Based upon four self-built parallel corpora,the paper presents itself as a comparative study of the dependency distance between Chinese ST and English TT,between the works of the same style and between the works of different styles.The result shows that:(1)The dependency distance value(the DD value)of Chinese is much larger than of English;(2)English is a governor-initial language,while Chinese tends to be more governor-final;and(3)many factors,for example,the position of governors and dependents,the frequency of the connections between sub-clauses,difference in inflectional explicitation of C-E translations,concise purpose as well as translative styles have led to the difference in dependency distance between Chinese and English.
