英语作文，急！！！拜托各位了

Dear Sir/Madam,
As a student,I want to be a volunteer to help people especially the old.And I'd like to visit old people's home for I always get along well with my grandparents and I am good at communicating with the old people.Besides,I can help them clean the room and cook a meal for them which I usually do at my home.Therefore,I am sure that I will successfully finish the task.
In addition,I would like to help clean up the City Park for it can not only help protect the environment but also remind people of environmental awareness to give a good example to them.And I will bring a besom to sweep the ground and a dish rag to clean the public accommodations like the rest room and dining hall.
I hope that you can permit my request.Thank you!
Yours sincerely
