英语怎样学才能做到一劳永逸？

Why we still need grammar？

The first reason is that grammardoes have a role in language teaching. It is not something that we are completely unconscious. 

The second reason why we need grammar is when we are learning a language as grown-up. It’s that grammar gives us a short cut to learning. It’s a quick way to understanding something.

The third reason why we learn grammar is that it’s expected. In other words it is unimaginable that we would do a language and no thave any grammar. If we don’t have any grammar, all the mistakes we make will become a habit. And we will learn to form very very bad habits in the way we express ourselves, because no one could correct that.”

那么有人要问了，快速是多长时间？约30小时。有的人认为我可能在吹牛皮，其实能做到这一点的又不只是我一位老师，也没有什么好吹嘘的。系统学语法以后才真正知道应该怎么学英语。
