名词性从句
名词性从句
?定义：在复合句中起名词作用的从句叫名词从句(Noun Clauses）。?功能：相当于名词词组, 它在复合句中能担任主语、宾语、（动词宾语或介词宾语）、表语、同位语等，因此根据它在句中不同的语法功能，名词从句又可分别称为
主语从句——subject clause
宾语从句——object clause
表语从句——predicative clause
同位语从句—— appositive clause
找出名词性从句并判断是什么名词性从句
1.At lunch time, the radio weatherman reported that the mist would become a thick fog in the afternoon.
2.The question is whether the sports meet will be held as planned.
3.What he said is not right.
4.The fact that Polly didn’t ask for the man’s name is a pity.
引导名词性从句的连接词
陈述句(statement ) —— that
2.一般疑问句（yes/no question）—— whether/ if (是否)
3. 特殊疑问句（wh- question）——
who,whom ,whose，which,
whoever, whatever,whichever,
when, where, how,why,
whenever, wherever,however,
what （什么，所……的东西—指物）
当名词性从句中，既缺关联词又缺主语或既缺关联词又缺宾语或既缺关联词又缺表语时，用what.
名词性从句的语序：关联词+主谓
名词性从句的构成：
a. that + 主谓（陈述句）
That light travels in straight lines is known to all.
b. whether/if+主谓
I don’t know whether he will come or not.
c. wh- +主谓
This is what we are looking for.
疑问词引导的名词性从句要求使用陈述句语序，不能用一般疑问句语序。
他是怎么成功的仍然是个谜。
1.How was he successful is still a puzzle. ( )
2.How he was successful is still a puzzle. ( )
你能告诉我他住在什么地方吗？
1.Could you tell me where he lives? ( )
2.Could you tell me where does he live? ( )
高考名词性从句考点分析
主语从句考点一
1.为避免主语冗长,句子头重脚轻,经常用it作形式主语,主语从句放在后面作真正的主语.
1.It is certain that he will succeed.
2.It is not known whether he will go there.
3.It has not been decided yet when they’ll start the project.
在下列句型中常用that引导主语从句
▲It’s likely/possible/important/necessary/clear that…很可能/重要的是…/必要的是…/很清楚…
▲It’s said/ reported that…据说/据报道…
▲It seems/appears/happens that…显然、明显、碰巧..
▲It’s been announced/declared that…已经通知/宣布…
▲It’s no wonder that…并不奇怪/无疑…
▲It’s a pity/a fact /a common knowledge (众所周知）/ a common saying（俗话说）that…
考点二：使用主语从句应注意
1) 从句作主语，谓语常用单数，但以what开始的主语从句，如后面的表语为复数时，谓语也用复数。
?eg.What he wants to buy are three books and two ball pens.
?What he wanted to see was an end to all the armies of the world.
?2) that从句位于句首时，that绝对不能省略。
?That we are invited to the concert is good news to us.
考点三.It 作形式主语和引导强调句的比较。
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引导的强调句则是强调句子某一部分，无论强调的是什么成分，都可用连词that。被强调部分指人时也可用who。
?eg. a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。
?b) It doesn’t interest me whether you succeed or not.我对你成功与否不感兴趣。
?c) It is in the morning that the murder took place.谋杀案是在早上发生的。
?d) It is John that broke the window. 是John打碎的窗户。
宾语从句考点一：
1.Whether和if都可以引导宾语从句
（1）当whether后紧跟or/or not时,不用if.
▲I don’t know whether I will stay or not
（2）介词后面的宾语从句不能用if.
▲I worry about whether I hurt her feeling.
（3）whether to do 做动词宾语不能用if to do.
▲I’ not sure whether to go abroad.
（4）if 不用于主语从句、表语从句和同位语从句中
▲Whether to held the sports meeting has not been decided yet.
if/whether
1. I asked her __________ she had a bike.
2.______ we will hold a party in the open air
tomorrow depends on the weather.
3. We’re worried about ________ he is safe.
4. I don’t know ___________ he is well or not.
5. I don’t know ________ or not he is well.
6. The question is _________ he should do it.
7.The doctor can hardly answer the question______ the old man will recover soon.
