听力题 M: So what''s your trouble? W: Well, doctor, I haven''t been feeling well lately. My biggest problem is that I''m having trouble sleeping. M: Have you tried any of the sleeping medications available? W: I''ve tried one or two, but they don''t seem to help. M: How long have you had this problem? W: About half a year—it''s been rather a long time now. M: Are you suffering from an unusual level of stress in your life lately? W: Not more than usual. My biggest worry is the fact I can''t sleep. M: Well, some people don''t need as much sleep as others. W: But I feel tired all day, so it is a problem for me. M: Have you been experiencing any other symptoms? W: I''ve also had a lot of indigestion lately. M: Well, you are a little overweight, aren''t you? W: Yes. And I''ve gained about seven kilograms this past year. M: You really should try to lose at least that extra weight. Do you get much exercise? W: No, not very much. M: Physical activity is very important. W: So what do you recommend, doctor? M: I will give you some medication for your insomnia and your indigestion. But I also recommend that you begin a regular exercise program. W: But I have neither the time nor the money to go to a gym. M: You don''t need to go to a gym. A simple walking program would be very beneficial for you. I think you''ll find that diet and exercise will be very helpful in taking care of your recent complaints.
