My parents went to work and left my brother and me alone at home. I was doing my homework while my younger brother was watching television. Suddenly the doorbell rang. My younger brother rushed to open the door thinking that our parents came home.

Outside,stood a tall man wearing a black raincoat. He said that he was a salesman and asked politely if our mother or father was at home. Without thinking,my brother said,“No. ” He asked if we would like to buy some books,which he was selling. I  quickly explained that we were not supposed to buy anything without our parents' permission（允许）.

Then,as I was about to close the door,he forced his way into our house. He took out a knife and forced me to tie up my brother's hands with a rope which he took out from his pocket. I tied up his hands but I tied it in a special way. The man then tied my hands up and locked both of us in the kitchen.

Soon,he went upstairs to search the bedroom for valuables. I managed to teach my brother to untie the rope on his hands. He then untied me. I rushed to the telephone to call the police,but the line was dead. The doors were all locked from the outside and I did not have the keys to unlock them. Luckily,the robber（强盗）forgot to lock the kitchen window. My brother managed to get out of the house through the window and I told him to go to the neighbourhood police station and call for help. Of course,my brother brought the police to our house and the robber was caught.
