v1.0 可编辑可修改1高考英语名词性从句讲解【考情剖析】名词性从句是历年高考的重点和难点也是热点。
名词性从句相当于名词，可用作主句的主语、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。
引导名词性从句的衔接词有：衔接代词：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；衔接副词：when, where, why, how ，有词义，在从句中担任成分，作状语；衔接词：that, whether, if, as if ，if (whether), as if 虽有词义，但在从句中不担任成分；that 无词义，在从句中不担任成分，有时可省略。
今后对名词性从句的考查仍将集中在关联词的选用上，特别石堆what 引导的名词性从句的考查。
名词性从句与其他从句的混合考查将在今后高考中占据一席之地。
易混句型的辨析，比如it 作方式主语，主语从句后置的句型与强调句型的辨析将仍作为高考考查的重点。
【知识点归纳】名词性从句的用法在句子中起名词作用的句子叫名词从句 (Noun Clauses ）。
名词从句的功用相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不一样的语法功用，名词从句又可区分称为主语从句、宾语从句、表语从句和同位语从句。
一、引导名词性从句的衔接词引导名词性从句的衔接词可分为三类：连词：that （无任何词意）；whether, if （均表示“能不能”标明从句内容的不确定性）；as if ,as though （均表示“似乎”，“似乎”）。
以上在从句中均不充任任何成分衔接代词：what, whatever, who, whoever, whom, whose, which. Whichever, whomever 衔接副词：when, where, how, why 不可省略的连词： 1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。
第八讲名词性从句名词性从句(主语从句、宾语从句、表语从句及同位语从句)是高考卷中的难点，一般情况下，语法填空与短文改错中会出现一道题目。
书面表达中的名词性从句绝对是“增分点”。
命题趋势：名词性从句的考查点主要集中在宾语从句上，特别是引导词的选择与判断，其中what和that是考查的重点。
考点一that引导的名词性从句1．that引导主语从句①That you didn't know the rule s won't be the excuse for your failure.你不知道规则不能成为你失败的借口。
②As I searched the name Linda on the Internet，it became evident that there're two with the same name who look completely different.当我在网上搜索琳达这个名字的时候，很显然有两个看着完全不同但姓名相同的人。
③It is announced in today's newspaper that Trump will pay a visit to China next week.今天报纸上宣称特朗普下周将访问中国。
[规律总结]连词that在引导名词性从句时本身没有意义，在从句中不担任任何句子成分，但引导主语从句、表语从句、同位语从句时不能省略。
在宾语从句中有时可以省略。
1．that引导主语从句位于句首时，本身无意义，但是不可以省略。
2．that从句作主语时，常用it作形式主语，常见的句型有：①It＋be＋形容词(obvious，true，natural，surprising，good，wonderful，funny，possible，likely，certain，probable，etc.)＋that从句。
②It＋be＋名词词组(no wonder，an honor，a good thing，a pity，no surprise，etc.)＋that从句。
专题三名词性从句名词性从句指在复合句中起名词作用的从句，它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点，也是高考考查的热点。
一、名词性从句的分类名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
其连接词有 that, if, whether；连接代词 who, what, which；连接副词 when, where, how, why 等。
考查热点一：对主语从句的考查主语从句在复合句中充当主语，它可以放在主句谓语动词之前。
但为了保持句子平衡，多数情况下可用it 作形式主语，而把主语从句置于句尾。
考查热点二：对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动 make, find, see, think 等，则把宾语从句置于宾语补足语之后，用it 作形式宾语。
另外，某些作表语的形容词，如 sure, happy, glad, certain 等之后也可以带宾语从句。
考查热点三：对表语从句的考查表语从句在句子中作表语，位于主句中的系动词之后。
考查热点四：对同位语从句的考查同位语从句一般跟在某些抽象名词之后，进一步说明该名词所表示的具体内容。
可跟同位语从句的名词主要有：fact, idea, news, promise, belief, condition, doubt, fear, hope, problem, proof, question, reply, report, suggestion, thought, truth等。
二、对名词性从句的考查应注意以下几点：考查热点五：考查名词性从句的语序和主从句时态名词性从句均应用陈述句语序，其时态要保持主从句时态一致性。
考查热点六：从语境和句子结构需要出发，选择合适的连词（I）连词that 和what：that 无实际意义，在从句中不充当任何成分，只起连接主从句的作用；如 that 引导宾语从句，常可省略；如引导主语从句、表语从句或同位语从句， that 不能省略。
高中英语讲义---- 名词性从句（主从、表从、宾从，同从）1，陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。
主从可用it 做形式主语，宾从第一个that 可省略。
You study hard.主从：That you study hard is known to us.= It is known to us that you study hard.表从：My opinion is that you study hard .宾从：I think (that) you study hard. …and that (不能省略)….同从：My opinion that you study hard is known to us. *比较同从和主从！●一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。
I appreciate your idea that we have an exam every week. （that后完整—同从）I appreciate your idea that you came up with last time.（that后不完整---定从）2，一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or not时只用whether）。
Does your friend like English ?主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English.表从：My question is whether your friend likes English.宾从：I don’t know whether/ if your friend likes English.同从：My question whether your friend likes English isn’t clear.3, 特殊问句做名从用疑问词（连词）+ SV, 疑问词做主语时直接+谓语。

