倒装句?为什么?Also included will be any variations that have arisen from volcanic activity,solar activity,and,possibly,human activities.该句为倒装句?正确语序为"any variations that...will be included"?为什么可以倒装?只听说否定词 only so 等等提前可以倒装……

这里需要倒装
理由：如果不倒装句子就成了
Any variations that have arisen from volcanic activity, solar activity, and possibly,possibly, human activities will be included.其实这个句子也是正确的，但是你会发现主语any variationsthat have arisen from volcanic activity, solar activity, and possibly,possibly, human activities 很长，后面的谓语和宾语部分很短，通常在英语中为了避免这种头重脚轻我们才将表语提前倒装成了这种形式。
其实倒装还有其他的情况，不止你提到的这些。

祝学习进步，望采纳。
