【预习导学】
名词性从句指的是在主句中起的作用相当于________ 的从句，主要包括____________、
____________、______________和__________________。
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。
①___________ they were in truth sisters was clear from the facial similarity between them.
从她们的面貌相似度就能清楚地看出她们真是亲姐妹。
②___________ struck me most in the movie was the father’s deep love for his son.
影片中最打动我的是父亲对他儿子深深的爱。
2．主语从句一般放在句首，但有时也可用it作形式主语，而将主语从句移到句子的末尾。常见的句型：
(1)It＋be＋形容词(necessary/likely/important/uncertain等)＋that从句
(2)It＋be＋名词(短语)(a pity/a shame/no wonder/no surprise等)＋that从句
(3)It＋be＋过去分词(said/reported/decided/believed等)＋that从句
(4)It＋不及物动词(seem, appear, happen等)＋that从句
① __________________________ side effect the medicine will bring about, although about two thousand patients have taken it.

② _________________________ our team has won the game.
我们队获胜一点都不令人吃惊。
③ ______________________ the meeting will be put off till next Monday.
会议被推迟到下周一召开已经定下来了。
二、宾语从句
1．引导宾语从句的连接词：从属连词that, whether, if；连接代词what, who, whose, whatever,
whichever, whoever等；连接副词when, where, why, how等；从句用陈述语序。
①We promise _____________ attends the party a chance to have a photo taken with the movie star.

②I truly believe ____________ beauty comes from within.(2015·北京高考单选)
我确信美来自内在。
③We must find out ___________ Karl is coming, so we can book a room for him.(2015·重庆高考单选)
我们必须弄清楚卡尔什么时候来，以便我们可以为他预订房间。
2．it作形式宾语的宾语从句
(1)一些动词后的宾语从句有宾语补足语时，则需要用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 _______________________ the meeting will not be postponed.
他清楚地表明会议不会被推迟。
(2)动词hate, like, dislike, appreciate, enjoy等表示“喜欢”、“厌恶”的动词以及一些动词短语see to, depend on, rely on等常用it作形式宾语，而将宾语从句后置。
I shall ___________________ he is taken good care of when you are absent.
你不在的时候，我会确保把他照顾好。
三、表语从句
1．引导表语从句的连接词：从属连词that, whether；连接代词what, who, whose, whatever, whichever, whoever等；连接副词when, where, why, how等；从句用陈述语序。
①Jerry did not regret giving the comment but felt ____________ he could have expressed it differently.
杰里不后悔给出评论，但是觉得自己本来可以用不同的方法来表达的。
②I’d like to start my own business —that’s __________ I’d do if I had the money.
我愿意自己创业——那就是如果我有钱将会做的事情。
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 等动词之后。
The thick smog covered the whole city. It was ___________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……的原因。This/That is/was because ... 这/那是因为……The reason why ... is/was that ... ……的原因是……
①China is developing fast. _________________ I think those of my colleagues who deal with China affairs should visit China.
中国在飞速发展，这就是我为什么认为我的那些跟中国打交道的同事应该访问中国。 ②________________ he didn’t pass the exam _____________ he was too careless. 他没有通过考试的原因是他太粗心了。 四、同位语从句
同位语从句在句中作某一名词的同位语，位于该名词之后，用以说明该名词的具体内容。 1．常见的后跟同位语从句的名词有：
advice 建议 conclusion 结论 demand 要求 doubt 怀疑 fact 事实 hope 希望
idea 主意 information 信息 message 消息 news 消息 order 命令 possibility 可能性 promise 诺言 question 问题 request 请求 suggestion 建议 thought 想法 plan 计划
be different.
我对自己承诺：今年，我高中的第一年，会有所不同。
②—Is there any possibility _________ you could pick me up at the airport? —No problem.
——你有可能到机场接我吗？ ——没问题。
2．引导同位语从句的连接词有：that, whether, how, where, when, why 等。

