For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark your answer on the Answer Sheet.Passage 1Have you ever noticed advertisements which say, “Learn a foreign language in 6 weeks, or your money back! From the firstday your pronunciation will be e xcellent. Just send …” and so on. Of course it never happens quite like that. The only language that is easy to learn is the mother tongue. And think how much practice that gets. Before the Second World War people usually learnt a foreign language in order to read the literature of the country. Now speaking the foreign language is what most people want. Every year many millions of people start learning one. How do they do it?Some people try at home with books and records or tapes; some use radio or television programs; others go to evening classes. If they use the language only 2 or 3 times a week, learning it will take a long time, like language learning at school.A few people try to learn a language fast by studying for 6 or more hours a day. It is clearly easier to learn the language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary. They need the language in order to do their work better. For example, scientists and doctors need to be able to read books and reports in the foreign language. Whether the language is learnt quickly or slowly, it is hard work. Machines and good books will help but they cannot do the student?s work for him.36.What do the advertisements mean?A. Y ou will learn a lot on the first day.B. Pronunciation is most important in language learning.C. Anyone can learn a foreign language without much money.D. It is possible to learn a language in less than 2 months.37.After the Second World War many people ______.A. found their mother tongue easy to learnB. learn to speak a foreign languageC. don?t learn to read in a foreign la nguageD. only learn to read in a foreign language38.Which, according to the writer, is the best place to learn a foreign language?A. Home.B. Evening classes.C. The country where the language is used.D. Places where people work.39.The writer of the passage thinks that ______.A. it?s difficult to learn a foreign languageB. it?s not necessary for many people to learn a foreign languageC. it?s not important whether a language is learned quickly or slowlyD. it?s much easier to learn a language toda y than in the past40.According to the passage, which statement is true?A. The mother tongue is easy to learn because it is an easy language.B. It is necessary for many of us to go abroad to learn a foreign language.C. Scientists and doctors want to speak an excellent foreign language, so they learn it.D. Though you have good machines and good books to help you learn a foreign language,you must work hard at it.Passage 2During the summer holiday there will be a different schedule for services for the university community. Specific changes for intercampus bus services, cafeteria (自助餐厅) summer hours for the school, hospital and recreational (娱乐的) and athletic (运动的) facilities (设施) will be posted on the bulletin board outside of thecafeteria. Weekly movie and concert schedules which are in the process of being arranged will be posted each Wednesday outside of the cafeteria.Intercampus buses will leave the main hall every hour on the half hour and make all of the regular stops on their route around the campus. The cafeteria will serve breakfast, lunch, and early dinner from 7 a.m. to 7 p.m. during the week and from noon to 7 p.m. on weekends. The library will maintain regular hours during the week, but shorter hours on Saturdays and Sundays. The weekend hours are from noon to 7 p.m..All students who want to use the library borrowing services and the recreational, athletic, and entertainment facilities must have a valid (有效的)summer identification card.

Each type of food contains at least one useful vitamin. For example, fresh fruit contains a lot of vitamin C.Many years ago, people didn?t know about vitamins. When somebody was sick because of lack of vitamins, the doctors didn?t know what to do. For example, they didn?t know a child with rickets (软骨病) needed foods containing vitamin D, e.g. milk, eggs and oily fish.Doctors found out about vitamins by accident. One day a girl aged 4 was ill. The doctors tried to cure her by taking blood from her body but this didn?t succeed. Other doctors put hot c oals on her forehead and used other harmful methods. All these …cures?failed. The girl became worse and worse.One day the girl?s mother was peeling (削皮) apples in the kitchen. The girl came in and ate some of the peel. The next day, her condition was better. The mother thought about the peel and gave her some more. After some days, the girl was much better. The girl?s mother told doctors what had happened. They investigated the chemicals in apple-peel. The results were very interesting, so the doctors started to investigate other food. They discovered the girl had been ill with scurry (坏血病), caused by a lack of vitamin C. In previous centuries, this disease had killed thousands of sailors. When the doctors found out about vitamins, they advised people to eat a variety of different kinds of food.Now, we know this advice is good. Each person needs to eat such things as rice, meat, fish, vegetables and fruit. Milk and butter are good, too.46.which of the following statements is right?A. None of food contains one useful vitamin.B. All of food doesn?t contain one useful vitamin.C. There is n o food which doesn?t contain any useful vitamin.D. All food contains many useful vitamins.47.Before the vitamins were discovered, if a child was sick with rickets, the doctors ______.A. let him/her eat milk, eggs and oily fishB. let him/her take some medicineC. let him/her drink much water and take a restD. didn?t know what to do48.The girl became worse and worse because ______.A. the doctor took blood from her bodyB. the doctor didn?t find a correct way to cure herC. the disease couldn?t be curedD. the doctor only used a common medicine49.According to the girl?s story, we can see ______.A. the peel of the apple can cure lots of diseasesB. as long as we often eat apples, we can?t suffer from diseasesC. vitamin C can cure scurryD. people can cure their own diseases without doctors50.Each person needs to eat a variety of different kinds of food ______.A. because they contain a lot of vitamins and can build up his healthB. in order to raise his living standardC. because of their different kinds of sweet smellD. though he is poor nowPassage 4Mr. Richards was quite good at shooting with a rifle, and he had taken part in several competitions in his small town. He had never actually won a prize, but each time he had done well, and once he had come fourth.Then he had to go to a big city on business for a month, and as he had nothing much to do in the evenings there, he joined the local rifle club, and spent several pleasant evenings shooting there.The rifle club had a very good team, which used to take part in a lot of important shooting competitions. One of these took place while Mr. Richards was with them, and of course he went to see it. But one of the members of the club?s team suddenly fell ill just before the match, and the captain had to choose somebody else to take his place in a hurry. He had heard that Mr. Richards had taken part in several competitions already, and hehad seen for himself at the club that, although he was not really up to the standard of the club?s first team, he was quite a good shot. He therefore invited him to take the sick?s place.Mr. Richards felt greatly honored to be asked to shoot for such a good team, but he also felt very nervous, because he was afraid of making a fool of himself and letting down his team.In fact, he was so nervous that he could not keep his hands from trembling while he was shooting, with the result that he did very badly in the competition. When he took his score card to his captain, he said, “After seeing my score, I feel like going outside and shooting myself.”The captain looked at the card for a few seconds and then said, “Well, you had better take two bullets with you if you do that.”51.Which of the following statements is true?A. Mr. Richards was not very skillful at shooting.B. Mr. Richards had won a prize once in a shooting competition.C. Mr. Richards had taken part in quite a few shooting competitions.D. Some of the team members in the club are not good at shooting, either.52.Why did Mr. Richards join the local rifle club when he went to a big city on business?A. Because he wanted to win a prize in shooting competitions.B. Because he didn?t have much to do in the evenings.C. Because he liked meeting people.D. Because he wanted to share his experiences with others.53.Why was Mr. Richards chosen to take the sick?s place?A. Because he had won shooting prizes.B. Because he had taken some competitions and was not a bad shot.C. Because he was as good a shot as any member of the club?s first team.D. Because the captain was sure that Mr. Richards would do well in the competition.54.Which of the following is true about Mr. Richards? shooting?A. He was nervous, but he managed to shoot well.B. He missed his target.C. He did badly because he was sick.D. His hands were trembling, so he couldn?t shoot w ell.55.What did the captain mean by saying “you had better take two bullets with you if you dothat??A. He was giving Mr. Richards suggestions.B.
