¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®1. A: The tickets for that rock concert finally go on sale next Saturday at five o’clock.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I heard that anyone who wants one had better get there sooner than that.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®2. A: Your train will be ready for boarding in fifteen minutes, sir. Breakfast will be
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®offered in the dining car.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Good. I’ll have just enough time to send a fax before leaving.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man plan to do next?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®3. A: Shall I cut your hair for you?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: No way. Last time you almost made me bald.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®4. A: I have to call the apartment manager.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Lost your keys again, huh?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®5. A: Would you like to try the new seafood restaurant tonight? I hear it’s very good.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I have to give a presentation tomorrow and I need to do a trial run.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®6. A: Uh huh. Somebody left their wallet here.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: See if there is some kind of identification in it.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man suggest the woman do?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®7. A: Dr. Smith asked us to watch that special on the Civil War on TV this weekend. Do
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®you want to come over Saturday night?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Oh, I’m supposed to help my cousin move then. It’s being rebroadcast on Sunday
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®afternoon though. Is that OK for you?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®8. A: I don’t know how I managed to break that platter. I’ll be more than happy to buy
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®you a new one.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Forget about it. Some things just can’t be helped.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®9. A: I wonder if there is a bus that goes by the museum.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: The history museum on Main Street? Take one that says eight “A” on the front.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®10. A: It’s pouring. We’re never going to make our flight if we don’t leave soon.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Oh, don’t worry so much. I’m sure we’ll get there in plenty of time.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®11. A: Hey, there’s a program on the radio tonight at seven you might like. It’s about
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®owls.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I hadn’t heard about it. But you’re right, I am interested.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What will the woman probably do?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®12. A: How long can you keep the videotapes?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: If they are not returned by the time the media center closes tonight, I’ll have to pay
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®a fine.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®13. A: So you need some one to watch your cats while you’re away.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Would that be a problem for you?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man want to know?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®14. A: Jane told me she’d meet me here at the library reference desk at one o’clock.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®But she hasn’t shown up yet.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Oh, I just saw her upstairs in the third floor study lounge. She said she had been
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®expecting you at 12:30.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man say about Jane?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®15. A: Could you give this note to Mitchell?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Give it to Mitchell? What am I? a messenger?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®16. A: I’m sorry I forgot to return your physics book last night.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I’ll forgive you considering the test isn’t till Friday.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®17. A: I’m having a lot of trouble with calculus and my professor can’t seem to explain it in
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®a way that makes sense to me.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: You know, the student government runs a tutoring service. I was ready to drop
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®trigonometry last semester before they helped me out.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man suggest the woman do?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®18. A: I see that your roommate Donna’s editor of the newspaper this year.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Editor yes, but you’d never know she was my roommate. I’ve hardly seen her
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®since the beginning of the term. She might as well move her bed over to the
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®newspaper office.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What can be inferred about Donna?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®19. A: John, I really can’t afford any more interruptions right now. I’ve got to finish this
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®assignment.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I’m sorry Cathy. Just one more thing, I forgot to ask you if you could give me a
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®ride to school tomorrow.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What can be inferred about the man?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®20. A: I’m really disappointed about not getting that job.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: An evening at the Jazz club ought to make you feel better.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man suggest the woman do?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®21. A: Every single book I need for my report is off the shelves.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Tough luck.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®22. A: I’ve got five pairs of pants and seven shirts packed.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: You’ll be away for a while then.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®23. A: I just admitted my entry for the art club’s photography contest.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I had no idea there was going to be one.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®24. A: Do you ever get tired of all the talk about fat and cholesterol?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Do I? You know sometimes I think it’s just a fad. How can so many different
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®things be bad for you?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®25. A: I thought you were going to call me last night about the train schedule.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Sorry, I would have. But Harry and Jack stopped by and stayed past midnight.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®26. A: I’ll read you the main points of the report over the phone.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Great. That’ll help me stay on top of the project till I’m able to come back to work.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man mean?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®27. A: I’ll be happy to show you more spacious unit on the twelfth floor.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Please do. This place is nice but it seems pretty cramped.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®28. A: I hear you did some serious shopping this past weekend.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Yep. The speakers from my old stereo finally gave out and there was no way to
