Good morning everyone! My name is Li Xiaoming, and I am 14 years old. I study at Sunshine Middle School. I am an outgoing and friendly person who loves making new friends. My hobbies include playing basketball, reading books, and listening to music.
In school, my favorite subjects are English and science. I find English interesting because it helps me communicate with people from different countries. Science is fascinating because it teaches me how the world works. I always try my best in class and enjoy participating in group activities.
I have a happy family of three: my parents and me. My father is a teacher, and my mother works in a hospital. They encourage me to study hard and be kind to others. On weekends, I often help my mother with housework, like cleaning the room or watering the plants.
I also joined the school basketball team last year. Through this experience, I learned the importance of teamwork. Even though I’m not the best player, I never give up and keep practicing.
I hope to improve my English skills and make more friends here. Thank you for listening!

大家好！我叫李晓明，今年14岁，就读于阳光中学。我是一个外向且友好的人，喜欢结交新朋友。我的爱好包括打篮球、阅读和听音乐。
在学校里，我最喜欢的科目是英语和科学。我觉得英语很有趣，因为它能让我与不同国家的人交流；而科学让我了解世界的运作方式。我总是在课堂上全力以赴，并喜欢参与小组活动。
我有一个幸福的三人家庭：父母和我。父亲是老师，母亲在医院工作。他们鼓励我努力学习并善待他人。周末时，我常帮妈妈做家务，比如打扫房间或浇花。
