It would give young men a good example to follow.句子主语It不是不定式的逻辑主语,为何不定式还是用主动形式?
It would give young men a good example to follow.
it 是人称代词,指代某个事物,不是形式主语。关于不定式为什么不需要被动,不应该再是个问题了。
请按下面的思路去理解:
It would give young men a good example to follow. 等于:
It would give young men a good example for them to follow.
It would give young men a good example which they should follow.
