高中英语不定式语法
非谓语动词在高中英语中，非谓语动词包括动词不定式(to do)、动名词(－ing)、现在分词(－ing)与过去分词(－ed)三种形式，它们有不少共同特点：①在句子中不能充当谓语，不受主语人称和数的限制；②保留部分动词特性：可以后接宾语，可用副词修饰；③否定形式，都是在其前面加上not/never等否定词；④表示的动作，如果明显发生的谓语动词表示的动作之前（或者强调先后），要求用完成时态形式;⑤都不能作地点状语，只有动词不定式可以作目的状语；⑥没有主语，其表示动作的执行者叫作“逻辑性主语”（主动语态时），有时表示动作的承受者（被动语态时）非谓语动词可充当句子的很多成分，并且有时态和语态的变化如下：Ⅰ动词不定式定义：动词不定式是非谓语动词的一种，它没有人称和单复数的变化，在句子中不能独立作谓语，但它仍保持动词的特点，可以有自己的宾语和状语。
一、不定式的时态和语态：1. 动词不定式的时态1). 一般式：当不定式表示的动作或状态发生几乎同时或晚于谓语动词表示的动作或状态时用一般式；eg. ①He seemed to be tired.②The building to be finished next month is for our teachers.2). 进行式：当不定式表示的动作或状态与谓语正好同时发生时，用进行式。
eg. ①When I went to his home, he happened to be traveling around the world.②I didn`t expect you to be working in such bad conditions.3). 完成式：当不定式所表示的动作或状态明显发生在谓语动词之前，用完成式；eg. ①He is said to have written a novel about the Long March.②He is said to have been taught French when he was a child.4). 完成进行式：如果不定式表示的动作发生在谓语动词之前，强调一直在进行或有可能继续进行，用完成进行式.eg. ①We are happy to have been working with the experts all the month.②I suspected him to have been playing instead of studying.5. 不定式的语态：1）当不定式的逻辑主语是其表示的动作的执行者时，一般要用主动式；eg. ①The workers are to build the great bridge.当不定式的逻辑主语正好是其表示的动作的承受者时，一般要用被动式(to be done).eg. ①The great bridge is to be built by the workers.2) 若是明显发生在谓语动作之前，而且含有被动含义，就用完成被动式( to have been done).eg. ①He is said to have written a novel about the Long March.②He is said to have been taught French when he was a child.二、不定式的功能：1. 不定式做主语：不定式做主语一般表示具体的某一次动作，而动名词doing 表示习惯的，经常的动作。

动词不定式不定式知识点综述不定式知识点综述1.不定式的基本形式 1. 不定式词作主语句型 1. 省略 to 的不定式作宾to do, to be done 2. 识记用不定式作宾语语补足语动词“五看to be doing; to have done, 的动词三使两听一感”to have been done 3. 跟动名词作宾语差别 2. 不定式作目的、结果2. 否认式组成状语2、不定式重难点解说重难点 1：动词不定式的时态语态动词不定式 (infinitive) 两种形式：一种是“to + 动词原形”组成（ to- infinitive ）；另一种是不带 to 的不定式 ,即动词原形 (bare- infinitive) 。
动词不定式有一般式、进行式、达成式、完成进行式四种时态变化形式，一般式和达成式有被动语态变化形式。
主动语态被动语态一般式to do to be done进行式to be doing达成式to have done to have been done达成进行式to have been writinga. 不定式的时态是以句中谓语动词的时间为依照的：（1）一般式表示的动作或状态往常发生在谓语动词以后或同时发生。
例：They made plans to live in Paris.他们计划住在巴黎。
（to live发生在made plans以后）（ 2）进行式表示其动作正在进行，与谓语动词发生的动作同时进行。
例： He pretended to be listening to me carefully.他假装仔细地听我讲。
（3）不定式的达成式所表示的动作或状态发生在谓语动词所表示的动作以前。
例： I am sorry to have kept you waiting.对不起，让你久等了。
（to have kept 发生在 I am sorry 所表示的时间以前）（4）不定式的达成进行式表示动作在谓语动词以前发生，并且向来进行着。
例： He was happy to have been staying with his uncle. 他很快乐向来跟他叔叔住在一起。
b.不定式的语态不定式的时态是以逻辑主语为依照的：例： The sports meeting on the weekend has to be put off.周末的运动会被迫推延。
注意：意义上被动形式上主动的不定式在“名词（代词）＋ be easy(difficult, fit 等形容词 ) ＋不定式”构造中，有时只管主语是动作的蒙受者，不定式在乎义上是被动，形式上倒是主动，这时能够当作省略了动词逻辑主语for us, for me , for you 等。
例： The book is difficult to read.这本书很难读懂。
i. 不定式作主语1. 不定式作主语和表语口语中常用it 作形式主语。
2. 若说明不定式动作关于履行者的影响，常在不定式前加for sb.。
3. 可是以形容词作表语来说明主语的行为质量时（如 kind ，goodnice，wise，clever ，silly ，wrong9 right,foolish, stupid, careless, considerate, rude, naughty, polite, agreeable 等），不定式前加of sb.。
4.不定式作表语，表示目的、结果、赞同、命令、安排、决定、劝说等意义。
