One day Rip Van Winkle didn't want to work. So he went walking in the woods (树林) with his dog. He walked and walked. Then he sat under a big tree. There he met some little men. They danced and sang: "Come on, Van Winkle, dance and sing. "Rip danced all day with the little men. At the end of the day, he was very tired. He slept and he slept and he slept. When he got up, he couldn't find the little men.

Rip went back to the town. Everything was different! His house wasn't there! His friends weren't there! Rip asked, "Where is everyone I know?" A woman said, "Rip, you went away twenty years ago. Where did you go?" He told the story about the little men and his sleeping. "Rip," said the woman, "Look at your beard (胡须). It's all white."
