Vanilla is my best friend. She is a lovely girl with two big, beautiful eyes. But she always hides them 1 a pair of black glasses.

    One day, however, I 2  ended our friendship. I remember that day clearly. We were 3  in the classroom. The teacher was giving us our results of a Chinese exam. I had done badly. I felt so 4 that I wouldn't talk to anyone. At lunchtime, I even stayed in the classroom alone. Suddenly, I heard a  5. It was Vanilla. “You look very unhappy,” she said. “What's wrong?” I looked at her for a while, but said  6. I knew Vanilla had got a good mark(分数) in the exam. I thought she was  7 me. I sat silently, but Vanilla didn't go away. She  8 asking me questions: “Is it because of the exam? Do you want me to tell you the right  9?” I looked away from her. When I looked up again, Vanilla had gone. And so had my exam paper! I didn't know 10 to do. I looked for my paper everywhere, but couldn't find it.

    In the afternoon, Vanilla came up to my desk and 11 me my exam paper back. I looked at it and got a big 12. Vanilla had written the right answers next to every one of my mistakes. How  13 she was! My face turned red. I wanted to hug her, but I only held her hands and said, “Thank you.” That afternoon,  14 Vanilla and I were on the way home, I felt quite happy and thanked her again. We are  15 best friends.
