In China，safety education is becoming more and more important.Stampedes（蜂擁），earthquakes and fires are the main accidents at school.Students need to learn about how to keep themselves safe at school.
    Stampedes often happen in crowded places.When the people begin to push you，you should stand there and hold something.If you fall down in these crowed places，you should protect your head with your hands.
    Earthquakes always happen suddenly.If you are inside a building，you can hide under a table or a chair，because it will protect you from being hurt by the falling things.If you are outside a building，you should find an open place and stay away from buildings and trees.
    When there's a fire，leave the classroom as soon as possible.While leaving the classroom，you'd better put something wet over your mouth and ears.In this way，you won't take in the smoke（煙）.In fact，many people die in a fire just because of the smoke.The smoke is full of CO?（二氧化碳） and that makes it difficult for people to breathe.So you should make yourself close to the floor and try to go out quickly.Then you will be safe and you can breathe the fresh air.
