听力原文：W: Hi, Mark! How's it going? M: Well, not so great. W: What's wrong? M: I've got a big problem with file poetry course that's required for my major. W: Is it all filled up? M: No, no. There's plenty of room, but there's prerequisite (前提条件). I've got to take Introduction to Poetry before I can take the special course in poets of the 1960's. And the introduction course is only offered in the evenings. W: You don't like evening classing? M: No, that's not the point. I work in the cafeteria every evening. I need the money to pay my tuition. W: Can't you ask someone at work to switch hours with you? Maybe you could just switch a couple of evenings, since the course probably only meets two times a week. M: I wish I could. My boss just did me a favor by putting me on evenings. And he'll hit the ceiling if I ask to change again. W: Wait a minute. I have an idea. Have you checked the courses over at the community college? They might offer an Introduction to Poetry during the day. M: That's a great idea. I'm free this afternoon. I think I'll go over and check it out. W: Yeah, their courses are actually a lot cheaper, and you can transfer the credits over here. M: Thanks for the advice, Linda. I'll let you know what happens. W: Sure, Mark. Good luck, (20)
