Today people know how to make a fire with matches(火柴). Children sometimes like to play with them. But matches can be very dangerous.

This keeps the air away from a fire and kills it. Be careful with fire, and it will help you. Be careless with fire, and it will burn you. [br] When you are going to put out a fire, you( ).
