     I live on the twelfth floor of a building. One afternoon I was coming home from a friend's house. It

was just after 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, half way up, it suddenly stopped between two

floors. I couldn't understand it. I pressed all the buttons from 1 to 14. I called for help very loudly. But

nobody answered.

      Then suddenly the light went out, and I 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. Then, I felt hopeless, and pressed all the buttons with

my open hands. And all at the same time, there was a bell far away. It rang and rang. It was the fire

alarm (火灾警报). I thought the whole building was on fire. I said to God quietly, "Just get me out of

here. I'll never be bad again."

     Just then, I realized the lift was moving very slowly. On the ground floor it stopped, and the doors

opened. A man was standing there. "How long have you been in there? It is good that you pressed the

alarm bell. But haven't you learned to read at your school?" He pointed at a small piece of paper on the

wall beside the lift. It said:

     "Attention: This lift will be stopped for repairs between 4pm and 5 pm on Thursday March 13."
