would have stood stoutly even if it had been almost submerge

would have stood stoutly 这里的would是虚拟语气,
had been almost submerged是过去完成时、被动语态
译文：
即使你快被淹死在水中,你还能勇敢地面对吗?

动作有先后关系
是if的虚拟语气用法

这是过去虚拟条件句

条件从句中( if if it had been almost submerged) 谓语动词用过去完成式，主语( would have stood stoutly )用“would/could/should/might+have+动词的过去分词”形式。

就算被完全淹没,也会顽强的站着.

事实上并没有被淹没,只是对过...

这个是虚拟语气，并且是对过去的虚拟，需要在主句（would have stood stoutly ）中用现在完成时，从句（even if it had been almost submerged）中用过去完成时，意思大概就是即使它几乎被淹没了，XXX也能稳固的站着。实际上并没有淹没，都没有发生，是对过去的事情的一种假设，实际是没有发生的。谢谢。...
