Mr Smith was ill and he went to see a doctor. The doctor asked  him to put out his tongue(舌头), and then he said, “OK, You can put your tongue back now. There’s nothing wrong with you, but I’m afraid you have a problem. You hardly ever take exercise.”
  “But, doctor,” Mr Smith said, “I don’t think so.”
  “Don’t tell me what you think,” the doctor said, “I know    what you need. I see a lot of people like you. None of them goes  any exercise. They sit in offices all day and in front of the        television in the evening. You must walk quickly for at least(至少)20 minutes a day.”
  “I don’t want to hear any excuse(借口),” the doctor said. “You must find time for exercise. If you don’t, you will get fat and have health problems.”
  “But I walk every day,” Mr Smith said.
  “Oh, yes, and I know what kind of walking that is. You walk a few meters to the bus stop from your house, a few more meters from  the bus stop to your office, and a few more meters from your office  to your dining–room for lunch and back. That’s not a real walk.  I’m talking about a walk in the park or by the lake for twenty      minutes every day.”
  “Would you please listen to me, doctor? Mr Smith said, getting a little angry with his doctor.
  “I’m a postman,” Mr Smith went on, “and I walk for nearly(几乎)seven hours every day.”
  For a moment the doctor was silent(沉默的), then he said      quietly, “Put out your tongue again, will you?”
