名词性从句详解及练习
各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。
上述这四种从句均被称为名词性从句。
所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。
另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。
下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。
例如：That he will come to the discussion is certain.他来参加讨论是确定的。
That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。
When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。
主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。
例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。

这分三种情况:(1)对于以连词thatgl导的主语从句，通常用形式主语代主语从句:It’s a pity that he didnt come.很遗憾他没来。
(2)对于以连接代词(副词)引导的主语从句，可以使用形式主语代主语从句，也可直接在句首使用主语从句:Whether they wouldsupport us was a problem.他们是否会支持我们还是一个问题。
It was a problem whether they would support us.他们是否会支持我们还是一个问题。
(3)对关系代词型what引导的主语从，通常不用形式主语，总是主语从句放在句首:What we need is money.我们需要的是钱。
What I want to know is this.我想知道的就是这一点。
(4)如果句子是疑问句，则必须用带形式主语it的结构:Is it true that he is the girl's father? 他是那女孩的父亲，是真的吗?How is it that you are late again? 你怎么又迟到了?3.连词that的省略问题引导主语从句的连词that有时可省，有时不能省，其原则是:若ha导的主语从句直接位于句首，则ha不能省略;若hat引导的主语从句位于句末，而在句首使用了形式主语it，则that则可以省略: That you didn’t go to the talk was a pity. 很遗憾你没去听报告。
中考考点_名词性从句知识点汇总(全)经典
中考考点_名词性从句知识点汇总(全)经典一、名词性从句1．_____Macao has achieved shows _____"one country, two systems" principle is the best solution to the Macao and Hongkong question, left by history.A. That; whatB. What; thatC. What; whatD. That; that【答案】 B【解析】【分析】句意：澳门取得的成就表明，“一国两制”原则是解决历史遗留下来的澳门和香港问题的最好办法。
分析句子可知，_____Macao has achieved为主语从句，从句中achieve缺少宾语，所以第一个空用what来充当宾语。
再分析句子可知，shows后接宾语从句，从句句意和结构完成，所以第二个空应填连接词that。
故选B。
【点评】考查名词性从句，本题涉及what引导的主语从句和that引导的宾语从句。

本句时一个主语从句，it作形式主语，真正的主语为that what plays a vital role in driving away one's anxiety is one's sweet childhood memories.，主语从句中又有一个主语从句，且此主语从句中缺少主语，所以用what引导。

