The present research makes an attempt at an investigation of the translators' styles of the two English versions of Huo Xiaoyu Zhuan in a corpus-based approach.With the help of WordSmith,a corpus retrieval and analysis suite,the data about the word length,lexical density,readability and so on are collected from the two translated texts and a comparable native English speaker corpus,and then these data and the samples of translation are compared and analyzed both quantitatively and qualitatively,which leads to the findings of the translation styles of the two translators.The corpus-based study of translator's style is both empirical and scientific,and its findings,therefore,can provide a solid foundation for translation criticism and find application in translation teaching and translator training.
