从句
名词性从句
在句子中起名词作用的句子叫名词性从句（Noun Clauses）。名词性从句的功能相当于名词词组，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同的语法功能，名词性从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
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。
如果what-分句本身明显表示复数意义，比如what分句的动词和补语都是复数，那么主句动词也可用复数。
如：What I say and think are none of your business.(我说的和我想的都与你无关。)注意：当what引导的名词性分句作主语时，主谓一致问题极为复杂。著名学者周海中教授在论文《关于what-分句作主语的主谓一致问题》中就这一问题做了深入研究，并给出了10种的主谓一致关系。这些一致关系值得英语学习者和使用者特别注意。
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：
⑴It + be + 名词+ that从句
⑵It + be + 形容词+ that从句
⑶It + be + 动词的过去分词+ that从句
⑷It +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 suggested (requested, proposed, desired, etc.) that…
宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。
1. 由连接词that引导的宾语从句
由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时，第二个分句前的that不可省。例如：
He has told me that he will go to Shanghai tomorrow.
他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing.
我们决不能认为自己什么都好，别人什么都不好。
注意：在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。例如：
I insist that she (should) do her work alone.
我坚持要她自己工作。
The commander ordered that troops (should) set off at once.
司令员命令部队马上出发。
2.用who, whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句，应注意句子语序要用陈述语序。例如：
I want to know what he has told you.
我想知道他告诉了你什么。
3. 用whether或if引导的宾语从句，其主语和谓语的顺序也不能颠倒，仍保持陈述句语序。此外，whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether，不用if：
a. 引导主语从句并在句首时；
b. 引导表语从句时；
c. 引导从句作介词宾语时；
d. 从句后有“or not”时；
e. 后接动词不定式时。例如：
Whether there is life on the moon is an interesting question.
月球上有没有生命是个有趣的问题。
4. 注意宾语从句中的时态呼应，当主句动词是现在时，从句根据自身的句子情况，而使用
不同时态。例如：
He studies English every day. （从句用一般现在时）
He studied English last term. （从句用一般过去时）
I know (that) he will study English next year. （从句用一般将来时）
he has studied English since 2019. （从句用现在完成时）
当主句动词是过去时态（could, would除外），从句则要用相应的过去时态，如一般过去时，过去进行时，过去将来时等；当从句表示的是客观真理，科学原理，自然现象，则从句仍用现在时态。例如：
The teacher told us that Tom had left us for America．
5. think, believe, imagine, suppose等等动词引起的否定性宾语从句中，要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如：
We don’t think you are here. 我们认为你不在这。
I don’t believ e he will do so. 我相信他不会这样做。
表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样，表语从句位于联系动词后，有时用as if引导。其基本结构为：主语+ 系动词+ that从句。例如：
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That’s just what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的，当主语是reason时，表语从句要用that引导而不是because。例如：
The reason why he was late was that he missed the train by one minute this morning.
【注意】whether 可引导表语从句，但与之同义的if却通常不用于引导表语从句。
同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如：
The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别：
that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。
试比较下面两个例句：
I had no idea that you were here．（that引导同位语从句，不能省略）
Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）
其他从句
that从句
5.1）由从属连词that引导的从句叫做名词性that-从句。That只起连接主句和从句的作用，在从句中不担任任何成分，本身也没有词义。名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语，例如：
主语：That she is still alive is her luck. 她还活着全靠运气。
宾语：John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。
表语：The fact is that he has not been seen recently. 事实是最近谁也没有见过他。
同位语：The fact that he has not been seen recently disturbs everyone in his office.
最近谁也没有见过他，这一事实令办公室所有的人不安。
形容词宾语：I am glad that you are satisfied with your job.
