       According to a new Ministry of Education (教育部) survey, student safety has become a big

problem. Nearly 50 percent of students say they are worried about robbery  on the way to and from

school. Now in many big cities in China, some school has taught an unusual lesson: self - protection

(自我保护). Students like this lesson as 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, gives young

students advice on how to deal with danger.

       If you are robbed

       Keep calm. If you cannot cry for help or run away, give the robber your money. Try to remember

what the robber looks like and tell the police.

       If you are in a traffic accident

       If you are hurt by a car, take down the car number; if it is a bicycle, try to contact your parents

before you let the rider go. This is because you don't know how seriously 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 and find an exit. 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!
