teachers, families and graduates, welcome and thank you for joining us tonight at Xinhua High School graduation ceremony for the Class of 2011! First, I’m glad to thank all our families and friends for their love and support on behalf of the graduates.
I also want to thank our hardworking teachers for guiding us through to this moment. My personal thanks to Mr Liu, you got me through Math when I had lost hope. Graduation is a time to go over enjoyable memories which have been made over the past three years. Many events become so vivid in my mind at this moment, such as military training, soccer and basketball games.
But graduation is also a time to look forward to the future in front of us. No matter what you want to do next, I hope you can try it clearly. I believe we’ll go smoothly in the future if we work hard.
Eventually, all the best to the Class of 2011. Thank you very much.
