Script 听力理解原文
第一节Section a
1. W: Mark is playing computer games.
M. Should he do that when the final exam is drawing near?
2. W: Jack seems to think that this year’s basketball season will be disappointing.
M: That’s his opinion. Most others think differently.
3. W: Is this the check-in counter for Flight 914 to Los Angeles?
M: Yes. But I’m sorry the flight is delayed because of a minor mechanical problem. Please wait for further notice.
4. W: Excuse me, I’d like to place an advertisement for a used car in the Sunday edition of your paper.
M: OK. But you have to run your advertisement all week. We can’t carry it for just Sunday. 5. W: Hello, Joe, haven’t seen you for a while. Are you fine?
M: Oh, yes, but nothing seems to be going right for me. I had a car accident, only a few minor injuries, though.
第二节Section b
6. M: What does your father grow, Marie?
W: He grows potatoes and cabbages, and other things like that, but he grows more wheat than vegetables.
M: And what is that building? It doesn’t look like a house.
W: You are right. We keep cows in it.
M: Mm, I see. That must be the house you live in.
W: Yes. It was built two hundred years ago. It’s very old. But we don’t want to change it. We have been living here since 1938.
M: That’s right. It’s much more interesting than modem houses.
W: I agree.
M: Well, when are we going horseback riding, Marie?
W: Let’s go right after I give you a tour of the farm.
M: OK, that’s great.
7. M: Hi, young lady. How may I help you?
W: Well... yeah. I’m looking for a Father’s Day’s gift.
M: Okay. How about getting your father a new wallet?
W: Hmm. How much is that wallet?
M: Huh... which one?
W: The black one.
M: Oh. It’s only $ 40.95
W: Huh? That’s too expensive for me. Do you have a cheaper one?
M: Hmm. How about this brown leather one?
W: Hmm... I don’t think my father will like the design on the outside, and it doesn’t have a place to put pictures. How much is it anyway?
M: It’s $ 25.99.
W: Hmm. I don’t have that much money.
M: Okay. How much do you have to spend?
W: I’m not sure. Probably about ten dollars or so. I’ve been helping my mo m around the house for the past week to earn some money. This is all I have.
M: Hmm. How about this tie?
W: That’s real pretty, but the price tag says $13.99, and I know I don’t have that much money.
M: Well, let’s just say the tie just went on sale. How about $5.00? What do you say?
W: Oh, thanks. I’ll take it.
W: Wake up, Erik, time to rise and shine.
M: Ha, oh, hi, Jane, I must have fallen asleep while I was reading.
W. You and everyone else. It looks more like a campground than a library.
M: Well, the c lassroom’s too noisy to study in and I guess this place is too quiet.
W: Have you had any luck finding a topic for your paper?
M: No, Professor Grant told us to write about anything on Eastern culture. For once I wish she had not given us so much of a choice.
W: Well, why not write about Chinese culture? You seem to be interested in that part of the world.
M: I am, but there is too much material to cover. I’ll be writing forever, and Professor Grant only wants five to seven pages.
W: So then limit it to one place in China, say Beijing. You’ve been there and you said it’s got lots of places of interest and you enjoyed your trip very much.
M: That’s not a bad idea. I brought many books and things back with me last summer. That would be great resource materials, now if I can only remember where I put them.
9. W: So Peter, you’re going to tell us how to make a million.
M: Well, to go back to the beginning, um, I went to study design after leaving school. And
I was there for two years, um when I left college, I decided to go off and see a bit of the world.
W: Where did you go?
M: Well, a friend of mine got a job in Brazil, so I decided to go and have a look at Brazil. And I had a wonderful time. The social life was very good, and I made a lot of wonderful friends. Some of these friends then decided to drive up to the USA. It seemed like a very good opportunity to see some more of the world, so I joined them. But we had a terrible experience in Central America. We were stolen away by force by bad men, believe it or not, and it was two year before I got away from them.
W: What an extraordinary experience!
10. Well, I think generally speaking, we could say that there are four stages to culture shock. First of all, the “honeymoon” st age. Uh, to the visitor, everything seems new, unusual, and strange. The food, the surroundings, the buildings. And it produces a feeling of excitement—a desire to look around, to experiment, and to explore.
The next stage is the “horror” stage, where the newness wears off, and the visitor sees the country from a different perspective, and often begins to criticize the country, the life, and the values of the people.
The next stage, we could say, is the “humor” stage, where people begin to reflect back and laugh at their mistakes in the earlier stages.
And the final stage, we could say, is the “home” stage where people begin to feel at home, and enjoy living in that foreign country.
