篇一：名词性从句
一.概念
名词性从句共有四种:主语从句,表语从句,宾语从句和同位语从句
二.相关知识点精讲
1． 主语从句：主语从句在整个句子中作主语。
(1)不同于其它的连词，它不充当句子的成分，只是单纯的连接词，通常不可以省略。分句置于句首时，that绝对不可以省略。
That the driver could not control his war was obvious.
It was obvious that the driver could not control his car.
(2)if不能用在主语从句中，而是用whether
Whether he left (or not) is unknown
(3)当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。
What we need is more time and money.
What we need are many more books.
2.表语从句：表语从句出现在系动词后，充当表语。
The trouble is that we are short of money.
Go and get your coat. It’s where you left it.
(1) 引导表语从句除了上述三类词外还有because, as if/ as though等等
The reason (why/for which?..) is that ??
It/This/That is because??
(2) 连系动词“appear, look, seem”的两个常用句型
It seems/appears that?.
It looks/seems as if/as though??(与事实相符用陈述语气，与事实相反用虚拟语气)
(3) as也可以引导表语从句
Things are not always as they seem to be
3.宾语从句：及物动词，形容词和介词后加宾语从句作其宾语。
(1) 宾语从句时态与主句相呼应，但宾语从句表示的是客观真理或普遍现象除外 The teacher told us that the earth moves around the sun
(2) 连词whether和 if可以互换，但注意下列情况
连词后紧跟or not时用whether
I want to know whether or not they will come.
作介词宾语是用whether引导宾语从句
He was interested in whether he saw her there.
连接词后直接加不定式，不能用if只能用whether
He doesn’t know whether to stay or not.
如果宾语从句是否定时，一般用if引导
I care if he will not attend the meeting.
(3) 当宾语从句后带宾补时，要用“主语+谓语+it +宾补+that-clause,that不可省略 I think it certain that she will do well in her exam.
(4) 当主语是I, we，主句用think, believe, suppose, expect, imagine五个动词时，
用否定转移
I don’t think he will win the game, will he?
(5) that在宾语从句常可以省略，但由and或 but连接两个或多个宾语从句时，仅可以省
略第一个连词that
He said (that) he had eaten nothing but that he wasn’t hungry.
(6) 注意区别if引导的宾语从句和条件状语从句
I don’t know if he will come.
If he comes, I’ll let you know.
4.同位语从句，在句中作某些名词的同位语，对前面的名词进一步说明。用在下列名词 fact,news,idea,hope,believe,hope,thought,doubt.truth,order,suggestion, word etc.
(1) There is no doubt that he will come.
There is doubt whether he will come.
Word came that Napoleon would come to inspect them.
There is no possibility that?.
(2) that引导的同位语从句与定语从句的区别：
在同位语从句中：that不可以省略，不作成分;定语从句的关系代词that在定语从句作成分，作宾语时可以省略
We are interested in the news that some foreigners would visit our school. We are interested in the news that he told us.
when, where引导的同位语从句与定语从句的区别：
在定语从句中，when, where前有分别表示时间、地点的先行词；而在同位语从句中无此对应关系
They have no idea at all where he has gone.(同位语从句)
Go and get your coat. It’s in the place where you left it.(定语从句)
5.疑问词-ever既可以引导名词性从句，也可以引导让步状语从句，而no matter+疑问词只能引导让步状语从句
No matter where I go, my heart is towards China.
I believer whatever he says. Whatever he says, I will never believe him. who与 whoever的区别
who是“谁”的意思，表示具有疑问，who相当于anyone who“无论谁”
Whoever leaves the room last ought to turn off the lights.
Can you tell me who that gentleman is?
6．当名词性从句缺少主语、宾语或表语时，引导词通常用what，它相当于。另外，有时具有感叹意义all that, anything that或 the thing(s) that
What we can’t get seems better than what we have.
Tom thought what a beautiful girl Mary was.
7.注意区分it作形式主语的主语从句与强调句
强调句句型It is/was+被强调部分+that,去掉It is/was, that，句子仍然成立。 It is natural that they should have different views.主语从句
It is only lately that he had had a family himself.强调句
What was it that he wanted? I don’t know what it was that he wanted. It was in the hotel where he stayed that we discussed the serious problem
8.注意it作形式主语的主语从句和as引导非限制性定语从句引导的不同
It is known to all that the earth is round.
As is known to all. the earth is round.

篇三：名词性从句.名词性从句
疑问词引导的名词性从句导学案
在句子中起名词作用的从句叫名词性从句。名词性从句的功能相当于名词词组，在复合句中能担任主语，表语，宾语，同位语，介词宾语等，因此根据它在句中的句法功能，名词性从句又可以分为主语从句，表语从句，宾语从句和同位语从句。本单元主要介绍由疑问词引导的名词性从句。疑问词有两类，即疑问代词(what, whatever, which, whichever, who, whoever, whom, whomever, whose) 和疑问副词(when, where, how, why)。疑问代词通常在从句中作主语，表语和宾语。疑问副词则通常在从句中作状语（时间状语，地点状语，方式状语或原因状语）。请看如下例句，并试着分析作引导词的疑问词在从句中所担任的成分。
(作引导词的疑问代词在主语从句中作宾语) 作引导词的疑问代词在宾语从句中作宾语) (作引导词的疑问代词在同位语从句中作定语) (作引导词的疑问代词在表语从句中作宾语) Whoever leaves the room last ought to turn off the lights.
