本文从认知语言学的角度,对范畴化理论的等级结构及其过程进行了粗浅探讨。范畴化是人与客观世界相互作用对事物进行分类的高级认知活动。范畴化有三个层次,即基本范畴,上位范畴和下属范畴。原型范畴在基本层次范畴得到最好体现。范畴化是一个完整的动态过程,经历了无范畴,范畴化,非范畴化和重新范畴化四个阶段。 This article from the perspective of cognitive linguistics, the hierarchical structure of Categorization Theory and its process were discussed. Categorization is the high-level cognitive activity that people interact with the objective world to classify things. Categorization has three levels, that is, basic categories, superordinate categories and subordinate categories. The prototype category is best represented at the basic level. Categorization is a complete dynamic process that has undergone four stages of uncategorization, categorization, de-categorization and reclassification.
