高考英语语法复习三：名词性从句
高考英语语法必考知识点：名词性从句
高考英语语法必考知识点：名词性从句1什么叫名词性从句从命名法的角度，名词性从句拆开来就是名词性的一个从句。
从句，顾名思义它是从属的成分，它是从属于主句存在的，不能单独存在，就类似于一个家里面一个大人带着一个小孩才能去玩，不能这个小孩自己单独去玩。
名词性顾名思义这个从句它是一个名词性的，就相当于这个从句它就是个名词，那么它在主句中要充当名词能充当的成分。
主句中名词的成分可以是主语、宾语、表语、同位语，所以名词性从句就是用一个句子在主句中充当主语或者宾语或者同位语或者表语的这样的成分，可以简单地记成名词性从句，包括主宾表同四大从句，这个就是名词性从句的本质和功能。
2名词性从句的难点(1)对名词性从句本质的理解和句子结构的划分名词性从句是镶嵌在主句中的，它不像定语从句，定语从句是主句穿了一个马甲，比如主谓宾，然后在主语后面加一个定语从句来修饰这个主语，而名词性从句不一样，它是直接用这个从句去做主句的主语或者做主句的宾语，所以在理解的时候名词性从句是没有办法拿掉的，一定要和主句一起来理解，那么这就是在划分名词性从句结构，分析句子结构的时候的一个难点。
(2)具体的引导词的用法没有办法直接把两个句子合在一起，就不得不说一个句子是从句，这样就一定要有标记词来告诉我们，这个句子是一个从句。
举个例子：我知道他迟到了。
在这句话中，我是主语，知道是谓语。
他迟到了这件事作为宾语。
所以他迟到了就是作为宾语从句。
在英语中不能直接说我知道他迟到了。
而是说我知道that他迟到了。
因为这个that的存在就把他迟到了这件事变成了一个名词性从句的成分，整个句子就相当于是一个名词作主句的宾语。
那么主语从句、表语从句和同位语从句也是一样的道理，需要在这个从句前面加一个引导词来表明这个从句的身份，给他戴个帽子。
所以在学习从句的时候的两个难点，一个是名词性从句，本质的理解，句子结构的划分，而另一个就是具体的引导词的用法，这一个是同学们在学习的时候一定要重点注意的。
高考英语语法填空之名词性从句
高考英语语法填空之名词性从句一：知识储备1．确定是名词性从句设空处无提示词，先确定主句主谓结构；再确定设空和设空后的内容在主句中充当主语、宾语、表语或同位语。
2．利用2个技巧搞定名词性从句技巧1分析句子成分①缺少主语、宾语、表语：用连接代词what，who，whom，which，whatever，whose等。
②缺少状语(结合句意判断)：用连接副词where(表地点)，when(表时间)，how(表方式)，why(表原因)等。
③不缺成分，句意缺少“是否”：用if/whether。
④不缺成分且句子意义完整：用that。
技巧2句意语境巧解题有些引导词在句中有很鲜明的意义，如if“如果”，whoever“无论谁”，whatever“无论什么”，because“因为”，why“为什么”等。
结合句意翻译和语境，不难解决这类试题。
3．牢记what和that的区别①that没有词义，也不做任何成分，当从句意义完整，不缺任何成分时用that；②What在从句中表示“……的(东西)”(有时候可以不译)，在从句中充当主语、宾语、表语、定语等成分。
二：真题精析1．By boat is the only way to get here, which is we arrived.2．Every year, makes the most beautiful kite will win a prize in the Kite Festival.3．She asked me I had returned the books to the library, and I admitted that I hadn't.4．Jane moved aimlessly down the tree－lined street, not knowing she was heading.5．Eventually, I decided to follow her and happened truly amazed me.6．I didn't understand this would happen and my credit card had already been charged.7．What students do at college seems to matter much more than they go.8．Scientists have obtained more evidence plastic is finding its way into the human body. 三：课后练习（A）In 1863 the first underground passenger railway in the world opened in London.It ran for just under seven kilometers and allowed people to avoid terrible 1(crowd) on the roads above as they travelled to and 2 work.It took three years to complete and was built using an interesting method.This included digging up the road, 3(lay) the track and then building a strong roof over 4top.When all those had been done,the road surface was replaced.Steam engines 5(use) to pull the carriages and it must have been 6(fair)unpleasant for the passengers,with all the smoke and noise.However,the railway quickly proved to be a great success and within six months,more than 25,000 people were using 7every day.Later,engineers 8(manage) to construct railways in a system of deep tunnels (隧道),which became known as the Tube.This development was only possible with the 9(introduce) of electric-powered engines and lifts.The Central London Railway was one of the most 10(success) of these new lines,and was opened in 1900.It had white-painted tunnels and bright red carriages,and proved extremely popular with the public.（B）My mom was a nurse and often took me along to visit the 1(family) she was caring for,including one who had a series of strokes(中风) and was bedridden.One afternoon Mom told me that we needed to visit the woman 2(give) her medications,and that we would stop at a store 3the way.I thought we would stop at a drugstore,but we pulled up to a shopping mall.My mom 4(head) to the perfume counter and bought the most expensive bottle they offered.She also bought a beautiful nightdress.When I asked her who they were for,she said they were for her patient.She 5 (far) explained although this woman was quite old and bedridden,she was still a lady,and 6old deserved to be treated with respect and grace.When 7(care) for someone,we should look past the disability or the illness and look into the soul of the human,so we can connect them with sympathy.I soon realized that my mom’s greatest 8(strong) was taking care of those who cannot advocate for 9(they) and need trustworthy care providers.Actually,that’s the very reason 10I wanted to become a doctor myself.