精明的家庭主婦

　　A smart housewife was told that there was a kind of stove which would only consume half of the coal she was burning. She was very excited, and said: "That'll be terrific! Since one stove can save half of the coal, if I buy two, no coal will be needed!"

　　一位精明的家庭主婦聽人說有一種爐子用起來可以比她現(xiàn)在用的爐子省一半的煤。她聽了大為興奮，說：“那太好了!一個爐子可以省一半的煤，那么如果我買兩個爐子的話，不就可以把煤全都省下來了嗎?”
