名词性从句主语从句

主语从句

导入：观察并指出句子成分

A tree has fallen across the road.

You are a student.

To find your way can be a problem.

Smoking is bad for you.

一．概念：

主语：主语是指句子谈论的主题，说明的人或事物。也就是句中动作、行为、性质和状态的主体，一般位于句首

主语从句：在句中充当主语的从句

二·基本结构

关系词简单句谓语动词宾语同位语

That he finished writing the composition in such a short time surprised us all.

他在很短的时间内写完作文让我们都很惊讶

三关系词(引导词)

1．从属连词：that whether

that 引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。

That she left him cut him to the heart.

That he will come is certain.

注意：有时为了使句子结构平衡, 避免“头重脚轻”, 常用 it 作形式主语, 而把从句放在后面。E.g

That she has made such a mistake is a pity.

It is a pity that she has made such a mistake.

这样就构成了下面一些常用句型:

1) It is + adj. +从句

It is necessary that… 有必要…

It is important that …. 重要的是…

It is obvious that…… 很明显……

2) It +不及物动词+从句

It seems/appears that... 似乎……

It happened that... 碰巧……

It occurred to me that…… 我突然想起……

3) It + be +过去分词+从句

It is said that... 据说……

It is known to all that... 众所周知……

It is reported that... 据报道……

It is believed that... 据信……;人们相信……

It is suggested that... 有人建议……

It must be pointed out that... 必须指出……

It has been proved that... 已证明…….

4) It is + n. +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……

由whether及其他连词引导的主语从句放在句首，句后都可。

Whether it will please them is hard to say.

It is hard to say whether it will please them.

2.连接代词：who whoever whom whose what whatever which whichever What seems easy to some people seems difficult to others.

Which side will win is not clear.

注意：what 与that 在引导主语从句时的区别

what 引导主语从句时在从句中充当句子成分, 如主语、宾语、表语, that 则不充当任何成分无意义。

例如：What you said yesterday is right.

That she is still alive is a consolation

1一个句子作主语时，主句的谓语动词应为单数。

Eg Whether he will come depends on the weather.

2 what 引导的句子作主语时，谓语动词的数由句子的内容决定（即由表语决定)。

What I want is money.

What we need are good books

What he said is reasonable.

What we will do hasn’t been decided.

3 Where he was born and where he lives now are not clear.

Where and when he was born remains a secret.

两个或两个以上的主从联合做主语，主句谓语动词应为复数。

两个或两个以上的连词引导一个从句，主句谓语动词应为单数。

4 Whether he will come isn’t clear. (不能换成if)

It isn't clear whether /if he will come. (可以与if进行替换)

（if不能置于句首）

5. It 作形式主语和it引导强调句的比较

①主语从句常用it作形式主语，一般常用句型为：It is+{名词/形容词/过去分词}+主语从句例如：

It is still a question whether she will come or not.

It is strange that you should like him.

It is still unknown which team will win the match.

另外，还有一些比较多见的结构：

It turned out that……;

It has been proved that……;

It happened/occurred that……;

It is well-known that……等等

②而强调句则不同，它的结构是：It+be+被强调部分+that+从句

强调主语：It is the times that produce their heroes.时势造英雄

强调宾语：It is English that Prof.Lin teaches us.

强调状语：It was in shanghai that I saw the film.

判断是否是强调句有一个方法，就是将that以后的“句子的其余部分”拿出来单独看，看有没有缺成分，缺的是什么成分，再把谓语动词后面that前面的那部分，带到你认为缺成分的地方，如果放进去是一句完整的句子了，那就说明是强调句。

6. 用于It is important / natural / necessary / impossible that...句型中, 主语从句应使用虚拟语气, 谓语动词用\“should + 动词原形\”的形式, should有时有感情色彩。

