听力原文：W: I haven't seen you here for a couple weeks. Have you stopped eating or something？
M: No. Does it look like l've stopped eating？ I've been spending a lot of time in the library.
W: Working on a paper？
M: I wish it was one paper! I'm Working on three different papers anthropology, English literature, and history.
W: Wow! That is a lot of work.
M: Yeah, and what's frustrating is that I'm studying the nineteenth century British Empire in all three classes, but I can't just write a single paper for all three.
W: Why not？
M: The professors won't let me, even if I make it three times as long as the suggested length.
W: That's too bad. Could you write your papers oh three aspects of one topic？
M: Hmmm. What do you mean？ Do you have something in mind？
W: Well, let's see. Hmm Maybe you could do something with Romanticism, like. oh... write your anthropology paper on the cultural basis of Romanticism, and, uh, your history paper on the influence of the Romantic poems on British foreign policy, and, OK, and your English lit paper on an analysis of some Romantic poems.
M: That's not a bad idea! I've already stared the research for one of the paper, so 1 can use that. What can 1 do to repay you？
W: You want to write up my chemistry lab for me？
M: I'd love to, but I,ve never taken chemistry, so I'm afraid you won't like the results.
W: Oh well, no thanks necessary then. Have a good weekend. See you later.
M: See you.
