First of all, I would like to give

First of all, I would like to give my heartfelt thanks to my supervisor, Professor Liu Yuanfu, for his kindness, illuminating guidance and profound knowledge. From his insightful and lively lecture, I have obtained a better understanding of translating theories and thus developed interest in it. Working on a very busy schedule, he still give my paper a careful reading and detailed comments. Without his keen insights and constant encouragement, it would not have been finished.I also express my appreciation to all teachers who have lectured me for their insightful lectures which are of great benefit to me in my research.Especially this thesis owes a debt to my colleagues, Yi Qiaoling Zhao Tingting and Yang Bo who work with me give me substantial support and urge me to do better in language study and research.Finally, my cordial thanks also go to my family member and friends who love and care me and whom I love and care.
