In particular, special thanks to Miss.Kanitha Wuthiya and my subjects of this study were the 4th year students Major in English for International Communication at Rajamangla University of Technology Isan, Surin Campus. I could not have concluded my study without the data and information supplied by them. Finally, I would like to express my sincere gratitude to my beloved family, who has always supported me in both my happy and difficult times. They will always be important people in my life giving me strength and encouragement to achieve my goals.