你对工作满意我感到很高兴。
5.2)That-从句做主语通常用it作先行词，而将that-从句置于句末，例如：
It is quite clear that the whole project is doomed to failure. 很清楚，整个计划注定要失败。
It's a pity that you should have to leave. 你非走不可真是件憾事。
用it作形式主语的that-从句有以下四种不同的搭配关系：
a. It + be +形容词+ that-从句
It is necessary that…有必要……
It is important that…重要的是……
It is obvious that…很明显……
b. It + be + -ed分词+ that-从句
It is believed that…人们相信……
It is known to all that…众所周知……
It has been decided that…已决定……
c. It + be +名词+ that-从句
It is common knowledge that………是常识
It is a surprise that…令人惊奇的是……
It is a fact that…事实是……
d. It +不及物动词+ that-从句
It appears that…似乎……
It happens that…碰巧……
It occurred to me that…我突然想起……
wh-从句
6.1）由wh-词引导的名词从句叫做名词性wh-从句。Wh-词包括who, whom, whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。Wh-从句的语法功能除了和that-从句一样外，还可充当介词宾语、宾语补语和间接宾语等，例如：
主语：How the book will sell depends on its author. 书销售如何取决于作者本人。
直接宾语：In one's own home one can do what one likes. 在自己家里可以随心所欲。
间接宾语：The club will give whoever wins a prize. 俱乐部将给得胜者设奖。
表语：My question is who will take over president of the Foundation.
我的问题是谁将接任该基金会主席职位。
宾语补足语：She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。
同位语：I have no idea when he will return.
我不知道他什么时候回来。
形容词宾语：I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。
介词宾语：That depends on where we shall go.
那取决于我们去哪儿。
6.2)Wh-从句做主语也常用先行词it做形式主语，而将wh-从句置于句末，例如：
It is not yet decided who will do that job.
还没决定谁做这项工作。
It remains unknown when they are going to get married.
他们何时结婚依然不明。
if,whether从句
7.1)yes-no型疑问从句
从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，因此也分别被称为yes-no型疑问句从句和选择型疑问从句，其功能和wh-从句
的功能相同，例如：
主语：Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。
宾语：Let us know whether / if you can finish the article before Friday.
请让我们知道你是否能在星期五以前把文章写完。
表语：The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。
同位语：They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。
形容词宾语：She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。
介词宾语：I worry about whether he can pass through the crisis of his illness.
我担心他是否能度过疾病的危险期。
7.2）选择性疑问从句
选择性疑问从句由关联词if/whether…or或whether…or not构成，例如：
Please tell me whether / if they are Swedish or Danish.
请告诉我他们是瑞典人还是丹麦人。
I don't care whether you like the plan or not.
我不在乎你是否喜欢该计划。
if和whether的区别：
1、在动词不定式之前只能用whether。如：
I can’t decide whether to stay. 我不能决定是否留下。
2、在whether …… or not 的固定搭配中。如：
I want to know whether it’s good news or not . 我想知道是否是好消息。
3 、在介词后，只能用whether。如：
His father is worried about whether he lose his work .
他的父亲担心是否会失去工作。
4、宾语从句放在句首表示强调时，只能用whether。如：
Whether this is true or not, I really don’t know.
这是否真的，我真的不知道。
5、用if会引起歧义时，只用whether。如：
Could you tell me if you know the answer
这句话有两种意思：“你能告诉我是否知道答案吗？”或“如果你知道答案，请告诉我，好吗？”。如用whether可避免歧义。
形容词性从句
定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词，词组或代词即先行词。定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
含义：在定语的位置上是个句子。
why
关系副词why主要用于修饰表原因的名词（主要是the reason），同时它在定语从句中用作原因状语。如：
We don’t know the reason why he didn’t show up.
我们不知道他为什么没有来。
She didn’t tell me the reason why she refused the offer.
她没跟我讲她拒绝这项工作的原因。
与关系副词when和where不同，why可以换成that或省略。如：
That’s one of the reasons (why, that) I asked you to come.
这就是我请你来的原因之一。
另外，与关系副词when和where可以引导非限制性定语从句不一样，why只能引导限制性定语从句，不能引导非限制性定语从句。如：
他失去工作的主要原因是他喝酒。
误：The main reason, why he lost his job, was that he drank.
正：The main reason why he lost his job was that he drank.
when
关系副词when主要用于修饰表时间的名词，同时它在定语从句中用作时间状语。如：
T here comes a time when you have to make a choice.
你必须作出抉择的时候到了。
Gone are the days when they could do what they liked.
他们为所欲为的日子一去不复返了。
We’ll put off the picnic until next week, when the weather may be better.
我们将把野餐推迟到下星期，那时天气可能会好一点。
注意不要一见到先行词为时间名词，就以为一定要用关系副词when来引导定语从句，同时还要看它在定语从句中充当什么成分——如果在定语从句中用作时间状语，就用when；如果在定语从句中不是用作时间状语，而是用作主语或宾语，那就不能用when，而要用that, which等。如：
Don’t forget the time (that, which) I’ve told you.
