汉语式话题句的结构分析

Structural Analyses of the Chinese Topic Constructions

根据传统的论元结构理论,汉语中一些话题不是动词的论元,跟述题不能通过空位或接应代词建立联系。这种话题被称之为汉语式话题。汉语式话题内部并不同质,有的可以关系化,而有的则不能,这说明它们有不同的结构来源。根据最简方案,提出前者由轻动词引进,后者由话题功能范畴引进,为Chomsky近年来关于论元结构由外部合并决定的假设提供佐证。

According to the traditional argument structure theory,some topics in Chinese are not arguments of verb,and can＇t link with their comments via gaps or resumptive pronouns and thus are called Chinese topics.Chinese topics are not homogeneous and some of them can be relativized but others can not,which shows that they have different structural origins.Based on MP,it is argued that the former is introduced by light verbs,and the latter by the functional category Top（ic）.The program can be used to support the hypothesis proposed by Chomsky that argument structure is deiermined by E（xternal） M（erger）.
