Paul Coffey: Most people learn to speak English as a first language not by studying the grammar, but just by engaging with the language in a real sense. He says his lived experience of getting to fluency in two new languages matches very closely the methods that Chris is talking about. For example, he talked about acquiring the language based on prior understanding, i.e. the comprehensible input approach. Based on my experience in China, I found that watching movies in their original English and then repeatedly watching them with the Chinese audio dubbing was very useful to me.
