初中英语 A happy man

The Beijing Olympic Games is being on now.Several hours ago, I watched a tennis game of women on TV.It's between Chinsese and Russia.In the middle I often saw a young man running across the ground again and again.I was amazed about that.At last I know What he was doing.He was picking up the tennis balls.

Maybe nobody would pay attention to the man ,but he was working hard,for the Olympic Games.I think he must be a happy man.
