听力原文：W: Wake up, Erik, 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 with she had not given us so much of a choice.

W: Well, why not 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.

M: 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.

SECTION A CONVERSATIONS

Directions: In this section you will hear several conversations. Listen to the conversations carefully and then answer the questions that follow.

听力原文：W: How can I help you？

M: I'd like to return this sweater for a refund. I bought it a week ago.

W: Well, what seems to be the problem？

M: Isn't it obvious by just looking at it？ The first time I washed and dried it, the thing shrank at least five sizes.

W: I see what you mean, but did you follow the washing instructions？ I think it says here ... right here on the label to hand wash it and then to dry it on low heat.

M: How was I supposed to know that？ The label is written in Chinese! And something else i The stitching is coming undone and the color faded from a nice dark blue to a seaweed green.

W: Listen, sir. What I can do is allow you to exchange the sweater for another one.

M: I don't want to exchange it for anything! I just want my money back!

W: Well, I can give you credit on your next purchase, and since the item you purchased was on clearance, we can't give you a refund. Anyway, you can only return items with a receipt within six days, and unfortunately, that was yesterday in your case.

M: But, your store was closed yesterday because of the national holiday. Listen, I give up. Your store policies are completely unreasonable, and how do you expect people to shop here？

W: You did... Ha, ha...

M: Take your sweater. You should open up a pet store and sell it as a dog sweater.
