名词性从句之主语从句一、名词性从句概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。
二、主语从句定义：在句中起主语作用的从句称为主语从句。
引导主语从句的连接词主要有：单纯连词(that, whether/ if)、连接代词(what, whatever, who, whoever, whom, whose, which, whichever 等)和连接副词(when, where, why, how, whenever, wherever, however 等)。
1)that引导的主语从句(1)由连词that引导的主语从句:引导词that无含义/在句中不做成分/不可以省。

That light travels in straight lines is known to all.众所周知，光沿直线传播。
That you don’t like him is none of my business.你不喜欢他不管我的事。

名词性从句(宾语从句表语从句主语从句)讲解与练习
名词性从句（宾语从句表语从句主语从句）讲解与练习六大基本句型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句型或许do句型。
可以用以下公式停止表示：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); ④when(whenever)，where(wherever)，why，how(however); ⑤ how many, how much, how long, how often，how soon宾语从句的方式：1、主谓宾句型的宾语从句: 作为名词的宾语扩展成一个be句型或许do句型。
He knows the newsHe knows that the teacher is in classroom2、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。

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.剖析：下面句子中介词前面所跟成分都做介词宾语。
名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。
主语从句表语从句学案和专项练习
Subject Clause and Predicative ClauseⅠ. 主语从句(Subject Clause)一定义：__________________________________________________.1. He is right .2. What he said is right .二.主语从句引导词1.主语从句的引导词与宾语从句一样。
〔但不用if 〔是否〕，只能用whether(是否)〕1) that 2) whether3) what , which ,who, whom, whose, whatever , whichever.....4) where , when , why, how, wherever, whenever .....5) how many , what color, how far等。
2. 引导主语从句的关联词除起连接句子的作用，绝大多数关联词在主从中要充当一定的句子成分。
3. 主语从句的语序是：关联词+S+V三. 主语从句引导词的用法:1. that 的用法：that 引导句意完整, 意义明确不缺成分的述句；无词义，在主从中不充当句子成分，不能省略。
仿照例子改写句子改成相应的主语从句Model: There is life on another planet (在另外的星球上)〔that 引导的主从〕 It is almost impossible.→That there is life on another planetis almost impossible(主从) s v.1). The scientist will give us a lecture ne*t week. It is true. →2). You don’t like him. It is none of my business.(不关我的事) →3).Her hair was turning gray(灰色). It worried her bit.→4). He told her everything. It is probable.→5). He sings so well. It is no surprise.→2. whether 的用法: whether引导的主从不缺句子成分，句意不完整，表达一种不确定，不明确的概念；whether当"是否"讲，在主从中不充当句子成分。
英语从句语法学习学案+经典习题(含答案)
从句讲解：从句及其特点（学案）从句是指在一个句子中充当一个成分的句子，充当什么成分就叫什么从句，如：充当宾语就叫宾语从句，充当定语成分就叫定语从句。
从以上定义中我们可以得出关于从句的一个最大特点：从句是句子。
从句的共同特点：1.从句都有自己的连接词 2.从句都是陈述语序(陈述语序就是主语在前，谓语在后)1.名词性从句在句子中起名词作用的句子叫名词从句。
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。
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如：That she was chosen made us very happy.宾语从句宾语从句是指在一个句子中充当宾语的句子，如：He said that he wanted to be a teacher when he grew up.宾语从句的特点：①宾语从句有自己的连接词②宾语从句用陈述语序③宾语从句的时态①宾语从句的连接词：宾语从句的连接词包括that、if/whether(是否)、特殊疑问词。
②宾语从句的语序;A.宾语从句的连接词后加陈述语序(主语在前，谓语在后),如：I want to know if he can come tomorrowB.当连接词本身又是宾语从句的主语时，后面直接加谓语动词，如：She asked me who had helped him.③宾语从句的时态，只要记住以下口诀“主现则从任，主过则从过，客观真理一般现”A.主现则从任：主句如果是一般现在时，则从句根据时间状语需要从八种时态中任选一种，如：1.He tells me he likes English very much(一般现在时)B.主过则从过：主句如果是一般过去时，则从句根据时间状语需要从四种带“过”字的时态中任选一种，带“过”字的时态分别是如：一般过去时，过去进行时，过去将来时，过去完成时。

