A well-dressed man came into a famous jeweler shop. He explained that he wished to buy a pearl (珍珠) for his wife's birthday and that the price didn't matter since business had been very good for him that year. After examining a number of beautiful and valuable pearls, he chose a nice black one that cost $ 5,000. He paid for the pearl, shook hands with the jeweler and left.

A few days later the man returned and said his wife had liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality(质地) as she wanted a pair of earrings (耳环) made. "Can you give me any advice on how to get such a pearl?" said the man. The jeweler replied,   "I would say it's nearly impossible to find an exact one like that pearl.”

The rich man asked the jeweler to advertise(登广告) in the newspapers, and offered $25,000 for the  matching pearl. Many people answered the ad(广告), but nobody had a pearl that was just right. Just when the jeweler had given up hope, a little old lady came in. To his surprise, she pulled the wonderful pearl from her handbag. "I don't like to sell it," she said sadly. "I inherited(继承) it from my mother, and my mother inherited from hers. But now I really need the money. "
