句子大全之非谓语动词可充当的句子成分

句子大全之非谓语动词可充当的句子成分

非谓语动词可充当的句子成分一、非谓语动词作主语不定式和动名词都可以作主语。

两者的区别是:表示某一具体的动作时,多用不定式;表示比较抽象的一般的行为时,多用动名词。

当动名词或不定式短语较长时,常用it作形式主语,放在句首,而把动名词或不定式短语放在句末。

例1 it took years of work ______(reduce)the industrial pollution and clean the water.解析:答案为to reduce。

括号内给出了一个动词原形reduce,但是仔细观察句子结构可知,该句已有谓语动词took,因此空格处应填非谓语动词。

“it took(takes)some time to do sth.”是固定句式,意思是“做某事花了多长时间”。

该句型中it是形式主语,真正的主语是后面的不定式短语。

二、非谓语动词作宾语不定式和动名词都可作宾语。

有些动词后只跟不定式作宾语,如want / wish / hope / manage / demand / promise / refuse / pretend / plan / offer / decide / agree / expect等。

有些动词后只跟动名词作宾语,如admit / appreciate / avoid / consider / delay/ dislike / enjoy / escape / finish / forgive / imagine / keep / mind / miss / practice / resist / risk / deny / stand等。

有些动词或动词短语后既可以跟不定式,又可以跟动名词作宾语,但意义上有区别,如forget / remember / regret / try / mean / go on等。

例2 still,the boy kept ______(ride).解析:答案为riding。

如何判断非谓语动词讲解

如何判断非谓语动词讲解

如何判断非谓语动词讲解非谓语动词是指在句子中具有动词性质,但不作谓语的动词形式。

在判断非谓语动词时,我们可以注意以下几个要点:1. 结构特征:非谓语动词通常由动词原形或动词的-ing、-ed、-en等形式构成。

常见的非谓语动词形式包括:不定式、现在分词、过去分词。

2. 句法功能:非谓语动词可以作为主语、宾语、定语、表语或状语等句子成分。

根据其在句子中的作用,我们可以判断非谓语动词的句法功能。

3. 语义特征:非谓语动词往往具有较强的动作性或状态性。

根据上下文的语义,我们可以推测非谓语动词所表达的动作或状态的特点。

以下是一些常见的非谓语动词及其用法的参考内容:1. 不定式(to + 动词原形):- 作主语:To learn a foreign language well requires a lot of practice.(学好一门外语需要大量的练习。

)- 作宾语:I want to go shopping this weekend.(这周末我想去购物。

)- 作定语:The best way to solve the problem is to ask for help.(解决问题的最好方式是寻求帮助。

)- 作状语:He woke up early to catch the first bus.(为了赶上第一辆公交车,他早早醒来。

句子成分和非谓语动词

句子成分和非谓语动词

句子成分:主语、谓语、表语、宾语、定语、状语、补足语和同位语一、主语:主语是一个句子所叙述的主体,一般位于句首。

但在there be结构、疑问句(当主语不是疑问词时)和倒装句中,主语位于谓语、助动词或情态动词后面。

主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。

例如:During the 1990s, American country music has become more and morepopular.(名词)We ofte n speak En glish in class.(代词)One-third of the students in this class are girls.(数词)To swim in the river is a great pleasure.(不定式短语)Smoki ng does harm to the health.(动名词)The rich should help the poor.(名词化的形容词)When we are going to have an English test has not been decided.(主语从句)It is necessary to master a foreign Ianguage. (it 作形式主语,真正的主语为后面的不定式)It is reported that 5000 people were killed in the earthquake. (it 作形式主语,真正的主语为后面的主语从句)二、谓语:谓语说明主语所做的动作或具有的特征和状态。

动词在句中作谓语,一般放在主语之后。

谓语的构成如下:He practices running every morni ng. (动词或动词短语)You may keep the book for two weeks. (情态动词+V 原)He has caught a bad cold. (助动词+V)We are stude nts.(系动词+ 表语)三、表语:表语用以说明主语的身份、特征和状态,它一般位于系动词(如be, become, get, look, grow, turn, seem 等)之后。

非谓语动词用法对比

非谓语动词用法对比

非谓语动词用法对比英语中动词分为两大类:一类是谓语动词,一类是非谓语动词.顾名思义,谓语动词就是在句子中做谓语的动词,即do;而非谓语动词在句子中可以做除了谓语以外的其他任何成分,即doing\to do\done.在句子中充当除谓语以外的各种句子成分的动词形式叫做非谓语动词.非谓语动词有三种:不定式、动名词和分词(现在分词和过去分词).知识要点:一、不定式与动名词做主语:1) 不定式一般表示具体的、特定的行为;而-ing分词一般表示抽象的、一般的行为。

