【答案解析】[听力原文] 14-17
W: Wake up, time to rise and shine.
M: Huh, oh, hi, Lucia. I must have fallen asleep while I was reading.
W: You and everyone else. It looks more like a camp-ground than a library.
M: Well, the dorm's too noisy to study in, and I guess this place is too quiet.
W: Have you had any luck finding a topic for your paper?
M: No, Prof. Gemma told us to write about anything in culture. For once I wish she hadn't given us so much of a choice.
W: Well, why not write about the culture of Mexico. You seem to be interested in that part of the world.
M: I am, but there is too much material to cover. I'll be writing forever, and Gemma only wants five to seven pages.
W: So then limit to one aspect.
M: That's not a bad idea. I brought plenty of books and things back with me last summer from Mexico. That would be great resource material. Now if I can only remember where I put them.
