外置変形は必要か

Abstract

Since Rosenbaum (1967) who established the status of Extraposition Transformation, many arguments have come about regarding this transformation. Among others, the following three problems appear to be very popular : (i) Ordering problem between Extraposition and other transformations. (ii) Where is an extraposed sentence or phrase attached? (iii) Is Extraposition Transformation necessary? With respect to the first problem, this seems to be out of the question at the present time because of the free ordering of transformational rules based on the Trace Theory. But many scholars (for instance, Williams (1974), Reinhart (1980)) still are arguing about the second problem. Furthermore, recently, the third problem which is concerned with the existence of Extraposition Transformation itself is going to draw the attention of the people to Koster (1978) and Rochemont (1978). We do not have enough space to treat both (ii) and (iii), so we will focus on the third problem because the problem of the existence of Extraposition Transformation seems to be more important than that of the position where an extraposed sentence or phrase must be attached.
