prototype theory and categorization

Meanwhile the prototype theory itself also has insurmountable limits: problems of categorization based on similarity, variability of prototypes and neglect of the closely defined concepts.

同时原型范畴理论自身也存在难以克服的局限：基于相似性的范畴化问题、范畴原型的可变性以及忽视了定义严密的概念范畴。

Grasping the progress and limitations of prototype theory can theoretically deepen our understanding of language categorization.

把握原型范畴理论的进步与局限能在理论上深化我们对语言范畴化的认识。

Next the author mainly interprets category, categorization, prototype category theory and their implications for vocabulary teaching.

然后本文详细介绍了一个在大学英语课堂中实施以原型范畴理论为指导的词汇教学的实验。
