     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.
