Step 2:名词性从句基本知识梳理
一、主语从句、宾语从句和表语从句的定义及特点
(一)主语从句
主语从句是指在句中作主语的从句，位置与陈述句的主语相同。
Whether the sprts meet will be held is nt certain nw.运动会是否将举行现在不能确定。
[名师点津] 若主语部分结构较长，可以使用形式主语it，把真正的主语从句放于后面。
That she will d well in her exam is certain.
＝It is certain that she will d well in her exam.她在考试中会做得好，这是确定无疑的。
Hw we understand things has a lt t d with what we feel.
我们如何理解事物与我们的感觉有很大关系。
That he had met a kind librarian in the city library gave us n surprise.
他在市图书馆遇到了一位善良的图书管理员，这并没有使我们感到惊讶。
Every year, whever makes the mst beautiful kite will win a prize in the Kite Festival.
每年制作出最漂亮风筝的人都会在风筝节上获奖。
What he had said surprised everyne present.他所说的话让在场每一个人吃惊。
It seemed that he had dnated all his mney t thse in need.他似乎已将所有的钱都捐给了那些需要帮助的人。
(二)宾语从句
Everyne knws that the earth is made up f matter.每个人都知道地球是由物质构成的。
She asked me whether I had returned the bks t the library, and I admitted that I hadn't.
她问我是否把书还给图书馆了，我承认没有。
I dn't knw where I can place my luggage．我不知道我的行李可以放在哪里。
We discussed whether we shuld use the mney t buy a new huse.
我们讨论该不该用这笔钱买套新房子。
I'm nt certain whether the train will arrive n time.我不确定火车是否将会按时到达。
注意：形容词后跟宾语从句的用法只限于少数动态形容词，如sure(确信)，certain(肯定)，afraid(担心)，cnfident(有把握的)等。
注意
(1)宾语从句的否定转移：think、believe、suppse、 imagine等动词后的宾语从句中的否定词要转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I dn't think we need t waste much time n it.
我想我们不必在这上面浪费太多时间。(形式上否定主句，实际上还是否定从句)
(2)“dubt＋宾语从句”的应用。
肯定句中用whether或if，否定句和疑问句中用that。
I dubt whether he can pass the exam.我怀疑他是否能够通过此次考试。
I dn't dubt that he can pass the exam.我不怀疑他能通过此次考试。
D yu dubt that he can pass the exam?你怀疑他能通过此次考试吗？
(三)表语从句
1．表语从句在复合句中作表语，出现在连系动词之后，一般结构为“主语＋连系动词＋表语从句”。
2．表语从句实际上是对主语进行补充说明，从句表达的是主语的内容。
The fact is that he didn't ntice the car until t late.
事实是他注意到汽车时已经太晚了。
3．主句的主语是名词idea、advice、suggestin、rder、request、requirement等时，表语从句应用虚拟语气，即谓语动词用“(shuld＋)动词原形”。
My suggestin is that we (shuld) have a discussin abut this matter instead f setting it aside.
我的建议是我们应当讨论一下这个问题，而不是把它放在一边。
The mst pleasant thing f the rainy seasn is that ne can be entirely free frm dust.
雨季最令人愉快的事情是可以完全摆脱灰尘。
This is because abut seventy­ne percent f its surface is cvered by water.
这是因为它的表面有71%被水覆盖着。
名词性从句连接词
(一)that、whether和if
1．连接词that
that引导从句时，本身无意义，在从句中不充当成分。但是that在引导主语从句、表语从句时，一般不能省略。例如：
That he suddenly fell ill made us surprised.他突然生病让我们震惊。
The fact is that we are behind ther grups.事实是我们落后于其他小组。
在引导宾语从句时，常被省略；但是以下两种情况除外：
(1)多个并列从句出现时，第一个that可以省略，其他的不能省略。
She said (that) she wuld cme here and that I shuld wait fr her till Mnday.
