each one of us后面用is还是are

后面用is，例如：

1.Each one of us is here to learn lessons.我们所有人都应该吸取教训。

2.Each one of us is pooping and peeing something that could fertilize half or maybe all of our food, depending on our diet.我们每个人都产生能够肥沃我们一半甚至全部食物的排泄物，具体取决于我们的食谱。

3.I have no hesitation in saying that each one of us is as intimately attached to the soil of this beautiful country as are the famous jacaranda trees of Pretoria and the mimosa trees of the bushveld.我可以毫不犹疑地说，我们每一个人都跟这美丽祖国的大地亲密地牢不可分，就如红木树之于比勒陀利亚，含羞草之于灌木林。
