I was in charge of the entertainment of our class.
I used to be the representative of the course in Chemistry.
I was the member of the folk music,chorus and aerobics in school.

Hello,every one:

My name is xxx,and you may call me Ivy.As you see,I am very frank and friendly.Personally I think that I have the power of leadership and the ability of organization.At school,I used to be the art delegate and the chemistry delegate.A delegate means you are incharge of a certain subject.Also,I was a member of the school union of the folk instrument,singing group and body-shaping presentation team. And I think the experience on stage has become my treasure during my growth.Talking about my lesson,Chinese is my favourite subject.This is me,a very common student.
That's all.
Thank you all.
