![2024年中考英语一轮复习-动词不定式的用法及语法功能](https://img.taocdn.com/s3/m/601ac1d485868762caaedd3383c4bb4cf7ecb791.png)
动词不定式的用法及语法功能不定式中所谓“不定”,是指不受主语的人称和数的变化的影响。
动词不定式的基本形式有两种,一种是带to的不定式,另一种是不带to的不定式。
动词不定式没有人称和数的变化,在句子中不能作谓语,但可以担任除谓语外的任何成分——主语,表语,定语,状语和宾语补足语。
动词不定式仍然保留动词的特点,即有自己的宾语和状语,也就是说,动词不定式和它的宾语或状语构成它自己的不定式短语。
不定式的语法功能不定式在句子中有各种作用,不定式具有名词,形容词和副词的特征。
不定式作名词的用法不定式在句子中的作用,有时和名词相同,在句子中担当主语,表语,宾语和宾语补足语。
不定式作主语:常用句型 It is … to …不定式作主语的句子通常用 It is … to+不定式的句型来代替,在句子中it 作形式主语,真正的主语式后面的动词不定式。
在这里,不定式被视为第三人称单数,所以动词要用 is (现在时) 或was (过去时)。
如以下例句所示:It is important to learn English well.It is dangerous to play in the street.It is hard to say goodbye with you.不定式作表语:To do 不定式作表语e.g. The best plan is to leave here. 最好的计划是离开这里。
不定式作宾语:不定式在及物动词后作宾语,常见的及物动词有:Ask, decide, begin, fail, continue, forget, hate, help, like, long, want, wait, manage, need, start, pretend, refuse, try, dare, agree, know, wish, afford 等不定式作副词的用法:不定式有时起副词作用,修饰动词或形容词,在句子中相当于状语,表示目的和原因表目的:-不定式在不及物动词后担当状语e.g. My mom came to see me yesterday evening.-针对why的疑问句回答时,如果表示目的,可用不定式来代替。

动词不定式不定式由“to+动词原形”构成,其否定形式是“ not to+动词原形”, 不定式可以带宾语或状语构成不定式短语,没有人称和数的变化,但是有时态和语态的变化。
1,不定式做主语:(1)往往放在谓语的后面,句子则用引导词it作形式主语。
It is a great pleasure to talk with him. (2)在不定式的前面加一个由for引起的断语说明不定式表示的动作的执行者。
It is easy for the students to read.(3)在下列形容词作表语时,不定式前常需加由for引起的短语,说明不定式指的是谁的情况:kind, good, nice, wise, unwise, clever, silly, wrong, right, foolish, stupid, careless, rude, polite, naught.2,不定式作宾语及复合宾语:(1)有些及物动词常用动词不定式作宾语,常见动词有:want, demand, like, hate, hope, begin, seem, fail, help, offer, manage, pretend(假装), forget, remember, promise, prepare, learn, expect, agree, determine, prefer, intend. (2)有些及物动词常用一个连接代词(副词)加上动词不定式作宾语。
常见的动词有:tell, teach, advise, show, decide, discuss等等。
The teacher taught me how to pronounce the word again and again.(3)有些动词需要复合宾语,动词不定式在复合宾语中作宾语补足语。
常见动词有:ask, advise, allow, believe, call on(号召,请求), help, know, like, order, tell, persuade, permit, want.I asked my mother to buy a new bike for me. (4)有些动词的复合宾语中,动词不定时须省掉to,这样的动词有:see, watch, notice, observe, look at, listen to, hear, have, feel, let, make, help.e.g. We wanted to have him come early.They saw the boys play volleyball on the ground after school.【注意】①help后面的 to可省掉,也可保留。
②在被动语态的句子中不定式省去的to需要还原。
Feel,hear,listento,lookat,notice,observe,se e,watch,have, let .(5)有些动词复合宾语中的不定式,常用it来表示,真正作宾语的不定式则放在宾语补足语的后面,常见的动词有:find, think, make, consider, feel.Do you consider it right to send our doctors over?3,不定式作定语:不定式作定语时,一般放在被修饰的名词或代词之后。
(1)有些名词的后面常用不定式作定语。
这些名词是:campaign(战役),courage, chance, decision, determination, drive, effort, intention(目的,意图), motive force(动力),movement, need, opportunity, right, struggle, time, way, wish. (2)有些句子常可以看到不定式作定语的用法。
