阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

In old times, there was a story about a young athletic boy hungry for success, for whom winning was everything.

One day, the boy was preparing himself for a running competition in his small native village. He and two other young boys were to compete. A large crowd had gathered to witness the competition and a wise old man, upon hearing of the little boy, had travelled far to bear witness also.

The race started. Sure enough, the boy dug deep and showed his determination, strength and power. He came first. The crowd cheered and waved at the boy. The wise man remained still and calm. The little boy, however, felt proud and important.

A second race was called, and two new young challengers came forward to run with the little boy. The little boy finished first once again. The crowd again cheered and waved at the boy. The wise man expressed no opinion.

“Another race, another race!” shouted the little boy. The wise old man stepped forward and presented the little boy with two new challengers, a frail (虚弱的) old lady and a blind man. “What is this?” asked the little boy. “Race!” said the wise man. The race was started and the boy was the only finisher. The little boy raised his arms in delight. The crowd, however, was silent showing no happiness. “Why don’t they join in my success?” he asked the wise old man. “Race again,” replied the wise man. “This time, all three of you, finish together,” continued the wise man. The little boy thought a little, stood in the middle of the blind man and the frail old lady, and then took the two challengers by the hand.

The race began and the little boy walked slowly, ever so slowly, to the finishing line and crossed it. The crowd cheered and waved at the boy. The wise man smiled.
