       Once there was a boy in London. His name was Jimmy. He started painting when he was three years old,

and when he was five years old, he was already very good at it. He painted many beautiful and interesting

pictures, and a lot of people bought his pictures. They said, "This boy is going to be famous when he's a little

older, and then we're going to sell these pictures for a lot of money." 

painted on half of it, and the other half was always empty. 

       One day someone asked Jimmy, "Please tell me, Jimmy, why do you only paint on the bottom (底) half of

the paper, but not on the top half?"
