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:(12)I wish I was working on a paper. I’m working on three different papers: sociology, English literature, and history.
W: Wow. That is a lot of work.
M: Yeah. And what’s annoying is that I’m studying 19th 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: Oh. That’s too bad.(13)Could you write your papers on three aspects of one topic?
M: Hum. What do you mean? Do you have something in mind?
W: Well, let’s see. Maybe you could do something with idealism, like—Oh, write you sociology paper on a cultural basis of idealism, 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 the papers. So I can use that. What can I do to repay you?
W:(14)You want to write up my chemistry lab for me?
M: I’d love to. But I’ve never taken chemistry. So I’m not sure you’d like the result.
W: Oh, well. No thanks necessary then.(15)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.
