Sometimes fire is our friend. I can help us in many ways. But sometimes it is our enemy. It can be very harmful. Big fire can burn trees, houses, animals, or people.

Now we can make a fire easily with matches or lighters. Some children like to play with them, but matches and lighters can be very dangerous.

One match can burn a piece of paper, and then it could burn a house. A small fire can turn a big fire quickly.

Be careful with fire, and it will help us. But if we aren't careful with it, it may hurt us.

有时火是我们的朋友，它可以在许多方面帮助我们。可是有些时候它又是我们的敌人，它可能伤害我们。一场大火可能烧掉树木和房屋，动物，甚至烧死人。

如今我们能用火柴或打火机轻易地点火。有些孩子喜欢玩火柴或者打火机，可是它们是很危险的。

一根火柴可以点燃一张纸，然后可能烧毁一座房子。一场小火可以很快变成一场大火。

如果我们对火小心点，它会帮我们忙。如果我们不小心，它会伤害我们。
