After a quick breakfast, I went into the lecture hall in a hurry．A famous teacher was  to the students．He was holding up a $100 bill．Then he said to the three hundred students，“Who would like this $1 00 bill?” The students put up hands at once．Then he said，“I am going to give this $100 bill to one of you，but ，let me do this．”He made the bill into a ball．Then he said. “Who it now?” The hands went back into the air．“Well,” he said，“what if I do this?” and he  it on the floor and stepped on it．He picked up the bill and said．“Who still wants it?” Hands went back again into the air．
“My friends,” he said，“you have learned a valuable(有价值的) today．No matter what I did to the $100 bill! Many   in our life，we are dropped and stepped on．We feel as if we are worth nothing．But remember, no matter what   happened to you，you will never lose your value：You are  valuable to those people who love you．Your value doesn’t come from what you do or whom you know, but who you are．’’
