There was once a bad king，all his people hated him very much．One day in a summer he was swimming by himself in a river．

　　The king was a good swimmer，but while he was in the middle of the river，he was ill．He cried out“Help！Help！”At that time two farmers were working in the field near the river．

　　They ran over，jumped into the water and saved the king．They didn't know that he was the king until they pulled him our of the water．

　　The king was very happy，so he said to the farmers，“You have saved my life．Now you may ask for anything，and I'll give it to you．”

　　One of the farmers said，“My son broke his leg last week，and he can't walk．Please send him a good doctor．”The king agreed．Then he said to the other farmer．“And what can I do for，old man？”

　　The old man was very clever．He thought for a few minutes and then he answered，“You can do a very important thing for me．”“What's that？”asked the king．He thought that the old man would ask for some money or something else．

　　“Don't tell anybody that we have saved you，”the old farmer answered．
