One possible version: Dear Sir/ Madam, I hear the Chinese and American Students' Summer Camp will be held in Hawaii. I am interested in this summer camp and hope to join in. I am a 15-year-old Chinese middle school student. I am learning in Beijing No. 36 Middle School. English is my favorite subject. I also do well in other subjects. I like reading and often go swimming in my school's swimming pool. I would like to join the summer camp because I want to improve my English by practising it with American students. To know more about different people and countries will be good for my language study. I am sure I will make a lot of friends there. Seeing the good scenery in Hawaii is my dream from the childhood. Hope I can get the chance.
