I read a book (books), magazines, website (and websites), for example news in level (news at my level of English knowledge)..., watch videos in (on) youtube (YouTube) or some movie (movies). Do you have any suggestion (suggestions)?
You use a good variety of material, Jarka! It sounds like you choose something to study each day. Watching videos and movies with subtitles can be an enjoyable way to learn a little vocabulary and keep you motivated. Do you do any writing on sites like Lang-8 com, and do you have any simple conversations with native speakers of English? I also agree with a previous comment about singing to songs you like (and asking native speakers if you have questions about the vocabulary) because you can practice pronunciation and intonation. I would be glad to help you as you practice English.
