复合句中具有名词性质并且可以做主语、表语、同位语或宾语的从句叫名词性从句。

因此,我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。

高考热点1)怎样判断名词性从句的类别;2)连词that 和what的用法与选择3)if 与whether的区别4)同位语从句与定语从句的区别5)名词性从句必须采用的陈述语序6)it 可充当形式主语和形式宾语7)疑问词+-ever的连词和不加-ever的连词在语义上的用法和差别核心解读一1、在名词性从句中,从句都用陈述语序。

2、引导名词性从句的词叫引导词。

引导词可以分为以下几类:1)从属连词that(用于表示肯定的含义), whether, if (表示疑问),这三个词只起连接作用,不充当从句中的任何成分,除宾语从句外(that可省),这些词均不可省略。

2)连接代词有who, whom, whose, what, which, whoever, whatever, whichever等。

这些词在从句中既起连接作用,又充当从句中的成分,如主语、宾语、表语、补语,且不可省略。

3)连接副词有when, where, why, how, wherever, however等。

它们既起连词作用,本身又做从句中的状语。

3、名词性从句中的时态一致问题1)在宾语从句中,当主句是一般现在时、将来时或现在完成时,起从句的谓语根据需要用适当的时态。

当主句是一般过去时,从句用过去的某个时态,但若宾语从句表示客观真理,格言,谚语等,从句的时态仍用一般现在时。

Have you told him that when we are to leave?Teacher told us that China lies in the west of Japan.Although she was listening, she didn’t hear what he was saying because t here was so much noise.2)在主语从句、表语从句或同位语从句中,应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。

现在我们对名词性从句的要点进行梳理,以帮助同学们理清脉络。

但如果有两个或两个以上的宾语从句时,只有第一个that可以省略。

如:He said(that)he was hurt by her words and that he would not come back again.that引导的主语从句为避免头重脚轻,常用it作形式主语,而把主语从句放到后面。

what是连接代词,相当于the thing(s)that,在从句中作主语、宾语或表语。

例1 You can’t imagine how funny it is.I’m dealing with used to be your problem.A.which B.that C.what D.whatever【解析】答案为C。

名词性从句知识汇总

英语复合句是历年高考的高频考点。

名词性从句作为复合句的三大从句之一,包括主语从句、宾语从句、表语从句以及同位语从句。

其内容多、考点细、具有良好的区分度,所以一直受到高考命题人的青睐。

下面对名词性从句的必备知识以及高频考点进行系统的梳理和分析,以期为广大考生的备考助上一臂之力。

01名词性从句的引导词1. 引导词的类型英语中的从句都有引导词(有时没有引导词,是因为省略了引导词),名词性从句也不例外。

名词性从句的引导词可以分为以下三类:选择名词性从句的引导词是名词性从句的主要考点。

一般而言,对引导词的选择基于以下思路——一方面,要熟悉所有引导词的意义,进而根据语境进行选择。

另一方面,可以使用以下语法层面的技巧:①从句中缺名词(即主语、宾语、表语),用连接代词;②从句中不缺名词(即主语、宾语、表语),用连词或连接副词;③特殊情况时,从句不缺名词也可用what/which,起修饰作用,如what problems / which fruit。

【例1】(2018 全国卷III · 61)I’m not sure is more frightened, me or the female gorilla(大猩猩)that suddenly appears out of no where.【解析】句意:我不确定谁(who)更害怕,是我还是那只不知从哪里突然冒出来的雌猩猩。

首先,我们可以判断从句缺主语,所以要选择连接代词;然后,根据句意,可以确定答案为who。

【例2】(2018 江苏卷· 21)By boat is the only way to get here, which is we arrived.A.where B.when C.why D.how【解析】句意:坐船是到达这里的唯一方法,这就是我们如何(how)到达的。

