听力原文：M: Hello. How are you today？

W: Not so good. My leg's playing me up. Awful pains in my leg and my toothache!

M: Oh, dear! I've got toothache too and the dentist says he simply can't see me before next week. But what gets me is my headache.

W: I know what you mean, but at least you can do the garden. I can't even do that with my back — the doctor says I mustn't lift or bend.

M: You poor thing. There's nothing worse than back trouble. But I don't do much in the garden now because I've hurt my ann. It's really painful.

W: Like my ankle. It's all swollen up.
