Saturday morning was bright and fresh. There was a song in every heart, cheer on every face, and a  spring in every step.
Tom appeared with a bucket of white paint in one hand and a brush in the other. His Aunt Polly told him to paint the fence around the garden. It was thirty yards long and nine feet high. He felt very depressed.
Then he had a wonderful idea. He picked up his brush and started to work.
Soon Ben came along the road. He was happily eating an apple. He stopped to look at Tom. Tom went on painting and pretended（假装）not to see Ben.
“I’m going swimming,” said Ben. “Do you want to go swimming, Tom? But I guess you can’t. You have to stay and work, don’t you?”
“Work?” Tom said. “This isn’t work. I’m enjoying myself. Does a boy get a chance to paint a fence like this every day?”
Ben  thought  about  this.  Tom  continued  painting  carefully. Sometimes he stopped, stood back to look at the fence like an artist, and then added a bit more paint in just the right place. Ben was watching Tom paint with great interest. He was getting more and more eager to have a try himself.
After a while, Ben asked Tom if he would let him paint a little. Tom thought about it, and said,
“No, Ben, I can’t. You see. Aunt Polly wants it to be done well. Aunt Polly said that I must paint it with great care.”
“Oh, please, Tom,” begged Ben. “I can do it. I’ll be really careful. Just let me try. I’ll give you half of my apple. Well, I’ll give you all of it!”
“Well, all right, Ben,” said Tom. “You must be very careful.”
He gave Ben his brush with worry on his face but joy in his heart. He sat down under the tree, and started to eat Ben’s apple. All day, boys came to make fun of Tom, but they ended up staying to paint. When Ben got tired, Billy was waiting. He gave Tom a kite for a chance to paint. Then Johnny offered him twelve marbles, and so on.
By late afternoon Tom had gained all sorts of toys, and the fence had gained three  coats of paint. Later Aunt Polly came to look at the painted fence. She was so pleased with Tom’s work that she gave Tom a large cake!
【小题1】Why did Tom pretend not to see Ben when he came and watched him painting?
