名词性从句知识点总结在句子中起名词作用的句子叫名词性从句(Noun Clauses)。
名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,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、宾语从句、表语从句和同位语从句。
一.主语从句主语从句是在复合句中充当主语的从句,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。
1. It 作形式主语和it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引导的强调句则是对句子某一部分进行强调,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/whom。
例如: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。

名词性从句在句子中起名词作用的句子叫名词从句(Noun Clauses)。
名词从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,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、宾语从句、表语从句和同位语从句。
一、引导名词性从句的连接词引导名词性从句的连接词可分为三类:从属连词:that(无任何词意);whether, if(均表示“是否”表明从句内容的不确定性);as if ,as though(均表示“好像”,“似乎”)because。
以上在从句中均不充当任何成分连接代词:what, whatever, who, whoever, whom, whose, which. Whichever, whomever连接副词:when, where, how, why,whenever,whereever.名词性从句的分类1.主语从句作句子主语的从句叫主语从句。
主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。
that 在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。

名词性从句知识点
名词性从句知识点在英语语法中,名词性从句是一个重要且复杂的部分。
它在句子中起着名词的作用,包括主语从句、宾语从句、表语从句和同位语从句。
接下来,让我们逐一深入了解。
一、主语从句主语从句即在句子中充当主语的从句。
例如,“What he said is true”(他说的是真的。
)在这个句子中,“What he said”就是主语从句。
引导主语从句的连接词主要有三类:1、从属连词:that、whetherThat he will come is certain (他会来是肯定的。
)这里的“that”在从句中不充当成分,只起引导作用。
Whether she will go there is not decided (她是否会去那里还没决定。
)“whether”表示“是否”。
2、连接代词:what、who、which、whose、whatever、whichever、whoever 等What you need is more practice (你需要的是更多的练习。
)“what”在从句中充当宾语。
3、连接副词:when、where、why、how 等When the meeting will be held has not been announced (会议何时举行还未宣布。
)需要注意的是,主语从句后置时,常用 it 作形式主语,而将真正的主语从句放在后面。
例如:It is unknown whether he will come (他是否会来还不知道。
)二、宾语从句宾语从句在句中充当宾语。
比如,“I know that he is a student”(我知道他是个学生。
)“that he is a student”就是宾语从句。
引导宾语从句的连接词与主语从句类似:1、从属连词:that(在口语或非正式文体中常省略)、whether、ifHe said (that) he was busyI wonder if/whether he will come2、连接代词:what、who、which、whose、whatever、whichever、whoever 等She asked me what I was doing3、连接副词:when、where、why、how 等Could you tell me how I can get there?宾语从句的时态要根据主句的时态来变化。
名词性从句知识点
复合句中具有名词性质并且可以做主语、表语、同位语或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。
高考热点1)怎样判断名词性从句的类别;2)连词that 和what的用法与选择3)if 与whether的区别4)同位语从句与定语从句的区别5)名词性从句必须采用的陈述语序6)it 可充当形式主语和形式宾语7)疑问词+-ever的连词和不加-ever的连词在语义上的用法和差别核心解读一1、在名词性从句中,从句都用陈述语序。
2、引导名词性从句的词叫引导词。
引导词可以分为以下几类:1)从属连词that(用于表示肯定的含义), whether, if (表示疑问),这三个词只起连接作用,不充当从句中的任何成分,除宾语从句外(that可省),这些词均不可省略。
2)连接代词有who, whom, whose, what, which, whoever, whatever, whichever等。
这些词在从句中既起连接作用,又充当从句中的成分,如主语、宾语、表语、补语,且不可省略。
3)连接副词有when, where, why, how, wherever, however等。
它们既起连词作用,本身又做从句中的状语。
3、名词性从句中的时态一致问题1)在宾语从句中,当主句是一般现在时、将来时或现在完成时,起从句的谓语根据需要用适当的时态。
当主句是一般过去时,从句用过去的某个时态,但若宾语从句表示客观真理,格言,谚语等,从句的时态仍用一般现在时。
