This argument also concerns with thetopics of maintain of the ambiguity of the original text and select of the original text. The author also discussed some aspects thatpossibly or potentially affect the reversibility of the translated texts and cause the Reverse Culture Shock. Then the essay offerssome strategies in dealing with such problems in translation.展开更多
