在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，名词性从句我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。
主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what,
which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how,
why, however, whenever, wherever等。

一、考点聚焦
1、名词性从句中连接词的运用
名词性从句中的连接词有连词that / whether / as if，连接代词what / who/ which / whose /
whatever / whoever / whomever / whichever，连接副词where / when / why / how / wherever
/ whenever。
（1）that的用法。
①主语从句、表语从句、同位语从句中用that但不能省略。如：
That they are good at English is known to us all.
The problem is that we don't have enough money.
She expressed the hope that they would come to China one day.
②宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：（A）当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时，that不可省略；（B）当that
从句与另一名词性从句并列作宾语时，that不能省；（C）当that作介词宾语时，that不可省掉。如：
He judged that, because he was a child, he did not understand wine
Everyone knew what happened and that she was worried.
The reason lies in that she works harder than the others do.
③that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。
实用文档
(A)It is clear/certain/likely/true/surprising that…（B）It is a
pity/shame/good idea/no
wonder that ...（C）It is said/reported/
believed/known/thought/suggested that …（D）It
seems/happens that。如：
It happened that I went out last night.
It is said that China will win in the World Cup.
④that和what的区别。
that 引导名词性从句时，在主从句中不以当任何句子成分，也没有任何含义；而what引导名词性从句时，在主从句中都要充当一定的句子成分，what可以分解成定语从句中的先行词+ 关系代词即常说的先行词+ that。如：
It's shame that he has made such a mistake. Do what he says.
⑤同位语从句与定语从句中that的区别。
同位语从句中的连词that只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代词that在句中做宾语或主语，宾语与先行词有修饰关系。如果句子是同位语从句，就应用连词that而不能用which.同位语从句一般放在表
具体含义的名词后解释名词的含义或内容，如以下名词：news、fact、suggestion、truth、plan、belief、doubt、possibility、idea等，而定语从句只是对先行词的限定和修饰。如：
They expressed the hope that they would come to visit China again.(同位语从句)
The hope she expressed is that they would come to visit China again.（定语从句）
（2）whether和if的用法。
①whether和if在宾语从句中可以互换，但是作介词宾语时连接词一般用whether。如：
It all depends on whether they will come back.
②后面直接跟or not 时用whether。如：
I didn't know whether or not he had arrived in Wuhan.
③主语从句表语从句中只能用whether。如：
Whether the meeting will be put off has not been decided yet.

The question is whether they have so much money.
④whether可以引导同位语从句，用以说明前面的名词的内容，if不能。如：We ought to discuss carefully the question whether we can do
it or not.
⑤whether常与or连用表示一种选择，if不能这样用；whether也可与动词不
名词性从句精讲 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。That he will come h ere surprises me. I know that he will come here. The news is that he will come here.The new that he will come here surprises me. 一、名词性从句的相同点：1.结构 2.连接词 引导名词性从句的连接词可分为三类： 从属连接：that, whether, if（不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 二、四大名词性从句的剖析 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： That he suddenly fell ill last week made us surprised. 上星期他突然生病了让我们很惊讶。 Whether he will be able to come remains a question.他是否能够来仍然是一个问题。What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。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。 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 +形容词+主语从句It is very interesting that he likes such kind of books. （2）It + be +名词+主语从句It is a pity that he missed the lecture. （3）It + be +动词的过去分词+ that从句It is said that they have won the game. （4）It +不及物动词+ that从句It seems that something is wrong with the computer. 另注意在主语从句中用来表示必须、理应如此、建议、要求等语气时，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… 2.宾语从句 名词性从句用作宾语叫宾语从句，在句中可以作谓语动词或介词的宾语。引导宾语从句的连接词与

