名词性从句
在句子中起名词作用的句子叫名词从句（Noun Clauses ）。名词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、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：
连词：that （无任何词意）
whether, if 均表示“是否”表明从句内容的不确定性）
as if ,as though （均表示“好像”，“似乎”）
以上在从句中均不充当任何成分
连接代词：what, whatever, who, whoever, whom,
whose, which. whichever, whomever
连接副词：when, where, how, why
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.
比较：
whether 与if 均为"是否"的意思。但在下列情况下，whether 不能被if 取 代：
1. whether 引导主语从句并在句首
2. 引导表语从句
3. whether 从句作介词宾语
4. 从句后有 "or not"
Whether he will come is not clear.
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.
二 . 主语从句
1. 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.
Who will win the match is still unknown. 知。
It is known to us how he became a writer.
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。
他要跟我们说什么,还不清楚 谁能赢得这场比赛还不得而
我们都知道他是如何成为一
2. 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
（2）It + be + 形容词+ that 从句
（3）It + be + 动词的过去分词+ that 从句
It is believed that 25 years after construction, the building was dismantled and moved timber by timber to the South Bank of the Thames, where a reconstruction of the theatre now stands.
据信经过25 年的建设后, 该建筑物将被拆处. 并且该建筑物的一砖一石将被移到泰唔士河的南岸. 重建的戏剧院现在正座落于此。
It is thought the cost of this lost labour is around ￡ 1 billio n （10 billi on yua n）
to businesses and the economy.
大家一直认为这次对贸易和经济失去劳动力的损失的费用应该在10 亿英镑（人民币100 亿元）
It is not known how many of the 59 million words Mr Shea has remembered but he has certainly made history with his eccentric hobby.
在590 万的词汇中到底记住了多少不得为知, 但是她却以这样的怪癖创造了历史。
4）It + 不及物动词+ that 从句
3. 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 n ecessary (importa nt, n atural, stra nge, etc.) that …
It is a pity (a shame, no won der, etc.) that ?…
It is suggested (requested, proposed, desired, etc.) th at …
4. 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。被强调部分指人是也可用who/whom例如：
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.
5. 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。
(1) What you said yesterday is right. (2) That she is still alive
is a consolation.
名词性从句--- 宾语从句; 表语从句
(2009-03-18 22:15:32)
转载三、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. 作动词的宾语:
1) . 由that 引导的宾语从句( that 通常可以省略, 例如：

诉我他明天要去上海。

Well, today I have to say 'spring is in the air' - which means
there is a feeling around us that spring is coming 好吧，今天我要说春意盎然，那将意为我们有一种感觉那就是春天来了。
2) . 由what, whether (if) 引导的宾语从句，例如：
She did not know what had happened.
她不知道发生什么
事了。
I wonder whether you can change this note for me.
我想知道是否你能为我换开这张钞票。

宾语从句的引导词
宾语从句的引导词 一、宾语从句：置于动词、介词等词性后面，在句子中起宾语作用的从句叫做宾语从句。宾语从句分为三类：动词的宾语从句，介词的宾语从句和形容词的宾语从句。宾语从句过”三关“：时态，语序，连词。宾语从句的语序必须是陈述语序, 谓语动词、介词、动词不定式，v.-ing形式后面都能带宾语从句，有些形容词(afraid, sure, glad等)之后也可以带宾语从句。 二、宾语从句中引导词的用法 在复合句中作主句的宾语，引导词有： 连词：that (that 常可省略),whether, if 代词：who, whose, what ,which 副词：when ,where, how, why 等。 (-)that引导的宾语从句(在非正式场合that可以省略) 可跟that从句做宾语的动词有： say, think, in sist, wish, hope, dema nd, imagi ne, won der, know, suppose, see, believe, agree, admit, deny, expect, explai n, order, comma nd, feel, dream, suggest, hear, mean, notice, prefer; request, require, propose, declare, report 等。彳列句：The boy believes that he will travel through space to other planets. (注意事项:当主句谓语动词是think, believe, suppose, expect等词，而宾语从句的意思是否定时，常把否定转移至主句表示。) 例句：I don' t think it is right for him to treat you like that? 在以下情况中that不能省略 1、当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面 的that不可省。 例句：He said (that) you were too young to understand the matter and that he was asked not to tell you. 2、当主句的谓语动词与that宾语从句之间有插入语时，that-般不可省。 仮!1 句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap?

It’s the first position that I have written in English. （2）先行词前有 any, all, few, little, the only, the right, the very, the last 等修饰时。 eg. You are the last people that get the chance to attend the party. （3）先行词是不定代词 all, some, something, anything, nothing 等时。 eg.

