名词性从句用法归纳
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）。
名词性从句在复合句中能担任:主语、宾语、表语、同位语、介词宾语等。
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、引导名词性从句的连接词
引导名词性从句的连接词可分为三类：
1、从属连词（5个）：
（1）that无词义，在从句中不做成分，在宾语从句或表语从句中that有时可以省略
（2）whether，if 有词义，在从句中不做成分（whether，if均表示“是否”之意，表明从句内容的不确定性）不可以省略
（3）as if, as though （均表示“好像”，“似乎”之意）在从句中不做成分
2、连接代词（9个）：what, whatever, who, whoever, whom, whomever, whose, which, whichever，有词义，在从句中做成分，不可以省略（who what which 在从句中做主语、宾语、其中what 指代没有范围的事物，which指代有范围的事物，表“选择哪一个”whom做宾语whose 做定语）
3、连接副词（7个）：when, where, how, why, whenever, wherever, however有词义，在从句中做状语，不可以省略
4、that省略的情况：
（1）定语从句中做宾语
（2）that引导宾语从句时
（3）that引导表语从句时
（4）主语从句中it做形式主语，that从句置于句末时
5、that不可省略的情况：
（1）定语从句中做主语
（2）由that引导主语从句放句首时
（3）that引导同位语从句时
（4）宾语从句中i it做形式宾语，真正的that宾语从句中that不可以省略
ii 一个句子有两个或多个并列的宾语从句时，引导第二个和以后几个句子中的that不可以省略
iii 与动词相隔的宾语从句，不可以省略
iv that引导的宾语从句放在句首时，不可以省略
二. 主语从句
1、主语从句：作句子主语的从句叫主语从句。
主语从句通常由下列词引导：
1）从属连词that，whether 等；
2）连接代词what，who，which，whatever，whoever，whom 等；
3) 连接副词how，when，where，why 等。
2、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。注：whom、who指人，what指物，whatever，whoever表示泛指意义。例如：
What he wants to tell us is not clear.
Who will win the match is still unknown.
It is known to us how he became a writer.
Where the English evening will be held has not yet been announced.
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：（1）It + be + 名词+ that从句：It is a fact that 事实是
It is an honour that 非常荣幸
It is common knowledge that …是常识
It is a pity that 遗憾……
（2）It + be + 动词的过去分词+ that从句:
It is said that 据说
It is reported that 据报道
It has been proved that 已经证明
It is believed that … 人们认为
It is supposed that… 据猜测
（3）It + 不及物动词（vi）+ that 从句：
It seems that 似乎
It happened that 碰巧
It appears that 似乎
（4）It + be + 形容词+ that从句
It is natural that… 很自然…
It is strange that… 奇怪的是…
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 sugges ted (requested, proposed, desired, etc.) that…
3、It 作形式主语和it引导强调句的比较
①It 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。
②it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 引导，被强调部分指人时也可用who/whom。例如：
a) It is a pity that you didn’t go to see the film.
b) It doesn’t interest me whether you succeed or not.
c) It is in the morning that the murder took place.（强调句型）
d) It is John that broke the window.（强调句型）
4、注意：since, if 不能引导主语从句，但当it做形式主语，主语从句放在句末时，if, whether 均可
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居于复合句句首。
（2）It is said /reported…结构中的主语从句不可提前。例如：
正确表达：It is said that President Jiang will visit our school next week.
错误表达：That President Jiang will visit our school next week is said.
（3）It happens/occurs…结构中的主语从句不可提前。例如：
正确表达：It occurred to him that he failed in the examination.
错误表达：That he failed in the examination occurred to him.
（4）It doesn’t matter how/whether …结构中的主语从句不可提前。例如：
正确表达：It doesn’t matter whether he is wrong or not.
错误表达：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。例如：
正确表达：Is it likely that it will rain in the evening?
错误表达：Is that will rain in the evening likely?
6、what 与that 在引导主语从句时的区别
what 引导主语从句时在句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。例如：
a) What you said yesterday is right.
b) That she is still alive is a consolation
三、表语从句
表语从句：在复合句中，位于系动词之后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，表语从句位于连系动词后，有时用as if引导。
可以接表语从句的系动词有be ,look , remain（保持）, seem等
常用的还有the reason is that … It is because … It appears/seems that…
It happens that… It turns out that…（结果是...）等结构
由从属连词，连接代词，连接副词引导，其中that常常可以省略
由as if，as though 引导It looks as if… It seems as if…
why, because 都可以引导表语从句，但why强调结果，because强调理由
当主语为suggestion, order, requirement, advice, request, demand 等这类名词时，表语从句用虚拟语气（should）do
if不能引导表语从句
注意：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。
四、同位语从句
1、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，that不可以省略
由whether引导，不可用if
2、可用于同位语从句的名词有belief、advice、demand、doubt（怀疑）、possibility、though、proposal、case、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.
