In the process of doing the graduation paper, I not only have faced u p with many
problems in analyzing techniques in improving writing English business letters, collecting
reference materials but also difficulties in choosing the right way to express my idea. However, I
have received a lot of guidance, assistance, and enthusiasm from my supervisor, Ms. Nguyen Thi
Thu Huyen and other teachers in Foreign Language Department of Hai Phong Private
University. Thanks to these helps, I have overcome the difficulties and completed my graduation
paper successfully.
I wish to express my deepest gratitude and indebtedness to my supervisor Ms. Nguyen Thi
Thu Huyen who has always been most willing and ready to give me valuable advices,
suggestions and materials to finish this study. I would like thank all teachers of Foreign
Language Department of Hai Phong Private University for their precious and useful lessons
during my four – year study which is then the foundation of this graduation paper.
