英语同位语从句结构的递归模式

Recursive modes of appositive clause structures in English

本文探讨复杂英语同位语从句结构的构建方式以及这些方式的异同。通过对学术英语著作《语法化》(Hopper&Traugott 2001)一书的统计和分析,本文发现复杂的英语同位语从句结构是通过边际成分递归和核心成分递归两种方式生成的,两者的重写规则不同。边际成分递归的多次运用即多层递归可生成多层递归结构。核心成分递归的生成能力比多层递归的生成能力更强,但是两者也呈现出一定的共性,即具有右向迭代性质,从而使递归运算更加容易。

This paper explores the ways in which complex appositive clause structures in English are constructed and the differences and commonalities between these ways.Through counting and analyzing the appositive clauses in an academic English book Grammaticalizaiton(Hopper&Traugott 2001),we find that complex appositive clause structures are generated by two recursive modes-marginal component recursion and core component recursion,whose rewriting rules are different.The multiple applications of marginal component recursion,namely multiple recursions,can generate multiply recursive structures.Core component recursions are more generative than multiple recursions.However,they show some commonalities;that is,they both have the property of rightward iteration,thus making recursive computation easier.
