什么是不定式的逻辑主语,英语
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.
不定式并不像现在分词或过去分词那样表示明显的主动或被动关系,它的逻辑主语只能根据句子的意思去慢慢体会找出.
不定式用主动结构表被动的形式总结如下:
1) sb have sth to do (不定式的动词所表动作由主语完成)
如:I have many flowers to water.(我给花浇水)
2) sb/sth be adj to do (介词).(不定式所表动作的宾语是该句的主语)
如:English is diffilult to learn.
She is hard to work with.
3) There be sth to do(但也可使用to be done)
如:There is still a lot of work to do.
4) with sb/sth to do sth(不定式所表动作当时尚未发生,但不管不定式所含动词与宾语sb/sth是主动/被动关系,一律使用主动结构 to do sth)
如:With a lot of work to do,I can't go out to play with you now.
再如:With you to help me,I can finish the work easily.
(当然该句只是用来和上句对比说明该动作并未发生,它并不是不定式主动表被动用法)
