For questions 26-28, markY (for YES) if the statement agrees with the information given in the passage, N (for NO) if the statement contradicts the information given in the passage, or NG (for NOT GIVEN) if the statement is not given in the passage.For Questions 29 and 30, complete the sentences with the information given in the passage. English Around the WorldDo you speak English? That question is frequently asked in countries around the world. Although there are almost 3,000 languages, English is most universal. It is the official language in over 40 countries and the most used language in international business, science, and medicine.Even in countries where English is not the first language, a number of English words are used. No other language is borrowed from more often than English. For example, a French worker looks forward to le weekend. A Romanian shopper catches a ride on the trolleybus. A Chinese businessperson talks on the te le fung (telephone). Some Swedish schoolgirls have even started making the plural forms of words by adding –s, as in English, instead of the Swedish way of adding –ar, -or or –er.Hundreds of words borrowed from English can now be found in other languages, words such as soda, hotel, golf, tennis, jeans, O.K., baseball, and airport. Although many words are used just as they are, others are changed to make them more like the native language and therefore easier to say and remember. Thus a Japanese worker gets stuck in rushawa (rush-hour) traffic. A Spanish mother tells her child to put on her sueter (sweater), and a Ukrainian man goes to the barber for a herkot (haircut)English is everywhere. It is on signs, clothing, soft drinks, and household products around the world. In spite of the popularity of English words and phrases, however, they are not always welcome. Some people think that the use of English words is threatening the purity of their native language. The French started a commission to try to stop, and even give fines for the use of English words. Some countries have tried to eliminate English as their official language in order to save their native tongue.On the other hand, some people believe that English should be the international language. They give a number of reasons for this, such as the cost of translations and the misunderstanding that result from language differences. They believe that things would run more smoothly if everyone spoke the same language.“What would become of our many different cultures?‖ others argue. ―Certainly the world would be a much less interesting place,‖ they add. Indeed, there is serious concern on the part of language experts that many languages are disappearing. In some parts of the world, only a few people are left who can speak the native tongue. In Ireland, for example, there are only a few small areas where people speak Gaelic, the native Irish language. One expert says that half of the world’s languages are dying because children are no longer learning them.Languages have changed and disappeared throughout history. With progress, change is inevitable. Some things are worth preserving. Others are not. The difficulty is in deciding what is worth keeping. Because people have very strong feelings about the importance of their native language, we probably will not have a universal language in the near future. What is certain, however, is thatEnglish words will continue to pop up everywhere, from Taiwan to Timbuktu, whether some people like it or not.26. From the first paragraph, we know that at present English is used more widely in different fields than any other language in the world.27. Rushawa in Japan and sueter in Spanish show that some English words are changed so that they may be learned more quickly than the words in the native languages by the local people.28. In 1975, the French set up a commission to try to eliminate English as their official language.29. The author uses the example of Gaelic to illustrate that .30. At the end of the passage, the author draws a conclusion that . Section B Reading in Depth (10*2= 20 Points)Directions: In this section there are two passages each with five incomplete statements. Read each passage and complete the statements with one of the four given choices marked A, B, C, and D according to your comprehension. You should decide on the best choice and then write down the corresponding letter on the Answer Sheet.Passage OneQuestions 31 to 35 are based on the following passage.Part AIn 2001 the United Kingdom was hit again by foot-and-mouth disease, the first time since the 1960s, causing a national crisis. However, much of the panic and confusion was spread largely as a result of ignorance of the disease.Foot-and-mouth is a highly contagious (传染性的) disease found in Africa, South America, Asia, the Middle East and parts of Europe. It affects cloven-footed (偶蹄) domestic animals such as cows, pigs, sheep and goats, as well as wild animals like rats and deer and zoo animals such as elephants. Horses, however, cannot contract (感染) the disease.It is very rare for humans to catch the disease. Indeed, only one case has been recorded in Great Britain and that was in 1967.Part BFoot-and-mouth disease is insidious （潜伏的）and can be spread by direct and indirect contact with infected animal. The disease can be spread on the wind, and can be spread by people, equipment or vehicles which have been in contact with the disease.Although the authorities do not really know where this latest outbreak of the disease originated, it can enter a country in frozen meat imported from other countries where the disease is common. Unlike Mad Cow Disease (BSE) and the human equivalent CJD, foot-and-mouth has no implication （牵连）for the human food chain. Any meat, milk, cheese and other dairy products can be consumed quite safely.Part CIt seems that the only way to control the disease is to kill infected animals. There is no cure for the disease, and although adult animals normally recover in 2-3 weeks, they sadly remain carriers of the virus for up to two years.From the time the disease was first reported to the time the epidemic（流行）was officially declared over, one and a half million and more domestic animals were slaughtered and large areas of the countryside were closed to the public. These areas included parks, woods and forests, and various leisure attractions situated in the countryside.31. The main purpose of writing this passage is_______.A. to warn people of the danger of the diseaseB. to describe the disaster by the diseaseC. to share some of the facts about the diseaseD. to declare the success in control of the disease32. Foot-and-mouth disease is insidious because it is spread_______.A. by farmers and farm vehiclesB. in so many different waysC. by being carried in the airD. mainly by people who have been in contact with infected animals33. That foot-and-mouth disease is different from Mad Cow Disease mainly lies in that______.A. it affects the human food chainB. people cannot consume dairy productsC. it is found in frozen meatD. meat is still safe to eat34. The underlined word ―they‖ in Part C means ________.A. diseaseB. infected animalsC. adult animalsD. 