区分 guilt charge blame accusation 这四个词各自是用在什么场合?

1 B.which to be based upon
we need to have factual knowledge __________ our thinking.
我们需要基于我们想法的实际知识,也就是表达“实际知识基于我们的想法”
这个含义,可以用
which（指代factual knowledge） is based on our thinking.
or
which to be based on our thinking.
二者等价.
2 C.So clever are the construction robots
So...that句型,so在前主谓倒装,所以are在robots前,一般倒装不用such...that.
3 D.having been canceled
由于后面的一句是主语,所以All flights__________ because of the storm只可能是一个短语,这里应该是被动语态,“被取消”,所以是having been canceled.
区分 guilt charge blame accusation
guilt 负罪感,用于某人做了错事之后感到良心不安
charge,accusation 二者均为指控,一般表达为 charge...with,accuse of例如：
在警察局他被正式控告犯谋杀罪.
At the police station,he was formally charged with murder.
他被指控为不称职.
He was accused of incompetence.
blame 责备,一般是小错误,如:
The driver was not to blame for the accident.
这次事故怪不着司机.
