     A LONG time ago, there was a big apple tree. A little boy liked playing around it every day.

     As the little boy grew up, he no longer played around the tree.? One day the boy came back to the

  tree. He looked sad.

     "What's troubling you?" asked the tree.

     The boy replied (回答): "I want my own house. I need money to buy it."

     "You can pick my apples and sell them. Then you will have money."

     The boy was so excited. He picked all the apples on the tree and left happily.

     A few years later, the boy returned. He told the tree that he wanted to go sailing around the world."Use

  my branches (树干) to build your boat. You can sail far and be happy." So the boy cut the tree branch to

  make a boat. He went sailing and didn't return for a long, long time.

     Many years later, the boy returned. "Sorry, but I don't have anything for you anymore," the tree said,

 crying.

     "All I need is a place to rest. I am tired after my travels."

     The tree replied: "Good! Old tree roots are the best place to rest." The boy sat down and the tree was

  glad.
