Translation is a cross-lingual and cross-cultural activity proceeded from thinking and semantic levels. Though Machine Translation (MT) is able to realize the conversion between words, it does not have complicated mental cognitive ability to recognize texts. Keywords：Computer Aided Translation (CAT) ; Machine Translation (MT) ; translatorsWith the development of the Internet information technology, CAT successfully step into the translation market, and compete with the human translation. However, is CAT really better than human translation In fact, the emergence of each new tool has its necessity of existence, but t the same time it still has some limitations. In this paper, firstly I will introduce the basic concepts of CAT; secondly I will give a comparison on CAT and human translation to show the advantages and limitations of CAT;in the final, I will analysis the cause and enlightenment of those limitations.1. The basic concepts of CATIt is widely believed that " CAT is just a new way to improve the efficiency of translation. " However, it is very far from knowing CATvery well. We must know that its most notable feature is machine translation (MT). Only automatic machine translation has the greatest speed but unsatisfactory quality. In such cases, the CAT technology has been gradually valued, and it makes up for the deficiency of the machine translation. CAT is mainly composed of translation memory (TM), management system of term base, and the alignment tool.Translation Memory (TM)TM is the core of the CAT technology, it is an important part in Workbench of interpreter and translator. Its working principle is to compare the being translated section with the existing translation pieces. If the being translated segments matching with the existing fragmentsvery well, the machine will provide translations in the database for reference. For provided reference, translators can completely copy,modify to use, or abandon.(Qian Duoxiu, 2011)According to the own experiences, the author have found that the quality of TM tool is measured by the the proportion of repeated contentin the paper. On this point, is greatly limited. Only materials withlots of professional and technical words can be translated by CAT, especially to materials being constantly updated and have multiple versions. On the contrary, it is less suitable for a literary text which has complex changes in content and low rate in repeat.Term BaseTerm base is a collection of computerized terms. A term base for translation is generally a bilingual or multilingual term base. The scope of non-literary text translation is very wide, relating to manufacturing industry, financial sector, energy resources, chemical engineering, law and medicine. It is always very boring in MT, but the term bases of CAT can get lots of f terms with a quick searching speed in the course of MT. For example, Google Translator's Toolkitsr and SDL Trados, the two CAT tools both have their term bases.The Alignment ToolThe alignment tool allows users to align the original material andthe translation one by one. An exact match of translation and theoriginal material is usually need an artificial proofreading on alignment. The alignment unit can be a sentence the unit under a sentence, such as phrases and words. The alignment result can be imported to the TM term base, for later similar translation. (Qian Duoxiu, 2011)2. The comparison on CAT and human translation“With the development of globalization and science and technology, translation field received unprecedented impact. Increasingly global communication brings more opportunities for translation, greatly broaden the translation market. Translation in the 21st century has completelygot rid of the traditional concept and going to the tele-translation age with more dependency on the modern communication technology”. (Chen Yi, 2008)It is reported by ABI (Allied Business Intelligence Inc.) that, in 2003 global translation output was more than $13 billion, with 30% inAsia-pacific region, and the output of Chinese translation market was about billion RMB. In 2005, the output in the world was over $ billion, the output of translation market in Chinese mainland was 21 billion RMB. The demand of Chinese translation market is facing a trend of sharp expansion and translation industry is an emerging main force in China’s economy sector.Advantage of CATThe main advantage of CAT is that, it can make the translation activities traditionally based on thinking more smoothly and more quickly. (Jia Xinlan, 2003) It also has great impact on translators in doing other translation activities.Advantages are the following aspects:(1) It has the ability of helping the interpreter match the project and the sentence structure of the target language with the project andthe sentence structure of the source language very well. (Liang Ailin, 2004)(2) It has the ability of helping translators apply professional knowledge to the term sector surpass grammatical structures and vocabularies as well as the ability to make up texts. (Liang Ailin, 2004) By integrating the scattered and illogical professional knowledge,the can create a clear and normative text. For the interpreter, theprocess itself is also a kind of learning that not only the learning of knowledge and information, but also the learning of career experiences.With the amount of the emerging of multimedia database knowledge, all kinds of knowledge is no longer confined to take the form of text, but more intuitive to the form of sounds, pictures and animations, which is undoubtedly a revolutionary development for computer users that greatly improve the efficiency of accepting knowledge.(3) It has the ability of teaching and tutoring. Teachers can put the CAT into the training plan and training courses of the interpreter, to help interpreters accumulating translation experiences for guiding the following translations. (Liang Ailin, 2004)Limitations of CATThe chief drawback of CAT translation is that, sometimes, it can’t live up with scrutiny.CAT tools is more suitable for texts on science and technology which have high repetition rate.Only with the term base that TM has the room to work. CAT is not suitable for literary texts, because their rhetoric is rich and closely linked with the context. There is a lot of irony and extended meaning on irony in literature, with which the machine are incompetent. In addition, fuzziness of language will increase the difficulty to machine translation. For example, for a same word, the machine can make different semantic interpretation:(1)When turning over control, operators will switch to zero.机器翻译：当交到控制中时，操作员会转换到零位。
