     Once upon a time there lived a rich man and a poor tailor (裁缝) in the same house. The rich man lived

upstairs and the poor tailor lived downstairs.

     The tailor liked to sing when he made clothes. He sang one song after another. But the rich man liked to

sleep a lot, and the singing made him angry.

     One day, the rich man said,"Tailor, I will give you a bag full of money every day if you stop singing."

"Fine,"said the tailor. And so the tailor stopped singing and became richer and richer. But the more money he

got from the rich man, the unhappier he became. Because he wanted very much to sing again.

     At last he brought all his money back to the rich man."Here,"he said,"Take your money back.I won't be

happy if I can't sing."And so he gave the money back to the rich man and went away singing. He sang and

sang and was happier than ever before.
