听力原文：W: Welcome, Mr. Johnson. Take a seat, please. Our manager will be back soon.

M: Thank you. Urn, it's rather warm these days, isn't it？

W: Yes. The weather is quite unusual at this time of year.

M: You're right. Er...do you mind if I take off my jacket then？

W: Sure. Make yourself at home.

M: Thank you, that's better. Urn...do you mind if I smoke？ I notice nobody's smoking around here.

W: Well, I'm sorry, but this is a non-smoking office building.

M: Oh, that's OK. I'm trying to quit it anyway. By the way, may I use your phone to book a table...for lunch？

W: Yeah. Sure. Do you know which restaurant is good？

M: Oh, yeah, absolutely.

W: Fine. The phone is over there.

M: Thank you.
