How can I make my English ability better?

I've been studying English many years, but it still stays at the same level. I was wondering how I can make my English getting better. I tried to listen to community radio in English every day and read English newspapers, but it seems my improvment is limited. I realize that my spoken English is getting worse. I hope I can find a good way to improve it.

The best way to become proficient is to engage in spoken conversation as much as possible.  Reading will help you understand grammar better, but is a supplement, not a substitute.
