Friends are very important in everyone's life because friends are always there when we need them. It's great to have many friends, and I can't think about my life without my friends.

　　My best friend is Lisa. When I first met her, I was five. She is one year older than me. Now she is in the same class with me, in the 7th grade. She is tall and quite thin. She has long curly blond hair and blue eyes. I am not so beautiful. Sometimes I wish I could be as beautiful as she is.

　　My name's Molly. I am tall enough but a little fat. Lisa and I like doing a lot of things together and talking about different things. She always helps me with my math and I sometimes help her with her English and history. I had to do a report (报告) on science once, but I didn't understand (理解) what the teacher said. The next day, I read it in front of the class. But the teacher told me that my report was wrong and all my classmates laughed at (嘲笑) me. I felt very bad about myself. Lisa was the only one who didn't laugh at me. She tried to be nicer than anybody else and make me happy.

　　I am a shy person and sometimes I feel that people don't understand me. Lisa is friendly and everybody loves her. She is also smart and she can deal with (解决) everything. I am happy to have a friend like her.
