英语提问：介词后面不是只能接名词、动名词吗，下列句子怎么接的全是形容词？

Question

I was told about it in private.(private 形容词 私下的）
The motor operates well as usual．.(usual 形容词 平常的）
I noticed her eyes in particular， because they were very big．(particular形容词 特别的）
为什么介词后全是接形容词，老师说介词后面只能接名词、动名词，怎么回事啊？

Answer 1

was told about it in private.
The motor operates well as usual.
I noticed her eyes in particular, because they were very big.
这三个例句里
in private
as usual
in particular
都是副词短语， 不是形容词。
in private = privately
as usual = in the usual manner
in particular = particularly
这都是习语。

希望帮到了你。

Answer 2

介词后面跟名词做表语，宾语

介词后面跟形容词，做状语，你的例句里全是做状语的，副词性质

as usual=usually

Answer 3

介词后面不能直接跟动词,只能接名词、动名词; (是这种情况下)

Answer 4