（C）China is the birthplace of kites.Most people believe they 1(invent) during the Spring and Autumn Period by the famous philosopher Mozi.It is said that he used wood to create a “ 2(fly) bird” that flew in the sky for a whole day.Kites were 3(late) used as military instruments to measure distance,test the wind, aid communication, and rescue people. During the Tang Dynasty, they were used more as a tool for 4(entertain) than a military instrument.At first,only royal family members could play with kites. Later it became popular among commoners who flew them on 5(importance) events and festivals.In the Ming Dynasty, kites were once again used 6military purposes. Many emperors ordered their soldiers to fly kites 7carried explosives.The explosives would fall on the enemy and gave the Chinese a great edge on the battlefield.Nowadays,flying kites has become 8popular form of entertainment and competition.More and more people at home and abroad are fond of flying kites in local or international events 9(show) their kite-making and kite-flying skills.The largest kite museum of the world is in the city of Weifang,10(know) as “Kite Capital of the World”,and every year,kite fans all over the world come to watch and take part in the annual International Kite Festival.。
高考英语语法之名词性从句
1.名词：表示人或事物的名称的词叫名词。 2.名词的句法作用：名词在句中主要作主语、宾 语、表语和同位语。另外还可以作定语、状语。 3.名词性从句： 在英语的句子结构中，本来该由名词充当的主 语、宾语、表语和同位语，由一个句子来充当， 这个句子就叫名词性从句。 4.名词性从句的种类： 根据名词性从句在句子中所充当的不同成分， 名词性从句可以分为主语从句、宾语从句、表 语从句和同位语从句。
2.When he will go to America is not yet fixed.
(It is not yet fixed when he will go to America.)

高中英语语法：名词性从句知识汇总
高中英语语法：名词性从句知识汇总在复合句中具有名词的性质的作主语、表语、同位语、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。
当名词性从句要采用陈述句语序。
由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。
一、引导名词性从句的关联词引导名词性从句的关联词大致相同，它们分别是：连词：that, whether, if；关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever。
引导从句时一般不用逗号和主句分开。
连词that在从句中不作成分，不含疑问意义；而wh-连词在从句中作成分，且含有疑问意义；或what/where从句相当于一个名词后加一个定语从句。
It worried her a bit that her hair was turning grey.她的头发在变白令她有点担忧。
（that在从句中只起引导词作用，不作成分）What caused the accident is still a complete mystery.事故发生的原因仍然是个不解之谜。
（What在从句中作主语）2、that与whether引导名词性从句的区别。
（1）动词doubt表示“怀疑、不知道”解时，肯定句接whether引导的宾语从句；否定句don’t doubt和疑问句Do you doubt要接that引导的从句。
I don’t doubt that he will come soon.我不怀疑他不久会来。
（此处不用whether）Can you doubt that he will win?你怀疑他会赢吗？（此处不用whether）比较：doubt表示“不信”解时，表示强烈的不相信时，在陈述句中可接that从句。

高考语法填空抢分热点之名词性从句一、考点精讲名词性从句的引导词：1.that 无词义，只起引导作用，可以省略，但两个或两个以上that引导的宾语从句并列时，从第二个开始that不能省略。
2.what引导名词性从句，既起引导作用，又在从句中作一个成分，起双重作用，不能省略。
3.连词whether“是否”，可以引导主语从句、表语从句、介词之后的宾语从句以及同位语从句，而if“是否”只能引导动词后面的宾语从句。
4.引导名词性从句的连接副词有when、where、how、why，在判断名词性从句引导词的使用时，如果句子缺成分，缺什么，补什么。
二、高考题经典解读1.______(56) is so breathtaking about the experience is the out-of-this-world scenes.【答案】What【解析】考查主语从句。
句意：这段经历最让人激动的是那些脱离世界的场景。
设空处无提示词，应考虑填冠词、介词、连接词，又因为空格在句首，后面是谓语动词is，这里应该填一个连接词，引导主语从句，从句缺少引导词和主语，且指物，所以连接代词What符合语境，其双重作用。
位于句首，首字母用大写。
故答为What。
2.While they are rare north of 88℃，there is evidence ______ they range all the way across the Arctic，and as far south as James Bay in Canada.【答案】that【解析】考查同位语从句。
句意：虽然它们在88℃以北很少见，但有证据表明，它们一直分布在北极，南至加拿大的詹姆斯湾。
该句是含让步状语从句的复合句，主句部分是there be句型，设空处填that，引导同位语从句，说明evidence的具体内容。
故答案为that。
3.Research suggests an increase in voice is a signal ________ someone is lying.【答案】that【解析】考查同位语从句。
