The dog take any sudden movements as threatening.
as 接形容词不知道对不对
通常接名词比较常见
如果是固定句型
I take him as generous. 我认为他很慷慨/是慷慨的人
可以这样造句吗?

为什么我觉得这边的as应该用for比较恰当？

有人知道回一下吗 > <

只查到take sth as sth的用法。第一句我会改成The dogconsiders any sudden movements (as) threatening第二句不知你想表达的是什么? I consider him (as)generous.还是I treat him generously.

I consider him as a serious man的意思吧

原想抛砖引玉的，忍不住还是想野人献曝一下。这边其实就是“视A为B”的用法：take A for B＝think of A as B＝look upon A as B＝consider A (to be) B......等等理论上as、for等介系词后应接动名词，但是实际上直接加形容词也屡见不鲜。或许这也可以充分解释为何“把...视为理所当然”的词组"take sth. for granted"中的for后面是直接加granted这样的过去分词吧？

可以用take A as B,B是形容词或名词。类似用法如楼上consider/regard/think of/look on A as B而take A for granted翻做“把A视为理所当然”Y
