名词性从句
【定义】一个句子在另一个句子中充当主语、宾语、表语、同位语，相当于名词，故称为名词性从句。
【四大从句】名词性从句分为主语从句、宾语从句、表语从句和同位语从句。
一、主语从句
一个句子在另一个句子中充当主语，即句子充当主语，该句子称为主语从句。
【完成例句】
根据句意选词填空(that, if, whether, why, when, what)
(1) That he will succeed is certain.
(2) Whether he will go there is not known.
(3) What he said is not true.
(4) When the meeting will be held has not been decided yet.
【结论】①that－从句，从句为一个句意完整的陈述句，没有具体意义，不充当句子成分，只起标志性作用，但that 不能省略。
②whether －从句，从句来源于一般疑问句，whether不能省略，意为“是否”，不能用if替换。
③特殊疑问词－从句，从句来源于特殊疑问句，特殊疑问词不能省略，意思为特殊疑问词本来的意思，在从句中充当句子成分。
【疑难1】Who he is is none of my business.
【疑难剖析1】任何从句要用陈述句语序，即主谓语序。
【疑难2】That he likes English is known to us all.
What he said at the meeting made me sad.
【疑难剖析2】主句时态为过去时，从句时态为过去的某一时态；主句时态为现在时或将来时，从句时态视具体情况而定。
【疑难3】That 2010 Asian Games are successful is known to all.
【疑难剖析3】单个句子作主语，视为单数。
【疑难3】It is a pity that you didn't go to see the film.
It doesn't interest me whether you succeed or not.
It is in the morning that the murder took place.
It is John that broke the window.
【疑难剖析3】1．主语从句通常由it充当形式主语，而本身放在句子末尾。
2．it作形式主语和it引导强调句的比较
it作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who / whom。
3. 用it 作形式主语的常用结构[ ]
① It is ＋名词＋从句
It is a fact that…事实是……
It is an honor that…非常荣幸
It is common knowledge that………是常识
②It is ＋形容词＋从句
It is natural that…很自然……
It is strange that…奇怪的是……
③It is ＋不及物动词＋从句
It seems that…似乎……
It happened that…碰巧……
It appears that…似乎……[ ]
④It ＋过去分词＋从句
It is reported that…据报道……
It has been proved that…已证实……
It is said that…据说……
【疑难5】It is said that Chairman Hu will visit our school next week. (√)[ ]
That Chairman Hu will visit our school next week is said. (×)
【疑难剖析5】主语从句不可位于句首的五种情况：
1. if 引导的主语从句不可位于复合句句首。
2. It is said / reported…结构中的主语从句不可提前。
3. It happens / occurs…结构中的主语从句不可提前。[ ]
It occurred to him that he failed in the examination. (√)
That he failed in the examination occurred to him. (×)
4. It d oesn't matter how / whether…结构中的主语从句不可提前。
It doesn't matter whether he is wrong or not. (√)
Whether he is wrong or not doesn't matter. (×)
5. 含主语从句的复合句是疑问句时，主语从句不可提前。
Is it likely that it will rain in the evening？(√)
Is that will rain in the evening likely？(×)
【疑难6】what 与that 在引导主语从句时的区别
What you said yesterday is right.
That she is still alive is a consolation.
【疑难剖析6】what 引导主语从句时在从句中充当主语、宾语或表语，而that则不充当任何成分。
二、宾语从句
在复合句中作宾语的名词性从句是宾语从句，通常放在主句谓语动词(及物动词)或介词之后。
【完成例句】[ ]
根据句意选词填空(that, if, whether, where, what，who)
(5)I heard that he joined the army.
(6)①She did not know what had happened.
②I wonder whether you can change this note for me.
(7)She told me that she would accept my invitation.
【结论9】①由that引导的宾语从句(that 通常可以省略)，that在从句中不充当任何成分。
②由what引导的宾语从句，what在从句中充当主语、宾语或表语。
③whether (if)引导的宾语从句，在从句中不充当任何成分，只起连接作用，意为“是否”。【疑难1】引导宾语从句时if和whether的区别
I asked her if / whether she had a bike.
They discussed whether they will go back right now.
We're worried about whether he is safe.
I don't know whether or not he will come.
I don't know whether to go.
【疑难剖析1】引导宾语从句时用if和whether都可以，但有只用whether的特殊情况：动词discuss后；介词后；whether与or not连用时；whether to do。
【疑难2】I am afraid (that) I've made a mistake.
【疑难剖析2】作形容词的宾语时，可以省略that。
【注意】下列形容词后常跟that引导的从句作宾语：
anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content等。(有时也将此类词后的that 从句看作原因状语从句。)
【疑难3】We heard it that she would get married next month.
【疑难剖析3】it 不仅可以作为形式主语，还可以作为形式宾语，而真正的宾语that 从句则放在句尾(特别是在带复合宾语的句子中)。
【疑难4】I admire their winning the match. (√)
I admire that they won the match. (×)
【疑难剖析4】后边不能直接跟that 从句的动词有：
allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。这类词后可以用不定式或动名词作宾语，但不可以用that引导的宾语从句。【疑难5】He impressed the manager as an honest man. (√)
He impressed the manager that he was an honest man. (×)
【疑难剖析5】有些动词不可用于“动词＋间接宾语＋that－从句”结构中，这类动词常见的有envy，order，accuse，refuse，impress，forgive，blame，denounce，advise，congratulate 等。
【疑难6】我认为这件衣服不适合你穿。
I don't think this dress fits you well.
【疑难剖析6】否定的转移：若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。
三、表语从句
在复合句中作表语的名词性从句为表语从句，一般结构是“主语＋连系动词＋表语从句”。
【完成例句】
根据句意填空
(8) The question is whether we can make good preparation in such a short time.
(9) This is why we can't get the support of the people.
(10) But the fact remains that we are behind the other classes.
(11) The reason he is late for school is that he missed the early bus.
【结论1】
①完整陈述句充当表语时用that引导，且不可省略；
②表“是否”含义时用whether；
③语义不完整时根据情况选用对应的特殊疑问词，如what，when，where，why等；
④两种特殊句型：the reason is that…和It is because…等结构。
四、同位语从句
在复合句中作名词的同位语的名词性从句为同位语从句。
【完成例句】
根据句意选词填空
(12) The king's decision that the prisoner would be set free surprised all the people.
(13) The order that all the soldiers should stay still is given by the general.
【结论】同位语从句对名词作进一步解释，说明名词的具体内容，一般由that引导，可以接同位语从句的名词主要有：fact, information, problem, decision, suggestion, proposal, order 等。
【疑难1】同位语在句子中的位置
He got the news from Mary than the sports meeting was put off.
【疑难剖析1】同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。【疑难2】同位语从句与定语从句的区别
The news that he told me is that Tom would go abroad next year.
他告诉我的消息是汤姆明年将出国。
The news that Tom would go abroad is told by him. 汤姆将出国的消息是他讲的。
【疑难剖析2】(1)定语从句中的that既代替先行词，同时可以在从句中作某个成分(主语或宾语)，而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2)定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述名词的性质或特征；同位语从句是名词性的，其功能是对名词的具体内容进行补充说明。

