非谓语动词的三种形式

非谓语动词的三种形式
非谓语动词的三种形式

非谓语动词共分为三种,构成形式如下:

1.动词不定式(Infinitives):

2.现在分词和过去分词(present participles & past participles):

3. 动名词(gerunds)

下面我们依据句子的成分,来具体分析非谓语动词的不同用法。

1.非谓语动词做主语和表语

主语、表语和同位语在句子中用名词来担当,非谓语动词中动词不定式和动名词均可以用作名词,因此,动词不定式和动名词可以用来担当这三种成分。

1)非谓语动词做主语

一般情况下,用动名词来做主语的情况比较多,动词不定式用作主语的情况比较少。通常来说,在表达将来的要发生的事情时用不定式来作主语,而表达一般情况习惯性的动作时用动名词来作主语。

例如:Teaching is a tiring but satisfying job.

Swimming is a good kind of exercise.

To be an astronaut is Johnson’s desire.

在用it做形式主语的句子中通常用动词不定式来做真正的主语。

例如:It is necessary (for you) to give up smoking.

It is everyone’s duty to protect the environment.

但是值得注意的是在各别情况下,即使是It做形式主语,真正的主语也必须用动名词,这些情况很少,所以希望同学们能单独记忆下来,以下是此类情况的一个总结。

It is/was no use/good doing sth.

It is/was not any use/good doing sth.

It is/was of little use/good doing sth.

2)非谓语动词做表语

非谓语动词作此成分的时候跟作主语时的规则基本一致。

在表示“目的,愿望,梦想,需求”等名词做主语时其表语应该用不定式.

例如:Her wish was to become an artist.她的愿望是成为一位艺术家Our aim is to help them,not to teach them a lesson.我们的目的是帮助他们,而不是教训他们。

动名词做表语,表示抽象概念。动名词做表语一般用来表示“身份,职业”等.大部分时候主语与表语可以互换。

例如:My job is teaching.(Teaching is my job.)

此外,还要注意主语与表语的一致性。

例如:Seeing is believing.百闻不如一见。

To see is to believe.

刚才我们说了动名词和动词不定式做表语时的区别。现在我们来看一下,除了动名词和动词不定式以外还有没有其他的非谓语动词可以做表语,还剩下一种非谓语动词,就是动词的过去分词,那么它能不能用来做表语呢,答案是肯定的,那么下面我们就要讲一讲动名词做表语和动词过去分词做表语有什么区别。

这一讲我们称之为分词做表语,因为我们知道动名词又称为动词的现在分词形式。

3)分词做表语

首先做一些练习

1.The situation is____(encourage).

2.The door remained____(lock)when he came again.

surprise,interest,excite,puzzle,disappoint,astonish,encourage,inspire,shock,move 等及物动词用做表语时,要看其与主语的关系。如果与主语为主动关系,则用-ing形式,表示主语的特征。如果是被动关系,用-done 这种形式,表示主语的状态。

The news astonished us.这句话就表明了the news与astonish为主动关系。astonish与us为被动关系。那么就可以直接得出以下两个句子:

1)The news was astonishing.

2)We were astonished(by the news).

练习:

3.She looked_____(disappoint).

4.The news is quite___(astonish).

练习:

选择最佳答案:

1.The speech was so _____that they were all____.

A.inspiring;exciting

B.inspiring;excited

C.inspired;excite

D.inspired;exciting

2.Her wish is ___an engineer.

A.becoming

B.become

C.to become

D.being come

3.Some people's greatest pleasure is______.

A.fishing

B.to fish

C.to be fishing

D.being fish

4.--“You look pale.”

--“I feel a little______.”

A.tire

B.tired

C.tiring

D.tiresome

5.As we joined the big crowd I got_____________ from my friends.

A.separated

B.spared

C.lost

D.missed

2.非谓语动词作宾语

动词不定式和动名词也可以用来担当宾语,但并非随意使用。某些担当谓语的及物动词后只使用不定式的各种形式,某些及物动词后则只使用动名词的各种形式,而还有某些及物动词后要根据不同情况,分别使用不定式或动名词来担当宾语。由此可见,分清谓语动词自身基本用法中对宾语的不同要求是十分必要的。

1).跟不定式担当宾语的及物动词

afford买得起, agree同意, arrange安排, ask要求, attempt企图, care专心, claim宣称, dare敢于, decide决定, demand要求, desire渴望, determine决意, expect期待, fail没干成,

help帮助, hope希望, intend打算, learn学会, manage设法干成, mean本意想, need需要, offer 主动, plan计划, pretend假装, promise承诺, refuse拒绝, want想, wish盼望

* 跟不定式担当表语的不及物动词seem似乎, appear显露出,happen碰巧。

2).跟现在分词当宾语的及物动词

考虑建议盼原谅,

承认推迟没得想.

