Dear schoolmates,

First, we shouldn't climb trees or windows. It's dangerous.
Second, don't jump from the stairs, because we may fall down or hurt others. Third, let us not run in the classroom. We may hit desks, chairs or our classmates.
Last but not least, we shouldn't stand on the chair to get the book. It's easy for us to get hurt. Let's keep safe at school.
