 Section A
  11.M:How many students passed the College English Test last term?
  W:Well,let me see.1016 students took the exam,but half of them failed.
  Q:How many students did the woman believe had passed the exam?
  12.W:Is Aunt Mary in? I’ve got something important to tell her.
  M:Sorry,mother has gone shopping.She won’t be back until lunch time.
  Q:What is the relationship between the two speakers?
  13.M:Susan isn’t here yet.Did you forget to invite her?
  W:She was ready to come.but then changed her mind.
  Q:Why isn’t Susan present?
  14.W:Why are you just standing outside instead of going in?
  M:I have tried all my keys in the lock,but it won’t open.
  Q:Why didn’t the man go in?
  15.M:You don’t look a day over thirty.
  W:Really? In fact.I’m thirty-five.
  Q:How does the woman feel about the man’s remark?
  16.M:Did your sister like her new car?
  W:She thought it was too noisy.and something got wrong with the tyres;but my father believed it was quite a good Car.
  Q:What did the woman’s father think of the new car?
  17.W:Fasten your belts.and we will take off soon.
  M:But would you like to tell me how to fasten it?
  Q:Where did the conversation take place?
  18. M: Are you going to the concert tonight?
  W: No, I promised to baby-sit for my neighbors while they have a meeting.
  Q: What will the woman do tonight?
  Now you’ll hear two long conversations.
  Conversation One
  W: Excuse me, I’ve been using this old book for a research project and I notice that a lot of pages are turning brown and becoming brittle.
  M: Yes. Unfortunately, that’s a common problem with books made from wood pulp.
  W: I suppose that to make paper from wood you have to add a lot of chemicals and acids to make it turn white.
  M: Exactly, and it’s the acid that eventually eats away the paper.
  W: Oh, that actually makes sense, but this book’s not even 75 years old and I’ve seen books in museum that are hundreds of years old and they’re in free condition.
  M: Well, you see, books have been made from Wood pulp only since the 1850s, before that they were made from materials mostly animals’ skins, and no chemicals were added.
  W: It’s a shame those older wood pulp books are going to fall apart some day. Is there anything that can be done to preserve them?
  M: En, currently the only way to stop the books from decaying is to remove the binding and treat each page individually to remove the acid.
  W: That doesn’t sound very economical.
  M: No, it isn’t. It’s not practical to treat a large number of books with this process, so we only try to rescue the most valuable edition books in our collection.
  W: Well, thanks for the explanation. I’d better get back to my project.
  M: Good luck and I hope the old book will hold long enough for you to finish it.
  Questions 19 to 22 are based on the conversation you have just heard.
  19. What are the speakers mainly discussing?
  20. According to the man, why do modem books decay?
  21. What does the man say about books published before 1850?
  22. What will the woman probably do next?
  Conversation Two
  M: Do you want to go to the cinema with us on Saturday?
  W: Thanks, but I have to study for my research project. I’m taking that same anthropology course you took with Professor Gray.
  M: The one on ethnographic interviewing? Oh, good! I’m sure you’ll get a lot out of it.
  W: I have to admit the word "ethnography" scared me a little at first. It seems so technical. But then when she explained that it’s what anthropologists do, you know, how they investigate and record aspects of a culture, it didn’t seem so intimidating!
  M: Yeah, it’s a part of the field work anthropologists conduct and it’s good to start doing that now before you become a graduate student and have to conduct large projects yourself. Who are you going to interview?
  W: You know the publishing office where I used to work? Vivian, the woman I worked for, has been a manager there for over 30 years and seen a lot of changes in the industry. I thought I’d start out by interviewing her about how the people in the office interact with each other and with outside clients.
  M: The best part of that course is that it shows you that ethnographic research can also be done on a familiar ground.
  W: Yeah. I got the idea for my project from reading Robert Marshal’s study of office life and I realized I already had some background in that. So far, I’m really enjoying this course.
  Questions 23 to 25 are based on the conversation you have just heard.
  23. What is the conversation mainly about?
  24. What does the woman say about the subject of ethnography?
  25. Who is the first person the woman will interview?
  Section B
  Passage One
  Penury was what people called a mystery man. We had known him for over seven years, ever since he became a member of our modest club, but he had a way of keeping his private life to himself in all but the unessential details. We knew his address, though he never invited us to his home, and his age, too, but only unimportant matters of this kind. It seemed that he did not have to work for a living as we did, in our various ways. He had once hinted about an inheritance on which he managed to live comfortably. He was not, however, a man of luxurious habits: he was not especially well dressed and he did not even have a car. At the age of forty-five he was still a bachelor though. Since marriage was not a subject he ever discussed, we had no means of finding out whether he regretted not having a wife.