中考英语复习专辑——:名词性从句十二、语法复习:名词性从句(主语从句,宾语从句, 表语从句, 同位语从句)主语从句主语从句的语序主语从句要求使用陈述句语序，而非一般疑问句语序。
如：What surprised me most was that the little girl could play the violin so well.How he was successful is still a puzzle.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。
如：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的选用引导主语从句，不能用if，只能用whether。
如：Whether we will hold a party in the open air tomorrow depends on the weather.我们明天是否在户外开晚会要看天气而定。
（3）其它连接代词和副词的选用根据主语从句的具体意义，正确的选择who, which, when, where, why, how等连接词，这些连接词既有疑问含义，又起连接作用，同时在从句中充当各种成分。
如：When we shall hold our sports meet is not decided. 我们何时举行运动会还没有决定。
Who broke the glass yesterday is not clear. 还不清楚昨天谁打破了玻璃。
Which car you will choose to buy makes no difference. 你决定买哪一辆车都不会有任何区别。
（4）whatever / whoever的功用whatever, whoever在主语从句中不含疑问意义。
它引导主语从句，并在从句中作主语、宾语、表语等。
whatever = anything that; whoever = anyone who。
要注意和whatever, whoever引导的让步状语从句的区别。
如：Whoever breaks the law should be punished. （主语从句）（＝Anyone who breaks the law should be punished. ）Whoever breaks the law, he should be punished. （让步状语从句）（＝No matter who breaks the law, he should be punished. ）it构成的主语从句（1）由连词that引导的主语从句，在大多数情况下会放到句子的后面，而用代词it作形式主语。
谓语是seem, appear, be certain, be a pity, be a wonder, be one's hope, be likely等词或短语时。
It is well-known that the earth moves around the sun. 众所周知，地球围绕太阳转。
需要注意的是，it作形式主语代替主语从句时，要注意和as引导的定语从句的区别。
试比较：It was reported that the US was under the terrorist attack. （主语从句，有that，无逗号）As was reported, the US was under the terrorist attack. （定语从句，无that，有逗号）上两句意为“据报道，美国遭到恐怖分子的袭击”。
用于It is suggested / required / ordered / demanded that...句型中,动词为表示命令、建议、要求等意义的词。
主语从句应使用虚拟语气,谓语动词用"should + 动词原形",should可以省略。
例如:It is suggested that you (should) spend more time in studying English. 你应该花更多的时间学习英语。
（2）常见用it作形式主语的复合句结构1.It is a fact （a good idea / a pity / a shame / no wonder / good news…）that…如：It's a pity that you missed the film. 你没有看那部电影真是太遗憾了。
2. It is necessary （clear / true / strange/ important /wonderful / possible / likely…）that…需要注意的是，这类主语从句中，谓语动词很多为“（should）＋动词原形”，即要用虚拟语气。
如：It is necessary that you （should）master the computer. 你很有必要掌握电脑。
It is important that a student learn English well. 学生学好英语很重要。
It's clear that they badly need help. 很明显，他们急需援助。
It is likely that a hurricane will arrive soon. 飓风很可能马上就要到达了。
3.It is reported （well-known / hoped / thought / expected /said /believed/decided /suggested /ordered…）th at…如：It is said that he was killed in the earthquake. 据说他在地震中丧生了。
4.It seems （happened / appears / doesn't matter / makes no difference / …）that …如：It seems that they will win the game. 看起来他们好像会赢得这场比赛。
It makes no difference whether he will attend the meeting or not. 他是否会参加会议都无关紧要。
The Foreign Minister said, "________ our hope that the two sides will work towards peace."A. This isB. There isC. That isD. It is句式用形式主语it引导的主语从句相当多，有些已形成固定的语法和译法。
常见的有：It is said that... 据说…… It is reported that... 据报导……It is well known that... 众所周知…… It is announced that... 据宣布……It is believed that... 人们相信…… It is thought that... 人们认为……It is understood that... 自不待言…… It must be pointed out that... 必须指出……It must be admitted that... 必须承认……否定转移1) 将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I don't think I know you.我想我并不认识你。
I don' t believe he will come.我相信他不回来。
注意：若谓语动词为hope,宾语从句中的否定词不能转移。
I hope you weren't ill. 我想你没有生病吧。
2) 将seem, appear 等后的从句的否定转移到前面。
It doesn't seem that they know where to go.看来他们不知道往哪去。
It doesn't appear that we'll have a sunny day tomorrow. 看来我们明天不会碰上好天气。
3) 有时将动名词，介词短语或整个从句的否定转变为对谓语动词的否定。
I don't remember having ever seen such a man.我记得从未见过这样一个人。
(not否定动名词短语having…)It's not a place where anyone would expect to see strange characters on the street. 在这里，人们不会想到在街上会碰上陌生的人。
(anyone 作主语，从句中的谓语动词不能用否定形式。
)4) 有时状语或状语从句中否定可以转移到谓语动词前。
The ant is not gathering this for itself alone.(否定状语)蚂蚁不只是为自己采食。
He was not ready to believe something just because Aristotle said so. (否定because状语) 他并不因亚里斯多德说过如何如何，就轻信此事。
She had not been married many weeks when that man's younger brother saw her and was struck by her beauty.(否定状语many weeks)她结婚还不到几个月，这个人的弟弟就看见她了，并对她的美貌着了迷。
