初中英语语法讲解——非谓语动词非谓语动词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。
非谓语动词分为三种形式:不定式,动名词,和分词(分词包括现在分词和过去分词)。
1)不定式a. 有些动词可以用动名词作宾语。
例如:2. worth 的用法worth, worthy, worthwhile都是形容词,意为"值得"。
1) worth:be worth + n.当名词为金钱时,表示"…… 值得……"常见的有It ’s worth while to do./ It ’s worth(someone’s)while doingbe worth doing sth."……某事值得被做"The question is not worth discussing again and again. 这问题不值得反复讨论。
2) worthy:be worthy of +n.当名词为抽象名词时表示"……值得……"be worthy to be done "某事值得被做"The question is not worthy to be discussed again and again.3) worthwhile:be worthwhile to do sth"值得做某事"It is worthwhile to ask him to join the club.值得邀请他加入俱乐部。
典型例题It is not ____ to discuss the question again and again.A. worthB. worthyC. worthwhileD. worth while答案C. 由worth的用法可知,此句只适合词组be worthwhile to do sth.。
选C。
动词不定式动词不定式由to+动词原形构成。
专题七非谓语动词一个简单句只能有一个动词做谓语,这个动词叫谓语动词;在这个简单句中,其他没有做谓语的动词,不管有多少个,都不能做谓语,这些动词就叫非谓语动词。
谓语动词要以谓语动词形式表达出来,非谓语动词要以非谓语动词的形式表达出来。
非谓语动词包括:动词不定式-to do动名词-doing现在分词-doing过去分词-done非谓语动词,顾名思义,就是不是做谓语的动词;非谓语动词除了不做谓语,可以做主语、宾语、定语、状语和表语等各种其他句子成分。
要掌握非谓语动词的用法,就是要掌握不同非谓语动词在各个句子成分的不同含义和用法。
一、非谓语动词的用法区别从含义上大略可以区别:过去分词-done一般表示被动、完成的意思,所以从主动和被动方面先可以把过去分词和动词不定式、现在分词、动名词区分开来。
动词不定式一般表示目的、还未发生的动作。
现在分词一般表示正在进行或与谓语动词同时发生的动作。
动名词具有名词的特性,在句中一般做主语、宾语、表语。
所以,就区别to do与doing的区别就可以了。
1、to do与doing(动名词)的区别(主要是在做主语、表语和宾语时的区别)(1)做主语和表语的区别一般来说,在表示比较抽象的一般行为或者经常性行为时多用动名词;在表示具体的某次动作,特别是将来发生的动作,多作不定式。
做主语:Smoking is prohibited here.此地禁止抽烟。
To invite him to tomorrow party is necessary.邀请他参加明天的聚会是必要的。
做表语:My job is teaching English .我的工作是教英语。
Our task now is to increase food production.我们现在的任务是增加粮食产量。
表语是以下一些词,一般用动名词做真正主语:注意:it是形式主语,动名词是真正主语。
It’s no use talking like that.It’s a waste of time arguing with him.这种句型,表语是其他词,用不定式做真正主语。
非谓语动词的七种形态的用法和含义

除了以上七种形态外,非谓语动词还可以组成短语或者从句,常用于虚拟语气、句子的修饰、分句或者非限制性定语从句等。
完全掌握非谓语动词的用法对于提高英语写作和阅读水平非常重要。

非谓语动词语法讲解一、非谓语动词的概念动词的基本用法是作谓语。
当句中已经有了谓语动词了,要选或要填的动词就只能用非谓语形式了。
非谓语形式有三种:1、动词不定式:to do 2、动词的ing : doing 3、动词的过去分词:done二、三种形式的含义(基本用法)不定式:表示目的和将来;动词的ing:表示主动和进行;过去分词:表示被动和完成。

方法:看看句子中是否已有了谓语动词了2、找非谓语动词的逻辑主语。
方法:非谓语动词的逻辑主语一般是句子的主语。
3、判断主被动关系。
方法:非谓语动词与其逻辑主语的主动还是被动关系。
4、判断时间关系。
方法:分析句子,看看非谓语动词所表示的动作发生在谓语动作之前、之后还是同时。
之前常用 done; 之后常用to do; 同时常用doing.学习非谓语形式时,建议把三种形式一起来比较学习,会更加有效一些。
七、非谓语动词作主语和表语的比较1、不定式和动名词作主语和表语a. 不定式表示一次性的、具体的动词。

二. 动词不定式的用法I.作主语(1)不定式做主语时,可以直接放在谓语动词之前。

第七讲非谓语动词一、改正下列句子中的唯一错误:1.For the whole afternoon they sang and danced happily without think about their schoolwork.【答案】.think→thinking【解析】without为介词,其后接名词、代词或动名词作宾语。
故将think改为thinking。
2.Having something to do on the train,I couldn't help think about the scene of leaving and felt terribly sorry.【答案】.think→thinking【解析】couldn't help doing sth.为固定搭配,意为“情不自禁做某事”,故将think改为thinking。
3.With my eyes filling with tears,I came into Mr. Li's office.【答案】.filling→filled【解析】此处为“with+宾语+宾补”结构,fill与宾语eyes之间是动宾关系,故用过去分词作宾补4.In regard to protect the environment,we have many things to do.【答案】.protect→protecting【解析】in regard to意为“关于……”,其中to是介词,其后接名词或动名词。
故将protect改为protecting 5.Saw the 18 candles burning,I couldn't keep back my tears.【答案】.Saw→Seeing【解析】see在句中作状语,与主语之间存在主动关系,故用现在分词形式。
6.We finally realized it isn't easy to being a teacher .【答案】.being→be【解析】it is+adj.+to do sth.意为“做某事是……的”,it充当形式主语,真正的主语是动词不定式短语,to后加动词原形7.I am interested in your culture and want know more about it.【答案】.在want后加to【解析】want to do sth.为固定搭配,意为“想要做某事”。
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"。
(研究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)表示曩昔时(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。
第7讲非谓语动词[深化认知]一、非谓语动词作状语1.不定式作状语(1)动词不定式可以用作目的状语。

(4)若现在分词的动作发生在谓语动词所表示的动作之前,则用现在分词的完成形式(having done)。

3.独立成分作状语有些分词或不定式短语作状语,其形式的选择不受上下文的影响,称作独立成分。
