上海中考英语语法考点: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。在复合句中能作主语、

宾语、表语、同位语、介词宾语等。形容词性从句即定语从句;副词性从句即状

语从句;名词性从句包括主语从句,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

1,从属连词五个:that无词义,在从句中不做成分,在宾语从句中可省略。

whether,if 有词义,在从句中不做成分,不可以省略。as if, as though不做成分。

2,连接代词九个:what, whatever, who, whoever, whom, whomever, whose, which, whichever,有词义,在从句中做成分,不可以省略。

3,连接副词七个:when, where, how, why, whenever, wherever, however有词义,

在从句中做状语,不可以省略。

二. 主语从句

1,主语从句:通常由下列词引导:从属连词that,whether ;连接代词what,

who,which,whatever,whoever,whom;连接副词how,when,where,why

等。It is known to us how he became a writer.

2,常用it作形式主语放于句首,而把主语从句置于句末。谓语动词一般用单数

形式。It is a fact that,It is an honor that,It is common,It is a pity that,It is said that,

t seems that, It is natural that

3,what 与that 在引导主语从句时的区别

what 引导主语从句时在从句中充当句子成分,如主语.宾语.表语,而that 则

不然。What you said yesterday is right. That she is still alive is a consolation.

三、宾语从句

1.由连接词that引导的宾语从句,that在句中不担任任何成分,常被省去。

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,句子语序要用陈述语序。

用whether或if引导的宾语从句,保持陈述语序。

3,think, believe, imagine, suppose,guess, expect, fancy, consider等动词引起的否

定性宾语从句中,要否定前移。doubt whether, don’t doubt that…

四、表语从句

1、在复合句中,位于系动词之后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。

It

It appears/seems that… It happens that… 

It is because … 

the reason is that … 

It seems as if…

turns out that… 

It looks as if… 

2、当主语是reason时,表语从句要用that引导而不是because。whether 可引

导表语从句,但if不可以。

五、同位语从句

1、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,that

不可以省略, 可由whether引导,不可用if.

2、同位语从句的先行词是一些有限的抽象性名词,如belief, advice, demand,

doubt, possibility, thought, proposal, case, fact, hope, idea, information, message,

news, order, problem, promise, request, suggestion, wish, word, reason, question,

truth, conclusion, result.等。而定语从句的先行词可以是任何物和人。

3、同位语从句与定语从句的区别

1)定语从句是形容词性的,与先行词之间存在所属关系,起修饰限定的作用。

同位语从句是名词性的,与先行词是同位或等同的关系, 起补充说明的作用。

2)定语从句中的that既代替先行词,同时在从句中作主语或宾语,而同位语从

句中的that是连词,不充当句中任何成分。

The news that he told me is that Tom would go abroad next year. 定从

The news that Tom would go abroad is told by him. 同从,that不可省略。

3)What不能引导定语从句,但可以引导同位语从句。

I didn’t have the idea what you mean.

4)How, when, where, why的先行词与从句意义相关时,它们是关系副词,引导

定从。不相关时,这些词是连接副词,引导同位语从句。

Do you have any idea where he lives.

He solved the problem why the TV was out of order.

There is some doubt whether he will come.

以上都是同位语从句。whether, how不可引导定从。

The reason why he was late is that he was ill. 定从

六、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:

主语:How the book will sell depends on its author.

直接宾语:In one's own home one can do what one likes.

间接宾语:The club will give whoever wins a prize.

表语:My question is who will take over president of the Foundation.

宾语补足语:She will name him whatever she wants to.

同位语:I have no idea when he will return.

形容词宾语:I'm not sure why she refused their invitation.

介词宾语:That depends on where we shall go.

七、what 引导的名词性从句

1,表示“……的东西或事情”,相当于“the thing that...; all that...; everything that....:He saves what he earns. What Mary is is the secretary. 玛丽的职务是秘书。

的人或的样子”,相当于the person that

2,表示“……

He is no longer what he was. Who is it that has made Fred what he is now?

相当于the amount/number that

3,表示“……

的数量或数目”,

Our income is now double what it was ten years ago.

