高中英语非谓语动词讲解及练习

编辑: 逍遥路 关键词: 高中英语 来源: 高中学习网


非谓语动词是指分词(包括现在分词和过去分词)、不定式、动名词等三种形式,即:

doing , done , to do , doing 。当然它们有各自不同的变化形式,如:

现在分词 doing : 有being done(被动式) ; having done (完成式); having been do

ne (完成被动式)

不定式 to do : 有to be done (被动式); to have done (完成式); to be doing(进行式)

动名词 doing : 有having done(完成式); being done(被动式) ;

非谓语动词的特点: 三种非谓语动词都具有动词的特征,虽然它们没有人称和数的变化,但是它们都能带自己的状语或有时跟宾语。它们都有各自的特征:分词具有形容词和副词的特征;动名词具有名词的特征;不定式具有名词、形容词和副词的特征。具体来讲:分词在句子中可以做定语、表语、状语或补足语等;动名词在句子中可以做主语、宾语、表语等;不定式在句子中可以做主语、宾语、表语、补足语或状语。

下面分别对三种非谓语动词进行讲解:

一.动词不定式

先看几个例句,判断不定式在句中的成分。

1.To learn a foreign language is difficult .

2. His wish is to be a driver .

3.Tom wanted to have a cup of beer .

4.The teacher told us to do morning exercises .

5.I have nothing to say .

6.They went to see their aunt .

7.It’s easy to see their aunt.

8.I don’t know what to do next .

9.I heard them make a noise .

说明:1.动词不定式作主语, 2.动词不定式作表语,3.动词不定式作宾语,4.动词不定式作宾语补足语,5.动词不定式作定语,6.动词不定式作目的状语,7.动词不定式作真正主语,it 代替动词不定式,作形式主语。8.带有连接代词的动词不定式作宾语,9.不带to 的动词不定式作宾语补足语。

掌握动词不定式应注意的几个问题:

1. “to” 是不定式符号还是介词,下列短语中的to 都是介词。

agree to object to close to , come to , lead to , refer to ,

equal to , familiar to , point to , thank to , devote to , next to , belong to , be used to , look forward to

2. 带to 还是不带to

I have no choice but to give in

I cannot do anything but give in

I saw him enter the classroom .

( 但是: He was seen to enter the classroom .)

3. 动词不定式逻辑主语是由for 作为标记的。但是有时用of .

It’s necessary for you to study hard .

It’s foolish of him to do it .

与of 连用的形容词有:

good, kind , nice , wise ,clever , foolish , right , wrong , careful , careless , polite , possible

4.后接不定式作宾语的动词有:

want , hope , wish , like , begin , try , need , forget , agree , know , promise , teach , refuse , help , arrange , dare , decide , determine , fail , manage , offer , prepare , continue , ask , mean , choose , expect etc.

需要宾语补足语的动词不能用动词不定式直接做介词的宾语,而要用it做形式宾语。例如:通常不说We think to obey the laws is important . 而说We think it important to obey the laws .

5.不定式的省略。下列短语中,如果意义明确,常常省略到to 。

want to , wish to ,hope to , like to , hate to , plan to , try to , love to , have to , o

ught to , need to , used to , be able to

6.不定式作定语,应注意两种关系:

1)动宾关系:

He has a lot of meeting to attend .

Please lend me something to write with .

He is looking for a room to live

He is looking for a room to live in .

He has no money and no place

to live ( in ) .

I think the best way to travel ( by ) is on foot .

There is no time to think ( about ) .

2)主谓关系:

She is always the last ( person) to speak at the meeting .

----I’m going to the post office , for I have a letter to post . ( 逻辑主语是I )

-------Thank you. But I have no letters to be posted now ( 逻辑主语不是I )

7.不定式作状语,可以有以下几种意义:

1) 原因

He is lucky to get here on time .

这种结构中常用的形容词有:

happy , glad , delighted , pleased , sorry , eager , anxious . lucky , fortunate , proud , angry surprised , frightened , disappointed , ready , clever , foolish , worthy

2) 目的

He came to help me with my maths .

3) 结果

I hurried to get there only to find him out .

The book is too hard for the boy to read .

He is old enough to go to school .

8 . 不定式作补足语

I saw him play in the street just now .

能跟不带to 的不定式作补足语的动词有:

see , feel , hear , listen to , look at , watch , let , have make, observe, notice

注: 当这些词为被动式时,不定式要带to , 如:

He was seen to play in the street just now.
