听力原文:W: Wake up, Eric, time to rise and shine.
M: Ha, oh, hi, Jane, I must have fallen asleep while I was reading.
W: You and everyone else. It looks more like a campground, 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 Grant told us to write about anything in cultural anthropology. For once I wish she had not given us so much of a choice.
W: Well, why net write about the ancient civilizations 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 Grant only wants five to seven pages.
W: So then limit it to one region of Mexico, Say the Uka town. You've been there and you said it's got lots of interesting relics.
M: That's not a bad idea. I brought many books and things back with me last summer, that would be great resource material, now if I can only remember where I put them.
