【答案解析】[听力原文]16-20
W: Can I help you?
M: Yes, I'd like to read some articles that are on reserve in the library for anthropology 311.
W: Professor Gilers's class?
M: That's right. How could you know?
W: Let's just say you are not the first person.
M: Oh, well, seeing as how I haven't read any of them yet, it doesn't really matter which one of them you give me first.
W: I'm afraid I can't give you any of them at the moment. They've all been checked out.
M: You're kidding all of them?
W: I've asked professor Gilers twice already to bring in additional copies of the articles, hut no sooner do I place them on the shelves than they are gone. See that girl in the black sweater? She's been waiting for half an hour for these same articles to be returned.
M: And here I went out of my way to free the whole afternoon to read.
W: I'm sorry, but there is not a whole lot I can do about it. All I can suggest is that you come in first thing tomorrow morning and try again; we open at eight.
