听力原文：W: Look, so many people are crowding through the gates into the exhibition halls. M: But last year they had fewer visitors to the Fair. This year they have more visitors since the economy is booming. W: You can't call them visitors. They are businessmen from all over the world. M: I know. The World Fair plays a very important role in the international trade. Look, what an array of products! W: Here's a pamphlet. It says there are 80 kinds of products, 100 if the trial products included. M: That's impressive. W: What are you interested in? M: The handicrafts and office equipment. What about you? W: I have no interest in that. I'd like to see the fashion. I'm in the textile business. M: Well, here's something special. The tag on the material says it is still experimental. W: Mm ... It's very attractive. M: It looks like leather. Is it made of leather or paper? W: It is made of paper. It's treated with a special coating. M: It's very realistic. I think there would be a lot of application. W: I'd like to talk to the company that makes them. I want to place an order with it if the price is right. M: Let's go to the conference room. It's on the third floor. We can take the lift. W: But the sign says the lift is broken. We have to walk upstairs. (23)