It be suggested/ advised/ ordered/requested that sb (should) do sth…

2016考研英语：主语从句

在句子中起名词作用的句子叫名词性从句。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，名词性从句又可分为主语从句、宾语从句、表语从句和同位语从句。今天我们就来重点讲一下其中的主语从句。 在复合句中充当主语成分的句子叫作主语从句。它的具体表现形式是：引导词引导一个从句作主语；或者it作形式主语+谓语/系表结构+引导词+从句。 【例1】that That Chris Lee won the champion of Super Girl in 2005 arouse wide public concern.李宇春赢得2005年超女冠军这件事引起了社会的广泛关注。 【例2】what What caused the accident remains unknown.是什么引起了这一事故仍然未知。 【例3】where Where my wife and I should choose to continue my further education is a question of great importance.我太太和我应该去哪享受我们的蜜月还没有最后决定。 【例4】which Which university I should choose to continue my further education is a question of great importance.我应该考哪个大学的研究生是个很重要的问题。 【例5】when When and where the test will be given is not yet decided.什么时候在什么地方进行考试还没定下来。 【例6】-ever Whoever gets the job will have a lot of work to do.任何得到这份工作的人都将要有很多工作要做。 【例7】how How we can protect the grain from damp needs to be discussed.我们怎样才能保护粮食不受潮需要讨论。 【例8】whether Whether this is true or not remains a mystery.这是对是错还是个谜。 It句型 有的时候主语从句过长，根据人类短暂记忆规律，主语过长会影响理解和阅读，往往会用it作形式主语，而把真正的主语放在句尾，加以强调，是为it句型。 【例】 It is a pity that we won’t be able to go to the south to spend our summer vacation.我们不能去南方度过我们的暑假很遗憾。 为表示强调，常以形式主语it引导从句。It+谓语+引导词+从句。由于主语从句一般被认为是单数形式，形式主语代表真正的主语，因此要用it。因此形式主语的谓语动词、be动词+表语均为第三人称单数形式或过去式。 英国桂冠诗人约翰·梅斯菲尔德说：“快乐的日子使人睿智。”很多考生可能觉得这句话应该反过来说，但其实复习过一段时间以后，面对着越来越复杂的难题，你就会发现，保持快乐的心态，复习效率自然而然就会提高。

高中英语语法--主语从句复习

主语从句 1）主语从句定义：在句子中担当主语的是一个从句，这个从句就叫做主语从句。 主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。 主语从句主要有三类： （1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。 例如：That you will win the medal seems unlikely. 你想获得奖牌看起来是不可能的。 That you are so indifferent bothers me. 你如此冷淡使我很烦恼。 That she survived the accident is a miracle. 她在事故中幸免于难简直是奇迹。 （2）用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。 例如：Whether she is coming or not doesn’t matter too much. 她来不来都无关紧要。 （3）用连接代词引导的主语从句(在由连接代词who, whose, whom, which, what, whoever, whomev er, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分). 例如：What you need is more practice. 你所需要的是更多的训练。 What I want to know is this. 我想知道的就是这事。 Whatever we do is to serve the people. 我们无论做什么都是为人民服务。 （4）用连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。) eg:Where we should leave it is a problem. When they will come hasn’t been made pubic. 他们什么时候来还不知道。 注意点: 1.it 做形式主语,而将主语从句放在句末（尤其是当谓语较短时）。 例如：That light travels in straight lines is known to all. 光沿直线传播，这是众所周知的事。 =It is known to all that light travels in straight lines. 众所周知光沿直线传播。 When the plane is to take off has not been announced . 飞机何时起飞还没有宣布。 = It has not been announced when the plane is to take off. 还没有宣布飞机何时起飞。 (当what引导的主语从句表示“…的东西”时，一般不用it作形式主语。) 错:It is a book what he wants. 对:What he wants is a book. 他想要的是本书。 例如：Has it been settled who will be sent to carry out the task ? 谁将被派去执行这项任务决定了吗？ 固定用法和译法 （1） It is +名词+从句

新概念英语语法-主语从句 1.that引导主语从句 that引导主语从句时不同于其他的连词，既无词义也不作成分， 只起单纯的连接作用，且通常不能够省。为了强调that引导的主语从 句而置之于句首时，that不可省。 ①That the driver could not control his car was obvious. ②That she was chosen made us very happy. ③That he will come is certain. ④That he would take the risk is true. ⑤That he should have married her isn't surprising. ★通常，that引导主语从句时用it做形式主语，把从句置于句尾，此时that有时可省。例如： ①It was obvious that the driver could not control his car. ②It made us very happy that she was chosen. ③It i s certain that he will come. ④It is true that he would take the risk. ⑤It isn't surprising (that) he should have married her. ★如果以that从句为主语的句子是疑问句，就只能用先行词it 结构。例如： ①Is it certain that he will come? ②Is it true that he would take the risk?
