从句做主语（通用9篇）

篇1：从句做主语

英语从句的重点是，熟悉连接从句的连词、关系词的各种含义和用法。

(1)名词性从句(归属于名词类)：

主语从句

表语从句

宾语从句

同位语从句

(2)形容词性从句(起描绘名词的修饰作用，归属于形容词类)：

定语从句

(3)副词性从句(起描绘谓语动词的修饰作用，归属于副词类)：

状语从句

名词性从句

主语从句——一般们于句子的开头，以从属连词引导。

•连接主语从句的连词

纯连词：that(不有词义，只起连接作用，在从句中不充当成分)

whether

连接副词：when, where, how, why

连接代词：what, whatever, who, whoever, which

That Jack got an A for his physics is a surprise.

杰克的物理得了优秀真是令人惊喜的。

That July went to New York is no news now.

朱莉去纽约一事可不是什么新闻了。

注意，此类主语从句通常必成以下形式，显得更平衡自然一些：

It is surprise that Jack got an A for hisphysics.

It is no news now that July went to NewYork.

此类从句中的that是不能省略的，因为省去that后就不看出是从句了。

Whether she agrees or not is nothing to me.

她是否同意对我毫无影响。

Whether we come or not depends on the weather.

我们是否来取决于天气。

此类主语从句中的whether既起连接作用，又有意思，不能省略。

特别需要注意的是：

用whether引导的主语从句，不能使用if代替：

×If she agrees or no is nothing to me.

×If we come or not depends on the wether.

When we set out is not decided yet.

我们何时出发还没定下来呢。

How she succeeded remains a secret.

他怎么成功的仍然是一个秘密。

Where Bob chooses to stay is up to him.

鲍勃选择在哪里居住由他自己决定。

What the teacher stressed will be in the exam paper.

老师强调的内容会出现在考卷中。

Who is the new teacher matters a lot.

谁当新教师关系可大了。

篇3：英语主语从句用法剖析

一、主语从句概述

在主从复合句中充当主语的一个句子就叫主语从句, 例如:That the earth goes round the sun is well-known to everybody.

Whether she will come to help us has not been known yet.

When we will go to Beijing for visa to America is still a secret.

二、主语从句中的主谓一致

当主语从句作一个主从复合句的主语时,主句的谓语动词通常用单数,但what引导的主语从句中谓语动词是need, want,require等的时候,主句谓语动词和表语保持一致,如:

What I am most interested in is American movies.

What I want is a large sum of money.

What I need are a great many books.

三、形式主语

为了避免头重脚轻,通常用it作形式主语,把主语从句放在后面作真正主语,常用句式有:

1.It + be + 形容词 + that-从句

It is necessary that everybody should have a healthy diet and exercise regularly.

2.It + be + 过去分词 + that-从句

It is said that she is going to study abroad after he graduates from Lanzhou University.

3.It + be + 名词 + that-从句

It is a pity that such an educated and qualified graduate cannot find a job.

4.其他含有it 作形式主义的句式:

It makes no difference who will go to Shanghai for the conference with me.

It remains to be seen whether she will join my research studio.

四、名词性从句的难点及区别

1.what引导主语从句时的理解:what在从句中要充当主语、宾语或表语;what经常译为“所…的东西”;what =the thing(s) that,如:

What made him proud was that his students had been admitted to key universities.(作主语)

What they want to do is to continue traveling abroad after retirement.(作宾语)

What she used to be is a secret to us all.(作表语)

2.wh+ever 与 no matter + wh-的用法。引导让步状语从句可以换用,引导主语从句只能用wh+ever,如:

Wherever you go and whatever you do,I’ll be right here waiting for you.

=No matter where you go and no matter what you do,I’ll be right here waiting for you.

Whatever you said at the meeting is very useful and valuable.

Whoever leaves the office last,please close the window.

=No matter who leaves the office last,please close the window.

篇4：It作形式主语的主语从句

_______(他突然想到)that he had an important conference to attend the next morning. (occur)

答案 It (suddenly) occurred to him.

考生们做本题时往往是记住了这是一个特殊的句型，实际上稍微分析可知，本句是一个含主语从句的复合句，其中it是形式主语，真正的主语是后面that引导的从句。大家看occur在这里的用法：sth occur to sb 意思是sth come into (one’s mind) ，即“(某人)突然想起……”。如：

An idea has occurred to me. 我已经有主意了。

It occurred to me that he had gone to the USA. 我突然想到他已经去美国了。

It has never occurred to me that he is a cheat. 我从没想到他是一个骗子。

与occur用法相似的动词有：seem, happen, appear, matter。

其句子结构一般是：

It+seem/appear/happen/occur/matter+that ...

