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。
一、构成
引导词:
连接词：that（无意义，在从句中不作成分）、if、whether（“是否”的意思，在从句中不作成分）。
连接代词：what、wh、whm、which、whse等（在从句中作主语、宾语、表语、定语）。
连接副词：when、where、why、hw（在从句中作状语）。
语序：要用陈述句语序，即“引导词 + 主语 + 谓语 + 其他成分”。
二、用法
主语从句
定义：在复合句中作主语的从句。例如：That he will cme is certain.（“That he will cme”是主语从句，在句中作主语，表示“他要来”这件事是确定的）。
注意：为避免头重脚轻，常用it作形式主语，把主语从句放在后面。比如：It's a pity that yu missed the party.（真正的主语是“that yu missed the party”）。
宾语从句
定义：在复合句中作宾语的从句。例如：I think (that) yu are right.
（“that yu are right”是宾语从句，作think的宾语）。
位置：在及物动词、介词或某些形容词（如sure、glad等）后。
表语从句
定义：在复合句中作表语的从句，位于系动词之后。
例如：The prblem is wh can help us.（“wh can help us”是表语从句，跟在系动词is之后，
说明问题是“谁能帮助我们”）。
同位语从句
定义：用于解释说明前面某一名词的内容。
例如：The news that ur team wn the game made us excited.
（“that ur team wn the game”是同位语从句，用来解释说明news的内容，
即“我们队赢了比赛”这个消息）。
特点：常跟同位语从句的名词有news、fact、idea、prmise等。
Grammar主语从句
主语从句的用法精讲：
一、主语从句
1、定义：在复合句中充当主语的从句叫作主语从句。主语从句可以直接放在句首，
也可以用形式主语it代替,将主语从句放在句末。
2、判断一个句子是否是主语从句的诀窍：
首先，看句子结构。如果一个从句在复合句中充当主语，那它就是主语从句。例如在句子
“What he said is very imprtant.”中，“What he said”这个从句在整个句子中作主语，所以它是主语从句。
其次，观察从句位置。主语从句通常位于句首，但有时为了避免句子头重脚轻，会用it作形式主语，
将主语从句后置。像“It's a pity that yu can't cme.”这里真正的主语是“that yu can't cme”，它是主语从句，被后置了，而it是形式主语。
最后，留意引导词。主语从句常由一些特定的引导词引导，如that（无实际意义）、whether（是否）、
what（……的事物）、wh（谁）、when（什么时候）、where（什么地方）、why（为什么）、hw（怎样）等。看到这些引导词引导的从句在句首作主语或者在形式主语it后作真正主语，就可以判断是主语从句。
例如“Whether we will have a picnic depends n the weather.”中“Whether we will have a picnic”
就是主语从句。
二、主语从句的结构
1、主语从句的引导词
主语从句中选择连接词的方法：
（1)根据连接词在从句中所作的语法成分。
(2)根据连接词在从句中的意义。
2、it作形式主语
为了保持句子平衡，常把主语从句后置，而用形式主语it代替。it作形式主语时常用于以下句型：
【特别提醒】
（1）在“It+ be+过去分词+主语从句”结构中，过去分词若为suggested/rdered/required/advised等， 主语从句中的谓语用“(shuld）d”。
(2）在“It+ be+形容词+主语从句”结构中，若形容词为imprtant/necessary/strange等，主语从句中的谓语用“(shuld)d”。
二、主语从句中应注意的问题
1、从句要用陈述语序
2、主谓一致
（1）从句作主语时，主句的谓语一般用单数形式。
what 引导主语从句时，有时主句谓语动词应与主句中作表语的名词保持一致。
如果由and连接两个或两个以上的主语从句作主语时，谓语动词用复数；
由两个或多个连接词 引导一个主语从句时，谓语动词用单数。
3、单个主语从句作主语,谓语动词通常用单数形式
that引导的主语从句:that在从句中不作任何成分,没有词义,只起连接作用,且不能省略
(1)that置于句首的主语从句。
the cllege will take in mre students is true.
这所大学要招收更多的新生是真的。
it作形式主语,that引导的主语从句后置。
①It+be+adj.+that 从句。
It's bvius that they badly need help.很明显,他们急需援助。
②It+be+名词(短语)+that从句。
rder, is a pity that yu missed the film.
你没看这部电影太可惜了.
③It+be+过去分词+that从句,常用句型如下:
It is said that...据说……
It is reprted that...据报道.…
It is suggested that...据建议……
It is well-knwn that... 众所周知
It is hped that...人们希望.…
is suggested that we shuld set ut at dawn.据建议我们应该黎明时出发。
It is reprted that the supplies will be delivered t the area tmrrw.
