听力原文：W: Hi, Mark! How is it going? M: Well, not so great. W: What's wrong? M: I've got a big problem with the poetry course that's required for my major. W: Is that all filled up? M: No, no, there is plenty of room, but there is a prerequisite. I've got to take an introduction to poetry before I can take the special course in poets of the 1960s and the introductory courses only offered in the evenings. W: You don't like evening classes? M: No, that's not the point. I work in the cafeteria every evening. I need the money to pay my tuition. W: Can you ask someone that 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 introductory poetry course during the day. M: Hey! 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 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! Oh, while you are there, can you find out when their pool is open? M: No problem! What prevents the man from taking the poets of the 1960s class?
