非谓语动词的概念
1、在句子中充当除谓语以外的句子成分的动词形式叫做非谓语动词。
2、它不受人称和数的限制
非谓语动词分为三种形式
不定式:to+动词原形
动名词:动词原形+ing
分词(过去分词)
动词不定式:
肯定式: to do
否定式: not to do
省略to的: do
基本形式及特点
用法
注意事项
(1)基本形式:
to+动词原形 (在某些情况下可以不带 to)
(2)特点 :
A.没有人称和数的变化
C . 有时态和语态的变化(被动语态的形式为 to be + 动词过去分词)
B . 可以有自己的宾语和状语
(3) 用法 :
A、作主语,如
To learn a foreign language is not easy . = It’s not easy to learn a foreign language.
注意:不定式短语作主语如果太长,常用it作形式主语,将不定式后置。除动词be外,常见的 动词有take也常用于上述结构
It took me two hours to clean my house yesterday.
B、作表语,如:
The important thing is to finish the work on time .
作宾语
C、
动词 + to do
动词 + it(形式宾语)+宾补 +to do
常用的词有: want,would like, hope , decide , prefer ,等
动词不定式和疑问词连用
We haven’t decided when to leave.
.
I find it important to learn English.
作宾补
(1)动词 + 宾语 +to do
Li Mei asked me to show her the new dictionary .
有以上结构的常用动词有tell , want , ask , order, teach, invite, wish ,help ,advise encourage 等词
(2)动词 + 宾语 + do
(不带 to 的不定式)
注:常用的动词是:感官动词see, hear, feel, watch, notice; 使役动词 have ,make,let.
作状语
A 目的状语
放在go , come , use , live, In order 等词的后面
例如: I come to visit you
He went home to ask for money.
He studies hard in order to have a good job in the future .
B 原因状语
放在sorry ,glad ,surprised ,excited 等词的后面
I’m glad to see you
I’m sorry to hear that .
C 结果状语
The room is large enough to hold 1000 people.
She is too young to go to school.
作定语
动词不定式做定语放在修饰的名词或代词之后
例如: He was the first student to go into the classroom.
I have something important to tell you.
I can do nothing to help you.
提示: 如果动词不定式和前面所修饰的词构成动宾关系,且动词是不及物动词,切记不要忘记后面的介词。
I have a small bedroom to live in
My parents have many animals to take care of .
省略to的情况:
使役动词和感官动词后:一感二听三让四看
feel/ hear, listen to/ let,make, have, /
look at, see, watch, notice
had better (not)do sth. 最好(不)做…
why not /why don’t you do sth为什么不做…
help sb.(to)do sth
Would rather宁愿做…
would you please
情态动词+do
助动词+do
在学习动词不定式的时候还有两点要注意哦!
1、在感官动词和使役动词后作宾补时,不定式可省略to,但以上词变为被动语态时,要加上to, 如
I always saw her play violin .
He was made to work 12hours a day.
2、动词不定式的否定形式为:
not + to do
Mr.Smith asked the boy ___________(not play) this kind of game.
not to play

动名词由“动词原形+ ing”构成,其与现在分词同形。动名词既有动词的性质,也有名词的性质。在句中可作主语、宾语、表语和定语。
一、作主语
1.动名词直接作主语(单个动作作主语谓语动词用单数,两个和多个动名词作主语其后谓语用复数)
Playing computer games too much /is bad for your eyes.过度地玩电脑游戏对你的眼睛有害。
Listening to English songs and watching English films/ are good ways to learn English.
考点二 动名词
2.动名词作主语时,有时可以用it做形式主语。
It is useless/ no good/ no use后习惯用动名词。
如,
It’s no use saying so much. 说这么多也没有用。
It’s no good _______(live) in this way.
注意:动名词作主语和动词不定式作主语,在很多情况下可以通用。但,动名词作主语多之一般的,抽象的或多次的行为,动词不定式作主语往往表示一次性具体的动作。
living
二、作宾语
常接动名词作宾语的单词或短语有:
动词:
enjoy, finish, consider (考虑做), miss, keep, mind(介意做), practise, suggest, avoid(避免做),imagine想象
短语:
be busy(忙于做), can’t help(情不自禁做), can’t stop(停不下做) , have fun (做某事获得快乐)
介词后加Ving:
be used to(习惯于做), be worth(做某事值得) , be afraid of(害怕做), be proud of(做某事感到骄傲), be interested in(对做某事感兴趣), keep (stop) sb from doing (阻止某人做某事), look forward to(期盼做), put off(推迟做), feel like(想要做), give up(放弃做) 等。
注意:有些词既可接不定式又可接v. ing形式作宾语,但表达的意义不同。常见的有:
(1)stop to do sth停下来去做另外一件事(不定式作目的状语)
stop doing sth停止做某事(v. ing作宾语)
(2)try to do sth 尽力(企图)做某事
try doing sth尝试着做某事
(3)forget to do sth忘记要去做某事(还没做)
forget doing sth忘记做过了某事(已做)
(4)remember to do sth记着要去做某事(还没做)
remember doing sth记得做过了某事(已做)
(5)go on to do sth做完一件事后继续做另外一件不同的事
go on doing sth继续做原来所做的同一件事
(6)need doing(某事)需要做(被动含义)
need to do 需要去做某事(主动含义)
动名词作宾的特点是正在做某事;不定式作宾是要
去做某事,强调的是即将发生。
