From the perspective of quantitative classroom observation, we select three classes of Dou Guimei teacher on behalf of the different stages of her teaching. Through the famous Flanders verbal interaction analysis, we analyze these three through the methods of observation，recording and statistics. Then we revert the mathematical conclusions we obtained to the teaching conclusions and finally discover the characteristics of Dou Guimei teacher’ teaching speech ; In order to get a more thorough research and analysis on characteristics of classroom teaching speech, in light of the lack of Flanders’ classroom teaching analysis system on speech of teachers and their students, combined with cases on classroom teaching and qualitative research methods of interviewing information, this thesis elaborate the teacher Dou Guimei’s general characteristics of the classroom teaching speech and the enlightenment it bring to us, that is the pleasure to students, the knowledge learning from it, the great importance to rhetoric, the wide application, the design of topics.
