| Jimmy began painting when he was three years old. When he was five, he was already very good at it. He painted 1 beautiful pictures and a lot of people 2 his pictures. They said, "This boy is going to be famous when he is a little older,and then we are going to sell these pictures 3 a lot more money." Jimmy’s pictures were 4 other people’s, because he never painted on all the paper. He painted on half of it, and the other half was always 5 . "That’s very clever,” everybody said. " 6 other painters did that before!" One day somebody bought one of Jimmy’s pictures and said to him, “Please tell me this, Jimmy. 7 do you paint on the bottom half of your pictures, 8 not on the top half?" "Because I’m 9 , " Jimmy said, " and my brushes don’t 10 very high." | |||
