During the process of completing this graduation paper, I have been
fortunate to receive much support, assistance, guidance encouragement from
many people.
First of all, I would like to express my deepest gratitude to my
supervisor – Ms Nguyen Thi Thu Huyen, M.A who has kindly given me
constructive comments, criticism, suggestions.
In addition, I would like to extend my thanks to the teaching staff of the
Department of Foreign Language at the Haiphong Private University for their
endless enthusiasm, valuable teaching.
I also wish to give my deepest thanks to my family who has been whole
heartly supporting me. They are always beside and motivate me in my study
and my life.
Finally, I also would like to thank all my friends for their discussions,
suggestions and encouragements. Without their instructive contributions, my
graduation paper could not have been finished.
