По английскому?

Dear (имя кому пишешь),

Thank you for your letter. It was great to hear from you again. Sorry, I haven’t written to you for a long time, because I was busy.

Well, my name is (твоё имя). I am (возраст). I live in (город, страна). I am in the (номер класса) class. My school is (номер школы).

By the way, it would be great to know about you and your family. How old are you? What is you mother and father? Do you have a sister or a brother?

That’s all for now. I have to go. Write soon, I will be waiting for your answer.

Best wishes,

(Твоё имя, без точки)

Надеюсь я не ошиблась. Удачи.
