引导名词性从句的关联词在传统的语法中,有连接代词、连接副词和关系代词、关系副词之分;连接代词、连接副词引导名词性从句和关系代词、关系副词引导定语从句。
本书根据最新资料不再作此分类,通称关系代词和关系副词。
引导名词性从句的关联词大致相同,它们分别是:连词:that, whether, if;关系代词:who, what, which , whom, whose, whatever, whoever, whomever, whichever;关系副词:when, where, how, why,however, whenever, wherever。
引导从句时一般不用逗号和主句分开。
详细见下表:类别词义在从句中的作用that 无任何词义仅起连接作用,在从句中不充当任何句子成分if和whether 意为“是否”,表明从句意义的不确定性起连接作用,在从句中不充当任何句子成分关系代词who, what, which,whom, whose, whatever, whoever, whomever, whichever 有各自自身的意义起连接作用,并在从句中充当主、表、宾、定语等关系副词when,where,why,how, however, whenever, wherever 有各自自身的意义起连接作用,并在从句中充当状语1、that从句与wh-关系代词和关系副词引导名词性从句的区别连词that在从句中不作成分,不含疑问意义;而wh-连词在从句中作成分,且含有疑问意义;或what/where从句相当于一个名词后加一个定语从句。
It worried her a bit that her hair was turning grey. 她的头发在变白令她有点担忧。
(that在从句中只起引导词作用,不作成分)What caused the accident is still a complete mystery. 事故发生的原因仍然是个不解之谜。
名词性从句之连词篇在复合句中起名词作用的从句叫名词性从句。
根据其在句中的不同语法功能,名词性从句可分为主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的有:连词that, whether, if, because;连接代词what, whatever, who, whoever, whom, whose, which和连接副词when, where, how, why等。
高考对名词性从句的考查主要体现在连接词的选择上,我们一起来看下面几组连接词的用法区别。
1. if与whether:在引导宾语从句时,两者常可互换;但在引导主语从句、表语从句和同位语从句时只能用whether。
如:1) I wonder whether the sports meeting will be held as planned next week.(whether引导的宾语从句,可用if代替。
)2) Whether the sports meeting will be held as planned next week depends on the weather. (whether引导的是主语从句,不能用if代替。
)2. whether, if与that:在引导名词性从句时,whether和if含有疑问、不确定的意义,而that 表示肯定、确定的含义。
如:1) There is still doubt whether the experiment will be a success.(doubt用于肯定句时,后接whether引导的同位语从句。
)2) There is no doubt that the experiment will be a great success.(doubt用于否定句时,后接that引导的同位语从句。
)3. that与what:that是连词,在名词性从句中只起连接作用,不作任何成分;what是连接代词,在从句中可作主语、宾语、表语等。
名词性从句与连接词的关系及例句整理名词性从句是指在句子中充当名词的从句。
它可以在句子中担任主语、宾语、表语、同位语等成分。
而连接词是将名词性从句与主句连接起来的词语,起到引导和连接的作用。
名词性从句与连接词之间的关系密切,正确使用连接词可以更好地构建句子。
一、名词性从句的引导词及作用1. 从属连词"that"和"whether/if"从属连词"that"引导的从句多用作宾语,可以代替较正式的"whether/if"。
比如:- I don't know that he will come to the party.- I don't know whether/if he will come to the party.2. 连接代词"what", "where", "when", "which"和"who"连接代词本身在名词性从句中充当主语、宾语、表语或同位语。
比如:- What she said surprised me. (作宾语)- Where he lives is a mystery. (作主语)- This is the place where we met. (作表语)- The question is which is better. (作同位语)- I'm not sure who will win the game. (作宾语)3. 连接副词"how", "why"和"whether/if"连接副词一般引导名词性从句作表语或宾语。
比如:- The question is how we can solve the problem. (作表语)- He asked me why I was late. (作宾语)- I'm not sure whether/if it will rain tomorrow. (作表语)二、名词性从句的例句整理1. 主语从句主语从句在句子中充当主语,常由连接代词"what", "where", "when", "which", "whether/if"等引导。
名词性从句连接词
引导名词性从句的连接词可分为三类:
1、连接词:that, whether, if (不充当从句的任何成分)
2、连接代词:what, whatever, who, whoever, whom,whose, which
3、连接副词:when, where, how, why
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.
比较: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、whether引导主语从句并在句首。
2、引导表语从句。
3、whether从句作介词宾语。
4、从句后有"or not" 。
Whether he will come is not clear.
大部分连接词引导的主语从句都可以置于句末,用it充当形式主语。
It is not important who will go.