通过多年的研究发现：有证据表明孩子的早期睡眠问题很有可能会随着他们的成长继续下去。 ②She asked a question _________ the re was a delay. 她问了发生延误的原因。
③I have no idea ____________ he will come back home. 我不知道他什么时候回家。
名师指津
在同位语从句中，that, whether不作句子成分。that无实义，whether意为“是否”，if一般不引导同位语从句。引导同位语从句的连接词一般都不能省略。
【考点突破】

考点归纳
1．what引导名词性从句的五种用法：
(1)表示“……的东西或事情”：
They’ve done what they can to help her.
他们已经尽力帮助了她。
He saves what he earns.
他赚多少，积蓄多少。
(2)表示“……的人或的样子”：

是谁把弗雷德培养成现在这个样子的？
(3)表示“……的数量或数目”：
Our income is now double what it was ten years ago.
我们现在的收入是10年前的两倍。

In 1492，Columbus reached what is now called America.1492年哥伦布到达了现在所称的美洲大陆。
2．what 与that引导名词性从句时的区别：两者均可引导主语、表语、宾语从句。that 可引导同位语从句，但 what 通常不用于引导同位语从句；what 可在从句中用作主语、宾语或表语，意为“什么”或“所……的”，而 that 仅起连接作用，本身没有实际意义，在从句中也不充当任何句子成分(引导宾语从句时通常可以省略，如果有两个或两个以上并列的宾语从句，第一个从句的引导词that可以省略，其余的不能省略)。
He doesn’t know what she likes.
他不知道她喜欢什么。
I believe (that) he will come to see us.
我相信他会来看我们的。

C．which D．what
2．After investigation，the police found out one clue ________ voices were heard calling for help from some very distant place that day.
A．where B．when
C．that D．whose
考点归纳
1．判断是同位语从句还是定语从句可以用“加词”的方法，即在名词和从句之间加入一个be 动词，如果句子意思成立，则是同位语从句，否则，则是定语从句。
The notice that the meeting had to be put off was true.(同位语从句)
→The notice was that the meeting had to be put off.
The notice that he read just now was true.(定语从句)
2．在某些名词后的同位语从句中，其谓语动词应用虚拟语气形式：(should＋)动词原形。常见的名词有demand，request，advice，suggestion，order，plan，proposal等。
The suggestion that a new bridge (should) be built was a ccepted.
在这里修建一座新桥的建议被采纳了。
考点3 名词性从句中whether与if的比较

A．whether B．when
C．which D．where
考点归纳
whether和if在宾语从句中经常可以互换，但与or或or not连用时只能用whether；从句作介词的宾语时只能用whether；在引导主语从句、表语从句和同位语从句时一般用whether不用if。

我问老师这是否是真的。

A．where B．why
C．what D．which
4．________ Li Bai，a great Chinese poet，was born is known to the public，but some won’t accept it.(2015·江苏，25)
A．That B．Why
C．Where D．How
考点归纳
连接副词指的是既具有副词的特点，同时又能引导从句的词，主要有when，where，how，why 等。这些词在从句中既作特定的成分，又有具体的含义，不能省略。大多数连接副词表示疑问意义。
When we shall meet again is unknown.
我们何时才能再相见还不知道呢。(when引导主语从句，表示疑问)

