I have a good brother. I like him very much. My brother is a student. His name is Nick and he is nine years old. He has a round face, two big eyes and short black hair. He likes wearing his jeans and T-shirt, because he thinks he’s cool in them. He is very clever and likes playing football very much. We often do our homework, play computer games and football together after school. He is very kind and usually helps others. This is my brother.
