be unaware of后面加什么

be unaware of后可以接名词、动名词以及what、how、where等引导的从句。因为of是介词。意思是“不知道”“没有意识到”。例如：

I was unaware of his existence until now.现在我才知道有他这麽个人。

He was unaware of his mistakes.他没有意识到自己的错误。

You seem to be unaware of how urgent thesituation is.  你好像没有意识到形势是多么的急迫。

可以用not know或者not realize来替换 分析：be unaware of，意思是“不知道没意识到”

I was unaware of was that she had breast cancer. 我那时不知道的是她得了乳腺癌。 可以替换成：What I didn't know was that she had breast cancer. may be unaware of his rudeness. 他有可能没意识到他的粗鲁。

He may not realize his rudeness.