C．Whatever D．Wherever
2．Some people believe ________ has happened before or is happening now will repeat itself in the future.(2014·北京，33)
A．whatever B．whenever
C．wherever D．however
考点归纳
whichever，whatever，whoever引导名词性从句，它们本身有词义，既有连接从句的作用，又在从句中分别充当主语、宾语、定语成分，起强调作用，意思是“无论……，不管……”。
The club will give whoever wins a prize.
俱乐部将给得胜者奖励。(宾语从句)
I believe whatever he says.
我相信他所说的一切。(宾语从句)
Whoever wants to reach a distant goal must take many small steps.
不论谁，要想达到一个远大的目标，就必须采取许多细小的步骤。(主语从句)
【方法总结】
方法1 位置判断法
根据名词性从句的句子特点及其所处的位置，判断出属于哪一种从句，从而确定连接词的种类，也有助于对句子的理解。
What he said astonished us.
他所说的话使我们很惊奇。(从句在主语位置，为主语从句)
Everything depends on whether you have enough money.
一切都看你是否有足够多的钱。(从句在介词后，作介词的宾语，为宾语从句)
The question is where we’ll g o this Sunday.
问题是我们这个周日去哪儿。(从句在is后，为表语从句)
He expressed the hope that he would come to China again.
他表达了再来中国的愿望。(从句在抽象名词后，对名词进行解释说明，为同位语从句)
(1)________ some people regard as a drawback is seen as a plus by many others.
A．Whether B．What
C．That D．How
答案 B
解析句意为：一些人眼中的缺点是别人眼中的优点。分析句子可知，________ some people regard as a drawback为主语从句，且从句中缺宾语，只能用what来引导；that引导主语从句不作成分。
(2)One reason for her preference for city life is ________ she can have easy access to places like shops and restaurants.
A．that B．how
C．what D．why
答案 A
解析系动词is之后是一个表语从句，而从句的结构完整，不缺少任何成分，所以用that引导。
方法2 语序判断法
一般来说，名词性从句中(当然不只是名词性从句，其他从句也是如此)，从句的语序要用陈述语序，这样也就很容易作答了。
When changing lanes，a driver should use his turning signal to let other drivers know ________.
A．he is entering which lane
B．which lane he is entering
C．is he entering which lane
D．which lane is he entering
答案 B
解析which引导的句子作know的宾语，句子用陈述语序。故B项为正确答案。
方法3 句子成分分析法
看从句缺不缺成分，不缺就用that，whether或if；缺成分就用wh-类连接词(包括how，because 等)。
(1)We haven’t discussed yet ________ we are going to place o ur new furniture.
A．that B．which C．what D．where
答案 D
解析句意为：我们还没有讨论把我们的新家具放在哪里。分析句子可知，此题考查宾语从句。宾语从句中缺少地点状语，因此选择D。
(2)As a new graduate，he doesn’t know ________ it takes to start a business here.
A．how B．what C．when D．which
答案 B
解析句意为：作为一名新毕业生，他不知道需要什么才能在这里开始经营。空格后的宾语从句中takes是动词，其后缺少宾语，所以引导该宾语从句的连接词要用what。

【考点突破】
考点1 what和that引导的名词性从句
1. 答案 D
解析考查主语从句的引导词。句意为：通常情况下，对于那些心存希望的人来说，一切皆有可能。本句中的it为形式主语，真正的主语为后面的名词性从句，从句结构完整，不缺成分，故要用that引导。
2. 答案 B
解析考查表语从句。句意为：雨季最令人愉快的事情是人可以完全不受灰尘的袭扰。分析句子结构可知，is后的表语从句中不缺少成分，且句意完整，故选B。
3. 答案 A
解析考查表语从句的引导词。句意为：船停在港口里是很安全的，但这并非建造船的目的。空格处引导的从句作表语，表语从句中的for后缺少宾语，用what引导，故选A。why和when是连接副词，不能作宾语；whom指人。
4. 答案 A
解析考查宾语从句的引导词。句意为：如果你在河里或湖里游泳的话，务必调查清楚水面之下有什么。水中经常隐藏着石头或树枝。分析句子结构可知，此处investigate后跟宾语从句，从句缺少主语，故用what引导。who与whoever都可以作主语，但是不符合句意；that在名词性从句中仅仅起连接作用，不作句子成分。
5. 答案 A
解析考查宾语从句的引导词。句意为：读了多丽丝·莱辛的传记，我对她在文学上取得的成就钦佩不已。分析句子结构可知，介词for后接的是宾语从句，从句中缺少achieve的宾语，故用what引导。

1. 答案 B
解析考查同位语从句。句意为：经理提了个建议——我们应雇个助手。要做的工作太多了。分析句子结构可知，空格后的同位语从句用来解释说明suggestion的具体内容，从句中不缺成分且意义完整，故选B项。

1. 答案 C
解析句意为：我们给他提供了这个职位，但是不知道她是否会接受。本题考查同位语从句。whether he will accept it是对前面名词idea内容的补充说明。在同位语从句中表“是否”只可用whether不可用if。
2. 答案 A

