英汉语都存在一些只能用于否定结构,受到否定环境限制的表达式,被称为否定极项。否定极限在英汉两种语言中虽然属于不同的语法范畴,但都有一定的共性。本文从语义的角度通过对比分析英汉语一些典型的动词性、副词性及限定性否定极项,发现英汉语否定极项都有着极性语义,都必须依赖否定算子而存在,且相较而言,汉语的否定极项较复杂。 There are some expressions in English and Chinese that can only be used for negative structures and are limited by the negative environment. They are called negation items. Negative limits in English and Chinese although the two languages ​​belong to different grammar categories, but have some commonalities. This paper, from the perspective of semantics, analyzes some typical verbal, adverbial and restrictive negation terms in English and Chinese and finds that both negation and negation in English and Chinese have polar semantics, and both must rely on negation operator, Words, the negation of Chinese extremely complex.
