高二英语名词性从句

高中英语名词性从句知识讲解以及练习题附答案一、名词性从句概述名词性从句是一种充当名词作用的从句，通常在主句中作主语、宾语、表语或同位语。

它通常由引导词（如that, whether, if, who, whom, whose, which, what等）引导，并且从句中含有一个主语和谓语。

名词性从句的种类有很多，包括主语从句、宾语从句、表语从句和同位语从句等。

下面我们将逐一介绍这些从句。

二、主语从句主语从句作为一个名词，通常位于句首，是一个句子，主要作用是作为主句的主语。

引导主语从句的词：What (什么)；Whether (是否)；If (是否)；That (那个)。

例句：What he said is true. (他说的是真的。

)Whether it will rain tomorrow is uncertain. (明天是否会下雨还不确定。

)If you go, I will go too. (如果你走，我也跟着走。

)That he is coming is good news. (他来的消息是好消息。

)注意：主语从句的谓语动词通常要用单数形式。

What引导的主语从句通常用来表示“事物”的概念。

三、宾语从句宾语从句是一个名词，通常位于主句的动词后面，作为主句的宾语。

它可以由常见的宾语从句引导词引导，例如whether, if, that, who, whom, whose, what, when, where, how等。

引导宾语从句的词：Whether (是否)；If (是否)；That (那个)；Who (谁)；Whom (谁)；Whose (谁的)；What (什么)；When (何时)；Where (何处)；How (如何)。

例句：I know that he is coming. (我知道他要来。

)I wonder if he is telling the truth. (我想知道他是否说了真话。

引导名词性从句的连词有三类：that；whether; wh-疑问词。

例句：1.The result of this French influence was that the English language ended up with many French words such as table, animal and age.2. They realize that it is of great value to record and teach them to the younger generation.3. I want to tell the reader that these hills and fields are most beautiful, with many small and clear rivers, and rich fields bearing fruit and grain.4. Some people feel that Wales is an ancient fairy land.5. What interested him was that the whole world had been mapped 70 years before Columbus.6. What is certain that the book has made many people think about the achievements of Zheng He and other Chinese captains and their role in discovering the world.7. That most of these are now threatened and may disappear is a serious matter to the people in Britain.8. This gave him the idea that the Chinese perhaps first discovered America.（二）同位语从句在名词idea; fact; news; thought; suggestion/advice; problem; proof等词后面带上that+陈述句这部分从句解释了前面的那些名词所指的内容，与那些名词起着同等作用的句子成分，叫同位语从句。

C.go
D.were allowed to
同位语从句和定语从句的区别:
如果that作从句中的某一成分,则是定语从句,如 果that不作从句中的任何成分,则是同位语从句.
(1). I had no idea that it was too late.
(2).I still remember the place that we visited last year.
在同位语从句中当名词为advice、 order、suggestion、proposal时， 后面的同位语从句应使用虚拟语 气，谓语v.用（should）＋V.。
1.The suggestion thBat he _____ at the
meeting was agreed to by most people.
(3)由疑问词who，what， where，when, how等引导。
eg:1.The question who should do the work requires consideration .
2.We haven’t settled the question where we are going to spend our summer vacation.
egs：I’ve no idea that Kate has been to shanghai.
同位语从句
The book (that) I bought yesterday was written by LuXun.
定语从句
He can’t answer the question how he got the money.
主语从句 （the subject clause)

规律一：名词性从句在句中要用陈述语序
II．引导词的选择
1. ____ we can't get seems better than ____ we
have. A.What , what C. That , that
B. What , that D. That , what
2. It worried her a bit ____ her hair was turning grey. A．while C．if B．that D．for
规律四：主语从句和宾语从句在适当的情况 下可以借助 “it” 而后置。
1.主语从句可以用it （作形式主语） 来替换成以下几种结构表达。 (A)It is clear/certain/likely /true/surprising that… （B）It is a pity/shame /good idea/no wonder that ...
The question of whether they are male or female is not important. I have not decided whether to go or not.
⑥ whether可引导一个让步状语从句表示 “不管”、“无论”，而if不能，但可以 引导一个条件状语从句表示“如果”如：
• (4)同位语从句 • 就是在句中作同位语的从句。它通常有放在thought, idea, news, word(=news), plan, doubt, question, fact, suggestion, belief等抽象名 词的后面，说明这些词的具体内容或含义。同位语从句大多由that引 导，也可由whether, how, when, where, why等引导，但不能由which 引导。如： • The idea that the earth is round is not a new one. “地球是圆的”这种 观点并不新鲜。He must answer the question whether he agrees to it or not. 他必须回答他是否同意此事这们一问题。 • I have no idea when he will set out. 我不知他什么时候出发。 • 注：有时，同位语从句并不紧跟在它所说明的词的后面。如： • The whole truth came out at last that he was a wolf in sheep’s clothing. 真相终于大白了，他原来是一只披羊皮的狼。

