Abstract:

Discourse markers in foreign language teachers' discourses as interlanguages play a decisive role in making a high quality class. The current corpus-based research Chi-square tested the frequency of discourse markers used in two parallel corpora,and contrastively analyzed the reasons in terms of the significant differences. The results show that more than half of the discourse markers used by Chinese middle school English teachers are normal-used,about one third low-used,and nearly one tenth over-used,which indicates a significant difference between Chinese and foreign teachers in terms of the flexibility,correctness and appropriateness of discourse markers. The current research provides a reference for self correction,which facilitates them in finding the deficiency in oral expression,and enlightens the professional development of English teacher.
