名词性从句-三大从句的语法讲解与练习

1、名词性从句第8页共12页定义：在句子中起名词作用的句子叫名词从句（Noun Clauses）.名词性从句包括主语，宾语，表语，同位语从句名词性从句中使用陈述句语序。/从属连词that; whether; if（只起引导从句的作用，在从句中不做句子成分）1.分类Y连接代词what, whatever, who, whoever, whom, whomever, whose, whic h,等.在从句 中做主语，宾语，表语，定语等句子成分。引导名词 性从句的 连接词.连接副词when, where, how, why, whenever, however, wherever 等在从句中做状语成分。

2、2.名词性从句的连接词选用原则：“缺什么就补什么（从句中缺宾语，指物）I know what he is talking about.Do you know who he is?（从句中缺表语，指人）It + be + -ed 分词 + that-从句It is universally acknowledged that./It is known thatIt + be +名词+ that-从句It is common knowledge/ a factthat 是常识/事实主语从句It +不及物动词+ that-分句It happens that 碰巧./It occurs tosb.tha

3、t 突然想起It作形式主语和it引导强调句的比较强调句 ： It is in the morning that the murder took place.（去掉该结构后，句子成分完整）主语从句 ：It was a pity that you shouldn ' t go to see the film.（从句中缺地点状语）Where he will go is unknown.I，m suthat they will come tomorrow.（从句中什么者B不缺 ）I don ' t knowhich book I should choose. （从句中缺定语 ）定义：充

4、当主语功能的句子叫 主语从句That she was chosen made a great stir 俵动）in her school.注意：it作形式主语的that-从句有以下四种不同的搭配关系:It + be +形容词+ that-从句It is necessary / important that .宾语从句（在句子中作主语成分）Wh whatever /whichever/ whoever 弓 I导主语从句的区另* 1JI Whatever是what的强调形式表示无论什么"相当于 anythingthat Whatever / Anything that she does

5、is wrong.n whoever是who的强调形式，表示 无论谁'相当于anyone everwho .Whoever / Anyone who walks around in such a heavy rain will catch a cold.；ni whichever无论哪个；无论哪些既指人，又指物.可修饰名词与 of连用Whichever book you borrow doesn，t mattto us.Whichever of us fulfills his task will lend a hand to others.(定义：在复合句中充当宾语功能的句子叫宾语从句

6、We can learn what we didn't know.We find it necessary that we (should) practice English every day.某些作表语的形容词，如sure, happy, glad, certain等之后可带宾语从句I am glad that you can come and help me.注意： wish/would rather后的宾语从句中要用虚拟语气。shou dI wish I had finished my homework yesterday.I ' d rath-ou had been

7、there yesterday在表示建议，命令，请求的词后面的宾语从句当中用可以省略should + V,His pale face suggested that he was ill so I suggested that he should go to see the doctor.He insisted that he was innocent and insisted that he should be set free.注意it作形式宾语的结构that 一般不接介词宾语，偶尔可作 except, in 的宾语；其它介词后面需用it作形式宾语He differs from his ro

8、ommates in that he devoted his spare time to reading.He knows nothing about Jim except that he is from London.You can depend on it that he will help you in time of emergency.r定义：充当表语功能的句子被叫做表语从句。IThe question is whether we can make good preparation in such a short表语从句time.i注意：reason后面的表语从句只能用that,不能

9、用why引导. The reason is that （because x）The reason why we didn 'trust him is that he has often lied.（该句型中why引导一个定语从句）定义：同位语从句跟在名词后面，进一步说明该名词的具体内容.这些名词主要是表示抽象概念的词如fact, news, promise, idea, truth; possibility;statement; warning; advice 等同位语的引导词有that; whether; why; who; where; how 等；其中 that和whether只

10、起引导作用其他连词具有实际意思，同时在同位语中作句子成分。同位语从句（The news that China broken the world record in the Olympic Games hascheered all of us.The question why so many people would choose to live in the countrysidebut to work in the city is still under discussion. （ why弓I导同位语从句解释说明中心语 question的内容；且 why在从句中作状语）I注意： 只起引导作用

11、时，连接词用that而不用whichWhere did you get the idea that she could not come. 同位语从句和定语从句的区别：就看that在作引导的从句中是否做句子成分The suggestion that he raised at the meeting is very important.（that引导定语）The suggestion that the students should have plenty of exercise is verygood. （that引导同位语从句）,在名词性从句当中只能用wh,在引导让步状语从句两者可以互换.H

12、e will believe whatever others say.1. No matter+wh与wh+ever区别（划线部分部分为名词性从句，不能互换）Whatever others say, he will believe it.（划线部分为状语从句，可以互换 ）Whoever walks around in such a heavy rain will catcha cold.（不可互换）原则：能用if的情况，都能用whether表“是否”1 在表进，同位语,主语（置于句首时）从句时只用whether表"是否"The question is whether the

13、 film is worth seeing.（表语从句）I have no idea whether we should go to the party.（同位语从句）Whether we shall attend the meeting hasn ' t beendecided yet.（主语从句 句首） It is doubtful whether / if he will come here.一些重要知识（主语从句，句末时可互换） 形容词；介词；discuss后的宾语从句中只用whether表"是否"It depends on whether you can

14、do the work well.2. Whether / if区别（介词兵语）T The students are discussing whether they will goout for a picnic this Sunday.JII am not sure whether he will come here or not.（形容词的宾语）W whether与 or或 or not 的搭配Do you mind whether a man or_woman does the job.I don't care whether or not he comes.名词性从句提升练习主
