It was a mistake to see the arts as unnecessary.
句子源于2021年新高考考试全国卷2阅读理解C（完整全文见：https://www.cpsenglish.com/article/812）。
请问：as后面可以接形容词吗？
句子中的 as unnecessary 就是 as 后面接形容词吧！
网友第一应该注意搭配 see…as（把……看作或视为），这里的 as 后面可接名词、代词或动名词，有时也接形容词（可理解为其前省略了动名词being）：
It was a mistake to see the arts as unnecessary.
=It was a mistake to see the arts as unnecessary.
觉得艺术没必要的怎么看是不对的。（句首的 it 为形式主语，其后的不定式为真实主语）
