在线课程【答案】Dear Mr. Zhang,
My name is Li Hua, a student in Hongxing Senior High School. Knowing that Beijing Marathon will be held in 2019 on the official website of Beijing Marathon Organizing Committee, I am so excited that I can’t wait to be a volunteer.
As a sports-lover myself, I have a general idea of the rules of different marathons. In addition, I am also good at communicating with others and eager to lend a hand to people in need. With the spirit of voluntary work rooted in my heart, I have been a volunteer in many activities and I am sure that I can be a suitable volunteer you need. If I am honored enough to be accepted as a volunteer, I will serve the runners heart and soul, using my patience and carefulness to make them feel at home.
Look forward to hearing from you.
Yours sincerely,
Li Hua
