高三的英语题一道？急呀

Dear David Smith,
I'm LiHua, a student from XinHua middle school. I heard that a group of American students are coming China and want know more about Chinese culture. I know you are searching for suitable homestay family now. And I was attracted by the activity as soon as I read the news. So I am writing to you hoping to gain this chance to live in with an American student.
Now, please allow me make a brief self-introduction.
My family has 3 members. My parents and I live in different bedrooms. If a student were to live in my house, we could offer him a single room for sleeping. Both of my parents are teachers. They are in favor of my idea steadily. Moreover, I am not only interested in our Chinese culture but also like American culture very much. so I think that we will get along well with my foreign guest.
In order to introduce Chinese culture to him, I have made a plan. Firstly, the most important thing I will do is to teach him some useful oral Chinese. In this way, he will learn more about China with Chinese people, but not only by me. Secondly I am going to show him some famous scenic spots, where he can feel the Chinese culture by himself. I’m sure we will get together very happy.
Looking forward to your reply
Sincerely Yours,
LiHua
