"be unaware of" 是英语中常用的形容词短语,意为“没意识到;不知道;未察觉”,强调主语对某件事缺乏认知或注意。
作为表语形容词短语,"be unaware of" 需与be动词(am/is/are/was/were等)搭配使用,后接不同类型的宾语(名词、代词、动名词或从句),具体结构如下:
直接接“事物/人”的名称或代词,说明“没意识到某事物/某人”。
I was completely unaware of the change in the meeting time.(我完全没意识到会议时间改了。)
They are unaware of the danger ahead.(他们没意识到前方的危险。)
She’s unaware of him—he’s been standing there for 10 minutes.(她没注意到他——他已经站在那儿10分钟了。)
of是介词,若宾语是“动作”,需用动词的-ing形式(动名词),表示“没意识到正在做/被做的事”。
He was unaware of being watched by the camera.(他没察觉自己正被摄像头监视。)
We’re unaware of having made such a big mistake.(我们没意识到犯了这么大的错误。)
若要表达“没意识到某个事实/情况”,可直接接that引导的宾语从句(此时省略of)。
She seemed unaware that everyone was laughing at her.(她似乎没意识到大家在笑她。)
I’m unaware that the project has been canceled.(我没意识到项目已经取消了。)
程度修饰:可加副词(如completely/totally/utterly)加强语气,表示“完全没意识到”。
例:He was totally unaware of the tension in the room.(他完全没察觉到房间里的紧张气氛。)
反义词:"be aware of"(意识到;知道),二者对比记忆更清晰:
I’m aware of the rules.(我知道规则。)
I’m unaware of the rules.(我不知道规则。)
"unaware" 是表语形容词,不能单独作谓语,必须与be动词搭配(不能说He unaware of...,需说He is unaware of...)。
of后面不能接动词原形(错误:She was unaware of go → 正确:She was unaware of going)。
通过以上用法和例子,相信你能轻松掌握"be unaware of"的实际应用啦!
