　　How Can We Protect Ourselves

　　Self-protection is one of the most important skills for teenagers. But how can we protect ourselves? Here are some suggestions.

　　First, we should be careful when we make friends, especially on line. Second, if we are in danger, we must call the police for help in time so that we can keep ourselves safe. Also, we should eat healthily and safely. Besides, we shouldn’t crowd each other when we go upstairs or downstairs at school. Last, summer is coming, we must remember it’s dangerous to swim alone.