I have no idea when he will come back home.
The thought came to him that Mary had probably fallen ill.
3、在no idea后用wh-疑问词引导
4、同位语从句与定语从句的区别
(1) 定语从句中的that既代替先行词，同时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，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。例如：
1) 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。）（第一个that引导的从句是定语从句，that在从句中作宾语）
2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。）（同位语从句，that在句中不作任何成分）
五、宾语从句
宾语从句：名词从句用作宾语的从句叫宾语从句。由从属连词、连接代词、连接副词引导。
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.
We must never think (that) we are good in everything while others are good in nothing.
注意：在demand、order（命令）、suggest、decide、insist（坚持）, desire, urge，advice，propose，require，request, command（命令）, 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.
The commander ordered that troops (should) set off at once.
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.
She always thinks of how she can work well.
She will give whoever needs help a warm support.
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.
Everything depends on whether we have enough money.
I wonder whether he will come or not.
Can you tell me whether to go or to stay?
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：
I know (that) he studies English every day. （从句用一般现在时）
I know (that) 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）
I know (that) he has studied English since 1998. （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，guess, expect, fancy, consider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 believe he will do so. 我相信他不会这样做。
6、后面不能接that从句的动词有：condemn谴责，判刑force强迫take拿走forgive 原谅dislike不喜欢refuse拒绝let like love help admire羡慕allow celebrate cause
注：以上动词后不能接that从句，但可以用不定式，动名词做宾语。
六、whether与if 均为"是否"的意思。
但在下列情况下，只可用whether：
1. whether引导主语从句并在句首时，只能用whether，当it做形式主语，主语放句首时，whether，if均可
eg:whether he can come to the party on time depends on the traffic
2. 引导表语从句
eg:The question is whether we can get in touch with her
3. whether从句作介词宾语
e.g:It depends on whether he will come.
4.if与whether都可以与or not 连用，但后面紧跟or not 时只能用whether
We didn't know whether or not she was ready.（此时只能用whether）
I wonder whether/if the news is true or not.（此时则二者都可以用）
5. 引导同位语从句
Whether he will come is not clear.
6.后接不定式时
Eg I don’t know whether to go.
7.在discuss后只能用whether
注意：（1）大部分连接词引导的主语从句都可以置于句末，用it充当形式主语。It is not important who will go.
It is still unknown which team will win the match.
（2）whether从句中不能有否定式，而if可以
I don’t care if he doesn’t come.
七、名词性that-从句
（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.事实是近来谁也没有见过他。
同位语：The fact that he has not been seen recently disturbs everyone in his office.
近来谁也没有见过他，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.
2）That-从句作主语通常用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……
I t occurred to me that…我突然想起……
八、名词性wh-从句
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.
直接宾语：In one's own home one can do what one likes.
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.
宾语补足语：She will name him whatever she wants to.
同位语：I have no idea when he will return.
形容词宾语：I'm not sure why she refused their invitation.
介词宾语：That depends on where we shall go.
2）Wh-从句作主语也常用先行词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.
It remains unknown when they are going to get married.
九、if, whether引导的名词从句
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.
宾语：Let us know whether / if you can finish the article before Friday.
表语：The point is whether we should lend him the money.
同位语：They are investigating the question whether the man is trustworthy.
形容词宾语：She's doubtful whether we shall be able to come.
介词宾语：I worry about whether he can pass through the crisis of his illness.
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.
I don't care whether you like the plan or not.
if和whether的区别：
1、在动词不定式之前只能用whether 。如：
例8 I can’t decide whether to stay.
2、在whether …… or not 的固定搭配中。如：
例9 I want to know whether it’s good news or not .
3 、在介词后，只能用whether。如：
例10 His father is worried about whether he lose his work .。
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.
（例11 Whether they can finish the work on time is still a problem . 他们是否能准时完成这项工作还是个问题。－－此例为主语从句，有误，感谢指出）
5、用if会引起歧义时，只用whether。如：
例12 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.
十、否定转移
1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I don't think I know you.我想我并不认识你。
I don' t believe he will come.我相信他不回来。
注意：若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you weren't ill. 我想你没有生病吧。
2) 将seem, appear 等后的从句的否定转移到前面。
It doesn't seem that they know where to go.
看来他们不知道往哪去。
It doesn't appear that we'll have a sunny day tomorrow.
