【答案解析】Dear Sir/Madam,
I have heard that a service team which aims to help the old and the handicapped will be organized in our community. I am very interested in it and want to join the team.
I now study in Beijing Normal University and my parents live here. It is known to all that it is a virtue to help others in need. As a college student, I am eager to do something for the society. Helping others is meaningful in that we not only bring others convenience and strength but also gain pleasure and satisfaction for ourselves. Therefore, please allow me to join the team. I will certainly try my best.
I am looking forward to your early response.
