【答案解析】[听力原文]
   W: Hi, John. Your roommate told me that I could find you in the TV lounge. What are you doing here?
   M: What does it look like I am doing?
   W: Well, it looks like you are watching television. But we have a math midterm tomorrow, so I thought you'd be studying for it and maybe I can study with you.
   M: Oh, well, I was just taking a break. This math stuff gives me a headache if I work on it too long.
   W: I know what you mean. I've been working on it for three hours already. I'm beginning to go cross-eyed. I'm having trouble with the sample problems. I just don't get some of them.
   M: But I can't believe you are coming to me. I mean, you do know what I got on the last test, don't you?
   W: Yeah, I know. You told me. I just thought two heads might be better than one.
   M: Yeah, that is a good idea. But you know, I wish I knew that person in our class who got a hundred on the last test. She didn't miss a question. Umm...was it Elizabeth?
   W: Oh, yeah, Elizabeth! She is a friend of mine. She'd be a big help right now. Why don't I give her a call?
   M: What! At this hour? It's already ten thirty. I don't want to impose her.
   W: Yeah, I guess you are right. But you know what? She owes me a big favor. Let's at least give her a call and see what she says. Maybe going over some of the problems with us would help her review the material too.
   M: It's worth a try.