8. I don’t know _______ to go.
9. It is not certain____________ he will succeed.
在主语从句中，只有用it作形式主语时，whether, if都能引导主语从句，而if引导的主语从句只能放在句尾，否则也只能用whether。
Whether we shall attend the meeting hasn’t been decided.
宾语从句考点二: that 在宾语从句中的省略和保留
在主+谓+it(形式宾语)+宾补+that从句(真正宾语) 的句型中不省略
▲We must make it clear that we mean what we say.
由连词and连接的两个由that引导宾语从句中,第二个或以上that
不省略.
▲He told me（that）he would come and that he would
在主语从句、表语从句和同位语从句中不可省略
▲The truth is that throughout history few
ancient monuments have avoided damage altogether.
that 可省略的情况：
1.单个宾语从句中的that可省略
2.并列的宾语从句中的第一个从句的引导词that 可省略
that（that）
1.I don’t think ________ she is coming.
2.It is a pity ________ he has made such a mistake.
3.The reason is _________ he is careless .
4.The news ________ our team won the match inspired us.
5.I don’t think it necessary _________ you should read English
aloud.
6.He told me __________ his father had died and __________ he
had to make a living alone.
考点三：在带有宾补的句子里，通常用it的形式宾语，而将宾语从句置于宾补之后。
1. He found it strange that no one else had arrived.
2. I don’t like it when you shout at me.
3. I want to make it clear whether she still loves him or not.
宾语从句考点四：宾语从句的时态呼应
1. 如果主句时态是现在时或将来时,从句谓语
可根据句意需要而选用任一种时态.
a .他相信他的梦想总有一天会实现的.
He believes _________________________ .
(his dream will come true some day.)
b .请告诉我你昨天这个时候在干什么.
Please tell me______________________________________ (what you were doing at this time yesterday.)
2. 如果主句谓语是过去时,从句谓语动词一般用过去的
某种时态,但从句表达的是客观事实、真理、自然规
律等时，从句谓语通常用一般现在时。
①他告诉我他正在为考试做准备。
He told me ________________________________ .
(he was preparing for the examination)
②他说他已离开家乡十年了。
He told me _________________________________.
(he had been away from his hometown for ten years)
③老师告诉我们光是沿直线运行的。
The teacher told us _________________________.
(light travels in a straight line.)
表语从句考点一
?if 不引导表语从句，表语从句还可用as/as though/as if 来引导。
①The question is whether we can rely on him.
②Things were not as they seemed.
③He looked as if he was going to cry .
表语从句:在句中充当表语成分，一般放在连系动词之后.
作用：对主语进行解释说明。
表语从句考点二
1.The reason ______ we didn't trust him was ______ he often lied．
2.The reason ____ he gave for his absence was ______ he was ill.
reason 后面的表语从句只能用that 引导, 不能用why 引导, 但reason后面的定语从句可以用why 或者that 引导。
同位语从句考点一
同位语从句的格式：n+连接词+从句
（1）There is no doubt that he’s fit for the job.
（2）The question whether it is worth doing will be raised at the meeting.
同位语从句考点二
同位语从句在句中充当同位语成分，其一般跟在一些抽象名词对名词作进一步解释说明.
能接同位语从句的名词有：
advice, fact, demand, belief, doubt, hope, idea, information, message, news, order, problem, promise, question, request, suggestion, truth, wish, word等。
同位语从句考点三：
连接词通常是that,也可根据含义选用whether, what, when, where 等来引导同位语从句。
（1）I have no idea how he got the prize.
（2）They raised the question where I would take my holiday.
1.Two thirds of all girls in Britain are on a diet./ The fact worries their parents and teachers a lot.
The fact that two thirds of all girls are on a diet worries their parents and teachers a lot.
2.The Queen of England was on a three-day visit in China./ We heard the news last night.
We heard the news last night that the Queen of England was on a three-day visit in China.
名词性从句其余考点归纳：
名词性从句连接词的选用
（1）that 和what 的选用
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，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。
that/what
1.______ he wants is a book.
2. ______ he wants to go there is obvious.
