Dear Chairman,

I am a boy of Class Eight, Grade Nine. I’d like to be a member of the Helping Hands Club. I am in good health. I like studying and always work hard at my lessons. I think it’s our duty to care about others around us, so I often help people in need. Besides , I get on well with my classmates and often help them with their lessons. On my way home, I often help old people cross the street. On the bus, I always offer my seat to women with babies or the needy people. Sometimes, I pick up rubbish in the park to make our city cleaner.

    If I join the club, I will be able to do more for others. I’ll be glad if I could be accepted. I am waiting for your reply. 

                                                     Yours sincerely,
