摘要
本文以辐射范畴理论为基点,探讨假言推理中前、后件关系、推理展开方式以及逻辑规约度等要素,认为IF条件句用法的变异类型相互有本质联系,派生主要产生在主从句间关系、对从句真值的假设、句中突显内容的性质这3个认知层面上,原型用法在这3个维度上按一定的规则、以不同的逻辑推理方式、沿不同方向派生出各类变体用法,构成整个IF条件句的辐射范畴。
Based on radial category theory, this paper explores the essential connections among the varieties of IF-conditionals and argues that variations of IF-conditionals could be explicated via three cognitive dimensions, namely relations between the main clause and the subordinate clause, reliance on the subordinate clause＇s truth value during the inferential process, and assignment of salience on the conditionals. The conclusion is that variations of IF-conditionals are derived from prototypical cases and then deviate from proto-typicality through these different cognitive dimensions in accordance with certain rules and habits along different lines.
