Listening to English radio programmes help me get used to how fast native speaker talk. I also repeat what I hear to help me to experience the feeling of language. Sometimes I even record my voice so I can listen to my pronunciation and compare it with the radio host! My biggest headache is why to be polite in English. It's much easier to just say "Open the window!", but in English that can sound really terribly. I have to think about who I'm talking

to and then decide whether to say it, "Open the window, please!" or "Could you open the window, please?" or even a long one "Would you mind open the window, please?"