避免错过继续练,

否认完成就欣赏.

禁止想象才冒险,

不禁介意准逃亡.

consider,suggest/advise,look forward to,excuse/pardon

admit,delay/put off,fancy

avoid,miss,keep/keep on,practise

deny,finish,enjoy/appreciate

forbid,imagine,risk

can't help,mind,allow/permit,escape

至此,我们就大致上讲完了非谓语动词作主语、表语及宾语的情况,下面给大家总结一下。

主语:只有现在分词和动词不定式可以做主语。

表语:现在分词、过去分词和动词不定式都可以做表语。

宾语: 现在分词和动词不定式可以做宾语。具体情况要根据前面的谓语动词的搭配来决定。

初中英语非谓语动词详解

非谓语动词 非谓语动词指的是在句中起名词,形容词或副词作用的动词形式,而不是作谓语的动词形式。动词的非谓语形式分为动名词,分词,动词不定式。 Climbing mountain is a good exercise. (Climbing..., 动名词起名词作用) Do you know the man wearing a white shirt. (wearing ..分词起形容词作用) He gets up early to catch the first bus. (to catch ...不定式起副词作用) 谓语动词和非谓语动词的区别: 1)谓语动词在句中可单独作谓语,而非谓语动词不能单独作谓语。 Miss Mary teaches us English. 玛丽教我们英语。(teaches 动词作谓语) Mr. Li came to our classroom to have a talk with us last week. (to have a talk.... 不定式作状语) 2)谓语动词受主语的人称和数的限制,而非谓语动词形式没有这种限制。 Mike likes the pop music. (动词用单数第三人称形式) Lucy has nothing to do today。(do 用原形) 非谓语动词的形式变化: 不定式主动被动 一般to write to be written 进行to be writing 完成to have written to have been written 完成进行to have been writing 现在分词主动被动 一般writing being written 完成having written having been written 过去分词主动被动 一般written 动名词主动被动 一般writing being written 完成having written having been written ●动词不定式: 动词不定式是由to + 动词原形构成,在句中起名词,形容词和副词的作用,可以担任除谓语以外的其它任何成分。(主语,宾语,宾语补足语,表语,定语,状语) 1. 动词不定式作主语: To master a language is not an easy thing. To teach English is my favorite. It's my pleasure to help you. 动词不定式作主语时可以放在后面,而用it 作形式主语放在原主语的位置上。 It's very kind of you to have given us much help. 你给了我们那么多的帮助真是太好了。 It's necessary to find the witness. 有必要找到目击者。 2. 动词不定式作宾语: 某些及物动词可以用动词不定式作宾语,这些动词有decide, begin, help, begin, want, wish, like, forget, learn, ask. What I wish is to learn English well.

非谓语动词非谓语形式(详细)

动词非谓语形式 一.基本概念: 顾名思义,不担任谓语成分而担任其他语法功能的动词称为非谓语动词,有to do (动词不定式) / -ing (现在分词 / 动名词) / -ed (过去分词)三个形式。由于他们不受主语人称和数的限制,故也称为"非限定动词"。(学习中不要刻意去区分现在分词和动名词) 二.非谓语动词的时态和语态意义: 英语中动词有两大基本特征:时态和语态的变化。非谓语动词也是动词,当然也具备动词的这两大特征。 1. 时态概念:非谓语动词只有"过去、现在和将来"三个时间概念,他与谓语动词时态的区别是:谓语动词表示的是实际时间概念,如I am learning English.是指讲话的时候或那段时间里"我正在学英语"。而非谓语动词的"过去、现在和将来"是指相对于谓语动词而言的"过去、现在和将来",即先于谓语动词的行为或状态称为"过去时",与谓语动词的行为或状态发生在同一时间(段)的称为"现在时",而发生在谓语动词的行为或状态之后的称为"将来时"。这个时间概念对于后面要讲的非谓语动词的句法功能是非常重要的。 2. 语态概念:与谓语动词一样,非谓语动词也有主动语态和被动语态之分。 也就是要记住四句话: (1) 表示将来时; (2) 表示现在时; (3) 表示过去时(一定是被动的) (4) 动词不定式的完成时表示过去时 非谓语动词的上述时态和语态概念是理解非谓语动词句法功能、应试判题和翻译的基础。 请你判断一下,下面句子中的非谓语动词是什么时态和语态: Your duty is to look after the sick child. (你的责任是照料这个病孩。将来/ 主动) The sick child needs to be looked after by a special person. (这个病孩需要专人照顾。将来 / 被动)

