well enough和good enough的区别是用法不同，适用场合不同。well enough比较正式，并且作副词。good enough 比较随意，并且一般用作形容词。

例句：It would be a matter of assessing whether she was well enough to travel.问题是要看她是否已康复到可以旅行。It's not good enough just to blame the unruly children.对难管教的孩子只是责备是不够的。I never had a long-term relationship as I wasn't good enough, or interesting or amenable enough.因为我不够优秀，不够有趣或者不够亲切，所以恋爱关系从来都维持不长。
