Good afternoon (morning), professors：

　　It is my great pleasure to be here. My name is XXX, graduated from XX University of Technology, majored in Petroleum Engineering. During my four-year study in the university as an under-graduate student, I have built up a solid foundation of professional knowledge, as well as a rich experience of social activities. Four years' university education gives me a lot of things to learn, a lot of chances to try, and a lot of practices to improve myself. It teaches me not only what to study and how to think, but also to see the importance of practical ability (such as doing experiment as much as possible). In the university life, I have made many good friends. They help me improve my study and research ability, and often give me good example to follow.
