Nowadays, students’ safety has become a big problem. As students, we should know how to protect ourselves. So, Mr. Li, a teacher from Zhangjiajie, gives us some advice on how to deal with danger.
★If you are in a traffic accident
If a car hits you, you should remember the car number. If it is a bicycle, try to call your parents before you let the rider go. That’s because you don’t know how seriously you are hurt.
★If it is raining hard and there is lighting
Don’t stay in high places and stay 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). Don’t take the lift.
★If someone is drowning(溺水)
If you can’t swim, don’t get into water. Cry out for help. Remember that danger is never as far away as you think. Take care of yourself at all times.
★If you are robbed(打劫)
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 later.
