Dear Ben,
Thanks for your letter. It was nice to hear from you. Sorry, I haven't written for so long, because I was really busy. My favourite lesson is English, because I think it is a very helpful subject. You can chat with friends from other country and read a book in English. As for homework, I do it for about 3 hours daily except weekends.  After lessons I go to the  cafeteria, because food is really tasty there.Anyway, I have to go now, because my mum asked me to help her now.
Keep in touch.  Hope to hear from you soon.
Best wishes,
Nikita 

Дорогой Бен, 
за твоё письмо. Было приятно его получить. Извини, я  долго не писал, потому что был очень занят. Мой любимый урок - английский язык, потому что я думаю, что это очень полезный предмет. Мы можем общаться с друзьями из других стран и читать на английском языке. Что касается домашней работы, я делаю её около 3 часов ежедневно, кроме выходных.  После уроков я хожу в кафетерий, потому что там очень вкусная еда. Ну, а сейчас я должен идти, потому что мама попросила меня ей. 
Не теряйся. Надеюсь услышать от тебя ответ в ближайшее время.
С наилучшими пожеланиями,
Никита
