听力原文:M: Are you the head resident?
W: Yes.
M: I'm Bill Miller. I'm here because I want to change roommates.
W: Really? That surprises me. I thought that you and David were good friends.
M: We were. You see, we knew each other before. We are from the same home town, but it looks like we had different reasons for coming to college.
W: How so?
M: Well, David is really into having fun, which is great. But he has so many people in our room all the time that I can't study. And the stereo is on constantly.
W: Have you talked to him about it?
M: Yes, but he just doesn't take me seriously.
W: I see.
M: Miss Todd, I have to study. I'm on scholarship. David isn't.
W: Okay. Here's what we can do. Let me talk to David, and then you see how it goes. Just one week.
