    I'm a 17-year-old senior student from China. While surfed the Internet, I have found that your organization will hold a summer camp in Singapore. With greatly interest, I'd like to apply for them. I'm an outgoing girl who like communicating with others. I could speak English well. My written English is excellent, either. I wish to join in the activities. For one thing, I'm willing to introduce China to other students from all over world; for another, I expect to learn from more about other countries.
