If the students can make full use of the fuzziness in language, their communicative competence will be greatly improved. So the fuzziness principles are advanced here to guide language teaching, which are the principle of tolerance ambiguity and the principle of active selection. And teachers should try to cultivate the students＇ cognitive learning style of inference, guessing, and association. In this way the students＇ communicative competence of using L2 will be improved.展开更多