动名词作主语时,它已经将动词名词化了,已把某个动作视为某种活动或事情了,动作意义很弱,比较抽象;而不定式作主语,动作意义强,多指“要去做某事”,这种动作往往是“要发生的一次性动作”,比较具体。

如:To complete the program needs much effort. 完成这项计划需要很大的努力。

Riding a bike can make a man smart. 骑单车能使一个人敏捷。

Smoking is forbiden. 抽烟是禁止的。

To smoke here is not very good. 在这抽烟不太好。

(2) 在疑问句中,只能用动名词的复合结构作主语。

如:Is his speaking reasonable? 她的说话有道理吗?(3) 在某些句型中通常要用动名词短语作主语。

如:It is no use doing…It is no good doing…It is useless doing…It is worthwhile doing…如:It is no use talking your trouble to a man like him. 跟他那样的人谈你的烦恼没有用。

常用不定式做主语的句型有:It’s difficult (important, necessary…) for sb. to do…It’s kind (good, friendly, polite, careless, rude, cruel, clever, foolish, brave…) of sb.to do…(4) 一般说来,作主语和表语的非谓语动词形式应一致,即:或同时为不定式,或同时为-ing 分词。

如何区分三种非谓语动词

如何区分三种非谓语动词

如何区分三种非谓语动词在英语中,动词的地位非常重要,它可以充当句子的谓语,同时受主语的限制,必须在人称上和主语一致。

另外,动词在句子中的作用不止于作谓语。

动词不定式,动名词和分词(包括现在分词和过去分词)可以出现在句子中除谓语以外的任何一个位置上,充当句子的主语,表语,定语,宾语,状语等成分,这些动词形式称为非谓语动词。

非谓语动词主要的句法功能一览表。

Ⅰ.不定式与动名词作主语的用法比较:1.动词原形不能在句中作主语。

如果某个动词在句中需作主语,我们可以把它们变成动名词或动词不定式,有时它们的意思没多大区别。

但前后要讲究对称。

如:To see is to belive. = Seeing is believing. 百闻不如一见。

2.一般来讲,在表示比较抽象笼统的一般行为时多用动名词,在表示具体某次动作,特别是将来的动作时,多用不定式。

如:Smoking is bad for health. 吸烟对人身体有害。

(笼统地谈吸烟问题)To finish the job in two days is impossible.要两天之内完成这项工作是不可能.的。

(具体地谈这项工作)3.不定式作主语时,通常用形式主语it于句首,把不定式置于句尾,使句子平稳,以避免头重脚轻。

动名词作主语用后置的情况远不及不定式那么普遍,常限于good, use, a waste of time,useless等词的后面。

如:It is impossible to finish the job in two days.It is no good /use having a car if you can’t drive.如果你不会开车,有车也没用。

It is a waste of time watching TV. 看电视是浪费时间。

4.在There is no……句型中,常用动名词作主语。

There is no doing ……没法做。

句子成分和非谓语动词

句子成分: 主语、谓语、表语、宾语、定语、状语、补足语和同位语一、主语: 主语是一个句子所叙述的主体,一般位于句首。

但在there be 结构、疑问句(当主语不是疑问词时)和倒装句中,主语位于谓语、助动词或情态动词后面。

主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。

例如:During the 1990s, American country music has become more and more popular. (名词)We often speak English in class. (代词)One-third of the students in this class are girls. (数词)To swim in the river is a great pleasure. (不定式短语)Smoking does harm to the health. (动名词)The rich should help the poor. (名词化的形容词)When we are going to have an English test has not been decided. (主语从句)It is necessary to master a foreign language. (it作形式主语,真正的主语为后面的不定式)It is reported that 5000 people were killed in the earthquake. (i t作形式主语,真正的主语为后面的主语从句)二、谓语: 谓语说明主语所做的动作或具有的特征和状态。

