This thesis, based on the author＇s back translation training exercise, intends to make a constrastive study of source text in English and its back-translation precisely from the aspects of word choice, collocation, and sentence mechanics. Results have shown that by doing back-translation practice, the learners will strengthen their awareness of language differences between English and Chinese. Besides, as a special kind of translation, back-translation has its implications on English learning and Chinese-English translation, such as being a recitation method and testing tool.展开更多
