Hello, everybody. I should like to offer myself as chairman of the student’s union. Let me introduce myself.

My name is Li Hua, and I come from Class 302 Grade2. I like playing basketball and I’m fond of singing. I think I’ve got many advantages for the position. I’m always ready to help others and get along well with others. If I’m offered the position, I will try my best and do everything I can for the student’s union. I’m sure I’ll be a good chairman. I hope to get support from you. That’s all. Thank you.
