阅读理解。 One day an Indian went to see his doctor. The doctor looked him over and said, ' Medicine won't help you. You must have a good rest. Go to a quiet place for a month, go to bed early, drink milk, walk a lot, and smoke only one cigar (烟) a day.' A month later, the Indian came to see the doctor again. 'How are you?' said the doctor. 'I'm glad to see you again. You look much younger.' 'Oh, doctor. I feel quite well now,' said the Indian.'I had a good rest. I went to bed early, I drank a lot of milk. I walked a lot.
