Once my father and I went to see a circus(马戏 ). A family was standing in front of us         for tickets.

The family had eight children. Their clothes were not        but they were clean. They were talking about the clowns(小丑) and elephants excitedly.

The ticket lady spoke again. The father looked sad. Clearly, he didn’t have         money.

My dad took a twenty—dollar bill and dropped it on the ground.Then he picked         , and said to the man, “Sir, this fell out of your pocket.”

We didn’t go to the cirus that night,but we didn’t feel sorry for it at all.
