A young man once went into town and bought himself a pair of trousers.When he got home,he went upstairs to his bedroom and put them on.He found that they were about two inches too long.
He came downstairs,where his mother and his two sisters were washing some things in the kitchen."These new trousers are too long." He said."They need shortening(缩短) by about two inches.Would one of you mind doing this for me,please?" His mother and sisters were busy and none of them said anything.
But as soon as his mother had finished washing up,she went quietly upstairs to her son's bedroom and shortened the trousers by two inches.She came downstairs without saying anything to her daughters.
Later on,after supper,the elder sister remembered her brother's trousers.She was a kind-hearted girl,so she went quietly upstairs without saying anything to anyone,and shortened the trousers by two inches.
The younger sister went to the cinema,but when she came back,she,too,remembered what her brother had said.So she ran upstairs and took two inches off the legs of the new trousers.
