任何语言都有歧义现象,英语也不例外。本文将主要从交际效应的角度出发,把交际过程中出现的歧义现象分为蓄意歧义(intentional ambiguity)和无意歧义(unintentionalambiguity),并分别结合教学实践加以分析举例。这样的分类,能显示语言创造性的积极的一面,和因节约性而引发的消极的一面,在教学中区别对待,无疑会得到事半功倍的效果。 Any language is ambiguous, English is no exception. This article will mainly divide the phenomenon of ambiguity appearing in the process of communication into intentional ambiguity and unintentional ambiguity from the perspective of communicative effect, and give an example with the analysis of teaching practice respectively. Such classification can show the positive side of language creativity and the negative side triggered by economy. It will undoubtedly achieve more and more effective results in teaching.
