Good morning, everyone,
It's great honor for me to speak here. My name's Li Xiaojun, born of a harmonious family. My
father and mother are all high school teachers.Influenced by them, I read widely during my early age,
but I've developed a great interest in arts and sports. I'm easygoing, get along well with my classmates.
It is this personality which helps me win over all my classmates' friendships, and also help me
overcome many difficulties both in academic and personal life. Being admitted in your university has
always been a beautiful dream for me. I dream constantly that I, along with mine classmates, will study
happy with the help of the respectable professors；I dream that I will swim freely in the sea, enjoying
the waves of knowledge.
I hope all my dream will come true in the near future.
Thank you.
