As we know safety is the most important thing in our lives. So we should try our best to make sure we are safe. We mustn't bring restricted knives or things to our school because these things may cause serious problems. Do not have a bath in rivers or ponds by ourselves without our parents' permission. And, we should be friendly to others so fighting is strongly banned. Make sure that we should always pay attention to the traffic on our way to school or home. Furthermore, if we meet some emergency, we must call for help from the police or our teachers. In a word, following these safeties rules above can make us live in peace.

How to Behave Well?
In order to build a civilized city, we students should try our best to behave well in the activities.
It's a good habit to keep our clothes clean and tidy. Our city should be kept clean every day. Don't throw litter or spit about. It's good manners to say "Thank you" and "Please" and so on. We should never say dirty words. Be friendly to others and always ready to help the people in need. For example, when we are on a bus, we should give our seats to the old and the women with babies. We should also obey traffic rules. When the traffic lights are red, we should stop. And we'd better not talk or laugh loudly in public.
If everyone behaves well, our city will be more beautiful and more attractive.
