Tess was a little girl. Her brother was very sick. But her family didn't have money to send him to the hospital. "Only a miracle(奇迹)can save him now,"said her dad.
Tess got out all the money she had saved. Then she walked a long way to the pharmacy(药店)."What do you want?"the pharmacist asked.
"Well, my brother is sick," Tess answered. "My daddy says only a miracle can save him. So how much is a miracle?"
"We don't sell miracles here. I'm sorry but I can't help you,"the pharmacist said.
"I have the money to pay. Just tell me how much it costs."
A well﹣dressed man was standing nearby. He asked the little girl:"What kind of a miracle does your brother need?"
"He needs an operation. But my daddy can't pay for it."Tess replied with tears in her eyes.
"How much do you have?" asked the man.
"One dollar and 11cents," Tess answered.
"Well,"smiled the man."A dollar and 11cents﹣that's just the price of a miracle for your little brother."
He took her money and said:"Take me to your home. I want to see your brother. Maybe I have the kind of miracle you need."
That man was a famous doctor. He gave the boy the operation for free. Before long, the boy was home again and doing well.
"That operation," her mom said to her dad quietly, "was a real miracle. I wonder how much it would have cost."
Tess smiled. She knew exactly how much a miracle cost…one dollar and 11cents…and the love and faith(信心)of a little child.
