1、省略
?? 1)感官动词 see, watch, observe, notice, look at, hear, listen to, smell, taste, feel 等
　 I saw him work in the garden yesterday.
　昨天我看见他在花园里干活了。(强调"我看见了"这个事实)
　 I saw him working in the garden yesterday.
　昨天我见他正在花园里干活。（强调“我见他正干活”这个动作）

2) 使役动词?? have , bid , make , let 等词后不定式要省略,但同感官动词一样，被动以后要还原to
?? I have my package weighed.
? Paul doesn’t have to be made to learn.
3) 动词help?? help sb do??? help sb to do??? help to do2、有些动词后只跟不定式：
want，wish，hope，manage，promise，refuse，pretend，plan， offer，decide，agree，expect?? allow sb to do,? cause sb to do , permit sb to do, enable sb to do ，force sb to do，be more likely to do?， love to do，? warn sb to do、be?? ambitious to do、 start to do
3、有时候to后面要接-ing形式：
accustom (oneself) to; be accustomed to; face up to; in addition to; look forward to; object to; be reduced to; resign oneself to; be resigned to; resort to; sink to; be used to; be alternative to; be close/closeness to; be dedication/dedicated to; be opposition/opposed to; be similarity/similar to.
4、need/want 后的-ing具有被动意思。(want不太常用)
???He needs (a lot of) encouraging.? 5、不定式的独立主格结构 不定式具有它自己的独立主语时，二者即构成不定式独立结构，常用作伴随的状语和主语。
eg. I to bear this is some burden.
6、“for + 名词（代词）+不定式” 结构
for的复合结构，它在句中可用作主语、表语、宾语、定语、状语等。
eg. For a child to do that job is just inconceivable.
7、“疑问词+不定式”结构
who, what , which , where , how等构成的短语，在句中可用作主语、宾语、表语等。
运用动名词时的注意点：
1、有些词后只能接动名词
admit; appreciate; avoid; celebrate; consider; contemplate; defer; delay; deny; detest; discontinue; dislike; dispute; enjoy; it entails; escape; excuse; explain; fancy; feel like; finish; forgive; can't help; hinder; imagine; it involves; keep;? it means; mention; mind; miss; it necessitates; pardon; postpone; practice; prevent; recall; report; resent; resist; risk; suggest; understand...
2、一些动词接-ing形式的常用说法：
it's no good; it's no/little/hardly any/ use; it's not/hardly/scarcely use; it's worthwhile; spend money/time; there's no; there's no point in; there's nothing worse than; what's the use/point...? 3、有些词后加不定式和动名词均可；但remember, forget, try, stop, go on, cease, mean后面用不定式和-ing形式，意义截然不同。
I remembered to post the letters. (指未来/过去未来的动作)
I remembered posting/having posting the letters (我记得这个动作)
4、prefer的用法：
我宁愿在这里等。
I prefer to wait here. （所以啊，你不介意的话，我就等下去。）
I prefer waiting here.（我正在这里等，我就喜欢这么做。）
I prefer swimming to cycling. （这个句子里面就不能用不定式了。）?
????? 运用分词时的注意点：
1、现在分词表示主动进行:
1)一般式:???? Do you see the man talking to the dean? ?(与谓语动词同步发生)
2)完成形式：Not having made adequate preparations, they failed. (发生谓语动词之前)
? 3)完成被动形式：Having been adapted, the script seems perfect.( 发生谓语动词之前且表示被动)
2、过去分词表示被动：
1）Fight no battle unprepared.
?2) 过去分词的进行形式：You'll find the topic being discussed everywhere. (强调正在被做)
???这三种非谓语动词，都可以构成复合结构，非谓语动词所修饰的成分是这些非谓语动词的逻辑主语。他们之间的一致关系——主动还是被动，往往就是考点。独立主格结构中，要注意的是分词与他前面的逻辑主语之间的主动被动的关系。?
