Well. Hello first, finally I've logged in EnglishClub.com (I've got some problems for log at the first time). I'm from Brazil. But, never mind. My problem here it's about my tongue. Even in my native language I've these problem: some words I can't say correctly on a full sentence. Let's take the word "girlfriend". When I say it go correctly, even in normal speed. But when I say it in fast speed, go "Guuffriend" (and sometimes Gurlfiend), and there's a lot of words that I can't say correctly. As I've the same problems in Portuguese (my native language), and here everyone understand me, do you think that the americans will understand me even with this problem? It isn't even happen with all the words, often with "r" words, "l" words, and anothers.
Just to tell: I read fairly well these words, all the sounds of English I do perfectly well. Ok, I need someone help for I keep my pronounciation well. Thank for everyone that read these text.
