2. 范文示例
How to Keep Safe
Safety is the most important thing for every person. We can never be too careful with safety. Here are some tips to help us stay safe.
First, we must follow traffic rules when we are on the road. We should wait for the green light before crossing the street, and look both ways to make sure there are no cars coming. When we ride bikes, we must wear helmets to protect our heads. Never play or run on busy roads, because it's very dangerous.
Second, we need to keep safe at school. Don't push or run in the hallway, especially when there are many students. We mustn't climb the school wall or play dangerous games during break time. If we get hurt, we should tell the teacher or go to the school clinic at once.
Third, we should be careful at home. Never play with fire or matches, because fire can easily start a big accident. We also shouldn't play with knives or sharp things, as they may hurt us. When we use hot water, we need to be very careful to avoid being burned.
Safety is around us every day. If we remember all these rules and tips, we can stay away from danger and live a safe and happy life.
