Personally the first time I have advanced in English in school when I was fond of tricks, and I got a great book about tricks in the English language. I had nowhere to go, sitting with a dictionary and translated. The second big step was taken with the tutorial, good tutorial, though somewhat old. Also sat and taught each evening. In addition, I note the book "English for ours" and movies in English but it would be good to pick up, and I think often to review. And accidentally read the very sensible advice — do not believe it — from the newspaper "Soviet Russia", in relation to the articulation of a position, as a result, the American, who I studied a year on the course, said that I have the best pronunciation out of all he heard), the Council is quite common, but nevertheless — in the Russian language sounds are formed mainly in front of the mouth, and in English — in the middle. Even if you know the language well and carefully pronounce all sorts of r, th, etc., but articulation position you are Russian, you will have a distinctive and recognizable Russian accent.