]2.Jane moved aimlessly down the tree-lined street, not knowing ________ she was heading.(2017·北京卷)A.whyB.whereC.howD.when答案 B [句意：Jane漫无目的地走在两旁栽树的街道上，不知道她将去往何方，根据语境可知此处是表地点的，故选B。
]3.We choose this hotel because the price for a night here is down to $20, half of ________ it used to charge.(2017·江苏卷)A.thatB.whichC.whatD.how答案 C [“half of ________ it used to charge”是$20的同位语，即本来价格的一半是如今的$20；另外，of后跟名词或名词短语构成介宾短语，所以，这里是宾语从句；宾语从句中的charge后面缺少宾语，所以用what 来引导宾语从句，并充当宾语从句中的宾语，故选C。
句意：我们选择这家宾馆是由于一夜的住宿费降到了20美元，这是该宾馆过去要价的一半。
]4.She asked me ________ I had returned the books to the library, andI admitted that I hadn’t.(2017·天津卷)A.whenB.whereC.whetherD.what答案 C [句意：他问我是否曾经把书还给图书馆了，我承认。

从句动词do需求宾语，且引导主语从句，故用whatever。
][要点精析]名词性从句指的是在主句中起的作用相当于名词的从句，次要包括主语从句、宾语从句、表语从句和同位语从句。
一、主语从句1.引导主语从句的连接词：从属连词that, whether/if；连接代词what, who,whom, whose, whatever, whichever, whoever等；连接副词when, where, why, how, whenever等。

常见的句型：·It＋be＋描述词(necessary/likely/important/uncertain等)＋that从句·It＋be＋名词(短语)(a pity/a shame/no wonder/no surprise等)＋that 从句·It＋be＋过去分词(said/reported/decided/believed等)＋that从句·It＋不及物动词(seem, appear, happen等)＋that从句It is uncertain what side effect the medicine will bring about, although about two thousand patients have taken it.尽管大约两千名患者曾经服用了这类药，但是它会带来什么样的副作用还不清晰。

(2015·北京卷·单选)2.it作方式宾语的宾语从句(1)一些动词后的宾语从句有宾语补足语时，则需求用it作形式宾语，而将that引导的宾语从句后置。
常见的这类动词有：find, feel, think, consider, believe, guess, suppose, make等。
He has made it clear that the meeting will not be postponed.他清晰地表明会议不会被推迟。
(2)动词hate, like, dislike, appreciate, enjoy等表示“爱好”、“讨厌”的动词和一些动词短语see to, depend on, rely on等常用it作方式宾语，而将宾语从句后置。

I don’t believe she will attend the meeting.我认为她不会来参加该会议。
4.that, what引导宾语从句的区别在宾语从句中，that没有词义，在从句中不作任何成分。

2.as if/as though引导的表语从句as if/as though引导的表语从句常跟在be动词，seem, look, taste, sound, feel, appear等动词以后。
The thick smog covered the whole city. It was as if a great black blanket had been thrown over it.浓雾覆盖着整座城市。
好像把一个巨大的黑色的毯子扔到它的上面。
3.because, why引导的表语从句because, why也可引导表语从句，但because引导的表语从句，主语不能是reason或cause (该结构常用that引导)。
常用于以下句型：·This/That is/was why...这/那是……的缘由。
·This/That is/was because...这/那是由于……·The reason why...is/was that...……的缘由是……From space, the earth looks blue. This is because about seventy-one percent of its surface is covered by water.从太空中看，地球是蓝色的。
