 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: Slow and steady (稳固的) wins 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 participating in the 60-metre race I should wish that Billy and Tony and Sandy would all fall asleep halfway?”

I was shocked, “But the tortoise didn’t wish that the hare would fall asleep on the way!”

“He must have wished that,” Sonny said. “Otherwise how could he be so stupid 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 , 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.

61.Sonny believed that the tortoise ________.

won the race by his own effort

B. took a risk by agreeing to race

C. was not given a fair chance in the race

62.Billy, Tony and Sandy must be ________.

A. boys who were unknown to Sonny’s father

B. boys Sonny had run races with before

63.The writer thinks that his generation (代) ________.

A. were more clever than Sonny’s generation
