Dear Mathew, On behalf of all the students in our shcool, I am writing to congratulate you about the great teachong work you did. We think you are knowlegeable and you are always patient with us.Besides, how delighyed we are in you class. And we are affect with you. However,ther are some students who are poor in Eniglish. So,there are some advice I give for you to make them improve soon. First,we can communicate with them in English so that they would not foget quickly. Second,some english contests are helpful for them. I suppose by helping of us,they can improve soon.
