Most people in Britain live in houses _17_ flats, and many people own their homes. This means that they can make them individual; they can _18_ them and change them in any way they _19_ . In a crowded city the individual knows that he or she has a private space which is _20_ for himself of herself and for _21_ friends. People usually like to _22_ their space. Are you sitting now in your home or in a library or on a beach or a train? If you are on the beach you may have spread your _23_ around you; on the train you may have _24_ your coat or small bag on the seat beside you; in a library you may have one _25_ or chair which is your own.

One expert points out that the percentage(比率) of native English speakers is declining(降低) globally while the languages of other rapidly growing regions are being spoken by increasing numbers of people. But English will continue to remain widespread and important.However, British language scholar David Graddol says English will probably drop in dominance(主导) by the middle of this century to rank, after Chinese, about equally with Arabic, Hindi, and Urdu. “The number of people speaking English as a first language continues to rise, but it isnt rising nearly as fast as the numbers of many other languages around the world, simply because the main population group has been largely in the less developed countries where languages other than English have been spoken,” he says.In a recent article in the journal Science, Mr. Graddol noted that three languages that are not near the top of the list of the most widely spoken now might be there soon. These are Bengali, Tamil, and Malay, spoken in south and Southeast Asia.David Crystal, the author of the Cambridge Encyclopedia of the English Language, says about 1.5 billion of the worlds six billion people speak it as a second tongue compared to the 400 million native speakers. But another expert on the English language says Mr. Graddol underestimates (低估) the future of its dominance. “Nobody quite knows whats going to happen because no language has been in this position before. But all the evidence (证据) suggests that the English language snowball is rolling down a hill and is getting faster,” he said.36. In David Graddols opinion, English will _.A. remain widespread and importantB. be more important than any other language C. lose its dominant positionD. die away in the near future37. The underlined sentence in the last paragraph implies that _.A. snowballs will roll down faster than language ballsB. the English language snowball is rolling down faster than any time in the pastC. English language will soon drop in dominanceD. more and more language users will choose English38. How many experts does the passage mention who express their ideas about the future of English?A. 2. B. 3. C. 4. D. 5.39. According to David Graddol, which of the following will possibly be one of the languages that will be mostwidely spoken?A. Malay. B. Arabic. C. Urdu. D. German.40. What should be the best title for the passage?A. English Remaining the Dominant PositionB. The Future of English? Who Knows?C. Opinions from Different ExpertsD. The English Language Snowball Rolling DownBLanguage learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises.Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these cant be said to show the babys intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation（模仿）leads on to deliberate（有意的）imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.41. Before children start speaking_.A. they need equal amount of listeningB. they need different amounts of listeningC. they are all eager to cooperate with the adults by obeying spoken instructionsD. they cant understand and obey the adults oral instructions42. Children who start speaking late _.A. may have problems with their listeningB. probably do not hear enough language spoken around themC. usually pay close attention to what they hearD. often take a long time in learning to listen properly43. A babys first noises are _.A. an expression of his moods and feelingsB. an early form of languageC. a sign that he means to tell you somethingD. an imitation of the speech of adults44. The problem of deciding at what point a babys imitations can be considered as speech_.A. is important because words have different meanings for different peopleB .is not especially important because the changeover takes place graduallyC. is one that should be properly understood because the meaning of words changes with ageD. is one that should be completely ignored（忽略）because childrens use of words is often meaningless45. The speaker implies_.A. parents can never hope to teach their children new soundsB. children no longer imitate people after they begin to speakC. children who are good at imitating learn new words more quicklyD. even after they have learnt to speak, children still enjoy imitatingAnswers:1-5 A B B A B 6-10 D C B B C 11-15 D C D C A16-20 B A C C A 21-25 D A A C B 26-30 B A D A D 31-35 B A C C A36-40 C D B A B 41-45 B D A B D