3.The result is ______ we won the game.
4.This is _____ we want to know.
5.Is _____ he told us true ?
6.We should pay attention to ______ the teacher is saying.
7. I have no doubt _____ he will come.
8. I have no idea _____ he did that afternoon.
（2）其它连接代词和副词的选用
主要根据名词性从句中的具体意义,正确的选择who、which、when、where、why、how 等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。
我们何时举行运动会还没有决定。
a. ________ we shall hold our sports meeting is
not decided.
我不知道昨天谁打破了玻璃。
b. I don’t know _________ broke the glass
yesterday.
我不知道他长的什么样子。
c. I have no idea _________ he looks like.
这就是我忘记眼镜的地方。
d. This is _________ I left my glasses.
（3）who/whoever, what/whatever等的用法区别
一般说来，what/who等含特指意义，而whatever/whoever等含泛指意义，意为“无论什么/无论谁”。
eg. 1.It is generally considered unwise to give a child whatever he or she wants.
(这里的whatever表泛指意义) 无论孩子要什么就给他/她什么是不明智的
2.I can’t remember at the moment who
has said the words. (这里的who表特定的某人)
that/whether/where/how
1. I have no idea _________ he comes from.
2. He can’t answ er the question ________ he got the money.
3.He gave us many suggestions ________ we should get up earlier and take more exercise.
4.I have no doubt ________ he will win.
5. I have some doubt ________ he will win.
（4）下列动词或其名词形式后的名词性从句的谓语结构要用虚拟语气,结构为should + do, should 可省略
名词:一坚持：insist
二命令: command, order
三建议: suggest, propose, advise, recommend
四要求:demand, require, request, desire
①He gave me a suggestion that I ( should ) be calm now.
②He suggested that I (should) be calm now.
③It is suggested that I (should )be calm now.
④The suggestion was that I (should )be calm now.
同位语从句和定语从句的区别
1.定语从句是先行词的修饰语，它不涉及先行词的具体内容。定语从句中that不但起连接作用，而且在定语从句中充当一个句子成分，充当从句的宾语成分时可省略。
2.同位语从句对中心词的内容作进一步的解释和说明，表明中心词的具体内容。引导同位语从句的that 在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.
判断是定语从句还是同位语从句
(1).We expressed the hope that they had expressed.
(2). We expressed the hope that they would come to China again.
(3)The information has been announced that more middle school graduates will be admitted into university.
(4)The information that he revealed at the meeting is of great value.

名词性从句
名词性从句 在句子中起名词作用的各种从句，统称为名词性从句。根据它们在句中所起的语法作用，这类从句分别称为主语从句、 1.作动词的宾语 ①大部分宾语从句直接跟在动词后： He doesn’t know where the post office is. 他不知道邮局在哪里。 ②有些宾语从句前要有间接宾语： He told me what I should read. 他已告诉我应该读些什么。 ③如果宾语从句后面有宾语补足语，要使用形式宾语it，而将从句放到补足语后面： I thought it strange that he failed to call me. ④在think, believe, suppose, expect等动词之后的宾语从句中，如果从句谓语是否定含义，则不用否定形式，而将主句谓 语动词think等变为否定形式： I don’t think you are right. *⑤在think, believe, imagine, suppose, guess, hope 等动词以及I’m afraid等后，可用so代替一个肯定的宾语从句，还可用not代替一个否定的宾语从句： E.g. --- Do you believe it will clear up? 你以为天气会转晴吗？ --- I believe so. 我认为会这样。 (--- I don’t believe so./I believe not.) 我认为不会这样。 －Do you think it’s going to rain over the weekend? －. A．I don’t believe B．I don’t believe it C．I believe not so D．I believe not －Don’t you think Jack’s health has been ruined by over drinking? －Yes, he told me himself. A．the thing B．it C．so D．the fact 2. 作介词的宾语 ①that引导的宾语从句只有在except, in, but, besides等少数介词后偶尔可能用到： Your article is all right except that it is too long. 你的文章挺好，只是太长了。 