高中英语语法（2）主语从句★背诵要点：1、主语从句是指主语用一个从句来表达的句子，也就是说在谓语动词前面的部分是一个从句的句子是主语从句。
2、主语从句的引导词有：1）连词：that, whether2）连接代词：who, what, which, whose, whom3）连接副词：where, when, how, why3、主语从句使用正常主谓语序，不能用倒装语序。

5、that在主语从句中不能省略。
例如：What he said is hard to understand.Where he has gone is unknown to us all.That you find this exercise difficult is quite natural.It is quite natural that you find this exercise difficult.★注意要点：1、引导词that与whatwhat既有引导主语从句的作用,同时又在从句中作成分,这时what相当于all that或everything that...,常译成"所……的(东西、事情、话等.)";而that只起连接作用,本身无实际意义,在从句中也不担当任何成分.但that引导的主语从句放在句首时,不能省略that.例如:What is done can't be undone. (谚语) 已成定局, 无可挽回.2、引导词if和whether表示是否的意思时，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、熟记以下变化Whoever=no matter who=any one whoWhichever=no matter which=any one whichWhatever=no matter what=anything that★基础题练习：1．_______your father wants to know is________ getting on with your studies.A.

(完整版)主语从句详解
主语从句详解一、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、主语从句主要有四类（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.That you are so indifferent bothers me.That she survived the accident is a miracle.（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. 注意：引导主语从句, 不能用if, 只能用whether.例如：Whether we will hold a party in the open air tomorrow depends on the weather.Whether she is coming or not doesn’t matt er too much.（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. What I want to know is this.Whatever we do is to serve the people.注：whatever / whoever的功用whatever, whoever在主语从句中不含疑问意义.它引导主语从句, 并在从句中作主语、宾语、表语等.whatever = anything that; whoever = anyone who.要注意和whatever, whoever引导的让步状语从句的区别.Whoever breaks the law should be punished. （主语从句）（＝Anyone who breaks the law should be punished. ）Whoever breaks the law, he should be punished. （让步状语从句）（＝No matter who breaks the law, he should be punished. ）（4）用连接副词when, where, why, how引导名词性从句(其连接副词有含义,在句中作状语.) 例如:Where we should leave it is a problem.When they will come hasn’t been made pubic.三、注意点: it构成的主语从句（1）由连词that引导的主语从句, 在多数情况下放到句子的后面, 而用代词it作形式主语. 例如：That light travels in straight lines is known to all.=It is known to all that light travels in straight lines.When the plane is to take off has not been announced .= It has not been announced when the plane is to take off.(但当what引导的主语从句表示“…的东西”时, 一般不用it作形式主语.)错:It is a book what he wants.对:What he wants is a book.另外, 需要注意的是, it作形式主语代替主语从句时, 要注意和as引导的定语从句的区别.试比较：It was reported that the US was under the terrorist attack.As was reported, the US was under the terrorist attack.（2）常见用it作形式主语的复合句结构A. It is +名词+从句It is a fact that… 事实是……It is good news that … ……是好消息It is a question that … ……是个问题It is common knowledge that … ……是常识类似的名词还有：a pity；a wonder；a good thing；no wonder；surprise等.例如：It is a mystery to me how it all happened.It is common knowledge that the whale is not a fish.It is no surprise that Bob should have won the game.It’s a pity that you missed the film.B. It is +形容词+从句It is necessary that … 有必要……It is clear that … 很清楚……It is likely that … 很可能……It is important that … 重要的是……类似的形容词还有：Strange; natural; obvious; true; good; wonderful; possible; unlikely; quite; unusual; certain; evident; worth-while; surprising; interesting; astonishing, etc.例如：It is doubtful whether she will be able to come.It was really astonishing that he refused to talk to you.It is essential that he should be here by the weekend.It seems obvious that we cannot go on like this.It is necessary that you （should）master the computer.It is important that a student learn English well.It is likely that a hurricane will arrive soon.需要注意的是, 这类主语从句中, 谓语动词很多为“（should）＋动词原形”, 即要用虚拟语气.C. It is +过去分词+从句It is said that … 据说……It is reported that … 据报道……It has been proved that … 已证明……It must be pro ved that… 必须指出……类似的过去分词还有：known; estimated; expected; believed; thought; hoped; noted; discussed; required;decided; suggested; demanded; made clear; found out,etc.例如：It is thought that he is the best player.It is estimated that the vase is 2000 years old.It is used to be thought that a new star must be due to a collision between two stars.It has not been made clear when the new road is to be opened to traffic.It is said that he was killed in the earthquake.D. It seems（happened / appears / doesn’t matter / makes no difference / occurred …）that …It seems that they will win the game.It makes no difference whether he will attend the meeting or not.It does not matter if I missed my train.It happened that I saw him yesterday.主从练习1. _____ as much as one-fifth of all timber harvested is not used.A.

