    Once there was a piano player in a bar (酒吧). People came just to hear him play. But one night, a lady

asked him to sing a song.

    "I don't sing," said the man.

     But the lady told the waiter,"I'm tired of listening to the piano. I want the player to sing!"

     The waiter shouted across the room, "Hey, friend! If you want to get paid, sing a song!"

     So he did. He had never sung in public before. Now he was singing for the very first time! Nobody had

ever heard the song Mona Lisa sung so beautifully!

     He had talent (天赋) he was sitting on! He may have lived the rest of his life as a no-name piano player

in a no-name bar. But once he found, by accident, that he could sing well, he went on working hard and

became one of the best-known singers in the US. His name was Nat King Cole.
