听力原文：M: Hi, Laura. Where are you heading? W: Hi, Peter. Put off to the gym. I've got to stay in shape, you know. M: What's the main reason you work out? For your health, or to look good? W: To be honest, for both. With women, good looks are always a very important consideration. M: If you were honest, most men who work out would admit that they also do it to look better, and nut merely for health reasons. W: Do you get any regular exercise? M: I do a lot of walking, for exercise and enjoyment—sometimes ten to twenty kilometers at a time—but I never go to the gym like you do. W: Well, walking is good exercise. How about sports? M: Not since my school days. I used to love playing baseball, but it's impossible to get enough people together for a game now. Mostly I just watch sports on TV. W: I play tennis fairly regularly with my friends, and sometimes go swimming and cycling by myself. M: Oh, I forgot about that. I go cycling sometimes too. And I often go swimming on vacation, but only recreational swimming. W: Why don't you join me at the gym sometime? I can get you a guest pass. M: Well, maybe someday, but I'm pretty lazy about things like that. (20)
