听力题 M: Doctor, I just don''t know what''s wrong with me. I always feel tired and rundown. My wife finally persuaded me to visit you to find out what the trouble is. W: Looking at your case history I see that you had pneumonia four years ago and that you also had a minor operation last year. Did you have any long after effects? M: Well. I don''t remember so. . . W: For instance, how long did you stay at home each time? M: Just a couple of days. But about six months ago I was at home for about two weeks with a cold or something. W: Did you see a doctor at that time or did you just stay at home? M: No, I didn''t see a doctor. The symptoms were about the same as this time. When I began to feel better, I returned to work. W: And when did you start feeling so tired again? M: It must have been about ten days ago. When I came home from work one night there just didn''t seem to be any reason to go back the next day. W: Well, it sounds as if your problem may be the kind of work you do. The tests I just made really don''t show anything wrong. But I would like to make some further tests in the hospital. M: That''s fine with me. W: All right, you can check in tonight, and I''ll make the test tomorrow morning.
