First of all, I would like to express my sincere gratitude to my supervisor, Ms.
Nguyen Thi Quynh Hoa for her generous assistance, enthusiastic guidance
and constructive supervision throughout my thesis. Without her help, this
graduation paper would not have been completed.
I also wish to acknowledge indebtedness to all the teachers at Faculty of
Foreign Languages, HPU for their valuable lectures and instructions during
the past years, which has helped me much in completing the final task.
I am grateful to HPU 2
nd
year English majors and all the English teachers for
their enthusiastic participation in completing my survey questionnaires.