的时间”, 相当于the time that:

4,表示“……

After what seemed like hours he came out with a bitter smile.

的地方”, 相当于the place that

5,表示“……

This is what they call Salt Lake City.

八、whether与if 在作是否的意思时

1,可用if的情形:宾语从句一般可用if或whether引导。

2,只用whether的情形

1)宾语从句中,在decide, discuss后,有or not时,作介词宾语时,if会引起歧

义时,从句放句首时必须用whether。

2)引导主语从句、表语从句、同位语从句及接不定式时。

Could you tell me if you know the answer ?

Whether there is life on the moon is an interesting question.

Everything depends on whether we have enough money.

初中英语语法——三大从句汇总(重点笔记)

初中英语语法——三大从句汇总 在英语中,主要有三大从句,即名词性从句(包括主语从句,宾语从句,表语从句,同位语从句)、形容词性从句(即定语从句)、副词性从句(即 状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等)。以 下是一些基本的从句的语法知识点 A、定语从句专项讲解与训练 一、定语从句概念 定语从句(attributive clause),顾名思义,就是一个句子作定语从属 于主句。定语一般是由形容词充当,所以定语从句又称作形容词从句。另外, 定语从句是由关系代词或关系副词引导的,故又称作关系从句。 定语从句一般放在它所修饰的名词或代词之后,这种名词或代词被称作先 行词。请看示例: The woman who lives next door is a teacher. 先行词定语从句 在所有的从句中,算定语从句最难掌握,因为汉语里没有定语从句,汉语 里只有定语,而且总是放在名词之前来修饰名词。 二、关系代词引导的定语从句 关系代词代替前面的先行词,并且在定语从句中充当句子成分,可以作主语、宾语、定语等。常见的关系代词有:who, that, which。它们的主格、宾格和所有格如下表所示: 先行词主格宾格所有格 人 who whom whose 物 which which whose of which 人、物 that that — (一)关系代词who, whom和 whose的用法 who代替人,是主格,在定语从句中作主语。例如: An architect is a person who designs buildings. 建筑师是设计房屋的人。 I will never forget the teacher who taught us chemistry in the first

必备英语中考英语名词性从句练习题(含答案) 一、初中英语名词性从句 1.We believe ________ you have been devoted to ________ naturally of great necessity. A. that; being B. all that; be C. that all; are D. what; is 【答案】 D 【解析】【分析】句意:我们相信你所投入的当然是非常必要的。分析句子可知,believe 后接宾语从句,宾语从句中you have been devoted to缺少宾语,表示事物故用what;what you have been devoted to为主语,从句作主语,谓语动词用单数,故选D。 【点评】考查名词性从句和主谓一致,本题涉及what引导的主语从句和一般现在时。 2.Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。 【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。 3.--- made her ashamed of herself? --- the lowest mark in her class. A. What; Because she got B. Was it what; Getting C. What was it that; That she got D. What was it that; Get 【答案】 C 【解析】【分析】句意:——是什么让她对她自己感到羞愧?——是她获得了她班上的最低分让她惭愧。A中的what是句子的主语,但是because引导的从句不作主语,是原因状语从句,故排除;B的第一空是错误形式,故排除;C、D两项的第一个选项是一样的,说明第一个题干是一个强调句型,特殊疑问句下的强调句型,有what引导;第二个空是对what的回答,因为what是上一句的主语,That she got the lowest mark in her class是从句,可以作主语;而D项的get是动词原形,不能作主语,故答案为C。 【点评】考查强调句型的使用和对特殊疑问句的回答,注意问什么回答什么,也就是说疑问词what是句子的主语,回答的内容也需要在句子中能作主语。 4.________ has been proved is that animals and insects have their own languages. A. What B. As C. It D. That 【答案】 A 【解析】【分析】句意:已被证明的是动物和昆虫有自己的语言。根据is判断,此处为主