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®repair them.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What did the woman probably do over the weekend?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®29. A: We are thinking of taking the kids to the new aquarium this weekend. Do you think
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®it’s worth the trip?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: I’ve heard good things about it. I hope I get a chance to go myself soon.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the woman imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®30. A: It’s a tradition. Every New Year’s Day my sister and I go skating on the lake.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®B: Has it been cold enough this winter? Or will you go indoors?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What does the man imply?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Part B
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Questions 31-35 Listen to a conversation between two students who’ve met on campus.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®How do you and your housemates like the new co-op? I’m thinking of joining it
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®myself.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®We like it quit a bit. We get some very fresh produce and both staples and fair prices.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®But it certainly hasn’t saved us time. The co-op doesn’t carry everything. So we still
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®wind up going to the supermarkets too, for cleaning supplies, batteries, that sort of thing.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®I wish the co-op sold those items. I’ve been talking about it with some of the other
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®members.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What do members have to do? Just pay a membership fee?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Yeah. There’s a fee and there’re meetings. But attendance isn’t acquired. But we
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®do have to work there for an hour every week, which isn’t too bad. Once you are there
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®you can get your shopping done.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®I wouldn’t mind working there sometime. You’ll get to know about the products. But
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®is the food free of additives. That will be the main reason I join. I’m a convert from
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®junk food. Until now my diets have been largely chemical additives and pesticides.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Well, a lot of food is pure and pesticide-free. They also have vitamin supplements
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®and soy and tofu and that kind of thing. Lots of health food enthusiasts shop there. So
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®if any source health oriented, the co-op is.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®I’d like to try it just for a month or so. Do they have trial memberships?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®The shortest membership time is one month. Then if you like it, you can join for
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®longer periods. And it becomes cheaper. A six-month membership costs as much as
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®five individual months.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Sounds pretty easy. Maybe the next time I run into you again it’ll be at the checkout
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®line in the co-op.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®31. What are the speakers mainly discussing?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®32. What change does the woman suggest the co-op make?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®33. What is one thing members of the co-op must do?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®34. Why might the man join the co-op?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®35. What is the advantage for the people who join the co-op for a six-month period?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Questions 36-39 Listen to a conversation between two students in the campus cafeteria.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Gosh! Fred. Another cup of coffee? That’s your third since lunch.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Yeah. Well, I stayed up all night cramming for my history exam. I couldn’t keep my
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®eyes open in my last class. I’m having this coffee so I can stay awake this afternoon.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Don’t you know that drinking too much coffee is harmful?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®What do you mean harmful?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Well, for one thing, it may cause heart disease.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Nah. Most of the research about the link between coffee and heart disease is
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®inconclusive.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®But coffee has caffeine which is addictive.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®You can’t become addicted to caffeine like other drugs.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Yes, you can. Don’t you know that people who are deprived of caffeine suffered
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®withdraw symptoms especially headaches.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®One cure for headaches, oddly enough, is caffeine. Haven’t you ever noticed that
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®many over-the-counter headache remedies use caffeine as one of their ingredients?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Besides, coffee helps me work faster.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Studies have shown that coffee makes you work faster, but not necessarily better.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®You may finish your exam in a shorter period of time but you won’t have fewer errors.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®You know, that soda you’re drinking has caffeine in it too.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®But twelve ounces of soda has only half the caffeine of a five ounces cup of coffee.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®And a cup of tea has less than that.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®But I like the taste of coffee.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®You could drink decaf.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Decaffeinated coffee doesn’t have as much flavor or body as regular coffee.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Besides, I want something that will keep me alert in class.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®36. What is the conversation mainly about?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®37. What is the man’s problem?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®38. What does the man say research shows about coffee?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®39. What does the woman probably think about coffee?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Part C
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Questions 40-43 Listen to part of a lecture in a composition class.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®By the end of the term, I hope you will be convinced as I am that formal writing always
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®requires revision. Sometimes it requires a fairly major rewriting of the paper. Some
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®students have the mistaken idea that revision means simply making corrections in spelling
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®and grammar. I call that proofreading. What I expect you to do with your revise is to
