高中英语语法讲义---- 名词性从句（主从、表从、宾从，同从）1，陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。
主从可用it 做形式主语，宾从第一个that 可省略。
You study hard.主从：That you study hard is known to us.= It is known to us that you study hard.表从：My opinion is that you study hard .宾从：I think (that) you study hard. …and that (不能省略)….同从：My opinion that you study hard is known to us. *比较同从和主从！●一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。
I appreciate your idea that we have an exam every week. （that后完整—同从）I appreciate your idea that you came up with last time.（that后不完整---定从）2，一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾从后有or not时只用whether）。
Does your friend like English ?主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English.表从：My question is whether your friend likes English.宾从：I don’t know whether/ if your friend likes English.同从：My question whether your friend likes English isn’t clear.3, 特殊问句做名从用疑问词（连词）+ SV, 疑问词做主语时直接+谓语。
名词性从句（宾语从句、表语从句、主语从句、同位语从句）讲解高考英语语法总复习复合句：主句+从句意思上来讲主句是主要的。
但是从句才是我们学习的重点。
从句有各种各样的变化，从句要作不同的成分的，主句与从句间要加不同的连接词，可能有时候还要倒置。
例句：America's new plan to buy up toxic assets will not work unless banks mark assets to levels which buyers find attractive.America's new plan to buy up toxic assets will not work（这一部分为主句）。
unless从句1前的连接词。
banks mark assets to levels 从句1。
表示条件的从句。
如果...which从句2前的连接词。
buyers find attractive 从句2。
修饰前面levels的定语从句。
（一）名词性从句（当成名词来用的句子）包括：1、宾语从句（最重要）；2、表语从句（最不重要）；3、主语从句（一般重要）；4、同位语从句（一般重要）。
4种从句的写法一样，不一样的是位置不一样。
先看：1、宾语从句（最重要）1）含义：是一个作宾语的句子，位置是把它放到主句里作主句的宾语。
例句：The fossil record shows that many species have endured for millions of years.全句是一个主句，但是that many species have endured for millions of years作了该主句的宾语。
即that many species have endured for millions of years为宾语从句。
2）宾语从句的写法：先写两简单句，其中一个简单句作主句时省略掉宾语，然后将另一个简单句接到作主句的宾语位置当宾语即可，但是要注意连接词的使用。

精锐教育学科教师辅导讲义学员编号：年级：高三课时数：3学员姓名：辅导科目：英语学科教师：授课类型C(名词性从句简述) C (主语从句，表语从句) C (宾语从句，同位语从句) 授课日期及时段教学内容一、专题知识梳理一、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）。
1）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。
2）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。
主语从句What he wants to tell us is not clear.宾语从句He has told me that he will go to Shanghai tomorrow.名词性从句表语从句The fact is that we have lost the game.同位语从句I have no idea when he will come back home.1. 这里重点强调一下同位语从句，顾名思义，所谓同位语从句就是一个句子与主句中某一个名词互为同位语！那么什么是同位语呢，很简单就是相同地位，相同成分，平起平坐，A(名词)=B（从句）, B（从句）=A（名词）, 去掉任何一部分（A/B）对整个句子都不影响。
2. 而且与从句互为同位语的名词一般为抽象名词，例如：advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
二、引导名词性从句的连接词1.引导名词性从句的连接词可分为三类：1.连词：that（无任何词意）whether, if（均表示“是否”）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2. 连接代词：what, whatever, who, whoever, whom, whose, whichever, whomever3. 连接副词：when, where, how, why, how many, how much, how often2. 连接词的判定：根据连接词在从句中所做的不同的成分，我们可以归纳如下：人物主语：who what宾语：whom what名词性从句表语：whom what定语：which what whose状语：when where why how (how many, how much, how often)不做成份：that if/whether as if /as though二、专题过关(一）：1._______ you don't like him is none of my business.2.When asked ____ they need most , the kids said they wanted to feel important and loved.答案：1.That 2. what(二）：______ the meeting will be held in Beijing is not known yet.What the doctors really doubt is _____my mother will recover from the serious disease soon.答案：1.Whether 2. whether(三）：It was ordered that all the soldiers _______to the front.(send)We are all for your proposal that the discussion _______.(put off)答案：1. (should) be sent 2. (should) be put off三、学法提炼1. 从句子结构入手，首先分清楚简单句和复合句。
名词性从句同学们，在第3、4、5单元我们分别学习了宾语从句、表语从句、主语从句和同位语从句。
它们都属于名词性从句。
现在，我们将从下面几点谈谈名词性从句：一、相关概念；二、种类；三、常见引导词；四、七大常考考点：l.that \ what \ which; 2.it形式主语、宾语的用法；3.语序问题；4.同位语从句和定从的区别；5.what \ whatever… 6.if\whether;7.虚拟语气问题；五、相关习题集中练习一.相关概念1. 名词：表示人或事物的名称的词2. 名词的句法作用：名词在句中主要作主语，宾语，表语和同位语。
另外还可以作定语，状语3. 名词性从句：在英语的句子结构中，本来该由名词充当的主语、宾语、表语和同位语，由一个句子来充当，这个句子就叫：名词性从句。
二、名词性从句的种类1. When we will start is not clear.主语从句2. Mrs. Black won ' t belieV hat her son has become a thief.宾语从句3. My idea is that we should do it right now.表语从句4. I had no idea that you were her friend. 同位语从句三、常见引导词:1）从属连词that只引导，本身无意义，仅起引导作用。
（引导宾语从句时可省，但是如果是并列的多个宾语从句，只能省第一个）2）连接代词who, whom, what, which, whoever, whatever, whiche等e，有意义，作成分3）连接副词where, when, how, why等，有意义，在句中作状语4）从属连词if, whether （是否）（if只能引导动词、形容词之后的宾语从句）1. What he said has nothing to do with you.2. When we'start tomorrow will be told soon.3. That he did such a thin gsatisfied me.4. How we can protect cultural relics needs to be discussed.四、名词性从句七大常考考点考点1:A.连接词：that与what的区别What we can ' t get seems better tha h n at we have.That a new teacher will come to our school is true.that只起连接作用，无意义，在从句中不充当任何成分;what既有连接作用，又要在从句中作成分（主语，宾语，表语）（…的东西;物;话;时间;地点;人物擞目等不同概念）1. After five hours drive, they rea Wtedt was called the hometow n of the goddess.2. The other day, my brother drove his car down the street at what was a dangerous speed.3. The village was quite differe nt from what it used to be.4. That the earth is round is known to us all.5. Father made a promis&hat if I passed the exam in ati on he would buy me a computer.B. what （什么）/ which （表选择，哪一个）1. ---Do you know what Mr. Black ' s addres? is---He may live at No. 18 or No. 19 of Bridge Street. I whi o h not sure of2. I read about it in some books or other, does it mattewhich it was?咼考题选萃1) ____ y ou don ' t like him is none of my bus in ess.A. WhatB. WhoC. ThatD.

