In the process of completing this graduation paper, I have received a
great deal of help, advice, guidance and encouragement from many teachers,
friends and my family. It is my great pleasure I have got.
First of all, I wish to express my deepest gratitude to my supervisor,
Nguyen Thi Hoa, M.A for her constant support, various materials, precious
advice and valuable comments on draft chapters to complete this study. This
would not have been possible without her supports.
Besides, I would like to extend my sincere thanks to Hai Phong Private
University for providing us professional learning environment and facilities as
well as all the teachers in Foreign Language Department for their useful
lessons, teaching, guidance, experience sharing with the kind heart and whole -hearted instruction and giving enthusiasm, sympathies to lift us to be better ones
as we are today.
