AcknowledgementsI am very grateful to have this opportunity to extend my best regards to whoever has helped me with my thesis
Firstly, I would extend my heartfelt gratitude to my supervisor, prof
for his continuous support and inspiring instructions
I am inspired by his persistent patience and kind encouragement
Without his generous guidance and constructive revision, this paper would have never been finished
Secondly, I would like to express my deepest gratitude to my friends at the same group
Then, all the other teachers in our School of Foreign Languages also influence me greatly
It is they who give me lectures which have benefited me a lot and provided inspiration for my thesis
Last but not least, I would give my thanks to School
Thanks for giving me this chance to achieve
