A young man once went to buy a pair of pants. When he got home, he went upstairs(上楼)to his bedroom and put them on. He found that they were two inches(英寸) long.

Then he came out of his room to see his mother and his two sisters. They were washing something in the kitchen.“These new pants are too long, they need to be shortened(缩短) about two inches.
