One possible version:
How to Protect Ourselves as Teenagers?
Safety is very important. It's necessary for us teenagers to know how to protect ourselves. Here are some suggestions.
First, we should be careful when we are near places like rivers and lakes. These places could be dangerous, so we mustn't swim there. Second, if we are in danger, we must call the police in time so that we can get help as soon as possible. Third, we should obey the traffic rules and never play with our mobile phones when walking in the street. Last but not least, we shouldn't tell our personal information to strangers, especially online.
In short, we need to develop some basic skills of protecting ourselves. In that case, we can stay away from danger and live a peaceful life.
