最新高三英语语法复习---名词性从句上课讲义
高三英语语法复习---名词性从句一、概说名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句的连接词的选用依据“从句缺什么成分补什么成分”的原则。
解题时，应首先确定选用连接代词还是连接副词。
然后再根据题意选用具体的连接词。
如果名词性从句中缺少主语、宾语、表语或定语，则选用连接代词。
如果从句中缺少状语，则选用连接副词。
如果从句中不缺成分，而仅表示陈述事实，则用that引导。
如果含有“是否”意义，则选用whether或if。
二、名词性从句的一般引导词1.连接词that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。
如：I hope (that) you enjoy your holiday. 希望你假期过得好。
That he likes you is very obvious. 很显然他喜欢你。
2.连接词whether 也不充当句子成分，但有自己的意思，表示“是否”；引导宾语从句时，可换成if，但引导其他名词性从句时不能换成if。
He asked whether [if] I would show him the way. 他问我是否可以给他带路。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。
(引导主语从句，不能用if 代替whether)3.连接代词who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。
如：That’s why she wanted to leave. 这就是她想离开的原因。
When we arrive doesn't matter. 什么时候到没有关系。
Tell me which one you like best. 告诉我你最喜欢哪一个。
4.连接副词when, where, why, how 等，也各自有自己的意义，在从句中作状语。

名词性从句讲解在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、宾语从句、表语从句和同位语从句。
名词性从句是中学阶段的一个重要语法项目，在历年的高考中几乎都涉及到，并且每年的命题各有变化。
分析历届高考试题名词性从句考查的焦点主要有以下六个方面1. 考查名词性从句的语序问题2. 考查引导词that与what的区别3. 考查it在名词性从句中作形式主语或形式宾语的用法4. 考查whether与if的区别5. 考查名词性从句中的疑问词+ever引导的名词性从句与no matter+疑问词引导的状语从句的区别6. 考查名词性从句的虚拟语气问题语法要点剖析一、名词性从句主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。
因此，这四种从句通称为名词性从句。
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, why1. 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。
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。

他是怎么成功的仍然是个谜。 How was he successful is still a puzzle. F( ) How he was successful is still a puzzle.T( ) 你能告诉我他住在什么地方吗？ Could you tell me where he lives? ( T ) Could you tell me where does he live?F( )
连接代词: what / who/ which / whose / whatever / whoever / whomever / whichever，
连接副词: where / when / why / how / wherever / whenever。

• 连词: 引导从句，但在从句中不作成分 that ：无词义，不作成分，起连接作用 whether/if：“是否”不作成分，起连接作用

名词性从句讲解在复合句中起名词作用的从句叫做名词性从句。
它包括主语从句、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一. 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。
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 a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…二. 宾语从句名词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。
He told me (that) they could not decide what to do and that they asked my advice.注意：在demand、order、suggest、decide、insist, desire, demand, request, command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：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。
Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
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：He studies English every day. （从句用一般现在时）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）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. 否定转移。
由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。
三. 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。
系动词“感官持续在变化”（默写系动词）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 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四. 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）一．用适当的的关系词填空1．________we understand things has a lot to do with what we feel.2．—I wonder ________Mary has kept her figure after all these years.—By working out every day.3．You have to know ________ you're going if you are to plan the best way of getting there.4．Reading her biography，I was lost in admiration for ________ Doris had achieved in literature.5．I didn't understand ________this would happen and...6．Pick yourself up.Courage is doing ________ you're afraid to do.7．“Every time you eat a sweet，drink green tea.” This is ________ my mother used to tell me.8．Grandma pointed to the hospital and said, “That's ________ I was born.”9．—Is it true that Mike refused an offer from Yale University yesterday?—Yeah, but I have no idea ________he did it; that's one of his favorite universities.10．________ the delayed flight will take off depends much on the weather. 11．The best moment for the football star was________ he scored the winning goal. 12．I think ________ impresses me about his painting is the colors he uses.13．________ struck me most in the movie was the father's deep love for his son. 14．The only way to succeed at the highest level is to have total belief ________ you are better than anyone else on the sports field.15．________ you said at the meeting describes a bright future for the company. 16．From space，the earth looks blue.This is ________ about seventyone percent of its surface is covered by water.17．Do not let any failures discourage you，for you can never tell ________ close youmay be to victory.18．Experts believe________people can waste less food by shopping only when it is necessary.19．It remains to be seen________the newly formed committee's policy can be put into practice.20．It suddenly occurred to him________ he had left his keys in the office. 21．The notice came around two in the afternoon ________ the meeting would be postponed.22．Scientists study________human brains work to make computers.二．语法填空There was a survey on __1__ teachers should receive presents from students among 500 teachers __2__(age) from 25 to 50.Ninety percent of them said that they would be bothered if they got presents from the students or their parents，most of __3__ hoped that parents can be rational and Teachers' Day should be made __4__(ordinarily)．From their point of view，the reason __5__ parents try every means to give presents to teachers is that they don't have enough faith __6__ the teachers if they don't do that.They also suggested that Teachers' Day should be changed to “Teachers' and Students' Day”，__7__ can make teachers and students communicate more __8__(equal) and open-mindedly.What the teachers want most __9__(be) that all the celebration meetings should be cancelled and they are able to have a day off to do __10__ they want.1.________________2.________________3.________________4.________________5________________ 6.________________7.________________ 8._______________9.________________ 10._______________。
