“A倒是A”小句属于同义反复式“A是A”的一种,其否定形式为“A倒是不/没A”。本文首先从句内语境和句外语境两个方面来分析小句“A倒是A”的语义结构特征,其次分析了“A倒是A”与“A倒不/没A”谓词选择的不对称性,最后从认知语用的角度,运用关联理论对小句所表达的会话含义进行推导,认为其会话含义是可推导的,其语境效果是通过新旧信息相互作用来表现的。 “A is the A ” clause is synonymous with repeated “A is A ”, the negative form of “A is not / no A ”. In this paper, we first analyze the semantic structure of the sentence “A is A ” from the context of the sentence and the context of the sentence outside the sentence, and secondly analyze the “A” and “A” In the end, from the perspective of cognition and pragmatics, we use the theory of relevance to deduce the meaning of conversations expressed by clauses, and think the meaning of conversations is derivable. The contextual effect of the predicate is through the interaction of old and new information To show.
