When I was a law professor, a student reported that I made an error in grading his exam by giving him too many points. He was ___36___ and after thanking him for his honesty, I changed the grade in my ___37___. His beaming (欢笑的) face turned to shock. “You’re 　38 my grade?” he said angrily. “I would never have come in ___39___ ……”

He didn’t finish the ___40___, but it was obvious that his display of honesty was ___41___. He thought he’d have it all—praise and the higher grade.

Several colleagues thought I should have let the higher grade ___42___ because all I’d accomplished was to discourage him from being ___43___ in the future. And every time I tell this story, some people agree with this ___44___.

　 But I can’t see how I could give good reason for worsening my ___45___ in grading by undermining (损害) the honesty of all my grades by failing to ___46___ an error. The grade itself would be a dishonest ___47___ of his knowledge and it would have been ___48___to other students. How could I ___49___ give a student a gift of an unearned grade?

　 I know ___50___ reporting an error in one’s favor is unusual, but, like ___51___ too much change, it’s clearly the right thing to do. People of character, those with real honesty, hate to give up ___52___ as much as anyone else. The difference is that for them a good conscience and reputation is ___53___enough to give reason for the cost of doing the right thing.

　 Perhaps lowering the student’s grade did ___54___ him from being honest in the future, but bribing (贿赂) him to be honest so that he does the right thing when it’s cost-free would have ___55___him even more. The duty to be honest is about right and wrong, not risks and rewards.