【当堂达标】
Ⅰ.用适当的引导词填空
1．that 句意：我确信美丽源自内在。“________beauty comes from within”为宾语从句，该从句结构完整，故用 that。
2．How 句意：我们理解事物的方式与我们的认知有很大关系，“________ we understand things”为主语从句，该从句中缺少方式状语(如何)，故用 How。
3．Where 句意：李白，中国伟大的诗人，出生的地方人人皆知，但是有些人对此并不接受。“________ Li Bai, a great Chinese poet, was born”为主语从句。该从句缺少地点状语，故答案为 Where。
4．what 句意：如果你在河里或湖里游泳，一定要查明水下的状况。经常会有岩石或树枝隐藏在水中。“________ is below the water surface”为宾语从句，作动词 investigate 的宾语，该从句中缺少主语且表示“事物”，故答案为 what。
5．when 句意：我们必须弄清楚卡尔什么时候来，以便我们可以为他预订房间。“________ Karl is coming”为宾语从句，作动词短语 find out 的宾语，该从句中缺少时间状语，故答案为 when。
6．what 句意：在港口的船是安全的，但是那并不是船被建造的目的。“________ ships are built for”为表语从句，该从句中缺少宾语且表示“事物”故答案为 what。
7．how 句意：——我想知道这么些年来玛丽是如何保持体形的。——通过每天锻炼身体。“________ Mary has kept her figure after all these years”为宾语从句，该从句中缺少方式状语，故答案为 how。
8．where 句意：如果你要计划到那里的最好路线，你就得知道你将要往哪儿走。“________ you're going”为宾语从句，该从句中缺少地点状语，故答案为 where。
9．what 句意：读着她的自传，我沉浸在对 Doris Lessing 在文学上获得的成就的崇拜之中。“________ Doris Lessing had achieved in literature”为宾语从句，该从句中缺少宾语且表示“事物”，故答案为 what。
10．why 句意：这个展览告诉我们为什么我们应该做一些事情来阻止空气污染。“________ we should do someth ing to stop air pollution”为宾语从句，该从句中缺少原因状语，故答案为 why。
11．when 句意：土豆被引入欧洲的确切时间不能确定，但很可能是1565年左右。分析句子结构可知，设空处为主语从句的引导词，从 around 1565判断，这里指时间，故填 when。
12．what 句意：我认为他的画使我印象深刻的是他对色彩的使用。分析句子结构可知在主语从句________ impresses me about his painting 中，所缺的词作主语且表示“物”，所以填 what。
13．what 句意：我们很难想象古代奴隶们的生活是什么样子的。分析句子结构可知在该空引导的宾语从句中介词 like 后面缺少宾语且设空处表示“事物”，所以填 what。
14．why 句意：——迈克昨天拒绝了耶鲁大学给他的录取机会，这是真的吗？——是的，但是我不知道他为什么会这样做，那可是他最喜欢的大学之一。根据句意填 why。why 引导同位语从句。
15．what 句意：振作起来，勇气就是去做你害怕去做的事情。分析题干可知 doing 后为宾语从句，从句中缺作宾语的连接词。在宾语从句中，what 可以作主语或宾语，所以填 what。
Ⅱ.语篇填空(用适当的引导词填空)
1．that “It be＋过去分词＋that”为固定句式，其中 it 为形式主语，that 从句是真正的主语。
2．what what 引导宾语从句作 saw 的宾语，从句中缺少主语且表示事物，故用 what 引导。
3．Who “__3__ will be responsible for the accident”为主语从句，该从句中缺少主语且表示“人”，故用 who 引导。
4．whether 根据题干中的 uncertain 可知设空处表示“是否”，介词后不能由 if 来引导宾语从句，所以此处应用 whether。
5．What what 引导主语从句，在从句中作 do 的宾语。
6．that “__6__ they must find out what led to the accident”为表语从句，该从句中结构完整，不缺少任何成分，所以用 that 引导。

(完整版)高考英语【名词性从句】
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。

高考英语状语从句专项训练
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。
高考英语名词性从句考点归纳
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.