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®evaluate and improve the overall effectiveness of your paper. But how can you tell if
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®your paper is effective?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Well, for example, start by asking yourself these questions: Is the topic restricted
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®enough to be fully discussed within the given length? Are the main ideas clear? Are
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®they supported by specific details and examples? Do they move smoothly from one idea
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®to the next?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®You need enough time for a possible major overhaul. That is you may have to make
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®a lot of changes before your paper becomes really clear to the reader. So I’ll expect a
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®preliminary draft of each paper two weeks before the final due date. That way I can
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®criticize it and get it back in time for you to revise it. Then you can submit a final draft for
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®grading.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®This process may seem like a great deal of trouble at first, but I think you’ll find it
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®valuable. In fact, after you finish this course, I doubt that you well ever turn in a term
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®paper without first revising it carefully.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®40. What is the purpose of the talk?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®41. What should be the students’ main goal as they revise their work?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®42. When should the first drafts be turned in?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®43. What effect does the instructor think the class will have on the students?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Questions 44-46 Listen to part of a radio program about environmental issues.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Are electric cars the way of the future? Automobile manufactures are under pressure
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®to develop cars that do not pollute. One powerful motive is a California law requiring that
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®by the year 2000 ten percent of new car sells in the state be so called zero-emission
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®vehicles. These cars must put no pollutants whatsoever into the atmosphere.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®California is a huge market for the automobile companies, so they are working hard to
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®meet these standards. So far the electric car seems to be the best alternative. So the
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®big advantage of electric cars is that they don’t pollute. However they will be in
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®competition with gas-powered cars and that’s where the weaknesses come out.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®The big problem is that the batteries that power electric cars weigh a lot relative to the
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®amount of power they deliver. For instance, in one prototype electric car, the batteries
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®weighed 400 kilograms. And they provide enough energy to go 250 kilometers before
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®recharging, which takes eight hours. Compare that to a moderately fuel-efficient
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®conventional car, it can go 600 to 700 kilometers on a tank of gas and refilling takes just
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®minutes. If there are other drains on an electric car’s batteries besides the motor,
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®headlights, air-conditioning or a heater, its already limited range will be significantly
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®reduced. So automobile engineers are trying to make more powerful batteries that would
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®increase the cars’ range and make them more attractive to buyers.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®44. What is the talk mainly about?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®45. What is the main advantage of electric cars over gas-powered cars?

¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Questions 47-50 Listen to a talk given at a museum of natural history.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®I’d like to welcome you all to the Museum of Natural History. Today’s tour will take us
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®through our newly renovated dinosaur exhibit where we have the largest collection of
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®dinosaur fossils anywhere in the world.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Before we begin the tour, let me mention that there have been some major
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®modifications to some of the exhibits over the past three years. Basically these changes
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®were made because of recent changes in the way scientists interpret dinosaur behavior.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®For example, when we get to the first room, you’ll be able to see that the tyrannosaur’s
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®rex skeleton is no longer standing upright with its tail dragging on the floor. That’s
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®because paleontologists as they examined the area around its footprints more closely,
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®realized they could find no evidence of a heavy dragging tail which would have left behind
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®marks in the earth. In its new position, the backbone is parallel to the floor, its head is
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®pushed forward and its tail is stretched out acting as a counterweight. This new pose
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®stresses the relationship between dinosaurs and modern birds and supports the theory
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®that dinosaurs are actually more closely related to birds than to any other existing
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®creature.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®Let me also point out that we have changed the way we grouped dinosaurs in our
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®displays. There’s a new school of thought called kledistics where scientists determine
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®relationships among the animals according to common physical characteristics. The
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®plesiosaurs and the oviraptour for instance, are separated by 148 million years. But
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®they are grouped together here, because they both have a grass bean forefoot and an
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®s-shape neck, physical evidence that they are indeed related. So now the exhibition
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®halls are arranged more like a family tree rather than the work-through tine that they used
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®to be.
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®47. Why has the museum modified its dinosaur exhibit?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®48. According to the speaker what is the tyrannosaur’s rex new position evidence of?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®49. Why are the plesiosaurs and the oviraptour displayed together?
¥fø-9ÚEiforum.liuxuehome.comN0ÌÙäd¦®50. How were the dinosaurs originally grouped in the exhibit?
