8 阅读理解。 I was telling my boy Sonny the story of the hare and the tortoise. At the end I said, "Son, remember: Slow and steady wins the race. Don"t you think there"s something to learn from the tortoise?" He opened his eyes wide. "Do you mean next time when I"m entering the 60-metre race I should wish Billy and Tony and Sandy would all fall asleep halfway?" I was surprised. "But the tortoise didn"t wish the hare would fall asleep." "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(毅力), by pushing on steadily." Sonny thought for a while. "That"s a lie," he said. "He won the race 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." 1. The writer argued with his son because _______.
