Learn the language. Hi! I found a good technique for the study of language itself. I share it with you) This method is suitable for the study of English and Russian and any other language. I can advise you the following. Look for a small interesting or situational dialogues with text and audio. Sound necessarily native speakers. Texts do not have to be complicated. Instead, you have to understand 80% of what you listen to. Listen to every dialogue many times. Read the text, disassemble every word, every nuance of grammar and listening again, and then read the dialogue. When he was firmly in your memory with the next. Periodically go back and re-listen to the previous dialog. Greatly improves listening comprehension, pronunciation and speech (start using momentum of dialogue). Important - to have a player that allows you to put one track on repeat again and again. Second - read a lot. Read only what you are interested or need: sites of interest to companies, favorite books, forums, interest, etc. Reading is much more difficult hearing conversations, but very important. No need to memorize the words, because words are meaningless out of context, in Russian nuanced understanding of the same words .. First, it will be difficult to remember the words that come across in the texts. Will you watch the same word several times, but then there comes a time when the word is remembered for real, not as jagged as well as the meaning. Grammar is a good thing, a common understanding is necessary, but it does not need to cram, it is not an end in itself, its understanding of the image is brought to you by itself, when you begin to actively use the language. Sorry I do not have a systematic studies. I already knew the language perfectly ))
