What makes fire burn? Fires need both fuel and oxygen to burn. Some types of fuel are wood, oil, and coal. Oxygen is a gas in the air. The more fuel or oxygen there is, the hotter the fire will burn. Fires can be stopped in three ways. One way is to remove the fuel. A second way is to smother the fire by removing its oxygen. A third way is to remove the fire's heat with water.

火是怎么燃烧起来的呢？ 火燃烧需要燃料和氧气两种东西。 常见的燃料有木材、汽油和煤炭。 氧气是空气里的一种气体。 燃料或氧气越多，火燃烧的温度就越高。 我们有三种方法可以灭火。 第一种方法是移走燃料。 第二种方法是隔绝氧气来闷熄大火。 第三种方法是用水带走火的热量。
