The story took place in a small town in winter.One day a man met an old lady standing by an expensive car.It was clear that her car broke down.So he stopped his old truck and got out.Although he was smiling,the old lady was worried.“Is he going to hurt me?”

The man could see that she was frightened,so in his friendliest voice he said,“I'm here to help you,madam.Why don't you wait in the car to get warm? By the way,my name is Bryan Anderson.” It took Bryan about fifty minutes to fix the car.The lady felt quite thankful and she asked how much she should pay him.

But Bryan wanted no money.①对他来说,帮助别人很正常。He said,“If you want to repay me,next time you see someone in need,just give out your friendly hand.”
