It's difficult to master any one language I am improving my English. but in my eyes, it's so difficult to master any one language. Actually, it takes me a few years to study it. when I entered to the high school I had to study it as a subject. For a high score in the exams, I just tried to add my vocabulary by repetition, learn English grammar and do too much exercise, so that until now,I cannot apply English to contact with other foreigners. I graduated with BE, and engaged in thechnical support in one of Germany Corp. it's so urgent to master English. so I found the forum of learnig language resourse on tne internet.
