翻译是用一种语言形式把另一种语言形式里的内容重新表现出来的语言实践活动,而翻译单位的选择亦是许多翻译学者经常讨论的问题。本文以彼特·纽马克的语义翻译与交际翻译理论为依据,提出以此来选择翻译单位的新方法,即语义翻译所选择的翻译单位应该尽量小一些,交际翻译的翻译单位应尽量大一些,而不应当具体加以规定限制。 Translation is a linguistic practice that recreates the content of another language form in one form of language, and the choice of translation unit is also a topic that many translation scholars often discuss. Based on Peter Newmark’s theory of semantic translation and communicative translation, this paper proposes a new method to select translation units, that is, the unit of translation selected by semantic translation should be as small as possible and the unit of translation of communicative translation should be as large as possible , But should not be subject to specific restrictions.