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。

It’s the third largest state with the largest population in the country. The Indians settled in what we now know as California 15,000 years ago. California used to be ruled by Spain for over two centuries and later became a part of Mexico which had to give it to the US after its failure in the American-Mexican war. That is why today there is still a strong Spanish influence in California. It is in the Gold Rush period that a large number of immigrants from all over the world were attracted to California by the dream of becoming rich. However, what brought most of the Chinese immigrants to California is building the rail network. In the recent decades, California has become home to more people from Asia. We hold the belief that California will become more multicultural in the future.Cloning is an advanced technology with which scientists can create an exact copy of a plant or an animal. Like a coin with two sides, cloning has both advantages and disadvantages. On the one hand, people are excited about the idea that cloning may help us in producing plants and medical research. On the other hand, the fact that cloned animals may die very young frustrated （使…受挫）the scientists. In addition, many people hold the view that human cloning must be strictly forbidden because some moral questions will put us in dilemma(进退两难). We have no idea whether cloning will bring us more benefits than harm.III. Writing task:范文：Once upon a time, there were four blind men. They didn’t know what an elephant looked like, so they were very curious. Luckily, one day, they got good news that they could touch an elephant by themselves. They each got hold of a different part of the giant elephant. The first blind man believed that an elephant was like a fan because he was touching one of its ears. The second blind man who touched its nose held the belief that an elephant was like a rope. The third man said that it was like a pillar after he touched one of its legs. The last man argued that it was like a wall when he touched its body. What an elephant really looked like became their topic of debate（辩论）. The truth is that we should not jump to a conclusion before we get all the details.模仿上文，从下面的题目中任选一个进行描述或者说明，尽量多使用名词性从句1. 成语故事：愚公移山，亡羊补牢，画蛇添足，守株待兔，叶公好龙，刻舟求剑，塞翁失马，孟母三迁2. 校园生活：高中生不应该带手机来学校我最喜欢的科目/老师/同学我参加了学校的艺术节/科技节/运动会……在两年的高中生活中我最大的收获展望未来的高三生活语法复习：名词性从句课堂练习班级_____ 姓名__________ 学号_____句式提升练习：使用含有名词性从句的复合句改写下列句子，每个句子至少写出两种改法。

should+动词原形表示，should可省略。
如：My suggestion is that we (should) start early tomorrow. 我的建议是我们明天一早就出发。
注意：1．what引导“…….+ is + what表语从句”，= “…….+ is + 先行词that ……”，表示“.….是表语从句”例：Raw material is what we are badly in need of.= Raw material is the thing that we are badly in need of.2．when、where、why、whether、how引导“…….+ is +when、where、why、whether、how表语从句”，表示“.….是表语从句”例：That’s where we differ.表语从句中只能用whether表示是否例：The question is whether we can finish our work by tomorrow morning.3．that引导“…….+ is /remain/look/seem/appear + that表语从句”，表示“.….是表语从句”例：What’s troubling me is that I don’t have much experience in this field.主语是reason时，表语从句必须由that引出例：The reason I don’t go there was that I got a new job.4．as if/as through引导“……look/seem/appear/remain（系动词）+ as if/as through 表语从句”，表示“.….好像表语从句”例：It looks as if it is going to rain.（三）宾语从句1．定义：用作宾语的从句叫宾语从句。

如：He is a good student except that he is careless.他是一个好学生，只是有点粗心。
You may rely on it that I shall help you. 你可以指望我会帮助你的。
介词宾语不可以用which来引导，而要用what来引导。

如：I am not sure what I ought to do.我不能确定我该做什么。
4．连词whether (…or not)或if引导的宾语从句if和whether引导的宾语从句可以互换使用，但whether常和or not连用，if一般不与or not 连用。
