听力原文：W: David! Can I give you a hand with one of those grocery bags？
M: Sure, Nancy! Could you take this one, please？ I didn't realize how heavy these bags would be.
W: Why did you buy so much stuff when you have to walk home from the store？
M: Well, I didn't intend to buy a lot—but I'm having some people over and I guess I needed more than I expected.
W: What' s the occasion？
M: The people I live with, the Kramers, have been on vacation for a month, and I thought I' d surprise them. I' m inviting some of their friends and family for a welcome-home dinner.
W: That' s really thoughtful of you.
M: I figure it' s the least I can do for them. They' ve been letting me stay with them rent-free while I' m in school.
W: Really？ That' s pretty generous of them.
M: Well, they understand how difficult it is to make ends meet when you' re a student. They' ve been such a big help to me. I thought that this might be a small way to thank them for their generosity.