这里缺一个连接副词,根据前半句的意思提示,可以确定应该填how,所以选D 项。

名词性从句(一)围绕名词性从句的连接词1、连接代词:w h o,w h o s e,w h o m,w h a t,w h i c h。

有词义,在从句中担任成分,如主语、表语、宾语、或定语等。

2、连接副词:w h e n,w h e r e,w h y,h o w。

有词义,在从句中担任成分,作状语。

3、连接词:t h a t,w h e t h e r,i f,a s i f。

t h a t无词义,在从句中不担任成分,有时可省略;i f(w h e t h e r),a s i f虽有词义,但在从句中不担任成分。

注重:1、连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。

连接代词与连接副词在从句充当句子成分,连接词w h e t h e r和i f(是否),a s i f(好象)在从句中不充当句子成分,只起连接作用。

根据句义,如果连接代词与连接副词,w h e t h e r、i f和a s i f都用不上时,才用t h a t 作连接词(t h a t本身无任何含义)。

2、不可省略的连词:(1)介词后的连词(2)围绕主语从句和同位语从句的连词不可省略。

名词性从句知识点

名词性从句知识点

名词性从句1.概念:在从句中做主语/宾语/表语/起解释说明的作用(同位语)。

或者说是起名词作用的从句。

名词性从句一律用陈述语序。

2.分类:主语从句/宾语从句/表语从句/同位语从句3.连接词:⑴连接代词(who谁,主格;whom谁,宾格;whose谁的,所有格;what什么,which哪一个,whatever无论什么,whichever无论哪个,whoever无论谁);⑵连接副词:when,where,how,why,⑶由if/whether引导,在句中意为“是否”。

用法:①句子成分完整,用that;②成分完整,意思不完整,用whether/if(是否),连接副词(when/where/why/how)/+ever;③成分不完整:指人用who(主/宾)whom(宾)whoever(主/宾)whomever(宾);指物:用what(主/宾)。

4.详解:⑴主语从句:用来充当整句话的主语。

①主语从句在复合句中作主语的名词性从句,通常放在主句谓语动词之前。

that在从句中只起连接词作用且不可省略。

Whether she will come to the party is uncertain.A.陈述句做主语从句的转化方式,用that 引导。

The earth goes around the sun.=That the earth goes around the sun is a fact.B.一般疑问句转化为主语从句,只能用whether来引导,不能用if。

一般疑问句语序转化为陈述语序。

Will it rain tomorrow?=Whether it will rain tomorrow is not know.C.特殊疑问句变为主语从句,还是用原来的疑问词引导(特殊疑问句有两种结构,一种是疑问词+一般疑问句;另一种是特殊疑问句本身就是陈述结构)What does she want?=What she wants is a trip to Lijing.她想要的是去丽江旅行。

名词性从句引入:The answer is right.(主语)What you said is right.I know you. (如何区分宾语?直接跟在动词或动词词组后面的成分)I know (that) you are right.The fact is right. (如何判断表语?直接跟在be动词或系动词如seem,look等)The fact is that he is lying.I have a notice that tomorrow is free. (同位语从句就是后面那句话是前面这个名字的具体内容)(一)名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。

因此,名词性从句分为主语从句、表语从句、宾语从句和同位从句。

练习:判断下列划线部分在句子中的成分1) What we saw in the Olympics was encouraging.2) It is exciting that Mike won a gold medal in the Olympics.3) This Middle School is not what it used to be.4) We sincerely hope that the baby can recover from his illness soon.5) His suggestion that we should act at once is practical.(二)引导名词性从句的连接词:1、从属连词:that(无词义), whether, if(是否)。

在从句中不充当成分,只起到连接从句的功能。

2、连接代词:who, whoever, whose, whom, what, whatever, which, whichever。

有具体含义,既在从句中担任成分,又能引导从句。

3、连接副词:when, whenever, where, wherever, how, why。

有词义,既作状语成分,又能引导从句。

宾语从句宾语从句可分为三类:动词的宾语从句(I beat you.)、介词的宾语从句(I amthinking of you.) 和表示“态度、情感”的形容词的宾语从句(I am so sorry.) (一)that 引导的宾语从句我认为你应该向老师寻求帮助。

