Aspects of Sentence Structure Extension by Functional Categories and Adjuncts from the Perspective of the Syntax-Semantics Interface

本研究的目的是从句法-语义界面的角度考察功能范畴和附加语是如何参与由谓词及其论元构成的核心命题句法宾语发展成更大的句法宾语的过程。研究的主要发现有以下三点。(1)功能范畴根据句首固有的句法和/或语义属性扩展句子结构，语义解释与句法推导并行进行，如Kaneko(2006)和Kaneko(2007a)特别提到对各种从句的时间解释所证明的那样。(2)Kaneko(2008a)证明了附加词可以与最大投影词和中间投影词合并，并且这两种附加词都可以被分析为合并目标“最大”投射的实例，因为在Chomsky(1995)的空短语结构理论下，投射是以关系和派生的方式定义的，它们总是“最大”的，是合并操作的目标。(3)金子(2006)和金子(2008b)证明了方位和构形因素参与了连接附加语及其修饰的过程(尤其是功能中心语)。此外，金子(2007b)指出了当前教育语法在处理功能范畴所许可的嵌入句法扩展和省略现象方面存在的一些问题，并认为我们需要在教育语法中引入成分的概念，X理论的基本见解，语法关系和范畴之间的区别等。

The purpose of this research project is to investigate how functional categories and adjuncts participate in the processes in which nuclear propositional syntactic objects consisting of predicates and their arguments develop into larger syntactic objects, from the perspective of the syntax-semantics interface. The main findings of the research are the following three points. (1) Functional categories extend sentence structures in accordance with the inherent syntactic and/or semantic properties of their heads, and semantic interpretation is carried out in parallel with syntactic derivation, as demonstrated in Kaneko (2006) and Kaneko (2007a) with special reference to temporal interpretation of a variety of clauses. (2) Kaneko (2008a) shows that adjuncts can be adjoined to maximal and intermediate projections in terms of Merge, and both types of adjunction can be analyzed as instances of Merge targeting "maximal" projections, because under the theory of Bare Phrase Structure of Chomsky (1995), projections are defined relationally and derivationally and they are always "maximal" as targets of the operation Merge. (3) Kaneko (2006) and Kaneko (2008b) demonstrate that locality and configuration factors are involved in the process of connecting adjuncts and what they modify (especially, functional heads).Furthermore, Kaneko (2007b) points out a number of problems with current educational grammar in the treatment of syntactic expansion by embedding and ellipsis phenomena licensed by functional categories, and argues that we need introduce to educational grammar the concept of constituency, the basic insights of the X'-Theory, the distinction between grammatical relations and categories, and so on.
