Being safe at school and in your everyday life needs knowledge.If you remember the following advice，your life will be safer.
    You should think it over by yourself when you meet trouble at school.If you don't know how to solve it，you may ask for help from your teachers or classmates.
    If you cannot swim，don't get into the water.Shout for help if you drop in the water.Look after yourself all the time.
Don't play with matches（火柴） or candles（蠟燭），because they may cause fire.If your house catches fire（著火） and you have to run away through smoke，move on your hands and knees with your head 30-60 centimeters above the floor.Remember there's cleaner and cooler air near the floor during the fire.
    If you are hit by a car，remember the number of the car.And then call the police or your parents right away.
    You must lock（鎖?。?the door inside and close the window when you are at home alone.You should put the mobile phone near you.Never open the door when you hear someone knocking at the door because your parents have the keys and they know your phone number.