（完整版）高考英语【名词性从句】专题十名词性从句第一节基本知识与基本概念【什么是名词性从句？】顾名思义，主语从句在句子中作主语。

有时本身出现在主语的位置上，也有时出于句子结构的考虑退到句子的尾部，前面用形式主语it代替。

从句作主语时，谓语动词一般为单数形式。

如: What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.【宾语从句】在句子中作宾语的从句就是宾语从句。

由于这是同学们接触比较早的一种从句，应该问题不大。

所以在近年的高考题中，以宾语从句的知识作为考点的题目较少。

但是，宾语从句也有自己的特殊情况，如介词的宾语，形容词的宾语，宾语从句提前和并列的宾语从句等现象。

如：We assumed that there would be more than 100 guests.He told the police in detail what he saw and heard.Nobody is sure what humans will look like in a million years.That will depend on whether they can get the chance.Whether I will have the time I am not sure at the moment.The conductor complained that we were not gifted in singing and that he would never come again.【表语从句】表语从句的最重要脸谱就是它们应该出现在系动词的后面。

高二英语Unit5名词性从句知识精讲高二英语Unit5名词性从句知识精讲定义：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,主语: His job is importantWhat he does is important.表语: This is his job.This is what he does every day.My idea is that we should help her do housework everyday.名词性从句在复合句中能担任: 主语、宾语(介词宾语)、表语、同位语，因此,根据它在句中不同的语法功能，可分为:主语从句、宾语从句、表语从句和同位语从句。

注意：1.从句一律保持陈述语序。

2. 名词性从句可以表示：事实和问一、引导名词性从句的连接词可分为三类：连接连词：that, whether, if , as if ,because（不充当从句的任何成分，且that 也没有任何意义）连接代词：what, whatever, who, whoever, whom, whose, which.连接副词：when, where, how, why二、名词性从句的注意事况1、what与that 的区别：that 和 what 都可引导所有的名词从句。

但是，what除起连接作用外，还在名词性从句中充当成分，表示说的、做的、想的等内容，可做从句的主语、宾语、或表语。

而that在名词性从句中不充当任何成分，只起连接作用。

Eg.That he stole a bike was true. 他偷了一部自行车是真的The important thing is what you do , but not what you say .重要的是你做什么，而不是说什么。

Practice:1.what he wants is a book.2. That he wants to go there is obvious.3.The result is that we won the game.4.This is what we want to know.8. I have no idea what he did that afternoon.2．that不可省略的情况：a. 主语从句、表语从句和同位语从句b.用it做形式宾语的宾语从句c.并列的宾语从句中的后几个从句的引导词that 不能省略3、whether 和 if 的区别是: （在下列情况下，whether 不能被if 取代）a. 主语从句b. 表语从句Unit4c. 同位语从句e. 介词后的宾语从句只能用“whethr”, （一般可以互换）f. whether to do 做动词宾语不能用if to do.（whether也可与动词不定式连用但if不能）g .whether or not 连在一起引导宾语从句时不用if.名词性从句作：一、主语从句：从句在句中充当主语成分，1. 通常放在主句谓语动词之前 *Eg.1).

完整版)高中英语名词性从句详解名词性从句可以作为主句的主语、表语、宾语和同位语。

它们分为主语从句、表语从句、宾语从句和同位从句。

宾语从句作为复合句中的主句及物动词的宾语，也可以作为介词或某些形容词的宾语。

它不担任成分，只起连接作用。

连接词可以是从属连词、关系代词、关系副词。

从属连词包括that、whether、if；关系代词包括who、whom、whose、what、which；关系副词包括when、where、why、how。

这些词既担任成分，又起连接作用。

宾语从句的例子有：I think (that) you will like the pictures。

He has e what he wanted to be ten years ago。

I don’t know why Jane was late for school this morning。

The teacher is pleased with what she said。

I'm afraid that I can't go to the party.在宾语从句中，由that引导的从句可以省略，但如果从句是并列句时，第二个分句前的that不可省略。

另外，宾语从句中的时态要与主句呼应，如果主句动词是过去时态，从句则要用相应的过去时态。

如果从句表示的是客观真理、科学原理或自然现象，从句仍用现在时态。

如果主语谓语动词为think、consider、suppose、believe、expect、guess、imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定式。

XXX。

It is often said that traveling broadens the mind。

I XXX I was determined to carry out the plan。

I consider it XXX。

（表语从句）
3、He want to know who she is / who she has seen .
（宾语从句）
“who”----“ __谁__”作、主__表__宾_成语份、起__连__接__作用
“who”---“谁”、作主 宾 表语、起连接作用
1、Who will go to the college is still uncertain .
“how”----- “如何”、作状语、起连接作用
总结：引导名词性从句的三类关联词
1. that , whether/ if (在从句中不做成分，只 起 连接作用)
2. what who which whose (在从句中做主、表、 宾、定成分)
3. when why where how(在从句中做状语)
1、English is very useful for us . 2、The subject I am interested in is English. 3、We need to master English well. 4、He want to learn the language , English .
用that / what填空：
1.__W__h_a_t he wants is a book. 2. __T__h_a_t he wants to go there is obvious. 3.The result is ____th_a_twe won the game. 4.This is ___w_h_awt e want to know. 5. I have no doubt ___t_h_aht e will come. 6. I have no idea ___w__hahte did that afternoon.

