有关英语的:什么是逻辑主语?举例!
逻辑主语:是非谓语动词动作的执行者或承受者;它们在逻辑上存在着主谓关系或动宾关系,但不能直接作非谓语动词的主语,因此叫逻辑主语.
1. 句子主语就是非谓语动词的逻辑主语,它们之间是逻辑上的主谓关系或动宾关系.例如:
He likes helping others . (he 是helping 的逻辑主语)
Moved by his words , I told him all the news . (I 是moved 的逻辑主语)
2. 介词of 或for的宾语就是非谓语动词的逻辑主语.例如:
It's kind of you to tell me the news . (you 是to tell 的逻辑主语)
It is impossible for you to finish so much work in so short a time . (you 是to finish 的逻辑主语)
3. 复合结构中的宾语就是非谓动词的逻辑主语.例如:
The teacher asked me to answer his question . (me 是to answer 的逻辑主语)
I saw him playing at the river side . (him 是playing 的逻辑主语)

为了使整个句子看起来匀称并符合西方的表达习惯,可以用it作形式主语.
如:
It is true that he is an honest man.
that从句是真正主语. IT是形式主语.
It took them two days to get the city.
动词不定式to get the city是真正主语,IT是形式主语.

主语和谓语没有明显语法上的关系,但具有语义上的逻辑主谓关系。逻辑主语与形式主语相对应。举例:It's easy to sing Chinese songs.
it是形式主语,to sing Chinese songs是真正的逻辑主语。

逻辑主语就是句子中非谓语动词的动作发出者
比如
i have a lot of homewoek to do
中的to do的逻辑主语就是i
再如
the man talking with my father is my teacher
中talking的逻辑主语就是the man
