| Fire can help people in many ways. But it can also be very harmful. Fire can heat water, warm your houses, give light, and cook food. 1. It can burn trees, houses, animals, or people. Sometimes big fires can burn forests. Nobody knows for sure (确实) how people began to use fire. But there are many interesting old stories about the first time a man or woman started a fire. One story from Australia tells about a man very, very long time ago. 2. Today people know how to make a fire with matches. Children sometimes like to play with them. But matches can be very dangerous. One match can burn a piece of paper, 3. A small fire can become a big fire very fast. Fires kill many people every year. So you must be careful with matches. 4. Fires need oxygen. Without oxygen they die. There is oxygen in the air. Cover a fire with water, sand, or in an emergency (紧急情况), with your coat or something else. This keeps the air away from a fire and kills it.