What; becauseB. What; thatC. That; whatD. That; because［答案］ B［解析］第一个下划线处的引导词引导主语从句并在该主语从句中充当主语, 特指令校方骄傲的事情, 应选用关系代词型的引导词what；第二个下划线处引导表语从句表示原因、理由, 应由that引导对应的名词性从句.［考题6］—Are you still thinking about yesterday’s game?—Oh, that’s ____.A. what makes me feel excitedB. whatever I feel excited aboutC. how I feel about itD. when I feel excited［答案］ A［解析］A选项的意思是“令我感觉激动的事物”；B选项的意思是“我觉得激动的任何事物”；C选项的意思是“我对它感觉的方式”；D选项的意思是“令我感觉激动的时间”.四个选项中A最适合跟代表“game”的主语that对应, 充当表语从句.表语从句与宾语从句的关系不属于的宾语从句和表语从句都属于名词性从句.其作用跟名词在句中的作用相同.故充当宾语的句子叫宾语从句, 充当表语的句子叫表语从句.宾语从句(1)对于宾语从句要掌握以下三点①语序: 从句的语序必须是陈述句语序, 即“主语+ 谓语”这种形式.②时态: 当主句是一般现在时或一般将来时的时候, 从句可以是任何时态, 而当主句是一般过去时的时候, 从句, 从句时态必须是过去时范围的时态, 即(一般过去时, 过去进行时, 过去完成时, 过去将来时).③连接词: 当从句意思完整, 主句意思肯定时, 连接词用that, 且可以省去, 当从句意思完整, 主句意思不确定或含否定含意时, 常用if或whether(是否), 当从句意思不完整时, 连接词则是代替不完整部分的特殊疑问词.表语从句在句子中起表语作用的从句叫做表语从句, 位于主句系动词的后面.表语从句的引导词和主语从句的引导词相同.也是名词性从句的一种.如：What the police want to know is when you enred red the room警察想知道的是你什么时候进的房间.The The trouble is that we are short of funds困难是我们缺乏资金.This This is what we should do这是我们应当做的.That”s s why I want you to work there那就是我要你在那儿工作的原因.His His first question was whether Mr. Smith had arrived yet他的第一个问题是史密斯先生到了没有.注意：从句中的疑问句用正常语序, 即陈述语序.as as if, as though, becau也可用来引导表语从句.She She seems as if she had done a great thing她看起来好像做了一件大事.It It is because you eat too much那是因为你吃得太多了.表从练习一1.

