听力原文:M: Is this table in the comer okay?
W: Sure. We can sit here.
M: Gee, you've hardly got anything on your tray.
W: Yeah, I guess I'm just not that hungry.
M: What's the matter? Aren't you feeling well?
W: Well, I've been really worried. It's my car. It's in the shop again.
M: Really? What's wrong this time?
W: I don't know exactly. Something's wrong with the brakes, I think.
M: well, at least that shouldn't cost you much to fix. Parts are cheaper for all the American cars like yours. Did the mechanic say how much it would cost?
W: He said he would call me with an estimate later on today.
M: Watch out he doesn't try to take advantage of you.
W: What do you mean?
M: Well, some car mechanics, if they think that someone doesn't know much about cars, they might try to overcharge that person.
W: Maybe so. But I trust this guy. He was recommended by one of my neigh hors. He has done some work for me in the past and his prices seemed to be reasonable.
M: Oh, that's good to know. Maybe I'll try using him in the future. By the way, do you need a ride home after class today?
W: Oh, I'd sure appreciate it. It's really tough getting around without a car when you live off campus.
