委婉语不仅是一种修饰手段,而且是一种隐含会话含义的语言现象,是一种间接的言语行为。委婉语违背合作原则,导致会话含义的产生,恰恰是为了礼貌原则与面子论的需求。本文用语用学的“面子保全理论”阐述了委婉语在英语教学中的重要意义,并通过调查大学生面子需求的情况,提出了在商务英语教学中使用委婉语的一些策略。 Euphemism is not only a means of modification, but also a linguistic phenomenon that implies the meaning of conversation and is an indirect speech act. Euphemism violates the principle of cooperation, resulting in the generation of the meaning of conversation, precisely for the politeness principle and the need of face theory. This thesis uses pragmatics “face preservation theory” to expound the significance of euphemism in English teaching and puts forward some tactics of using euphemism in business English teaching by investigating the needs of college students’ face.