据报道补给品明天会运往该地区。
It is said that n ne will be interested in buying such an expensive car.
据说没人有兴趣买这样一辆昂贵的车。
④It+不及物动词(短语)+that 从句,常用于此句式的动词(短语)有形式主
seem, appear,matter(有关系),happen(碰巧),ccur t sb.(某人突然想到),turn ut(结果是)等。
seems that he has seen the film.
似乎他已经看过这部电影了。
It happened that the tw cheats were there.碰巧这两个骗子在那里。
It turned ut that he was the ne wh made the mistake
主语从句精准考点练习题精讲：
1. _______ yu dn't like him is nne f my business.
A. What B. Wh C. That D. Whether
答案：C。解析：“____ yu dn't like him”是主语从句，从句意思完整，不缺成分，用that引导，在句中无实际意义。
2. It remains a mystery _______ the ancient Egyptians built the pyramids.
A. hw B. that C. which D. what
答案：A。解析：这里it是形式主语，真正的主语从句是“____ the ancient Egyptians built the pyramids”，从句中缺少方式状语，意思是“古埃及人是怎样建造金字塔的”，所以用hw。
3. _______ has caused this severe accident is still a mystery.
A. What B. That C. Hw D. Where
答案：A。解析：“____ has caused this severe accident”是主语从句，从句中缺少主语，“什么导致了这场严重的事故”，用what。
4、_______ makes this bk s extrardinary is the creative imaginatin f the writer.
A. That B. What C. Wh D. Which
- 答案：B
- 解题思路：分析句子结构，“_______ makes this bk s extrardinary”是主语从句，在这个从句中，缺少一个表示“什么”的词作主语，因为从句的谓语动词是“makes”，需要一个能充当主语的成分。“that”在主语从句中无实际意义，且不能充当成分；“wh”表示人，不符合题意；“which”表示“哪一个”，也不符合语境。而“what”有“……的东西/事情”的意思，可以在从句中充当主语，所以应该选B。
5、It is still under discussin _______ the ld bus statin shuld be replaced with a mdern htel r nt.
A. whether B. when C. which D. where
- 答案：A
- 解题思路：这是一个含有主语从句的句子，“it”是形式主语，真正的主语是后面的从句。从句中有“r nt”，表示“是否”，在主语从句中，表示“是否”且能与“r nt”搭配的引导词是“whether”，“when”表示时间，“which”表示“哪一个”，“where”表示地点，都不符合语境，所以选A。
二、用适当的引导词填空
1. _______ will win the game is still unknwn.
答案：Wh。解析：“____ will win the game”是主语从句，从句中缺少表示人的主语，“谁会赢得比赛”，所以填Wh。
2. _______ he left withut saying gdbye made me angry.
答案：That。解析：“____ he left withut saying gdbye”是主语从句，从句意思完整，用that引导。
三、翻译句子并指出主语从句部分
1. 他什么时候回来对我们的计划很重要。
答案：When he will cme back is very imprtant fr ur plan. 主语从句部分是“When he will cme back”。
2. 她所说的可能是真的。
答案：What she said might be true. 主语从句部分是“What she said”。

Grammar宾语从句
一、宾语从句的用法精讲
在复合句中作主句宾语的从句叫宾语从句。宾语从句可分为动词的宾语从句、介词的宾语从句和形容词的宾语从句。引导宾语从句的词有连词：that, whether, if；连接代词：wh, whm, whse, what, which, whever, whmever, whatever, whichever；连接副词：when, whenever, where, wherever, hw, hwever, why。宾语从句必须用陈述句语序，即:连接词+主语+谓语+其他成分
（一）判断一个句子是否是宾语从句诀窍：
首先看句子结构，在主从复合句中，如果从句在及物动词、介词或者某些形容词之后作宾语，
那这个从句很可能是宾语从句。例如，“I knw (that) he is a gd student.”，其中“knw”是及物动词，
“he is a gd student”这个从句作“knw”的宾语。

其次，宾语从句一般有连接词来引导，像that（可省略）、if、whether、what、wh等。例如，“She asked me if I culd help her.”，“if”引导的从句在“asked”这个动词后作宾语。
（二）结构：
1. 连词that, whether, if引导的宾语从句
that, whether, if在宾语从句中不作成分，只起连接作用。that无意义，可以省略；whether/if意为“是否”，不可省略。
He said (that) he wuld help us. 他说他会帮助我们。
I think (that) yu are right. 我认为你是对的。
We dubt whether/if he will cme. 我们怀疑他是否要来。
速记口诀：
采用"缺什么用什么"的原则,什么意义都不缺用 that,表“是否"用whether/ if。
特别提醒：
dubt用法总结:
①作动词否定句:that肯定句:whether/if
②作名词一肯定句:whether
否定句:that
is n dubt that he will becme cnfident.
