阅读下面的文章，按要求回答问题高贵的施与汽车大王福特不是一个吝啬的人，但他却很少捐款。他顽固地认为，金钱的价值并不在于多寡，而在于使用方法。他最担心的就是捐款经常会落到不善于运用它们的人手里。有，一次，佐治亚州的马沙贝蒂校长为了扩建学校来请求福特捐款，福特拒绝了她。她就说：“那么就请捐给我一袋花生种子吧。”于是福特买了一袋花生种子送给了她。没想到一年以后，贝蒂女士又上门了，交给了他600美元。原来学生们播种了当初的那袋子花生种子，这就是一年的收获。福特什么都没说，立即拿出了600万美元交给了贝蒂。我赞赏福特的顽固，他的顽固中有一种对受施者的老辣调教。福特的担心绝不是多余的，太轻易得来的金钱往往很难让受施者感受到金钱后面潜藏着的苦与智；我更赞赏贝蒂对点滴施与的至高的尊重，她带领孩子们撒播下的其实是足以证明他们有能力领受他人恩惠的资格。彼此的信任，为“慷慨”培植了一个甚慰心怀的伟大理由。我们时常赞美慷慨无私的捐助，尤其在意捐助数额的大小，以为一个数目所昭示的正是与这个数目等值等量的一颗爱心。我们很少见到捐助者与受助者相得益彰的完美辉映，更何谈双方心灵的深切契合。其实，善意是不能标价的，恩惠也不必承载过多的酬酢。贝蒂校长对于捐助的完美阐释与福特对施与的精辟理解达到了心灵的契合和高度的信任。
