In the past,the emphasis was placed on the cultivation of language communicative competence,while the cultiva-tion of other modes was not so sufficient.Combining the multimodal interaction analysis method,the study takes the speech act of apologizing by Thai students as a case study,this paper breaks through the limitations of the previous single-language modal corpus-based approach,and describes the differences and similarities in the use of multimodal means of expression in apologizing by Thai students of different Chinese levels,as well as the differences in their multimodal interaction capabilities.The results show that Chinese as a second language(CSL)learners'multimodal interactional competence can help them fulfill their communicative intentions and improve their interactional effects,and that the introduction of the"Interactional Variation Perspective"to guiding Chinese teaching can help improve CSL learners'multimodal communicative competence.