名词性从句解题方法 <方法>——先大类后口诀法 第一步：先分析出大的类别——定从/名从/状从 即分析所缺部分在主句中的成分从而确定从句大的类别第二步：口诀逐一解决： (I)名词性从句。——口诀——先成分后含义 (II)定语从句。——口诀——先成分后先行词 (III)状语从句。——口诀：翻译即可 例如：名词性从句的口诀执行方法是： 分析引导词在从句中的成分 A 做名词性成分——what/which/who/as(+W-ever型) B 做非名词性成分 a 不做成分：that/if/whether(whether霸王原则) b 做状语成分：when/where/why/how 一旦分出AB两类，剩余的靠含义直接翻译即可解决。
例如A computer can only do _________ you have instructed it to do. (01年31题) A. how B. after C. what D. when 解：第一步：先分析出大的类别 A computer can only do中的do是及物动词，后面缺少do的对象，所以考察名词性从句问题 第二步：口诀——先成分后含义 从句you have instructed it to do中的do是及物动词，后面缺少do的对象，所以前面的空在后面的从句内充当名词性成分，所以可以选择的引导词就可以排除AD(因为这两个引导词在从句中是充当状语的)，而选项B是名词性从句中不存在的引导词，所以B也不对，最后就剩下一个正确选项C 如此这样一步一步下来，逐一进行排除和选择，最终总是可以直接定位到正确的答案。而这个过程应该是完全被熟化在脑中的一个过程，按部就班的操作直至正确答案自然而然的浮出水面。 其他类别的题目也应该仿照此类，依次完成。 2、建立良好的做题习惯，沉稳面对每一个考验。
四种名词性从句(宾语从句、主语从句、同位语从句、表语从句)讲解与练习 ◆学习宾语从句 学习宾语从句的连词、语序、时态和各种变化及特殊用法(直接引证变间接引语也在 宾语从句的基础上还要进行人称、状语、少数动词和句型的变化)是为学习其它三种名词性从句(主从、表从、同位从)做铺垫，连词、语序、时态基本相同，只是后三种考点相对宾.语从句少的多，主要是对连词的应用进行考查。所以学好宾语从句是必要的。 宾语从句三注意三特殊 一注意:注意引导词(连词) 由陈述句转化而来的宾语从句，引导词为that，that 在口语或非正式文体中可省略;由 一般疑问句转化而来的宾语从句，引导词为if或whether;由特殊疑问句转化而来的宾语从句，引导词为句子本身的特殊疑问词，即what, when，where 等。 Eg：Tom says(that)he will fly to Beijing tomorrow. 汤姆说他明天将要坐飞机去北京 二注意:注意从句语序. 宾语从句的语序应该为陈述句语序即“主语+谓语+宾语+其他”。也就是说将疑问句转化成宾语从句时，一定要将疑问句语序转变成陈述句语序。 Can you tell me what he is doing能告诉我他正在做什么吗? <特别提醒>当疑问句在宾语从句中做主语时，语序不变。 Eg：Do you know what makes him so angry? 你知道什么事使他如此生气吗？ <特别提醒>如果宾语从句表示的是客观真理或是科学事实，其谓语动词仍用一般现在.时态。 Eg：Our teacher told us that the sun is much bigger than the moon. 老师告诉我们说太阳比月球大得多。 ◆主语从句(与宾词从句连词、语序、时态相同。只是不能用if, that 不可省;) (一)、主语从句是一个句子，在句子中作主语成分。 (二)，主语从句的特点 1.与宾语从句使用同样的连接词，只是if不能用; 1)、陈述句用that。 2)、一般疑问句用whether。 3)、特殊疑问句用特殊疑问词what, which, who,when, where, why, how等词引导。 2.以it为形式主语出现 Eg：1.It's true that the earth is round. That the earth is round is true. 2.表是否的意思时，不能用if代替whether. It hasn't been decided whether he'll come or not. Whether he'll come or not hasn't been decided. 3.从句语序为主谓宾正常语序。 Why didn't he come? Why he didn't come is not known. （三）特殊疑问词变化 Whoever=no matter who=any one who Whomever=no matter who=any one who
名词性从句精讲精析 ——主语从句、宾语从句、表语从句、同位语从句 名词性从句是由if, whether, that 和各种疑问词充当连接词所引导的从句，其功能同名词一样。 一．主语从句 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 1. 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. 2. 用it 作形式主语的结构 (1) It is ＋名词＋从句 It is a fact that … 事实是… It is an honor that …非常荣幸 It is common knowledge that …是常识 (2) it is ＋形容词＋从句 It is natural that… 很自然… It is strange that… 奇怪的是… (3) it is ＋不及物动词＋从句 It seems that… 似乎… It happened that… 碰巧… (4) it ＋过去分词＋从句 It is reported that… 据报道… It has been proved that… 已证实… 3. 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。(it is uncertain if he will leave for Beijing tomorrow. )

