求一篇英语作文,中学水平,题目是:please write a letter to your teacher in junior school 拜托了!

Dear teacher,
I want to tell you something(tell sb sth结构) and I hope you can give me an answer.
Do you know how I want you to use me more than before? Though I'm not the best student in our class.As an Assistant monitor. I think I can do a lot ofthings for you. But you always don't let me do (let sb do结构)something. You always let the monitor and a girl that she studies better than me do everything. Just as(后面接句子用as, 往往不用like) I'm air. Do you know how I am(形容词前构成句子得加be动词, 所以加上am) sad? I can do it well.and (加上and表递进, 意思更通顺一些)I'm able to do it well. The most important(拼写错误) is that(后接表语从句得用连接词, 这里从句中不缺成分, 所以填上that)you know I can do it better than them and something should be done by me. But Ican't understand why you do not let medo anything (否定句中用anything)for our class. Maybe you will say you have to improve your result.But I don't think it will influence my result.Maybe I have let you(动词后用人称代词宾格) down. Because I speak in class sometimes.
I'm not playing a leading role in our class.I know.
So. I really need your answer to help and change me.
Thanksand best wishes
亲爱的老师,
我想告诉你（告诉某人某事结构）,我希望你能给我一个答复.
你知道我多么希望你用我比以前更?虽然我不是我们班最好的学生.作为一名助理监督.我想我能为你做很多事情.但你总是不让我做（让某人做结构）的东西.你总是让显示器和一个女孩,她学习比我做的一切.正如（后面接句子用的,往往不用像）我的空气.你知不知道我（形容词前构成句子得加是动词,所以加上分）伤心?我能做到well.and（加上和表递进,意思更通顺一些）我能做得很好.最重要的（拼写错误）是（后接表语从句得用连接词,这里从句中不缺成分,所以填上说）你知道我可以做得比他们更好的东西应该由我做.但我不明白你为什么不让我做我们班的任何东西（否定句中用任何东西）.也许你会说你要提高你的结果.但我不认为这会影响我的结果.也许我让你们（动词后用人称代词宾格）下来.因为我有时在课堂上发言.
我不是在玩我们班的主导作用.我知道.
如此.我真的需要你回答我的帮助和改变.
感谢和最良好的祝愿
