名词性从句（宾语从句、表语从句、主语从句）六大基本句型
1主系表句型----- be （连系动词do）
2、主谓宾----- do（vt）
3、主谓----- do(vi)----(不及物动词)
4、主谓宾补----do(vt)
5、主谓宾宾---do(vt) 记双宾语的动词一定要记。
6、There be (不及物动词do)--------be (不及物动词)
宾语从句定义：在主谓宾句型的宾语的位置上把做为名词的宾语扩展成一个be句型或者do句型。可以用下列公式进行表示：主语+谓语+从句。
宾语从句的连词① that , ②whether(or not)或if; ③which(whichever),
who(whoever)，whom(whomever) ，whose(whosever)，what(whatever); ④
when(whenever)，where(wherever)，why，how(however); ⑤ how many, how much, how long, how often，how soon
宾语从句的形式：
1、主谓宾句型的宾语从句: 作为名词的宾语扩展成一个be句型或者do句型。
He knows the news
He knows that the teacher is in classroom
2、主谓宾宾---do(vt) 句型的宾语从句，把直接宾语变为一个be或do句型。
He tells me the news
He tells the news to me
He tells me that she is a teacher
He tells that she is a teacher to me
3、主谓宾补句型的宾语从句需要it来做形式宾语
I find Chinese important
主谓宾补
I find that we make a quick decision about this matter important
主谓宾语从句补
I find it important that we make a quick decision about this matter
主谓形式宾语补宾语从句
I think it necessary that we take plenty of hot water every day .
我认为每天多喝开水是有必要的.
I feel it a pity that I haven’t been to the get-together.
我没去聚会,感觉非常遗憾.
I have made it a rule that I keep diaries.
我每天写日记成了习惯.
4、宾语从句的省略形式：
某些形容词后面可以带宾语从句，其形式为sb+be+形容词+that宾语从句：这一类形容词通常是表示人物的心理，情感等状态的形容词如：
sure, certain, glad, please, happy, sorry, afraid, satisfied, surprised
a. I am glad (that) you helped me.
b、I am sure (that) you can pass the exam.
1、I am glad of your help.
2、I am sure about your exam.
分析：上面句子中介词后面所跟成分都做介词宾语。我们完全可以将他们换成that+陈述句:
3、I am glad of that you helped me.
4、I am sure about that you can pass the exam.
从语法上讲，以上的结构都是正确的。但是，由于这样表达过于啰嗦，所以我们可以将其简化，省去介词，由于它们是宾语从句，所以连同that也可以省掉，因此，这是一种省略形式的宾语从句。
表语从句
同样的道理，如果在主系表句型表语的位置上把表语变成一个be句型或者do句型，则称为表语从句。
①The question is difficult -------_the question is how we make money .
主语系表主语系表语从句
②The question is difficult -------- the question is that she is a thief
主语系表语从句
③The question is difficult -----the question is that there is a thief in the room
主语系表语从句
④事实是因为每个人都要生活------ the fact is because everyone must live
小结：表语从句的引导词与宾语从句一样，规律与宾语从句一样，只不过称呼不同而已，因此掌握宾语从句以后，表语从句无需特别学习。但要注意以下几点：
1、不可以用if，而用whether 连接表语从句(as if 例外）。
False: The question is if the enemy is marching towards us.（错误）
Right: The question is whether the enemy is marching towards us.（正确）
2、that在表语从句中不可以省掉。
the question is that she is a thief
3、注意比较That is because...”句型与that is why….句型
“That is because...”与“That is why...”之间的不同在于“That is because...”指原因或理由，“That is why...”则指由于各种原因所造成的后果。例如：1：He did not see the film last night.
That is because he had to help his little sister with her homework.
2、He had seen the film before.
That is why he did not see it last night.
(第一句话说明原因，第二句话说明结果)
4、当主语是reason, fact，idea等抽象名词时，表语从句的连接词应该用that.
①The reason is that he didn’t go to school
②The traditional view is ____ we sleep because our brain is “programmed”tomake us do so.
A when B. why C. whether D. that
③You are saying that everyone should be equal, and this is ____ I disagree.