Have you told him that when we are to leave?Teacher told us that China lies in the west of Japan.Although she was listening, she didn’t hear what he was saying because t here was so much noise.2)在主语从句、表语从句或同位语从句中,应注意主语从句中的谓语动词的时态一致性及动作发生的先后关系。

The earth goes around the sun.=That the earth goes around the sun is a fact.B.一般疑问句转化为主语从句,只能用whether来引导,不能用if。
一般疑问句语序转化为陈述语序。
Will it rain tomorrow?=Whether it will rain tomorrow is not know.C.特殊疑问句变为主语从句,还是用原来的疑问词引导(特殊疑问句有两种结构,一种是疑问词+一般疑问句;另一种是特殊疑问句本身就是陈述结构)What does she want?=What she wants is a trip to Lijing.她想要的是去丽江旅行。
名词性从句知识点总结(word文档物超所值)
名词性从句名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。
因此,名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。
(一)引导名词性从句的连接词1、连接代词:who, whose, whom, what, which。
有词义,在从句中担任成分,如主语、表语、宾语、或定语等。
2、连接副词:when, where, why, how。
有词义,在从句中担任成分,作状语。
3、连接词:that, whether, if, as if。
that 无词义,在从句中不担任成分,有时可省略;if (whether), as if虽有词义,但在从句中不担任成分。
注意:1、连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。
连接代词与连接副词在从句充当句子成分,连接词whether 和if(是否),as if(好象)在从句中不充当句子成分,只起连接作用。
根据句义,如果连接代词与连接副词,whether、if 和as if都用不上时,才用that作连接词(that本身无任何含义)。
2、不可省略的连词:(1)介词后的连词(2)引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.We heard the news that our team had won.(二)主语从句1、主语从句在复合句作主语。
e.g. Who will go is not important.2、用it作形式主语,主语从句放在句末。
e.g. It doesn’t matter so much whether you will come or not.主要句型有:(1)It+be+形容词+that从句。
It is probable that he told her everything. 很可能他把一切都告诉她了。
(2)It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。

名词性从句知识点总结在句子中起名词作用的句子叫名词性从句(Noun Clauses)。
名词性从句的功能相当于名词词组, 它在复合句中能担任主语、宾语、表语、同位语、介词宾语等,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、宾语从句、表语从句和同位语从句。
一.主语从句主语从句是在复合句中充当主语的从句,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。
1. It 作形式主语和it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引导的强调句则是对句子某一部分进行强调,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/whom。
例如: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。
(强调句型)d) It is John that broke the window.是John打碎的窗户。
(强调句型)2. 用it 作形式主语的结构(1) It is +名词+从句It is a fact that …事实是…It is an honor that …非常荣幸It is common knowledge that …是常识(2) It is +形容词+从句It is natural that…很自然…It is strange that…奇怪的是…(3) It is +不及物动词+从句It seems that…似乎…It happened that…碰巧…It appears that…似乎…(4) It +过去分词+从句It is reported that…据报道…It has been proved that…已证实…It is said that…据说…3. 主语从句不可位于句首的五种情况:(1)if 引导的主语从句不可居于复合句句首。
(2)It is said /reported…结构中的主语从句不可提前。
例如:正确表达:It is said that President Jiang will visit our school next week.错误表达:That President Jiang will visit our school next week is said.(3)It happens/occurs…结构中的主语从句不可提前。
例如:正确表达:It occurred to him that he failed in the examination.错误表达:That he failed in the examination occurred to him.(4)It doesn’t matter how/whether …结构中的主语从句不可提前。
例如:正确表达:It doesn’t matter whether he is wrong or not.错误表达:Whether he is wrong or not doesn’t matter.(5)含主语从句的复合句是疑问句时,主语从句不可提前。