高中英语复习主语从句、表语从句专项练习
主语从句CThat the success of humans as a species depends to a large extent on our ability to cooperate in groups is widely believed. Much more so than any other animal, people are able to coordinate and join their forces and actions to produce mutual benefits. New research involving Dr Molleman, an expert at the University of Nottingham, suggests that successful cooperation in groups depends on how people gather information about their peers, and how they base their cooperative decisions on it. Biologists wonder how cooperation could have developed by natural selection: it is puzzling how cooperation can be beneficial when it is possible to behave selfishly and take advantage of the cooperative efforts of your group. Psychologists and economists try hard to understand why many people are willing to sacrifice their own welfare to benefit their social environment. They asked questions like “How do people make decisions when their actions can affect the welfare of others?” “How people determine their behavior when they have to cooperate in groups?”.Dr Pieter Van Den Berg from the University of Groningen said, “From previous research we know that some people are ‘majority-oriented (以……为中心)’ and tend to look at the behavior of the majority in their group, whereas others are ‘success-oriented’ and try to find out what kind of behavior pays off best for themselves.”Dr Molleman, from the center of the Decision Research and Experimental Economics, said, “It turns out that behavior in groups of success-oriented people was much more selfish than it in groups of majority-oriented people. As a consequence, the people in the majority-oriented groups tended to cam more money in the experiment since they cooperated more.”28. Compared with other animals, human beings are capable of ________.A. communicating well with othersB. working together with each otherC. surviving some natural disastersD. getting access to various information29. What are the psychologists and economists most interested in?A. Whether people’s personal efforts will pay off eventually.B. How cooperation has developed over a long lime naturally.C. Why people offer to affect those around them unselfishly.D. What benefit that good cooperation can bring immediately.30. We can infer that the success-oriented people________.A. are careful to select a group to joinB. are likely to be successful in the futureC. pay more attention to the result of their effortD. have some skills in collecting useful information31. What is the new finding of the research?A. Having good relationship gets us to live fullest life.B. Focusing on individual success makes people selfish.C. Being considerate can ensure our long-term benefit.D.

高考英语专项复习：主语从句讲解及练习(附答案)
主语从句讲解及练习主语从句一、概述：在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。
二.主语从句主要有三类：（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。
例如：That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。
That you are so indifferent bothers me.你如此冷淡使我很烦恼。
That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。
（2）用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。
例如：Whether she is coming or not doesn’t matter too much.她来不来都无关紧要。
（3）用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分).例如：What you need is more practice.你所需要的是更多的训练。
What I want to know is this. 我想知道的就是这事。
Whatever we do is to serve the people.我们无论做什么都是为人民服务。
（4）连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。
)eg:Where we should leave it is a problem.When they will come hasn’t been made pubic.他们什么时候来还不知道。
表语从句讲解及练习(最新整理)
表语从句1．定义：用作表语的从句叫做表语从句。
2．引导表语从句的关联词的种类：(1)从属连词that。
在从句中不做成分。
如：The trouble is that I have lost hisaddress.麻烦是我把他的地址丢了。
The reason was that he was late for school.(2)从属连词whether,as,as if。
如：1.He looked just as he had looked ten years before.他看起来还与十年前一样。
2.The question is whether they will be able to help us. 问题是他们是否能帮我们。
注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：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。
The key is whether we can solve the problem.//It looked as if it was going to rain.注：能跟表语从句的谓语动词一般为系动词be, seem, look，sound等。
如：He looked just as he had looked ten years before. 他看起来还与十年前一样。
It sounds as if someone is knocking at the door. 连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。
如：The problem is who we can get to replace her. 问题是我们能找到谁去替换她呢。
