2019届二轮复习语法专题名词性从句考点解读
近几年语法填空与短文改错题中对名词性从句的考查多集中在宾语从句上，这也与高考重基础知识的考查这一主题思路相符；名词性从句是英语语法中一个重要组成部分，也是英语语言中运用最为广泛的知识点之一，对其涉及的所有知识都应重点掌握。
考生在解答这类题目时，要根据连接词在名词性从句中所作的句子成分来确定选用什么连接词。若在从句中作主语或宾语用连接代词，若作状语就用连接副词；如果不作成分则要考虑从句意思是否完整，是否需要用whether/if；如果不作成分且从句意思完整则用that。
[典题感悟](考什么、怎么考)
一、语法填空常考点
(一)宾语从句
1．(2015·全国卷Ⅱ)As natural architects, the Pueblo Indians figured out exactly ________ thick the adobe walls needed to be to make the cycle work on most days.
解析：how how thick the adobe walls needed to be是宾语从句，作figured out的宾语。how修饰形容词thick。
2．(2014·广东高考)I didn’t understand ________ this would happen and my credit card had already been charged for the reservation.
解析：why 根据语境此处应用why引导宾语从句。
(二)主语从句
1．(2016·江苏高考改编)It is often the case ________
anything is possible for those who hang on to hope.
解析：that 句意：通常情况下，对于那些坚持梦想的人，一切皆有可能。此句为主语从句，从句中不缺少任何成分，句意完整，故使用that引导。
2．(2015·北京高考改编)______ we understand things has a lot to do with what we feel.
解析：How 句意：我们如何理解事情与我们的感受有很大关系。本句考查主语从句，根据逻辑意义此处表示方式，故填how。
(三)表语从句
1．(2016·北京高考改编)The most pleasant thing of the rainy season is ________ one can be entirely free from dust.
解析：that 句意：雨季最令人高兴的事情就是你完全可以远离尘埃。根据句子结构可知，本句是表语从句，且表语从句中主系表结构完整，故使用连词that引导表语从句，that在表语从句中不作句子成分，只起连接作用。
2．(2015·安徽高考改编)A ship in harbor is safe, but that’s not ________ ships are built for.
解析：what 句意：港口里的船是安全的，但是那不是建造船的目的。空格后的句子是表语从句，表语从句中for缺少宾语，故用what。
(四)同位语从句
1．(2016·天津高考改编)The manager put forward a suggestion ________ we should have an assistant. There is too much work to do.
解析：that 句意：经理提出了一个建议，我们应该有一个助手。
有太多的工作要做。后面是建议的具体内容，从句不缺成分，故填that。
2．(2014·重庆高考改编)—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.
解析：why 句意：“迈克拒绝了耶鲁大学的录取通知是真的吗？”“是的，但我不知道他这么做的原因，耶鲁大学是他最喜爱的大学之一。”根据后面的that’s one of his favorite universities 可知这里指原因，故用why引导。
二、短文改错常考点
(一)连接代词和连接副词混用
1．(2015·全国卷Ⅱ)After looking at the toy for some time, he turned around and found where his parents were missing.________________
解析：where→that或者去掉where 此处指他转过身发现父母不见了。found后面接宾语从句，故将where改为that或去掉where。
2．(2013·湖南高考改编)Do not let any failures discourage you, for you can never tell that close you may be to victory.________________
解析：tha t→how句意：不要因失败而泄气，因为你永远也不会知道成功可能离你有多近。“...close you may be to victory”为宾语从句，close为形容词，故用how。
(二)连接词重叠使用
1．(2014·四川高考)If you notice that when someone is
missing or hurt, tell your teacher immediately.________________
解析：去掉when notice后的宾语从句不缺成分且意思完整，故用that引导。
2．The exhibition tells us what why we should do something to stop air pollution.________________
解析：去掉what 根据语境可知这里表示原因，故要用why来引导。
(三)连接代词/副词混用
1．(2013·辽宁高考)“He has ruined his healthy. We are worried about him.” That is which other teachers say.________________
解析：which→what此处表示其他老师的说话内容，且连接词引导表语从句并在从句中作宾语，故用what。
2．We must find out where Karl is coming, so we can book a room for him.________________
解析：where→when根据语境可知，此处表示“他来的时间”，故用when引导。
[谨记规律](为什么、怎么办)
1．掌握名词性从句连接词的基本用法
(1)连接词that在从句中没有任何含义，只起连接作用，不作任何成分。
(2)连接词whether, if意为“是否”，只起连接作用，不作任何成分。若在两者之间二选一，应选择whether。
(3)连接代词who, whom, whose, what, which, who(m)ever, whatever, whichever既起连接作用，同时又在从句中充当主语、宾语、表语、定语等成分。
(4) 连接副词when, where, why, how既起连接作用，同时又在从句中作状语。
2．牢记what和that的区别
(1)that没有词义，也不作任何成分，当从句意义完整，不缺任何成分时用that；
Experts believe that people can waste less food by shopping only when it is necessary.
专家认为，人们可以通过只有需要时才购物这一方法来减少更多食物的浪费。
(2)what在从句中表示“……的(东西)”(有时候可以不译)，在从句中充当主语、宾语、表语，定语等成分。
Pick yourself up. Courage is doing what you’re afraid to do.
振作起来。勇气就是去做你害怕去做的事情。
3．熟记it作形式主语代表从句的句型公式
(1)It＋be＋形容词(necessary/right/likely/unlikely/wrong/important/certain等)＋that从句
It is certain that most of the farmers have brought in more money by all means.
很明确，大多数农民通过各种方式赚了很多钱。
(2)It＋ be＋名词(短语)(a pity/a shame/no wonder等)＋
that从句
It is a pity that you didn’t attend the lecture yesterday.
你昨天没参加讲座真是遗憾。
(3)It＋be＋过去分词(said/reported/decided等)＋that从句
It is said that the professor has already succeeded in carrying out this experiment.
据说这位教授已经成功地完成了这个实验。
(4)It＋特殊动词(seem/appear/happen等)＋that从句
It seems to me that you object to the plan.
在我看来，你好像反对这个计划。
4．熟记it作形式宾语代表从句的常见句式
(1)动词find, feel, think, consider, believe等后有宾语补足语时，需要用it作形式宾语而将宾语从句后置。
I think it necessary that we drink plenty of boiled water every day.
我认为每天多喝开水是有必要的。
(2)有些动词跟从句时习惯上需要在从句前加it，这类动词有：hate, enjoy, like, love, dislike, appreciate, see to等。
Please see to it that the door is locked.
请留意一下把门锁好。
5.牢记连接词的选择3步骤
(1)若两个句子(有两个主谓结构)之间，或者两个单词以及短语中间，没有句号或分号，也没有连词，那空格处通常是填连接词，否则，句子结构就不完整。
(2)根据两句之间的意义和逻辑关系，或者根据句式结构，确定
是并列句还是某种主从复合句。
(3)一旦判断是名词性从句，就根据名词性从句中缺少什么句子成分来确定选用什么连接词，若从句中缺少主语、宾语或表语时，用连接代词，若作状语就用连接副词；如果不缺少成分则要考虑意思是否完整，是否需要用whether/if；如果不缺少成分且意思完整用that。
What was most important to her, she told me, was her family.(引导主语从句，在从句中作主语)
她告诉我说，对她来说最重要的是她的家庭。
When the news came that the war broke out, he decided to serve in the army.(引导同位语从句)
当战争爆发的消息传来时，他决定去参军。
I don’t know who will be in charge of the company when the manager is away.(引导宾语从句，在从句中作主语)
我不知道当经理不在时由谁来负责公司。

