A rich (富有的) man and a poor (穷的) musician (音乐家) lived in the same house. The rich man lived upstairs (楼上)and the poor musician lived downstairs (楼下). The musician liked to sing. But the rich man didn't like to sing, and he liked to sleep.
One day, the rich man said to him, I'll give you a bag of money every day if (假如) you stop singing.
“Fine,” said the musician. So he stopped singing and became a rich man, too. But he wasn't happy, because he wanted to sing again.
At last (最后), the poor musician said to the rich man, “Here's your money.
Get it back. I don't want your money, and I want to sing every day.” He started to sing again and he was happy again.