不要忘记我告诉你的时间。
关系代词that / which在定语从句中用作动词told的宾语，正因为是用作宾语，所以也可以省略。
where
关系副词where主要用于修饰表地点的名词，同时它在定语从句中用作地点状语。如：
This is the village where he was born.
这就是他出生的村子。
That’s the hotel where we were staying last summer.
这就是我们去年夏天住的旅馆。
Barbary was working in Aubury, where she went daily in a bus.
巴巴拉在奥伯里工作，每天得坐公共汽车去上班。
与前面when的情况一样，注意不要一见到先行词为地点名词，就以为一定要用关系副词where来引导定语从句，同时还要看它在定语从句中充当什么成分——如果在定语从句中用作地点状语，就用where；如果在定语从句中不是用作地点状语，而是用作主语或宾语，那就不能用where，而要用that, which等。如：
He works in a factory that [which] makes TV sets.
他在一家电视机厂工作。
关系代词that / which在定语从句中用作主语。
另外注意，where有时还可用于抽象名词后引导定语从句。如：
We have reached a point where a change is needed.
我们到了必须改一改的地步。
There are cases where the word “mighty”is used as an adverb.
在一些情况下，mighty一词可用作副词。
He got into a situation where it is hard to decide what is right and wrong.
他陷入一种难以分辨是非的局面。
I don’t want a job where I’m chained to a desk all day.
我不想找一份整天坐办公桌前的工作。
高中英语语法定语从句总复习 郴州资兴三中李俊才 定义：用来说明主句中某一名词或代词（有时也可说明整个主句或主句中一部分）而起定语作用的句子叫 作定语从句。 一、关系带词引导的定语从句 1. 关系代词用来指代先行词是人或物的名词或代词 句子成分用于限制从句或非限制性从句只用于限制性从句 代替人代替物代替人或物主语Who which 主语Whom which that 宾语Whose (=of whom) Whose (=of which) that 例１：This is the detective who came from London. 例２：The book which I am reading is written by Tomas Hardy. ２．关系代词的用法 (1) 如果先行词是all, much, anything, something, nothing, everything, little, none等不定代词，关系代词一般只用that，不用which。例如： All the people that are burst into tears.（所有人都迸出眼泪。） (2) 如果先行词被形容词最高级以及first, last, any, only, few, most, no, some, very等词修饰，关系代词常用that,不用which, who，或whom。 (3) 非限制性定语从句中，不能用关系代词that,作宾语用的关系代词也不能省略。 There are about seven million people taking part in the election, most of whom、are well educated. (4) which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分 概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and this 相似，并可以指人。例如： He succeeded in the competition, which made his parents very happy. (5) that可指人或物，在从句中作表语，（指人作主语时多用who）仅用于限制性定语从句中。
宾语从句 1、定义 如果一个句子在复合句中充当一个宾语，那么这个句子就是宾语从句。 2、与简单句的区分 例：*I love teaching.---简单句 *I love what he is doing.---宾语从句 ★宾语从句在句中作及物动词或介词的宾语。 例：*We can learn what we did not know. *I don't agree with what you said at the meeting. 3、语序 宾语从句的语序一般都为陈述句语序。 A.一般情况下，即使是有疑问词，从句仍然是陈述句式。 例：This book will show you what the best CEOs know. 这本书会告诉你最棒的总经理知道什么。 Can you figure out what the poet really means in this poem. 你能理解诗人在这首诗里真正想表达的是什么吗？ B.但个别宾语从句本应用陈述语序，可由于习惯而保持原疑问语序不变。例：I don't know what is the matter with him. I have no idea what was the matter with him. 我不知到他到底怎么了。 关于matter的从句都是疑问语序基本上说I don't know what is wrong也是
对的，可一般来说都是分成两句讲。 I don't know.Is anything wrong？/what's wrong with you. C.特殊类型的宾语从句：当主句中的谓语动词表示认为、建议、猜测时，如think,say,guess,suppose,suggest,say,believe,feel,consider等，这时宾语从句的引导词是who,which,what,when,where,how,why,就不能按照正常语序安排,经常会将这类词放在句首。 例：What course do you say I should take up this semester? Who do you think the public might choose as their favorite singer this year? 4、连接词（引导词） 1）陈述句做宾语（包括肯定句和否定句），连词由that引导。在口语或非正式体中常省略。 例：I don’t know（that）Tom was late again. 2）一般疑问句做宾语，用if／whether引导，if或whether在宾语从句中不作成分。但if和whether在句中的意思是“是否”。 例：I want to know if(whether)he lives there. He asked me whether(if)I could help him. ★if/whether的区别 A.从句放在句首表示强调时，只能用whether； B.及物动词discuss后的宾从，只用whether； C.if与whether都可以与or not连用，但后面紧跟着or not时只能用whether； D.介词后的宾从只用whether; E.后接动词不定式时用whether. 3）特殊疑问句做宾语，用特殊疑问词连接（宾语从句缺什么成分就选择相应的特殊疑问词）。