It is still unknown which team will win the match.。
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。
例如:What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。
引导名词性从句的连接词可分为三类:连接词: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, why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。
例如:That she was chosen made us very happy.?她被选上了,我们很高兴。
We heard the news that our team had won.我们听到消息说我们队赢了。
比较: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.whether引导主语从句并在句首2. 引导表语从句3. whether从句作介词宾语4. 从句后有"or not"关系代词有:who, whom, whose, that, which等。
关系副词有:when, where, why等。
关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词,并在句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主语时,从句谓语动词的人称和数要和先行词保持一致。
1)who, whom, that这些词代替的先行词是人的名词或代词,在从句中所起作用如下:Is he the man who/that wants to see you?他就是你想见的人吗?(who/that在从句中作主语)He is the man whom/ that I saw yesterday.他就是我昨天见的那个人。
(whom/that在从句中作宾语)2) Whose 用来指人或物,(只用作定语, 若指物,它还可以同of which互换), 例如:They rushed over to help the man whose car had broken down. 那人车坏了,大家都跑过去帮忙。
带领名词汇性从句的连交词汇可分为三类:之阳早格格创做连词汇:that(无所有词汇意)whether,if(均表示“是可”标明从句真质的没有决定性)as if ,as though(均表示“佳像”,“好像”)以上正在从句中均没有充当所有身分连交代词汇:what, whatever, who, whoever, whom,whose, whichever,whomever连交副词汇:when, where, how, why,how many,how much,how often没有成简略的连词汇:1. 介词汇后的连词汇2. 带领主语从句战共位语从句的连词汇没有成简略.主语从句(正在复合句中,做句子的从句喊主语从句.带领主语从句的词汇有从属连词汇that,whether以及连交代词汇who,what,which,whoever,whatever,whichever呵连交副词汇when,where,why,how等.)it做形式主语的从句1. It is +adj./n.+从句比圆:It is a pity/shame that…遗憾的是…2. It +vi.+从句比圆:It seems that…好像…It happened that…碰巧…3.

英语语法名词性从句用法小结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、同位语等,因此根据它在句中不同的语法功能,名词性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. 名词性从句的连接词引导名词性从句的连接词可分为四类:1. that(无含义,不充当成分)2. whether, if(有“是否”的含义,但不充当成分)3. 连接代词:what, whatever, who, whoever, whom, whomever,whose, which,whichever.(在从句中做主语、宾语、表语和定语)连接副词:when, whenever,where,wherever, how, however,why(在从句中做状语)4. as if,as though,because(不充当成分,在名词性从句中只引导表语从句)二. 四类名词性从句语法要点1.主语从句在整个句子中用作主语的从句叫主语从句。
What he wants to tell us is not clear.他要跟我们说什么,还不清楚。
It is known to us how he became a writer.我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced.英语晚会将在哪里举行,还没有宣布。
it 作形式主语:有时为避免句子头重脚轻,常用形式主语it 代替主语从句作形式主语放于句首,而把主语从句置于句末。
It is clear that he is innocent in the accident.很明显,他在这场事故中是无辜的。
2. 宾语从句在整个句子中用作宾语的从句叫宾语从句。

名词性从句一、名词性从句的连接词引导名词性从句的连接词有三类:连接词、连接代词和连接副词。
1. 连接词有:that(本身无意义),whether/if (是否)。
连接词只起到连接作用,在从句中不作任何成分。
2. 连接代词:who,whom,whose,which,what,whatever,whoever等。
它们不但起到连接作用,还在句中充当主语、宾语、定语、表语等成分。
3. 连接副词:when(= the time when),where(=the place where),how(=the way/that in which), why (=the reason why ), 它们不但起到连接作用,还在从句中作状语。
注意:what与that引导名词性从句的区别1. what在名词性从句中可充当主语、宾语、表语,意义相当于the thing(s) that, 引导主语从句时,其谓语动词的单复数依句意而定。
①What the lecturer said is very valuable.②We wonder what he will do next.2. that 引导名词性从句不作任何成分,无意义。
引导主语从句时,常用it作形式主语,谓语动词用单数,引导宾语从句时,that常被省略。
①That he will refuse the offer seems unlikely.②We have found (that) all the tickets have been sold out.③It is a pity that you missed such a fine talk.二、主语从句的基本用法1. that引导的主语从句既可放在句首,也可放在句尾,that只起到连接作用,无词义,在从句中不作成分,一般不能省略。

语法突破技巧名词性从句的连接词与用法名词性从句是从句用作主语、宾语、表语或同位语的句子。
在英语语法中,连接词是将名词性从句与主句连接起来的关键。
一、连接词的种类1. 引导主语从句的连接词:(1)that:用于陈述句,作为主语从句的引导词。
例如:"That he is late is not surprising."(2)whether/if:用于陈述句或者是一般疑问句,作为主语从句的引导词。
例如:"Whether/If he is late is not surprising."2. 引导宾语从句的连接词:(1)that:用于陈述性宾语从句,例如:"I know that he is late."(2)whether/if:用于是否疑问宾语从句,例如:"I don't know whether/if he will come."(3)连接代词who, whom, whose, which, what:作为主语从句来引导名词性从句,例如:"I don't know who/whom is responsible for this mess."3. 引导表语从句的连接词:(1)that:用于陈述性表语从句,例如:"My belief is that he is late."(2)连接代词who, whom, whose, which, what:作为表语从句的引导词,例如:"My concern is who/whom is responsible for this mess."4. 引导同位语从句的连接词:(1)that:用于同位语从句,例如:"The fact that he is late is not surprising."(2)连接代词who, whom, whose, which, what:作为同位语从句的引导词,例如:"His claim that he is late is not credible."二、使用技巧1. that的使用:(1)作为引导词时,可以省略在主语从句和表语从句中,例如:"What surprises me is (that) he is late."(2)如果主句的动词是感觉动词(feel, believe, think, etc.)时,可使用that引导名词性从句。