2023年高中英语语法主语从句用法汇总
2023年高中英语语法主语从句用法汇总语法知识：表语从句用法汇总表语从句是名词性从句的一种，也是往往最令大家迷糊的一种，很多人都弄不清标语的概念，因而也弄不清表语从句的用法1. 由关系代词型what引导That’s what I want to stress. 这是我想强调的。

1. that在引导表语从句时无含义，不作成分，通常不省。
高中英语知识点归纳主语从句的种类与用法
高中英语知识点归纳主语从句的种类与用法主语从句是英语语法中的一个重要知识点。
它是由一个句子成为一个句子的主语，可以用来替代一个名词性成分作为整个句子的主语。
主语从句的种类与用法可以通过以下几个方面进行归纳。
一、宾语从句宾语从句是主语从句中最常见的一种类型。
宾语从句通常用来当作动词的宾语，表示主句中的某个动作或状态所作用的对象。
常见的动词有think、believe、know、want、hope等。
例如：1. I believe that she will come back soon.（我相信她很快会回来。
）2. He asked if she could help him.（他问她是否能帮助他。
）二、表语从句表语从句用来修饰主句中的主语或宾语，起到对主语或宾语进行补充或说明的作用。
常用的动词有be、seem、appear、look等。
例如：1. The problem is that he has no money.（问题是他没有钱。
）2. My dream is to become a doctor.（我的梦想是成为一名医生。
）三、同位语从句同位语从句用来对主句中名词性成分进行解释或进一步说明。
同位语从句通常出现在一些特定的名词后面，例如fact、news、idea等。
例如：1. The news that he passed the exam made us all happy.（他通过了考试的消息让我们都很高兴。
）2. The fact that she lied to me disappointed me.（她对我撒谎的事实让我很失望。
）四、定语从句定语从句用来修饰主句中的名词或代词，并对其进行限制或说明。
定语从句通常出现在被修饰的名词或代词之后。
例如：1. The book that I borrowed from the library is very interesting.（我从图书馆借的书非常有趣。
2023年高中英语语法精讲之主语从句详细讲解
2023年高中英语语法精讲之主语从句详细讲解主语从句结构及用法在句子中担当主语的从句就叫做主语从句，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。
通常结构为“引导词 + 主语 + 谓语 + 其他成分"。
一. 概念：在句子中担当主语的从句就叫做主语从句，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。
主语从句使用陈述语序，其通常结构为“引导词 + 主语 + 谓语+ 其他成分", 但当连接代词同时充当从句主语时，其结构为“连接代词 + 谓语 + 其他成分”。
二. 引导词：1. that引导eg. That you are coming to London is the best news I have heard this long time.2. whether引导eg. Whether they would come to conference was a question.3. 连接代词引导: who,whom, whose, what, which, whoever, whomever, whichever, whatevereg. Whoever is top from wins the game when two matched players meet.4. 连接副词引导: therefore, besides, otherwise, however, moreover, still, thus, meanwhileeg. How this happended is not clear to anyone.5. 关系代词型what引导三. 形式主语it:1. 对关系代词型what引导的主语从句，可以使用形式主语。
eg. It is clear enough what he meant.2. 如果句子是疑问句，则必须用带形式主语it的结构.eg. Is it true that all of us need to to conference?主语从句有哪几类如果一个句子在复合句中充当一个主语,那么这个句子就是主语从句。
高中英语：从句语法知识大梳理
高中英语：从句语法知识大梳理从句的基础概念由一个主句和一个或一个以上从句构成的句子叫做复合句。
所谓主句，就是在复合句中起统领作用的句子，它是全句的主体，通常可以独立存在；而从句则是复合句的一个句子成分，不能独立存在。
如：You’ll feel better after you take the pills. 吃完药丸后你会感到好一些。
主句是You’ll feel better，从句是after you take the pills，由after引导，在整个复合句中用作状语，表示时间。
注意，英语的复合句不是简单句的反面，不要将它误解为“复杂句”。
事实上，英语的简单句有时也可以比较“复杂”，而复合句也可以比较“简单”。
如：He stopped because he was tired. 他停下来是因为他累了。
这个句子比较“简单”，却是一个典型的复合句，其中的he stopped是主句，because he was tired是从句，在复合句中用作状语，表示原因。
从句的分类一般说来，一个从句在复合句充当什么成分我们就叫它为什么从句——从句在复合句用作主语，我们就叫它为主语从句；从句在复合句用作宾语，我们就叫它为宾语从句等。
如：He answered that he knew nothing about it. 他回答说他不知情。
