Dear Sir，
    Thank you for invite me to the summer English course in your school．As for your choice between the two courses，I prefer the four-week course because of this will allow me more time to do some traveling but make a few new friends．Of all the subject I'm learning at school，I like English best．I had been learning English for eleven years but my spoken English remains poorly．So I really hope to take this chance improve it．If possible，I'd like to stay with a family for a couple of days in order that I can know some customs in England，that I'm particularly interested in．I believe I will have wonderful time this summer．
Yours truly．

1．invite-inviting    考查动名词．介词for后面接动名词invite----inviting
2．your choice-my choice，考查人称代词．文中作者在叙述自己的选择，而不是其他人的选择，所以用my choice．
3．because of-because  考查原因状语从句的连词．because of后接名词或名词短语，because 后接完整的句子，句中是完整的句子，所以去掉of．
4．but--and 考查连词． 前后之间的关系是并列关系，所以用and．
5．subject-subjects，考查名词单复数． subject是可数名词，前面有all修饰，所以用复数形式．
6．had been-have been   考查时态．本文上下文用的是一般时态，这里要表示完成时态，则需要用现在完成时态．
7．poorly-poor   考查形容词，remain是系动词，系动词后应该用形容词作表语．
8．chance 后加 to 考查不定式． 句中用不定式表示目的．
9．that-which 考查定语从句，本句中含有非限制性定语从句，that不能引导非限制性定语从句．所以用关系代词which．
10．have wonderful-have a wonderful  考查冠词搭配． have a  wonderful time固定短语，意思是：玩得愉快．
