How to keep safe?
As teenagers, we should always keep safety in mind. But how can we keep safe? Here are some of my 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 ought to eat healthily and safely. Eating food that goes bad will do harm to our health. Last but not least, summer is coming, and we must remember it's dangerous to swim in the river.
In short, safety must come first!

作为青少年，我们应该时刻牢记安全。但我们怎么才能保证安全呢？以下是我的一些建议。
首先，我们交朋友时要小心，尤其是在网上。第二，如果我们处于危险之中，我们必须及时报警，以确保我们自己的安全。此外，我们应该吃得健康安全。吃变质的食物会对我们的健康有害。最后，最重要的是，夏天即将来临，我们必须记住在河里游泳是危险的。
总之，安全第一！
