Dear Headmaster,
尊敬的校长，
I'm writing to tell you something important.
这封信是想跟您说一些很重要的事情。
Nobody likes to be untidy.
大家都不喜欢脏乱。
However, some students throw waste paper and bottles everywhere.
但是，有些学生到处乱扔废纸和瓶子。
We all need a quiet place to study, but some students often make too much noise at school.
我们需要一个安静的环境去学习，但是有些学生经常在学校制造噪音。
Worst of all, some of them are quite rude when talking to others.
最糟的是，有些学生跟别人说话时很没有礼貌。
Everyone knows their behavior is bad, but none of us knows how to stop them.
大家都知道他们的行为不对，可是我们不知道该怎么去阻止他们。
I think we should make rules to change the situation.
我觉得我们应该制定规则来改善情况。
Anyone who breaks the rules will be punished.
任何不遵守规则的人都应受到惩罚。
Perhaps it will be hard for us to obey the rules in the beginning,
可能一开始让大家遵守规则有点困难，
but if everyone does his or her best to follow the rules, our school environment will improve.
但是如果每个人都努力遵守规定，我们的校园环境一定会有所改善。
Sincerely, Kangkang
真诚地，康康
