Dear Fang Pin，

My brother and I are in the same school now． We have classes from Monday． tqFriday． on Saturday and Sunday， we don-t have any classes． We have many American friends now． We often play games together after school． They help us with our Eng-lish， and we teach them Chinese． They like China and want to go and have a look some day． On Sunday， we go to shops with mother． Father and mother sometimes take us to other places． American people are very friendly to us． How many English classes do you have every week? Do you like it?

Please write to me soon．

Yours，

Zhao Hai
