how can i find a partner fron another coutry fr practicing english?

Answer 1

Just go to chat rooms, talk to people on here, etc. There are also some pen pal agencies if you would like to try writing letters back and forth.
Just understand that most people who learn english as a second language usually have much better grammatical skills than a native-born english speaker.

Answer 2

Depends on where you are and whether you can use Skype (broadband necessary).
