Taking the theory of multimodal analysis as the theoretical basis and 7 ppts in an MA thesis defense as the research data, this paper uses a combination of qualitative and quantitative methods to analyze the distribution and realizations of types and modalities of PPTs in this MA thesis defense. The results show that the analyzing type accounts for the highest proportion to make sure the PPT defense presentation is academic and serious. The use of connecting, persuading, and prompting types has a strong personal tendency, varying from person to person. The visualizing type takes up the lowest proportion among them, indicating that pictures are the last modality that demonstrators tend to use. The paper further explores how meanings of MA thesis defense are constructed multimodally, and investigates the characteristics of PPT as a thesis defense genre, aiming to give some suggestions and instruction on ppt presentation for thesis defenses.
