根据功能对等的原则,对旅游宣传中的汉英以及英汉互译进行了浅析。翻译目的论与纽马克、奈达提出的有关理论虽然侧重点不同,但核心都是功能主义。依据这一原则,译者在翻译实践中不是采取一成不变的做法,而应围绕实用性这一目的展开。基于此,对英汉互译的文本进行了分析,以论述功能对等的重要性。 According to the principle of functional equivalence, this paper analyzes the Chinese-English tourism and English-Chinese mutual translation. Although the focus of translation theory is different from that of Newmark and Nida, the core of translation is functionalism. According to this principle, the translator does not adopt an immutable practice in translation practice, but should focus on the practical purpose. Based on this, the text of English-Chinese translation is analyzed to discuss the importance of functional equivalence.
