According to a new survey, student safety has become a big problem. Nearly 50% of students

According to a new survey, student safety has bee a big problem. Nearly 50% of students say they are worried about robbery(抢劫) on the way to and from school. Now in many big cities in China, some schools have taught an unusual lesson: self-protection(自我保护). Students like this lesson because there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No.25 Middle School and a self-protection expert(专家), 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(闪电)
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 (出口).
Do not take the lift!    
If someone is drowning (溺水)
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!
