听力原文：W: Richard, what's that under your paper? M: What's what? W: Lift up your arm. What's this? M: Oh, that. Uh, that's a grocery list. I've got to pick up some things on my way home. W: Do you really expect me to believe that? M: Well, that's what it is. W: (reading) Soren Kierkegaard, Denmark, 1800s, Hegel, Germany, Sartre, Paris, 1900s... An interesting 'grocery' list, Mr. Jackson. M: Oh, gee, let me see that. Oh, my gosh, they must be my notes. How did they get here? W: I'd like to see you in my office, please. (They leave the classroom and go to the office down the hall.) Now, Richard, would you care to explain how the answers to the test questions appeared on your desk? M: I can't. Someone must have left them on my desk. W: Someone left them on your desk? Someone with handwriting identical to yours left them on your desk? I'm afraid I can't accept that answer. M: Are you accusing me of cheating? W: Yes, I am. M: You can't do that without proof! I'm going to call my counselor! W: By all means, do that. In the meantime, however, don't come to class again. I am extremely disappointed in your behavior. (20)
