Dear schoolmates,
As I am graduating, I'd like to write this letter to express my feelings before leaving school. As for me, it is the school life that colors my daily life. During the three years, I had a good time with teachers and classmates who were in favor of me. Besides, there is no doubt that I achieved lots of knowledge and skills which are good for my future study.
Nevertheless, there are also some things that I regret about. For instance, wasting too much time playing computers, I spent a little time in studying. Moreover, I regret arguing with my friends when I was in a low spirit.
Gone are the days when I studied in high school. Needless to say, there are many challenges in university where I will start my new life. Therefore, I should make every effort to study in university.
Here is some advice for you to take. Under no circumstances should you waste time doing things that aren't linked with study. Apart from this, it's high time that you should spare no effort to get good marks at school.
Good luck to all of you!
Yours

亲爱的同学们，
在我毕业的时候，我想写这封信来表达我在离开学校之前的感受。对于我来说，正是学校生活给我的生活带来了色彩。在这三年里，我和老师和同学们相处得很愉快，他们都支持我。此外，毫无疑问，我获得了许多知识和技能，这对我以后的学习很有好处。
不过，也有一些事情，我很遗憾。例如，浪费太多时间玩电脑，我花了一点时间学习。而且，我很后悔和我的朋友在我情绪低落的时候吵架。
我在高中学习的日子一去不复返了。不用说，在大学里有许多挑战，我将开始我的新生活。因此，我应该尽一切努力在大学学习。
这里有一些建议给你。在任何情况下你都不应该浪费时间去做与学习无关的事情。除此之外，到了你应该不遗余力地在学校取得好成绩的时候了。
祝你们好运!
你的
