原型范畴理论是基于人类认知基础的范畴化理论,这一理论的提出,揭示了人类思维的某些机制,为多义词提供了充分的理论依据。为了更好地掌握多义词,教师应重视基本范畴词的学习,重视多义词的讲解,重视隐喻的认识,从而提高学生的学习兴趣和教学质量。 Prototype theory is based on the categorization theory of human cognition. The introduction of this theory reveals some mechanisms of human thinking and provides sufficient theoretical basis for polysemous words. In order to better grasp the polysemous words, teachers should pay attention to the study of basic category words, emphasize the explanation of polysemy, and pay attention to the cognition of metaphor so as to improve students’ interest in learning and teaching quality.
