江苏专转本英语真题及答案

江苏省2012 年普通高校专转本统一英 语考试 第一卷(共100 分) Part I Reading Comprehension(共20 题,每题 2 分,共40 分) Passage One Questions 1 to 5 are based on the following passage. American researchers have developed a technique that may become an important tool in fighting AIDS. The technique stops the AIDS virus from attacking its target-cells in the body's defense system. When AIDS virus enters the blood, it searches for blood cells called T4 lymphocytes (淋巴细胞). The virus connects to the outside of T4 lymphocytes, then forces its way inside. There it directs the cells' genetic (基因的)material to produce copies of the AIDS virus. This is how AIDS spreads.Researchers think they may be able to stop AIDS from spreading by preventing virus from connecting to T4 cells. When AIDS virus finds a T4 cell, it actually connects to a part of the cell called CD4 protein.Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood. This way the AIDS virus will connect to the cloned protein instead of the real ones. Scientists use the genetic engineering methods to make the clones. Normally a CD4 protein remains on the T4 cell at all times. The AIDS virus must go to it.In a new technique, however, the cloned CD4 protein is not connected to a cell. It floats freely, so many more can be put into the blood to keep the AIDS virus away from real CD4 proteins on T4 cells. One report says the AIDS virus connects to the cloned proteins j ust as effectively as to real protein. That report was based on tests with blood cells grown in labs. The technique is just now beginning t o be tested in animals. If successful, it may be tested in humans within a year. 1. The new technique can ________. A. cure AIDS B. kill the AIDS virus C. prevent the AIDS virus from spreading D. produce new medicines for AIDS 2. When the AIDS virus enters the blood, it is reproduced by ________. A. the inside of the virus itself B. any blood cells in the body C. the CD4 protein D. the genetic material of T4 cells 3 The AIDS virus connects to cloned proteins instead of to the real ones because ________. A. the cloned proteins stay on the T4 cells B. the cloned proteins can float freely in the blood C. it connects to cloned proteins more effectively than to the real ones D. the cloned proteins are made by genetic engineering methods 4. Which of the following statements is NOT true? A. The new technique has been tested in labs. B. The new technique is being tested in animals. C. The new technique may be tested in humans. D. The new technique is now under clinical test. 5 Which of the following could be the best title of this passage? A. AIDS---a Fatal Disease. B. A New Technique in fighting AIDS. C. A Report on the Spread of AIDS Virus. D. The Technique of Cloned CD4 Protein. Passage TWO Questions 6 to 10 are based on the following passage. During the early ears of last century, wheat was seen as the very lifeblood of Western Canada.

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 1~5 are besed on the following passage. Young Koreans are beginning to do it alone when it comes to finding a partner, though matchmaking is still the most common way for boys to meet girls. Professional matchmakers can make thousands of American dollars by introducing suitable marriage partners to each other, but partners also play a role in the process during which young Koreans meet. In Confucius Korea, where marriage is regarded as more of a business contract than a sacred thing, the scene of the first meeting is repeated hundreds of times a day in coffee shops in the main hotels around Seoul. The business of continuing the family lineage (血统)and keeping the blooding pure is often too important to be left to romance and chance encounters. Often, the girl will work out a system of secret signals with her mother, from which her parents can tell if she is interested. For example, if the girl orders a coffee it might mean that she wants her parents to leave her alone with the boy, while a milk shows that she wants them to stay. Sometimes the matchmaking is not always so formal, with the introduction being made by friends. But whether through friends or families, there is hardly a Korean man in the country who has not gone through this process --- sometimes six or seven times. 1. The word “matchmaking” in the passage means ____. A. a very formal ritual(仪式)attended by boys and girls B. introducing boys and girls to know each other for the purpose of marriage C. producing matches to make a fire or light a cigarette D. arranging games between men and women 2. The fact that the first meeting is repeated again and again in coffee shops in the main hotels suggests that ____. A. Koreans like drinking coffee in coffee shops very much B. men and women want to meet as many times as possible C. they are busy with communicating with different people D. marriage is seen as a business contract instead of something sacred

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 your answer by blackening the corresponding letter on the Answer Sheet . Passage One Questions 1 to 5 based on the following passage . We use both words and gestures to express our feelings ,but the problem is that these words and gestures can be understood in different ways . It is true that a smile means the same thing in any language . So does laughter or crying . There are also a number of striking similarities in the way different animals show the same feelings . Dogs , tigers and humans , for example , often show their teeth when they are angry . This is probably because they are born with those behavior patterns . Fear is another emotion that is shown in much the same way all over the world . In Chinese and English literature , a phrase like “he went pale and began to tremble”suggests that the man is either very afraid or deeply shocked . However , “he opened his eyes wide ” is used to suggest anger in Chinese whereas in English it means surprise . In Chinese surprise can be described in a phrase like “they stretched out their tongues ”. Sticking out your tongue in English is an insulting gesture or expresses strong dislike . Even in the same culture , people differ in the ability to understand and express feelings Experiments in America have shown that women are usually better than men at recognizing fear ,anger love and happiness on people’s faces . Other studies show that older people usually find it easier to recognize or understand body language than younger people do . to the passage , _________.
