非谓语动词的省略现象广泛存在于英语语境中，掌握这一知识点对于理解和运用英语语法有着重要的作用。
本文将对高中英语中非谓语动词的省略现象进行归纳和总结。
一、不定式的省略不定式是非谓语动词的一种形式，通常由“to + 动词原形”构成。
在以下情况中，不定式可以被省略：1. 当不定式的逻辑主语与句子的主语一致时，可以将不定式省略。
例：Jack plans to go swimming this afternoon, and I plan to (go swimming) too.2. 当句子主语与不定式所表达的动作的执行者一致时，可省略不定式的主动式。
例：He asked me to help, but I refused to (help).3. 当两个不定式所表示的动作相同，并且前一个不定式中含有动词“let”时，可以省略后一个不定式。
例：He let us stay at his house, or just go.4. 当句子主语与不定式所表达的动作的承受者一致时，可省略不定式的被动式。
例：He made me (be) his assistant, which was a great honor.二、动名词的省略动名词是以动词的-ing形式构成的名词，在某些情况下可以省略。
以下是一些常见的动名词省略的情况：1. 当动名词作主语时，可以省略动名词。
例：Smoking is harmful to health.→(To) smoke is harmful to health.2. 当动名词作宾语时，可以省略动名词。
例：I enjoy s wimming in summer. →I enjoy (swimming) in summer.3. 当动名词作表语时，可以省略动名词。
动词不定式省略to的9种情况
不定式省略to的九种情况一、使役动词后省略to的情况在let, make， have等使役动词后用作宾语补足语的不定式必须省略to。
如：My mother wouldn't let me go to the film。
我妈妈不会让我去看电影的。
I don't like milk， but mother made me drink it。
我不喜欢牛奶，可是母亲强迫我喝。
I would have him wait for me at the gate of the park。
我要他在公园门口等我。
注意：1. 当使役动词用于被动语态时,要补上在主动语态中省略的to（主要是指make，let和have很少用于被动语态)。
2。
force， oblige等虽然也表示2。
force， oblige“使”,但它们后用作宾语补足语的不定式必须带to。
如：He forced me to go with them。
他迫使我同他们一起去.The police obliged him to leave. 警方强迫他离开.二、感觉动词后省略to的情况在感觉动词后用作宾语补足语的不定式必须省略to.如：I watched her get into the car. 我看着她上了车。
I saw the woman enter a bank. 我看见这个女人进了一家银行.We often hear her sing this song. 我们经常听到她唱这首歌。
Did you notice her leave the house? 她离开屋子你注意到了吗？注意:1. 这里所说的感觉动词主要包括see, hear， observe, notice， feel， watch等。
但是它们用于被动语态时,其后的不定式必须带to。
如：The woman was seen to enter a bank。
有人看见这个女人进了一家银行。
高中英语里动词不定式的几种常见省略形式.doc
高中英语里动词不定式的几种常见省略形式非谓语动词历来是高考中的重点，不定式结构在考点中常占很大比重。
用法也很复杂，现就动词不定式to 的几种常见的省略形式作如下小结。
1．感官动词和使役动词在主动语态中不需要带to，即我们常说的“一觉二听三让五看”：feel,listen to 、hear ,let、make、have, see、watch、notice、observe、look at.The teacher has us keep a diary every day.老师要我们每天写一篇日记。

注意：除let 外其他在变成被动语态时要加上to。
The lady was seen to enter the hotel by us .我们看见那个女人进了那家酒店。
2由all，what 引导的主语从句或者主语被only, first, one, least 或形容词最高级修饰时，而且从句中含有do时，其表语如果是动词不定式，则往往省去to。

谈谈不定式的省略
为了避免重复，省略句子中的一个或几个成分，这种语法现象称为省略。
不定式的省略一般有三种常见形式：省略动词原形而保留符号to 、省略不定式符号to和省略整个带to不定式。
一、省略动词原形而保留符号to
动词原形的省略是指前面出现过的动词在下文再次出现时，可以单纯使用不定式符号to 即：只省去动词，而保留符号“to ”。
如：
. Don’t stop unless you have to (stop ).
Y ou may bring the dictionary with you if you want to (bring it ).
---Will you go with me ?
---Well, I’d like to ( go with you ).
---Have you ever been to the seaside ?
---No, we can’t afford to ( go to the seaside).
就不定式在句中的所起不同作用这一角度来看，在语言意义十分清楚和语境非常明确的情况下，动词原形在以下几种情况下省略：
1．动词不定式在care, want, hope, wish , expect, prefer, refuse, mean, try , promise, like , love（尤其在would like, would love, want等之后）等动词后作宾语时，常常可以省略动词原形。
如：
----Are you interested in going to university ?
----Y es, I would like to( go to university ).
2. 动词不定式在ask, warn, tell , advise, force, wish, expect, allow, permit 等动词后作宾语补足语或主语补足语时，常常可以省略动词原形。
如：
D on’t touch anything unless your teacher tells you to( touch them ).
As it is very hot, she wants to go swimming in the lake, but her mother doesn’t allow her to( go swimming ).
3. 动词不定式在happy, glad, eager, anxious, willing, ready等形容词后作状语时，动词原形可以省略。
95年NMET 第30题就是这种类型。
如：
---Will you join us in the game ?
---Thank you. I’d be happy to (join in the game).
4. 动词不定式在与be able to, be going to, have to, ought to, used to , mean to , try to, plan to等构成复合谓语时，不定式结构可以省略动词原形。
97年NMET 第22题就是个例子。
如：
We don’t go skating in winter as we used to (skate ).
---Do I have to go with them to swim ?
---Y ou do n’t have to (go ) if you have something important to do.
二、省略不定式符号to
1. 在语言意义十分清楚和语境非常明确的情况下，为避免重复，常出现不定式符号to 被省略的情况, 98年NMET第10 题就是一例。
值得注意的是，like 和want 之后在一般情况下，to是不能省略的，但在从句中（如在when, if, as 之后），to 常常省略。
如：---Try to b e back by 12 o’clock, will you ?
---Ok, I’ll try( to ).
---Shall I go to play ?
---If you like (to ) , you can go now.
2 .当两个或多个带to 的不定式由并列连词and 或or 连接在一起时，第二个（及其后的）不定式符号常省略。
如：
I want him to write these sentences down and (to ) translate them into Chinese.
I asked the students to read over this article carefully and( to ) write down the important points or ( to )put forward questions if there are any.
但：当两个或多个带to 的不定式并列使用时，若有对比关系，那么每个前面就得加to。
如：
He hasn’t decided whether to go home or to stay at school during the vacation.
To try and fail is better than not to try at all .
三、省略整个带to不定式
在语句结构相对独立、语意非常清楚的情况下，整个带to的不定式可以省略。
如：----Would you go with me this evening ?
----Sorry, I don’t have time ( to go ).
She should attend the English party, but she was shy ( to do so ) .。
