The study would not have been accomplished if without the help from several people. First of all, I would like to thank Teacher Piyaporn Promtha for her wealth of ideas and guidance stimulating me to gain an insightful idea to develop the study. I deeply appreciate her help to encourage me through the entire work.
I was very fortunate to have many friends both with in the same school and class. I thank them all for their being very supportive.
I would like to thank all of the teachers in Foreign languages Department of Satreesiriket School for their help with my study.
I am deeply indebted to my family, specifically, the cheerfulness and love of my mother and father which is a valuable thing for my mental feeling to pursue my endeavor.
