     Richard Gray was a famous explorer (勘探者). He was also a

millionaire. He had visited every country in the world. He had

crossed Antarctica, flown across the Atlantic by balloon, and

climbed Mount Everest. Last year he decided to walk across Death

Valley, the hottest place on Earth. He walked for days over the hot

desert sand. One night he found the camp (宿营地) where he had

been the night before. Cray had walked in a circle. He was lost.

     Two days later he had drunk all his water.  He couldn't walk.

He crawled to the top of a sand dune (沙丘) , and there he saw a

man. The man was wearing smart, clean trousers, a white shirt

and a tie. Gray crawled over to him.

     " Water...water..." he said.

     " I'm terribly sorry ,  old boy , " replied the man, " but I haven't

got any water with me. "

      " Help me ! " shouted  Gray , " I'm a rich  man...a  millionaire...

I'll give you anything. "

      "That's very nice of you, old boy," said the man, " Look,I

can't give you any water, but would you like to buy my tie?"

       "A tie?  Of course not ! " screamed Gray, and crawled away.

He crawled slowly up the next sand dune. His mouth was full of

sand. His lips were cracked(破裂) and dry. He couldn't breathe.

He reached the top of the dune and there he saw a huge good

hotel.Girls were swimming in the large swimming pool. Beautiful

fountains were all around the hotel.

       "Is it a mirage(幻景) ?" he thought," Am I dying?" He stood

up and staggered(蹒跚) down the dune.

      A waiter in a shining white uniform came out of the door.

       " Water...water...a bath !  Food ! " screamed Gray.

      "I'm sorry, you can't come into this hotel,"said the waiter.

       " Why not?  I've got plenty of money...I'm a millionaire. "

       " Ah, " replied the waiter, " but you aren't wearing a tie ! "
