听力原文:W: How many examinations do you have, Tom? M: There, two this week, and one next Monday. How about you? W: Two, both are in this week. Then I have to write two papers. I'd rather have examinations. M: What de you mean? W: Well, you only recite a lot for examinations. You can work really hard for a couple of days, then that's all. M: Yeah, I know. But I like papers better than examinations. Um, where did I put my I.C. card? W: Is it in your desk? M: No, where is it? W: Did you take it back? M: I don't know. Oh, God! I don't know what's wrong with me. (18)
