翻译单位是翻译理论和实践中的一个非常重要而且是素有争论的问题。以往的研究存在着一定的误区,忽视了在具体翻译活动中“条件”的重要性。翻译单位的实质是译者心理翻译单位在语言层面上的映射,翻译单位的生成是一个动态的过程,译者的主体认知因素在其中起到最关键的作用。具体翻译过程中,译者心理翻译单位可以体现在不同的语言层次上,始终贯穿整个翻译过程的固定的翻译单位是不存在的。 Translation unit is a very important and controversial issue in the theory and practice of translation. There are some misunderstandings in past studies, ignoring the importance of “conditions” in specific translation activities. The essence of the translation unit is the mapping of the translator’s psychological translation unit on the linguistic level. The generation of the translation unit is a dynamic process, and the translator’s main body cognitive factor plays the most crucial role. In the process of concrete translation, the translator’s psychological translation unit can be embodied in different language levels, and the fixed translation unit that always runs through the entire translation process does not exist.
