Chen Haoyu, a teacher at Beijing No.25 Middle School and a self-protection expert , gives young students advice on how to deal with danger. If you are robbed Keep calm. If you can not cry for help or run away, give the robber your money. Try to remember what the robber looks like and tell the police later. If you are in a traffic accident If a car hurts you, you should remember the car number; if it is a bicycle, try to call your parents before you let the rider go. This is because you don't know how badly you are hurt. If it is raining hard and there is lightning  Don't stay in high places and keep away from trees. When there is a fire Get away as fast as you can. Put wet things on your body and try to find an exit  . Do not take the lift! If someone is drowning   If you can't swim, don't get into the water. Cry out for help. Remember that danger is never as far away as you think. Take care of yourself at all times! The best title for the passage is  _  .
