| One day a famous speaker gave a speech to a crowd of people. He held up a 20-dollar bill. He asked, "Who would like this $20 bill" Hands were raised. 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 1 . He then asked the audience (观众), "Anybody still wants it?" Still the hands went 2 in the air. "What if I do this?" He asked, and he 3 it on the ground, and started to step on it. He 4 it up. Now the bill was 5 and crumpled. "Now who still wants it?" Still the hands went up. "My friends," He continued, "You have all learned a good lesson. No matter 6 I did to the money, you still wanted it because the bill did not lose its 7 . It was still worth $20. Many times in our 8 , we are dropped, crumpled, and stepped on, because we sometimes 9 wrong decisions, or we may 10 with something we do not 11 .

The worth of our life comes not 13 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 14 , but on its inner value.' This is the 15 of life. | ||||
