Take Ted, for example. He prides himself on speaking his mind, and has something to say on everything. But his frankness is often extremely embarrassing. He is incapable of saying, “I thought that last advertising campaign had a lot of good ideas in it, but perhaps next time we could give the copy more vitality (活力) .” Instead, he could say, “That campaign was a disaster.

In stead he w3ill attempt to take part in the conversation, declaring, “You can talk in font of me. Henry and I don’t have many secrets, do we? ” Over the years Pergus has fallen behind his former equals.

The writer is taking the point of view of . A. a colleague B. people like Ted C. an employee D. a manager Passage 2 A lot of real businesses are focusing on the Internet as a way of building sales, but some people with nothing to sell are creating their own Web sites to announce wedding plans, show off pictures of their kids or just have communication.

绝密★启用前 江苏省2014年普通高校专转本选拔考试 英语试题卷 (非英语类专业) 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 One Questions 1 to 5 are based on the following passage. People and the sources of air pollution are found in the same place. This means that cities with large population have the biggest problem of dirty air. Air pollution is caused by many different things. A major source of air pollution is the gas fumes (烟尘) from cars. Another major source of dirty air is the burning of coal and oil for energy. This energy is needed to make electricity. Of course, much more electricity is used in the city than in the country. On the average, we throw away trash and garbage than years before. The burning of garbage leads to air pollution. Many major industries are also the cause of the dirty air in and around cities. The fumes from iron, steel, chemical, and petroleum production add particles (粉尘) to the air. The effects of air pollution range from mild headaches to death. The levels of pollution found in heavy traffic may cause headaches or loss of clear sight. Wherever coal and oil are used for fuel, fumes may kill trees and plants. In some of the larger cities, these fumes endanger the lives of human beings by leading to lung diseases and causing early deaths. 1. From the passage, we know that ______. A. air pollution is caused by electricity B. the cause of air pollution is not people C. air pollution is caused by many different sources D. headaches and death are not related to air pollution 2. What is stated in the passage? A. How cars produce fumes. B. Why so many people live in cities. C. What the causes and effects of air pollution are. D. How people in cities feel about polluted air. 3. Which of the following is NOT the cause of air pollution? A. Trucks. B. Headaches. C. Burning garbage. D. Burning coal and oil. 4.

Each passage is followed by four comprehension questions. Read the passage and answer the questions. Then mark your answer on the Answer Sheet. Passage One Questions 1 to 5 are based on the following passage: Animals react to the changing seasons with changes in mood and behavior and human beings are no exception. Most people find they eat and sleep slightly more in winter and dislike the dark mornings and short days. For some, however, symptoms (症状) are severe enough to damage their lives and to cause considerable stress. These people are suffering from SAD. The symptoms tend to start from around September each year lasting until April, but are at their worst in the darkest months. The standard figure says that around 2% of people in Northern Europe suffer badly, with many more (10%) putting up with milder symptoms. Across the world the incidence (发生率) increases with distance from the equator (赤道), except where there is snow on the ground, when it becomes less common. More women than men are found having SAD. Children and young people can also suffer from it. The problem stems from the lack of bright light in winter. Researchers have proved that bright light makes a difference to the brain chemistry, although the exact means by which sufferers are affected is not yet known. As the cause is lack of bright light, the treatment is to be in bright light every day by using a lightbox or a similar bright treatment. (Going to a brightly-lit climate, whether skiing or somewhere hot, is indeed a cure). The preferred level

2013年江苏省普通高校“专转本”英语统一考试试卷

2013年江苏省普通高校“专转本”英语统一考试试卷 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 One Questions 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 houses B.the causes of Mrs. Groeger’s death C.the longevity of people like Mrs. Groeger D.the image of cities in general 2.The second paragraph lists some ___________. A.disadvantage of walking B.occasions for walking in city life C.problems of city living https://www.doczj.com/doc/635979716.html,ments made by city people 3.To reach the third floor of a building, it would probably be most healthful ___________. A.to take the elevator B.to walk up the stairs C.to ride in a car D.to find an alternative walking 4.People who live in the country usually do more driving than walking because ___________. A.they don’t live near business areas B.they don’t need exercise C.they don’t like walking D.they can’t afford to take the bus

What do we mean by “culture?” Lately social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too. (81) When we speak of culture, we mean a way of life a group of people have in common. Culture includes the beliefs and attitudes we learn. It is the patterns of behavior that help people to live together. It is also the patterns of behavior that make one group of people different from another group. Our culture lets us make up for having lost out strength, claws, long teeth, and other defenses. Instead we use tools, cooperate with one another, and communicate with language. But these aspects of human behavior, or “culture,”can also be found in the lives of certain animals. Animals can make tools, for example. We used to think that the ability to use tools was the dividing line between human beings and other animals. Lately, however, we have found that this is not the case. Chimpanzees(非洲小猩猩) can not only use tools but actually make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So, it may be important for us to know that the line dividing us from animals is not as clear as we used to think. 1. Choose the statement that best expresses the main idea____. A. Chimpanzee can learn to use sign language to make sentences. B. Other animals can invent tools. C. Knowledge and communication are no longer signs of only human behavior. D. The line dividing human culture from animal culture is not as clear as we might think. 2. “Culture” refers to ____. A. book language of behavior we learn B. the patterns of behavior we learn C. traditional ideas D. people’s good habits 3. A chimpanzee’s use of tools means ____. A. animals are the same as human beings B. animals can be as clever as human beings C. the dividing line between culture and animal culture no longer exists D. animals may have a culture like our own 4. Which of the following statement is TRUE? A. The ability to use language separates human beings. B. We can be certain that animals have a culture too. C. Social scientists doubt if animals have a culture too. D. Some traditional ideas about the difference between human beings and animals may be wrong. 5.The first sentence of the second paragraph “Our culture lets us make up for having lost our strength, claws, long teeth, and other defenses” means ____. A. as a result of our culture, we have lost our strength, claws, long teeth, and other defenses B. our culture has enabled us even better though we have lost our strength, claws, long teeth, and other defenses C. our culture has brought back to us strength, claws, long teeth, and other defenses that we have lost D. our culture asks that we lose our strength, claws, long teeth, and other defenses which animals still have
