本研究运用会话分析研究方法，以自然发生的汉语日常互动为语料，分析抱怨第三方行为的“合理化”回应模式。语料分析识别出“合理化”回应的三种方式：取消被抱怨行为的故意性、普遍化被抱怨行为、凸显被抱怨行为的光明面；通过合理化回应，抱怨的受话人重新诠释抱怨者建构的被抱怨行为，转变抱怨者对被抱怨行为的理解，帮助抱怨者走出消极状态。“合理化”回应属于立场不一致回应，却在一定程度上有助于维系社会和谐。

Using conversation analysis as its methodology and taking natural mundane interaction in Mandarin as its data, this study examines “justifying” the complainable as a response to third-party complaining. Three practices of justifying are identified out of data analyses, including canceling the deliberateness of the complainable, generalizing the complainable, and highlighting the bright side of the complainable. The complaint recipient’s reinterpreting the complainable through justification changes the complainer’s perception of the complainable, and helps the complainer step out of a negative state. Despite being a disaffiliative response, justifying the complainable to some extent contributes to maintaining the social solidarity among the participants.
