习语具有较丰富的文化内涵。英汉习语在表现语义和文化特征时，可分为三种类型：对应的，部分对应的和非对应的。翻译中，对习语所含文化因素的处理一般可分为两种方法，即主要以源语文化为归宿的异化法和主要以目的语文化为归宿的归化法。文化移植需有多种方式，在习语翻译中，归化与异化相辅相成，均有其存在的价值。 Idioms have rich cultural connotation. English and Chinese idioms in the performance of semantic and cultural characteristics, can be divided into three types: the corresponding, partly corresponding and non-corresponding. The translation of the cultural factors contained in idioms generally can be divided into two methods, namely, the main source of culture as the destination of the alienation method and the main target language culture as the home of the domestication law. Cultural transplantation requires a variety of ways. In idiom translation, naturalization and alienation complement each other and both have their own value.
