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.
