　　At Harton College－an English boarding school for boys, there are many rules．15-year-old Bob Sanders often breaks them．

　　The boys can go into the town in the afternoon after class．But they must retum to the school at six o'clock, One afternoon Bob walked to the town．He looked at the shops and then went to the cinema．After the film, he looked at his watch．It was after eight o'clock．He was a little worried．He walked back to Harton College as fast as possible．

　　When he arrived, he ran quickly to the main entrance．It was locked．He went round the school building to another door, which was locked too．He looked up at the window of his dormitory on the third floor．The window was open．But it was quite dark and he could not climb up the wall easily．Then he saw another open windows on the ground floor．It was the window of the headmaster's study．

　　He looked into the room－no one was there．Bob quickly climbed on to the window sill(窗台)and jumped into the room．Just then he heard a noise．Then someone turned on a light in the corridor．Bob looked around and then hid under the sofa．One minute later, Mr．Mannering, the headmaster, came in．He turned on the light on his desk, and sat down on the sofa．Then he opened a book and began to read．

　　Bob lay under the sofa as quietly as possible．He couldn't move．The floor was cold and uncomfortable．He looked at the headmaster's shoes and socks for an hour．

　　“Why doesn't he get up and go to bed?”Bob thought．

　　Mr．Mannering read his book for an hour．Finally, the headmaster closed his book and stood up．He put the book on the shelf and walked towards the door．

　　“Thank heavens he didn't find me under the sofa,”thought Bob．

　　Then Mr．Mannering stopped and spoke towards the sofa．“Would you turn off the light when you leave?”he said, and left the study．
