听力原文：W: I haven't seen you here for a couple of weeks. Have you stop eating or something? M: No. Does it look as I've stopped eating? I've been spending a lot of time in the library. W: Working on a paper? M: I wish I were working on a paper. I was working on-three different papers: anthropology, English lit, and history. W: Wow, that is a lot of work. M: Yeah! And what's frustrating is that I'm studying 19 century British Empire in all three classes. But I can't write a single paper for all the 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: Oh. That's too bad. Could you write your paper on three aspects of one topic? M: Mm. What do you mean? Do you have something in mind? W: Well, let' s see. Maybe you could do something with Romanticism, such as write your anthropology paper on a cultural basis of Romanticism and your history paper on the influence of the Romantic poets on the British foreign policy and OK and your English paper on analysis of some Romantic poems. M: Hey. That's not a bad idea. I've already started the research for one of my papers. So I can use that. What can I do to repay you? W: You want wrap up my chemist lab for me? M: I'd love to. But I've never taken chemistry. So I'm net sure you like the results. W: Oh, well. No thanks necessary then. Have a good weekend, And try to get out of the library and get some sleep. You have big circles .under your eyes. M: OK. I'll try. See you later. What has the man been busy doing all Week?
