This paper, based on Multimodal Discourse Analysis and Systemic Functional Linguistic, adopts case study analysis of the teachers’ non-verbal behaviours and visual modes in PPT courseware, aiming to explore how various modes cooperate to facilitate teacher-students interaction and realize three metafunctions in class. The author expects this study will be of help in elevating the teacher’s awareness of non-verbal behaviours in teaching to optimize the teaching and learning effect in class.
