One day a famous speaker gave a speech to a crowd of people. He held up a   36   bill. He asked, “Who would like this $20 bill ? ” Hands were   37  . Then he said, “I am going to give this $20 to one of you, but first let me do this.” He began to crumple（弄皱）the   38 . He then asked the audience, “   39  still wants it ?” Still the hands went  40 in the air.
“ What   41  I do this? ” He asked, and he  42  it on the ground, and started to step on it. He   43  it up. Now the bill was  44  and crumpled. “ Now who still wants it?” Still the hands went up.
“My friends,” He continued, “You have all  45   a good lesson . No matter   46  I did to the money, you still wanted it because the bill did not lose its  47  . It was still worth $20. Many times in our   48 , we are dropped, crumpled, and stepped on, because we sometimes 49  wrong decisions, or we may   50  with something we do not   51 .When that happens, we feel depressed and think we are   52 . But in fact no matter what has happened or what will happen, you will never lose your value. The worth of our life comes not   53  what we do or whom we know, but in who we are! Don’t forget ‘the worth of a thing does not depend on its outside   54  , but on its inner value.’ This is the   55  of life.
