I live on the l2th floor of a building．One day I was coming home from a friend's house .It was just about four o'clock，I got quickly into the lift and pressed button（按钮）12．
The lift started to go up，but very slowly．And then，halfway up，it suddenly stopped between two floors．I couldn't understand it．I pressed all the buttons from l to 14．I called for help loudly，but nobody answered．Then suddenly the lights went out，and l was alone in the dark．I started to cry and beat the walls of the lift．I cried and cried until I had no voice left For a long time I just sat on the floor and cried，I pressed all the buttons with my open hands all at the same time．Far away there was a bell，it rang and rang，it was the fire alarm（警报）I thought the whole building was on fire．I thought quietly．“Just get me out of here．”Just then，I felt the lift was moving very slowly．At the bottom（底部）it stopped，and the door opened．A man was standing outside．“How long have you been here? It is good that you pressed the alarm bell．But haven't you learned how to read and write at your school?’’ He pointed at a small piece of paper on the wall beside the lift．It said：“The lift will be out of order for mending between 4p．m．and 5p．m．on Tuesday，March l8．’’
