Dear Sir,
I'm writing to request to be the host family for the British student who will pay a visit our school．
Firstly, my house is large enough to serve another people．Meanwhile, my father will drive private car to take him anywhere he likes．That is to say, not only I but also my father are ready for his coming．Secondly, I can speak English fluent and I am eager to communicate with foreigners, that is a good way to improve my English．Finally, last year I stayed with a British student for a week．So precious is the memory to us all that we have kept writing to each other since then．I will appreciate this if you could give me the chance．
I'm looking forward to receive your early reply．Please write to me when convenient．
