2024高考英语-复合句写作之名词性从句

2024高考英语-复合句写作之名词性从句

复合句写作之—名词性从句一、概念释义在英语中,包含一个主谓结构的句子叫简单句。

如果一个句子包含两个或更多的主谓结构,这个句子就叫复合句。

比较下列两组句子:1、Your explanation (主语) sounds (系动词) reasonable (表语).【只有一个主谓结构,简单句!】What you said just now (主语从句) sounds (系动词) reasonable (表语).【宾语包含一个主谓结构,复合句!】2、I (主语) believe (谓语) your honesty (宾语).【只有一个主谓结构,简单句!】I (主语) believe (谓语) that you are honest (宾语从句).【宾语包含一个主谓结构,复合句!】主语从句What you said just now 中的What,宾从that you are honest 中的that 都是引导从句的关联词。

从句结构和简单句基本一样,只不过从句前多了连接词。

复合句分为名词性从句、定语从句(形容词性从句)和状语从句(副词性从句)。

其中,名从分为主从(Subject Clause)、宾从(Object Clause)、同从(Appositive Clause)、表从(Predicative Clause),简记为SOAP(肥皂)这些从句之所以被称为名词性从句,是因为这些从句在句子中扮演名词的角色。

注意:名从的语序均为陈述语序!二、关联词分类: 了解并正确使用关联词是写好名词性从句的关键,引导名词性★It作形式主语的实质:例:英语晚会将会在何处举行还没有宣布。

_____________________________________________________________________ STEP1: 在中文的概念中,发现应由一个句子充当主语;STEP2: 用It整体取代该句子,充当傀儡;并置于句首;STEP3:选择适当关联词,将充当主语的句子置于句末。

(完整版)高中英语语法总结-名词性从句

名词性从句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。

第一节知识点讲解顾名思义,主语从句在句子中作主语。

有时本身出现在主语的位置上,也有时出于句子结构的考虑退到句子的尾部,前面用形式主语 it 代替。

从句作主语时,谓语动词一般为单数形式。

如 :What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.Tips: 主语从句的 that 绝对不能省去。

因为句子是不能做主语的,故用 that 引导。

若去掉则没有了主语,而宾语从句的 that 可省。

主语从句: That he is right is known to all of us.宾语从句: We all know (that) he is right.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。

1、It depends on weather if she will come back on time .
2、I asked him if he could do me a favor .
If与whether的区别:
1、If不能引导放于句首的主语从句,而whether可以。 2、引导表语从句用whether,不用if。 3、引导同位语从句用whether,不用if。 4、whether可以引导从句作介词的宾语,不用if 。 5、whether or not 连在一起可以,但if不可以。而 “whether-----or not = if -----or not”
同位语从句:
定义:在复合句中充当同位语的句子。 同位语从句用来对其前面的抽象名词进行解释说明,被解释说明的词和 同位语在逻辑上是主表关系。 同位语常见名词:fact, suggestion, advice, idea, decision, news, thought, hope, belief, truth, doubt, promise, possibility, truth, warning, message, reason, report, question,explanation, wish, problem等。 常见的连接词:that, whether, what, who, how, when, where等。 用法: The thought that I want to buy my mother a birthday gift makes me excited.that 引导的同位语从句,解释说明 thought,从句不缺成 分 There is some doubt whether he will come. whether 引导同位语从句,if 不能引导同位语从句 we haven’t made the decision where we are going to spend our vacation. 有时同位语从句可以不紧跟解释说明的名词后面。 The news is surprising that he won the match.

语法重难点解析复合句的构成与用法

语法重难点解析复合句的构成与用法

语法重难点解析复合句的构成与用法复合句是由一个主句和一个或多个从句组成的句子。

而从句又可以分为名词性从句、定语从句和状语从句三种。

本文将对复合句的构成和用法进行详细解析。

一、名词性从句名词性从句可以在句子中充当主语、宾语、表语或同位语。

常见的名词性从句有主语从句、宾语从句和表语从句。

1. 主语从句主语从句在句子中充当主语,常由连接词that引导。

例如:- That he passed the exam is a great relief to his parents. (他通过考试让他的父母松了一口气。

)2. 宾语从句宾语从句在句子中充当宾语,常由连接词that或疑问词引导。

)二、定语从句定语从句用于修饰某个名词或代词,常由连接词that、which、who、whom或whose引导。

例如:- The book that I borrowed from the library is very interesting. (我从图书馆借的那本书非常有趣。

