语义变化有五种类型:词义扩大、词义缩小、词义转移、词性变换和俗词源(查理德、罗杰斯,2000)。高职英语学生的阅读水平较差,受到语义变化的局限也较大。本文以举例的方式分析了高职英语学生的阅读水平,从语义变化的五种类型的方方面面剖析高职英语学生提升英语阅读的重要性。 There are five types of semantic changes: expansion of meaning, reduction of meaning, transfer of meaning, transformation of parts of speech and vulgar etymology (Charlie Rogers, 2000). Vocational English students have poor reading ability and are limited by semantic change. This paper analyzes the reading level of English for higher vocational students by way of example, and analyzes the importance of English for higher vocational students in English reading from all five types of semantic changes.
