由格赖斯所提出的会话含义理论是语用学的核心内容,其产生于交际双方不严格地遵守合作原则及其相关准则。而这种对规则的违反源于会话语境的变化。因此,准确把握语境在确定会话含义过程中的作用机制很有必要。通过把语句的会话含义放在语境谓词下进行考察,可以发现语境对会话含义的确定性的作用机制有三种情况。 The theory of conversational implicature proposed by Grice is the core content of pragmatics. It stems from the fact that both parties of communication do not strictly abide by the principle of cooperation and its related norms. And this violation of the rules stems from changes in the conversational context. Therefore, it is necessary to accurately understand the mechanism of context in determining the meaning of conversation. By examining the meaning of the conversational sentences under the contextual predicate, one can find that there are three mechanisms by which context can determine the meaning of the conversational meanings.