)定语从句可以是限制性或非限制性的。

限制性定语从句是对先行词进行必要的限定,如果去掉从句整个句子的意思就会有所改变;非限制性定语从句是对先行词进行额外的说明,如果去掉从句整个句子的意思仍然完整。

三、状语从句状语从句用于修饰主句或其中的某个成分,并表达时间、地点、条件、原因、目的、方式、让步等关系。

常见的状语从句有时间状语从句、地点状语从句、条件状语从句、原因状语从句、目的状语从句、方式状语从句和让步状语从句。

1. 时间状语从句时间状语从句用来表达动作发生的时间,常由连接词when、while、as、before、after等引导。

名词性从句就是在复合句中起相当于名词作用的从句

名词性从句就是在复合句中起相当于名词作用的从句

名词性从句就是在复合句中起相当于名词作用的从句,共包括四种类型:宾语从句、主语从句、表语从句和同位语从句。

引导名词性从句的连词有:that, if, whether等。

引导名词性从句的连接代词有:that,what, which, whom, whose, whatever, whoever,whichever等。

引导名词性从句的连接副词有:why, when, where, wherever, how以及how构成的短语how long, how often, how soon, how far, howmany/much等。

宾语从句宾语从句在复合句中可以作谓语动词(及物)的宾语,也可以作介词、某些形容词的宾语,还可以作非谓语的宾语。

一.及物动词后的宾语从句及物动词后的宾语从句可以由从属连词、连接代词和连接副词来引导。

1.由从属连词that引导由从属连词that引导的宾语从句有些就相当于陈述句的直接引语转化来的间接引语。

连词that在宾语从句中不充当成分,本身没有实际的意义,一般可以省略。

宾语从句中使用陈述句语序,时态与主句保持一致。

e.g. He told me (that) he had sold his old house.I think (that) eating too much is bad for people’s health.注意:引导宾语从句的that可省略,但以下几种情况下不能省略。

(1)当及物动词后有两个宾语从句时,第一个that可省略,第二个that不可省略;e.g. I believe (that) you have done your best and that you will pass theexam without difficulty.(2)当有形式宾语时,连接真正宾语的that不能省略;e.g. We thought it necessary that we tell her the truth.(3)当that从句与主句谓语动词之间有插入语或者从句主语有插入语时,that不可以省略。

英语中的复合句------名词性从句一,名词性从句综合讲解1、分类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。

2、引导词一览表词形词义在从句中所作的成分that-------- ---------If/whether 是否--------- Who(ever) (无论)谁(主格)主语,表语Whom(ever) (无论)谁(宾格)宾语Whose(ever) (无论)谁(所有格)定语What(ever) (无论)什么主语,宾语,表语Which(ever) (无论)哪个主语,宾语,表语when 什么时候状语where 在哪里状语how 怎样,怎么状语why 为什么状语(注:1、because,as,as if和as though也可以引导表语从句。

以后详讲。

)3、关于引导词1、引导名词性从句的连接词可分为三类:连词:that,whether,if (不充当从句的任何成分)连接代词:what, whatever, who, whoever, whom,whose, which.连接副词:when, where, how, why2、that引导名词性从句,本身无词义,也不作从句中任何成分。

名词性that-从句在句中能充当主语、宾语、表语、同位语和形容词宾语。

例如:主语:That he is still alive is sheer luck. 他还活着全靠运气。

宾语:John said that he was leaving for London on Wednesday. 约翰说他星期三要到伦敦去。

表语:The fact is that he has not been seen recently. 事实是近来谁也没有见过他。

同位语:The fact that he has not been seen recently disturbs everyone in his office.近来谁也没有见过他,这一事实令办公室所有的人不安。

形容词宾语:I am glad that you are satisfied with your job.你对工作满意我感到很高兴。

(注:由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。

宾语从句在复合句中作宾语。

引导宾语从句的连词that一般可省略。

例句:I hope (that) everything is all right.)(补注:不可省略连词(只有连词that才能谈省不省略的问题,因为连词不在从句中作任何成分,且三个连词中只有它没有意义,所以有时候它可以省略)的情况。