2-3 weeks35. Which of the following is not true according to the passage?A. Horses cannot contract the foot-and-mouth disease.B. The record that humans caught the disease was first kept in 1967.C. Frozen meat imported from other countries can carry the disease.D. Animals infected can be cured in 2-3 weeks.Passage TwoQuestion 36 to 40 based on the following passage.In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill m the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early; a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe (严格的) over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child's own happiness.As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (说教), their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled.A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.36. Eagerly watching the child's acquisition of new skills, ___________.A. should be avoidedB. is universal among parentsC. sets up dangerous states of worry in the childD. will make the child lose interest in learning new things37. In the process of children's learning new skills, parents ________.A. should encourage them to read before they know the meaning of the words they readB. should expect a lot of the childrenC. should achieve a balance between pushing them too hard and leaving them on their ownD. should create as many learning opportunities as possible38. The second paragraph mainly tells us that ___________.A. parents should be strict with their childrenB. parental controls reflect only the values of the communityC. parental restrictions vary, and are not always for the benefit of the children aloneD. it's parents' and society's duty to control the children39. The word "precept" in Paragraph 3 probably means "___________".A. opinionB. punishmentC. behaviorD. instruction40. In terms of moral matters, parents should _________.A. follow the rules themselvesB. be aware of the huge difference between adults and childrenC. forbid their children to follow hook teachingsD. always ensure the security of their childrenPartⅢCloze (20*1= 20 points)Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C) and D). You should choose the ONE that best fits into the passage.

The reason may be easy to see: a shelf out of reach, a patch of ice on the misfortune—frustration, tiredness or just bad temper—that show what the accident really is, a sort of attack on oneself.Road accidents, for example, happen frequently after a family quarrel, and we all know people who are accident-prone, so often at odds with themselves and the world that they seem to cause accidents for themselves and others.By definition, an accident is something you can not predict or avoid, and the idea which used to be current, that the majority of road accidents are caused by a minority of criminally careless drivers, is not supported by insurance statistics. These show that most accidents involve ordinary motorists in a moment of carelessness or thoughtlessness.It is not always clear, either, what sort of conditions make people more likely to have an accident. For instance, the law requires all factories to take safety precautions and most companies have safety committees to make sure the regulations are observed, but still, every day in Britain, some fifty thousand men and women are injured from work due to accidents. These accidents are largely the result of human error or misjudgment—noise and fatigue, boredom or worries are possible factors which contribute to this. Doctors who work in factories have found that those who drink too much, usually people who have a high anxiety level, run three times the normal risk of accidents at work.6. The passage suggests that________.A. Accidents are usually caused by psychological factors.B. Accidents mostly result from slippery roads.C. Drinkers run three times the normal risk of accidents in factories.D. About 50 000people lose their lives at work in Britain every day.（阅读1）·第7 页共16 页7.

Factory accidents, unlike road accidents, are inevitable.D. Most road accidents are caused by just a few careless drivers.10. The best title for the passage would be __________.A. Accidents and AnxietyB. How to Deal with Accidents on Road and in FactoriesC. Human Factors in AccidentsD. How to Prevent Accidents on Road and in FactoriesPassage 3Questions 11 to 15 are based on the following passage.It is not often realized that women held a high place in southern European societies in the 10th and 11th centuries. As a wife, the woman was protected by the setting up of a dowry (嫁妆). Admittedly, the purpose of this was to protect her against the risk of desertion, but in reality its function in the social and family life of the time was much more important. The dowry was the wife’s right to receive a tenth of all her husband’s property. The wife had the right to with hold consent, in all transactions the husband would make, and more than just a right; the documents show that she enjoyed a real power of decision, equal to that of her husband. In no case do the documents indicate any degree of difference in the legal status of husband and wife.The wife shared in the manage ment of her husband’s personal property, but the opposite班级____________________学号____________________姓名____________________ ----------------------------------------密----------------------------------------封----------------------------------------线--------------------------------（阅读1）·第 9 页 共 16 页was not always true. Women seemed perfectly prepared to defend their own inheritance against husbands who tried to exceed their rights, and on occasion they showed a fine fighting spirit. A case in point is that of Maria Vivas. Having agreed with her husband Miro to sell a field she had inherited, for the needs of the household, she insisted on compensation. None being offered, she succeeded in dragging her husband to the scribe to have a contract duly drawn up assigning her a piece of land from Miro’s personal inheritance. The unfortunate husband was obliged to agree, as the contract says, “for the sake of peace.” Either through the dowry or through being hot-tempered, the wife knew how to win herself, with the context of the family, a powerful economic position.11. Originally, the purpose of a dowry is to ____.A. give a woman the right to receive all her husband’s propertyB. help a woman to enjoy a higher position in the familyC. protect a woman against the risk of desertionD. both A and C12. According to the passage, the legal status of the wife in marriage was ____. A. higher than that of a single woman B. higher than that of her husband C. lower than that of her husband D. the same as that of her husband13. Why does the author give us the example of Maria Vivas? ____A. To show that the wife shared in the management of her husband’s personal property.B. To show that the wife can defend her own inheritance.C. To prove that women have powerful position.D. To illustrate how women win her property.14.

