阅读理解。 Vanilla is my best friend. She is a lovely girl with two big, beautiful eyes. But she always hides them behind a pair of black glasses. One day, though, I nearly ended our friendship. I remember that day clearly. We were sitting in class. The teacher was giving us our results for a Chinese test. I had done badly. I felt so sad that I wouldn't talk to anyone. At lunchtime, I even stayed in the classroom alone. Suddenly, I heard a voice. It was Vanilla. 'You look very unhappy,' she said. 'What's wrong?' I looked up at her, but said nothing. I knew Vanilla had got a good mark in the test. I thought she was making fun of me. I stayed silent (安静), but Vanilla didn't go away. She kept asking me questions: 'Is it because of the exam? Do you want me to show you the right answers?' I looked away from her. When I looked up again, Vanilla had gone. And so had my exam paper! I didn't know what to do. I looked everywhere for my paper, but couldn't find it. In the afternoon, Vanilla came up to my desk and gave me my exam paper back. I looked at it and got a big surprise. Vanilla had written the right answer next to every one of my mistakes(错误). My face went red. Vanilla had been trying to help me all along. How mean (卑劣的) I had been to her when she was being so nice. I wanted to hug her, but all I did was to hold her hands and said, 'Thank you.' That afternoon, Vanilla and I walked home together. I felt so happy that I had to thank her again.
