专题14 动词不定式在中考语法项目中，主要考查动词不定式作宾语、宾语补足语、目的状语。
动词不定式由“to+动词原形” 构成，有时to省略，直接由动词原形构成。
否定式由“not to+动词原形”构成。
如：We decided to go on hiking though we were tired. 虽然我们很累，但是我们决定继续远足。
The girl tried not to wake up her mother. 这女孩尽量不吵醒她妈妈。
1. 动词不定式作宾语（1）接不定式作宾语的动词（“动词+to do” 结构）常见的有：learn 学会plan 计划decide 决定try 尽力choose 选择agree 同意refuse 拒绝pretend 假装offer 主动would like / want 想要expect 期望hope / wish 希望promise 承诺afford 负担得起prefer 喜欢help 帮助(help to do / help do) like 喜欢(like to do / doing)continue 继续(continue to do / doing)begin / start 开始(begin / start to do / doing)如：I would like to have a sandwich. 我想要吃一个三明治。
（2）动词不定式作宾语，置句末，前面用it指代不定式，it是形式宾语。
如：We found it difficult to understand what you said. 我们发现很难理解你所说的话。
（3）有的动词在不定式前可加上疑问词（who，what，which等）作宾语（即“动词+疑问词+to do” 结构），常见的有：show 表明、指示；know 知道；tell 告诉；teach 教；learn 学习；decide 决定。
八年级英语动词不定式+双宾语讲解及练习
八年级英语动词不定式+双宾语讲解及练习专题三：动词不定式+双宾语一．动词不定式含义当我们要表示“想做某事、需要做某事或决定做某事”时，就会出现两个动词连用的情况，这时应如何表达呢?同学们自然会想到want to do sth。
need to do sth.和decide to do sth.等表达方式。
行为动词后的动词都采用了“to+动词原形”的结构。
我们把这种结构称为动词不定式。
动词不定式没有人称和数的变化，在句中不能作谓语。
二．动词不定式的功能1.动词不定式作宾语(1)动词+to do sth.表示的多为将来的行为。
如：want to do sth。
/ hope to do sth。
/ learn to do sth。
/ try to do sth。
/ decide to do sth。
/ forget to doXXX to do sth。
/ stop to do sth./ plan to do sth.等(2)to偶然可省略，布局为动词+do sth.had better do sth。
/ why not do sth.2.动词不定式作宾语补足语(1)宾语补足语是对宾语的补充说明，结构：“动词+宾语+动词不定式”。
其否定结构要在todo前面加not,构成not to do。
如：allow sb。
to do sth。
/ choose sb。
to do sth。
/ want sb。
to do sth。
/ tell sb。
to do sth。
/ ask sb。
to doXXX(2)在表示感觉、祈使等意义的动词help。
make。
let。
have。
feel。
see等后接不带to的不定式。
3.动词不定式作目的状语(1)假如透露表现“做某事是为了甚么”，能够用动词不定式透露表现目标，常与soas，in order等组成短语不定式既可以放在句首，也可以放在句尾。
如:XXX to have rest.=To have rest。

动词不定式复习语法复习：动词不定式动词不定式（to do)是初中英语课的一个重点,也是中考要考查的一个项目.动词不定式属于非谓语动词的一种形式，很多同学经常把它和谓语动词混在一起，掌握起来有困难。
下面我们对动词不定式的用法做简单归纳，帮助同学们记忆:一、动词不定式在句子中不能充当谓语,没有人称和数的变化。
二、动词不定式是由“to+动词原形”构成(有时可以不带to）.动词不定式的否定形式是“not+动词不定式"(not不与助动词连用）.三、动词不定式短语具有名词、形容词和副词等的功能,可在句中用做多种句子成分。
1、主语:常置于句末,而用it代替其做形式主语。
To go in for sports helps you stay fit.It is dangerous to swim in the deep sea on your own.注：此句式中不定式逻辑上的主语可由for或of引出，逻辑主语由of引出时,表语的形容词为kind，nice, good, polite, clever, foolish，right, wrong等表示评价的形容词.例：It’s right of him to refuse the invitation。
(him为逻辑主语)2、表语：Our duty is to protect the environment。
3、动词宾语:此种情况可按固定搭配或句式去记。
例：Would you like to see my photos？Kevin planned to visit his uncle。
和plan用法一样的词还有：start, want，agree，hope, begin，decide等。
I found it very difficult to get a job。
（it为形式宾语)4、宾语补足语：(1) 在多数复合宾语及物动词后要带to。
例：I asked a friend to read it to me. (book4，L2)（2）在表示感觉、致使等意义的动词(see，watch, hear, feel，notice, observe，make，let，have, help等) 后不带to。
例：They heard him sing a pop song in the meeting room。
5、定语：动词不定式做定语放在所修饰的名词的后面。
例：I have something important to say。
6、形容词补足语:在表示心理、感情、评价等的形容词后,对其进行补充说明。
例：We are very glad to meet you again。
7、状语：表示目的、原因、程度等。
例:They brought in photos of their families for me to look at.8、“疑问词+不定式”用法：不定式前可带what, who，which, where，when, how等疑问词，这种不定式短语在句中多用做宾语。
例：He didn’t tell me where to go。
