听力题M: The Energy Minister announced at a press conference yesterday, the construction of three more nuclear power stations. These will form a vital part of the government''s energy plans for the next two decades and are needed to satisfy the country''s growing demands for electricity. The plans were strongly criticized by opposition MP''s as well as anti-nuclear and environmentalist groups. W: They must be absolutely mad. More nuclear power stations! M: OK. Jane. But we''ve got to get the energy from somewhere, haven''t we? We can''t just go on using oil and coal. W: Look. The main point is they''re just not safe. They''re a real menace. Every one of these things is an accident waiting to happen. Look at Chernobyl, for goodness'' sake! M: Yes, OK. I agree there''s a risk. Of course there is. But it''s minimal. With modem technology, nuclear reactors are much safer. W: Much safer! You must be joking. No. Look at all that radioactive waste they''re dumping into the sea and underground. Nobody really knows what''ll happen long-term. M: That is a problem. Sure. But it''s also true that nuclear energy is cheap and can produce electricity very quickly. Lots of countries have no alternatives. They don''t have any oil, coal or anything. What are they supposed to do? W: Oh, come on! There''re lots of possibilities. Well, quite a few. We just haven''t really looked at them seriously enough. There''s solar energy, and wind power and, what''s called, wave power. We''ve still got a lot of coal. W: Alright. But they''ll all take time and money to develop. We need energy now and nuclear power is the best alternative. M: Oh, I don''t believe this. I reckon it''s just crazy.

听力题 One way that scientists learn about man is by animals, such as mice, rats and monkeys. The scientists in this laboratory are experimenting on mice. They are studying the relationship between diet and health. At this time over one hundred experiments are going on in this laboratory. In this experiment, the scientists are studying the relationship between the amount of food the mice eat and their health. The mice are in three groups. All three groups are receiving the same healthy diet. But the amount of food that each group is receiving is different. The first group is eating one cup of food each day, the second is eating two cups, and the third group of mice is eating three cups. After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group are thinner than normal mice. But they are more active. Also they are living longer. Mice usually live for two years. Most of the mice in this group are still alive after three years. The second group of mice is normal weight. They are healthy, too. They are active, but not as active as the thinner mice. But they are only living about two years. The last group of mice spends most of the day eating or sleeping. They are not very active. These mice are living longer than the scientists thought; about a year and a half. But they are not healthy. The experiment is still going on. The scientists hope to finish their studies in two years. One way that scientists learn about man is by animals, such as mice, rats and monkeys.

听力题 To what degree can a computer achieve intelligence? The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet. If you ran into Smarter Child online, you would be surprised at this kid''s huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season. He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child''s age returns. "One year, 11 days, 16 hours, 7 minutes, and 47 seconds!" Asking where he lives gets, "In a clean room in a high-tech building in California." Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com. Some scientists believe that by joining the many systems of the Internet. However, if Smarter Child wants to think and learn on his own like the boy— computer David in the movie A. I. Artificial Intelligence, he must overcome two problems. The first is that computers find it difficult to read web pages because the files are labeled in different ways. That''s why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself. Another problem is that while Smarter Child can process information more exactly and faster than any human, he lacks common sense-a basic grounding of knowledge that is obvious to any young child.

听力题W: We''re having a debate on advertising tomorrow and I have to take part. M: That''s interesting. I should like to hear what young people think about advertising. W: Well, we wouldn''t know what there was to buy if we didn''t have advertisements. M: Yes, that''s true—up to a point. Advertisements provide information that we need. If someone has produced a new article, naturally the seller wants to tell us about it. W: Yes, and advertisements tell us which product is the best. M: Do they? I don''t think so. Every manufacturer says that his product is the best, or at least tries to give that impression. Only one can be the best, so the others are misleading us, aren''t they? W: Well, I suppose, but we don''t have to believe them, do we? M: Are you saying that advertisements aren''t effective? I don''t think that intelligent businessmen would spend millions of dollars on advertising if nobody believed the advertisements, do you? W: Perhaps not, but after all, it''s their money that they''re spending. M: Is it? I think not. The cost of advertising is added to the price of the article. You and me and all the other people who buy the article pay for the advertising! W: Well, I suppose we get something for our money—some information. M: Yes, but don''t forget it''s often misleading information, and sometimes harmful. W: We''re having a debate on advertising tomorrow and I have to take part. M: That''s interesting.

听力题W: I usually advise first-year engineering students to take mathematics, chemistry, and an introductory engineering course the first quarter. M: Oh. That''s only three classes. W: Yes. But I''m sure that you''ll be busy. They''re all five-hour courses, and you''ll have to meet each class every day. The chemistry course has an additional two-hour laboratory. So that would be seventeen hours of class a week. W: That''s right. M: Okay. Which mathematics course do you think that I should take? W: Have you taken very much math in high school? M: Four years. I had algebra, geometry, trigonometry. W: Good. Then I suggest that you take the math placement test. It''s offered this Friday at nine o''clock in the morning in Tower Auditorium. M: Do I need anything to be admitted? I mean a permission slip? W: No. Just identification. A driver''s license will be fine. M: Do I take a chemistry test too? W: No. Chemistry 100 is designed for students who have never taken a chemistry course, and Chemistry 200 is for students who have had chemistry in high school. M: I''ve had two courses. W: Then you should take Chemistry 200, Orientation to Engineering and either Mathematics 130 or 135, depending on the results of your placement test. Come back Friday afternoon. I should have your score on the test by then and we can get you registered.
