Fires are very dangerous.   . Knowing some ways to protect yourself will help to keep you safe in a fire.
If you are indoors, you need to get outside quickly and safely. First, you must turn off the gas and the electricity in the room.    . You should cover your mouth with a wet towel(毛巾) or something wet, because there must be thick smoke with the fire.   .
And you should try to keep your body down to the floor. If you feel the door hot, don’t open it,      .
If you can’t run away from the fire at once, just stay in a safe place, waiting for someone to help you. Remember: never jump out off the house.      . You should wave your hands out of the window for help.