最新初中英语非谓语动词专项训练及答案 一、非谓语动词 1.Our teacher often tells us in the river. It's dangerous. A. not swim B. not to swim C. to swim D. swimming 【答案】 B 【解析】【分析】句意:游泳是危险的。题目中的 tell(告诉)是谓语,句子在连接第二个动词时,需要用 to 来连接,将其非谓语化,既不定式:to +动词原形。可以排除 A 和 D。所以可以推断出老师是告诉我们不要去游泳。因此选择不定式的否定形式,故答案为B。【点评】考查动词不定式,熟记固定搭配。 2.My brother is a humorous young man. He often tells jokes to make us .

初中非谓语动词知识点总结

非谓语动词(不定式、动名词) 【考点概述】 非谓语动词的本意是不能做谓语的词性,但是它具有谓语动词的性质。非谓语动词是英语中特有的,在汉语中没有此概念。所以在掌握此语法是比较困难的,在平时的备考之中应注意多多练习。 【考点释义】 考点一:不定式 (1)构成:to+动词原形(do)如: I like to swim. 注意:不定式有省“to”的不定式和不省“to”的不定式两类,但多数以不省“to”的不定式为主。如:I heard him (to)sing. 我听到他在唱歌。 (2)句法功能: 1. 作主语 在英语中为了避免头重脚轻,当不定式作主语时有时主语太长时我们用形式主语“it”来作“形式主语”,将真正主语移植动词不定时之后。形式主语也就是我们所说的“不定式的复合结构”。其构成为“It +be +(for/of sb) to do sth. 如: ① It is very important ( us) to study English. = To study English is very important for us. 学英语对我们来说是很重要的 ② It is very kind ( you) to help me. = To help me is very kind of you. 你帮助我太好了。 【易错警示】我们在区别“of”和“for”的方法如下: 当介词“of”或“for”后面接的代词与前面形容词之间能否构成主谓逻辑关系就决定是用介词“of”或“for”。如果能够成主谓逻辑关系时我们使用介词“of”,反之则用介词“for”。例如上述两个例子。 ①It is very important (for us) to study English. Us is very important.(不成立) 由于不能构成主谓关系,所以用介词“for”。 ②It is very kind (of you) to help me. You are very kind. (成立) 由于构成主谓关系,所以用介词“of”。 2. 作宾语 当动词不定式作宾语是表示的是一种打算、希望、命令等。如: ① I want to read English magazines every day. 我每天想读英语杂志。(表想,希望) ② I determine to go for a long holiday. 我决定去度一个长假。(表打算,决定)【归纳】常接不定式作宾语的动词有如下: want determine decide hope plan except would like 等。 3. 作宾补 当动词不定时作宾补即宾语补足语时宾补与宾语之间就会构成主谓的逻辑关系,宾补成立的条件唯此一条。 接不定式作宾补的动词有:“advice”、“ask”、“force”、“persuade”、

非谓语动词的三种形式

非谓语动词共分为三种,构成形式如下: 1.动词不定式(Infinitives): 2.现在分词和过去分词(present participles & past participles): 3. 动名词(gerunds) 下面我们依据句子的成分,来具体分析非谓语动词的不同用法。 1.非谓语动词做主语和表语 主语、表语和同位语在句子中用名词来担当,非谓语动词中动词不定式和动名词均可以用作名词,因此,动词不定式和动名词可以用来担当这三种成分。 1)非谓语动词做主语 一般情况下,用动名词来做主语的情况比较多,动词不定式用作主语的情况比较少。通常来说,在表达将来的要发生的事情时用不定式来作主语,而表达一般情况习惯性的动作时用动名词来作主语。 例如:Teaching is a tiring but satisfying job. Swimming is a good kind of exercise. To be an astronaut is Johnson’s desire. 在用it做形式主语的句子中通常用动词不定式来做真正的主语。 例如:It is necessary (for you) to give up smoking. It is everyone’s duty to protect the environment.

