写一篇关于毕业前我们应该为学校做些什么的英语作文

Dear David, How's it going? I'm writing you this letter to tell you something about our discussion about what we should do before the graduation a few days ago. Some students suggested that we raise some money and buy some books for our library or some other stuffs. Other students said that there's no need to spend money, for when we graduate from the school with a good grade, the school would bbe proud of us. I think we should study hard, and meanwhile, we can plant some trees in our school to make it more beautiful. What do you think?