A. why
B. where
C. what
D. how
主语从句
如果将主谓宾或主系表的主语扩展成为一个句子，称为主语从句：
①The question is difficult ----that she makes money is difficult
主语系表主语从句系表
----- it is difficult that she makes mon ey
形式主语系表真正的主语
It= that she makes money 主语从句的结构：it is….that…..
②the cat is a fact ----- that there is a cat in the room is a fact
主语从句
it is a fact that there is a cat in the room
形式主语系表真正主语
③he knows the news---- that he knows the news surprises me
It surprises me that he knows the news
小结：主语从句的引导词与宾语从句一样，规律与宾语从句一样，只不过称呼不同而已，因此掌握宾语从句以后，主语从句无需特别学习。但需要注意两点：1,主语从句有形式主语it
2, 引导词if不能引导主语从句，只能用whether….(or not)
If 不能引导主语从句———他明天是否上学还不知道 if he will go to school is unclear (错误) it is unclear if he will go to school（错误）
Whether he will go to school is unclear It is unclear whether he will go to
school (正确)
3、以下几点需要注意：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 was the football team and It had(who) helped the old man
4、(1) 主系表的主语从句形式it +系+表+从句
It is a fact that …事实是…
It is natural that…很自然…
(2)主谓宾的主语从句形式：it+谓语（及物动词）+宾语+从句
（3）主谓的主语从句形式：it +谓语（不及物动词）＋从句
It seems that…似乎…
It happened that…碰巧…
(4)主谓宾宾的主语从句形式：it +谓语+宾语+宾语+从句
(5)主谓宾补的主语从句形式：it +谓语+宾语+补语+从句

我国古代的读书人,从上学之日起,就日诵不辍,一般在几年内就能识记几千个汉字,熟记几百篇文章,写出的诗文也是字斟句酌,琅琅上口,成为满腹经纶的文人。为什么在现代化教学的今天,我们念了十几年书的高中毕业生甚至大学生,竟提起作文就头疼,写不出像样的文章呢?吕叔湘先生早在1978年就尖锐地提出:“中小学语文教学效果差,中学语文毕业生语文水平低,……十几年上课总时数是9160课时,语文是2749课时,恰好是30%,十年的时间,二千七百多课时,用来学本国语文,却是大多数不过关,岂非咄咄怪事!”寻根究底,其主要原因就是腹中无物。特别是写议论文,初中水平以上的学生都知道议论文的“三要素”是论点、论据、论证,也通晓议论文的基本结构:提出问题――分析问题――解决问题,但真正动起笔来就犯难了。知道“是这样”,就是讲不出“为什么”。根本原因还是无“米”下“锅”。于是便翻开作文集锦之类的书大段抄起来,抄人家的名言警句,抄人家的事例,不参考作文书就很难写出像样的文章。所以,词汇贫乏、内容空洞、千篇一律便成了中学生作文的通病。要解决这个问题,不能单在布局谋篇等写作技方面下功夫,必须认识到“死记硬背”的重要性,让学生积累足够的“米”。A. when B. how.
C. what D .where
37. ---Do you have anything in mind ______you'd like for supper ?
---Well, ______will do for me.
