One day a famous speaker gave a speech to a crowd of people. He held up a 21 bill. He asked, “Who would like this $20 bill? Hands were 22 .” 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 23 . He then asked the audience, “ 24 still wants it?” Still the hands went 25 in the air.

“What 26 I do this?” He asked, and he 27 it on the ground, and started to step on it. He 28 it up. Now the bill was 29 and crumpled. “Now who still wants it?” Still the hands went up.

“My friends,” He continued, “You have all 30 a good lesson. No matter 31 I did to the money, you still wanted it because the bill did not lose its 32 . It was still worth$20. Many times in our 33 , we are dropped, crumpled, and stepped on, because we sometimes 34 wrong decisions, or we may 35 with something we do not 36 . When what happens, we feel depressed and think we are 37 . 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 38 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 39 , but on its inner value. This is the 40 of life.”
