Dear Jim
I'm glad to receive your letter,and I want to tell you something about my study. My English is much better than before. With my teacher's help, I have made great progress. I take notes in class and review the lessons after class. My English has improved a lot. In my opinion,'there is nothing different if you put your heart into it'.
I will work harder than before,and I think my English will improve more.
Yours
Li Ming
