如果某人说的话非常正确,可以用英语表达为"She hit the nail on the head."这个短语的来源可以追溯到古英语时期,当时用钉子去固定木板时,会用一个小木棍来敲打钉子,以使钉子更牢固地钉在木板上。这个小木棍叫做"nail",而如果敲得正确,就会把钉子敲到木板的正中间,此时就可以用"hit the nail on the head"来形容这个动作。

例句:

She hit the nail on the head when she said that the company needed to focus more on customer service.(她在谈到公司需要更多关注客户服务时,说得非常正确。)
His analysis of the situation hit the nail on the head.(他对这种情况的分析非常正确。)
