Hi, my name is erik. i live in a house in a small town in england. in my house there are there rooms downstairs and there rooms upstairs.

И как нам это преобразовывать? Если вам перевод нужен, то держите:
" Привет, меня зовут Эрик. Я живу в доме в маленьком городке в Англии. В моем доме (второе не there, а three) 3 комнаты внизу и комнаты наверху.

По всем правилам это: в правом верхнем углу пишем свой адрес, на строку ниже дата
Dear Daniel
I am writing to say thank you for your letter that I've just got. I hope all is well with you and your family.
 In your letter you told me about celebration of Thanksgiving in your country. You know, we don't celebrate such holiday in our country. But we have some other holidays that are celebrated in winter. The greatest one is New Year. And this holiday is best loved not only in my family but all over the country. This day we prepare holiday table, cook a lot of tasty things. Nothing special, but different salads and what not. We decorate the new year tree and wait for the midnight. When the clock strikes twelve, we drink for the new year and congratulate each other. Do you celebrate this holiday? If you do, tell me about the tradition of celebrating it in your country.
Well, I'm sorry but I really have to go now. I hope to hear from your soon.
Stay in touch and do write.Looking forward to hearing from you soon.

Love

Space exploration - the greatest idea of all time. Space - this is not only a unique laboratory where new materials and study the universe. Space - it is also the arena of the future distribution of mankind, to be exact - posthumanity. This is the material from which the distant future we can create our universe.

 

Освоение космоса - величайшая идея всех времён. Космос — это не только уникальная лаборатория, где создаются новые материалы и исследуется Вселенная. Космос — это ещё и арена будущего распространения человечества, точнее — постчеловечества. Это материал, из которого в далёком будущем мы сможем творить СВОЮ Вселенную.
