How can improve my English?

Keep speaking it!
Ok, you know how babies...
they dont know a word of English and the only thing you can do is just talk to them. =]
That's the best way to learn in my eyes, just speaking it and getting more familiar with it. =D

Well, there's that, and there also is reading. Books can really help. It worked for me, I think it will work for you.

Listening to spoken English on the radio is very helpful (as long as the speakers are good!). You pick up useful phrases and just get a 'feel' for how the language works naturally.
