摘　　要："语段表征理论(SDRT)"主张依赖语篇关系来构建具有层级性的"语段表征结构"。语段表征结构独特的构建过程以及用于回指确认的两个语篇约束规则,解决了其他理论所无法解决的问题,特别是能有效地解决句子、句群为先行语的回指问题。然而,SDRT也存在其不足之处,如,语篇关系的分类标准和话题的统领作用不明确导致了实际应用中的缺陷。Segmented Discourse Representation Theory is postulated to handle the full range of abstract entity anaphoric phenomena. Discourse relations play a leading role in the construction of the hierarchical Segmented Discourse Representation Structures. Moreover, two discourse constraints-Availability and Well-foundedness--are formulated to deal with anaphora resolution. SDRT can solve many anaphoric problems which other theories have failed to do. However, no theory is perfect and SDRT is no exception. SDRT involves too many discourse relations, which seems unnecessary and redundant. And Asher establishes no clear criterion for the categorization of discourse relation. In addition, he shows his hesitation about the topic-dominating role. Moreover, the discourse constraints fail to guide the reader to identify the correct referent.
