And even the like precurse of fierce events,
As harbingers preceding still the fates
And prologue to the omen coming on,
Have heaven and earth together demonstrated
Unto our climatures and countrymen.
这是一个宾语前置的句子。句子主语为 heaven and earth together,谓语动词为现在完成时 have demonstrated,由于宾语前置,助动词have倒装于主语之前。(这种倒装不是必须的,而是选择性的。)even the like precurse of fierce events为前置的宾语,其中precurse为名词 (古体),其后的as介词短语为precurse的非限制性定语。as 意为"作为"。unto=to, 介词短语作状语修饰谓语动词,表示demostrated的对象。
