      My first performance in front of an audience was coming up soon. I tried as hard as I could to remain
(保持)   1  , but I had an empty feeling in my stomach. I stared down at my sweat covered,   2   hands. I
looked up again at the audience, realizing that these were   3   people. They were not just my mum and dad,
who   4   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   5 , I was never able to answer these questions because the spotlight was 
  6   for me. I grasped my hands tightly together, drying off the sweat. Slowly I walked to the mulberry
piano in the   7   of the room. It contained 88 demanding keys, which were waiting impatiently to be played.
I swallowed the golf ball-sized lump (隆起的) in my throat and sat down.   8  , I opened the music. Next,

more   9   of my preparation for this moment. But the memory of my year of training came flooding back.
I knew that I had practiced this piece  10  that I could play it backwards if  11 . Although at one point I
accidentally played two keys  12  the intended (预先, 打算的) ones, I continued to move my fingers
automatically (自动的). My eyes burned holes into the page in front of me. There was no  13  that I was
going to lose my concentration. To keep this promise to myself, I leaned (倾斜)  14  and focused carefully
on the music.  15  I came to the end of the page, a warning  16   inside my head: DON'T MAKE A
MISTAKE WHEN YOU TURN THE PAGE! Needless to say, I  17  myself with all my heart and mind. And,
proud of my "page- turning" feat (技艺) I finished the  18  of the piece without making a single mistake. After
the final note died away, a celebration went into action  19  my head.I had finished. I had mastered (征服)
the  20 .