高中英语语法系列：定语从句 知识要点 1.关系代词和关系副词的选用 2.限制性定语从句和非限制性定语从句的区别 3.几组的关系词特殊用法 一、定义：在复合句中，修饰名词或代词的从句叫做定语从句。 The happy man who lives next to me sells vegetables. You must do everything that I do. 被定语从句修饰的词，叫先行词。比如上面两句中的man和everything. 引导定语从句的词，叫关系代词和关系副词。比如who,whom,that,which,wh ere,when,why等 关系词三重作用：①连接主从句；②指代先行词；③在定语从句中担任句子成分。 The man who lives next to me sells vegetables. 该句中，who lives next to me是定语从句，修饰先行词the man，“who”是引导定语从句的关系词，代替先行词the man，在定语从句中作主语。 二、关系词 引导定语从句的关系代词有who,whom,which,that,whose,as等和关系副词w here,when,why等。关系代词和关系副词在定语从句中担任句子成分。
1.用关系代词that,which,who,whom引导的定语从句 who指人，用作主语 whom指人，用作宾语 which指物，用作主语、宾语皆可 that指人和物，用作主语、宾语皆可 The teacher who visits our school today is from Guangzhou. Mrs Read is the person whom you should write to. They planted some trees which didn’t need much water. The fish(which)we bought this morning were not fresh. A plane is a machine that can fly. The noodles(that)I cooked were delicious. 2.用关系代词whose引导的定语从句： 先行词既可指人，也可指物，一般译为“谁的”“什么东西的”，请看例子 The room whose window faces south is mine. 3.用关系副词when、where、why引导的定语从句 (1)when在从句中作时间状语 October lst,1949is the day when(=on which)the People’s Republic of Chin a was founded. (2)where在从句中作地点状语 I recently went to the town where(=in which)I was born. (3)why在从句中作原因状语 The reason why(=for which)he was late was that he missed the train.
（1）表语从句 1．定义：用作表语的从句叫做表语从句。 2．构成：关联词+简单句 3．引导表语从句的关联词的种类： (1) 从属连词that。如： The trouble is that I have lost his address. 麻烦是我把他的地址丢了。 (2) 从属连词whether, as, as if。如： He looked just as he had looked ten years before. 他看起来还与十年前一样。 The question is whether they will be able to help us. 问题是他们是否能帮我们。 注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如： All this was over twenty years ago, but it's as if it was only yesterday. gh能跟表语从句的谓语动词一般为系动词be, seem, look等。如： It looked as if it was going to rain. 看起来天要下雨了。 连接副词 where, when, how, why。 如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。 The question is how he did it. 问题是他是如何做此事的。 That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 解释： 1．连词because可引导表语从句。如： I think it is because you are doing too much. 我想这是因为你做得太多。 2．在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如： My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。（2）主语从句 1．定义：用作主语的从句叫做主语从句。 2．构成：关联词+简单句 3．引导主语从句的关联词有三类： (1) 从属连词that。如：That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们确是亲姐妹，她们的脸型很相似。 (2) 从属连词whether。如： Whether he’ll come here isn’t clear. 他是否会来这里还不清楚。 (3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever 连接副词 where, when, how, why。如： What she did is not yet known. 她干了什么尚不清楚。 How this happened is not clear to anyone. 这事怎样发生的，谁也不清楚。 Whoever comes is welcome. 不论谁来都欢迎。 Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。 解释： 1．主语从句能用it作形式上的主语。常以it作形式主语的句型有： A. It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that从句。如： It is certain that she will do well in her exam. 毫无疑问她考试成绩会很好。 It is probable that he told her everything. 很可能他把一切都告诉她了。 B. It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that
