句首的不定式做什么成分

To think she wanted to walk all the way to the park.

①这个句子里的不定式做什么成分?

②这个句子是一个独立的句子吗,还是只是一个宾从?

还有这个句子,总感觉句子机构很奇怪:

To spend so much money on something he didn't even need.

还有这个句子,不知道不定式在这里是不是做状语,做什么状语(原因状语?

He was very willing for everyone else to come.

1. 动词不定式放在句首,可以表示条件。若是如此,网友的句子则不完整。

不定式有时放在句首用来表示条件,其产生的结果往往带有虚拟或主观推断的性质,因此句中常用 should, would, could 等情态动词。

To look at him, you could hardly help laughing. 假如看他一眼,你就会禁不住大笑起来。

To hear him talk, you would think he owned the whole world. 如果听他说话,你会以为他拥有整个世界呢。

2. 不定式短语可以是感叹句。

不定式短语单独使用,常表示惊异、气愤、祝愿等情绪。

To sell such a cheap suit as that to a millionaire 竟然把这样一套衣服卖给一位百万富翁!

To think that I shall never see her again! 真没想到我再也见不到她了!

To think of my leaving the umbrella in the train! 真没想到我把伞落到火车上了!

网友的句子属于第二种情况,不定式引导感叹句。句末应改为叹号。

To think she wanted to walk all the way to the park!

真想不到,她想要一路走着去公园!

To spend so much money on something he didn't even need!

他竟然花那么多钱买他根本不需要的东西!

3. He was very willing for everyone else to come.

for everyone else to come 为不定式复合结构,作willing 的补充性状语。否则,句意不完整:He was very willing.(?)
