Mr.White works in a middle school .There he teaches PE .He works hard and wants some of his students to be famous players ,but he fails .He’s often sad for it .He has a five-year-old daughter ,Mabel .The little girl is tall and strong .He places hopes on her .Every morning he makes her get up early and do morning exercises with him .The little girl is often tired but she has to do so .There was a sports meeting in their school last week .Mabel came with her father and watched the high jump ,the long jump and the relay races .But she liked to watch the 100-meter-races best .That evening she went home happily .She talked with her father about it at supper .“Why did the children run like hell ?”asked Mabel .“Because we rewarden the child who was the first to pass the finishing line .”answered Mr.White .“What did the other children run for ,then ?”was the second question .谢谢啦
