　　One day an American went to a small town in South America for his holiday.

Few people went there because it was far away from the cities．He felt ill(生病) and wanted to see a doctor very much．

　　The American went to find out how he could find a fine doctor there．A man told him，“That's very easy．If there is a patient(病人) that a doctor can't cure(治愈)，the doctor has to put a balloon over his clinic(診所)．”

　　The American thought，“The fewer balloons there are，the finer the doctor is．”He began to look for the finest doctor along the street．First he found a clinic.There were 20 balloons．After a few minutes he found another one?0 balloons.He thought neither doctor was fine．

　　At last he found the third clinic．Only 5 balloons were there．He was very happy and went in．

　　“Wait a minute，”said the doctor，“I'm too busy，you know．This clinic opened only yesterday．”The American was very surprised(感到吃驚) and said to himself， “Where can I find the finest doctor?”
