I whish you do not think my words in belowing are a complaint to you. To be a simple reason, I just want to practise my English with a britisher. In my experience, I’d prefer your pronunciation calss than conversation class. Perhaps I stayed a short time in your conversation calss. As did you write in your post ” the chinese students learn by passively listening” After pronunciation class, I can realise something has been learn from you. Even though, It just was a word which I spoke the wrong pronunciation before. I will pay more attention it in the future study. I know conversation class purpose is to encourage students talking freely. That is why you did not emphasis their grammar,pronunciation and sentence structure.
I agree with your point. Chinese like to think English by Chinese way. That is why there are lots of Qing English in China. we understand it .However , you did not know.