高考英语三大从句(名词性从句、定语从句、状语从句)讲解+练习(附答案)
高考英语三大从句讲解+练习（附答案）【名词性从句】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，名词性从句成分为主语从句、表语从句、宾语从句和同位从句。
（一）引导名词性从句的连接词1、连接代词：who, whose, whom, what, which。
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：when, where, why, how。
有词义，在从句中担任成分，作状语。
3、连接词：that, whether, if, as if。
that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。
1. 主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词that，whether，if和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。
that在句中无词义，只起连接作用；连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。
例如：What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced.英语晚会将在哪里举行，还没有宣布。
有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句（3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…注意：连词that, whether在从句中不担任句子成分，只起连接作用，不能省略。

名词性从句一、定义：在复合句中相当于一个名词，做主语、宾语、表语、同位语的从句。
二、引导词：1. 连词:that , if, whether, as if2. 连接代词:who , what, which, whose, whom以及wh+ever3. 连接副词:when, where, why, because, how三、引导词的作用：1 连词只有连接的功能，而不在从句中充当句子成分。
2. 连接代词和连接副词不但有连接的功能，同时还要在从句中充当定的句子成分，如主语、宾语、表语、定语、状语四、各个句型的注意点（一）主语从句1.一个主语从句的谓语动词用单数。
2.通常为了句子平衡用it做形式主语,而将主语从句放于句尾。
3.由that引导的从句，that虽然没有什么意思，但是却不能省略。
4.WH引导的从句,引导词放于句首，从句用陈述句语序。
5.放于句首时表示是否只用whether, 用IT做形式主语之后，主语从句放于句尾时whether与if均可以。
(二)宾语从句1.that引导宾语从句无意义，不充当句子成分常省略。
但下列情况除外：（1）介词宾语从句的that不省略（2）and连接的几个从句，第二个从句以后的从句的that不省略。
He told me that he had two sons and that they both had gone to college.（3）在动词+it+宾语补足语+宾语从句结构中，that不省略。
I heard it said that he had gone abroadWe found it impossible that he could finish it in such a short time2.Whether ,if 引导宾语从句：两词可互换，但是下列情形除外：（1）whether从句中有or not（2）whether从句做介词宾语Everything depends on whether you agree with us3.许多带复合宾语的句子，宾语从句经常移到句子后部，而用it做形式宾语。

高考英语语法复习三:名词性从句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,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。
(一引导名词性从句的连接词1、连接代词:who, whose, whom, what, which。
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:when, where, why, how。
有词义,在从句中担任成分,作状语。
3、连接词:that, whether, if, as if。
that 无词义,在从句中不担任成分,有时可省略; if (whether, as if虽有词义,但在从句中不担任成分。
注意: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whether 和if(是否,as if(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,whether、if 和as if 都用不上时,才用that作连接词(that本身无任何含义。
(二主语从句1、主语从句在复合句作主语。
e.g. Who will go is not important.2、用it作形式主语,主语从句放在句末。
e.g. It doesn't matter so much whether you will come or not.3、that引导主语从句时,不能省略。
e.g. That he suddenly fell ill last week made us surprised.(三表语从句1、表语从句在复合句中作表语,位于系动词之后。
e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。
e.g. My idea is (that we can get more comrades to help in the work.(四宾语从句1、宾语从句在复合句中作宾语。
引导宾语从句的连词that一般可省略。
e.g. I hope (that everything is all right.2、介词之后的宾语从句,不可用which或if连接,要分别用what或whether。
e.g. I'm interested in whether you've finished the work..I'm interested in what you've said.3、whether与if都可以引导宾语从句,常可互换。
但下面情况不能互换。
①宾语从句是否定句时,只用if,不用whether。
e.g. I wonder if it doesn't rain.②用if 会引起误解,就要用whether。
e.g. Please let me know whether you want to go.(此句如果把whether改成if,容易当成条件句理解③宾语从句中的whether 与or not直接连用,就不能换成if;不直接连用,可换。
e.g. I don't know whether or not the report is true.I don't know whether/ if the report is true or not.④介词后的宾语从句要用whether引导。
whether 可与不定式连用。
whether也可引导主语从句、表语从句、同位语从句,还可引导让步状语从句,以上均不能换成if。
但引导条件从句时,只能用if,而不能用whether。
e.g. It depends on whether we have enough time.They don't know whether to go there.Please come to see me if you have time.(五同位语从句同位语从句在句中作某一名词的同位语,一般位于该名词(如:news, fact, idea, suggestion, promise等之后,说明该名词的具体内容。
e.g. I have no idea when he will be back.The fact that he had not said anything surprised everybody.练习:名词性从句一、判断下列各句哪句含有名词性从句,并指出是什么从句:1. China is no longer what it used to be.2.