A. which, everything

Dressed in red, she looks as if she were ten years younger. 13. Has it been decided when we’ll have the final examination? 【总结】 主语从句和表语从句都属于名词性从句。主语从句在复合句中作主语，表语从句在复合句中作表语。在具体的应用中要掌握以下几点： ● 引导词(详见P138-139, B7) 注意易错引导词： (1) 引导主语从句位于句首时只能用whether (如例句3)，句中可用if (如例句2)，引导表语从句只能用whether (如例句6)； (2) 主句的主语是reason时，表语从句要用that，不能用because引导(如例句8)； (3) 引导表语从句时，why强调结果(如例句9)，because强调原因(如例句10)； (4) that只起连接作用，不在从句中作成分，无词义。引导主语从句时不能省略，引导表语从句时可以省略。 ● it作形式主语 有时为避免句子头重脚轻，常用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。主句的谓语动词一般用单数形式： (1) 常用句型：It+be+名词词组/形容词/过去分词+ that从句(如例句4-5)； (2) 在由连词wh-引导的主语从句中，从句可放在句首，也可用it作形式主语而把从句放在句末(如例句2、 13)。 ● 语序：主语从句和表语从句必须用陈述语序。 ● 主谓一致 主语从句作主语时谓语动词用单数形式。what引导主语从句，主句的谓语动词多用单数形式，但若表语是复数时，谓语动词用复数形式(如例句1)。 ● 语气
Ⅰ.用适当的连接词填空 1．The trouble is that I can’t find my way. 2．We are discussing what we shall do to help the poor. 3．It depends on whether you can do the work well. 4．I wonder how you are getting on with your studies. 5．He got caught in the heavy traffic.That was why he was late. 6．Energy is what makes things work. 7．We didn’t set out; it was because we wanted to wait until our mother came back. 8．We consider it necessary that he should improve his pronunciation. Ⅱ.单项填空 1．—Can you join us in the party this evening? —Well, that depends on ________ I can finish my report before then. A．whether B．if C．that D．when 解析：选A。句意：“你今天晚上能参加我们的聚会吗？”“嗯，那得看到时候我的报 告能不能完成。”连词whether表示“是否”，引导宾语从句。if表示“是否”，不引导介词的宾语从句；that没有意义；when“当……时”。 2．I don’t think ________ possible ________ one can master a foreign language without much memory work. A．it; whether B．it; that C．which; whether D．this; that 解析：选B。it在句中作形式宾语；possible作宾补；真正的宾语是that引导的宾语从句。 3．He said________he had eaten nothing for a long time and________he was very hungry. A．that; 不填B．不填；that C．不填；不填D．what; what 解析：选B。考查宾语从句中that的省略问题。said后接了两个that引导的宾语从句，其中第一个从句中的that可省略，后面的that不可省略。 4．The reason for his coming to China was ________ he wanted to study Chinese medicine. A．that B．what
【本讲教育信息】 一. 教学内容： 名词性从句——宾语从句与表语从句 二. 知识精讲 在复合句中起名词性作用的句子叫名词性从句。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、介词宾语等，根据它在句中不同的语法功能，因此名词从句又分为主语从句、宾语从句、表语从句和同位语从句。 （一）宾语从句 1. 概念及引导词 在复合句中起宾语作用的从句叫宾语从句。引导宾语从句的连接词有连接代词（who, whom, whose , what , which, whoever , whatever, whichever ）、连接副词(when , where , how, why )及从属连词(that , whether, if ). 例：John said （that）he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。 I am glad that you are satisfied with your job. 你对工作满意我感到很高兴。 She will name him whatever she wants to. 她高兴给他起什么名字就起什么名字。 That depends on where we shall go. 那取决于我们去哪儿。 2. 宾语从句的种类 常见的宾语从句有动词的宾语从句、介词的宾语从句和形容词的宾语从句三种。 （1）动词的宾语从句 They know that the habit may kill them.定语从句 他们知道这个习惯会害死他们。 They doubt whether or not Jack is a good student. 他们怀疑Jack是否是一个好学生。 They wanted to see which shops offered the best advice and service定语从句. 他们想了解哪家店提出的建议和提供的服务最好。 （2）介词的宾语从句 一般情况下介词后只能接wh- 类连接词引导的宾语从句，但but, except, besides等后可接that引导的宾语从句。 We are talking about what we’ll do next. 我们正在讨论下一步做什么。 I know nothing about him except that he lives here. 对于他，我只知道他住在这儿，其他一无所知。
※※※ 主语从句： 1. What he needs is the shirt of a happy person to wear. 2. What his father said made him think carefully. 3.

