摘要: 突发公共卫生事件并非个别的偶然现象，其社会环境影响范围不同，严重程度也各有不同。批评语言学和批评性话语分析旨在分析语言、权利和意识形态之间的关系，以及语言在社会文化演变中的作用。突发公共卫生事件的媒体话语不仅具有与传统新闻话语相同的传播效果和影响力，还具有强化性、互文性和评价性等特征。本文从批评性话语分析的视角，深入分析突发公共卫生事件的言语传播策略和话语特征，以期加深对这一新型话语的语言学理解。

Abstract: Public health emergencies are not individual accidental phenomena. They have different impacts on different social environments and different degrees of severity. Critical linguistics and critical discourse analysis aim to analyze the relationship between language, power and ideology, as well as the role of language in social and cultural evolution. The media discourse of public health emergencies not only has the same communication effect and influence as traditional news discourse, but also has the characteristics of reinforcement, intertextuality and evaluation. From the perspective of critical discourse analysis, this paper deeply analyzes the verbal communication strategies and discourse characteristics of public health emergencies, in order to deepen the linguistic understanding of this new discourse.
