听力原文：M: You should have seen the line at the housing office. It took me an hour to mak

e my dormitory deposit for next year. Have you made yours yet？

W: No, I'm not sure I'm going to.

M: There's not much time left. The deadline's May 1. That is just two weeks from now. Are you short of cash.

W: No, I'm Okay.

M: You'd better hurry up if you want a dorm room next September. There aren't enough rooms for every one, and first-year students have priority.

W: Well, I've been thinking about living off campus.

M: Have you any idea how much that would cost？ There is the rent, utilities, and you'd probably need a car.

M: You should study in the library the way I do. Think of the money you'd save.

W: I've got to think it over some more. There's still two weeks left in April.
