易错句子The thwarting the plan was surprisingly easy.
正确表达The thwarting of the plan was surprisingly easy.
thwarting 作名词（动名词）后接宾语时要用 of 引出，即 the thwarting of the plan；不能像动词那样直接跟宾语。
frustrate 侧重让人感到挫败、失望，常见于 be frustrated（感到沮丧）和 frustrating（令人沮丧的）这两种用法；thwarting 侧重成功阻止某人达成目标或破坏计划，宾语多为计划、企图、努力，语体更偏书面，不含“令人沮丧”这一层情绪义。
foil 与 thwart 含义最接近，都指成功挫败计划或企图，多数场合可互换；但 foil 更常出现在 foil an attempt / a plot / a plan 这类新闻和文学搭配中，动作是一次性的；thwarting 的搭配更宽，还可指持续阻挠某人，也可用于进行时表示反复阻挠。
hinder 只表示使进展变慢或增加困难，并不保证目标落空，程度比 thwarting 轻；若强调彻底阻止，让对方的目标无法实现，就应当用 thwarting。
