动词不定式的逻辑主语

Answer 1

动词不定式的逻辑主语如下：

1、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。

2、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)
