习近平总书记强调要在话语体系方面体现中国特色、中国风格、中国气派,进而坚定文化自信。本文梳理了当前高校外语教学文化自信存在问题,通过语言学理论对文化自信的理论内涵及必要性进行了分析。指出语言作为文化的直接载体,具有显著的文化属性。外语学习者易对目的语文化形成被动认同,对本土文化产生被动排斥,为此本文从教学实践角度给出了应对路径。 General Secretary Xi Jinping emphasized the need to embody Chinese characteristics, Chinese style and Chinese style in the discourse system so as to further strengthen cultural confidence. This paper sorts out the existing problems of cultural self-confidence in foreign language teaching in colleges and universities and analyzes the theoretical connotation and necessity of cultural self-confidence through linguistic theories. It points out that language, as a direct carrier of culture, has significant cultural attributes. Foreign language learners tend to form passive recognition of the target language culture and produce passive rejection of the local culture. Therefore, this paper gives the response path from the perspective of teaching practice.
