W: Hey! (13) Are you going to play some tennis this afternoon?
M: Well, to tell you the truth, (13) I’m not feeling so hot today.
W: Come on. How long has it been since we played?
M: A couple of days.
W: A couple of days? Come on. It’s been more than a couple of days.
M: Yeah. I guess you’re right. It’s been almost a week.
W: (14) It’s been exactly a week.（女士说他们有一个星期没打网球了。也就是说他们上次打网球是一周以前。）And we used to play at least three times a week.
M: I know. Playing right after class was something to look forward to.
W: Yeah. And it was right before dinner. So we build up our appetite.
M: (13) I’ve just been very busy, I guess. And my stomach is bothering me today.（女士邀请男士去打网球，但是男士说他今天没有那个热情，随后解释了原因： 他很忙而且还胃疼。后面详细解释了原因。可见对话是围绕男士为什么不想去打网球而展开的。）
W: But you look OK to me.
M: Well, I was up late with Steve in the library working on a project. We have to turn it in by tomorrow for that anthropology class. We’ve been working on it all weekend. And I was drinking a lot of coffee. I guess I just drank too much.
W: Listen. I took that class last semester. (15) And I could meet you in the library later tonight and help you if you want.（ 男士说他要完成人类学课的方案，女士说她可以帮助男士。）And then you have time to play tennis this afternoon.
M: Yeah. I guess my stomach doesn’t hurt that bad. And I could certainly use your help. But it’s also...
W: Is there something else bothering you?
M: Well, to be honest, I’m getting tired of losing.
