假设你是李华,你们学校志愿者协会招募新成员,打算在假期到本市儿童医院和敬老院组织志愿者活动,你决定去其中一个地方去做志愿

Dear Chairman,
I am li hua,a student from class fiwe,Grade three.l know that you want new members for your volunteer group and l want to be one of them.I want to help the old because I think they are so old that they can not do some physical job ,such as cleaning the room,washing clothes and so on.Besides I can sing or dance for them in order to make them happy .I think it a duty for us to help the old .And it is also a pleasure for us.
