【正确答案】 C

【答案解析】[听力原文]1-5 Susan: Hi, Susan. Where were you at lunchtime? I was saving a seat for you in the cafeteria. Prof: Hall: Oh, sorry to miss you. But my thirst for knowledge was greater than my pangs of hunger. Susan: I never had that problem. So where were you? Prof: Hall: My political science class ran overtime. Susan: That's been happening quite a bit lately, hasn't it? Prof: Hall: I guess so. Actually, what happens is that a bunch of us hang around for a while after class to talk with our professor and ask him questions. Susan: Who is this twentieth century Socrates? Prof: Hall: Professor Hall. Have you heard of him? Susan: Yes. He does have a good reputation in the political science department. Prof: Hall: And a well deserved one. The same students who fall asleep in discussion groups and seminars fight for front row seats in his lectures. Susan: Oh no! I hope this isn't catching. Prof: Hall: You can joke, but it's great to have a professor who's not only interesting but prepared to give up time for students. Susan: I know. They're of a rare breed. Maybe I should sit in on his class sometime. Do you think he'd care? Prof: Hall: Not at all. Lots of students bring their friends and he says he feels flattered. Susan: Well, just to be safe, I think I'll bring my lunch along as well. Prof: Hall: I'll make a good student of you yet.
