During the process of implementing this graduation paper, I have received a great
deal of help, guidance and encouragement from my teachers, family and friends.
First of all, I would like to express my deepest gratitude to Ms. Dao Thi Lan
Huong (M.A) – my supervisor for her assistance and guidance during this
challenging process. She has generously given me valuable suggestions, advices
as well as comments about my study. I myself find that this thesis cannot come to
an end without her enthusiastic supports.
Next, I also would like to express my sincere thanks to all the teachers of Foreign
Languages Department of Haiphong Private University, who have thoughtfully
trained me in the last four years.
My special thanks are also sent to my dear friends who willingly helped me in
carrying out the survey and made the great contribution to my topic by giving
ideas, comments, suggestions which are very useful for my research.
Last but not least, I would like to give my wholehearted thanks to my family who
have stood behind me throughout this entire process. I truly could not comp lete
this paper without their love, support and encouragement.