状语从句一． 二．分类：
adv.+that （如此……以致） so that （结果……） such+n.+that （如果……以致） that （所以，因此） 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） 三． 四． 各种状语从句的简化方法：
1． 2．以after和before引导的状语从句的主语若与主句主语一致时，从句等于after/before+doing sth. 作状语。 例：After she sang，she left the rich man's house．= After singing，she left the rich man's house．3． 4．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． 5． 6．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． 7． 8．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．9． 10．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． 11．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． 12．在时间、原因、条件等状语从句中，若从句和主句主语不一致时，可简化为分词复合结构作状语。有时也可简化为“with/without名词或代词十分词(短语)”形式作状语。 例：When the film start appeared, the children got exited．= The film start appearing，the children got exited． If all the work is done, you can have a rest．= With all the work done，you can have a rest． Nothing can live if there is no air．= Nothing can live without air．

高考高中英语语法宾语从句考点总结 宾语从句是指一个句子在复合句中作主句的宾语，它是使用最广泛的复合句之一，它也是中考的经常考查的知识点之一。宾语从句的使用主要注意五点： 考点一注意正确使用引导词 宾语从句的引导词的使用，分为以下三种情况： （1）如果用一个陈述句来充当主句的宾语，则由that 引导（that在口语或非正式文体中常省略）。如： He said (that) he would like to see the headmaster.他说他想见校长。 She said (that ) she would leave a message on his desk.她说她将在他的桌上留个便条。 Mr Wu said (that) he was interested in taking photos.吴先生说他对摄影很感兴趣。 （2）如果用一个特殊疑问句来充当主句的宾语，则由连接代词who, whom, whose ,what, which或连接副词when, where, why, how引导。如： I don’t know where he is from.
我不知道他来自何方。 The chil dren didn’t know who Father Christmas is.孩子们不知道谁是圣诞老人。 He asked me why I was late for the meeting. 他问我为什么迟到。 Could you tell me how I can get to the railway station?你能告诉我去火车站的路怎么走。 （3）.如果用一个一般疑问句来充当主句的宾语，则由连词if或whether引导。如： She asked me if she could borrow these books. 她问我她能否借这些书。 Could you tell me if there are any good museums in Newtown? 你能告诉我新镇是否有一些好的博物馆吗？ I am not sure if he will come to my birthday party. 我不太确信他是否会参加我的生日聚会。 考点二注意正确使用时态 当主句谓语动词是一般现在时时，从句可以根据实际情况使用相应的时态；当主句是一般过去时时，从句根据实际情况用过去时态的某一种。
2021届高中英语新高考语法基础版一轮复习讲义（30） 表语从句知识点整理总结 01 表语从句的概念和引导词 表语从句是指一个句子充当主系表结构中的表语而成的从句。它的构成和其他名词性从句一样。 和宾语从句、主语从句的类似，表语从句的引导词也分为如下三类： a. 陈述句做表语从句，用that引导。如： T h e p ro bl e m i s th a t t h e y do n't f o l l o w m y a d vi ce. 问题在于他们不听我的劝告。 注意：表语从句中的that不可以省略。 b. 一般疑问句做表语从句，一般用whether引导，不用if。如： The key is whether the boss will give us the chance to participate in the project. 关键是老板是是否会让我们参与这个项目。 c. 特殊疑问句做表语从句，用what/who等特殊疑问词引导。如： The problem is when we will receive the fund. 问题在于我们何时能收到这笔资金。 02 常见表语从句的句型
和主语从句类似，表语从句也有一些常见的结构化的句型，具体包括以下几类： a. 名词+is +表语从句。 这些名词有表示事实的truth, fact，表示观点的idea, advice, problem, question, thought, feeling, plan, suggestion等。如：The fact is that he is the best teacher in the entire school. 事实是，他是全校最好的老师。 The question is when the rescue team will arrive here. 问题是救援小组何时能到这里。 当然，名词这里也可以是主语从句。如： What I want to know is who will be elected as the monitor in the new term. 我想知道的是新学期谁会被当选为班长？ 注意：当名词是suggestion/order/request等表示主张和建议时，表语从句要用should+do的虚拟语气，其中should可以省略。 b. It/This/That is because/why从句。 如： That is why he was sent to the mental hospital. 这就是他被送往精神病医院的原因。