动词在句中作谓语,一般放在主语之后。

谓语的构成如下:He practices running every morning. (动词或动词短语)You may keep the book for two weeks. (情态动词+V原)不定式(do/to do)非谓语动词分词(现在分词doing, 过去分词done)动名词(doing)考点1 非谓语动词作状语★★★★★1. 不定式作状语I was satisfied to hear the news. (To meet the movie star I got up very early. (目的状语)I rushed to school only to find nobody was there. (结果状语)不定式表结果的固定结构:only/just to. . . ; too. . . to. . . ; so/such …asto. . . ;. . . enough(for sb. )to. . .He was too scared to say a word.The girl was so kind as to help the old man off the bus.I’m not such a fool as to believe that.I was lucky enough to be employed(雇佣) as a secretary(秘书).2. 分词作状语Hearing (hear) the good news, he jumped with great joy.Not knowing (know) what to do, I had to wait here.The girls came in, following (follow) their parents.The teacher came in, followed (follow) by some students. Seen (see) from the hill, the city looks like a garden.Seeing (see) from the hill, we can enjoy the view of the city.Given (give) more attention, the children could have grown better.Absorbed (absorb) in reading, we all didn’t hear the sound.Having driven (drive) all day, we were rather tired.【点津】①把握分词与句子逻辑主语之间的关系, 区别现在分词与过去分词; ②不定式作结果状语为主观上意想不到的结果, 现在分词作结果状语为客观上、顺其自然而产生的结果;The poor old man died, leaving nothing to his children.③准确理解形容词化的过去分词作状语的用法;④如果分词的动作和句子主语之间是主动关系, 同时分词动作发生在谓语动词之前时,则用完成式having done。

非谓语动词可充当的句子成分作者:李兰英来源:《高中生·高考指导》2015年第10期一、非谓语动词作主语不定式和动名词都可以作主语。

两者的区别是:表示某一具体的动作时,多用不定式;表示比较抽象的一般的行为时,多用动名词。

当动名词或不定式短语较长时,常用it作形式主语,放在句首,而把动名词或不定式短语放在句末。

例1 It took years of work ______(reduce)the industrial pollution and clean the water.解析:答案为to reduce。

括号内给出了一个动词原形reduce,但是仔细观察句子结构可知,该句已有谓语动词took,因此空格处应填非谓语动词。

“It took(takes) some time to do sth.”是固定句式,意思是“做某事花了多长时间”。

该句型中it是形式主语,真正的主语是后面的不定式短语。

二、非谓语动词作宾语不定式和动名词都可作宾语。

有些动词后只跟不定式作宾语,如want / wish / hope / manage / demand / promise / refuse / pretend / plan / offer / decide / agree / expect等。

有些动词后只跟动名词作宾语,如admit / appreciate / avoid / consider / delay / dislike / enjoy / escape / finish / forgive / imagine / keep / mind / miss / practice / resist / risk / deny / stand等。

有些动词或动词短语后既可以跟不定式,又可以跟动名词作宾语,但意义上有区别,如forget / remember / regret / try / mean / go on等。

四种非谓语动词都可做表语和定语,如何轻松区分它们的用法?

四种非谓语动词都可做表语和定语,如何轻松区分它们的用法?要回答这个问题,首先我们要知道有哪四种非谓语动词,还有什么叫非谓语动词或者为什么叫非谓语动词。

非谓语动词是对应谓语动词来说的,为了方便大家理解,我们拿简单句举例,大家都知道,一个简单句中只有一个谓语动词,比如I speak English. He speaks English. They speak English. 其中Speak 就是谓语动词,Speak受人称和数的影响,第一人称第二人称用原形,第三人称单数加s,第三人称复数They用原形。

但是一个句子种除去谓语动词外,还会有别的动词存在,比如I go home to do my homework.我回家写作业。

这个句子中有两个动词形式,但做谓语的只有一个就是Go, 另一个动词则采用了不定式结构to do,表回家的目的是为了写作业,作目的状语,这里的to do就是非谓语动词形式,非谓语动词to do不受人称和数的影响。

非谓语动词主要有四种形式,分别是:不定式,动名词,过去分词,现在分词。

其中因为动名词和现在分词变化都是动词+ing组成,但二者使用方式是不一样的。

下面我们在说一下什么是表语,什么是定语。

表语是用来说明主语的身份、性质、品性、特征和状态的。

不定式作表语: Today my task is to clean the window.今天我的任务是清洁窗户。

表具体,将来,含有目的性,通常是一次性的。

动名词作表语:My hobby is reading.我的爱好是阅读。

表经常发生的,抽象性的。

分词作表语:现在分词说明主语的特征,过去分词说明主语的状态。

比如: This dog is frightening. 这是条令人害怕的狗。

This dog is frightened. 这条狗很害怕。

说明狗自己的状态,可能狗 看到老虎了,很害怕,被吓到了。

那么什么是定语呢?定语是用来修饰、限定、说明名词或代词的品质与特征的。
