Everyone needs friends. A good friend should be a friend in need. He will never leave you alone (独自) when you are in trouble (麻烦).
I have a best friend like this, and her name is Rachel. She and I are both 12 years old. We became good friends four years ago.
She has black and short hair, a little mouth and two big eyes. She is very smart. Her parents are both math teachers in a school. They love her very much. Her friends like her, too. So she is happy every day.
She studies very hard. She is good at English. She likes to speak English She can speak English very well. She always says, "Learn by doing. "So she thinks speaking is very important in learning English. But her favorite subject is Chinese. We have the same hobby (爱好). We like playing the piano.
I like Rachel very much. When I am sad in trouble, she never laughs at me. She always tries her best to make me happy-she tells me funny jokes (笑话) and plays the piano with me. She helps me solve 解决) problems. So I will not feel worried any more. When I make mistakes (犯错), she asks me to correct them in time. So I never make any big mistakes. This is what a friend should do. I am lucky to be her friend.