2019届二轮复习语法专题名词性从句学案 在复合句中起到名词作用的从句叫名词性从句，包括主语从句，表语从句，宾语从句和同位语从句。引导名词性从句的词有：连词that，whether，if；连接代词和连接副词what, which, who, whom, whose, when, where, why，how等。名词性从句可以表示两方面：一个事实，一个问题。问题又分两方面即一般问句和特殊问句，请看下图： 一、主语从句就是做主语的从句。它由 that 和其他疑问词引导。 1．That they are rich is true, isn't it? (that 不能省略) 2．Where he got it is unknown to us. 3．They lost their way in the woods, and what made matters worse was that night began to fall. 4．Whoever said that was wrong. 5．______ ______ _______ ______ _______ ______ ______ (地球围绕太阳转) is a truth. 6．_______ _______ _______ (任何努力学习的人) will pass the exam. 7．______ ____ _____ ______(我所告诉你的) just now was what had been written in the letter. 8．_______ ______ _________ _____ _______ _____ _____ ____( 我是接受礼物还是拒绝它)is none of your business. 有时用 it 作形式主语，而把真正的主语从句移到后面。其句型有： a.

专题十名词性从句 第一节基本知识与基本概念 【什么是名词性从句？】 顾名思义，主语从句在句子中作主语。有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。从句作主语时，谓语动词一般为单数形式。如: What I saw was beyond any verbal description. That his hair was turning grey worried him a bit. Why the company denied the contract is still unknown. When and where the government will build a city square is under discussion. It is pretty annoying that a small part of the machine is missing. It remains to be seen whether the new novel will be well received. 【宾语从句】 在句子中作宾语的从句就是宾语从句。由于这是同学们接触比较早的一种从句，应该问题不大。所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。如： We assumed that there would be more than 100 guests. He told the police in detail what he saw and heard. Nobody is sure what humans will look like in a million years. That will depend on whether they can get the chance. Whether I will have the time I am not sure at the moment. The conductor complained that we were not gifted in singing and that he would never come again. 【表语从句】 表语从句的最重要脸谱就是它们应该出现在系动词的后面。如： The only question left is how often the workers are paid. His idea for the coming weekend is that we go skating. 【同位语从句】 从脸谱上看，同位语从句最为麻烦。因为它们也是出现在一个名词的后面，起着解释说明的作用。

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。 一、什么是表语（predicative） 在形式上，位于系动词后的就是表语。从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分。即是指“是”字句“是”字后面的成分。表语就是起表述作用的句子成分。它修饰的是主语。表语是用来说明主语的身份、性质、品性、特征和状态的。表语须和连系动词一起构成句子的复合谓语。表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当，它常位于连系动词（be, become, appear, seem等）之后。 Albert Einstein was a famous professor of physics.