她说她将会来这儿并让我等到星期一。
(2)含有形式主语it时，放于后面的宾语从句不能省略that。
They made it clear t the public that they did an imprtant and necessary jb.
他们向公众表明：他们所做的工作重要且必不可少。
2．连接词whether和if
(1)连接词whether/if在从句中意为“是否”，不充当成分，一般不能省略。
(2)在主语从句中位于句首时只能用whether；当用it作形式主语时，whether与if都可以。
Whether he passed the exam was nt certain.
＝It was nt certain whether/if he passed the exam.
不确定他是否通过了考试。
(3)表语从句中常用whether。
The questin is whether we shuld ask them fr help.问题是我们是否应该向他们寻求帮助。
(4)宾语从句中连接词whether和if常常可以互换。
I wnder whether/if he'll agree with me.我想知道他是否会同意我。
[点津] 宾语从句中用whether不用if的三种情况：
(1)与r nt连用
We dn't knw whether Tm will turn up at the meeting r nt.我们不知道汤姆是否会参加会议。
(2)位于介词之后
Everything depends n whether yu are fr it.每件事情都取决于你是否赞成它。
(3)位于动词不定式之前
I dn't knw whether t believe him.我不知道是否该相信他。
(二)连接代词what、 which、wh、whm和whse
连接代词what、which、wh、whm和whse在从句中的意义分别为“所……”“哪一个”“谁”“谁”“谁的”；在从句中起代词的作用，可作主语、表语、宾语或定语。
That's what we have said.(作宾语)那就是我们所说的话。
D yu knw which f the bys was late? (作主语)你知道哪个男孩迟到了吗？
Wh will cme t give the talk is knwn t us all.(作主语)我们都知道谁将来做报告。
The prblem is whm the headmaster will send t deal with it.(作宾语)问题是校长将要派谁来处理这件事情。
D yu knw whse T­shirt it is？(作定语)你知道这是谁的T恤衫吗？
[点津] 连接代词what、 which的区别：
which引导主语从句时需要限定一个有限的、较小的范围，而what指在一个较广的范围内进行选择或者根本没有范围。
Which f the bys brke the windw is already knwn.
已经知道是哪个男孩打破了窗户。
I dn't knw what bks the children can read.我不知道孩子们能读什么书。
(三)连接副词when、where、why和hw
when意为“何时”，在从句中作时间状语；where意为“哪里”，在从句中作地点状语；hw意为“如何”，在从句中作方式状语；why意为“为什么”，在从句中作原因状语。
When we'll set ff fr hme hasn't been decided yet.我们何时动身回家还没有被决定。
That was where I spent my hliday.那就是我度假的地方。
Nbdy knew hw she gt the prize.没有人知道她是如何获奖的。
This is why we put ff the meeting.这就是我们推迟会议的原因。
(四)复合连接词whatever、whichever、whever和whmever
连接代词whatever、whichever、whever和whmever在从句中的意义分别为“无论什么” “无论哪一个” “无论谁” “无论谁”；在从句中起代词的作用，可作主语、宾语或定语。
Whatever I have is at yur service.我所有的一切都供你使用。
I'll take whichever picture yu dn't want.我随便拿一幅你不要的画好了。
Whever breaks the law shuld be punished.无论谁违反了法律都应该受到惩罚。
Whmever yu invite will be welcme.你邀请的任何人都将受欢迎。
[名师点津] (1)whatever、whichever、wh(m)ever既可引导名词性从句，又可引导让步状语从句；n matter what、n matter which、n matter wh(m)只引导让步状语从句。
Whichever/N matter which dictinary yu want t buy, I'll pay fr it.无论你想买哪本词典，我都愿意付款。
(2)wherever (＝n matter where); whenever (＝n matter when); hwever (＝n matter hw)一般引导让步状语从句。
Hwever/N matter hw tugh the prblem may be, I'll wrk it ut by myself.
无论问题可能有多难，我都会自己解决它。
