How to Keep Safe
Do you know that many dangerous things will happen if we are not careful enough? As a student, how to keep safe is very important.
First, we should obey the traffic rules. When the lights are red, we shouldn't cross the road. And we shouldn't ride the electric bicycles. Second, we shouldn't swim in the river because it's dangerous. We can go swimming with our parents in a swimming pool. Third, we shouldn't tell strangers our ID number or code when we are surfing the Internet. We shouldn't surf unhealthy websites. What's more, we shouldn't go out with friends without our parents' permission. If we are in danger, we can ask for help from our parents or teachers, even police.
After all, life is very important. We should learn something about self-protection so that we can protect ourselves well.