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。

让步状语从句：though/although不可同but连用。 though/although （虽然）however （可是）even though/if（即使） no matter+what/which/where/who/when =whatever/whichever/wherever/whoever/whenever （不论什么/哪一个/哪里/谁/何时） 比较状语从句：as （正如）as…as（和……一样）not as/so … as （不如……）than（比……更）the+比较级…+the+比较级（越……越……） 条件状语从句：if（假设）unless（如果不）so long as（只要）on condition that （如果） * 方式状语从句：as（像……那样地）just as（正像）as if（好像）as though（好像） 二．各种状语从句的简化方法： 1 作状语。 】 例：After she sang，she left the rich man's house．= After singing，she left the rich man's house．2．以as soon as引导的状语从句的主语若与主句主语一致时，从句等于on+doing sth.,作状语，此时的动词为非延续性动词。 例：Mary began to operate on the wounded soldiers as soon as he arrived at the village． = Mary began to operate on the wounded soldiers on arriving at the village． 3．时间状语从句和条件状语从句的主语和主句主语一致时，有时可简化为不定式作状语。 例：She stopped when she saw her husband．= She stopped to see her husband．If you want to understand the farmers，you must go to the countryside． = To understand the farmers，you must go to the countryside． 4．结果状语从句和目的状语从句的主语与主句主语一致时，可以简化为不定式作状语；若两者主语不一致时，则应简化为不定式的复合结构作状语。 例：He was so tired that he couldn't go any further．= He was too tired to go any further． I came here so that I could ask some questions．= I came here(in order) to ask some questions．5．以when，while引导的时间状语从句和以if引导的条件状语从句的主语若与主句主语一致时，从句等于when/while/if +doing sth.作状语，表示谓语动作发生在该状语动作的进行过程之中。 。 例：When he turned on the radio，he found it broken．= When turning on the radio，he found it broken．While she was walking along the street，she was hit by a car．= While walking along the street，she was hit by a car． 6．原因状语从句的主语与主句主语一致时，可简化为分词短语作状语。 例：Since l didn't know Chinese，I tried to speak to her in English．= Not knowing Chinese，I tried to speak to her in English． 注意：形容词短语也可作表示原因的状语，来代替原因状语从句，放在句首、句末均可，但一般应加逗号。 例：As he was thirsty and eager to get a little rest，he went into the tea-house． = Thirsty and eager to get a little rest，he went into the tea-house．

英语名词性从句十大考点全攻略 Who/whoever，what/whatever等的用法区别 一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为“无论什么/无论谁”。 Itisgenerallyconsideredunwisetogiveachild____heorshewants. A.however B.whatever C.whichever D.whenever 解析：答案是B，whatever引导一个宾语从句，并且作wants 的宾语。这里的whatever不能改成what，因为题意想表达的显然是“无论孩子要什么就给他/她什么事不明智的”，具有泛指的概念。同时要注意，这里whatever也不能改用nomatterwhat，因为后者只能引导状语从句。比较下例： Ican’trememberatthemomentwhohassaidthewords.(这里的who表特定的某人) Where，when，why等连接副词引导的名词性从句 Where，when，why等连接副词也可以引导名词性从句，使用的关键是：这个词必须符合句子的逻辑要求。 —IdrovetoZhuhaifortheairshowlastweek. —Isthat____youhadafewdaysoff？ A.why B.when C.that D.where 解析：答案是A，why引导的从句作表语，同时why在从句中作原因状语。这里之所以选why，而不是when或where等，唯一的依据便是句子的逻辑含义，及语境。
“介词+who(m)引导的宾语从句”与“介词+whom”引导的定语从句的区别 介词后面的引导词用主格还是宾格，决定于它在宾语从句中作主语还是宾语。 Itwasamatterof____wouldtaketheposition. A.who B.whoever C.whom D.whomever 解析：答案是A。这是一个含宾语从句的复合句，作介词of宾语的，是后面的整个句子，而不是宾语从句的引导词，由于这里引导词在从句中作主语，所以要用主格who(作宾语时自然要用whom)。 名词性从句中有插入成分时 此时应注意两点：一是从句仍然不倒装，而在插入成分上倒装；二是要注意主语的主格和宾格的选择。 ____youhaveseenbothfighters，____willwin？ A.Since；doyouthinkwho B.As；whoyouthink C.When；whoever D.Since；whodoyouthink 解析：根据上面的讲解，不难知道答案是D。其中doyouthink 是插入成分，其余部分是宾语从句，作think的宾语；由于引导词在从句中作主语，所以要用主格who(不用whom)。 引导词that的省略 引导宾语从句时，that通常可以省略，但引导主语、表语和同位语从句时，that不能省。例如：
