On Saturday morning, everyone is happy but Tom is sad. He sits and says "Too bad! It's a nice day. But I have to paint the fence(栅栏). "Suddenly(忽然), he has a good idea.
Tom's friend Ben comes and eats an apple. He says "Tom, I'm going swimming, but you're working."
"I can go swimming every day, but I can't paint a fence every day. I like it!" Tom says. Ben is surprised(吃惊的). He wants to paint too. "Tom. Let me paint a little. "Ben says.
"I'm really sorry. It's my work. "Tom says.
"Oh, Tom. Let me try, please!" says Ben. "Here, you can eat my apple."Tom is happy. "Fine. Ben, you can paint for a short time. "
Then Tom's other friends come. They all want to try. They give Tom a new kite, a cat, a key and more. Tom's friends paint. Tom sits and thinks, "When something is difficult(困难的) to get, everyone wants it."
