we are safe.
We mustn't bring restricted knives or things to our school because these things may cause serious prob-
lems.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.What's more,food safety is very important to us.We should not go out to eat
fast food.There are also some unsafe food in restaurants,such as unhealthy oil.
In a word,following these safety rules above can make us live in peace.