The author’s attitude towards Maria Vivas is ____.A. sympatheticB. disapprovalC. indifferentD. objectivePassage 4Questions 16 to 20 are based on the following passage:Is language, like food, a basic human need? Judging from the result of the violent experiment by a German King, Frederick II, in the 13th century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.All the infants died before the first year. But clearly there was more than language deprivation here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected.Today no much violent deprivation exists as that by Frederick II. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to map up language rapidly. There are critical times, it seems, when children learn more readily. If these sensitive periods are neglected, the ideal time for acquiring language skills passes and they might never be learned so easily again.Linguists (语言学家) suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be of high IQ.Recent evidence suggests that an infant is born with the capacity to speak. What is special about Man’s brain compared wit h that of the monkey, is the complex system which enables achild to connect the sight and feel of , say, a teddy-bear(玩具熊)with the sound pattern “teddy-bear”.But speech has to be stimulated, and this depends on interaction between the mother and the ch ild, where the mother recognizes the signals in the child’s babbling(牙牙学语), grasping, crying, smiling, and responds to them. Insensitivity of the mother to these signals dulls the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child’s non-verbal signals is essential to the growth and development language.16. Frederick II’s experiment was violent because_________.A. he wanted to prove children are born with ability to speakB. he ignored the importance of mothering to the infantC. he was unkind to the nurseD. he wanted his nurses to say no mother tongue17. The reason some children are backward in speaking today that_________.A. their mothers do not respond to their attempts to speakB. their mothers are not intelligent enough to help themC. they do not listen carefully to their mothersD. their brains have to absorb too much language at once.18. By “critical times” in Paragraph 3 the author means__________.A. difficult periods in the child’s l ifeB. moments when the child becomes critical to its motherC. important stages in the child’s developmentD. times when mothers often neglect their children19. Which of the following in NOT implied in the passage?A. Ability to learn to speak a language is inborn in manB. Children do not need to be encouraged to learn to speakC. Early language starters are not necessarily highly intelligent（阅读1）·第11 页共16 页D. Most children learn their language in definite stages20. If the mother does not respond to her child’s signa ls_________.A. the child will never be able to speak properlyB. the child will stop giving out signalsC. the child will invent a language of his ownD. the child will make little effort to speakPassage 5Questions 21 to 25 are based on the following passage.Ask Steveland Morris and he’ll tell you that blindness is not necessarily disabling. Steveland was born prematurely and totally with sight in 1950. He became Steve Wonder ----- composer, singer, and pianist. The winner of ten Grammy awards, Stevie s widely acclaimed for his outstanding contributions to the music world.As a child, Stevie learned not to think about things he could not do, but to concentrate on the thing that he could do. His parents encouraged him to join his sighted brothers in as many activities as possible. They also help him to sharpen his sense of hearing, the sense upon which the visually disabled are so dependent.Because sound was so important to him, Stevie began at an early age to experiment with different kinds of sound. He would bang things together and then imitate the sound with his voice. Often relying on sound for entertainment , he sang, beat on toy drums, played a toy harmonica (口琴), and listened to the radio.Stevie soon graduated from toy instruments to real instruments. He first learned to play the drums. He then mastered the harmonica and the piano. He became a member of the junior church choir and the leading singer. In the evenings and on weekends, Stevie would play different instruments and sing popular rhythm and blues tunes on the front porches of neighbor’shomes.班级____________________学号____________________姓名____________________ ----------------------------------------密----------------------------------------封----------------------------------------线--------------------------------（阅读1）·第 13 页 共 16 页One of Stevie sessions was overhead by Ronnie White, a member of a popular singing group called The Miracles.
