Where to find US series subtitle in ENGLISH in streaming or dowloading?(I'm not english^^)? - south park streaming english dubbed

Seeking a way to the U.S. series (The Simpsons, South Park, Prison Break, etc. ..) with English subtitles can be seen (improve my English xD). Do you know of a site, the prices of some proposed or in some music?
Thank you.
