这里low和high都是谓语动作导致宾语发生的状态的改变，术语宾补，而不是形容词作与宾语有关的状语。

形容词作状语，表示的是谓语动作发生时主语或宾语所处的伴随状态，而不是谓语动作导致的结果状态。例如：

He died young. = He was young when he died. 形容词作与主语有关的状语。

He ate the egg raw. = The egg was raw when he ate it. 形容词作与宾语有关的状语。

但你不能说：You are low when grief brings you. You will be high when prayer and faith lift you.

所以，排除形容词作状语。
