Эээ, на английском же надо, да?
Dear Ded Moroz,
Thank your for my New Year presents, I really enjoyed them.
I am writing you to let you know, that I have finally understood how much I love my school. I think that my school is the best all over the world, and I want it to become better and better. I want my teachers to get more money for their working, because they worth it, want my classmates to become cleverer, although they all are bright, want our classrooms to become more comfortable aand so on.
I hope You will help our school in everything, thank you.
With best wishes
твое имя.
