以下是一个三年级英语课前三分钟自我介绍的例子：
Hello, everyone! My name is [你的名字] and I am in the third grade. I am very excited to be here today and would like to introduce myself.
I live with my parents and my little sister who is two years younger than me. My favorite subject at school is English because I think it's interesting and fun to learn new words and expressions. In my free time, I enjoy reading books, playing with my friends, and watching movies.
I also love animals, especially cats and dogs. At home we have a pet cat named Whiskers who likes to take naps in sunny spots around the house.
When I grow up, I want to be a teacher just like our English teacher here in class. She is very kind and patient with us.
Thank you for listening to my introduction. Let's have a great class together!
