2021高考英语一轮统考复习第二部分高考重点语法突破专题二第2讲名词性从句学案新人教版

2021年高考英语一轮复习语法精讲精练名词性从句用法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。

高考常从连接词的选择、语序、语气、时态等方面来考查。

名词性从句中的连接词有连词that / whether / as if，连接代词what / who/ which /whose / whatever / whoever / whomever / whichever，连接副词where /when /why / how / wherever / whenever。

第1讲引导名词性从句的连接词考点1.引导名词性从句的连接词有哪些有学生认为，引导同位语从句只能用that, 这句话对吗？先看下面几个句子。

①I have no question that he will e.②I have a question whether he will e③I have a question when he will e.我们可以看出：上面三个句子中question 后面都是同位语从句，都是说明question 的内容的。

在句①中，同位语从句的原句是陈述句，由that引导；在句②中，原句是一般疑问句，由whether引导；在句③中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。

其实，所有名词性从句的连接词都有上面的三种情况。

宾语从句：I don’t know that he will e.I don’t know whether/if he will e.I don’t know when he will e.表语从句：What I don’t know is that he will e. What I don’t know is whether he will e. What I do n’t know is when he will e.主语从句That he will e is obvious.Whether he will e isn’t known yet. When he will e isn’t known yet.1.【xx浙江】It is uncertain ______ sideeffect the medicine will bring about, although about two thousand patients have taken it.2.A. that B. what C. how D.whether3.【xx全国新课标】It is by no means clear______ the president can do to end the strike.4.A. how B. which C. that D. what5.【xx山东】It doesn’t matter ______ youpay by cash or credit card in this store. 6.A. how B. whether C. whatD. why7.【xx陕西】It remains to be seen ______the newly formed mittee’s policy can be put into practice.8.A. that B. which C. whatD. whether9.【xx天津】It is obvious to the students______ they should get well prepared for their future.10.

1.依照语境考查不同连接词的辨析Why not try your luck downtown, Bob? That's____ the best jobs are.where在此引导表语从句，表示“……的地点”。

又如：This is where the river is the deepest.这是河流的最深处。

This is where I first met her.这确实是我初次与她会面的地点。

2.考查what的用法(1)____matters most in learning English is enough practice.what在此引导主语从句，相当于the thing that。

(2)____parents say and do has a life-long effect on their children.what在此引导主语从句，相当于the thing that~3.依照句法功能考查连接词的选用Choosing the right dictionary depends on_______you want to use it for.what用以引导宾语从句，用作介词on的宾语，其中的what在从句中用作介词for的宾语。

4.考查whatever等的用法Could I speak to____is in charge of International Sales, please?whoever有两个要紧用法：一是用于引导名词性从句，其意思相当于the person who;二是用于引导状语从句，其意思相当于no matter who。

句中的whoever引导宾语从句，用作介词to的宾语，5.在复杂结构中考查名词性从句的使用Having checked the doors were closed, and____all the lights were off, the boy opened the door to his bedroom.that在此用于引导宾语从句，用作动词check的宾语。

高考英语语法专题复习讲义-名词性从句 2语法复习专题（一）名词性从句一、考点聚焦1、名词性从句中连接词的运用名词性从句中的连接词有连词that / whether / as if，连接代词what / who/ which / whose / whatever / whoever / whomever / whichever，连接副词where / when / why / how / wherever / whenever。

（1）that的用法。

①主语从句、表语从句、同位语从句中用that但不能省略。

如： That they are good at English is known to us all. The problem is that we don’t have enough money.She expressed the hope that they would come to China one day.②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 wine Everyone knew what happened and that she was worried.The reason lies in that she works harder than the others do.③that从句作主语和宾语时，可以用it 来替换成以下几种结构表达。

(A)It is clear/certain/likely/true/surprising that… （B）It is a pity/shame/goodidea/no wonder that ...（C）It is said/reported/believed/known/thought/suggested that … （D）It seems/happens that。

