语言之间的交流实质上是文化之间的交流。然而,其所蕴含的文化内涵有时候会在翻译中失去。功能对等理论是在跨文化翻译中应该遵循的原则和方法。通过分析各种英汉互译的实例以及汉英典故的翻译来证明将功能对等理论应用于跨文化翻译是非常有效的,并具有积极的指导意义。 Communication between languages ​​is essentially a cultural exchange between. However, the cultural connotations it contains can sometimes be lost in translation. Functional equivalence theory is the principle and method that should be followed in cross-cultural translation.