Did she say anything about how we should do the work? 关于这工作我们该怎么做她说什么没有？ *②有时在介词和其宾语从句的中间加形式宾语it; 如短语动词answer for（担保）、count on (期待)、depend on、insist on、see to(负责，确保)等后接that引导的宾语从句时，必须冠以形式宾语it。 I’ll see to it that everything is ready. 我将负责把一切准备好。 ③介词后的宾语从句不能由if引导，而要用whether. I’m counting on it that you will come.我期待着你的到来。 She’ll see to it that he goes ahead.她将确保他继续进行。 3. 作形容词的宾语 在某些形容词（如afra id“恐怕”，sure“确信”，certain“肯定”，confident“相信”等）作表语时，可接一个that引导的宾语从句（也有人认为是状语从句）： I’m afraid (that) I have made a mistake.恐怕我犯了一个错误。 表语从句 表语从句放在连系动词（如be, seem, remain等）后： The question is whether we should accept their invitation. 问题是我们是否应该接受他们的邀请。 1.when, where, why, because, how 等引导的从句作This is 和That is 的表语 时，表示具体的时间、地点、原因、方式等： This is why we put off the meeting. 这就是我们推迟会议的原因。 This is why…＝＞This is the reason why… This is where…＝＞This is the place where… This is when…＝＞This is the time when… This is how…＝＞Thi s is the way(that/in which)… 2．主语是reason时，表语从句常用that, 不用because; The reason for his absence was that he was ill。 他缺席的原因是病了。 3．as, as if, because 有时也可引导表语从句； Things were not as they seemed to be. 情况并不是看上去的那个样子。 It looks as if it is (或：were) going to rain.看起来天要下雨。 ▲注意：as if引导的表语从句有时也可用虚拟语气，表示可能性小。 主语从句 主语从句在复合句中作句子的主语。引导主语从句的词有连词that, whether, 连接代词who, what which; 连接副词when, where, how, why等。 如：1) What is needed for the space trip is careful preparation. 2) Whether wild life can be well protected is of great importance. 3) Who will go makes no difference. 1.主语从句可以直接放在句首；也可用it作形式主语，而将从句放在句末。 如：That light travels in straight lines in known to all. It’s known to all that light travels in straight lines. 众所周知，光沿直线运行。 When we shall have our sports meet is still a question.
英语名词性从句知识归纳
名词性从句知识归纳 名词性从句是指在句子中相当于名词的从句，主要包括主语从句、宾语从句、表语从句和同位语从句。名词性从句不是修饰性从句，而是复合句中的主干。 e.g. That the boy failed again in the exam disappointed his mother. （主语从句） I know that he is writing his composition in his room. （宾语从句） The question is how we can finish it on time. （表语从句） The fact that some Chinese are still poor is really a great problem. （同位语从句） 一、宾语从句---及物动词、介词、部分形容词（certain, sure, glad, afraid, frightened, happy, pleased, sad, sorry, surprised, upset, satisfied等）后 e.g. I believe (that) he is honest. (that不充当从句内的任何成分，一般情况可省略) I’m glad that you are satisfied with your job. (that不充当从句内的任何成分) He doesn’t care if/whether it isn’t a fine day. (if/whether不充当从句内的任何成分) Please tell me what you want.

名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。因此，我们把主语从句、表语从句、同位语从句和宾语从句这四种从句统称为名词性从句。 主语从句(subject clauses)在复合句中起主语作用的从句叫主语从句。引导主语从句的词有从属连词、、关系代词、连接副词等。引导主语从句的关联词有从属连词that、whether，关系代词：who, what, which, whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever等。 That you don’t like him is none of my business.你不喜欢她不管我的事。 What he said is true. 他说的是真的。 Do you remember how he arrived almost at the end of the party?你记得他几乎是在宴会快结束时才到的吗？ This party's really where it's at, man! 啊，这个晚会真棒！Tell us how you fulfilled the heavy task ahead of schedule.告诉我们,你们是怎样提前完成这一艰巨任务的。 We have reason to believe that the fighting on the border may develop into a full-blown war. (喻)我们有理由相信边境上的冲突可能发展成一场全面战争。 He said that he would come. 他说他要来。