当that从句与另一名词性从句并列做宾语时， that不能省略。 Everyone could see what was happening and that she was really worried. 大家都看得 出发生了什么事，也知道她真得十分焦急。
重点：句中若有两个并列的that 从句做宾语， 即使省略了第一个that，也不可以省略第二 个that。 Eg. I believe (that) you’ve done your best and that things will improve. 我想你已经尽 力了，我相信一切会好起来的。
Whichever (of you) comes in first will receive a prize. （你们之中）哪一个最先到 达将得到奖品。
3) 连接副词when（什么时候）； where（在 什么地方）； wherever（无论哪里）； why （为什么）；how（怎样）以及与how 组成 的短语how long（多长时间）； how often （每隔多久）； how soon（多久以后）； how far（多远）；how many /how much （多少）等
Virtue is whatever one must possess first. 品德应是一个人必须首先具备的。
The difficulty was how he could prove his ideas to other scientists. 困难在于他怎样才 能向其他科学家证实他的想法。
2) 连词whether 或if（是否）whether 可与if互换。 但如果做介词的宾语时，或是宾语从句提置句首时 只能用whether,不能用if引导这个宾语从句。 Eg. I’ll go to that shop and see whether/if they have a telephone. Everything depends on whether you have enough money. Whether he is an expert, I don’t mind. 如果whether 后紧跟or not, 不能用if; whether 与or not分开，可用if. Eg. They doubt whether or not Jack is a good student. They doubt whether/if Jack is a good student or not.

高二英语语法名师讲解：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。

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(好像)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)。

二、主语从句1. 主语从句在复合句作主语。

e.g. Who will go is not important.2. 用it作形式主语，主语从句放在句末。

e.g. It doesn…t matter so much whether you will come or not.3. that引导主语从句时，不能省略。

e.g. That he suddenly fell ill last week made us surprised.三、表语从句1. 表语从句在复合句中作表语，位于系动词之后。

e.g. The question was who could go there.2. 引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.四、宾语从句1. 宾语从句在复合句中作宾语。

名词性从句名词性从句的考查要点：(1) What ,that 引导名词性从句的区别;(2) Whether ,if 引导名词性从句的区别;(3) 同位语从句和定语从句的区别；一、 名词性从句概述在句子中起名词作用的句子叫名词性从句(Noun Clauses ）。

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、和同位语，因此根据它在句中充当不同的语法功能，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。

二、名词性从句比较请注意1、名词性从句中的that 省略情况：动词后的宾语从句和表语从句中的that 可以省略。

2、No matter +wh-开头的词如no matter what 等只能连接让步状语从句。

而wh-开头的词+ever 如whatever 等既能连接让步状语从句，也能连接名词性从句。

解题步骤和原则：分析复合句结构，找出从句，确定名词性从句中的哪一类。

分析从句，结合上表中各个连接词的特点，缺什么补什么。

主语从句应注意的问题主语从句中It 作形式主语常用句型：1. It + be +形容词（obvious, true, natural, possible, likely, probable, certain,wonderful, good, etc.） + that 从句2. It + be +名词词组(no wonder ，a pity ，an honor, a good thing, no surprise , etc.) +that 从句3. It + be + 过去分词(said, thought, reported, expected, announced, decided , etc.)+ that 从句4. It +不及物动词(seem, happen, etc.) + that 从句5. It doesn’t matter(make no different, etc.) + 连接代词或连接副词引导的主语从句Eg: It is certain that she will do well in her exam.Eg形式主语主语从句1.(2012课标·全国I) It is by no means clear__________ the president can do to end the strike.A.howB. whichC. thatD. what2.(2012天津，7) It doesn’t matter _______you turn right or left at the crossing — both roadslead to the park.A. whetherB. howC. ifD. when3.(2012江西，25) It suddenly occurred to him_________ he had left his keys in the office.A. whetherB. whereC. whichD. that宾语从句应注意的问题1. if /whether表示“是否” 可以互换,但以下情况只能用whether，不用if. （1）在介词后面Eg：Everything depends on whether we have enough time.（2）与or not连用Eg：I don’t know whether he will come or not.（3）宾语从句提前时Eg：whether they can come here on time, we don’t know.（4）后面跟不定式Eg：I really don’t know whether to accept or refuse.2. 宾语从句的时态（一般来说，主从句时态要统一。

高二语法-名词性从句专讲名词性从句是由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 happen ed 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。

(2) It is said , (reported) …结构中的主语从句不可提前。

例如：It is said that President Jingo will visit our school next week. (right)That President Jiang will visit our school next week is said. (wrong)(3) It happens…, It occurs… 结构中的主语从句不可提前。
