What does the future hold for the problem of housing? A good deal depends, of course, on the meaning of “future”. If one is thinking in terms of science fiction and the space age, it is at least possible to assume that man will have solved such trivial and earthly problems as housing. Writers of science fiction, from H.G. Wells onwards, have had little to say on the subject. They have conveyed the suggestion that men will live in great comfort, with every conceivable apparatus to make life smooth, healthy and easy, if not happy. But they have not said what his house will be made of. Perhaps some new building material, as yet unimagined, will have been discovered or invented at least. One may be certain that bricks and mortar(泥灰,灰漿) will long have gone out of fashion. But the problems of the next generation or two can more readily be imagined. Scientists have already pointed out that unless something is done either to restrict the world’s rapid growth in population or to discover and develop new sources of food (or both), millions of people will be dying of starvation or at the best suffering from underfeeding before this century is out. But nobody has yet worked out any plan for housing these growing populations. Admittedly the worst situations will occur in the hottest parts of the world, where housing can be light structure or in backward areas where standards are traditionally low. But even the minimum shelter requires materials of some kind and in the teeming, bulging towns the low-standard “housing” of flattened petrol cans and dirty canvas is far more wasteful of ground space than can be tolerated. Since the war, Hong Kong has suffered the kind of crisis which is likely to arise in many other places during the next generation. Literally millions of refugees arrived to swell the already growing population and emergency steps had to be taken rapidly to prevent squalor(骯臟)and disease and the spread crime. The city is tackling the situation energetically and enormous blocks of tenements(貧民住宅)are rising at an astonishing aped. But Hong Kong is only one small part of what will certainly become a vast problem and not merely a housing problem, because when population grows at this rate there are accompanying problems of education, transport, hospital services, drainage, water supply and so on. Not every area may give the same resources as Hong Kong to draw upon and the search for quicker and cheaper methods of construction must never cease. 1.What is the author’s opinion of housing problems in the first paragraph? A.They may be completely solved at sometime in the future. B.They are unimportant and easily dealt with. C.They will not be solved until a new building material has been discovered. D.They have been dealt with in specific detail in books describing the future. 2.The writer is sure that in the distant future ___. A.bricks and mortar will be replaced by some other building material. B.a new building material will have been invented. C.bricks and mortar will not be used by people who want their house to be fashionable. D.a new way of using bricks and mortar will have been discovered. 3.The writer believes that the biggest problem likely to confront the world before the end of the century ___. A.is difficult to foresee. B.will be how to feed the ever growing population. C.will be how to provide enough houses in the hottest parts of the world. D.is the question of finding enough ground space. 4.When the writer says that the worst situations will occur in the hottest parts of the world or in backward areas, he is referring to the fact that in these parts ___. A.standards of building are low. B.only minimum shelter will be possible. C.there is not enough ground space. D.the population growth will be the greatest. 5.Which of the following sentences best summarizes Paragraph 3? A.Hong Kong has faced a serious crisis caused by millions of refugees. B.Hong Kong has successfully dealt with the emergency caused by millions of refugees. C.Hong Kong’s crisis was not only a matter of housing but included a number of other problems of population growth. D.Many parts of the world may have to face the kind of problems encountered by Hong Kong and may find it much harder to deal with them.

The tourist trade is booming. With all this coming and going , you'd expect greater understanding o develop between the nations of the world. Not a bit of it ! Superb systems of communication by air, sea and land make it possible for us to visit each other's countries at a moderate cost. What was once the 'grand tour' , reserved for only the very rich , is now within everybody's grasp ? The package tour and chartered flights are not to be sneered at. Modern travelers enjoy a level of comfort which the lords and ladies on grand tours in the old days couldn't have dreamed of. But what's the sense of this mass exchange of populations if the nations of the world remain basically ignorant of each other? Many tourist organizations are directly responsible for this state of affairs. They deliberately set out to protect their clients from too much contact with the local population. The modern tourist leads a cosseted, sheltered life. He lives at international hotels , where he eats his international food and sips his international drink while he gazes at the natives from a distance. Conducted tours to places of interest are carefully censored. The tourist is allowed to see only what the organizers want him to see and no more. A strict schedule makes it impossible for the tourist to wander off on his own ; and anyway, language is always a barrier, so he is only too happy to be protected in this way. At its very worst , this leads to a new and hideous kind of colonization. The summer quarters of the inhabitants of the cite universitaire : are temporarily reestablished on the island of Corfu. Blackpool is recreated at Torremolinos where the traveler goes not to eat paella, but fish and chips. The sad thing about this situation is that it leads to the persistence of national stereotypes. We don't see the people of other nations as they really are, but as we have been brought up to believe they are. You can test this for yourself. Take five nationalities , say, French, German, English, American and Italian. Now in your mind, match them with these five adjectives : musical, amorous, cold, pedantic, native. Far from providing us with any insight into the national characteristics of the peoples just mentioned , these adjectives actually act as barriers. So when you set out on your travels, the only characteristics you notice are those which confirm your preconceptions. You come away with the highly unoriginal and inaccurate impression that , say,'Anglo-Saxons are hypocrites' of that 'Latin peoples shout a lot'. You only have to make a few foreign friends to understand how absurd and harmful national stereotypes are. But how can you make foreign friends when the tourist trade does its best to prevent you ? Carried to an extreme, stereotypes can be positively dangerous. Wild generalizations stir up racial hatred and blind us to the basic fact 〞how trite it sounds ! 每 That all people are human. We are all similar to each other and at the same time all unique. 1. The best title for this passage is [A] Tourism contributes nothing to increasing understanding between nations. [B] Tourism is tiresome. [C] Conducted tour is dull. [D] Tourism really does something to one's country. 2. What is the author's attitude toward tourism ? [A] apprehensive. [B]negative. [C] critical. [D] appreciative. 3. Which word in the following is the best to summarize Latin people shout a lot? [A] silent. [B] noisy. [C] lively. [D] active. 4. The purpose of the author's criticism is to point out [A] conducted tour is disappointing. [B]the way of touring should be changed. [C] when traveling , you notice characteristics which confirm preconception. [D] national stereotypes should be changed. 5. What is 'grand tour' now ? [A] moderate cost. [B]local sight-seeing is investigated by the tourist organization. [C] people enjoy the first-rate comforts. [D] everybody can enjoy the 'grand tour'
