阅读理解 My first performance in front of the audience was coming up soon． I tried as hard as I could to remain calm, but my heart was racing．I stared down at my sweat-covered, shaking hands． I looked up again at the audience, realizing that these were real people．They were not just my mum and dad, who would say, “Good job!” even if I messed up the entire piece． What if I had the wrong music? What if I played the wrong notes? As it turned out, I was never able to answer these questions because the spotlight(聚光灯)was waiting for me．I grasped my hands tightly together, drying off the sweat． Slowly I walked to the mud-brown piano in the center of the room．It contained 88 demanding keys, which were waiting impatiently to be played．I swallowed the golf-ball-sized lump(隆起部分)in my throat and sat down．Slowly, I opened the music．Next, I rested my still shaking hands on the ivory(象牙色的)keys． As my fingers played across the keys, I was becoming more unsure of my preparation for this moment．But the memory of my years of training came flooding back．I knew that I had practiced this piece so many times that I could play it backwards if requested． Although at one point I accidentally played two keys instead of the intended one, I continued to move my fingers automatically(自动地)． My eyes burned holes into(were fixed on)the pages in front of me． There was no way that I was going to lose my concentration．To keep this to myself, I leaned forward and focused carefully on the music． When I came to the end of the page, a warning went off inside my head：DON’T MAKE A MISTAKE WHEN YOU TURN THE PAGE! Needless to say, I obeyed myself with all my heart and mind．And, proud of my “page-turning” feat(技艺), I finished the rest of the piece without making a single mistake． After the final note died away, a celebration went into action inside my head．I had finished．I had mastered the impossible． |
