【答案解析】[听力原文] 14-17
W: Professor Weston, could I talk to you?
M: Yes, but only for a few minutes. I have a meeting at three o'clock.
W: I think this will be quick; I need permission to register for your advanced sketching course.
M: Have you taken the prerequisite, the beginning-sketching course?
W: No, and that's just why I'm here. The catalog says that the instructor can give permission to register without the prerequisite.
M: That's correct. Have you had any previous experience?
W: I've brought lots of sketchbooks full of my work, but I had no formal training.
M: Can I have a look at some of your sketches?
W: Certainly, here are some examples, mostly flowers and landscapes.
M: They look pretty good, but I really don't have time to make a decision now, why don't you give them to me and I'll review them this evening. I'll let you know tomorrow.
W: Thanks a lot. I really appreciate it.
