完形填空；从A、B、C、D四个选项中选择填入空白处的最佳答案。
Once my father and I went to see a circus (马戏团). A family was standing in front of us 1 for tickets. The family had eight children. Their clothes were not 2 but they were clean. They were talking about the clowns（小丑）and elephants excitedly.
“I want 3 tickets, eight for children and two for adults（成人）.” said the father to the ticket lady.
The ticket lady told him the 4 . When he heard that, the man couldn’t believe his 5 . He asked again, “How much?”
The ticket lady spoke again. The father looked sad. Clearly, he didn’t have 6 money. My dad took a $20 bill（纸币） and dropped it on the ground. Then he 7 the bill, and said to the man, “Sir, this fell out of your pocket.”
The man knew what was 8 on. He looked into my dad’s eyes and took the 9 . “Thank you, thank you, sir. This 10 means a lot to me and my family.”
We didn’t go to the circus that night, but we didn’t feel sorry for it at all.
