  What a cold winter!How wonderful it would be if there was a fire!Fire keeps us warm. But fire is very dangerous and can kill us,too.

November 9th is National Fire Safety Day. It's a time for us to learn a lot more about fire,especially what to do if we are caught in a fire.

  Call 119.

  Never try to put out a fire yourself,even if it is a very small one!Get help from your parents or call 119. Tell 119 where you are and what is on fire. Listen to 119,s instructions. Keep down close to the floor.

  If there is a lot of smoke in your room,keep down close to the floor. There is less smoke down there,so it's easier to breathe(呼吸)and see where you are going. If you don't,the smoke may kill you before the fire does.

  Don't use the elevator.

  Never use the elevator during a fire. Always use the stairs. An elevator may stop at the floor where the fire is burning. It may also go wrong and keep you inside. Don't go back.

Never go back into a burning building ! Even if you have left your pet or favorite toy inside , do not go back for it. Don't worry about your pets. Animals have a very good sense of smell(嗅觉).They often get out of the building before people !
