听力原文：M: Well, madam, the first and the most important thing I have to tell you is that there is really nothing seriously wrong with you, physically that is. The analyst's report shows that basically you are very fit. W: So, why is it doctor that I'm always so nervy...tense...ready to jump on anybody—my husband, children, and colleagues? M: I think your condition has a lot to do with your habits. W: Habits? M: Yes...now tell me, madam, you smoke, don't you? W: Yes, I'm afraid I do, doctor. M: And, very heavily, I imagine. W: Yes, quite heavily. M: What do you eat normally? W: I'm a good eater. Yes I'd say I'm a good cater. But I usually, I don't eat breakfast. M: That's bad for your health. I think you should get up early and have breakfast. And, another question, do you get up early? W: No, I usually get up at 9:00. I get up late because I go to bed too late. I stay up late watching TV till the midnight. M: What sport do you usually do? W: I don't like sports. But sometime I play cards with some friends, that may be my sport. M: I think, madam, for your health, you'd better change your way of life. W: Could you tell me a bit about why you wanted to be a doctor and how you first got into the medical profession? (20)
