本文探讨当一个叙述片段中插入次级片段时返回中心的解析问题。首先对话语插说进行了说明和界定,对延续和非延续过渡的中心返回及返回中心进行了形式描述。在此基础上,围绕跨层相邻语句的过渡方式,以话语体式、视角、插说话段属性为参项讨论了返回中心的解析。提出了话语插说时返回中心解析三准则:话语体式准则、视角准则和插说话段属性准则。重点分析了返回中心实现为名词语和零形式时的条件和机制。 This article explores the problem of parsing back when a sub-segment is inserted into a narrative segment. First of all, the discourse of discourse is described and defined, and the center of return and return of the continuation and non-continuance of transition is formally described. On the basis of this, the analysis of the return center is discussed based on the transitional modes of the adjacent sentences in the cross-layer, taking the discourse style, the perspective and the attributes of the insertion of the discourse as an argument. Proposed a return to the center of the discourse when the interpretation of the three criteria: discourse style guidelines, perspective criteria and insert speech segment attributes guidelines. It focuses on the conditions and mechanism for the return center to realize the nouns and zero forms.
