摘要：In order to widen college English teachers’ ecological niche and promote their teaching ability, we make an empirical study on college English teachers’ teaching ability and ecological niche on the basis of Ecological Niche Theory. The paper shows how to take advantage of micro-lectures, make full use of 5C teaching strategies and form multiple teaching and learning evaluation and online teaching and learning community to improve discourse power between students and teacher, to change the role of students and teacher. In this way, college English teachers’ teaching ability will be improved greatly.
