Pronunciation is unimportant and you DO NOT know how to teach it.

This surely should be given an award as the most illogical statement of the year. Why should he know how to teach it if it's unimportant?

The teachers who say pronunciation is unimportant in my experience have God Awful accents. It doesn't matter how many words you know or how much grammar you understand, if you can't pronounce clearly you have no business teaching English. This goes for both native and non-native English teachers.

English teacher who can't speak clearly should be tarred and brushed and thrown out of China.
