对于话语标记语这种常见的语言现象,很多学者都从不同角度进行了深入研究,但在外语教学领域,其语用石化现象却探讨得相对较少。本文尝试探讨话语标记语的石化成因,以其为二语教学提供一些有益的教学启示,采取积极的措施有效地防止和减少石化现象。 For discourse markers, a common linguistic phenomenon, many scholars have conducted in-depth studies from different perspectives. However, in the field of foreign language teaching, the phenomenon of pragmatic fossilization has been relatively less discussed. This paper attempts to explore the petrochemical causes of discourse markers, and provides some useful teaching inspiration for second language teaching, and takes active measures to effectively prevent and reduce petrochemical phenomena.
