Dear Mr.Headmaster:

尊敬的校长先生：

I am Li Yue, a student from Class 1, Senior 2. I am writing to draw your attention to some improper behaviour among us students: littering and scribbling. It makes our school dirty and unpleasant, and does harm to the image of our school. I always feel ashamed when-ever I see this. It is clearly not appropriate for a student to litter and scribble.

我是高二（1）班的学生李玥。我写信是想提醒你注意我们学生的一些不当行为：乱扔垃圾和乱写乱画。它使我们的学校变得肮脏、令人不快，并损害了我们学校的形象。当我看到这一切时，我总是感到羞愧。学生乱扔垃圾和乱涂乱画显然是不合适的。

I wonder if the school could place more dustbins around and set up specific rules against such behaviour. At the same time, students should be encouraged to develop good habits and better behave themselves. Believe that, with the Joint efforts of both teachers and students, our school will Become a more enjoyable place in the near future.

我想学校是否可以在周围放置更多的垃圾箱，并制定针对此类行为的具体规则。同时，应该鼓励学生养成良好的习惯，更好地表现自己。相信在老师和学生的共同努力下，我们的学校将在不久的将来成为一个更令人愉快的地方。

Thank you for your consideration.

谢谢您的考虑。

Yours faithfully(用于正式信函的末尾，署名之前), Li Yue

您忠实的,李越
