初中动词不定式专题讲解及练习(全面)

语法：动词不定式

动词不定动式是一种非谓语动词形式，

它没有人称和数的变化，在句子中不能作谓语

，但

可以作除谓语之外的其它任何句子成分（主语、表语、宾语、宾语补足语、定语和状语）；动词不定式具有名词、形容词和副词的特征，同时还保持动词的某些特点，既可以有自己的宾语和状语，动词不定式和它的宾语和状语构成不定式短语。

一、二、

构成：to do .否定式not to do 常见时态：一般时

to do 进行时to be doing

完成式to have done

完成进行式to have been doing

三、动词不定式在句子中的成分

1、作句子的主语：现实中常用it作形式主语，而把真正的主语动词不定式（或短语）后置。比较下列句子

To learn from your friends is important.=It is important to learn from your friends . To leave without saying goodbye is impolite.= It is impolite to leave without saying goodbye.

To chat with Miss White is a pleasant thing.=It is a pleasant thing to chat with Miss White.

To walk to school takes me ten minutes.=It takes me ten minutes to walk to school. 句型总结

It is + adj. + of sb. to do

特征等的形容词（如对，错等等）。

It is very kind of you to help me.

It’s not polite of him to speak to old people like that. It is + adj. + for sb. to do

动作是谁做的，则在不定式前加一个

…≠are +adj. +to do sb. is

如果要说明不定式表示的…

for引起的短语，即不定式的逻辑主语。

sb. is…= are +adj. +to do

在以某些表示人的品质、…

kind、good、nice、wrong、clever、right等）作表语时，不定式之前

常加一个引起的短语，说明不定式指的是谁的情况（可以理解为某人的好，坏，聪明，愚蠢，

It is necessary for us to study hard.It is easy for him to speak English.

’s suggestion is to take more exercise.

注意1：动词不定式作宾语时如带有宾语补足语，则要把不定式放在后面，用

it作形

式主语，构成“主语+动词+it+宾补（形容词、名词）+不定式”结构

注意2：常用带to的动词不定式作宾语补足语的动词有

want, ask, tell, order, get,

）、

三让（make, let, have）、四看（look at, see, watch, notice, observe）、半帮助help（可
