S.O.S

I teach English language. I understand every word when I read books and hear phrases in English, I understand when I hear English phrases, but I speak and write very badly (you may have noticed), please give me some advice.

Practice, practice, pratice :)

To get better at speaking - have conversations with native speakers and transcribe tv shows, talk radio etc.

To get better at writing in English - translate newspapers, and review grammar when you have time.
