题型:完形填空
Towards the end of the baseball game, a controversial call was given. At full speed Paul Harvey slid home(本垒)and, thinking he had just ___36___ a game-changing run, he stood up only to face the words, “You’re ___37___!”
Angry, he threw off his helmet and ran over to explain to the ___38___ why the call was wrong. Before his ___39___ really got out of control, someone pulled him away, and he walked to the bench---___40___.
Long after the coaches, players, and fans had gone home, he realized the impact of his ___41___. Like most of us do when we are faced with the __42___ of our actions, he could have just let it go, reasoning, “Everybody ___43___ it.”
However, in the silence of his heart, he knew that just ___44___ everyone else does it, that doesn’t make it all right. And so, long after his friends had gone home, he ___45___ that coach back up to the school—not to ___46___ his car. No, the boy tracked this man down so he could tell him face to face, “I’m sorry, Sir. It was all my___47___.”
It takes true courage to stand up to face the ___48___ we all make and say, “I was wrong. I’m sorry.” What makes this ___49___ unique is that it wasn’t meant for the world to ___50___, it was meant simply as a way to stay ___51___ to his own heart.
The truth is at one time or another we have all been this boy --- ___52___ out in anger, saying hurtful things, and feeling ___53___ for doing so. But the real test comes later when we are ___54___ with the choice to say “sorry” or to walk away thinking, “Ah, they’ll get over it.”
Maybe the “they” is a customer, a friend, or a child. Whoever it is, don’t pass up the opportunity to get right with your own heart. The time for apology is now! Courage is a ___55___ of the heart.
