【正确答案】Dear sir,
I'm writing to request a valuable chance to be one of the host families for the Canadian students. There are following reasons. Firstly, Our house is large and clean and it lies in a beautiful area of the city, which makes the students live a comfortable life. Secondly, I am good at English and my parents also know some English, therefore, there is no trouble communicating with the students. What is more, we received two American students and we have a great time for all of us. Finally, my father is a great driver, who can show lots of places of interest in our town to the students and I'm sure they will have a glad visiting in our town. Besides, my mother cooks well, who can make them enjoy delicious Chinese food. I hope you can give me the chance to make friends with them. Looking forward to your early reply.
Yours,
