round. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to get to and from work, they would relocate their homes outside of the city. This would help ease the pressure of too many people living in the poor parts of London. From these problems, the idea of the London Underground, the first subway system, was born.The plans for building the Underground met with several problems and delays, but the first track was finally opened in January 1863. A steam train pulled the cars along the first underground which was six kilometres (3.7 miles) long. About 30,000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed) and pleasant decorations inside each of the cars. However, the smoke from the engine soon filled the air in the tunnels with ash and soot, as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems riding the Underground did catch on. It carried nine million riders in its first year.Modern subways have come a long way since the early days of the London Underground. Today there are 94 large underground rapid transit systems round the world. The busiest of these subway systems is the Tokyo Metro which opened in 1927. This efficient subway has two billion riders per year, and “pushers” work on the platforms during busy traffic hours to help push riders onto trains. At times, subway cars have been packed with up to 300 people! Shopping malls built in high traffic stations where riders move from one train to another have also helped the popularity of subways in Tokyo. Stations like the famous Ginza Sugo Eki (Ginza Consolidated Station) include underground department stores, supermarkets, restaurants, and speciality shops. Shoppers never have to go above ground!56. What problems led the British government to build the London Underground?A. overcrowding and traffic jamsB. pollution and overcrowdingC. traffic jams and pollutionD. the subway problems57. What was one major problem with the first subway?A. The subway cars are too small.B. Ticket prices are too expensive.C. The subway was too small.D. Riding the subway was unhealthy.58. How did the London Underground solve this problem?A. It built more tunnelsB. It put fans in the tunnels.C. It made the tunnels larger.59. The last paragraph is mainly about ________.A. the London Underground todayB. subways around the worldC. problems with subwayD. the Tokyo subway60. What is the Ginza Sugo Eki?A. a subway in JapanB. a store in JapanC. a subway station in JapanD. a subway in LondonPaper TwoI.Fill in the blanks with the initials given. 10%The story is a simple one. Chris and Mary are both teachers. They fell in love, got married, and had three children, triplets. Their three children are the focus of their lives. Angel, Joe and William are a 1.w_________ to watch. Unlike other twins or triplets, they are different, not 2.i___________. But they are close friends as well as siblings.

And five years later, she couldn’t 8.e_________ the pain. The family asked her doctor to help her. The doctor told them she needed a healthy kidney. Mary decided to give her one of hers, but she and Linda are not blood relatives. Everyone was doubtful about it. Mary received some tests. To everyone’s 9.s___________, the tests came out positive.After the surgery, Linda has her life back, thanks to her incredibly generous sister-in-law, Mary.

