1、高中英语动词不定式 不定式知识点综述 2、不定式重难点讲解 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”构成（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、完成式、完成进行式四种时态变化形式，一般式和完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 完成式to have done to have been done 完 成 进 行式to have been writing 不定式知识

2、点综述1.不定式的基本形式to do,to be done to be doing;to have done,to have been done 2.否定式构成1.不定式词作主语句型2.识记用不定式作宾语的动词3.跟动名词作宾语区别1.省略 to 的不定式作宾语补足语动词“五看三使两听一感”2.不定式作目的、结果状语a.不定式的时态是以句中谓语动词的时间为依据的：（1）一般式表示的动作或状态通常发生在谓语动词之后或同时发 生。例：They made plans to live in Paris.他们计划住在巴黎。（to live 发生在 made plans 之后）（2）进行式表示其动作正在进

3、行，与谓语动词发生的动作同时进行。例：He pretended to be listening to me carefully.他假装认真地听我讲。（3）不定式的完成式所表示的动作或状态发生在谓语动词所表示的动作之前。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 所表示的时间之前）（4）不定式的完成进行式表示动作在谓语动词之前发生，而且一直进行着。例：He was happy to have been staying with his uncle.他很高兴一直跟他叔叔住在一起。b.不定式

4、的语态不定式的时态是以逻辑主语为依据的：例：The sports meeting on the weekend has to be put off.周末的运动会被迫推迟。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”结构中，有时尽管主语是动作的承受者，不定式在意义上是被动，形式上却是主动，这时可以看成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
