Thank you if you could tranlaste the two sentences above to English
sorry not english i mean Russian language.

From, Russian,German,French,Spanish and Italian?

Also, please give me some, very simple Russian phrases or sentences or anything easy and interesting to catch/remember!

I'm from a Russian speaking family but grew up speaking English as my first language. Lately I've been studying written Russian more formally and have been speaking/reading it for hours at a time. I've started to notice that after I've been immersed in Russian for a while, my English isn't as great as it normally is. Words don't come to me as easily and my sentences sound awkward. I write for a living and it's becoming a problem. Has anyone else experienced this?

Does anyone know a good website to learn Russian?

I've been wanting to learn Russian for some time now, and I already know the fundamentals (verb aspects, comparative, adjective and noun cases, verb tenses, word order in sentences, reflexive verbs, telling the time, etc.), but I hardly heard it spoken and I was wondering if anyone could recommend a site with spoken conversations (audio).