  Penury disappeared suddenly from our circle and shortly afterwards we came to learn the first really solid facts about our mystery man. From reports that appeared in the newspapers, together with photographs of the man who was without doubt, our Mr. Penury, it was revealed that he was the most accomplished burglar in the London area; and that he had practiced this profession for many years, until he was arrested and sent to prison.
  Questions 26 to 28 are based on the passage you have just heard.
  26. Why did the author think Penury was a mystery man?
  27. Which of the following descriptions of Penury is TRUE?
  28. What was Penury’s profession?
  Passage Two
  Abraham Lincoln was born in a log cabin in Kentucky on February 12, 1809. When he was a small boy, his family moved to the frontier of Indiana. Here, his mother taught him to read and write.
  When Lincoln was a young man, his family moved to the new state of Illinois. Lincoln had to earn a living at an early age, but in his leisure time he studied law. He soon became one of the best known lawyers in the state capital at Springfield, Illinois. It was here that Lincoln became famous for his debates with Stephen on Douglas on the subject of slavery.
  In 1860 Lincoln was elected President of the United States. He was the candidate of the new Republican Party. This party opposed the creation of new slave states. Soon after his election, some of the Southern states withdrew from the Union and set up the Confederate States of America. This action brought on the terrible Civil War, which lasted from 1861 to 1865.
  On January 1, 1863, during the war, Lincoln issued his famous Emancipation Proclamation. In 1865, after the war ended, the Thirteenth Amendment was added to the Constitution of the United States. This amendment put an end to slavery everywhere in the United States.
  Early in 1865, the Civil War came to an end with the defeat of the South by the North. Only a few days after the end of the war, Lincoln was shot by an actor named John Wilkes Booth. The President died on April 14, 1865. In his death, the world lost one of the greatest men of all time.
  Questions 29 to 32 are based on the passage you have just heard.
  29. When was Lincoln elected President of the United States?
  30. How many years did the Civil War last?
  31. Who shot Lincoln?
  32. Why did some of the Southern states withdraw from the Union?
  Passage Three
  If you’ve been on campus for very long, I’m certain that you’ve already heard about this course. You may know that last semester about 50 percent of the students enrolled in my course failed it. Let me explain how this came about before you jump to any conclusions. In the first place, since this is a composition class, I expect my students to follow certain roles of formality. Unfortunately, many students today dislike having to follow roles of any kind, especially those that they may feel to be unnecessary. For example, I ask that each of your papers be typed and centered on the paper correctly. I count off points for various kinds of mistakes. A misspelled word will cost you 5 points. You’ve lost 25 points if you’ve misspelled five words. If you write in complete sentences, you’ve lost 10 points. If you give me two complete sentences as one without adequate punctuation, you’ve lost 15 points. I do not accept late papers. You will receive a zero for any theme which you fail to submit on time. I expect you to read each assignment. I will give you a short unannounced quiz from time to time. This class meets on Mondays, Wednesdays, and Fridays. If you have any questions at any time, you can see me on Tuesdays. My office is on the second floor of this building. Your assignment for Wednesday is to read Hemingway’s short story on page 55. Friday will be the last class day of this week, so you can expect to write a short in-class theme for me then. That’s all for today, I’ll see you on Wednesday.
  Questions 33 to 35 are based on the passage you have just heard.
  33. How many points will a student lose if he misspells a word on a composition?
  34. What will the students do in class on Friday?
  35. What must the students read for Wednesday?
  Section C
  Scientists have developed a new cancer drug. So far, they have tested it only on (36) laboratory animals. The drag is designed to (37)invade and kill cancer cells but not healthy cells.
  First, the drug enters the cancer and destroys the supply of blood. Then it releases (38)poison to destroy the cancer cells.
  Researchers at the Massachusetts Institute of Technology in Cambridge carried out the study. The (39)results appeared in Nature (40) magazine. A school news release called the drug an "anti-cancer smart bomb".
  Ram Sasisekharan is a professor at M.I.T. He says his team had to(41)solve three problems. They had to find a way to destroy the blood vessels, then to (42)prevent the growth of new ones. But they also needed the blood vessels to supply chemicals to destroy the cancer.
  So the researchers designed a two-pan "nanocell". The cell is (43) measured m nanometers, or one thousand millionth of a meter. (44)The particle used was two hundred nanometers-much, much smaller than a human hair.
  The scientists say it was small enough to pass through the blood vessels of the cancer, but it was too big to enter normal blood vessels. The surface of the nanocells also helped them to avoid natural defenses.
  (45)The scientists designed the cell as a balloon inside a balloon. They loaded the outer part with a drug that caused the blood vessels to fall in on themselves. That cut off the blood supply and trapped the nanocell inside the cancer. Then, the nanocell slowly released chemotherapy drugs to kill the cancer cells.
  (46)The team says the treatment shrank the cancer and avoided healthy cells better than other treatments.
