Я очень много сериалов смотрю, оттуда знаю весь сленг и часть грамматики :)

BBC has English learning programs.

In China you can watch the news on CCTV in English or in Chinese. The reports are on the same topics, therefore the scripts (the content of the stories/reports) should be the same. If you have the same TV system in Russia, then I suggest you listen to the news in Russian, then listen to the same reports in English.

I watch news channels like CNN international & Aljazeera English that helped me to improve my English esp my listening skill.

To learn a foreign language, I think the most help is to choose the crowd, what to learn to speak what language of language, so that is together soon, is also a big help, and China have something called "howl" try, believe that you can feel the general effect! To understand to understand from confused...... I wish you to learn well.
