意合中话题化的实现——以汉语为例

Topicalization in Parataxis——Chinese as a Case in Point

本文旨在从汉英对比角度,通过结合X阶标理论来探讨话题凸显结构中话题化在实现语义和句法层面衔接时所起的照应式约束作用。我们从分析汉英短语差异入手,发现汉语的名词性短语有相对独立的题元角色,这使得汉语的主语和谓语结构间形成了有别于英语SVO结构的意念约束关系,透过句法操作中移动规则进而实现意义聚焦式功能投射。在此过程中移位造成的空语迹,由于框架的限定性作用,使述题与主位产生约束受阻效应从而实现话题化。

The study applies X-Bar Theory to probe into referential constraints enhanced by topicalization in Chinese and English respectively,when noun phrases bridge the gap between layers of semantics and syntax within the framework of topic prominence. Comparisons of Chinese and English phrasal rules indicate that Chinese noun phrases are assigned unique theta roles differentiated by relevance,which notifies different subject-predicate concordance binding relationships with regarding to Chinese SVO structures. Operations of movement rules in syntax make interfaces accessible to focus-on-meaning function projection.Empty trace leftovers caused by movements surrender to frame-setting rules,bring about theme-rheme constraints and realize topicalization accordingly.
