奈达的“动态对等”理论,诺德的“功能加忠诚”理论,纽马克的“交际翻译”“语义翻译”理论,都对翻译界产生过深远的影响。三人的翻译理论一脉相承,后两者都是奈达的“动态对等”理论基础上进行的开拓。本文就通过对三种理论的分析,评价三种理论的利弊,对此来指导我们的翻译工作。 Nida’s theory of “dynamic equivalence”, Nordic’s theory of “function plus loyalty” and Newmark’s “communicative translation” and “semantic translation” all have a far-reaching impact on the translation community . The three translation theories are in the same strain, both of which are pioneering on the basis of Nida’s “dynamic equivalence” theory. Through the analysis of the three theories, this article evaluates the pros and cons of the three theories to guide our translation work.
