from what i learnt . you only fail when you stop trying .

when do you knew that you begin to improve the language which you learn ?? I knew that there are a lot of signs show you to what extent you improve in learning language but i think one of the most important sign is that when you begin to think in language you learn while speaking without trying to think in it in your native language then try to translate it to the language you learn ...in other words if you begin spontaneously to express what you want to say without thinking in it in your native language and think directly in language you learn I can say that you are really on right way .

From your point of view what are the main problems that face non Native speaker ??? I would like to talk about the main problem I face , Often I will write down a sentence thinking it means exactly what I want to say, but then find out that the words don’t actually mean what I think . My thoughts will be fluid and coherent when I conceive of them in my native Arabic. But I suddenly feel as if their logic is lost once translated into English. It is hard to convey original thought, because so much effort must first be put into learning how to translate every idea. Finally, if you are not a native speaker, you cannot always express your thoughts as you wish to. How difficult it must be to reach a “eureka” moment but feel that the words are inadequate to describe it; what a challenge it is to articulate ideas in a language not your own :)))

How English became the Language of Science in spite only 5 percent of people worldwide are native E? 1_More than three-quarters of scientific papers today are published in English—and in some fields it is more than 90 percent. 2_By the 1990s, US produced more than 30,000 new science Ph.D.s a year. More than a million new American researchers in the 20th century, almost all writing and publishing in English, have helped to make it the undisputable lingua franca. 3_ if you are not a native speaker, you cannot always express your thoughts as you wish to. How difficult it must be to reach a “eureka” moment but feel that the words are inadequate to describe it; what a challenge it is to articulate ideas in a language not your own. and that will increase the scientific production in English language ..

what is your opinion ? sometimes you can not explain why things are the way they are in your native language ? i think that learning language itself need sense not only superficial learning try to translate word by word from your native language to the language you wanna learn , instead of that you must understand what behind the talk then try to express the meaning .. besides you should understand how native speakers community think ,you should recognize on their culture ,finally if you immerse yourself in community like their community and become a member of their society, you can learn their language easily ,
