完形填空。

     Tess was an eight-year-old girl when she heard her parents talking about her sick brother, Andrew.
Only a   1   surgery could save him now and no one would   2   them the money. She heard Daddy say
to her tearful Mother with   3 . "Only a miracle can save him now."
     Tess went to her bedroom and   4   a glass jar from the closet. She poured all the change out on the
floor and counted it   5  . No chance here for mistakes. Placing the coins back in the jar, she   6   out
of the back door and made her way 6   7   to Rexall's Drug Store.
     She waited   8   so long but the pharmacist was too busy at this moment.
     "And what do you want?" the pharmacist asked in a(n)   9   tone of voice. "I'm talking to my brother
from Chicago whom I haven't seen for ages," he said.
    "Well, I want to talk to you about my brother," Tess answered. "He's really, really sick and I want to
buy a  10 ."
     "I beg your pardon?" said the pharmacist.
     "My brother has something bad growing  11  his head and only a miracle can save him now. So how
much does a miracle cost?"
     "Sorry, little girl. We don't sell miracles here." he said,  12  a little.
     The pharmacist's brother  13  down and asked her "What kind of a miracle does your brother need?"
"I don't know," Tess replied with her eyes  14  up. "He needs an operation. But my Daddy can't pay for it,
so I want to use my money."
     "How much do you have?" he asked."One dollar and eleven cents," she  15 . "It's the exact price of a
miracle for little brothers. Take me to  16  your brother. Maybe I have the miracle you need."
    That well-dressed man was Dr Carlton Armstrong, a surgeon,  17  in neurosurgery. The operation was
completed without charge and it wasn't long  18  Andrew was home again.
     "That surgery," Mom whispered, "was a(n)  19  miracle. I wonder how much it would have cost?" Tess
smiled. She knew exactly how much a miracle cost: one dollar and eleven cents plus the  20  of a little child.
