It is the address of the White House, the home of the president of the United States. Originally the White House was gray and was called the Presidential Palace. It was built from 1792 to 1800. at this time, the city of Washington itself was being built; it was to be the nation’s new capital city. George Washington, the first president, and Pierre Charles L’Enfant, a French engineer, chose the place for the new city. L’Enfant then planned they city. The president’s home was an important part of the plan. A contest was held to pick a design for the president’s home. An architect named James Hoban won. He designed a large three-story house of gray stone. President Washington never lived in the President Palace. The first president to live there was John Adams, the second president of the United States, and his wife Mrs. Adams did not really like hew new house.

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,灰浆) 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(肮脏)and disease and the spread crime. The city is tackling the situation energetically and enormous blocks of tenements(贫民住宅)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.

Then mark your answer on the Answer Sheet. Passage 1 Questions 1 to 5 are based on the following passage: Some years ago the captain of a ship was very interested in medicine. He always took medicine books to sea and liked to talk about different diseases. One day a lazy sailor on his ship pretended to be ill. He lay on his bunk (铺) and groaned as if he were very sick. The captain came to see him and was very pleased to have a patient to look after. He told the man to rest for a few days and made the other sailors do his work. Three days later another sailor pretended that he had something wrong with his chest. Once more the captain looked in his medical books and told “sick” man to have a rest. The other sailors were very angry because they had more work to do. The patients had the best food and laughed at their friends when the captain was not looking. At last the mate (船长副手) decided to cure the “sick” men. He mixed up some soap, soot (烟灰), glue (胶水) and other unpleasant things. Then he obtained permission from the captain to give his medicine to the “sick” men. When they tasted the medicine, they really did feel ill. It was so horrible that one of the patients jumped out of hi bunk, ran up on desk and climbed the highest mast on the ship. He did not want any more medicine. The mate told both of the men that they must take the medicine every half an hour, night and day. This soon cured them. They both said they felt better and wanted to start word again.

Passage 4 Questions 16 to 20 are based on the following passage: The new global satellite communications systems will offer three kinds service, which may overlap in many different kinds of receivers. VOICE. Satellite telephones will be able to make calls from anywhere on the Earth to anywhere else. That could make them especially useful to remote, third world villages (some of which already use stationary satellite telephones), explorers and disaster-relief teams. Today’s mobile telephones depend on earth-bound transmitters, where technical standards vary from country to country. So business travelers cannot use their mobile phones on international trips. Satellite telephones would make that possible. MESSAGING. Satellite massagers have the same global coverage as satellite telephones, but carry text alone, which could be useful for those with laptop computers. Equipped with a small screen like today’s papers, satellite massagers will also receive short messages. TRACKING. Voice and messaging systems will also tell their users where they are to within a few hundred meters. Combined with the messaging service, the location service could help rescue teams to find stranded adventurers, the police to find stolen cars, exporters to follow the progress of cargoes, and haulage companies to check that drivers are not detouring the pub. America’s military Global Positioning System (GPS) satellite will provide better positioning information to anyone who has a receiver for their signals, but GPS does not carry messages, so such a receiver cannot be used on its own for tracking or rescue. By the mid-1990s, GPS receivers will be able to tell people where they are to within 70 meters anywhere in the world, and to within a meter or so in areas where the service is supplemented by ground-based transmitter. 16. Global satellite communications systems will be useful to . A. laptop computer users B. remote villages C. disaster-relief teams D. all above 17. Satellite telephone will make . A. business travelers use mobile phones on international trips B. possible calls from anywhere on earth to anywhere else C. explorers happy D. all above 18. Which of the following is true? A. The positioning precision of the voice system is better than that of GPS. B. The positioning precision of GPS is Better than that of the voice system. C. The positioning precision of the messaging system is better than of GPS. D. The positioning precision of voice system is better than that of the messaging system. 19. What can we say about the new global satellite communications systems? A. They are widely used. B. They are very helpful. C. They are costly. D. Both A and B. 20. Which of the following may be the best title for the passage? A. Global Satellite Communications B. New Voice and Messaging System C. New Generation Satellite D. Always in Touch
