科普短视频中的互动元话语研究

A Research on Interactional Metadiscourse in Science Short Videos

摘要: 科普短视频是一种正在快速发展的新兴科普形式。相关研究多集中在创作、传播、翻译等角度。其中有不少学者关注到科普短视频作者与观众紧密的互动关系，但有关内容缺乏语言学角度的解读和支撑。因此本文聚焦科普短视频中的互动元话语，对作者使用语言资源与观众互动的情况进行深入探讨。互动元话语是作者评价和介入命题信息的手段，包含立场特征和介入特征两个范畴，其中又包括模糊语、增强语、态度标记、自我提及、读者指示词、指令语和疑问句7个子类别。经过统计分析，本文揭示了互动元话语在科普短视频中的重要作用。合理使用互动元话语可以帮助作者与观众建立亲近、友好的互动关系，同时展现出客观、严谨的科学态度。

Abstract: Short video is a newly developed way of popularizing science. Relevant studies mainly focus on creation, communication and translation of science short videos. Among these studies, many scholars have noticed the frequent interaction between the author and the audience, but there remains a lack of evidence in the perspective of linguistics. Therefore, this paper focuses on the interactional metadiscourse in science short videos, trying to investigate the author’s use of lan-guage resources to interact with the audience. Interactional metadiscourse is a means for the author to evaluate and intervene in propositional information. It includes two categories: stance features and engagement features. The two categories can be further divided into seven subcategories: hedges, boosters, attitude markers, self-mentions, reader pronouns, directives and questions. Through statistical analysis, this paper reveals the significance of interactional metadiscourse in science short videos. It helps the author establish a close and friendly relationship with the audience, at the same time showing the rigor and objectivity of science.
