Abstract: As the essential part of a clause, Theme and its choice in Chinese-English consecutive interpretation (CI) concern the quality and speed of interpreting. Based on Halliday’s theory of Theme and Rheme, this paper studies the similarities and differences between Chinese and English Themes, discusses the ways to maintain or change the Themes, and probes into the underlying reasons in this process. The findings of this research is believed to be useful in providing reliable methods and assessment for CI.
