Abstract: This paper aims to analyze the main functions and limitations of machine translation (MT) of journalistic texts between English and Chinese. The analysis is based on computer-aided translation (CAT) and discourse analysis theory with the application of MT in journalistic texts in recent years as the breakthrough point. Through the comparison between MT and human translation (HT), the paper proposes combining MT and HT to make the translation of journalistic texts more rapid and more efficient. 

Key words: machine translation (MT), computer-aided translation (CAT), discourse analysis, news translation
