the strongest will may falter when the goal is to lose 50 pounds in three months or to exercise three hours a day.add failure undercuts your desire to try again.
add failure真的很怪,让人搞不清究竟动词是add 还是undercut?这是怎么回事?add是什么用法?名词还是动词啊?

Answer 1

这句话写错了,把稿件中编辑的用词窜到正文里了.正确的句子应该没有add：
The strongest will may falter when the goal is to lose 50 pounds in three months or to exercise three hours a day.Failure undercuts your desire to try again.
很容易猜出是怎么回事.初稿中没有“Failure undercuts your desire to try again”这句,编辑时小编或作者在行间用笔加了“add：Failure undercuts your desire to try again”（add是“加”,即“加一句”）,秘书打终稿的时候没想就把add也打进去了.
