Abstract:This paper employs the multi-modal critical discourse analysis method to study the interpreting process of press conferences.By integrating social function and cognitive mechanism, the two key aspects for interpreting research, it explores the construction of meaning by means of the interaction of audio and visual modes.The visual mode underpins the audio one in a way to frame the power relations of the parties involved in the interpreting setting, while the audio mode is instrumental to the retrieval of the interpreter's cognitive process and the analysis of interpreting strategies.With multimodal critical discourse analysis, the paper qualitatively examines the interpreting process and broadens the scope of empirical research on interpreting, which is of significance to both the practice of interpreting and its teaching.
