随着多媒体的发展,话语的多模式性日益凸显,多模态话语分析理论应运而生,逐渐成为语言学研究的热点之一。以此试以多模态话语分析理论为研究视角和理论基础,对上海世博会志愿者标志图文设计进行多模态话语的社会符号学分析,揭示文字与图像共同作为社会符号的表意功能。 With the development of multi-media, the multi-modalities of discourse become increasingly prominent. The theory of multi-modal discourse analysis has emerged as one of the hot topics in linguistics. Based on the multi-modal discourse analysis theory as the research perspective and the theoretical basis, this paper tries to analyze the socio-semiotic discourse of volunteer signage design in Shanghai World Expo, revealing that the characters and images together serve as the ideographic function of social symbols.
