本文运用修辞结构理论分析了忠实于原文的译文,发现这些译文的译者对结构段的划分以及对结构段之间的逻辑关系的理解是正确的,也分析了错误的译文,发现误译常常是对原文结构段之间的语义关系误解所致。这样,本文从正反两个方面论证了修辞结构理论中的结构段可作为翻译单位。 This thesis uses the rhetorical structure theory to analyze the translation which is faithful to the original text. It is found that the translators of these translations are correct in understanding the division of structure sections and the logical relationship between the structure sections, and also analyze the wrong translations. It is caused by the misunderstanding of the semantic relations between the textual structure segments. In this way, the dissertation proves that the structural segments in the rhetoric structure theory can serve as the unit of translation from two aspects.