宾语从句和表语从句详解 名词性从句指的是在整个句子中起名词作用的从句。这种从句可以做主语、宾语、表语、同位语等，所以这类从句包括主语从句、宾语从句、表语从句和同位语从句。各种名词性从句的结构都是相同的，即由if，whether，that和各种疑问词充当连接词，后接陈述语序。 例如：What they are doing seems very important．（主语从句） 他们在做的事似乎很重要。 My hope is that he will be the best student in the class．（表语从句） 我的愿望是他能够成为班上最好的学生。 Nobody knows who he is．（宾语从句） 大家都不知道他是谁。 I don't like the idea that money is everything．（同位语从句） 我不喜欢金钱就是一切这一观点。 引导名词性从句的连接词中，除了that，if和whether之外其它的都作从句中的一个成分。 【宾语从句】 在句子中作动词或介词宾语的从句叫做宾语从句。引导宾语从句的词有连词that，whether，if；连接代词who，which，what以及其强调形式whoever，whichever，whatever；连接副词when，where，why，how等。 例如：Do you know where the Greens live I have no interest in how rich he is． 宾语从句主要用于下面五种结构： 1．由that引导的宾语从句（that 引导宾语从句时，特别是在口语中可省略） The boy believes that he will travel through space to other planets． that引导的宾语从句多用于say，think，insist，wish，hope，demand，imagine，wonder，know，suppose，see，believe，agree，admit，deny，expect，explain，order，command，feel，dream，suggest，hear，mean，notice，prefer，request，require，propose，declare，report等后。 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。例如：I don’t think it is right for him to treat you like that．（＝I think it is not right for him …．） that不能省略的情况： （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。如： 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一般不可省。如： Just then I noticed，for the first time，that our master was wearing his fine green coat and his black silk cap． （3）当that从句是双宾语中的直接宾语时，that不可省。如： I can’t tell him that his mother died． 2．由特殊疑问词引导的宾语从句 这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。用于这种结构的动词常常是：see，say，tell，ask，answer，know，decide，show，find out，imagine，suggest，doubt，wonder，discover，understand，inform，advise等。
语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：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 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： 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。 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（4）It + 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 a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 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。
宾语从句和表语从句 一、宾语从句要点归纳 ★宾语从句的语序必须是陈述语序。 ★that在引导宾语从句时无词义，也不充当任何成分，且通常可以省略。但如果含有两个或两个以上的并列宾语从句时，通常只有第一个从句的that可以省略，其余从句的that一般不能省略。如： My uncle said (that) he would come and that he would also bring his son. ★whether和if都意为“是否”，通常情况下，二者都可以引导宾语从句；但在介词之后或与or not连用时，只能用whether。注意：当whether与or not 不连在一起时，口语中可用if取代whether，当然也可以用whether。如： I don't know if / whether there will be trains any more. They are worrying about whether they can get there in time. I don't know whether or not I should take his advice. I'm not sure if / whether the train will arrive on time o r not. ★有时可用it作形式宾语，而把真正的宾语从句后置。如： We have made it clear that we will learn to deal with var ious difficult problems. ★在第一人称I / we与动词 think, expect, believe, guess, suppose等连用，后接宾语从句时，通常将从句的否定转移到主句谓语动词，形成否定前移。如： I don't suppose you're used to this diet. 二、表语从句要点归纳 ★表语从句一定要用陈述语序。 ★可接表语从句的词除系动词be外，还有 appear, become, look, remain, seem, sound等连系动词。如：
考研英语主语从句翻译方法 一、关联词或从属连词位于句首的从句+主句谓语+其他成分 它们一般是译在句首，作为主从复合句的主语。这样的词有关联词what, which, how, why, where, who, whatever, whoever, whenever, wherever及从属连词that, whether, if.如：What we now will describe is how the magnetic nature of iron oxide can uniquely be exploited as a separation process utilizing a magnetic filtration system. 参考译文：现在我们所要介绍的是如何奇特地利用氧化铁的磁性而提出一种使用磁力过滤系统的分离法。 分析：其中关联词可译为：...所。 二、it+谓语+that(whether)引导的从句 如果先译主句，可以顺译为无人称句。有时也可先译从句，再译主句。如果先译从句，便可以在主句前加译"这"。如： It can be seen that precleaning alone would not reduce the total sulfur content of the four coals to levels anywhere near the standards. 参考译文：可以看出，这四种煤的总含硫量仅靠预先洗选将不能降低到完全接近标准规定的水平。 It is a matter of common experience that bodies are lighter in water than they are in air. 分析：有时为了使译文成分完整，可以补充上泛指的主语（如人们...、大家...）。 参考译文：物体在水中比在空气中轻，这是一种大家共有的经验。类似的结构还有：it is (universally) known that...大家都知道...it is believed that...人们都相信...
