听力题F: Bob, Have you seen any movies recently? M: Yes

听力题M: I really appreciate your filling me in on yesterday''s lecture. W: No problem. I thought you might want to go over it together. Anyway, it helps me review. Hope you''re feeling better now. M: I am. Thanks. So, you said she talked about squid? Sounds a little strange. W: Well, actually, it was about the evolution of sea life — a continuation from last week. The octopus and the squid descended from earlier creatures with shells. They survived by shedding the shells — somewhere between 200 and 500 million years ago. M: That''s a pretty long span of time. W: I know. That''s what she said, though. To be precise: "Exactly when they emerged is uncertain ... and why is still unexplained." M: Some squid are really huge. Can you imagine something that big if it still had a shell? W: Actually, it''s because they lost their shells that they could evolve a bigger size. M: Makes sense. But some are really huge. I''ve read about fishermen that caught squid that weighed over a ton. Did she talk about how that happens? W: Not really. But she did mention some unusual cases In 1933 in New Zealand they caught a squid... let''s see here... it was twenty-two yards long. Its eyes were eighteen inches across. Can you imagine? M: Reminds me of all those stories of sea monsters. W: Dr. Simpson thinks there are probably even larger ones that have been found because squid are intelligent and fast —so they can easily get away from humans. Maybe some of those monster stories are true. M: I really appreciate your filling me in on yesterday''s lecture. W: No problem. I thought you might want to go over it together.

听力题When I was at school

听力题M: Susan! Could I have a word with you while you are having your coffee? W: Of course, David! Let''s find a quiet comer over there. M: The manager asked me to tell you that he appreciated your efforts last year very much. W: Thanks, David. That makes me feel a lot better. I try my best, you know. You can tell him that I am grateful for his confidence in me. M: Yes, I''ll certainly pass that on to him. Your sales figures for the last two years have been remarkably good. W: Manchester is a good area to work in. There are a lot of businesses opening all the time. I try to make contact with the managers as soon as I know a new company is starting up. "The early bird catches the worm!" as they say. M: I''m sure that''s true, but there is more to it than that, isn''t there, Susan? You seem to be very confident and this helps your sales. W: Yes, I''ve been working on that for some time. I think that if I appear confident and successful, people are more likely to buy our goods. M: Well, you certainly seem successful at that. Your sales figures prove that. I was wondering if you could give a short talk tomorrow afternoon on the idea of being confident as a sales representative. Do you think you could put together something on that topic? W: I think I could manage. I''ll work on it this evening. M: I would be grateful if you could do that for me. I''m sure the others would benefit from that kind of talk. W: About how long do you want me to speak for? M: Something like 20 minutes, if that''s all right? W: And what sort of thing do you want me to talk about? M: Oh. How to build up your confidence, present yourself to customers, that sort of thing. W: I''ll work on it later then, David. M: Thanks, Susan... let me take your coffee cup back for you. I think it is about time we got back to the conference. M: Susan! Could I have a word with you while you are having your coffee?

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.
