我最好的朋友：

I have a best friend. Her name is Lucy. She is a kind person. If someone needs help, she will give him a hand. She helps me a lot. When I am sad, she will be by my side and talk to me. My math is poor, and hers is good，so she often teach me how to study math. With her help, my math improves. I am so glad to have such a good friend.