主语从句和表语从句 知识点 1.名词性从句引导词的选择 选择原则“缺什么，补什么，什么不缺，用that” “什么不缺，用that”的意思是：如果从句中不缺任何成分，而且句意完整时，就用that来引导主语从句或表语从句以及其他的名词性从句。 2.whether 意为“是否”，引导的主语从句放在句首，不能用if 代替；但当用 it 作形式主语时，whether引导的主语从句放在句中或句末，此时可换用if. It is doubtful whether there’ll be any seats left.说不上是否还有座位了。 3.that 引导主语从句时，只起连接作用，不作任何成分，没有实际意义。在句 首时不可省略。What引导主语从句时既要起连接作用，又要在从句中作主语或宾语，在任何情况下都不能省略，它具有具体意义，表示“什么，所…… 的（事、物、话）”，相当于all that/ everything that. Which引导主语从句也作成分，它表示选择的意义，常译为“那个”。如：That he survived in the earthquake is a miracle. 他在地震中幸免于难，这是个奇迹。 4.关系代词what, which, who引导主语、表语从句时含有疑问意义，而whatever, whichever, whoever在引导名词性从句时，往往比what, which, who更强调，不表示疑问意义。而且whatever=all that/everything that; whichever=anything that; whoever=anyone who.另外，whatever=no matter what时引导状语从句。如：Whatever is worth doing at all is worth doing well.凡是值得做的事情都值得好好地做。 I语法填空。使用正确连接词补全下列句子。 1.They lost their way in the forest and ______made matters worse was ______ night began to fall. 2.______ drives after drinking should be punished. 3.It is said ______ Peter will have a chance to travel abroad next month. 4.______ we fear when traveling in summer is the sudden change of weather. 5.______ we will go camping tomorrow is up to you. 6.I read about it in some book or other, does it matter ______ it was? 7.______ of you comes in will be given a prize.
表语从句与主语从句 表语从句和主语从句以及宾语从句都要用陈述语序。 Ⅰ.表语从句 在复合句中，位于系动词之后作表语的从句称为表语从句。它位于主句的系动词之后， 最为重要的是我们应该为牛找到足够的水。 The doubt is who has taken away the valuable vase. （主语，人） 疑点是谁拿走了那只贵重的花瓶。 My topic today is what most scientists are researching.（宾语，物，没有选择范围） 我今天的话题就是大多数科学家正在研究的课题。 The problem is which school will be chosen.(which在从句中作定语) 问题是哪一所学校将被选中。 All this was over twenty years ago，but it’s as if it was only yesterday. 这都是20多年前的事了，但宛如昨天一样。 表语从句中应注意的问题 (1)because，why引导的表语从句。 because引导表语从句时，表示“因为”，why引导表语从句时，表示“……的原因”，相当于the reason why。 That’s because he didn’t understand me. (That’s because...强调原因) 那是因为他不理解我。 That’s why he got angry with me. (That’s why...强调结果) 那正是他对我生气的原因。 (2)what引导的主语从句表示结果或名词reason作主语时，后面的表语从句表示原因时要用that引导，不宜用because。 What cost him his life was that he was too careless. 使他丧命的原因是他太粗心了。 The reason why I was sad/for my being sad was that he didn’t understand me. 我难过的原因是他不理解我。 (3)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中，谓语动词需用“should＋动词原形”表示，should可省略。常见的词有：advice，suggestion，order，proposal，plan，idea，request，requirement等。 My suggestion is that we (should) have a discussion about this matter instead of just laying it aside. 我的建议是我们应当讨论一下这个问题，而不应该把它放在一边。 （4）as if/as though引导的表语从句常置于系动词look，seem，sound，be，become等后面，常用虚拟语气，即形式常用过去式的某种时态。
主语从句 一、翻译下列句子 1.That he is still alive is a wonder. 2.That we shall be late is certain. 3.That he should have ignored the working class was natural. 4.That you are coming to London is the best news 5.Whether it will do us harm remains to be seen. 6.Whether they would support us was a problem. 7.Whether they would support us was a problem. 8.When we arrive doesn't matter. 9.When we shall hold our sports meet is not decided. 10.How it was done was a secret 11.How this happened is not clear to anyone. 