本文在最简方案（Ｃｈｏｍｓｋｙ，１９９３；１９９５）的框架内探讨了英语中间结构的句法机 制。我们认为，英语中间动词的逻辑主语在句法层次上存在并且具有句法作用， 是一个主目语（ａｒｇｕｍｅｎｔ）位置上的ＰＲＯ。英语中间结构的生成牵涉到ｗｈ－ ｍｏｖｅｍｅｎｔ。中间结构的表面主语在一个非题元（ｎｏｎ－ｔｈｅｍａｔｉｃ）位置上原位生成 （ｂａｓｅ－ｇｅｎｅｒａｔｅｄ）。在中间动词的宾语位置存在一个带格的题元空元素（ｃａｓｅ－ｍａｒｋｅｄ ｔｈｅｍａｔｉｃ ｅｍｐｔｙ ｅｌｅｍｅｎｔ），它通过Ｗｈ－ｍｏｖｅｍｅｎｔ移到［Ｓｐｅｃ，ＣＰ］位置，充当一个空 算子（ｅｍｐｔｙ ｏｐｅｒａｔｏｒ），约束着留在宾语位置上的ｗｈ－ｔｒａｃｅ。在逻辑形式层次，同标 的表面主语和空算子构成一条组合链，使得非题元表面主语可以合法存在，并使 空算子－变量链具有了所指。这种分析维持了诸如投射原则和题元准则等基本原 则，并且使英语中间结构的特性得到了合理解释。
This paper explores the syntactic mechanism of English intermediate structure in the framework of the Minimalist Program (Chomsky, 1993; 1995). We think that the logical subject of the English intermediate verb exists at the syntactic level and has a syntactic function. It is a PRO at the position of the argument. The generation of English intermediate structures involves wh-movement. The surface subject of the intermediate structure is base-generated in a non-thematic position. There is a case-marked thematic empty element at the object position of the intermediate verb, which moves to [Spec, CP] through Wh-movement and acts as an empty operator, constraining Wh-trace left on the object. At the logical level, the co-ordinate surface subject and the null operator form a combined chain, so that the non-title surface subject can exist legally and the null operator-variable chain has the meaning. This analysis maintains such basic principles as projec- tion principle and title principle, and gives a reasonable explanation of the characteristics of the English intermediate structure.
