M: Last time we talked about the history of paper. But do you know what paper is used for?
W: Oh, that’s easy question. Paper is used for newspapers, books, writing paper, envelopes, wrapping paper, paper bags...
M: Yes, actually only half of the paper is made is used for such purposes. Have you got an idea about other uses of paper?
W: No, I’m afraid not.
M: There are many other uses. Paper is very good for keeping you warm. Houses are often insulated with paper. You have perhaps seen homeless people asleep on a large number of papers,(be insulated with... 用......隔热)
W: Yes, I have. So they are insulating themselves against cold.
M: You are right. In Finland, it is very cold in winter. It is sometimes 40 degrees Centigrade below zero. The farmers wear paper boots in the snow. Nothing could be warmer.(Nothing+比较级表示最高级)
W: Oh, that’s unbelievable.
M: Now more and more things are made of paper. We have had paper plates, cups and dishes for a long time. But now we hear that chairs, tables, and even beds can be made of paper.(be made of由......制成)
W: Fascinating!
M:(11)People have made paper boats, but they have not yet made paper planes or cars. Just wait, they probably will.
W: Well, you have become an expert on paper. How do you know all that?
M: You know, I’m preparing for a presentation,(presentation报告;陈述)so I’ve looked up a lot of materials.
W: Well, I’m sure your presentation will go really well.
M: Thank you!