毫无疑问他会变得自信. I dn't dubt that yu have the ability t take charge f the whle firm.我相信你有能力掌管整个公司。
2. 连接代词引导的宾语从句
wh, whm, whse, what, which, whever, whmever, whatever, whichever等引导宾语从句，在宾语从句中可以作主语、宾语、表语或定语，有具体的意思且不能省略。
D yu knw wh they are waiting fr? 你知道他们在等谁吗？
I dn’t knw whse bk this is. 我不知道这是谁的书。
Pay attentin t what the teacher said. 注意老师所说的话。
Give a reading list t whever cmes. 给所有来的人一份阅读书目。
I will take whichever bk interests me. 我愿买任何让我感兴趣的书。
3. 连接副词引导的宾语从句
when, whenever, where, wherever, hw, hwever, why等引导宾语从句，在宾语从句中可以作状语，有具体的意思且不能省略。
I dn’t knw when we will meet again. 我不知道我们何时才能再见面。
D yu knw why he was late? 你知道他为什么迟到吗？
I dn’t mind hwever late yu cme. 我不介意你来得多么晚。
4. it作形式宾语，代替宾语从句
①feel, find, think, cnsider, believe, make等后有宾语补足语时，常用it作形式宾语，而将that从句后置。（即结构：feel/find/think/cnsider/believe/make…+it+OC+that…）
We feel it ur duty that we shuld make ur cuntry a better place.
我们觉得使我们的国家成为一个更好的地方是我们的责任。
We all find it imprtant that we shuld learn English well. 我们都发现学好英语是重要的。
He made it quite clear that he preferred cffee t tea. 他很明确地说他喜欢咖啡胜过茶。
I think it best that yu shuld seek fr a new slutin t the prblem.
我认为你最好寻找一个解决该问题的新办法。
②有些动词或短语后一般不直接接宾语从句，需在宾语从句前加it作形式宾语，这类动词有hate, like, dislike, lve, hide, hear, take, see t, depend n, rely n, cunt n, enjy, appreciate, answer fr, feel like, be fnd f等。（即结构：hate/like/dislike…+it+宾语从句）
I hate it when yu lk at me like that. 我不喜欢你看我的样子。
I will appreciate it if yu can help me. 如果你能帮助我，我将不胜感激。
Please see t it that yu bring enugh mney when yu g ut. 出门时请务必带足够的钱。
They will answer fr it that the cmputer is reliable. 他们愿意保证这台电脑是可靠的。
5. 宾语从句可以跟在及物动词（短语）后面，也可以跟在某些介词后面，还可以跟在某些形容词的后面。
He says that he cmes frm Lianyungang. 他说他来自连云港。
We always mean what we say. 我们向来说话算话。
Our success depends n hw well we can cperate with ne anther.
我们的成功取决于我们互相之间合作得如何。
He ges t the library every day except when it is raining.
除了天下雨外，他每天都去图书馆。
I like the bk in that it is mre interesting. 我喜欢这本书因为它更有趣。
I am interested in hw we use cmputer. 我对如何使用电脑感兴趣。
I’m sure that they will win. 我确信他们会赢。
I’m afraid that he is ill. 恐怕他病了。
6. 宾语从句的否定转移
若主句的主语为第一人称且为一般现在时，主句的谓语动词是think, believe, imagine, suppse, cnsider, expect, fancy, guess等时，从句的否定一般要转移到主句上来。其反意疑问句的主语要与宾语从句中的主语保持一致，附加问句用肯定形式。
I dn’t think yu are right. 我认为你不对。
I dn’t believe that he will keep his wrd. 我认为他不会守信的。
We dn’t suppse that it is his fault, is it? 我们认为那不是他的过错，是不是？
7. 复杂的特殊疑问句（又称双重疑问句）
在某些宾语从句中，宾语从句的连接代词或连接副词常被移到主句之前，构成特殊疑问形式，其结构为：特殊疑问词+d yu think+宾语从句的其他部分（用陈述语序）？常见的用于此结构的动词有think, believe, imagine, suppse, cnsider, expect, fancy, guess, hpe, say等。
What d yu think we will d next? 你认为我们下一步该怎么办？
Wh d yu guess is n duty tday? 你认为今天谁值日？
Hw d yu say they will g t Beijing? 你说他们将怎样去北京？
8. 使用宾语从句使用诀窍：
①在宾语从句中连词that常省略，但在以下几种情况下不可以省略。在某些动词如agree, argue, hld, bserve, remark, state等之后that习惯上不省略；形式宾语it后that不能省略；动词和that从句中间有插入成分时不能省略；介词后面有that不能省略；有两个或两个以上的宾语从句并列时，第一个that可以省略，其余的都不能省略。
He remarked that it was getting late. 他说天色渐晚了。
We hld that he is wrng. 我们认为他错了。
He made it quite clear that he preferred cffee t tea. 他很明确地说他喜欢咖啡胜过茶。
They will answer fr it that the cmputer is reliable. 他们愿意保证这台电脑是可靠的。
They tld us nce again that the situatin was serius. 他们又一次告诉我们说形势很严重。
The bus is empty except that there is an ld lady in it.
