　　Dear Mr Liu，

　　I want to work as a volunteer （志愿者）in the home for the elderly .

　　I study hard. I'm good at singing and dancing. I like telling funny jokes and always make my friends laugh happily. I'm friendly and cheerful. I'm ready to help others. I think we should care about the old. They need our help.

　　I hope I can come to the home for the elderly to help more old people. Every weekend，I would like to cook food and do some cleaning for them. I can help them with their problems.

　　I look forward to hearing from you soon.

　　Yours，

　　Xia Hua
