主题性:整体回指关系体现出的一种篇章属性

根据许余龙的研究，回指释义离不开两个至关重要的因素：可及性和主题性。可及性是由回指语体现出的一种篇章属性，而主题性是先行语表达的一种篇章属性，两者似乎有着明确的分工。我们通过考察篇章回指确认的三个原则，尤其是第三个原则后发现，主题性更准确地应该表述为是由整体的回指关系体现出的一种篇章属性，尽管主题性在大多数情况下都是直接或间接地与先行语相关联。

According to Xu Yulong, there are two rather important factors in anaphom resolution, which are accessibility and topicality. Accessibility is regarded as a kind of textual attribute embodied in anaphor, while topicality in antecedent. It seems that either takes its respective functions. After exploring the Three Principles for anaphora resolution,especially the last one,it is found that topicality should well be re-formulated as a kind of textual attribute embodied in overall anaphoric relations,although in most cases topicality is associated with the antecedent dimctly or indirectly.
