Electric shock

Injuries caused by electric shock are fairly common. When a person has received an electric shock, no one should go near him/her until the current has been turned off. If a shock occurring at work or at home causes someone to lose consciousness（知觉）, electrical connection must be broken before anyone tries to give assistance. You should either turn off the switch at the mains or, if that is not possible, push the person away with a dry piece of wood.

Look out for signs of shock. People who have been injured or who may have lost a lot of blood, or those who have had heart attacks, may be in deep shock. The signs to look for are faintness, paleness, a moist, sticky skin, shallow, rapid breathing and a fast but weak heartbeat.

Shock can prove fatal, and it is essential to do something to prevent its developing. The best way to treat or prevent shock is to keep the patient lying down, better with the legs higher than the head; if possible, raise the lower part of the body on a rolled-up packet or similar object. Make the patient as comfortable as possible, loosening any tight clothing, and comfort him/her because fright increases the effects of shock.

My first performance in front of an audience was coming up soon. I tried as hard as I could to remain    36    , but I had an empty feeling in my stomach. I stared down at my sweat covered,     37      hands. I looked up again at the audience, realizing that these were    38    people. They were not just my mum and dad, who     39    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    40    , I was never able to answer these questions because the spotlight was    41    for me. I grasped my hands tightly together, drying off the sweat. Slowly I walked to the mulberry piano in the     42    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.     43    , I opened the music. Next, I rested my still shaking hands on the ivory keys. As my fingers played across the keys, I was becoming more     44     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     45    that I could play it backwards if     46     . Although at one point I accidentally played two keys   47    the intended one, I continued to move my fingers automatically （自动的）. My eyes burned holes into the page in front of me.  There was no     48     that I was going to lose my concentration. To keep this promise to myself, I leaned     49    and focused carefully on the music.     50     1 came to the end of the page, a warning     51     inside my head: DON' T MAKE A MISTAKE WHEN YOU TURN THE PAGE! Needless to say, I     52      myself with all my heart and mind．And, proud of my "page- turning" feat（技艺） I finished the     53    of the piece without making a single mistake.  After the final note died away, a celebration went into action     54     my head.1 had finished.I had mastered （征服）the