一、引导名词性从句的连接词分类引导名词性从句的连接词可分为三类:连词(5个):that(无意义,不可省,不充当任何成分)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”)以上在从句中均不充当任何成分连接代词(9个):what, whatever, who, whoever, whom, whomever, whose, which, whichever 连接副词(7个):when, where, how, why, whenever, wherever, however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.比较whether与if 均为"是否"的意思。
但在下列情况下,只可用whether:1. whether引导主语从句并在句首2. 引导表语从句3. whether从句作介词宾语4. 从句后有"or not"5. 引导同位语从句Whether he will come is not clear.大部分连接词引导的主语从句都可以置于句末,用 it充当形式主语。
It is not important who will go.It is still unknown which team will win the match.二. 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。
例如:What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。
有时为避免句子头重脚轻,常用形式主语it代替主语从句作形式主语放于句首,而把主语从句置于句末。
主语从句后的谓语动词一般用单数形式。
常用句型如下:(1) It + be + 名词 + that从句(2)It + be + 形容词 + that从句(3)It + be + 动词的过去分词 + that从句(4)It + 不及物动词 + that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有:It is necessary (important, natural, strange, etc.) that …It is suggested (requested, proposed, desired, etc.) that…三、宾语从句名词从句用作宾语的从句叫宾语从句。
引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。
1. 由连接词that引导的宾语从句由连接词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。
例如:He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好,别人什么都不好。
注意:在demand、order、suggest、decide、insist, desire, request, command, doubt等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。
例如:I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2. 用who,whom, which, whose, what, when, where, why, how, whoever, whatever, whichever 等关联词引导的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。
例如:I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whoever needs help a warm support. 凡需要帮助的人,她都会给予热情的支持。
3. 用whether或if引导的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。
此外,whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether,不用if:a. 引导主语从句并在句首时;b. 引导表语从句时;c . 引导从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。
例如: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。
The question is whether she should have a low opinion of the test?现在的问题是她是否应该有一个低意见的测试?Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
I wonder whether he will come or not. 我想知道他来还是不来。
Can you tell me whether to go or to stay? 你能否告诉我是去还是留?4. 注意宾语从句中的时态呼应,当主句动词是现在时,从句根据自身的句子情况,而使用不同时态。
例如:I know (that) he studies English every day. (从句用一般现在时)I know (that) he studied English last term. (从句用一般过去时)I know (that) he will study English next year. (从句用一般将来时)I know (that) he has studied English since 1998. (从句用现在完成时)当主句动词是过去时态(could, would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用现在时态。
例如:The teacher told us that Tom had left us for America.5. think, believe, imagine, suppose等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。
即将从句中的否定形式移到主句中。
例如:We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
四、表语从句在句中作表语的从句叫表语从句。
引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if引导。
其基本结构为:主语 + 系动词 + that从句。
例如:The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That’s just what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的,当主语是reason时,表语从句要用that引导而不是because。
例如:The reason why he was late was that he missed the train by one minute this morning .【注意】whether 可引导表语从句,但与之同义的if却通常不用于引导表语从句。
五、同位语从句同位语从句说明其前面的名词的具体内容。
同位语从句通常由that引导,可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
例如:The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别:that作为关系代词,可以引导定语从句,充当句子成分,在从句中作宾语时可以省略; that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
试比较下面两个例句:I had no idea that you were here.(that引导同位语从句,不能省略)Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句,作宾语,可以省略)六、名词性that-从句(1)由从属连词that引导的从句叫做名词性that-从句。
