Jim, a successful businessman, told the experience of his childhood.

When he was 12, his parents       . He was alone and didn’t get on well with others. People always laughed        him. No one showed kindness (友善) to him. His only friend was a dog named Tige.

One day as he walked down the street, a young lady was walking in front of him. Suddenly one of her bags dropped from her arms. As she stopped       , she dropped other bags. He came to help her.“Thank you, dear! You are a nice little boy!”She said kindly, smiling.

A special feeling came to him. These were        kind words he had ever heard. He watched her        she went far away, and he whistled(吹口哨)to his dog and went directly to the river nearby.

“Thank you, dear! You are a nice little boy!”he repeated the woman’s words. Then in a low        he said to his dog,“You are a nice little dog!”Tige raised        ears as if(似乎)it understood.

“Uh! Even a dog likes it!”he said,“Well, Tige, I won’t say unkind words to you any more.”Tige waved its tail happily.

The boy thought and thought. Finally he looked at himself in the river. He saw        but a dirty boy. He washed his face       . Again he looked. He saw a clean nice boy. He was amazed (震惊). From then on, he had a new life.

After telling this, the businessman stopped for a while, and then he said,“Ladies and gentlemen, this is the place where that kind woman planted in me the first seed (种子) of kindness. All of us should learn about kindness.        a great power it has!” If you show kindness to others, you will be an able man.
