I'm sorry but your question is slightly vague. Are you trying to ask how did we learn our 'OWN' language or how do we learn 'Foreign' Language? (just kidding!) I'm learning chinese now. The way I want to learn it is by studying gradually（i.e. I really started the basics), listening to chinese songs, make a lot of chats with my chinese friends and lastly, talking to myself (not in an insane manner)... Above all, I love this language and that I find it no hard to learn it.

First of all, I am very interested in learning language. Secondly, I learn it from teachers. Thridly, I talk to people. Then, I read books, newspapers, news etc. Last, practice by myself.

basically just read books... the english language is quite complicated... although i learned this since i could speak.... i still could not perfect grammar so just try to read books, and communicate with people... "go, go, go... you can do it!!!!" :D
