不定式成分分析(enough to和enough...to )

I've got enough propofol to put an elephant to sleep.

He has enough money to buy the whole city.

He is man enough to admit his mistake.

I don't know him well enough to ask him for help.

1.请问enough...to do和enough to do是一样的吗？这两个结构应该都算是程度状语还是结果状语？

2.在enough...to do这个结构中，to do是定语还是状语？

比如：I've got enough propofol to put an elephant to sleep.如果这句话不定式不是定语而是状语的原因是“propofol不是人不能发出动作”，那I have enough man to do the job中，man是人可以发出动作，那to do不就是定语吗？

I've got enough propofol to put an elephant to sleep. （定语）
He has enough money to buy the whole city. （定语）
He is man enough to admit his mistake. （程度或结果状语）
I don't know him well enough to ask him for help. （程度或结果状语）

1. 表示“拥有；具有” 之意的 have got 或 have，不可以使用状语修饰，所以排除不定式作状语。此外， enough 作限定词修饰名词，跟其他限定词 adequate, sufficient, plenty of, a lot of, much 等属于一种类型，enough 与这些词没有本质的区别，我们不能认定： enough 可以表示程度，这些就不可以。还有一个关键问题是，不定式的逻辑主语可以是被修饰语，不是句子主语。

2. 当 enough 修饰形容词或副词，表示达到某种程度时（man 实际用作形容词，具有形容词 manly 或 bravely 的意义；well 是副词），不定式才是程度或结果状语。
