改错：With a genuine Oxford accent,she could pass as a native English speaker easily.

Question

这里的as是错的，应该改为for，答案是pass for是固定搭配，但我觉得这里的pass for,是被误认为，应该是被动语态呀，为什么是主动语态呢？我觉得应该是 could be pass for，不对吗？麻烦解释一下，谢谢

Answer 1

不对，pass for是主动语态。
导致你误解的地方是“被误认为”这个解释。

pass for的完整解释应该是“能够被误认为“，重点在”能够“上，也可以解释为”看上去像“。你看，seem不就是主动语态吗。

e.g. She looks much younger than her actual age; she could pass for a teenager even though she is already well over twenty.
