     I was telling my boy Sonny the story of the hare ( 兔子) and the tortoise ( 乌龟 ). At the end I said, " Son, remember: Be slow and steady ( 镇定的), and that will win the race. Don't you think there's

something to learn from the tortoise?"

     Sonny opened his eyes wide, " Do you mean next time when I'm entering for the 60-metre race I

should wish that Billy, Tony and Sandy would all fall asleep halfway?"

     I was shocked, "But the tortoise didn't wish that the hare would fall asleep!"

      "He must have wished that," Sonny said, "Otherwise how could he be so foolish as to race with the

hare? He knew very well the hare ran a hundred times faster than he himself did."

     "He didn't have such a wish," I insisted. "He won the race by perseverance ( 坚忍不拔的 ), by

pushing on steadily."

     Sonny thought a while. "That's a lie," he said. " He won it because he was lucky. If the hare hadn't

happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like,

or a hundred times steadier, but he'd never have won the race. That's for sure."

     I gave up. Today's children are not like what we used to be. They're just hopeless.
