　　One day,an old woman wanted to go to London to see her daughter．She got up early and got to the small station at nine o'clock in the morning．Because this was her first trip to London,she didn't know the train time．At that moment(时刻),she saw a boy．She stopped him and asked him what time the train would arrive at the station and when it would leave for(出发去)London．

　　The boy looked at the woman and said “tu tu tu,tu tu”,just like firing a gun(放枪)．Then he ran away．The old woman was very surprised and got angry．She sat on a chair and thought about the boy's words．Then she began to smile．She could not help(禁不住)crying out,“What a clever boy!He told me the time in such(这样的)a way．”Do you know the time?
