`An eight-year-old child heard her parents talking about her little brother. All she knew was that he was very sick and they had no money. Only a very expensive operation could save him now and there was no one to lend them the money.When she heard her daddy say to her tearful mother, “Only a miracle can save him now,” the little girl went to her bedroom and pulled her money from its hiding place and counted it carefully.She hurried to a drugstore (药店) with the money in her hand.“And what do you want?” asked the salesman. “It’s for my little brother,” the girl answered. “He’s really, really sick and I want to buy a miracle.” “Pardon?” said the salesman.“My brother Andrew has something bad growing in side his head and my daddy says only a miracle can save him. So how much does a miracle cost?” “We don’t sell a miracle here, child. I’m sorry,” the salesman said with a smile.“Listen, if it isn’t enough, I can try and get some more. Just tell me how much it costs.”A well-dressed man heard it and asked, “What kind of a miracle does your brother need?”“I don’t know,” she answered with her eyes full of tears. “He’s really sick and mum says he needs an opera tion. But my daddy can’t pay for it, so I have brought all my money.”“How much do you have?” asked the man. “$ 1.11, but I can try and get some more,” she answered.“Well, what luck,” smiled the man. “$ 1.11, the price of a miracle for little brothers.”He took up the girl’s hand and said, “Take me to where you live.