宾语从句引导词英语语法大全
宾语从句引导词 如果从句是陈述句，引导词用that（that在口语或非正式文体中常省略）；如果从句是一般疑问句，引导词用if/whether；如果从句是特殊疑问句，引导词用由疑问词转换而来的疑问代词/副词。 一) 以that 引导的宾语从句，主要用来引导陈述句形式的宾语从句，that可以省略。 I know (that) he is a Canadian athlete. Do you think (that) the children need to write a song? Maria says (that) she doesn’t like the uniforms. She told me (that) she would like to go with us. 二) 以whether 或if 引导的宾语从句，主要用来引导一般疑问句意思或选择疑问句意思的宾语从句。 whether和if都可以引导宾语从句，表示“是否”，在口语或间接引语中两者可以互换使用。如： I wonder if / whether I can get some advice from you. Ask him whether / if he can come. 但在有些情况下，只能用whether，不能用if： 1. whether引导的从句常可以与连词or或or not直接连用，而if一般不能。如： 正：Let me know whether you can come or not. 误：Let me know if you can come or not. 2. 当宾语从句提到句首时，只能用whether引导，而不能用if。如： 正：Whether it is true or not, I can’t t ell. 误：If it is true or not, I can’t tell. 3. whether可以引导带to的不定式，if则不能。如： 正：I don’t know whether to accept or refuse. 误：I don’t know if to accept or refuse. 4. whether及其引导的成分可放于介词之后，作介词的宾语，但if不能。如： 正：I worry about whether I hurt her feelings. 误：I worry about if I hurt her feelings. 5. whether可以引导从句，作主语、表语或同位语，而if不能。如： 正：It was uncertain whether he would come. 误：It was uncertain if he would come. 6.若用if会引起歧义时，则用whether。 Please let me know if you like the book．可理解为： a．Please let me know whether you like the book. b．If you like the book，please let me know. 三) 疑问词引导的宾语从句 疑问代词：what、whom、who、whose、which 疑问副词：when、where、why、how 例句：1、The book will show you what you must do .

英语名词性从句的连接词选用
名词性从句的连接词选用 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同位语从句的词通有连词that，whether，连接副词how,when,where等。（注：if 不能引导同位语从句。）。在各种考试中，其最主要的考查内容为连接词的选用。名词性从句的连接词可细分为以下四种：（1）以that来引导从句；（2）以whether/if引导从句；（3）以特殊疑问词引导从句；（4）以关系代词/副词引导从句。 一、以that引导从句 当从句的意思已完整时，名词性从句用that引导，that在从句中不作任何句子成分，仅起连接作用。如： It is certain that he will do well in his new job. （主语从句） Do you know that he has been admitted to Beijing University? （宾语从句） My decision is that we are to start at 6 tomorrow morning. （表语从句） The news that our team had won the game excited everybody. （同位语从句） 当用that引导从句时，需注意以下情况： 1．在主语从句中，that一般不可省略，尤其是当主语从句位于句首时，它绝对不可省略。如： That our team had won the game was good news to us. 2．在宾语从句中，that可省略。但当句中有两个并列的宾语从句时，引导第二个宾语从句的that不可省略。如： Everybody knows (that) the earth goes round the sun. Everyone knew what happened and that she was worried. 3．当句子是以it作形式宾语时，引导宾语从句的that不可省略。如： He has made it clear that he will not give in. 4．that一般不能引导介词的宾语从句，偶尔可在except, but, besides和in（在于…；在…方面）的后面引导宾语从句，that不可省略。如： Your homework is quite good except that you have made two small mistakes. The reason lies in that she works harder than the others do. He differed from other people in that he always looked farther ahead in his work. 在其它介词后面需要用that引导宾语从句时，必须用it作形式宾语。如： You may depend on it that I shall always help you. 5．在表语从句和同位语从句中，that不可省略。如： My advice is that you must give up smoking right now. The fact that he is a thief shocked all of us. 二、以whether/if引导从句 引导名词性从句的whether/if意为“是否”。在使用时，要注意两者存在以下区别。 1．在主语从句中，whether既可引导位于句首的主语从句，也可引导用it作形式主语的主语从句，而if只能引导以it作形式主语的主语从句。如： Whether the work can be completed on time is doubtful. It is doubtful whether/if the work can be completed on time. 2．在宾语从句中，当其后紧跟or not时，只能用whether，不能用if。如： I don’t care whether/if he comes or not. I don’t care whether or not he comes. 3．在介词后面的宾语从句中，只能用whether，不能用if。如： It all depends on whether they will come back.

名词性从句引导词的判断选择思路分析
名词性从句引导词的选择思路分析 一、名词性从句的一般做题步骤：1.根据句意，分析句子结构，判断名词性从句的类别；2.根据句意，分析从句部分是否缺成分，（如果从句部分不缺成分，从that/if/whether中选择；如果从句缺少主语，宾语，个别缺表语，从连接代词what/whatever/who/whoever/which等中选择；如果从句缺少状语，从连接副词how/when/where/why等中选择。） 3.分析选项中各引导词的区别。 二、名词性从句中的疑难、易混点： 与who: 两者都可以做主语，宾语，但who是疑问代词，在从句中仍有疑问含义，翻译成“谁”，所引导的从句表示一件事；而whoever无疑问含义，翻译成“…的人”，相当于“anyone who..”，所引导的从句表示“…的人”。类似地，what有疑问含义，“什么”；whatever无疑问含义，“无论什么”。 与no matter what：区别在于引导的从句有差别：whatever主要用来引导名词性从句（也可以引导让步状语从句）；而后者只可以引导让步状语从句（一般用逗号与主句隔开），不能用在名词性从句中。所以一定要分析从句类型。所有的疑问词+ever与no matter + 疑问词的区别同上。 与what:主要区别在含义上，which“哪一个”，句中一般有供选择的范围；what“什么”，“…的”，一般无选择范围。eg, there are so many books here, so I don’t know which I should choose. 与that区别：在所有名词性从句中，that不做成分，只起引导作用；而what在名词性从句中，起引导词作用，还有做主语，或者宾语等成分。在定语从句中，that可做主语，宾语；what不能用在定语从句中。
