Thanks all for the reply :
>Watch British and American movies in their original language
Yes, good idea, but most of the time actors talk very (VERY) fast...
>Rosetta Stone & Pimsleur method
Maybe interesting, I'll see...
>Come and live in the UK for a year, that should do it
Yes, of course, the best way !
But I'm talking about a mental blocking first.
Explanations : Sometimes (very rare), this blocking left my head (I feel it), and so I have a better english understanding, but the blocking come back after a few moment (I feel too)...
So my first goal is to remove this blocking, I'll progress in english after I think...
Any ideas ??
