Language is the carrier of culture and it conveys culture,so the language teaching should contain culture teaching. In EFL teaching,teachers should not only teach the necessary English knowledge like the grammar,sentences paraphrasing and structure analysis but also consciously introduce the related cultural information like the cultural back-ground knowledge,so that students can strengthen the language learning in their culture learning. This thesis mainly attempts to analyze the disadvantage of memory-based approach to learning English,the cultural reason for Chinese students’ tendency to rely on the teachers and some common pragmatic errors made by the Chinese students in their oral communication in English duo to their lack of IC knowledge.
