知识点01 主语从句
一、主语从句的定义和位置
在复合句中作主语的从句叫主语从句，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。
例句：
However, what concerned him most was that farmers often had poor harvests and sometimes even had a serious shortage of food to eat.
It doesn’t interest me whether you succeed or not.
主语从句的引导词
从属连词（不作成分） that, whether (不能用if)
连接代词（作成分） what(ever),who(ever),whom(ever) 作主语、宾语等
which 作主语、定语等
whose 作定语
连接副词（作状语） when, where, how, why 作状语
1.that和whether引导主语从句的区别：
that不作成分，无意义，不可省略；whether不作成分，有意义，译为“是否”。
That the earth is round is a fact.
Whether he will pass the exam is uncertain.
2.what和that引导主语从句的区别：
what引导主语从句时在从句中充当句子成分，如主语．宾语．表语，而that 则不然。

That she is still alive is a consolation.
三、主语从句的特殊用法
1. 当句子的主语是一个从句时，该句子的谓语用单数。
That he will pass the exam is certain.
Which book I shall choose hasn’t been decided.
what 引导的从句做主语时，谓语的单复数取决它的表语。
What I want is the book.
What I want are some books.
It作形式主语的结构：
It is ＋名词＋主语从句
It is a fact that the earth is round.
It is an honor that many specialists came to our English class.
(2) It is ＋形容词＋主语从句

It is strange that she came to school late this morning.
(3) It is ＋不及物动词＋主语从句

知识点02 表语从句
一、表语从句的定义和位置
在复合句中作表语的从句叫做表语从句。位于主句的系动词之后，对主语进行解释、说明，使主语的内容具体化。系动词包括状态类系动词（be动词，seem, appear, keep, remain, stay…）感官类系动词（look, smell, taste, sound, feel…）和变化类系动词（become, get, turn, grow, fall, come, go…）。
例句：
1. The question is whether we can make good preparation in such a short time.
2. But the fact remains that we are behind the other classes.
二、表语从句的引导词

连接代词（在从句中作主语、宾语、表语、定语） what, who, whom, whose, which, whatever, whoever, whichever …
连接副词（在从句中作状语） when, where, how, why
1.that引导表语从句：
that引导表语从句时, 在句中只起连接作用, 不充当句子成分, 无实际意义, 一般不能省略。

2.whether引导表语从句：
whether引导表语从句时，起连接作用，意为“是否，究竟，到底”，在句中不作任何成分。

2. because, why引导表语从句

3. 需使用虚拟语气的表语从句

【即时检测】

知识点03 宾语从句
一、宾语从句的定义和位置
在复合句中作宾语的从句叫做宾语从句，通常放在主句谓语动词（及物动词）、介词及某些形容词（afraid）之后。
例句：
She did not know what had happened.
Our success depends upon how well we can cooperate with one another.
I am afraid (that) I’ve made a mistake.

which 作主语、定语等
whose 作定语

if引导宾语从句
介词后的宾语从句不能用if引导。
It all depends on whether they will join us for a picnic. (不能用if引导)
that 引导宾语从句
引导宾语从句的that常可省略，但是当两个that从句由and或or连接时，第二个从句的that不能省略。
Mr. smith told the workers(that) John had worked very hard and that he wanted him stay.
三、宾语从句的特殊用法
1.宾语从句中的虚拟语气
表示“建议、命令、要求”等意义的动词，如suggest, demand, order, insist等，其后的宾语从句中谓语动词用should + 动词原形，should可省略。
She demanded that he（should）return the books he borrowed from her.
2.宾语从句的时态
如果主句的谓语是过去时，宾语从句的时态要用过去的相应时态。但若宾语从句表示的是客观真理或自然现象，其谓语仍用一般现在时。如：
The teacher told us that the earth moves round the sun.
3.it作形式宾语，宾语从句后置
当宾语从句后有宾语补足语时，通常用it作形式宾语，而将宾语从句后置。如：
Do you think it possible that the work will be finished by the end of this month
4.否定前移
当主句主语是第一人称，且谓语为think, believe, suppose, expect等动词时，如果宾语从句表示否定意思，通常否定前移，即否定主句谓语。如：
I don’t think (that) I can ever forgive him.
