2013年江苏省普通高校“专转本”统一考试

2013年江苏省普通高校“专转本”统一考试Part I Reading Comprehension (共20小题,每小题2分,共40分)Directions: There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the center.Passage OneQuestions 1 to 5 are based on the following passage.When Mrs. Joseph Groeger died recently in Vienna, Austria, people asked the obvious question. “W hy did she live to be 107?” Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100. What was surprising was that the majority had lived most of their lives in cities. Although cities are often regarded as unhealthy places, city living provides benefits that country living may lack. One factor seems to be important to the longevity(长寿) of those interviewed.This factor is exercise. In the cities it is often faster to walk short distances than to wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have no elevators, and so people must climb stairs. City people can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no choice but to walk.On the other hand, those who live in the country and suburbs do not have to walk every day. In fact, the opposite is often true. To go to school, work, or almost anywhere else, they must ride in cars.1.The Vienna survey may help to explain __________.A.the complaints of people in apartment housesB.the causes of Mrs. Groeger’s deathC.the longevity of people like Mrs. GroegerD.the image of cities in general2.The second paragraph lists some ___________.A.disadvantage of walkingB.occasions for walking in city lifeC.problems of city livingments made by city people3.To reach the third floor of a building, it would probably be most healthful ___________.A.to take the elevatorB.to walk up the stairsC.to ride in a carD.to find an alternative walking4.People who live in the country usually do more driving than walking because ___________.A.they don’t live near business areasB.they don’t need exerciseC.they don’t like walkingD.they can’t afford to take the bus5.We can draw a conclusion from this passage that _________.A.air pollution is not seriousB.anyone can live to be 107C.country people should move to citiesD.walking is a healthful exercisePassage TwoQuestions 6 to 10 are based on the following passage.The Bedouin people, a tribe living in the deserts of Arabia and Northern African, think most highly of people who show loyalty. To them loyalty does not mean that one is devoted to a country, a place, or a leader. Loyalty means being faithful to one’s family and tribe.The Bedouin people are proud of their ancestors(祖先). They do not admire a hero from an ordinary or poor family as much as one who comes from an honored family. They especially respect those who have inherited(继承) a good family name and then have passed it on to their children.A man’s position among his people depends upon his ancestors, relatives, and fellow tribesmen. If they are honored, he is also honored. If they are disagreed, he, too, is disgraced. Therefore, one carefully guards the honor of his family and his tribe.A man can protect his family’s honors by being brave and generous and by giving protection to those who ask for it. He also guards it by carefully watching the women of his family.A Bedouin woman cannot bring honor to her family, but she can bring disgrace. Even if a woman only looks as if she has done something wrong, she may be killed. The honor of her family depends upon her virtue(美德).6. The best title for this passage can be __________.A. Life of the Bedouin PeopleB. Women’s Position in the Bedouin FamilyC. Bedouin People’s Idea of Loyalty and HonorD. How to Guard Honors7. The Bedouin people think most highly of one who is ______.A. devoted to his country and his leaderB. from an ordinary familyC. proud of his ancestor and relativesD. faithful to his family and tribe8. It is learned from the passage that ___________.A. a hero from an honored family is more admiredB. one can not live in the tribe without a good family nameC. all the Bedouin people are kind, brave and generousD. family traditions can never be passed to children9. The word “disgraced” (Para. 3) means “ __________”.A. disappearedB. disappointedC. dishonoredD. discouraged10. It is implied in the passage that the Bedouin women are __________.A. treated as the equals of menB. respected for what they doC. not interested in positionD. not respected as much as menPassage ThreeQuestions 11 to 15 are based on the following passage.Up until about 100 years ago, newspaper in the United States attracted only the most serious readers. They used no illustrations (插图) and the articles were about politics or business.Two men changed that---Joseph Pulitzer of the New York World and William Randolph Hearst of the New York Journal. Pulitzer bought the New York World in 