2 know sb to be 能省略 to 吗

看了前面一个关于 know 的用法的解答,受益匪浅!

虽然有点复杂,我会慢慢体会,真心感谢专家老师!

这里还有一个关于 know 的问题。像下面这样的句子,其中的 to 可以省略吗?

I know him to be honest.

I knew him to be honest.

I have known him to be honest.

I never him to be honest.

I have never known him to be honest.

know sb/sth to do结构通常用于被动结构。例如:

He is known to be a good doctor.

这种结构用来表示大多数人认为某种情况是真的。即上句中他是个好医生是大多数人的看法。因此不能用“我”作主语的主动结构中,这是对该句型的误用。

I know him to be a good doctor. (误)

但在否定结构中,not/never know sb (to) do sth, 这个结构表示主语的经历,翻译为: 从没有见过/经历过某人为某种情况。此时不定式带to或不带to均可。例如:

 I’ve never known her (to) make a joke. 我从没见过她开玩笑。

因此,网友的如下句子:

I know him to be honest. (错。应改为被动句:He is known to be honest.)

I knew him to be honest. (同上)

I have known him to be honest. (同上)

I never knew him to be honest. (正确。to可以省略)

I have never known him to be honest. (正确。to可以省略)我从没见过他诚实的时候。

    to be 作 know 的宾语补足语时,to 不能省略。例如:

    1. I know him to be ill. (正确,但是更常说:I know he's ill.) (摘自《薄冰英语用法问答1144例》pp.1060-1061)

    2. I have never known him to be dishonest. (动词 know 即使使用完成时态,其后的不定式 to be 亦不可省去 to ) (摘自《薄冰英语用法问答1144例》p.516)
