【正确答案】
C
【答案解析】[听力原文] A: Hi, Professor. I am here for my 9:00 appointment. B: Good morning. So you're here to register for next semester's classes? A: Yes, that's right. I want to make sure that I am signing up for the courses that I need for my journalism major. B: Let me get out the journalism requirements checklists so we can make sure that you're taking the classes you need. Here we go. Okay, now, how many course hours do you want to have next semester? A: As few as possible. I really don't want to get burned out! B: Well, I can understand that. I was a student once, too, but remember that you need 126 credit hours to graduate, and I suspect you want to graduate in the usual four years? A: Oh, yes, I really can't afford to stay longer than four years! B: Okay, so keeping that in consideration, I would recommend that you take at least 15 to 18 hours each semester. A: Well, okay. I took 15 credit hours each for the last two semesters. And I'm signed up for six credit hours of summer school. Fifteen hours hasn't been so bad, so maybe I'll continue with that. But can we try to schedule my classes so that I get to sleep in a little bit in the mornings? B: Sure, absolutely. And the fact that you took so many credits last semester means you've gotten off to a good start! Have you taken all the required courses for first-year journalism students? A: Yes, I have. Oh, wait a minute! I actually took a biology class instead of a mass communication class. Is that a problem? B: No, it's not a problem. Actually, you need to take two science classes before you graduate, so now you have filled one of those two requirements. But you definitely need to take the mass communication class this next semester because it is a prerequisite for other classes that you need. A: Oh, that's good to know. Well, I'll write down that course to take next semester. Should I take my other science class in the fall semester also? B: It would be a good idea to take that class in one of the next two semesters so you can focus on the classes in your major. Is there a science class offered next semester that interests you? A: There is a geology class that looks interesting, and I've heard good things about the professor. It's offered at three different times, so I should be able to work that in around my other classes. B: Great. So I will sign this for you now. Do you have any other questions while you're here? A: Not that I can think of at the moment. Thank you very much for helping me, Professor. B: No problem. That's what I'm here for. Good luck next semester. What is the relationship between the two speakers?