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，名词性从句可分为主语从句、表语从句、宾语从句和同位从句。 引导词：主语从句就是在复合句中用作主语的从句，引导主语从句的引导词主要有三类：一是that；二是whether；三是那些可以用作疑问词的词语，如what, who, which, when, where, how, why等 （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：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）。 一、主语从句 与宾词从句连词、语序、时态相同。只是不能用if, that 不可省； （一）、主语从句是一个句子，在句子中作主语成分。 （二），主语从句的特点 1.与宾语从句使用同样的连接词，只是if 不能用； 1）、陈述句用that。 2）、一般疑问句用whether。 3）、特殊疑问句用特殊疑问词what, which, who,when, where, why, how 等词引导。 2.经常隐身（以it为形式主语出现）。 例句： 1.It's true that the earth is round. That the earth is round is true. 2. 表是否的意思时，不能用if代替whether. It hasn't been decided whether he'll come or not. Whether he'll come or not hasn't been decided. 3. 从句语序为主谓宾正常语序。 Why didn't he come? Why he didn't come is not known.

(表语从句) 我的希望是她能很快康复。 2) Everybody hopes that she will soon be well again.（宾语从句） 大家都希望她能很快康复。 3) That she will soon be well again is our hope.（主语从句） 她能很快康复是我们的希望。 b. whether, if（均表示“是否”表明从句内容的不确定性，不作成分） 1) Whether he is coming or not doesn’t matter too much.(主语从句，不能用if) 2) I went in and asked if/whether they had a cheap suit. 3) I wonder whether/if he will come in such bad weather. c. 连接代词：what, whatever, which, whichever, (在从句中作主语，宾语，表语，指物) 1) ____he need is more time. 显然，主语从句：he是主语，谓语动词need缺宾语，因此应填what. 2) Tell us ___you saw and heard during your visit to that university. 3) This is not ___I want. 4) ____some people are against is ___other people are for. 5) The question is which team will win. 6) I have two apples, I don’t know which you want. 归纳：what一般用于不知道内容或范围的句子；which“哪一个……”一般用于给出内容或范围的句子。可作主语，宾语，表语，还可作定语。 d. who, whoever, whom, whomever, whose（在从句中作主语，宾语，表语，定语，指人） 1) Who will give us a lecture is unknown. 2) The question is who will come here. e. 连接副词：when, where, how, why, whenever, however, wherever (在从句中作状语) 1) I have no idea how he learned about it. 2) Where she has gone is not known yet. 3) When he will start is not known yet. 4) This is why he is late. 注意：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。
名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what, which, whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。 That you don’t like him is none of my business.你不喜欢她不管我的事。 What he said is true. 他说的是真的。 Do you remember how he arrived almost at the end of the party?你记得他几乎是在宴会快结束时才到的吗？ This party's really where it's at, man! 啊，这个晚会真棒！Tell us how you fulfilled the heavy task ahead of schedule.告诉我们,你们是怎样提前完成这一艰巨任务的。 We have reason to believe that the fighting on the border may develop into a full-blown war.

(主语从句) The trouble is that she has lost his address.（表语从句） They have no idea at all where he has gone.（同位语从句） Do you remember how he came?（宾语从句） 二、主语从句(subject clauses) 1、概述 在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、关系代词、连接副词等。引导主语从句的关联词有从属连词that 、whether ，关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever ；关系副词：when, where, how, why, however, whenever, wherever 等。 That you don’t like him is none of my business. What he said is true. Whether the football game will be played depends on the weather. 2、从属连词that ，whether 引导的主语从句。 从属连词that ，whether 在主语从句中的作用只是引导主语从句，它们在从句中不担任成分，不能省略。 Whether she will come or not is still a question. That they will go is certain. Whether she's coming or not doesn't matter too much. 3、it 作形式主语引导主语从句。 如果主语从句太长，为避免句子结构头重脚轻，我们可用it 作形式主语，而把主语从句放在主句谓语部分之后。That 引导的主语从句可用it 代替，that 不可省略。 用作it 作形式主语的结构： （1）It is/was +形容词+that 从句 It ’s natural that … 很自然…… It ’s obvious that … 显而易见…… （2）It is/was +名词+that 从句 It ’s a pity that … 遗憾的是…… It ’s a fact that …事实是…… 鹰击长空—基础不丢
