There-be存在句的优选论分析

Analysis of English There-be Existential Sentence under the Framework of Optimality Theory

在优选论的理论框架下,从语音、句法、语用三个层面同时对英语There-be存在句的产生过程进行分析,并且对英汉两种语言的存在句进行了比较。EPP原则、主语共现原则、信息焦点原则、末尾重心原则和完全解释原则都是促使和限制英汉存在句生成的制约条件,普遍存在于两种语言之中,但它们在英汉两种语言中的等级排列顺序不同,因而导致两种语言存在句结构的不同。

This paper attempts to apply Optimality Theory to the study of English therebe existential sentence. It analyzes English there - be existential sentence from the perspectives of phonology, syntax and pragmatics, and makes a comparison between English and Chinese existential sentences. Extended Projection principle, Subjects Co - overt principle, information focus principle, end weight principle and Principle of Full Interpretation, which are the constraints of English and Chinese existential sentences, are universally existed in these two languages. The different rankings of these constraints in these two languages determine the different structure of these sentences.
