身份的英语怎么写

这个是要你提供一份学生证明，要由系主任写，大致这样吧

Letter of Certification （证明信）

This is to certify that xxx, male, born on January 12, 1989, entered our university in September 2007. Mr. xxx is a computer science major. He has been a full-time student since 2007.

President of Computer Science School

如果没有系主任，就这样用计算机学院院长的身份

供参考

Dear Editor,

As we know environment is very important for us.But yesterday,I saw a factory in our city polluting one of our hometown's river by its dirty water.The grass and flower were all died because of the dirty water.I hope that you can report it in your newspaper,Time,to stop the factory from polluting our river

That's all

Yours truly

写得应该还可以吧？我也是高二的而已！水平差不多这样也符合你的要求吧？写得太好的未免太不符合实际了
