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.

Passage 2 Questions 6 to 10 are based on the following passage: There are two kinds of memory: shot-term and long-term. Information in long-term memory can be remembered at a later time when it is needed. The information may be kept for days or weeks. However, information over and over. The following experiment shows how short-term memory has been studied. Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 college students. They represented all levels of ability in English: beginning, intermediate, and native-speaking students. To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered, each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Finally the subjects took a language proficiency test. Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning’s results suggest that beginning students hold the sound of words in their short-term memory, and advanced students hold the meaning of words in their short-term memory. 6. Henning made the experiment in order to study . A. how students remember English vocabulary by short-term memory B. how students learn English vocabulary C. how to develop students’ ability in English D. how long information in short-term memory is kept 7. Which of the following statements is TRUE according to the passage? A. Information in short-term memory is different from that in long-term memory. B. Long-term memory can be achieved only by training. C. It is easier to test short-term memory than long-term memory. D. Henning gave a separate test on vocabulary to his students. 8. From Henning’s result we can see that . A. beginners have difficulty distinguishing the pronunciation of words B. advanced students remember words by their meaning C. it is difficult to remember words that sound alike D. it is difficult to remember words that have the same meaning 9. The word “subjects” in the passage means . A. memory B. the theme of listening material C. a branch of knowledge studied D. the students experimented on

Passage 3 Questions 11 to 15 are based on the following passage: Unlike their American or European counterparts, car salesmen in Japan work hard to get a buyer. Instead of lying lazily around showrooms waiting for customers to drop by, many Japanese car salesmen still go out to get them. They walk wearily along the streets cars door-to-door. New customers are hunted with fruit and cakes on their birthdays. But life is getting tough, and not just because new-car sales are falling. With more Japanese women (who often control the household budget) going out to work, the salesmen increasingly find nobody at home when they call. That means another visit in the evening or the weekend. Then they face an extra problem: more people, especially the young, prefer to choose a new car from a showroom where they can compare different models. Even as late as the mid-1980s some 90% of new cars were sold door-to-door. In some rural areas most new cars are still sold this way. But in the big cities more than half the new cars are now sold from showrooms. Although investing in showrooms is expensive because of the high cost of Japanese land, dealers have little choice. A labor shortage and higher among Japan’s workforce are making it difficult to hire door-to-door salesmen. Most of a Japanese car salesman’s working day is spent doing favors for customers, like arranging insurance or picking up vehicles for servicing, rather than actually selling. Japan’s doorstep car salesmen are not about to vanish. The personal service they provide is so deep-rooted in Japan that they are likely to operate alongside the glittering new showrooms. The two systems even complement each other. What increasingly happens is that the showroom attracts the interest of a potential buyer, giving the footsore salesmen a firm lead to follow up with a home visit. 11. Japanese car sales usually do not wait at showrooms for customers to drop by; instead, . A. they sell cars door-to-door B. they buy presents for their customers C. they enjoy themselves in recreation centers D. they go out to do market researches 12. Implied but stated: the competition in car market is . A. light B. moderate C. fierce D. unfair 13. Young people like to buy a new car . A. at home B. from a showroom C. made in the U.S.A. D. made in Japan 14. The squadron of Japanese car salesmen is reducing because of . A. a labor shortage B. higher expectations among Japan’s workforce C. high cost land D. both A and B 15. Japanese car salesmen to their customers many favors such as . A. showing them around in an exhibition B. arranging insurance C. paying them a visit on weekends D. selling ole cars for them

Passage 2 Questions 6 to 10 are based on the following passage: When aluminum was first produced about a hundred and fifty years ago, it was so difficult to separate form the ores in which it was found that its price was higher than that of gold. The price remained high until a new process was discovered for refining the metal with the aid of electricity approximately three quarters of a century later. The new method was so much cheaper that aluminum because practical for many purposes, one of which was making pots and pans. Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with other metals, scientists have been able to produce a variety of alloys, some of which have the strength of steel but weigh only one third as much. Today, the uses of aluminum are innumerable. Perhaps its most important use is in transportation. Aluminum is found in the engine of automobiles, in the hulls of boats. It is also used in many parts of airplanes. In fact, the huge “airbus” planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the amount of fuel needed to move them, Aluminum is also being used extensively in the building industry in some countries. Since aluminum is such a versatile (多用的) metal, it is fortunate that bauxite (铝土矿), which is one of its chief sources, is also one of the earth’s most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be found for this versatile metal. 6.
