dear mr. brown,
i’m very grateful to have received the money and books you sent me. i couldn’t have returned to school without your help. thanks a lot. i have been working hard since i went back to school. i have made great progress in my studies with the help of my teachers. they often praise me and encourage me. without your help, i might have left school and couldn’t have got such a good education. i have made up my mind to study harder and make greater progress.
