W: Hi, Kevin.(1)________________________________.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 an advanced Mathematics mid-term 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 advanced Mathematics 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 across.(2)________________________________________.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's a nice 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 on 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.(3)_____________________________________.
M: Well, it's worth a try.
