【摘要】 题元重合是一种独特的词汇语义、句法语义乃至认知语义现象,它为语言语义研究提供了颇具新意的分析视角、分析层面和分析手段。本文首先从内涵界定、特征描写、实质分析以及概念关联等几个方面对题元重合现象展开讨论,进而基于题元与动词语义及句子结构的密切联系,以整体事件语义中的题元为描写单位和对象,从动词情景事件和动词句式两方面着手,对题元重合的语义功能表现做进一步探讨,以观照其在事件范畴语义、句式语义中的特殊地位和运用价值,借此深化题元理论和词汇句法理论研究,从题元角色解读和功能语义分析维度对动词语义问题做出新的阐释。相关研究有助于加深对题元理论和语义角色理论本身的认识,同时对于动词事件语义、句子语义分析以及动词精细化语义描写也大有裨益。更多还原

【Abstract】 Actant?s polyrole is a unique phenomenon of lexical semantics. Syntactic semantics and cognitive semantics. It provides a new analytical perspective, analytical level and analytical tools for linguistic semantics research. This paper first discusses the phenomenon of actant?s polyrole from the aspects of concept definition, feature description, substantial analysis and concept relationships, etc.. Based on the close relationship between actant and verb semantics and sentence structure, taking the actant in the whole event semantics as describing unit and object, starting from the two aspects of verb scenario and verb sentence pattern, it explores the semantic function mechanism of actant?s polyrole, observing its special status and application value in the study of event category semantics, sentence semantics and syntax semantics, deepening the study of theta theory and lexical syntax theory, and giving a new explanation and revelation of the semantic problems of verbs from the perspective of thematic interpretation and functional semantic analysis. Related research would help deepen the understanding of the theory and thematic role theory itself, moreover, it is also helpful for the description of verb event semantics, research of sentence semantics and refined semantic description of verbs.更多还原
