Good morning, everyone. 

I’m Li Hua. It’s my great honor to stand here to deliver my speech. It has been three years since I started my high school. At this moment, I cannot bear to part but I am also eager for my new life in university. During the three years, not only have I made some true friends who shared sorrows and joys with me, but also I have gained various knowledge. 

Before leaving, I’d like to express my sincere gratitude to my teachers. It was they who patiently answered our endless questions. Besides, I owe many thanks to my dear classmates. Without their help and encouragement, I couldn’t have overcome so many difficulties. Now I’ve been determined to lead a more meaningful life in university and I will live up to the expectations of my teachers and my parents. 

Thank you for your listening.
