求英语作文：假如你叫张华,在光明学校读书,给你的美国笔友Tom写一封电子邮件,介绍你三年在学校的学习

Dear Tom,
As i will finish my high school this July, i'd like to tell your a very impressive issue during my school life. That's the time my classmates and i went to the review lessons in the classroom every night. I think it's the happiest moment during a whole day. We would finish doing our homework by ourselves at the beginning, then we would negotiate over the difficult questions and help each other. My friends are very kind-hearted persons, they did not hesitate to help me whenever i have problems. At 9 PM in the evening, we will go back to the dormitory building with a light heart, gossiping interesting topics and singing pop musics together. I love my high school life very much.
Yours truly,
Zhang Hua
