Long, long ago there was a very foolish thief. Do you know what he did one day? When he wanted to steal(偷) the bell on his neighbour’s door, he walked up to the door, took hold of(抓住) the bell and pulled hard. The bell made a very loud noise. The thief was afraid and went home.

Then he sat down to think, “I must do something about the noise,” he said. He thought and thought. At last he had an idea. “Ah, I’ll put some cotton in my ears. Then I won’t be able to hear the noise.” The next day he went to the door of his neighbour, and took hold of the bell. This time he pulled even harder. The bell rang loudly, but the thief did not hear anything. With another hard pull he got the bell out. Just then the neighbour came running out. “Steal my bell? I’ll teach you a lesson(教训),”the angry man shouted. And he hit the thief on the nose.
