Passage 3 Questions 11 to 15 are based on the following passage: The idea of a special day to honor mothers was first put forward in America in 1907. two years later a woman, Mrs. John Bruce Dodd, in the state of Washington proposed a similar day to honor the head of the family—the father. Her mother died when she was very young, and her father brought her up. She loved her father very much. In response to Mrs. Dodd’s idea that same year—1909, the state governor of Washington proclaimed (宣布) the third Sunday in June Father’s Day. The idea was officially approved by President Woodrow Wilson in 1916. in 1924, President Calvin Coolidge recommended national observance of the occasion “to establish more intimate (亲密) relations between fathers and their children, and to impress upon fathers the full measure of their obligations.” The red or white rose is recognized as the official Father’s Day flower. Father’s Day took longer to establish on a national scale than Mother’s Day, but as the idea grained popularity, tradesmen and manufacturers began to see the commercial possibilities. They encouraged sons and daughters to honor their fathers with small thank-you presents, such as a tie or pair of socks, as well as by sending greeting cards. During the Second World War, American servicemen stationed in Britain began to request Father’s Day greeting cards to send home. This generated a response with British card publishers. Though at first the British public was slow to accept this rather artificial day, it’s now well celebrated in Britain on the third Sunday in June in much the same way as in America. Father’s Day seems to be much less important as occasion than the Mother’s Day. Not many of the children offer their fathers some presents. But the American fathers still think they are much better fated than the fathers of many other countries, who have not even a day for their sake in name only. 11. When did Father’s Day officially begin to have national popularity? A. 1907 B. 1909 C. 1916 D. 1924 12. Who first started the idea of holding the Father’s Day? A. Mrs. John Bruce Dodd B. Mrs. John Bruce’s Mother C. The government of Washington. D. Some businessmen. 13. What flower will be popular on Father’s Day? A. Lily B. Water Lily C. Red rose or white rose D. Sunflower. 14. Which statement is true, a according to this passage? A. It took even longer for Mother’s Day to gain national popularity. B. The businessmen helped to make Father’s Day popular. C. Father’s Day is only celebrated in America. D. Father’s Day is only a trick of the businessmen to make money. 15. What was the first reaction of the British publishing towards Father’s Day? A. They thought highly of it and accepted it at once. B. They just accepted it at once without any hesitation. C. They just thought it a joke. D. They thought it was too artificial and took a long time to accept.

Part I Reading Comprehension Directions: In this part there are four passages. Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet. Passage 1 Questions 1 to 5 are based on the following passage: Ask three people to look the same window at a busy street corner and tell you what they see. Chances are you will receive three different answers. Each person sees the same scene, but each perceives something different about it. Perceiving goes on in our minds. Of the three people who look out the window, one may say that he sees a policeman giving a motorist a ticket. Another may say that he sees a rush-hour traffic jam at the intersection. The third may tell you that he sees a woman trying to cross the street with four children in tow. For perception is the mind’s interpretation of what the senses—in this case our eyes—tell us. Many psychologists today are working to try to determine just how a person experiences or perceives the world around him. Using a scientific approach, these psychologists set up experiments in which they can control all of the factors. By measuring and charting the results of many experiments, they are trying to find out what makes different people perceive totally different things about the same scene. 1. Seeing and perceiving are . A. the same action B. two separate actions C. two actions carried on entirely by eyes D. several actions that take place at different times 2. Perceiving is an action that takes place . A. in our eyes B. only when we think very hard about something C. only under the direction of a psychologist D. in every person’s mind 3. People perceive different things about the same scene because . A. they see different things B. some have better eyesight C. they cannot agree about things D. none of these 4. Which of the following is implied but not stated in the passage? A. Psychologists do not yet know people see. B. The experiments in which all factors are controlled are better. C. The study of perception is going on now. D. Perception does not involve psychological factors. 5. The best title for this selection is . A. How We See B. Learning about Our Minds through Science C. What Psychologists Perceive D. How to Because an Experimental Psychologist

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.
