dude, i dunno ur current english level, but in order to gain it, u gotta read newspapers in english, try not to read da translated subtitles frm english films, (know it might b hard at da beginnin', but remember practice make perfect). and also read books which help da most. its better to read them wif da similar level as urs, bcoz if its too easy u ain't learnin' nothin or if its too hard, u might lose interest in 'em. other thing which can practice is to communicate wif non-chinese speakers as much as possible.
things mentioned above would probably help.
good luck dude~
