I would also like to add that watching feature films with subtitles helps a lot.
When I was in Sweden, I was very surprised by the fact that the whole population speaks English very well, a little less well in writing, but their spoken English is perfect. I asked - what methods are used in schools and colleges to learn English? I was very surprised with the answer - there is no special method in learning English, they just do not dub and translate absolutely all feature films and TV shows in this country. They are broadcast in English with Swedish subtitles. Thus almost the entire population speaks perfect English.
