Section     A

Old John went to see a doctor. The doctor examined him and said， Medicine can’t help you much. You must have a good rest. Go to a quiet place for a month. Remember to go to bed early, drink some milk, walk a lot and smoke one cigar a day. ?"

"Thank you very much. I will do everything you say，” promised Old John.

A month later Old John went to the doctor again. “Well，” said the doctor，“I’m glad that you look much younger now.

“Oh，doctor，” said Old John，I feel quite well now. I had a good rest. I went to bed early, I drank a lot of milk, and I walked a lot. Your advice certainly helped. But you asked me to smoke one cigar a day, and one cigar a day nearly killed me at first. It’s no joke to start smoking at my  age.
