名前形容词和其所修辞的名词间有多种语义关系,有的关系可以用连言(conjunction)解析,有的不可以。本文在前人研究的基础上探讨集合理论下这两者之间的关系,试图解释为什么大多数的形容词既可以放在名词前作定语,又可以在该名词放在名前作主语的条件下,置于句末充当谓语,而有些名词或者名词却只能担当谓语,或者说在充当谓语时,语义发生了变化。本文还将试据此尝试对汉语中名前修饰语的重新分野,以建构符合汉语实际的名前修饰语的语义系统。 There are many kinds of semantic relations between famous adjectives and their rhetoric nouns. Some relations can be analyzed by conjunction, and some can not. Based on the previous studies, this paper explores the relationship between the two under the theory of set-ups and attempts to explain why most of the adjectives can be attributives both before the noun and under the condition that the noun is put on the preposition as the subject At the end of the sentence acts as a predicate, but some nouns or nouns can only play the predicate, or that when acting as a predicate, semantics have changed. This article will also attempt to re-divide the pre-existential modifiers in Chinese so as to construct a semantic system that conforms to the actual Chinese pre-existential modifiers.
