英语自我介绍（Self-Introduction）
Hello everyone! My name is Li Hua, and I am 14 years old. I come from Nanjing, a beautiful city famous for its history and lakes. I am now a student in Class 3, Grade 8 at Sunshine Middle School. I’d like to share something about myself.
I am an outgoing and friendly person. In my free time, I enjoy reading books and playing basketball. Reading helps me explore different worlds, and basketball teaches me teamwork. My favorite subject is English because it allows me to communicate with people from other countries. Although it’s sometimes challenging, I believe "practice makes perfect" .
I also love music. I have been learning the piano for 5 years, and it brings me joy. Last month, I even won a prize in a school music competition! Besides, I’m good at math. Solving problems feels like an exciting game to me.
My family is small but warm. My father is a doctor, and my mother is a teacher. They always encourage me to try new things. On weekends, we often cook together or go hiking.
My dream is to become a scientist in the future. I want to invent useful things to help people. To achieve this, I will study harder and never give up.
Nice to meet you all! Let’s be good friends and learn from each other!

大家好！我叫李华，今年14岁。我来自南京，这是一座以历史和湖泊闻名的美丽城市。我现在就读于阳光中学八年级三班。我想和大家分享一些关于我的事情。
我是一个外向且友好的人。空闲时，我喜欢读书和打篮球。阅读帮助我探索不同的世界，而篮球教会我团队合作。我最喜欢的科目是英语，因为它让我能与世界各地的人交流。尽管有时很难，但我相信“熟能生巧”。
我还热爱音乐。我学钢琴已有5年，音乐带给我快乐。上个月，我甚至在学校音乐比赛中获奖！我擅长数学，解题对我来说像一场刺激的游戏。
我的家庭虽小但温馨。父亲是医生，母亲是教师。他们总是鼓励我尝试新事物。周末我们常一起做饭或爬山。
我的梦想是未来成为科学家，发明有用的东西帮助他人。为此，我会更加努力学习，永不放弃。
很高兴认识大家！让我们成为好朋友，互相学习吧！