这类举行常见的有:I usually have a lot of meetings to attend during the summer vacation. He has something important to tell me every day.Sorry, I don’t know you are always the first person to come here.This is not the pen to write with.I have not a friend to talk with.4,不定式作状语的用法:不定式作状语,用来修饰动词,表示目的,原因,结果,其位置和一般的状语相同。
(1)表示目的:We went to the airport to welcome the players last Saturday.【注意】有时不定式表示目的时使用in order to或 so as to加动词原形,为了表示强调,放在句首或句尾。
In order to improve my English, I read China Daily every day.He took a taxi so as to miss the train.【注意】不定式作目的状语放在句首时,其表示的目的更加明显突出,有时作为句子独立成分的插入语或习惯用语也是一样。
To tell you the truth, he has gone to Japan. To conclude, he died of cancer.To be fair, she is an honest girl.(2)表示原因:To hear him talk in that manner, you would think him a foreigner.【注意】许多形容词,副词,过去分词作表语时,后面带有不定式作状语,表示产生这种情绪的原因。
常见的这类词有:able, angry, anxious, afraid, clever, determined, eager(急于), fit, foolish, free, glad, lucky, cruel,delighted(高兴的), pleased, ready, sorry, sure, willing, happy, shocked(震惊), proud, frightened, fortunate, surprised, disappointed, careful.e.g. You are sure to succeed.The students are anxious to learn a second foreign language.Be careful not to catch cold.(3)下面结构中的形容词后面可带不定式,句子的主语可以是人,也可以是物。
这样的形容词有:easy, hard, difficult, comfortable, deep, good. e.g. The new leader is easy to get along with. The river is broad, deep and good to swim in. 5,不定式的时态形式:动词不定式一般有三种时态形式,即一般式,进行式,完成式。
(1)一般式(to do):表示的动作通常与主要谓语动词所表示的动作(状态)同事(或几乎同时)发生,或之后发生。
I hope to see you again.(2)完成式(to have done):表示的动作,先于句子的谓语动词所表示的动作或状态。
I’m glad to have met your parents here.I’m sorry to have kept him waiting for me so long.(3)进行式(to be doing):表示不定式的动作正在进行,与句子的谓语动作同时发生,其中不定式的动词应是延续性动词。
When he came in, I happened to be reading on the bed.He pretended to be doing his homework when he heard his father’s voice.6,不定式的被动式:当不定式的逻辑主语是不定式所表示的动作的承受者时,不定式一般用被动形式。
不定式的被动形式有两种:一般式 to be done; 完成式 to have been done.e.g. It is an honor for me to be asked to speak here.7,不定式被省略时应注意的问题:当一个不定式被省略时,下列情况一般要保留to,表示省略的是一个不定式。
(1)—Would you go there with me?—I’m glad to.(2)—Did you pass the exam?—No, I tried to, but failed.(3)—Do you want to sing them an English song? —I prefer not to.(4)You had better sing an English song if they ask you to again.这种用法的结构还有:used to(常常), be going to(打算), mean to(打算), ought to(应该), plan to(计划), want to(要想).8,…but…句型中的不定式符号to省略与保留:I have no choice but to go there alone.I have nothing to do but go there alone.He did nothing but cry all day long.【注意】句子中but后面的不定式带不带to,取决于but前面的句子里含不含do,只要有与do(did)有关的词(do作谓语, to do作定语等)but后面的不定式就省掉to.。