但是值得注意的是在各别情况下,即使是It做形式主语,真正的主语也必须用动名词,这些情况很少,所以希望同学们能单独记忆下来,以下是此类情况的一个总结。 It is/was no use/good doing sth. It is/was not any use/good doing sth. It is/was of little use/good doing sth. 2)非谓语动词做表语 非谓语动词作此成分的时候跟作主语时的规则基本一致。 在表示“目的,愿望,梦想,需求”等名词做主语时其表语应该用不定式. 例如:Her wish was to become an artist.她的愿望是成为一位艺术家 Our aim is to help them,not to teach them a lesson.我们的目的是帮助他们,而不是教训他们。 动名词做表语,表示抽象概念。动名词做表语一般用来表示“身份,职业”等.大部分时候主语与表语可以互换。 例如:My job is teaching.(Teaching is my job.) 此外,还要注意主语与表语的一致性。 例如:Seeing is believing.百闻不如一见。 To see is to believe.

非谓语动词知识点总结

非谓语动词就是不能作句子谓语而具有其他语法功能的动词。 主语/表语: 不定式和ing分词均能作主语,二者有何区别? 1.表示某一具体的动作时,多用不定式;表示比较抽象的一般行为倾向的,多用动名词。 2.动名词作主语时通常位于句首;不定式作主语时常置于句末,用it作形式主语放在句首。 1) Smoking is prohibited(禁止)here. 2) It is not very good for you to smoke so much. Seeing is believing. To see is to believe. 若主语和表语都是非谓语动词, 应保持形式上的一致。

宾语: 1. 有些动词后只跟不定式作宾语,如: …… manage, promise, pretend, plan, offer, agree, ask, dare, choose, fail, help(帮助),want(想要) , refuse等。 决心学会想希望,拒绝设法愿假装。 主动答应选计划,同意请求帮一帮。 2. 有些动词后只跟动名词作宾语,如: ……practise, appreciate, dislike, excuse, forgive, keep, resist, risk, deny, advise, fancy, complete, forbid, permit, allow, stand, refer to, give up, lead to, take to, set about, get down to, object to, succeed in, have difficulty in... 考虑建议盼原谅,承认推迟没得想。 避免错过继续练,否认完成就欣赏。 禁止想象才冒险,不禁介意准逃亡。 3.有些动词如begin, start; love, like, hate, prefer后既可以跟不定式又可以跟ing分词作宾语,意义上无多大区别(但ing分词一般表示经常性的行为;不定式表示具体的行为)。 4.有些动词后既可以跟不定式,又可以跟动名词作宾语,但意义上有明显差别。go on (stop/remember/regret)to do/doing can’t help to do / doing try to do/ doing mean to do(打算)/ doing(意味)be used to do / doing ( get used to doing)(used to do) 5.动词need, require, want作“需要”,deserve作“应受,应得”,主动表被动 定语: 不定式、ing 分词和过去分词都可以作定语,主要区别在于它们的时态意义和语态意义。 分词作定语与动词不定式作定语的区别是:现在分词表示主动、进行之意;过去分词表示被动与完成;而不定式表示在谓语动词表示的动作之后即将发生的动作。 不定式用来修饰序数词、最高级或no, all, any等限定词的中心词,表主动关系。 E.g.: The car to be bought is for his sister. / He was the best man to do the job. The houses being built are for the teachers. Developing countries/ developed countries 补语: 1.能接带to的不定式作宾语补足语和主语补足语的动词有:ask, advise, tell, force, get, allow, want, wish, like, hate, prefer, intend,expect, encourage, persuade, permit, request,order, warn, cause等。 Think, consider, believe, suppose, feel等后常用“to be....”作补语。 E.g.: You are not allowed to smoke here. People considered him to be a great leader. 2.使役动词,感官动词接不带to 的不定式作宾语补足语。常见的使役动词有make, let, have等;感官动词有see, hear, watch, observe, notice, feel以及look at, listen to等。 ◆“吾看三室两厅一感觉”---5看(look at, see, watch, notice, observe)3使(make,
