　　One day, a poor boy named Howard Kelly was trying to pay his way through school by selling goods door to door．He was hungry, so he decided to beg something to eat．

　　When a young woman opened the door, instead of a meal he asked for a drink of water．Thinking he looked hungry she brought him a large glass of milk．He drank it and then asked, “How much do I owe you?”

　　“No, you don’t owe me anything,” she replied．“Mother has taught me never to accept pay for a kindness．” Leaving that house, he not only felt stronger physically, but it also increased his faith in God and the human race．He was about to give up before this point．

　　Years later the young woman became seriously ill．The local doctors couldn’t cure her illness．They sent her to the big city, where specialists could be called in to study her disease．Dr．Howard Kelly, now famous, came for the consultation(會(huì)診)．When he heard the name of the town where she came from, a strange light filled his eyes．Immediately, he went into her room．

　　Dressed in his doctor’s gown he went in to see her．He recognized her at once．He went back to the consultation room and determined to do his best to ________．From that day on, he gave special attention to her case．

　　Finally, the battle was won．Dr．Kelly asked a nurse to send the bill to her room．She was afraid to open it because she knew that it would take the rest of her life to pay it off．Finally she looked and read these words on the side of the bill：“Paid in full with a glass of milk．”(Signed)Dr．Howard Kelly．

　　Tears of joy flooded her eyes as she prayed silently：“Thank you, God．Your love has spread through human hearts and hands．”