例如:正确表达:Is it likely that it will rain in the evening?错误表达:Is that will rain in the evening likely?4. what 与that 在引导主语从句时的区别what 引导主语从句时在句时在从句中充当句子成分,如主语.宾语.表语,而that 则不然。
例如:a) What you said yesterday is right.b) That she is still alive is a consolation二.宾语从句宾语从句就是在复合句中作宾语的名词性从句,通常放在主句谓语动词(及物动词) 或介词之后。
1. 作动词的宾语(1) 由that引导的宾语从句(that 通常可以省略), 例如:I heard that be joined the army. 我听说他参军了。
(2) 由what, whether (if) 引导的宾语从句,例如:a) She did not know what had happened.她不知道发生了什么。
b) I wonder whether you can change this note for me.我想知道你是否能帮我改一下笔记。
(3) 动词+间接宾语+宾语从句。
例如:She told me that she would accept my invitation.她对我说她会接受我的邀请。
2. 作介词的宾语,例如:Our success depends upon how well we can cooperate with one another.我们的成功取决于我们之间的合作。
3. 作形容词的宾语,例如:I am afraid (that) I’ve made a mistake.我恐怕我已经犯了一个错误。
注意:that 引导的从句常跟在下列形容词后作宾语:anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。
也可以将此类词后的that 从句的看作原因状语从句。
4. it 可以作为形式宾语it 不仅可以作为形式主语,还可以作为形式宾语而真正的宾语that 从句则放在句尾,特别是在带复合宾语的句子中。
例如:We heard it that she would get married next month. 我听说她下个朋就会结婚了。
5. 后边不能直接跟that 从句的动词这类动词有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。
这类词后可以用不定式或动名词作宾语,但不可以用that引导的宾语从句。
如:正确表达:I admire their winning the match.错误表达:I admire that they won the match.6. 不可用that从句作直接宾语的动词有些动词不可用于“动词+间接宾语+that从句“结构中,常见的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。
例如:正确表达:He impressed the manager as an honest man.错误表达:He impressed the manager that he was an honest man.7. 否定的转移若主句谓语动词为think, consider, suppose, believe, expect, fancy, guess, imagine等,其后的宾语从句若含有否定意义,一般要把否定词转移到主句谓语上,从句谓语用肯定式。
例如:I don’t think this dress fits you well. 我认为这件衣服不适合你穿。
三. 表语从句表语从句在复合句中作表语的名词性从句,放在系动词之后,一般结构是“主语+连系动词+表语从句”。
可以接表语从句的连系动词有be, look, remain, seem等。
引导表语从句的that常可省略。
另外,常用的还有the reason is that…和It is because 等结构。
例如:1) The question is whether we can make good preparation in such a short time.2) This is why we can’t get the support of the people.3) But the fact remains that we are behind the other classes.4) The reason he is late for school is that he missed the early bus.四. 同位语从句同位语从句就是在复合句中作名词的同位语的名词性从句。
1. 同位语从句的功能同位语从句对于名词进一步解释,说明名词的具体内容,一般由that引导,例如:1) The king’s decision that the prisoner would be set free surprised all the people.2) The order that all the soldiers should stay still is given by the general.2. 同位语在句子中的位置同位语从句有时可以不紧跟在它所说明的名词后面,而是被别的词隔开。
例如:He got the news from Mary that the sports meeting was put off.3. 同位语从句与定语从句的区别(1) 定语从句中的that既代替先行词,同时以在从句中作某个成分(主语或宾语),而同位语从句中的that是连词,只起连接主句与从句的作用,不充当句中任何成分。
(2) 定语从句是形容词性的,其功能是修饰先行词,对先行词加以限定,描述定的性质或特征;同位语从句是名词性的,其功能是对名词进行补充说明。
例如:1) The news that he told me is that Tom would go abroad next year.(他告诉我的消息是汤姆明年将出国。
)(第一个that引导的从句是定语从句,that在从句中作宾语)2)The news that Tom would go abroad is told by him.(汤姆将出国的消息是他讲的。
)(同位语从句,that在句中不作任何成分)高一英语名词性从句专项练习1.____he does has nothing to do with me.A. whateverB. No matter whatC. ThatD. If2.
