语用意义的理解不仅需要推理语用主体的交际意图，还需要分析语用主体生成和理解话语的理性依据。本文以《金牌调解》话语为语料，从理性的认知、工具和价值三个维度分析主持人、当事人和调解人的语言使用，从而论证了理性在语言使用中的体现。本文将这种反映在语言使用中的语用主体的理性定义为语用理性。它是语用主体语用能力的根本体现，是主体能为其语言使用提供合理性依据的能力，同时还是其语言使用所依据的规范。

The interpretation of pragmatic meaning requires the analysis of the underlying rationality of discourse production and interpretation, as well as the inference of the communicative intention of the pragmatic subject. The paper studies the discourse of the hostess, the interested parties and the mediators in the TV reality show Golden Mediation in terms of cognitive, instrumental and evaluative rationalities, and demonstrates the embodiment of rationality in language use. The rationality of the pragmatic subject as reflected in language use is termed as pragmatic rationality. The rationality is the essential index of the pragmatic subject’s competence as it denotes the capability of the subject to provide a rationale for language use, and the normative basis for language use.
