逻辑主语在英语语法中的定义:
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.
逻辑主语的判断:
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)
逻辑主语就是不一定是出现在句子里的那个主语,但却是能真正发出该句子动作的人
