人们的言语交际状况无疑是十分复杂的,但是都遵循着一些准则。最重要的是合作准则,即在谈话中为了先确定一个参与者都能够接受的方向,删除不适合谈话目的或方向的话语,这要求人们参与交谈时要使你说的话符合所参与的交谈的公认目的或方向。人们有的时候遵循合作原则,以直截了当的形式说话,有的时候却不遵循甚至故意违反合作原则,这就是人们在会话当中的“得体原则”。合作原则与得体原则互相补充,它们分别适合不同的语言交际环境,保证了人们日常交流的顺利进行。得体原则有三个准则:礼貌准则、幽默准则、克制准则。本文即以电影《让子弹飞》为例,分析克制准则在电影对白当中的应用。 People’s communicative situations are undoubtedly very complicated, but all follow some guidelines. The most important is the principle of cooperation, that is, in the conversation, in order to determine the direction that one participant can accept, to delete the utterance that is not suitable for the purpose or direction of the conversation, which requires that people should participate in the conversation in line with the conversation Recognized as a goal or direction. Sometimes people follow the principle of cooperation, speak in a straightforward manner, sometimes fail to follow or even violate the principle of cooperation. This is the “proper principle” of people in conversation. Cooperative principle and decent principle complement each other, they are suitable for different language communication environment, to ensure the smooth progress of people’s daily communication. There are three principles of decency: politeness, humor, restraint. This article is based on the movie “Let the Bullets Fly” as an example to analyze the application of restraint in film dialogue.
