Fire can help people in many ways, but it can also be dangerous. Fire can keep you warm, give light and cook food. However, big fire can also burn your house and hurt you. Nobody knows how ancient people started using fire. Today, people can make fire very easily. They use matches and lighters. Sometimes children like to play with them, but it can be very dangerous. One match can burn a piece of paper, and a small fire can start a big fire to burn everything. So you must be careful with matches. If you use the fire in the right way, it can help you, but if you use it in the wrong way, it may hurt you（初中英语作文 www.lyy5.com）.
翻译：
火可以在很多方面帮助人们，但是也可以非常危险。火可以让你保持温暖，发出光亮以及煮饭。然而，大火也可以将你房子烧掉，伤害到你。没人知道古人是怎么开始使用火的。今天，人们很容易就可以生火。他们用火柴或者打火机。有时候小朋友喜欢玩火柴，但是这十分危险。一根火柴可以燃烧一张纸，而小火可以引起一场大火烧掉一切。所以你要小心火柴。如果你用正确的方法使用火，它就可以帮助你，然而如果你用错了它，它可能会伤害到你。
