     A mother camel was walking with her son through the desert. They were looking for water and grass.

     The son asked his mother what water and grass looked like. The mother replied that water was blue and looked like

the sky, while grass was green and nice.

     After they had walked a day and a night, her son suddenly cried,"Look,Mother, there's water and grass over there."

     "What a foolish talk,my child!"

     The water and grass was on the left, while the desert was on the fight. Because the mother camel had been blind in

her left eye since she was a baby, she could see nothing with her left eye. After they had gone another day and night,

the young camel found a second oasis(绿洲), but his mother still did not believe him. She said that was not all oasis,

but a desert. She said she knew more than her son and couldn't be wrong.

     Her son got angry. When he saw an oasis again, he left his mother without telling her. He ran into the grass and ate

his fill(吃个够).