看来我们明天不会碰上好天气。
3) 有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。
I don't remember having ever seen such a man.
我记得从未见过这样一个人。(not否定动名词短语having…)
It's not a place where anyone would expect to see strange characters on the street.
在这里，人们不会想到在街上会碰上陌生的人。
(anyone 作主语，从句中的谓语动词不能用否定形式。)
4) 有时状语或状语从句中否定可以转移到谓语动词前。
The ant is not gathering this for itself alone.(否定状语)蚂蚁不只是为自己采食。
He was not ready to believe something just because Aristotle said so. (否定because状语) 他并不因亚里斯多德说过如何如何，就轻信此事。
She had not been married many weeks when that man's younger brother saw her and was struck by her beauty.(否定状语many weeks)她结婚还不到几个星期，这个人的弟弟就看见她了，并对她的美貌着了迷。
名词性从句
1 名词 一般来说名词主要考查： 1．可数名词复数构成的规则及不规则变化。 2．可数名词和不可数名词的判断与用法——对比。 3．名词的所有格，包括’s所有格，…of…所有格和双重所有格的用法。 4．名词作定语和名词构成的习语及用法等。 5．名词的词义辨析。 2名词性从句有哪些引导词？并试着说明他们的用法。 热点一．语序与时态： 能力激活1： 想一想：名词性从句中的语序要注意什么问题？ 1. No one can be sure _____in a million years. A. what man will look like B. what will man look like C. man will look like what D. what look will man like 3. I don’t know when_____, but if he _____, I’ll let you know. A. he comes , will come B he will come , will come C he will come, comes D he comes, comes 小结1：不管主句是肯定句、否定句还是疑问句,名词性从句总是使用_____________. 观察与比较：I’m not sure if he will come ,but if he comes ,I’ll let you know . 小结2：主句是现在时态，宾语从句用_________________. 感悟疑点: He has come, but I didn’t know that he _____ until yesterday.

A. that she has got B. that has she got C. she has got D. has she got 思考：句中出现插入语时，语序该怎么办？ 疑点观察、总结与拓展： 4. What do you think we should do to solve the problem of air pollution in cities? 5. Where do you suppose he can be? 小结2：以上句子体现了何种句式结构？_____________________________ 小试牛刀： 6. Rose looks worried. What do you think ____________________(她该怎么办)? Exception :7．He went up to see ________ with her.
名词性从句用法详解
名词性从句用法详解 一、概说 名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。 二、名词性从句的一般引导词 1. 连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如： I hope (that) you enjoy your holiday. 希望你假期过得好。 That he likes you is very obvious. 很显然他喜欢你。 2. 连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。如： He asked whether [if] I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用if 代替whether) 3. 连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如： That’s why she wanted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。 4. 连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。如： The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。 三、名词性从句的重要引导词 1. what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是：一是表示“什么”，带有疑问意味；二是表示“…所…的”，相当于一个先行词后接一个关系代词。如： I don’t know what you want. 我不知道你想要什么。 I don’t know what you want is this. 我不知道你所想要的是这个。 2. what 引导名词性从句时可用作限定词，其后修饰名词。如： I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 注：what 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词，并且后接不可数 名词时，有时可有little修饰，两者的区别是：what+不可数名词=所有的都，what little+不可数名词=虽少但全部。如：

(2) 有时what 可用作限定词，其后修饰一个名词： I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 (3) What 后的名词可以是复数名词或不可数名词，但通常不能是单数可数名词： 误：I gave him what book I had.
