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．"
