汉语和英语的差异可以体现在语言的多个方面,如词形和词义的差异。本文从认知语言学的角度来探寻英汉词汇的差异。词汇是意义的载体,而范畴是对词汇意义概念进行微观剖析的最好工具。本文用范畴的机制对英汉语中的旧词和新词进行研究,以揭示其背后的文化差异,解决语言使用中的概念缺失问题,提高跨文化交际效率。 The differences between Chinese and English can be manifested in many aspects of language, such as the difference between word form and word meaning. This article explores the differences between English and Chinese vocabulary from the perspective of cognitive linguistics. Vocabulary is the carrier of meaning, and category is the best tool for microscopically analyzing the concept of lexical meaning. In this dissertation, we study the old words and new words in English and Chinese with the help of category mechanism to reveal the cultural differences behind them, to solve the problem of missing concepts in language use and to improve the efficiency of intercultural communication.