12.How many people we are to invite is still a question. 13.Where I spend my summer is no business of yours. 14.What we need is money. 15.What I want to know is this. 16.What he says is not important. 17.What make the river more beautiful are the lotus plants growing in the water. 18.What struck me was that they have all suffered a lot. 19.It's a pity that he didn't come. 20.It is important that he should know about this. 21.It's unfair that so many people should lose their jobs. 22.It's amazing that she should have said nothing about it. 23.It's unthinkable that they should deny my request. 24.It seems that you are right. 25.It was clear his words pleased her. 26.It doesn’t matter much where we live. 27.It was a problem whether they would support us. 28.It remains to be seen whether it will do us harm or good. 29.It is said that he’s got married. 30.It is believed that he will win the match. 31.It is reported that Chinese team got 102 golden medals. 32.Whoever pollutes the environment should be punished. 33.Whatever he did was right.
名词性从句 在复合句中起名词作用的从句叫做名词性从句。名词性从句的作用相当于名词，因此主语从句、表语从句、宾语从句和同位语从句分别作主句的主语、表语、宾语和同位语。主语从句：Who will win the match is still unknown. 宾语从句：I want to know what he has told you. 表语从句：The fact is that we have lost the game. 同位语从句：The news that we won the game is exciting. 引导名词性从句的连接词可分为三类： 连接词(不充当从句的任何成分)：that ,whether ,if 连接代词：what, who, whom, whose, which, wh+ever 连接副词：when ,where ,how ,why Object Clauses 宾语从句 一、宾语从句的概念：宾语从句在复合句中作主句的宾语。 位置：通常放在主句谓语动词（及物动词）或介词之后。 句子结构：主句+连词(引导词)+ 宾语从句 e.g. She asked if these answers were right. We can learn what we do not know. He will talk to us about what he saw in the U.S.A. I don’t know where we will hold the meeting. 通过观察，我们可以知道宾语从句的语序用陈述语序： 连接词+主语+谓语+其他成分 1)Could you tell me______. A. you will get here when B. when will you get here C. get here when you will D. when you will get here 2) Mother asked his son what ______for lunch at school. A. did he had B. does he had C. he has D. he had 3) Pointing to the young plant, he asked me ____ that was the one we had seen in the picture. A. what B. if C. where D. how 二、连接词 1、从属连接词(不充当从句的任何成分)：that ,whether ,if 1）、I hear (that) he will be back in an hour. 2）、I want to know if /whether he will go to the park with us 用it做形式宾语的宾语从句时，it常可以放在动词think, find, consider, believe, feel, make等后作为形式宾语，而真正的宾语——that从句则放在句尾）（此时that一定不可以省略）
雅思阅读考试--主语从句 在复合句中用作主语的从句称为主语从句(subject clause)。引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。如： That they were in truth sisters was clear from the facial resemblance between them. 很明显，她们的确是亲姊妹，她们的脸型很相似。(关联词是从属连词that) Who should be responsible for the senior citizens has been widely discussed in our community. 谁应该对老年人负责这个问题在社区里被广泛讨论。(关联词是疑问代词who) Where we can dispose of the increasing rubbish is a great headache to many governments. 在哪儿处置日益增多的垃圾对很多政府而言是件头痛的事。(关联词是疑问副词where) Whoever pollutes the environment should be punished. 不论谁污染环境都应该受到惩罚。(关联词是缩合连接代词whoever) 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。(关联词是缩合连接副词wherever) 有时可以用it作为形式主语，将真实主语从句置于句末。如： 1.