I think (that) you should turn to the teacher for help.他告诉我他将于晚上八点离开大连机场。

He told me that he would leave Dalian Airport at 8 p.m.(二)if / whether 引导的宾语从句我不知道这么多年后他是否还住在这里。

I don’t know if/whether he still lives here after so many years.(三)wh-类连接词引导的宾语从句He want to know what the manager had said at the meeting.动词后的宾语从句I hope (that) you can join us in the game.Please find out when the ship sails for New York.Make sure that there are no mistakes in your paper.介词后的宾语从句介词后一般常用wh-类连接词引导宾语从句。

She is always thinking of how she can do more for others.We are talking about whether we admit students into our club.“态度、情感”的形容词的宾语从句sure、certain、glad、pleased、happy、afraid、surprised、satisfied、sorry等表示“态度、情感”的形容词后可带宾语从句。

宾语从句注意事项:(一)宾语从句的语序:陈述语序。

He asked me when we would start out the next day.修改以下句子:1)Can you tell me how many students are there in your class? (there are)2)I don’t know where has he gone.(he has gone)(二)宾语从句的时态。

主从句的两部分时态需要保持一致。

(直接引语转间接引语)主句时态从句时态例子一般现在时或一般将来时任何时态She says that she will leave a massage on his desk.他说他从来没有去过北京。

He says that he has never beento Beijing.一般过去时相应的过去时态He said that he was going to take care of the baby.他说他们那时正在开会。

He said that they were having a meeting at that time.表达客观事实、真理、规律的句子一般现在时The teacher told us thatnothing is difficult if we putour heart into it.他说光比声音传播得快得多。

He said that light travels muchfaster than sound.(三)宾语从句的否定转移。

主句谓语是think、believe、imagine、suppose、consider、expect、fancy、guess 等,从句的否定一般要转移到主句上来。

我相信他没有说谎。

(I don’t think that she is telling a lie.)我认为他们不会坚持到最后一分钟。

(I don’t think they’ll stick to the last minute.)(四)whether与if的用法及区别1)在主语从句、表语从句和同位语从句中连接词用whether,通常不用if。

Whether you can come will make a difference.The question is whether he will be show up at the meeting.I have no idea whether he will come to help us.Whether he can come to the party on time depends on the traffic.2) 动词后的宾语从句中可以使用whether或者if;但discuss后的宾语从句多用连接词whether。

I wonder if/whether you would like to join us in the outing this weekend.They were discussing whether they would start another project.3)介词后的宾语从句的连接词用whether,不用if。

I am thinking about whether I should quit my present job.4) 后跟不定式或者or not,用whether。

I don’t know whether or not he arrives.She didn’t know whether to laugh or to cry.主语从句(一)that引导的主语从句that引导主语从句,在从句中不作任何成分,也没有实际意义。

一般情况下that 不能省略。

1、that引导的主语从句位于句首That the college will take in more new students this year is true.2、形式主语it代替主语从句It is obvious that you’ve made a mistake.It is our hope that two sides will work toward peace.It is reported that no passengers were injured in the accident.在It is necessary / important / surprising / strange / unthinkable / unbelievable / incredible + that 从句结构中,从句常用should + 动词原形(should可以省略)。

It is necessary that a college student (should) master one or two foreign language.在It + be + suggested / advised / ordered / requested / required / insisted / demanded + that从句结构中,从句常用should + 动词原形(should可以省略)。

It was decided that they (should) start the project the next month.(二)whether引导的主语从句whether引导的主语从句常置于句首,if一般不引导主语从句。

Whether you can succeed or not depends on how hard you work at it.(三)wh-类连接词引导的主语从句What (=The things that) the lecture said is of great value.表语从句(一)that引导的表语从句The fact is that we should depend on ourselves.主语表示“计划,建议,要求,命令”的词,如suggestion, advice, order, demand 等时,表语从句的谓语动词常用“should + 动词原形”,should 可以省略。

My advice is that you (should) think it over before you make a decision.(二)as / as if / as though引导的表语从句同位语从句用以解释说明某一名词内容的从句,所以它总是跟在某个名词后面。