除了有位老太太外，那辆公共汽车是空的。
I like the bk in that it is mre interesting. 我喜欢这本书因为它更有趣。
I think (that) he needs sme help and that we shuld help him.
我认为他需要帮助，我们应该帮助他。
②在宾语从句中连词whether, if常可互换，但在以下几种情况下不可以互换。宾语从句为否定句时，只能用if；在介词后面时，只能用whether；紧跟r nt时，只能用whether；后接不定式时，只能用whether；某些动词（discuss, dubt, leave, put）后只能用whether；宾语从句位于句首时，只能用whether；在引起歧义的情况下，应用whether。
I care if he desn’t cme. 我介意他是否不来。
I’m nt sure f whether it will rain. 我不能确定天是否下雨。
I dn’t care whether r nt she will attend the meeting. 我根本不关心她是否参加会议。
I haven’t decided whether t g there by bus. 我还没有决定是否做公交车去那儿。

Whether he can finish the wrk r nt, I can’t say. 他是否能完成这项工作，我说不准。
Please let me knw whether yu need my help. 请让我知道你是否需要我帮忙。
③在“坚持、命令、建议、要求”等动词后的宾语从句中，要用虚拟语气，即shuld+动词原形，shuld可以省略。常见的动词有：insist; rder, cmmand; advise, suggest, prpse, recmmend; demand, require, desire, request等。（即：一坚持二命令四建议四要求。）
He insisted that he (shuld) be sent t Tibet. 他坚决要求被派往西藏。
The fficer rdered that the sldiers (shuld) start at nce.
那位军官命令战士们应该马上动身。
④宾语从句的时态。当主句中的谓语是现在时或将来时时，从句中的谓语不受主句谓语时态的影响，可以根据需要使用任何时态; 当主句谓语是过去时态时，从句的时态用相应的过去时态；若从句叙述的是客观真理或事实时，从句的时态则用一般现在时。
She says that she wrks every day. 她说她每天工作。（从句用一般现在时）
She says that she will leave fr Shanghai tmrrw.
她说明天她要动身去上海。（从句用一般将来时）
She says that she has never been t Munt Emei.

Grammar表语从句
表语从句的用法精讲
定义：在句中充当表语的从句(即放在系动词后面)叫做表语从句。
一、判断一个句子是表语从句诀窍：
首先，表语从句在主从复合句中位于系动词之后，像be动词（am、is、are等）、感官系动词（feel、lk、smell等）、变化系动词（becme、get等）之后，对主语进行解释、说明或者描述。例如，“The prblem is that we dn't have enugh time.”，句子中的“is”是系动词，“that we dn't have enugh time”是表语从句，用于说明“问题”是什么。

其次，表语从句也有连接词引导，如that、whether、as if、because等。例如，“It lks as if it's ging t rain.”，“as if”引导的表语从句用于说明主语“it”（天气）呈现出的状况。
二、结构：
1、 that引导的表语从句
that为从属连词，不充当任何成分，无词义，只起引导作用，在非正式语体中that也可以省略，表示确定的陈述，位于从句句首。
My advice is that we shuld set ff earlier.
The answer is they didn’t call me Jim.
2 、 whether引导的表语从句
whether为从属连词，不充当任何成分，有词义，只起引导作用，在非正式语体中是可以省略的，表示不确定的陈述，位于从句句首。
The questin is whether we shuld accept his invitatin.
3、 疑问词或连接词引导的表语从句
疑问词或连接词为代词或副词，充当成分，有词义，一般不省略，表示疑问或陈述，位于从句句首。
That’s why we put ff the meeting.
