grammar is important for us?

well, master writing doesn't mean you can speak fluently, even if you have good ablility of grasping how to use grammar correctly, you may not speak fluently and correctly,and vice versa.

I ain't form the West.But albeit their natural flow in their speech some also make a flow of flaws in their writing.And ironically Asian students are said to outdo the western students in many schools and colleges. For example i have a kid sister, in her nursery, who can speak fluent and good english at home.But when it comes to writing she just sucks.
