Hello, everyone! My name is [Your Name]. I am six years old and I study in Grade One at [School Name]. I am very happy to stand here today and say hello to all of you.

I have a round face and big eyes. My hair is black and short. I think I look like a little sunflower because I always smile. I like wearing colorful clothes, especially red dresses. They make me feel lively and cheerful.

At school, I love learning new things. My favorite subject is English because it’s so interesting. I enjoy singing English songs and reading simple stories. I also like playing games with my classmates during break time. We often play hide-and-seek or jump rope together. It makes me feel happy and strong.

My dream is to become an artist when I grow up. I want to draw beautiful pictures and create amazing stories for people to read. But for now, I need to work hard on my studies and practice more.

Thank you for listening to my introduction. I hope we can be good friends!

Goodbye!