Warm sunshine and gentle rain, along with Ed Rawlings’ expert care, will produce a good crop of oranges this year.But Ed has to fight against Florida’s ______1_____ winter weather. In January and Febr uary, temperatures can destroy Ed’s entire orange crop. Having _____2____ in Florida for the past 35 years, Ed Rawlings is prepared for the frosts. When temperatures drop below _____3_____, Ed tries to save his crop by watering his orange trees. The water freezes and forms a thin layer of ice on the trees.What happens is simple. When the trees are ______4______, the water loses heat and becomes ice. The warmth of the heat it loses is sucked in by the fruit and keeps its temperature at a safe level. Ed Rawlings has _____5_____ used this method to save many orange crops.But Ed still faces some difficulties. The trees should be watered at the _____6____ moment the temperature drops to the freezing point. Also, just the right quantity of water must be used. Too much water can form a thick layer of ice that will break the trees’ branches. Another _____7____ is that wind blows away the heat. So Ed has to worry about not only when but also how often his trees should be watered, and how much water should be used.Computer technology may help Ed with some of these ____8____. With equipment, air and soil ______9_____ and wind speed can be measured. The information is fed into a computer which can tell when temperatures drop to freezing. The computer can correctly _______10_____ thequantity of water to be used and how frequently the trees should be watered. Ed Rawlings will find looking after his orange trees a lot easier with the help of a computer.III.V erb forms. 10%The Atlantic Ocean is one of the oceans that separate the Old World from the New. For centuries it kept the Americas from ________1_______ by the people of Europe.Many wrong ideas about the Atlantic made early sailors unwilling to sail far out into it. One idea was that it _______2______ out to “the edge of the world”. Sailors were afraid that they might sail right off the earth. Another idea was that at the equator the ocean would be boiling hot.The Atlantic Ocean is only half as big as the Pacific, but it is still very large. It is more than 4,000 miles (6,000 km) wide where Columbus _______3_______ it. Even at its narrowest it is about 2,000 miles (3,200 km) wide.Two things make the Atlantic Ocean rather unusual. For so large an ocean it _______4_____ very few islands. Also, it is the world’s saltiest ocean.There is so much water in the Atlantic that it is hard _______5_______ how much there is. But suppose no more rain fell into it and no more water was brought to it by rivers. It _________6_______ about 4,000 years to dry up the ocean. On the average the water is a little more than two miles (3.2 km) deep, but in some places it is much deeper. The deepest spot is near Puerto Rico. This “deep” _____7_____ 30,246 feet – almost six miles (9.6 km).One of the longest mountain ranges of the world ______8_____ from the floor of the Atlantic. This mountain range runs north and south down the middle of the ocean. The tops of a few of the mountains reach up above the sea and make islands.Several hundred miles eastward from Florida there is a part of the ocean ______9____ the Sargasso Sea. Here the water is quiet, for there is little wind. In the days of sailing vessels the crew were afraid they would be becalmed here. Sometimes they were.Today the Atlantic is a great highway. It is not, however, always a smooth and safe one. Storms sweep across it and pile up great waves. Icebergs float down from the Far North across the paths of ships.We now have such fast ways of travelling that this big ocean seems ______10_____ smaller. Columbus sailed for more than two months to cross it. A fast modern steamship can make the trip in less than four days. Airplanes fly from New Y ork to London in only eight hours and fromSouth America to Africa in four!IV.Sentence transformation. 5%1.Mother insisted that I go to bed before 9:30.Mother insisted _________ ________ _________ to bed before 9:30.2.Y esterday I talked to a woman.

(用分词改写成简单句)__________________________________________________________________V.Read and answer. 5%We have recently heard a great deal about the effects of computers on our social and economic organizations. In industry, computers mean automation, and automation means unemployment. Computers in the United States have already begun to take the place of workers whose tasks are simple. The variety of jobs, done only by humans in the past, which the machine can perform more rapidly, accurately and economically, increases with each new generation of computers. If we follow this trend, we will be faced with mass unemployment for all but a handful of highly trained professionals who will be more powerful and overworked than are now.What can we do about it? It is foolish to dream of making history backwards. We cannot pass laws forbidding the advancement of science and technology. The computing machines are here, and they will grow because engineers want to build them, and politic ians want their help in the process of government. In short, they will develop and become popular because they enable us to complete tasks that could never have been done before, no matter how many unskilled labourswe might have set to work. Computers will continue to increase our intelligence for just the same reason that engines continue to strengthen our muscles. The question we must ask is not whether we shall have computers or not, but rather, since we are going to have them, how we can make the most humane and intelligent use of them.Answer the questions in COMPLETE sentences.1.What kind of people have computers begun to replace in the United States?___________________________________________________________________________ _________________________________________________________2.What kind of people will be the first to be employed if computers continue to develop?___________________________________________________________________________ _________________________________________________________3.After reading the article, do you believe that the computers will continue to develop or not?___________________________________________________________________________ _________________________________________________________4.Why will the computers continue to grow?___________________________________________________________________________ _________________________________________________________5.What is the main point the writer is trying to make in the last paragraph?___________________________________________________________________________ _________________________________________________________VI.Translation. 10%1.如果我们的篮球队练习多一些的话,他们本来是可以赢得比赛的。
