A There are many kinds of friends. Some are always 1 you, but don't understand you. Some say only a few words to you, but understand you. Many people will step in your life, but only 2 friends leave footprints ( 脚印 ). I shall always recall ( 回忆 ) the autumn and the girl with the 3 . She will always bring back the friendship between us. I know she will always be my best friend. It was the golden season. I could see the yellow leaves 4 on the cool 5 . In such a season, I liked walking alone in the leaves, 6 to the sound of them. Autumn is a 7 season and life is uninteresting. The free days always get me 8 . But one day, the sound of a violin 9 into my ears like a stream ( 小溪 ) flowing in the mountains. I was so surprised that I jumped to see what it was. A young girl, standing in the wind, was 10 in playing her violin. I had 11 seen her before. The music was so nice that I listened quietly. Lost in the music, I didn't know that I had been 12 there for so long but my existence ( 存在 ) did not seem to disturb her. Leaves were still falling. Every day she played the violin in the corner of the building 13 I went downstairs to watch her performance. I was the only listener. The autumn seemed no longer lonely and life became 14 . 15 we didn't know each other, I thought we were already good friends. I believe she also loved me. Autumn was nearly over. One day, when I was listening carefully, the sound suddenly 16 . To my astonishment ( 惊讶 ), the girl came over to me. “You must like violin.” she said. “Yes. And you play very well. Why did you stop?” I asked. Suddenly, a 17 expression appeared on her face and I could feel something unusual. “I came here to see my grandmother, but now I must leave. I once played very badly. It was your listening every day that 18 me.” she said. “In fact, it was your playing 19 gave me a meaningful autumn,” I answered, “Let's be friends.” The girl smiled, and so did I. I never heard her play again in my life. I no longer went downstairs to listen like before. Only thick leaves were left behind. But I will always remember the fine figure ( 身影 ) of the girl. She is like a 20 —so short, so bright, like a shooting star giving off so much light that it makes the autumn beautiful.