1883. He changed it from a traditional newspaper into a very exciting one overnight. He added lots of illustrations and he told his reporters to write articles on every crime they could find. And they did. One woman reporter even pretended she was mad and was sent to a hospital. She then wrote many articles about the poor treatment of patients in those hospitals where madmen were kept. In 1895, Hearst came to New York from California. He wanted the Journal to be more exciting than the World. He also wanted it to be cheaper, so he lowered the price by a penny. Hearst attracted attention because his newspaper heading were bigger than any one else’s. He often said, “Big print makes big news.”Pulitzer and Hearst did anything they could to sell newspaper. For example, Hearst sent Frederic Remington, the famous illustrator, to draw pictures of the Spanish-American War. When he got there, he told Hearst that no fighting was going on. Hearst answered, “ You provide the pictures. I’ll provide the war.11. About a century ago, American newspaper carried news about __________.A. all kinds of exciting newsB. crimes and mad peopleC. the poor treatment of patientsD. serious matters only12. According to Paragraph 2, which of the following statements is TRUE?A. Pulitzer and a woman news reporter changed the world overnight.B. Pulitzer bought the Journal with the help of his reporter.C. A woman news reporter pretended to be mad.D. A woman reporter became mad and was sent to a hospital.13. Hearst attracted readers’ attention by ______________.A. using bigger headingsB. reporting big war newsC. raising the price of the newspaperD. reporting politics and business only14. __________ was asked to draw war pictures.A. HearstB. RemingtonC. PulitzerD. A woman reporter15. This passage tells us that ________.A. Pulitzer and Hearst were the most famous reporters of the United StatesB. newspaper owners sometimes hired mad men as their news reportersC. the world and the journal were not popular newspaper at that timeD. Pulitzer and Hearst used every possible means to win over each otherPassage FourQuestions 16 to 20 are based on the following passage.It is hard to imagine life without Arabic numbers(数字). No other number system ever invented has a simple way to write a number like 1984. In Roman numeral, it comes out like this MCMLXXXIV. Imagine how difficult it would be for a school pupil to remember it!The Arabs, however, call their numbers “Indian numerals”. This is probably because they got the original idea a long time ago from India. There were no printed newspapers or scientific magazine then, so mathematics traveled along the same routes that silk did, as businessmen sold and bought goods. The Arabs took the new numbers and made improvements that quickly led to advances in technology.The achievement of Arabic technology can be seen from a passage in a 10th-century book about an Arabic city:” The neighboring country showed the results of careful work in agriculture, trade, and industry. Rice and many other plants were grown in fields with water supplied by Arab engineers. The city included 900 public baths, stone-covered streets, fountains, and beautiful buildings.” At this time, London was a small town with dirty streets, and Berlin was a farming village. In fact, cities outside the Arab world did not reach the same level of social development until centuries later.16. This passage tells us that the Arabs were a people _______________.A. inventing Roman numeralsB. having advanced technology long agoC. growing corn and many other plants thenD. supplying other countries with colorful silk17. It takes much more efforts to ___________.A. learn Roman numerals than Arab numeralsB. introduce numerals through printed materialsC. make great use of silk roadsD. teach businessmen numerals18. The Arabs call their numerals “ Indian numerals” because _________.A. the numerals are mainly used in ChinaB. they copied numerals from IndiansC. Arabic numerals were first used by Indian businessmenD. they got some ideas about number from the ancient Indians19. According to the passage, the Arab people ___________.A. did business with the IndiansB. learned some ideas about business from IndiansC. built public baths in London in the 10th centuryD. traveled a long way to learn mathematics in Rome20. From a 10th-century book, we can learn that ___________.A. Berlin was formerly a dirty with sufficient rice and plantsB. London was under the rule of the Romans in the 10th centuryC. the Arab world was more advanced than other countries aroundD. London chiefly developed industry ten centuries agoPart II Vocabulary and Structure (共40小题,每小题1分,共40分)Directions: There are 40 incomplete sentences in this part.
