In the process of completing this graduation paper, I have faced up with many
problems with lexicology, as well as the way to express my ideas. However,
with the great help, assistance and encouragement from teachers, family and
friends; I have overcome these difficulties and completed this graduation paper
successfully.
First of all, I would like to express my deepest gratitude to Mrs. Pham Thi Bich
Ngoc, M.A and Mrs. Dang Thi Van, M.A, my supervisors who have not only
given me many invaluable suggestions and comments but also provided me with
valuable materials.
Secondly, I am deeply grateful to Mrs. Nguyen Ngoc Lien, M.A – Dean of
Foreign Language Faculty of Hai Phong Private University whose criticism and
advices have improved my study.
