However, there are some problems existing in practical listening teaching and textbooks： test-centered teaching and no theories and principles provided by textbooks. In fact, what we are doing in the listening teaching is to test rather than to teach, to foster passive receivers rather than active learners, to teach blindly without theoretical guidance. This article intends to analyze these problems from a theoretical perspective and puts forward some suggestions to solve the present problems.展开更多
