林肯当上总统后,经常给他的部下讲这样一个故事: 小时候,他与哥哥一起耕地,那牛怎么也走不快。兄弟俩正为此发愁时,那牛忽然飞快的奔跑起来,把兄弟俩累得满头大汗。到了地边,林肯问:这是怎么回事?哥指着牛背上一只马蝇说:全靠了它。林肯不忍,一巴掌将马蝇拍死。那牛没了马蝇的叮咬,便复归原样,懒惰而不肯卖力。 When Lincoln became the president, he often told his subordinates a story: When he was a child, he cultivated land with his brother. How did the cow go unpleasant? When the brothers were worried about it, the cow suddenly ran wildly, sweating the two brothers tiredly. To the ground, Lincoln asked: What is going on? Brother pointing to a horse on the back of a horse, said: rely on it. Lincoln could not bear slap the horse fly killed. The cow did not bite the horse flies, they return to the original, lazy and unwilling to work hard.