一、几种易混的从句的差异定语从句、名词性从句和状语从句有时分在方法上很类似，下面供给一些差异的办法：1．定语从句与同位语从句定语从句与前面的名词是润饰与被润饰的联系；而同位语从句是用来阐明前面名词的内容的。

that在定语从句中充任语句成分，可指物或人；而同位语从句中的that在从句中不充任任何语句成分，只起衔接效果。

请比较：1.The news (that/which) he told us wasexciting.(定语从句，that/which在从句中作宾语，还能够被省掉)2.The news that our team has won isexciting.(同位语从句，that从句是阐明news的内容的，that在从句中不作任何成分，但不能被省掉)剖析判别是定语从句仍是同位语从句能够用“加词”的办法，即在名词和从句之间参加一个be动词，假如语句意思建立，则是同位语从句，不然，则是定语从句。

如上面第二句，加上be动词后：The news is that our team has won.语句意思建立，所以是同位语从句。

而榜首句，加上be动词后：The news is that he told us.意思不建立，因而不是同位语从句。

【特别提示】一般情况下，同位语从句紧跟在它所阐明的名词的后边，可是有的时分，为了表达的需求，名词与从句之间被别的一些内容分隔开了，叫做“分隔同位语从句”。

关于这类同位语从句，必定要依据句意，找准它所阐明的名词。

2．定语从句与状语从句请看两组语句：榜首组：差异such...as...和such...that...1.The new storybook is written in sucheasy English as beginners can understand.2.The new storybook is written in sucheasy English that beginners can understand it.这两句话只要一词之差，但语法结构截然不同：榜首句是as引导的定语从句，as相当于that/which(但不能用that/which)，在从句中作understand的宾语。

名词性从句名词性从句包括主语从句、表语从句、宾语从句、同位语从句。

其关联词有连接词that，if，whether;疑问代词who，what，which和疑问副词when，where，how,why等。

1.主语从句主语从句在句中做主语。

它可以放在主句谓语动词之前，但多数情况由it作形式主语，而把主语从句放在主句之后。

例如:Who did that is known to all.It is interesting that you should like him。

2.表语从句表语从句在句中作表语，位于主句中的系动词之后。

如：The question is who can complete the difficult task。

表语从句不能用if引导，但可用as if引导.例如：He looked as if he was going to cry．3.同位语从句同位语从句跟在名词后面，进一步说明该名词的具体内容。

引导同位语从句的名词主要有fact，news，promise，idea,truth等.连接词用that（不用which），及连接副词how,when，where，why等。

例如：His delay is due to the fact that the car went wrong halfway．The news that our team has won the match is true.She asked the reason why there was a delay．4.宾语从句1.宾语从句在句中作及物动词或介词的宾语。

解密09名词性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。

其主要考察：1.了解名词性从句的基本用法，掌握名词性从句的引导词及引导词在名词性从句中的作用，辨析that与what,if 与whether等引导词的用法。

2.明确it作形式主语和形式宾语、代替主语从句及宾语从句的用法，及其与强调句的区别。

3.区分that引导的同位语从句及定语从句。

【备考建议】高考对名词性从句的考查仍然不会单纯地考查其语法结构，而是将其融入一定的语境中来考查考生的实际综合运用能力。

分析历届高考试题名词性从句考查的焦点，复习主要应该从以下六个方面着手：1.名词性从句的语序问题2.引导词that与what的区别（that在从句中不充当成分，what在从句中作主语、宾语或表语）3. it在名词性从句中作形式主语或形式宾语的用法4. whether与if的区别no matter+疑问词引导的状语从句的区别5.名词性从句中的疑问词+ever引导的名词性从句与（1）引导词：从属连词that, whether；连接代词who, what, which；whoever, whatever, whichever;连接副词when, where, how和why。

（2）语序：陈述句语序（3）在主语从句中只能用whether,不能用ifThat he will win the match is certain.It is certain that he will win the match.注意：一般来说主语从句都是放在句首，但有时为了使句子保持平衡，避免"头重脚轻",常用it 作形式主语，从而把主语从句放后面。

常以it作形式主语的句型有：①It is＋形容词＋that...☞It is certain that she will do well in her exam．毫无疑问她考试成绩会很好。
