A、Yesterday before dinner. B、Two days ago. C、Last weekend. D、One week ago. D细节题。女士说两个人已经有一周没有玩网球了。可知他们上次打球是在一用前。所以选D。

W: Hey!(9)Are you going to play some tennis this afternoon?
M: Well, to tell you the truth,(9)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.(10)It’s been almost a week.
W:(10)It’s been exactly a week. 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: I’ve just been very busy, I guess. And my stomach is bothering me today.
W: But you look OK to me.
M: Well, I was up late with Steve in the library working on a project.(11)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.(11)And I could meet you in the library later tonight and help you if you want. 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.