(作引导词的疑问代词在主语从句中作主语) (作引导词的疑问副词在主语从句中作时间状语) (作引导词的疑问副词在同位语从句中作原因状语) (作引导词的疑问副词在同位语从句中作方式状语)
运用名词性从句时的注意点：
1) 关于that的省略
一般情况下，宾语从句中的that是可以省略的。但在下列几种情况下，that一般不可省略。 ①介词后面的that不能省。
Peter is a good student except that he is sometimes careless.彼得是好学生，只是有时粗心。 ②并列连词and连接两个或两个以上宾语从句，第二个及以后的宾语从句中的that不省略。 My uncle says (that) he has served here for twenty years and that he is going to retire next month. 我叔叔说他在这儿工作已二十年了，下个月即将退休。
③主句谓语动词与that从句之间有插入语，that不可省略。
He said that, if he could manage it, he would come for dinner.
他说，如果他安排得好的话，他会来吃晚饭的。
④宾语从句中有其他从属连词时，that不能省略。
He told me that if it was necessary they would work all night.
他告诉我，如果需要的话，他们就干个通宵。
2) 名词性从句的词序
名词性从句在句中要用陈述句语序。如：
He asked me what was the matter with me.
We’ve heard the news that we’ll move into the new house.
Whatever you say will interest us all.
3) whether和if的用法
①whether和if在宾语从句中可以互换，但是作介词宾语时连接词一般用whether。如： It all depends on whether they will come back. 一切都取决于他们是否会来。
②后面直接跟or not 时用whether。如：
I didn’t know whether or not he had arrived in Wuhan. 我不知道他是否已经到达武汉了。 ③主语从句，表语从句中只能用whether。如：
Whether the meeting will be put off has not been decided yet.
会议是否会被推迟还没有被决定。
The question is whether they have so much money.
问题在于他们是否有很多钱。
④whether可以引导同位语从句，用以说明前面的名词的内容，if不能。如：
We ought to discuss carefully the question whether we can do it or not.
我们应当认真讨论是否能做此事这个问题。
⑤whether常与or连用表示一种选择，if不能这样用；whether也可与动词不定式连用但if不能。如：
The question of whether they are male or female is not important.
他们是男性还是女性不重要。
I have not decided whether to go or not. 我还没有决定是否要去。
4) 疑问代词 + ever和no matter + 疑问代词的区别。
①疑问代词 + ever可引导名词性从句，在从句中要充当一定的部分。如： 在主语从句中作主语)
任何违反规定的人必须受罚。
Y在宾语从句中作宾语)
你可以在商店中选择你喜欢的任何东西。
②疑问词 + ever还可引导让步状语从句。如：
Whoever breaks the rule, he must be punished. 无论谁违反规定，都必须受罚。
Whatever you do, you must do it well. 不管你做什么，你必须把它做好。
③no matter + 疑问词只能引导让步状语从句。如：
No matter what you do, you must do it well. 不管你做什么，你必须把它做好。
No matter who breaks the rule, he must be punished. 无论谁违反规定，都必须受罚。
5) 名词性从句中主句和从句的时态一致
①宾语从句中主句和从句的时态保持一致，但如果从句中表示的是客观现象，虽然主句是过去时态，从句仍用一般现在时。如：
Hello, I didn’t know you were in London. How long have you been here?
喂，我不知道你在伦敦。你在这里多久了？
The teacher told us that light travels at a very high speed.
老师告诉我们光以非常快的速度传播。
②主语从句作主语相当于单数第三人称作主语，谓语动词用单数，如果由and 连接两个或两个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，
谓语动词用单数。如：
When the meeting will begin has not been decided yet.
会议何时开始还没有决定。
When they will start and where they go have not been decided yet.
他们何时出发以及去何处还没有决定。
When and where the meeting will begin has not been decided.
会议何时何地开始还没有决定。
6)含有宾语从句复合句的反意疑问句
①反意疑问句一般与主句一致。
He said they were going to help me, didn't he？ 他说过他们要帮我，不是吗？
She told you that the mat was her own work, didn't she?
她告诉过你这个垫子是她亲自做的，是吗？
②当主句的主语为第一人称，谓语动词是think, believe, consider, imagine, suppose, hope 等词时，反意疑问句应与宾语从句保持一致。这时特别要注意否定转移的问题。
I suppose you're serious, aren't you? 我想你是当真的，不是吗？(不可用don't I)
I don't suppose he's serious, is he? 我想他不是当真的，是吗？ (不可用do I)
提示：
如果主语是第二、第三人称，则疑问句部分与主句一致，且不存在否定转移的问题。 You don't think we can speak English, do you? 你认为我们不会说英语，对吗？
He thinks he's got the right answer, doesn't he? 他认为自己找到了正确的答案，是吗？
7) because, why引导的表语从句
That's because he didn't understand me. 那是因为他没有理解我。（That's because … 强调原因） That's why he got angry with me. 那正是他对我生气的原因。（That's why…
