Dear Chairman,
I'm a student from Class 1,Grade 3.I want to join in your club.At school,I study very hardly.I'm always ready to help others.I got along with my classmates but I like to help them with their lessons.I often help the old across the road .On the buses,I often give my seat to others.On weekends ,I usually go to the park pick up rubbish.I want to join a club very much.For one reason,I like to make friend and work with others.For other,I will have more chances to help others.I would be glad if accepting.
Yours,
Li Ping
