【答案解析】[解析] 19-22
W: When are you going to finish that book on American History?
M: Oh, I should get through it sometime this weekend I guess. Anyway, it was only a week since I borrowed that book from you.
W: Well, if you finish it tonight, I can take it back to the library tomorrow on my way home from work.
M: What's the hurry? Don't you have anything else to read?
W: I won't have anything if I don't get to the library tomorrow.
M: You read too much.
W: I'd rather read than watch television. The TV programs seem to be getting worse all the time.
M: Well. I don't think I can read that fast, but I do enjoy reading, especially novels and biographies or the like.
W: What do you think about joining a book club? If we join one, we can keep up with all the latest bestsellers.
M: That's sort of expensive, isn't it?
W: It isn't any more expensive than going to a movie, the way admission prices have gone up. And the new movies don't seem to be much better than TV.
M: How does the book club work?
W: With the Internet, it's much easier and faster than it used to be. Once you have gone through the registration online, a catalogue of books will be sent to you every month, and you can choose as many books from it as you want.
M: What do you do if you don't like any of the books?
W: You have to take four each year, that's all.
M: What happens if you decide you don't want a book that they do send you?
W: You can return it.
M: And what about the prices?
W: The books are cheaper than they are in bookstores even with the mailing costs added in.
M: Well, go ahead; join a book club if you want to.
