Fire can help people in many ways. But it can also be very harmful(有害的). Fire can keep your house warm, give light(光)and cook food. But fire can burn(烧)things, too. Big fire can burn trees, houses, animals or people.
Nobody knows how people began to use fire. But there are many interesting old stories about how a man or woman started(开始)a fire. One is about a man. The man lived very long time ago. He went up to the sun and brought fire down.
Today people know how to make a fire with matches. Children sometimes like to play with them. But matches can be very dangerous(危险). One match can burn a piece of paper, and then it could be a house. A small fire can turn a big fire very quickly. So you must be careful with matches.
Be careful with fire, and it will help you. But if you aren't careful with fire, it may hurt（伤害) you.
