This research aims to do contribution for the application of computer-aided translation technology in the traditional translation teaching in universities. Compared with the arduous manual translation, computer-aided translation can increase translation efficiency. The application of computer-aided translation to translation teaching can improve the teaching quality and meet the massive demand of translation job market. Based on the development of CAT technology and its experiment in modern translation industry, the necessity of applying CAT technology in translation teaching is convincingly proven, which is followed by the elaboration on the design of CAT teaching modules and the construction of CAT teaching system in this research. This research investigated the application of CAT to translation teaching, including designing teaching mode, using software and hardware, managing teaching files, storing teaching resources, establishing the translation corpus and so on, which have great significances to translation teaching and translation practice. Finally, a conclusion is made that only when translation education combining with CAT Technology, can translation education meet the demand of increasing translation market, and only by applying CAT technology in translation teaching in universities, can the translation education catch up with the development of the translation industry in this information age.
