摘  要:英语中大多数第三人称代词和先行语出现在同一语句或相邻语句,但是有些代词则需向前追溯两个语句甚至更远距离,才能找到对应的先行语。为确保在回指解析的过程中,所有潜在的先行语都被纳入解析范围,本研究将修辞结构理论引入代词可及性的讨论,基于修辞结构分析提出了两个不同层面的结构分析单位,并以此为基础对英文书面语篇中的第三人称代词先行语的搜寻范围进行更为合理的界定。此搜寻模式在回指解析中的有效性通过一定数量的英文语料得到充分验证,尤其对远距离回指的解析效果十分理想。Most third person pronouns can find their antecedents in the same sentence or in the preceding one. However, in the case of long-distance anaphora, we need to trace back two or more than two sentences to find the proper antecedent. In order to make sure that all potential antecedents are taken into account for anaphora resolution, Rhetorical Structure Theory is brought into the discussion of referential accessibility in this article. Op- erating at different levels, two analytical units are proposed in the light of rhetorical structure analysis and they pave the way for a more effective searching scope of candidate antecedents for the resolution of third person pronouns in English texts. The effectiveness of such a searching model in anaphora resolution is fully validated with a number of English texts. In particular, its performance in the resolution of long-distance anaphora is rather promising.
