I·m writing to request to be the 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 forigners,that ia 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.
