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. This announcement will also appear in the next issue of the student newspaper.41.Specific schedule changes for which of the following facilities are listed in thisannouncement?A.

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. He was not that disappointed at Mr. Richards? score.C. He was very angry at seeing Mr. Richards? score.D. He was trying to make Mr. Richards less uneasy.Part III ClozeDirections: There are 20 blanks in each of the following passages. For each blank there are four choices marked A, B, C, and D.

东海郡中为于公生立祠，命曰“于公祠”。
东海有孝妇，无子少寡，养其姑甚谨，其姑欲嫁之，终不肯。
其姑告邻人之曰：“孝妇养我甚谨，我哀其无子，守寡日久，我老，久累丁壮奈何？”其后，母自经死。
母女告吏曰：“孝妇杀我母。
”吏捕孝妇，孝妇辞不杀姑，吏欲毒治，孝妇自诬服，具狱以上府。
于公以为养姑十年以孝闻，此不杀姑也。
太守不听，数争不能得，于是于公辞疾去吏。
太守竟杀孝妇，郡中枯旱三年。
后太守至，卜求其故，于公曰：“孝妇不当死，前太守强杀之，咎当在此。
”于是杀牛祭孝妇冢，太守以下自至焉，天立大雨，岁丰熟。
郡中以此益敬重于公。
于公筑治庐舍，谓匠人曰：“为我高门，我治狱未尝有所冤，我后世必有封者，令容高盖驷马车。
”及子，封为西平侯。
（《说苑·贵德》）1．对下列句中加点词语的解释不正确的一项是（）A．决狱平法，未尝有所冤狱冤狱：案件B．郡中离文法者文法：法令条文C．我老，久累丁壮奈何丁壮：年轻男子D．其后，母自经死自经：上吊2．下列各组句子中加点的词的意义和用法相同的一组是（）A．其父号曰“于公”，为县狱吏 B．其姑告邻人之曰旦曰飨士卒，为击破沛公军王之好乐甚，则齐其庶几乎C．于公以为养姑十年以孝闻 D．郡中离文法者不赂者以赂者丧先破秦入咸阳者王之3．下列句中的“姑”字与例句中的“姑”的意思相同的一项是（）例句：养其姑甚谨A．被驱遣，小姑如我长B．昨夜洞房停红烛，侍晓堂前拜舅姑C．公曰：“多行不义必自毙。

（1）我治狱未尝有所冤，我后世必有封者，令容高盖驷马车。
（2）吏欲毒治，孝妇自诬服，具狱以上府四、现代文阅读季羡林注定与北大、清华有缘。
他十九岁进清华，二十三岁毕业，四载寒窗，奠定了百年学问的基础。
1981年，他以古稀之身作《清华颂》，文中说：“在清华的四年生活，是我一生中最难忘、最愉快的四年。
在那时候，国家民族正处在危急存亡的紧急关头，清华园也不可能成为世外桃源。
但是园子内的生活始终是生气勃勃的，充满了活力的。
民主的气氛，科学的传统，始终占着主导的地位。
我同广大的清华校友一样，现在所以有一点点知识，难道不就是在清华园中打下的基础吗？离开清华以后，我当然也学习了不少的新知识，但是在每一个阶段，只要我感觉到学习有所收获，我立刻想到清华园，没有在那里打下的基础，所有这一切都是不可能的。
”1935年，季羡林得母校清华的栽培，赴德留学。
1946年回国，又承清华教授陈寅恪的引荐，进了北大。
季羡林执教北大，迄今已届六十年。
他对清华的依恋，已如前述。
那么，他对北大又是一番什么情思呢？1998年北大百年校庆，季羡林发表了一篇短文：《我看北大》，内中有对于这个问题的归纳。
他说：“北大的历史不是一百年，而是几千年。
因为，北大最初的名称是京师大学堂，而京师大学堂的前身则是国子监。
国子监已有一千多年的历史，其前身又是太学，则历史更长了。
从最古的太学起，中经国子监，一直到近代的大学，学生都有以天下为己任的抱负。
在近代史上，历次反抗邪恶势力的运动，几乎都是从北大开始。
这是历史事实，谁也否认不掉的。
五四运动是其中最著名的一次。
虽然名义上是提倡科学与民主，骨子里仍然是一场爱国运动。
”绕了这样一个大弯子，袖里藏的是什么样的乾坤呢？这就是我们期待的答案。
季羡林说：“我在北大这样一所肩负着传承中华民族的优秀文化的、背后有悠久的爱国主义传统的学府，真正是如鱼得水，这才真正是我安身立命之地。
我曾在一篇文章中写过：我身上的优点不多，惟爱国不敢后人。
以我这样一个怀有深沉的爱国思想的人，竟能在有着悠久爱国主义传统的北大几乎度过了我的一生，我除了有幸福之感外，还有什么呢？还能何所求呢？”为季羡林作传，其间一个难题，就是如何把握传主的风格。
①你可以强调他的渊博，他的朴实，他的勤奋，他的温和而倔强，洒脱而严谨，清澈而幽默……但是，总觉得还差那么一点点，不够传神。
②直至有一天，读到他关于北大派和清华派的话题——他说：“北大和清华有没有差别呢？当然有的。
③据我个人的印象，在过去相当长的时间内，在国内和国际上的地位方面，在对中国教育、学术和文化的贡献方面，两校可以说是力量匹敌，无从轩轾。
④这是同一性。
但是，在双方的风范——我一时想不出更确切的词儿，姑且用之——方面，却并不相同。
如果允许我使用我在拙文《门外中外文论絮语》中提出来的文艺批评的话语的话，我想说，北大的风范可用人们对杜甫诗的评论‘沉郁顿挫’来概括，而对清华则可用杜甫对李白诗的评价‘清新俊逸’来概括。
