本文基于韵律句法学理论,针对动宾、动补带宾、动宾带补三种句法结构中与轻声、轻读相关的“例外”现象,讨论轻声、轻读音节在音步组构中的韵律属性及其句法效应。 文章的主要结论是:(1)轻声、轻读音节造成了韵律上的双音节残音步,残音步为从左到右组构而成的左重式音节音步,其韵律重量相当于单音节;(2)残音步可以和另一个“音足调实”的完整音节组合形成标准音步;(3)冯胜利(2013)提出的最小词条件可以在原来以音节数量为韵律标准的基础上,增加了与音步组构相关的标准音步的三种实现方式:一是由两个音足调实的完整音节组构为标准音步;二是由一个残音步和一个音足调实的完整音节组构为标准音步;三是由一个标准音步和一个轻读音节组构为标准音步。 基于扩展后的最小词条件,动宾、动补带宾、动宾带补三种结构中与轻声、轻读相关的现象并非“例外”,仍然遵循核心重音规则。据此,汉语动宾、动补带宾、动宾带补三种结构中的所有合法现象都得到了统一的解释。
Based on the theory of Prosodic Syntax, this paper discusses prosodic properties and syntactic effects of lexical neutral tone and syntactic unstressed syllables in three types of syntactic structures—[VO], [VR O], and [VO R]. The main conclusions drawn are as follows: 1. Lexical neutral tone and syntactic unstressed syllables give rise to disyllabic incomplete feet, which are left-headed syllabic feet forming from left to right; 2. A disyllabic incomplete foot can combine with another full syllable to form a standard foot; 3. Feng’s (2013) Minimal Word Condition could expanded by considering both syllable weight and syllable number. With the extended Minimal Word Condition, the phenomena concerning lexical neutral tone and syntactic unstressed syllables in three structures are not exceptions, but adhere to Chinese NSR. Then a unified explanation is provided for all legitimate phenomena within these structures.
