Language is actually a congnitive process of the brain

I'm a native Chinese speaker and I have learned English for 30 years. English and Chinese are the channels I can see and hear from the world. The world is quite interesting also a bit lousy. However, that is the reason why the worls is wonderful, because we can alway observe the grace from each affair in our lives.

Since I'm an ESL (English as a second language), English grammar / logic is one of the key ability I need to obtain.

Logic? Yes! Language is a logic system rather then simple memorizing.
Believe it or not? Come to talk to me and I'm sure you will be convinced that language is actually a congnitive process of the brain.