A. That; what B. That; that C. What; that D. What; what 【答案】 A 【解析】【分析】句意:众说周知,礼貌在每一个国家中都是非常重要的,但是麻烦是,不同的国家对于什么是良好的礼貌有着不同的认识。逗号前有两个谓语动词,一个是are,一个是is known,故是两句话,需填连词连接这两句话,根据句意可知,前面是主语从句,故填that,此处的that,只起连接作用不作任何成分。about是介词,其后是个句子故应填连词把这两句话连接起来,所缺词作are的表语,故填what。因此选A。 【点评】考查名词性从句,本题涉及that引导的主语从句和what引导的宾语从句。 2.While some behaviors may seem strange to you, remember you consider normal probably seems just as unusual to others. A. it; that B. what; that C. that; what D. which; that 【答案】 C 【解析】【分析】句意:虽然有些行为对你来说可能很奇怪,但请记住,你认为正常的行为对别人来说可能也不寻常。第一空为宾语从句,从句结构完整用that起连接作用,第二空为主语从句,从句中consider缺少宾语,应该用what,故选C。 【点评】考查名词性从句,本题涉及that引导的宾语从句和what引导的主语从句。 3.It has been pointed out ________ plays a vital role in driving away one's anxiety is one's sweet childhood memories. A. what that B. which C. that D. that what 【答案】 D 【解析】【分析】句意:有人指出,驱除焦虑所起着至关重要的作用是童年美好的回忆。本句时一个主语从句,it作形式主语,真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.,主语从句中又有一个主语从句,且此主语从句中缺少主语,所以用what引导。故选D。 【点评】考查名词性从句,本题涉及what引导的主语从句。 4.________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties. A. As; whose B. It; whose C. As; whom D.

初中英语语法名词性从句

名词性从句 在句子中起名词作用的句子叫名词从句。名词从句的功能相当于名词词组,名词从句又可分为主语从句、宾语从句、表语从句和同位语从句。 一.主语从句 1.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。主语从句要求使用陈述句语序。 What surprised me most was that the little girl could play the violin so well. How he was successful is still a puzzle. That he is going aboard made him excited. Where the English party will be held has not yet been announced. 注: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。 It is interesting that you like him. It is a pity that you can not go to the party tonight. 2.连接词的选用 (1)that和what的选用 that和what都可引导主语从句。what除起连接作用外,还在名词性从句中充当某些成分,可作从句的主语、宾语或表语。而that在名词性从句中不充当任何成分,无词义,只起连接词作用。 What he wants is a book. 他想要的是一本书。 That light travels in straight lines is known to all. 众所周知,光线沿直线运行。 (2)if和whether的选用

初中英语名词性从句专题训练答案及解析

初中英语名词性从句专题训练答案及解析 一、初中英语名词性从句 1.We believe ________ you have been devoted to ________ naturally of great necessity. A. that; being B. all that; be C. that all; are D. what; is 【答案】 D 【解析】【分析】句意:我们相信你所投入的当然是非常必要的。分析句子可知,believe 后接宾语从句,宾语从句中you have been devoted to缺少宾语,表示事物故用what;what you have been devoted to为主语,从句作主语,谓语动词用单数,故选D。 【点评】考查名词性从句和主谓一致,本题涉及what引导的主语从句和一般现在时。 2.While some behaviors may seem strange to you, remember you consider normal probably seems just as unusual to others. A. it; that B. what; that C. that; what D. which; that 【答案】 C 【解析】【分析】句意:虽然有些行为对你来说可能很奇怪,但请记住,你认为正常的行为对别人来说可能也不寻常。第一空为宾语从句,从句结构完整用that起连接作用,第二空为主语从句,从句中consider缺少宾语,应该用what,故选C。 【点评】考查名词性从句,本题涉及that引导的宾语从句和what引导的主语从句。 3.________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties. A. As; whose B. It; whose C. As; whom D. It; whom 【答案】 D 【解析】【分析】句意:我们都知道,那位老科学家,过去生活很艰苦,到了八十多岁还在努力工作。第一空it is known to us all that…是个固定句型,意为“众所周知…”;第二空为介词+关系代词引导的定语从句,先行词the old scientist指人,作介词for的宾语,只能用whom,故选D。 【点评】考查名词性从句和定语从句,本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。 4.Some people believe _______ has happened before or is happening now will repeat itself in the future. A. whatever B. whenever C. wherever D. no matter what 【答案】 A 【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。 【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。
