1、1考点 25 名词性从句高考频度：【命题解读】名词性从句是高考的热点，对于名词性从句考纲要求掌握以下内容：掌握主语从句、宾语从句、表语从句的基本用法，了解同位语从句的基本用法。要求考生在复习备考中应该掌握名词性从句的基本用法；一些易混引导词的辨析；句子的语序、否定前移；名词性从句和定语从句、状语从句的辨析等。【命题预测】预计 2018 年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。【复习建议】1. 掌握宾语从句的用法；2. 了解同位语从句的用法；3. 掌握表语从句的用法；4. 掌握主语从句的用法；5. 如何正确选择引导词。考 向 一

2、 名词性从句连接词的用法名词性从句的连接词有从属连词 that/whether/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。That they are good at English is known to us all.The problem is that we dont have enough money.The report that

3、 there will be a severe storm in the northern area is false.(2)一般情况下，宾语从句中的引导词 that 可省略，但在以下几种情况中 that 一般不省略：当 that 从句和主句谓语动词之间有插入语时；2有多个 that 引导的从句时，第一个 that 可以省略，而其他的 that 常不可省略；介词 except，but，besides，in 等后跟 that 引导的宾语从句时；当 when，who，what，where，why，how 等引导的从句与 that 引导的从句作主句谓语动词的并列宾语时。He judged that，

4、because he was a child，he did not understand wine.The reason lies in that she works harder than the others do.Everyone knew what happened and that she was worried.(3)that 和 what 的区别。that 引导名词性从句时，在主从句中不担当任何句子成分，也没有任何含义；而 what 引导名词性从句时，在主从句中都要充当一定的句子成分，what 可以分解成定语从句中的先行词关系代词，即常说的先行词that。Its a shame

5、that he has made such a mistake. I will do what I can (do) to help him.(4)同位语从句与定语从句中 that 的区别。同位语从句中的连接词 that 只起连接作用，在从句中不担当任何句子成分；而定语从句中的关系代词 that 在句中作宾语或主语，与先行词有修饰关系。如果句子是同位语从句，就应用连接词 that 而不能用 which。同位语从句一般放在表具体含义的名词后解释说明名词的含义或内容，如以下名词：news，fact，suggestion，truth，plan，belief，doubt，possibility，ide

6、a 等，而定语从句只是对先行词的限定和修饰。They expressed the hope that they would come to visit China again.(同位语从句)The hope they expressed is that they would come to visit China again.(定语从句) 2.whether 和 if 的用法。 (1)whether 和 if 在宾语从句中可以互换，但是作介词宾语时连接词一般用 whether。It all depends on whether they will come back.(2)后面直接跟 or n

7、ot 时用 whether。I didnt know whether or not he had arrived in Wuhan.(3)主语从句、表语从句中只能用 whether。Whether the meeting will be put off has not been decided yet.The question is whether they have so much money.3(4)whether 可以引导同位语从句，用以说明前面的名词的内容，if 则不能。We ought to discuss carefully the question whether we can

8、do it or not.(5)whether 常与 or 连用表示一种选择，if 不能这样用；whether 也可与动词不定式连用但 if 不能。The question of whether they are male or female is not important.I have not decided whether to go or not.(6)间接宾语位于句首时或者间接宾语提前时用 whether 不用 if。Thank you，but whether Ill be free Im not sure at the moment.(7)whether 可引导一个让步状语从句表示

9、不管、无论，而 if 不能。Whether he comes or not，we will begin our party on time.3.疑问词ever 和 no matter疑问词的区别。(1)疑问词ever 可引导名词性从句，在主从句中要充当一定的成分。Whoever breaks the rule must be punished.You can choose whatever you like in the shop.(2)疑问词ever 还可引导让步状语从句。Whoever breaks the rule，he must be punished.Whatever you do，

10、you must do it well.(3)no matter疑问词只能引导让步状语从句。No matter what you do，you must put your heart into it.No matter who comes late，he must be punished.4.when 和 where 引导的同位语从句与定语从句的区别。when 和 where 前面的名词若是表示时间、地点的名词，则 when 和 where 引导的是定语从句，否则则为同位语从句。They put forward the question where they could get the mon

11、ey.(同位语从句)This is the place where the accident happened.(定语从句)5.名词性从句中 that 不宜省略的几种情况宾语从句或表语从句中 that 有时可以省略，但在以下情况时，that 不宜省略。 （1）当动词后带有两个并列的宾语从句时，引入第二个从句的连词 that 不可省略。如： The teacher told the students (that) they should hand in their homework the next day and that the homework must be signed names b

12、y their parents. 4老师告诉学生他们要在第二天交上作业，并且作业必须由家长签名。 （2）当 that 前面有插入语时，that 不宜省略。如： Little Alice didnt know, Im sure, that her sister was going to America. 我确信，小艾丽斯不知道她的姐姐很快就要去美国了。 （3）省略答语中，that 宾语从句单独出现时，that 不可省略。如： What did he say? 他说了什么 That he would visit the Great Wall. (他说)他将会参观长城。 （4）当主句的状语部分位于

13、that 宾语从句之前时，that 不宜省略。如： Jane realized at once that she must do with it herself. 珍立刻意识到她必须亲自处理那件事。(如省略 that，at once 也可能修饰从句，是表示立刻意识到，还是表示立刻去处理，较为含糊) （5） 当 that 宾语从句中的状语部分位于从句的前部时，that 不宜省略。如： Tom promised that if he could earn as much as 500 dollars in this month, he would buy a computer for his br

15、hat 不宜省略。如： Mary has made up her mind that she will study hard for the scholarship, so she can have the chance to go abroad for further study. 玛丽下定决心努力学习以获得奖学金资格，这样她就有机会出国深造了。 （9）当 that 宾语从句前有 it 作其形式宾语时，that 不可省略。如： We think it important that college students should master at least one foreign lang

16、uage.我们认为大学生至少掌握一门外语是很重要的。 （10）当引导同位语从句时，that 一般不可省略，尤其当 that 与先行词处于分割情况时。如： He heard the news that his team had won. 5他听到了他的队获胜的消息。 There is a feeling in me that they are cheating me. 我有一种感觉他们在骗我。 （11）当 that 宾语从句的主语是非谓语动词或是主语从句时，that 不可省略。如： The doctor said that taking exercise was the best way of

17、losing weight. 医生说运动是最好的减肥方式。 考 向 二 主 语 从 句 1.主语从句在复合句中充当主语，大多数主语从句都可以用 it 作形式主语而把主语从句置于句尾。2.that 引导主语从句时可用 it 作形式主语，that 不可省；what 引导的主语从句表示的东西时，一般不用 it 作形式主语；whatever，whoever，whichever 一般也不用 it 作形式主语。That she will succeed is certain.It is certain that she will succeed.注意：(1)在It is necessary/importa

18、nt/strange/natural.that 从句结构中，从句谓语常用(should)动词原形形式。【拓展延伸】主语从句的引导词引导词 作用 引导词 作用that 无词义，在从句中不充当成分，但不能省略 how 多么，怎样，作方式状语或程度状语常见的 it 替代 that 引导的主语从句的句式主要有以下几种：(1)It系动词形容词(necessary，right，likely，unlikely，wrong，important，certain，clear，obvious，strange，normal 等)that 从句It is certain that most of the farmers
