Dear Sir or Madam,
How are you doing? I am Li Hua, a 17-year-old teenager, who is crazy about different cultures around the world. Recently, I learned in your official website that a volunteer is needed for an exhibition of Chinese traditional painting in London. So I am writing to apply for this position.
Here are three main reasons why I am the best choice for you. First and foremost, having lived in London for half a year before as an exchange student, I am undoubtedly good at EnglIsh; as a result, it is a piece of cake for me to introduce everything to international friends. Besides, I learned Chinese painting for more than ten years in my childhood; therefore, I do know a lot about this great art form. Last but certainly not least, as vice monitor of our class, I am kind, patient and always ready to help others.
Hopefully, this wonderful chance would be offered to me. I have the confidnece that I will have a great time. Looking forward to your reply.