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

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.

名词性从句 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 不可省略的连词： a. 介词后的连词 b. 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： a. whether引导主语从句并在句首 b. 引导表语从句 c. whether从句作介词宾语 d. 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. （二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesn’t matter so much whether you will come or not. 用it作形式主语的that-从句有以下四种不同的搭配关系： a. It + be +形容词+ that-从句 It is necessary that…有必要…… It is important that…重要的是…… It is obvious that…很明显…… b. It + be + -ed 分词+ that-从句 It is believed that…人们相信…… It is known to all that…从所周知…… It has been decided that…已决定…… c. It + be +名词+ that-从句 It is common knowledge that………是常识 It is a surprise that…令人惊奇的是…… It is a fact that…事实是……
名词性从句 名词性从句包括宾语从句、主语从句、表语从句、同位语从句。 名词性从句一共有三种：1）that从句；2）whether从句；3）疑问词所引导的从句。 分项说明如下： 1）that从句 任何一个主语起首的陈述句前面冠以that，即成that从句。 He enjoys dancing.

高考英语语法复习三:名词性从句 名词性从句相当于名词,可分别作主句的主语、表语、宾语和同位语。因此,名词性从句可分为主语从句、表语从句、宾语从句和同位从句。 (一引导名词性从句的连接词 1、连接代词:who, whose, whom, what, which。有词义,在从句中担任成分,如主语、表语、宾语、或定语等。 2、连接副词:when, where, why, how。有词义,在从句中担任成分,作状语。 3、连接词:that, whether, if, as if。that 无词义,在从句中不担任成分,有时可省略; if (whether, as if虽有词义,但在从句中不担任成分。 注意:连接代词与连接副词在句中不再是疑问句,因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分,连接词whether 和if(是否,as if(好象在从句中不充当句子成分,只起连接作用。根据句义,如果连接代词与连接副词,whether、if 和as if 都用不上时,才用that作连接词(that本身无任何含义。 (二主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语,主语从句放在句末。 e.g. It doesn't matter so much whether you will come or not. 3、that引导主语从句时,不能省略。 e.g. That he suddenly fell ill last week made us surprised. (三表语从句 1、表语从句在复合句中作表语,位于系动词之后。 e.g. The question was who could go there. 2、引导表语从句的连接词that有时可省去。 e.g. My idea is (that we can get more comrades to help in the work. (四宾语从句 1、宾语从句在复合句中作宾语。引导宾语从句的连词that一般可省略。 e.g. I hope (that everything is all right. 2、介词之后的宾语从句,不可用which或if连接,要分别用what或whether。 e.g. I'm interested in whether you've finished the work.. I'm interested in what you've said. 3、whether与if都可以引导宾语从句,常可互换。但下面情况不能互换。 ①宾语从句是否定句时,只用if,不用whether。 e.g. I wonder if it doesn't rain. ②用if 会引起误解,就要用whether。 e.g. Please let me know whether you want to go.(此句如果把whether改成if,容易当成条件句理解 ③宾语从句中的whether 与or not直接连用,就不能换成if;不直接连用,可换。 e.g. I don't know whether or not the report is true.
