Safety has become the focus to us all. How to be safe at school is especially important to us students. First, we should take care not to get ourselves injured while we are having sports. Second, There are too many students at school, and our hallways are too narrow. So don’t crowd with each other especially when we go upstairs or downstairs. Or there may be an accident. Besides, we should be friendly and get on well with others, don’t quarrel or even fight. Last but not least , We should be careful to eat healthy food and keep away from junk food, which is harmful to our health.
In a word, it's important to remember these for us all.
