谁帮我写一篇简单的英语作文

Dear Mr Smith,
My name is Wang Ning. I an a high school student in GanSu Province,I have a question to ask you.
Some of my classmates prefer British English ,so that they suggested me to speak British English.However,another part of my fellows enjoy speaking American English,in terms of this,I was advised speaking American English.
In my mind,I am not quite sure about what the differences between American English and British English and I find there's no way to tell them apart.Actually,I want to ask that how to tell the uncommon parts of the two kinds of English and which I should choose.
That's what I what to ask.
Looking forward to your return letter.
yours,Wangning
