Title: My Favorite Boy

I have a good friend who is a boy. His name is Jack. He is 10 years old and has black hair and big eyes. He is very smart and looks handsome. I am proud of him because he can get perfect scores in Chinese, math, and English.

Jack is a hardworking student. He likes reading and playing football. He is also good at swimming and is a member of our school's Swimming Club. But what makes him stand out is his kindness and politeness.

Jack is always ready to help others. For example, last Friday, when the traffic lights were red, he helped an old woman cross the road. He is always polite and respectful to everyone he meets. All of the teachers and classmates like him very much.

In a word, Jack is a remarkable boy who is not only academically gifted but also has a kind heart. I am glad to have him as my friend.
