I like English very much, but I've got some problems with it.
First of all, it is about pronunciation. I need to work on it more.
The other problem is that I do not have anybody I could practice my English with.I also understand that my English is poor at the moment but I try to do my best to make it better, for instance, I read English books and watch English TV channels. But I try every day, i listen to english songs and BBC radio. the second one is learning the words, i should know more words for better speaking in English. that is why I read English book: different fairy-tales, poems, rymes.
