>I wish to my problem about accent. But I'm not sure. My problem about practice. I can fair read and difficulty write but I can't speak. I can undestand a lot of things when I watch TV but when I speak... :(

That seems to be quite common with learning a foreign language. When I was stationed in Germany I knew several American soldiers who could understand German reasonably well but who could hardly speak at all. I also knew serveral Germans who understood English but couldn't speak it.

I seem to be the only person I know who has the reverse problem. I can read French well enough to follow a newspaper or magazine, but probably not a book. I can speak it well enough to be understood (once you get past my New York City accent). But I can only understand the language when I hear it spoken with an American accent.