注1：reasn后跟表语从句时，一般只用that而不用because/why引导。
eg:The reasn why he came late yesterday was that he was ill at hme.
4、从属连词as/as if/as thugh/because/why也可引导表语从句。
Things were nt as they seemed t be.
It lked as if it was ging t rain.
That’s because he didn’t wrk hard fr the cmpany.
That’s why I asked fr a week’s leave.
三、使用虚拟语气的表语从句
在表示建议、劝告、命令含义的名词后的表语从句，谓语动词需用“shuld+动词原形” 表示，shuld可省略。常见的词有：advice，suggestin，rder，prpsal，plan，idea等
e.g. My suggestin is that we (shuld) start early tmrrw.
四、常用句型：
主语+be+表语从句
①代词+be+表语从句
It/This/That +be+表语从句
eg. This is what I want. 这就是我想要的东西。
That is because I lack mney.那是因为我缺钱。
②名词+be+表语从句
eg. Knwledge is what I lng fr.知识就是我渴望的东西。
The reasn was that she gt up late.
有改错题时：The reasn was because she gt up late. (because→that)
=That is because she gt up late.
③名词+定语从句+be+ 表语从句
eg. Knwledge that is useful is what I lng fr. 有用的知识就是我渴望的东西。
④主语从句+be+表语从句
eg. What is useful is what I lng fr. 有用的东西就是我渴望的。
What I hpe is that yu can accept my invitatin.

Grammar同位语从句
同位语从句的用法精讲
定义：同位语从句是对中心词具体内容的解释和说明。中心词一般是news, fact, idea, infrmatin,
cnclusin, prblem, suggestin, evidence, belief, prmise等抽象名词。
特别提醒：
分隔式/间隔式同位语从句：若主句的谓语较短，同位语从句较长，通常把同位语从句后置，从而构成分隔式/间隔式同位语从句。这时，要根据语意并仔细分析句子结构，才能做出准确判断。
When the news came that the war brke ut, he decided t serve in the army.
一、判断一个句子是同位语从句诀窍：
首先看位置，同位语从句通常紧跟在抽象名词（如fact、idea、news、hpe、belief、thught等）之后，用于对这个名词的内容进行解释说明。例如，“The fact that he wn the first prize made his parents very happy.”，从句“that he wn the first prize”是对“fact”的具体内容的阐释。
其次看引导词，同位语从句常用that引导，在从句中不充当句子成分，只起连接作用。不过也有用when、where、why、whether等引导的情况。比如，“I have n idea when he will cme
二、用法
1、 that引导的同位语从句
that为从属连词，引导同位语从句时，that不充当任何成分，无词义，只起引导作用，一般不省略，
表示确定的陈述。
eg: The news that they wn the match is true.
2、 whether引导的同位语从句
whether为从属连词，不充当任何成分，有词义，只起引导作用，一般不省略，表示不确定的陈述。
eg: The questin whether it is right r wrng depends n situatin. He was trtured by the dubt whether he wuld accept their presents.
3、疑问词或连接词引导的同位语从句 疑问词或连接词为代词或副词，充当成分，有词义，一般不省略，表示疑问或陈述。
eg: I have n idea what has happened t him.
三、常见的同位语从句高级句型
(1) There is n denying that + 主语 + 谓语……(不可否认的……)
e.g. There is n denying that the qualities f ur living have gne frm bad t wrse.
(2) There is n dubt that 从句(毫无疑问的……)
e.g. There is n dubt that ur educatinal system leaves smething t be desired.
注意： There is sme dubt+ when/whether/what/where/wh…不可以用that
四、同位语从句和定语从句的区别
(1)从句的作用不同：
①定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that不但起连接作用，而且在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。
②同位语从句对中心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.
e.g. We expressed the hpe that they had expressed. (定语从句)
We expressed the hpe that they wuld cme t China again. (同位语从句)
(2)被修饰的词不同：
①定语从句的先行词是任何名词都可以；
②同位语从句的中心词只能是抽象名词（无法用化学符号表示），常见 news, truth, fact, idea, infrmatin, cnclusin, prblem, suggestin, evidence, belief, prmise等。
(3)引导词不同：
定语从句的引导词没有 what, hw, whether等，而且that充当从句的成分；同位语从句可以用 what, hw, whether等，同事that不充当从句的成分。
Eg. I knw the man that is under the tree.(定语从句)
I have a questin whether the future will be better.
We heard the news that ur team had wn．
