【正确答案】Dear Sir/Madam, I want to apply for joining the school Students' Union. It's a good way to improve my all-round abilities and can help me know more about the school culture and management. I often surf on the Internet for something new. I love sports and pop music. I do quite well in English and can talk with foreigners freely. I'm very proud of it. I hope to join the Department of Entertainment. I'm interested in it. I'm sure I will work hard and help organize many kinds of school activities. Thank you ! Yours, Lin Jing
