在比赛自我介绍的时候，如何用英语表达出自己的个性和特点，让评委和观众印象深刻呢？

首先，要非常清晰地介绍自己的姓名和身份。比如说，可以说：“Good afternoon, ladies and gentlemen. My name is Lisa, and I'm a college student majoring in English.”

接下来，可以介绍自己的兴趣爱好和特长。比如说：“In my free time, I love playing soccer and basketball. I’ve been playing soccer since I was six years old, and I’ve even won a few championships with my team.”

除此之外，还可以介绍一些关于自己的趣闻和轶事，让评委和观众更好地了解自己的个性和特点。比如说：“I’m also a huge fan of Harry Potter. I’ve read all the books and seen all the movies at least ten times each. And, fun fact, I once dressed up as Hermione Granger for Halloween and won first prize in a costume contest!”

最后，要强调自己的目标和意愿，以及为什么参加这个比赛。比如说：“I’m participating in this competition because I want to challenge myself and improve my public speaking skills. My ultimate goal is to become a successful writer and speaker, and I believe this competition will help me achieve that.”

总之，在比赛自我介绍中，要展现出自己的自信和个性，让评委和观众感受到你的热情和魅力。
