     Years ago, there lived a wealthy man named Mr. Cooper who, with his dearest young son John, loved art

collecting. Together they traveled around the world, collecting the finest art treasures.

     One winter, war came to the nation, and John left to serve his country. After only a few short weeks, his

father received a telegram reading that John had died while saving a fellow soldier. Filled with sadness, the old

man cried. On the coming Christmas morning, a soldier called on him and gave him a picture of John.

     The following spring, the old man became ill and passed away. According to his will, all of his works of

art would be auctioned (拍卖) on Christmas Day, when he had received the greatest gift of his life. The day

soon arrived and art collectors from around the world gathered to buy some of the world's greatest paintings.

The auction began with a painting of the old man's son. "Who will open the bidding (出价) with $100?" the

auctioneer (拍卖人) asked. Minutes passed, but no one spoke. Finally, a neighbor of the old man's spoke.

"Can I take the painting for ten dollars? It is all I have, and he is a good man."

     "Will anyone go higher?"called the auctioneer. After more silence, the auctioneer said, "Going once, going

twice, gone." The gavel (槌) fell. "Now we can get on to the real treasures," someone shouted angrily. But the

auctioneer said that the auction was over. Someone asked,"It's over? We didn't come here for a picture of

some old guy's son. There are millions of dollars worth of art here!"The auctioneer replied, "It's very simple.

According to the will of the father, whoever takes the son...gets all."
