I’m writing to tell you something   Nobody likes to be   However, some students throw waste paper and bottles    We all need a quiet place to study, but some students often make too much      at school. Even    , some of them are quite rude when talking to others. Everybody knows their behavior is bad, but    of us knows how to stop them.
I think we should make rules to     the situation. Perhaps it will be hard for us to obey the rules in the    , but if everyone does      best to follow the rules, our school will become better and better day     day.
Sincerely,
