在信息化时代的背景下,翻译量迅速增加,要求翻译的准确性及时效性,传统的纯人工翻译已不能满足日益增长的需求。计算机辅助翻译(CAT)使译员免于翻译重复信息,从而提高工作效率。本文以作者亲身使用Trados完成翻译任务为例,论述了CAT是翻译界的一场技术革命。同时,也分析了Trados的一些不足。 Under the background of information age, the quantity of translation increases rapidly, the accuracy and timeliness of translation are demanded. The traditional purely manual translation can no longer meet the increasing demand. Computer-assisted translation (CAT) frees translators from translating repetitive information to increase productivity. In this paper, the author uses Trados to complete the task of translating himself as an example, and discusses that CAT is a technological revolution in the field of translation. At the same time, it also analyzes some problems of Trados.
