★ 范文
Dear students,
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.
Yours,
Li Hua
