● 动词不定式的用法总结
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。例:
To go in for sports helps you
stay fit.(book4,L28)
It helps you stay fit to go in for sports. 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 invitation1.(him为逻辑主语)
2、表语:Our duty is to protect the enviroment.
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.(book4,L11)
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:Vinny is the first disabled2 person to sail3 around the world.(book4,L1)
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:Weareverygladtomeetyouagain.
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.(book4,L2)
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.
9、在初中阶段还涉及到“不定式被动语态一般式(tobe+过去分词)”。
例:There are twenty more trees to be planted.

关于初中英语语法之动词不定式的形式的用法介绍
初中英语语法大全:动词不定式的形式
对于英语的学习中,关于动词不定式的形式知识点的内容,我们做下面的讲解学习哦。
动词不定式的形式
1.作主语。 如:
To learn English is very important.
但实际上不定式作主语常用 it来作形式主语,而将不定式移至谓语动词后作真正的主语。
如上句可表达为:
It's very important to learn English.
2.作表语。 如:
My idea is to ring him up at once.
3.作宾语。 如:
I have decided to go to Binjiang Primary School.
4.作宾语补足语。
a. ask, want, teach, tell, know , would like, allow等动词后面接动词不定式作宾语补足语。
如: The policemen asked him to get off the bus.
b. hear, see, look at, feel, watch, notice, listen to等动词后接不带to的动词不定式作宾语补足语。
如: We often see Miss Li clean the classroom.
c. let, make, have这些使役动词后接不带to的动词不定式作宾语补足语。但在被动语态中这些不带to的都须带上to。
如: In those days the bosses often made the workers work day and night.
d.动词help接动词不定式作宾语补足语,可带to也可不带to。
如: Can you help me (to) carry the heavy bag?
5.作定语。
a.与被修饰词有动宾关系。如:I have something important to tell you.但如果不定式动词为不及物动词,后面的介词千万不要省略。
如: Maybe they have three rooms to live in.
b.与被修饰词有主谓关系。
如: Mr Liang is always the first to come and the last to leave.
c.与被修饰之间只有修饰关系。
如: I have no time to play cards.
6.作状语,表示目的、原因、方法、方向、结果等。
如: I'll go to meet my friend at the railway station.
7.不定式复合结构"for sb. to do sth" 作主语时,常用"It is +adj+ for
of sb. to do sth"的句式。形容词good, bad, polite, unkind, kind, ice, clever,
right, wrong, careful等用"It is +adj +of sb. to do sth."
其他形容词用 for。
如:
It's dangerous for you to ride so fast.
It's very kind of you to help me.
8.动词不定式与疑问句who, what, which, when, how, where, whether等连用。
如: I don't know when to start.
He didn't tell me where to go.
但上面结构相当于一个从句,故上述句子也可表达为:
I don't know when we'll start.
He didn't tell me where he would go.
注意:
a.有些动词或动词短语不能带不定式,只能接动词的-ing形式。
如: enjoy, finish, keep, mind, miss(错过),be busy, go on, keep on, be worth, practise等。
如: The peasants are busy picking apples.
Would you mind my opening the door?
b.有些动词后可接不定式,也可接动词的-ing形式,但意思不同。
如: Lu Jian forgot to post the letter.(该寄但还没做)
Lu Jian forgot posting the letter.(已经寄过信了)
They stopped to sing a song.(停止在做的工作而去做另一件工作)
They stopped singing.(停止正在做的工作)

解读动词不定式作主语、宾语、定语、状语
在中学教科书中,动词不定式是一个非常重要的语法点;在历年高考中,动词不定式是频频考查的要点之一;在学生的学习实践中,动词不定式是琐碎、难学的语法项目之一。为了更熟练、准确、有针对性地掌握此项语法知识,下面把(N)MET对动词不定式作主语、宾语、定语及状语的考查点进行总结、归纳。
I. 不定式作主语
1. 不定式作主语时,常用it作形式主语,而将作主语的不定式放在句子后部。例如:
It is good to help others.帮助他人是件好事。
It is exciting to surf the Internet.上网是件令人兴奋的事。
2. 不定式作主语与V-ing形式作主语的不同:前者作主语时,常表示某一次具体的动作;而后者常表示习惯性的动作。例如:
To teach the three children is my job this afternoon. 教这三个孩子是今天下午我的工作。
Walking is a good form of exercise. 散步是锻炼的一种好方式。
简析: It's ... of sb. to do sth.与It's... for sb. to do sth.
当表语形容词说明不定式的逻辑主语具有某种品质时,常用"It's...of sb. to do sth."。例如:
It's very kind / nice of you to help me。感谢你的帮助。
当表语形容词说明不定式具有某种特征时,应使用 "It's ...for sb. to do sth."。例如:
It's hard for the Chinese students to learn Russian. 中国学生学俄语是很难的。
[高考题例]
1. Is ________ necessary to complete the design before National Day?
A. this B. that C. it D. he
2. It was foolish ________ you to give up what you rightly owned.
A. for B. of C. about D. from
II. 不定式作宾语
1. 学习不定式作宾语时,要注意掌握四种动词:
1) 后接不定式作宾语的动词。常见动词有: offer, decide, hope, promise, agree, plan, manage, refuse, wish, pretend, learn, want等。
2) 后接V-ing形式作宾语的动词。常见动词有: enjoy, mind, suggest, advise, finish, practise, imagine, admit, avoid, delay等。
3)后接不定式和V-ing形式作宾语均可,且没有大的区别的动词。常见动词有: start, begin, continue等。
4)后接不定式和V-ing形式作宾语均可,但意思不同的动词。常见动词及短语有:try, remember, forget, regret, stop, go on等。例如:
Please remember to lock the door when you go out. 出去时请记住要锁门。
I don't remember lending you any money. 我不记得借过钱给你。
I regret saying what I said. I shouldn't have said it. 我后悔我所说过的话,我本不该说那些话。
I regret to tell you that you failed your driving test. 我很遗憾地告诉你,你没有通过驾驶测试。
The minister went on talking for two hours. 部长的讲话持续了两个小时。
After discussing the economy, the minister then went on to talk about foreign policy. 讨论完经济,部长接着谈论外交政策。
2. 动词不定式在句中作宾语,如带有宾语补足语时,要先用it作形式宾语,而将该不定式后置。例如:
I don't think it right to do it in that way.我觉得以那种方式去做是不恰当的。
I find it hard to get along with him. 我发现与他相处不是件容易的事。
3. "疑问代词、疑问副词 + 不定式"常常用作动词或介词的宾语。例如:
I don't know where to spend my holiday. 我不知该去哪儿度假。
Have you decided when to marry?你决定什么时候结婚了吗?

不带to的动词不定式做宾语补足语构成let sb /sth do sth结构,这类动词有feel感觉,hear听到,see看见,watch观察,notice注意到,make 迫使,have让
在某些固定词组或短语后面要跟不带to的不定式,如:had better 最好,would
rather 宁愿 ,would rather...than...宁愿。。。。。。也不。。。。。。,

有些动词后要只跟动名词作宾语,如:enjoy享受。。。。。。的乐趣,finish完成,mind 介意 allow允许feel like 想要 等
