摘　　要：题元角色的句法实现作为"句法-语义"接口的重要环节,直接关系到句法结构的生成。本文基于语义知识库,以施事和受事两个题元角色为典型个案,考察了基本题元角色的句法实现及其语义制约问题,分析了词汇单位、基本题元角色以及句法成分三者之间的关系。一方面,揭示了基本题元角色句法实现的常规和非常规句位以及同一句位对不同题元角色类型的优选序列;另一方面,揭示了同一基本题元角色句法实现时的语义制约特点以及同一句位对不同义类词语充任角色的选择序列差异。As an important segment of the "syntax-semantics" interface, the syntactic realization of the thematic roles is directly related to the generation of the syntactic structure. Based on the semantic knowledge base,taking agent and patient as typical examples,this paper examines the syntactic realization of basic thematic roles and their semantic constraints. Meanwhile,the relationships among lexical categories,basic thematic roles and syntactic components are investigated. The results show the conventional and unconventional positions in the syntactic realization of the basic thematic roles and the optimal sequence of different role categories in the same sentence position.Moreover,it reveals the semantic constraint features of the same basic roles in syntactic realization and the priority sequence difference in the same sentence position selecting words in different categories as roles.
