听力原文:M: Cindy! Have you heard the news? W: No, Steve. What do you mean? M: You know all the classes we've missed because of the snow? W: Uh oh... M: Yup—we're going to have to make them up and the dean says it will have to be during spring break. W: Steve! We have our vacation all set! What are we going to do? Do the others know? M: I don't know but I certainly can't afford to miss five days of classes this semester, with that week I was sick... W: But I really don't want to cancel our trip. All of us have already made our plane reservations! M: I can try to call the travel agency; maybe they can refund our money. But before we do anything we need to speak with our professors. W: You think they'll excuse us from class? M: Probably not. But I was talking to Kevin this morning and he said that one of his professors told him that they could make up the class at a different time. W: Wow—that's great! Which professor was it? M: I don't know. But we're going to have to speak to all of them any way. W: Why didn't they add extra days at the end of the semester before summer classes? M: Because of the graduation date, which can't be changed. W: Are other colleges around here doing the same thing? M: I would imagine so—it's been such a bad winter and we've missed too many classes. We do really need to make them up. W: I know, I know. I was just really looking forward to this vacation. The idea of the sun and the beach! M: Oh look, there's Professor Hampton right now! W: Come on, let's go talk to her! (23)
