It's true that three-roommates from the US had an amazing discovery(发现). They paid $20 for a sofa from a store.
One night, they were sitting on the sofa and felt something must be in the sofa. Mr Werkhoven opened one part of the sofa and found an envelope(信封)with around $ 4, 000 in it. The roommates started opening other parts of the sofa, and kept finding more envelopes. At last they found over S 40, 000 in the sofa.
At first, the roommates said that they were very excited. They said they even started to talk about how to spend the-money. But then the roommates found a phone number on one of the envelopes. The next day, they called the person to say what they had found.
The owner was a 91-year-old lady. She put the money in the sofa. However, her family did not know about the money and gave the sofa away.
The roommates drove to the woman's house to return the money. When they gave the money back, the old woman cried and gave the three roommates $ 1, 000 to express thanks. Miss Guasti said that they thought about keeping the money at first, but they knew that they would have felt wrong to use it,
