Section ADirections:In this section, you will hear ten short conversations. At the end of each conversation, a question will be asked about what was said. Each conversation and question will be read only once. After each question there will be a pause. During the pause, you must read the four choices marked A, B, C and D, and decide which is the best answer. Then mark the corresponding letter on the Answer Sheet with a single line through the center.Section BDirections:In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A) , B) , C) and D). Then mark the corresponding letter on Answer Sheet with a single line through the center.Passage onePassage twoPassage threeDirections: There are three passages for this task. The passages are followed by some questions. For each of them there are four choices marked A, B, C, and D. You should decide on the best answer and mark the corresponding letter on the answer sheet with a single line through the center.Passage OneQuestions 21 to 25 are based on the following passage:Several commentators and scientists have suggested that it might in some cases be ethically acceptable to clone existing people. One possibility is generating a replacement for a dying relative. All such possibilities, however, raise the concern that the clone would be treated as less than a complete inddividual, because he or she would likely be subjected to limitation and expectation based on the family’s knowledge of the genetic “twin.” Those expectations might be false, because human personality is only partly determined by genes. The clone of an extrovert(性格外向的人) could have a quite different way of behavior. Clones of athletes, movie stars, entrepreneurs or scientists might well choose different careers because of chance events in early life.Some people have also put forward the notion that couples in which one member is infertile might choose to make a copy of one or the other partner. But society ought to be concerned that a couple might not treat naturally a child who is a copy of just one of them. Because other methods are available for the treatment of all known types of infertility, conventional therapeutic avenues seem more appropriate. None of the suggested uses of cloning for making copies of existing people is ehically acceptable to my way of thinking, because they are not in the interests of the resulting child. It should go without saying that I am strongly opposed to allowing cloned human embryos to develop so that they can be tissue donors.It nonetheless seems clear that cloning from cultured cells will offer important medical opportunities. Predictions about new technologies are often wrong: societal attitudes change; unexpected developments occur. Time will tell. But biomedical researchers looking into the potential of cloning now have plenty to do.21. What is the author’s concern about cloing an existing person?A. The clone created will have one defect or another.B. The clone created will be mistreated.C. The clone created is unlikely to fulfill your expectations.D. The clone created is ethically unacceptable.22. It can be inferred from the text that a clone will _____.A. choose the same career as the person it is created fromB. behave in the same way as the person it is created fromC. share the same characteristics with the person it is created fromD. be partially similar in personality to the person it is created from23. According to the passage, one’s personality is determined by______.A. their genesB. the environment they live inC. both their genes and the environment they live inD. neither their genes nor the environment they live in.24. In the author’s view, which of the following uses of cloning is justifiable?A. To replace a lost relative.B. To help childrenless couples to have a baby.C. To develop tissue donors.D. To culture cells for medical purposes.25. What is autor’s attitude towards cloning technology?A. It should be condemned.B.It has medical potential for scientists to explore.C. It should wait till people’s views change.D. It was unethical from the very beginning.Passage 2Questions 26 to 30 are based on the following passage:The interview is an important event in the job-hunting process, because the 20 or 30 minutes you spend with the interviewer may determine whether or not you get the particular job you want. Therefore, it is important to remember that you objective during the interview may differ from the objective of the potential employer. You want to make yourself stand out as a whole person who has personal strength, is well qualified, and should be considered the right person for the job. It is encouraging to know that the interviewer’s task is not to embarrass you or to trip you up, but to hire the right person for the job.Remember, job hunting is very competitive. Anything you can do to enhance your interciew techniques will be to your advantage. The following suggestions may help you land the most important job.Your goal in this interview is to make sure your good points get across. The interviewer won’t know them unless you point them out, so try to do this in a factual and sincere manner.Do not make slighting references to former employers or professors. If you have been fired from a job and the interviewer asks about it, be frank in you answer.Show the inerviewer that you are interested in the company by asking relevant questions. Ask about responsibilities, working conditions, promotion opportunities and fringe benefits(附加福利) of the job you are interviewing for.If at some point you decide the interview is not going well, do not let your discouragement show. You have nothing to lose by continuing a show of confidence, and you may have much to gain. It may be real, or it may be a test to see how you react to adverse conditions.Some interviers may bring up salary early in the interview. At this time, you may indicate thatyou are more interested in a job where ou can prove yourself than a specific salary. This politely passes the question back to the interviewer. If the interviewer continues to press, give him a range or suggest the going rate for a particular job. If possible, you should negotiate for salary for salary after you have been offered a job and when you are ready to complete the paperwork.26. To get the job you want, during the interview you should .A. avoid the interviewer’s questions that are designed to trip you upB. remember that you are the best qualified candidateC. make yourself stand out as the right person for the jobD. keep in mind that it determines whether or not you get the particular job you want.27. If you did not ger along with your former employee, you .A. should tell the interviewer frankllyB. should not speak ill of himC. should refer to him in a factual mannerD. should never mention it28. When you find the interview is not going well you should ______.A. keep up your comfidenceB. bring it to an end as soon as possibleC. tell your interviewer how you react to adverse conditionsD. tell yourself you have much to gain and nothing to lose29. The best time to discuss your salary is .A. when you have been offered the jobB. at the end of the interviewC. after you have completed the paperworkD. when the interviewer brings this matter up30.The most important thing to do during an interview is .A. to make your strength understoodB. to show your intense interest in the job you are applying forC. to be frank and sincereD. to be natural and confidentPassage 3Questions 31 to 35 are based on the following passage:In traditional education, the teacher may feel that the students are not very grown up. Usually, teacher are older than students, and teachers feel that students are young and do not know very much about the world. The teachers feel that they must tell the students what to do most of the time, and that they must make the students study specific things. In open education, the teacher’s feelings are very different. These teachers feel that the students are individuals first, and students second. They expect the students to be responsible for the things that they do. The teacher allows the students to decide what they want to do, and does not make them study specific subjects ofthings. The teacher lets them decide what to study and how much to study.The second part of the idea of open education has something to do with what the teacher does in the classroom. In the traditional classroom, the students are told what to do. There is a list of things that the students must do to finish the class. There are rules made by the teacher that the students must follow, even if the students see no reason for the rules. In open education, the teacher allows the students to choose what to do. There are no specific things for the students to do. There are no traditional rules made by the teacher. The students are allowed to discover subjects in the open classroom instead of being made to study them.There are some very good things about open education. This way of teaching allows the students to grow as people. And to develop their own interests in many subjects. Open education allows students to be responsible for their own education. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules.But many students will not do well in an open classroom. They will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students.So for some of the good points and bad points of open education have been explained. The writer thinks that open education is a good idea, but only in theory. What do you think?31. One of the good points of open education is that .A. students may grow as peopleB. students all like itC. all the students will do wellD. some students have a problem getting used it32. Some students dislike open education because .A. they may have a problem greeting used itB. they are grown-upsC. they may study, or talk or do nothing at allD. they worry about the rules33. The writer thinks that open education is .A. better than traditional educationB. worse than traditional educationC. a good idea only in practiceD. a good idea only in theory34. The students are supposed to in open education.A. study specific thingsB. follow the rulesC. worry about gradesD. decide what to study35. In traditional education, the teacher may feel thatA. the students are not very grown-upB. the students don’t know very much about the worldC. they must make the students study specific thingsD. All of above.Part III Vocabulary (15%)Directions:There are 30 incomplete sentences in this part. For each sentence there are four choices marked A), B), C) and D).
