There was a boy playing in the park. He saw a big tree in the middle of the park with a sign on it. The sign said, “I’m a magic tree. Say the magic words and then the door will open. You will see more magic.” The little boy tried many words, but the door didn’t open.
The boy was tired of trying, so he cried, “Please, dear, open the door!” The tree was happy to hear “Please” from the boy’s mouth. So a big door opened in the trunk of the tree! The tree said, “Polite boys always say magic words.”
What did the little boy do beside the tree? What other magic words did he say? Let’s read the great book by Peter Brown. Children will also enjoy the colourful pictures by the artist (艺术家，美术家), Andy Smart.