名词性从句用法详解
高一语法专题：名词性从句 在句子中起名词作用的从句叫名词性从句。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，因此根据它在句中不同的语法功能，名词性 从句又可分为主语从句、宾语从句、表语从句、同位语从句。 引导名词性从句的词叫做连接词，包括：1. 连词（在名词性从句中只起连接作用，不 作成分） 2. 连接代词（在名词性从句中作主语、宾语 或表语） 3. 连接副词（在名词性从句中作状语） I 主语从句：是在主句中作主语的从句。它由连接词引导，通常位于谓语动词之前。 连接词：

高中英语名词性从句 which的用法
一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些 孩子使他更加生气了。 二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。 三、which 与what 的区别 用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。 从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里

名词性从句知识点总结
名词性从句 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：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。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意： 1、连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。 2、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。 That she was chosen made us very happy. We heard the news that our team had won. （二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesn’t matter so much whether you will come or not. 主要句型有： （1）It+be+形容词+that从句。 It is probable that he told her everything. 很可能他把一切都告诉她了。 （2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。 （3）It+be+过去分词+that从句。 It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 （4）It+seem, happen等不及物动词及短语+that从句。 It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 （5）It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。 3、that引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised. 4、当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need is more time and money. What we need are many more books. 5、if不能用在主语从句中，而是用whether Whether he left (or not) is unknown 6、引导主语从句的关联词有三类： (1)从属连词that。

英语语法名词性从句用法小结
英语语法名词性从句用法小结 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。 一. 名词性从句的连接词 引导名词性从句的连接词可分为四类： 1. that（无含义，不充当成分） 2. whether, if（有“是否”的含义，但不充当成分） 3. 连接代词：what, whatever, who, whoever, whom, whomever,whose, which,whichever. （在从句中做主语、宾语、表语和定语） 连接副词：when, whenever,where,wherever, how, however,why（在从句中做状语） 4. as if,as though,because（不充当成分，在名词性从句中只引导表语从句） 二. 四类名词性从句语法要点 1.主语从句 在整个句子中用作主语的从句叫主语从句。 What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。 Where the English evening will be held has not yet been announced.
英语晚会将在哪里举行，还没有宣布。 it 作形式主语：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。 It is clear that he is innocent in the accident. 很明显，他在这场事故中是无辜的。 2. 宾语从句 在整个句子中用作宾语的从句叫宾语从句。 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。 it 作形式宾语：在“主语+谓语+宾语+宾补”的句型中，如果宾语是从句的形式，则必须 用it 做形式宾语，把真正的宾语即宾语从句置于句末。 We found it impossible that the so much work will be finidhed in one day. 我们发现一天之内完成这项工作不可能。 3. 表语从句 在整个句子中用作表语的从句叫表语从句。 The fact is that we have lost the game. 事实是我们已经输了这场比赛。 That is why he didn’t come t o the meeting.
that引导名词性从句用法详解
that引导名词性从句用法详解 如何来掌握that引导的名词性从句呢？我认为应从以下几个方面掌握： 一．that 在名词性从句中，起连词的作用，在从句中不起语法功能，即不作任何成分，也不含有任何意义，引导名词性从句时，不可省略，故称：“三不”。 二．that引导名词性从句的特点 引导同位语从句： 当that引导同位语从句时，that从句前常有名词， 1) The idea that england stands for fish & chips ,speaker’corner, big ben and the tower of london is past 2) The fact that great britain is made up of three countries is still unknown to many. 3) The suggestion that students should learn something practical is worth considering 与 that 同位的名词常有下列名词： news ，fact, hope, idea, suggestion, promise, thought, doubt, belief, truth, request, proposal, demand etc. 2. that 引导表语从句 当that引导表语从句时，常用下列句式： it happens that…. it appears that…. it seems that…. it turns out that…. it proves that…. the reason is that… 1) It appears that he has gone mad。他好像是疯了。 2) It proves that his promise is wrong.。他的预言证明是错误的。 3) The reason is that he has not passed the exam. 原因是他考试没有及格。 4) It turns out that the situation is quite serious.形势结果是相当严重的。 3. that 引导主语从句 由连词引导的主语从句，在大多数情况下被放到句子的后面，用it 作形式主语来代替它的位置。常见的以it作形式主语的主语从句的句型有三种。 + be + 形容词+that从句 适用于这种句型的常见形容词有：necessary，clear，true，strange，important，wonderful，possible，likely，abvious，surprising etc。 