非谓语动词的用法

请高手举例说明一下非谓语动词（不定式、动名词、分词）的用法，即在什么情况下使用那种形式？在哪些情况下三种或二种形式都可以用？

Answer 1

简御液单的给你梳理一下吧！
不定式一般用在两个动词连接的时候，还有一种就是充当主语的时候。
如：I want to go to see the film. ( to go 和to see 都是不定游梁式）
To finish my homework alone is really hard for me.（To finish 也是不定式，做主语）
然后呢，动名词，也可用在两个动词连接的时候，也可以充当主语，还可以用作形容词，最后就是用作名词了。
如：I want to go to swim. 可以说成 I want to go swimming.
Finishing my homework alone is really hard for me. （道理同上）
This is an interesting book. （interesting 用作形容词）
I love swimming.
最后哦，动词分词（神拆运你说的应该是过去分词，因为动名词我们也可以叫做动词的现在分词，注意区别哦），过去分词可以用在（现在/过去）完成时，用于被动语态，还有就是用作形容词。
如：I have bought the book.
I had bought the book.
She is / was asked to do the job.
Oh, I am / was so excited.
自己慢慢的归类一下吧，希望能够帮到你的！

顺口溜：本领最多不定式，主表定补宾和状；样样成分都能干，只有谓语它不敢；大家千万要小心，有时它把句型改；作主语时用it，自己在后把身藏；七个感官三使役，宾补要把to甩开；疑问词后接上它，宾语从句可充当；逻辑主语不定式，不定式前加for sb.；to前not是否定，各种用法区别开。
以下是不带to的动词不定式(即动词原形)的常见用法
★ let sb. do sth让某人做某事 ★ make do sth使得某人做某事
★ hear do sth do sth听见某人做某事 ★see do sth do sth看见某人做某事
★ why not 或why don’t you +动词原形？为什么不….?（表示建议）例:Why not/Why don’t you take a walk?
★ 某人+had better( not)do 某人最好(不)做某事
★ 情态动词can/may /must /should+ 动词原形（包括情态动词的否定形式+动词原形）
★ 助动词do/does/did/will/would在构成疑问句或者构成否定句即don’t /doesn’t /didn’t /will not /would not+ 动词原形
★ be going to + 动词原形（表示“即将”“打算” 做某事）