that 引导的从句在复合句中用作动词answered的宾语，因此为宾语从句。
The trouble is that I have lost his address. 麻烦的是我把他的地址丢了。
be动词后做表语从句He was rather pleased when he won that prize. 他获奖后相当高兴。
用状语表时间，也叫时间状语从句。
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。
【高中英语】高中英语知识点：主语从句
【高中英语】高中英语知识点：主语从句主语从句的概念：如果一个句子在复句中充当主语，那么这个句子就是主语从句。
主语从句通常由下列连词引导：which、if和连接代词what、who、who、who和how、when、where、why和其他副词。
在句子中没有词义，只起到连接作用。
主语从句用法：1.主语从句的引导词：主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导：他还活着真是个奇迹。
whenwearrivedoesn'tmatter.什么时候到没有关系。
什么是钱。
我们需要钱。
whatiwanttoknowisthis.我想知道的就是这一点。
他们是否支持是个问题。
他们是否会支持我们仍然是个问题。
2、主语从句与形式主语it：有时为了考虑句子的平衡，我们通常在主语从句中使用正式主语，把真正主语从句移到句子的末尾。
有三种情况：(1)对于以连词that引导的主语从句，通常用形式主语代主语从句：（2）对于连接代词（副词）引导的主语从句，可以用形式主语代替主语从句，也可以在句首直接使用主语从句：如：whethertheywouldsupportuswasaproblem.他们是否会支持我们还是一个问题。
他们是否支持我们是个问题。
他们是否会支持我们仍然是个问题。
(3)对关系代词型what引导的主语从句，通常不用形式主语，总是主语从句放在句首：我们需要的是钱。
whatiwanttoknowisthis.我想知道的就是这一点。
（4）如果句子是疑问句，则必须使用带有正式主语的结构：如：isittruethatheisthegirl'sfather?他是那女孩的父亲，是真的吗？你怎么又迟到了？你为什么又迟到了？3、连词that的省略问题：有时引导主语从句的连词可以省略，有时不能省略。
原则是：若that引导的主语从句直接位于句首，则that不能省略；如果受其引导的主语从句位于句末，而正式主语则用在句首，则可以省略：如：thatyoudidn'tgotothetalkwasapity.很遗憾你没去听报告。

2.引导主语从句的词● 连词：that, whether 起连接作用不充当成分，但不能省略That he is a famous singer is known to us.Whether he’ll come here isn’t clear.注意: 由that 引导的主语从句有时为了使句子结构平衡, 避免 “头重脚轻”, 常用 it 作形式主语, 而把从句放在后面。
That he is a famous singer is known to us.It is known to us that he is a famous singer.● 连接代词：what(ever),who(ever), which(ever)，whose 充当主语/宾语/定语等 What many scientists believe is that the earth is round.Whatever was said here must be kept secret.Who will take part in the meeting has not been decided.Whoever breaks the law will be punished.Which student will win is uncertain.● 连接副词：when, where, how ,why 充当状语表时间、地点、方式、原因 When your uncle will arrive was not mentioned in his letter.Where the painter is from is unknown to us all.How we’ll solve the problem should be discussed againWhy you went there alone must be explained to us.3.It 作形式主语的一些固定用法：● It +be + n ( a pity/ a fact/ a good idea/ an honor/ a mystery/ a pleasure/ a shame/ a wonder/ a challenge…) + that 从句e.g. It is a pity that you missed the party .● It +be + adj(certain/ possible/ unlikely/ obvious)+从句e.g. It is certain that we will do a good job.★特殊情况：It +be+adj (important/ essential/ natural/ necessary)+ that sb. should do e.g. It is necessary that we should learn a foreign language● It +不及物动词(happened/occurred to / seems/ matters/ appears…) +从句 e.g. It matters whether he will accept our invitation.● It + be +过去分词(known/ said/reported/ believed/ suggested/ stressed) +从句 e.g. It is known to all that heart attack is terrible.。
