话语分析是被同一个语言交际圈中的成员所使用的语言检查手段。对外语老师来说,话语分析不仅仅是调查他们自己教学实践的研究方法,而且也是研究语言学习者之间交互作用的一种工具。本文讨论了话语分析和第二语言教学之间的相互关系,并指出语言学习者如何使用话语分析探究语言是什么的问题,以及如何应用话语分析在不同的语境中达成交际目的。本文还讨论了如何利用话语分析创建更准确的第二语言学习环境,从而鼓励学习者更有效地利用第二语言达到交际目的。 Discourse analysis is the language used by members of the same language communication circle. For foreign language teachers, discourse analysis is not only a way of investigating their own teaching practices, but also a tool to study the interaction between language learners. This paper discusses the relationship between discourse analysis and second language teaching and points out how language learners use discourse analysis to explore what language is and how to apply discourse analysis to achieve communicative goals in different contexts. This article also discusses how to use discourse analysis to create a more accurate second language learning environment, thereby encouraging learners to use their second language more effectively to achieve their communicative goals.