(1)介词后的连词(由于that一般不用于引导介词的宾语从句,引都不引导,又何谈省略之说呢?所以这个说法我有所怀疑)。

(if也不可引导介词的宾语从句。

引导介词的宾语从句只能由wh--型的词引导。

连词中只有whether能引导)(2)That引导主语从句、同位语从句时,一般不能省略。

引导宾语从句或表语从句时,可以省略。

That she was chosen made us very happy.We heard the news that our team had won.)(再补注:宾语从句中的连接词that有时可省有时又不可省,在以下几种情况中that 不能省略:(A)当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时,that不可省略;(B)当that 从句与另一名词性从句并列作宾语时,that不能省;(C)当that作介词宾语时,that不可省掉。

如:He judged that, because he was a child, he did not understand wineEveryone knew what happened and that she was worried.The reason lies in that she works harder than the others do.)3、名词性wh-从句由wh-词引导的名词从句叫做名词性wh-从句。

Wh-词包括who, whom,. whose, whoever, what, whatever, which, whichever等连接代词和where, when, how, why等连接副词。

Wh-从句的语法功能除了和that-从句一样外,还可充当介词宾语、宾语补语和间接宾语等。

例如:主语:How the book will sell depends on its author. 书销售如何取决于作者本人。

直接宾语:In one's own home one can do what one likes. 在自己家里可以随心所欲。

间接宾语:The club will give whoever wins a prize.俱乐部将给得胜者设奖。

表语:My question is who will take over president of the Foundation. 我的问题是谁将接任该基金会主席职位。

宾语补足语:She will name him whatever she wants to. 她高兴给他起什么名字就取什么名字。

同位语:I have no idea when he will return. 我不知道他什么时候回来。

形容词宾语:I'm not sure why she refused their invitation. 我尚不能肯定她为什么拒绝他们的邀请。

介词宾语:That depends on where we shall go.那取决于我们去哪儿。

4、连词whether和if有词义,表“是否”,在句中不担任任何成分,不能省略。

if, whether引导的名词从句分类:(1)yes-no型疑问从句从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同。

例如:主语:Whether the plan is feasible remains to be proved. 这一计划是否可行还有等证实。

宾语:Let us know whether / if you can finish the article before Friday. 请让我们知道你是否能在星期五以前把文章写完。

表语:The point is whether we should lend him the money. 问题在于我们是否应该借钱给他。

同位语:They are investigating the question whether the man is trustworthy. 他们调查他是否值得信赖。

形容词宾语:She's doubtful whether we shall be able to come. 她怀疑我们是否能够前来。

介词宾语:I worry about whether he can pass through the crisis of his illness. 我担心他是否能度过疾病的危险期。

(2)选择性疑问从句选择性疑问从句由关联词if/whether…or或whether…or not构成。

例如:Please tell me whether / if they are Swedish or Danish. 请告诉我他们是瑞典人还是丹麦人。

I don't care whether you like the plan or not.我不在乎你是否喜欢该计划(注:常用whether而不宜用if的六种情况。

whether与if 均为"是否"的意思。

但在下列情况下,whether 不能被if 取代:1. 引导主语从句并在句首2. 引导表语从句3. 该从句是作介词宾语4. 从句后有"or not"5、后接动词不定式时。

6、引导同位语从句例如:(1)Whether he will come is not clear.(2)Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。

(3)The question is whether she should have a low opinion of the test?(4)Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。

(5)I wonder whether he will come or not. 我想知道他来还是不来(6)It does not matter whether she will come or not.她来不来都没关系。

(7)Can you tell me whether to go or to stay? 你能否告诉我是去还是留?(8)I do not know whether to go.我不知道是否该去。

(9)the problem whether we will build another school has not been settled.我们是否再建一所学校的问题还没有定下来。

)4、注意事项1、what与that初学者易混淆。

选what还是that要根据关联词在从句中是否担任成分。

that和what的区别:that 引导名词性从句时,在主从句中不以当任何句子成分,也没有任何含义;而what引导名词性从句时,在主从句中都要充当一定主语、宾语、表语或定语,what的意思是:“什么, …的….”What surprised me most is her cheerful expression on her face.2、名词性从句很作小许变动,易于转化为定语从句。

比如说:(1)“what”引导的名词性从句如表示“所··事/人”和“什么”“什么样的”相当于定语从句中的“先行词+that/which”引导的定语从句。

(2)“whoever”等引导的名词性从句相当于定语从句中的“anyone+who”引导的定语从句。

3、名词性从句与定语从句相同点与区别相同点:名词性从句包括主语从句,宾语从句,同位语从句和表语从句四种。

其在句子中的作用相当于一个名词,分别作主语,宾语,同位语和表语。

名词性从句与定语从句,它们都是一个完整的句子,都可由that引导,且句子都用陈述语序。