1) It’s clear that they badly need help。很明显，他们急需援助。 2) It is likely that a hurricane will arrive soon. 很可能飓风马上就要来了。 3) It’s possible that we can carry out the project at last. 最终我们能完成这项工程是有可能的。 *** necessary，clear，true，strange,important,wonderful，possible, likely, obvious, surprising, ashtonishing,etc.谓语动词的形式一般为“should ＋动词原形” 4) It is necessary that you (should)master the computer. 你很有必要掌握电脑。 5) It is important that a student learn english well. 学生学好英语很重要。 6) It is strange that he should have killed himself .真奇怪，他竟然自杀了 b. it +be +名词词组+ that从句

名词性从句基本用法及考点归纳
名词性从句基本用法及考点归纳 孝昌一中郭小青对名词性从句的考查是湖北卷完成句子试题很重要的一个部分，查看近几年的湖北高考完成句子都将名词性从句作为各种从句的必考点。如： 2007年湖北省高考题1:I haven’t the slightest idea(他正在说什么).(talk) 此题考查宾语从句、现在进行时和动词短语，答案是（of）what he’s talking about 2007年湖北省高考题2：The fact __（他失败了数次）makes him very upset (he, fail)此题考查同位语从句和现在完成时，答案是that he has failed (for) several times 2007年湖北省高考题3：(他是否出过国)doesn’t make much difference.(he, abroad) 此题考查主语从句和现在完成时，答案是Whether he has been abroad or not 2008年湖北省高考With the rapid development of science and technology，I can’t imagine_____________ (我的家乡会是什么样子) in ten years. ( what) 此题考宾语从句，答案是what my hometown will be/look like 注意用将来时且是陈述语序2010年湖北高考The news______________ (房价将要下跌) has caused many people to sell their houses at lower prices. 此题考同位语从句，用“that” 引导，“房价”译成“housing price”，答案是“that the housing price will fall”。 从中可看出，虽然对名词性从句的考查比重在下降，2007年有3道题涉及名词性从句的考查，而2008年，2009年只有一题，，但2010年还是再次考查了名词行从句中的同位语从句。可见，高中对名词性从句的把握还是很重要的。其命题规律：一般不给出连接词，增加题目难度；有时还会在期中穿插其他语法，比如说时态，语态，动词搭配等来增加试题难度。 当然，不管怎么考查，作为学生们首先得弄清楚名词性从句的其本用法。 名词性从句基本用法： 概念:在复合句中起名词作用的从句叫名词性从句(Noun Clauses)。名词性从句的功能相当于名词或名词词组, 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。 名词性从句在功能上相当于名词： 如：主语：His job is important. What he does is important. 表语：This is his job.This is what he does every day. 宾语：I don’t like his job. I don’t like what he does every day 同位语：I don’t know about the man, Mr. White. I don’t know about the fact that he is a teacher. 一．主语从句：充当句子主语的从句 eg. That he will succeed is certain.
What--和that-在名词性从句中的用法区别
What 和that 在名词性从句中的用法区别 What 和that 都可以引导名词性从句。 一．在引导名词性从句时，从属连词that一般要注意三个不（three nos）： 1．不省略（no ellipsis） 当从属连词that引导主语从句、表语从句和同位语从句时，that不省略。 Eg. 1) That he was able to come made us happy.(That 引导主语从句不可省略) 2)The truth is that I didn’t go there. (that引导表语从句不可省略) 3)The news that our team has won is true. (that引导同位语从句不可省略) 但在非正式文体中that 引导宾语从句时可以省略，除下列两种情况外： that在宾语从句中不能省略的情况. (1). 在主+谓+it(形式宾语)+宾补+that，从句(真正宾语) 的句型中不省略. Eg: 4) He made it quite clear that he preferred to study English.（that不可以省略） 他很明确地说他宁愿学习英语。 (2). 由连词and连接的两个由that引导的宾语从句中, 则第二个宾语从句前的that不省略。Eg: 5) He told me that he would come and that he would come on time.（第一个That可以省略，但第二个that不可以省略。)他告诉我他将来而且他将准时来。 2．不作成分（no component） that 在名词性从句中不作任何句子成分。 Eg. 6)Sydney kept his promise that he would always do anything he could for Lucie to make sure of her happiness.（that在句中引导同位语从句，但在句中不作任何成分） 7))That you don’t like him is none of my business. (that在句中引导主语从句，但在句中不作任 何成分，也不省略） 3．没词义（no meaning） that 在名词性从句中没有汉语意思。 Eg. 8)That she is a rich woman is known to us. (that在句中引导主语从句，但在句中没有汉语意义) 她是一个很有钱的女子，这一点我们都知道。 9）The thought that he might fail in the exam worried him. (that在句中引导同位语从句，但在句中没有汉语意义） 他也许会考试失败，这一想法使他很担心。 二．在引导名词性从句时，What一般要注意一个不（one no）,一个有（meaning）,一个作（component）： 1．不省略 what 引导名词性从句时，what 在句中不省略。这一用法与that 用法不尽相同。 eg. 10) What I had for breakfast today was rice with egg.(what 在句中引导主语从句，what 不省略) 11)----I think it’s going to be a big problem. ----Yes , it could be . ----I wonder what we can do about. (what在句中引导宾语从句，但在句中不省略） 2．有词义 what 引导名词性从句时，有词义。一般是“----的东西/事情/话等”这一用法与that 用法不一样eg. 1) This is what she wanted to show us. (what在句中引导表语从句，在句中有词义，意思是“----的东西、事情）这是她想让我们看的东西。 12）What the teacher said had a good effect on the children. (what在句中引导主语从句，在句中有词义，意思是“----的东西、事情）老师所说的话对孩子们有很好的作用。 3．作成分
