听力原文：M: I suppose you must have heard about that great piece of concrete falling onto a car in that terrible accident in South Street yesterday, didn't you, Jane？
W: Yes, I saw it in the paper. From a 200-foot high building, wasn't it？ I gather the driver had just got out or he'd have been killed, wouldn't he？
M: Oh, yes. I saw the car; it was totally damaged.
W: You usually park your car around there, don't you, Bill？
M: Yes, I left it in that very spot a couple of days ago, but yesterday it was parked up the road.
W: You were lucky then, weren't you, Bill？
M: Out of luck, you mean! I'd be very pleased if my old ear were smashed to bits. I could claim from the insurance company then, couldn't I？
W: But you used to be so proud of your car, weren't you？
M: I used to be years ago, but now there are all sorts of repairs to be done, and I just haven't got enough spare cash to put it right.
W: You can always sell it, can't you？
M: Few people are stupid enough to buy a car in that state, are they？
W: The man whose car was crushed yesterday was very annoyed about it. He'll be given a new car by the builders, though.
M: Yes, but his car was a specially-built model that can't be replaced, and there was hardly anything wrong with it, was there？
W: Well, that's life! When people actually want to get rid of their cars, this sort of thing seldom happens, does it？