It seems that he is ill. (= He seems to be ill.) 他好像病了。

It happens that I have had some experience in dealing with him. (= I happen to have had some experience in dealing with him.) 我碰巧在与他打交道方面有些经验。

It appears that they are in bad need of help. 他们看上去很需要帮助。

It suddenly occurred to me that all are not thieves. 我突然想起，并不是所有人都是小偷。

It doesn’t matter that he couldn’t come. 他不能来也没关系。

常用it作形式主语的主语从句有以下三种情形：

1. It is+adj.+that ...

It was clear that he was absent. 很明显他缺席了。

It seems unlikely (that) she will refuse the help. 她应该不会拒绝帮助。

It’s certain that William will do well in the exam. 威廉肯定能考得很好。

It’s possible that he won’t come. 他可能不会来了。

注意当表示建议，命令，要求等意义时，从句要用虚拟语气，谓语动词形式为(should) do。例如：

It is important that you (should) study hard. 对你来说，努力学习很重要。

It is necessary that you (should) obey the rules. 你必须要遵守规定。

试比较：

It isn’t surprising that he should have married her. 如果他与她结婚也没什么奇怪的。

It isn’t surprising that he married her. 他同她结了婚，这并不奇怪。

It is best that he (should) go. 他走了最好。

2. It+be+名词词组+that ...

It is a pity that we can’t go. 我们不能去真是太遗憾了。

It is common knowledge that the whale is not a fish. 鲸并不是鱼类是常识。

It is a pleasure that you have been here. 很高兴你能来这里。

It is a good idea that we’ll send for a doctor. 派人去请医生是个好主意。

注意表示惊奇、惋惜等感情色彩时，通常用虚拟语气。例如：

It’s no surprise that Brian should have won the game. 如果布莱恩赢得了比赛也不奇怪。

试比较：

It was a dictionary that John bought at the store. (强调句型) 约翰在商店买的是一本词典。

It is time that the children were in bed/went to bed. (定语从句) 到孩子们睡觉的时间了。

It is high time that such problems were solved. （定语从句）是该解决问题的时候了。

3. It+be+过去分词+that ...

“It is said/reported/announced/thought/believed/proved/known/expected that ...”句型可转换成相应的不定式形式。例如：

It is known that he will go abroad next month. (= He is known to go abroad next month.) 下个月他就要出国了。

It is said that he has published another book. (= He is said to have published another book.) 听说他出版了另一本书。

少数形容词作表语也可转换，例如：

It is likely that he will succeed. (= He is likely to succeed.) 他似乎要成功了。

It is certain that he will come. (= He is certain to come.) 他肯定会来。

如suggest, insist, order, demand等动词的过去分词作表语时，that从句需用虚拟语气，例如：

It is suggested that each student (should) sing a song in English. 大家提议每个学生都要唱一首英文歌。

It is demanded that everyone (should) hand in their exercises in time. 要求每个人都必须按时上交作业。

从上面三种句子结构中不难看出，由引导词that引导的主语从句一般用it作形式主语，而把that引导的真正的主语从句后置。

2)agree to + sth.(plan/suggestion等总括名词)

篇6：考研英语语法之主语从句

2016考研考生现在还处于基础准备阶段，对于考研英语来说，基础无非是单词和语法。现在，作者为大家献上考研英语语法集锦，希望能为大家带去复习上的帮助。

1.概述

在复合句中充当主语成分的句子叫作主语从句。具体形式为：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。

2.分类

⑴陈述句充当主语从句，连词为that(that没有实际含义，在从句中只起连接作用，不在从句中作任何语法成分)，从句为“that+陈述句”，that不能省略。

【例句】

That Chris Lee won the champion of Super Girl in arouse wide public concern.

李宇春赢得超女冠军这件事引起了社会的广泛关注。

⑵一般疑问句充当主语从句，连词为whether(whether“是否”的含义，在从句中只起连接作用，不在从句中作任何语法成分)，从句为“whether+陈述句语序”，whether不能省略。

【例句】

Whether this is true or not remains a mystery.

这是对是错还是个谜。

⑶特殊疑问句充当主语从句，连词为特殊疑问词(特殊疑问词都有自己的含义，在从句中作一定的语法成分)，从句为“特殊疑问词+陈述句语序”，特殊疑问词不能省略。

【例句】

例1 ――what

What caused the accident remains unknown.

是什么引起了这一事故仍然未知。

例2――where

Where my wife and I should enjoy our honeymoon is still unsettled.

我太太和我应该去哪享受我们的蜜月还没有最后决定。

例3 ――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4――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5――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6――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讨论。

3.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。

【例句】

例1 It is important that we all should attend the meeting.

我们都参加会议是重要的。

例2 It is strange that he should do that.

篇7：从句做主语

由连接代词或连接副词(或whether)引起的主语从句:

这类主语从句, 也可以放到句子后部去, 前面用it做形式上的主语.

when we shall have our sports meet is still a question.

it is still a question when we shall have our sports meet.

whether he will join us won’t make too much difference.

篇8：从句做主语

传统教育采用的是注入式教学法,现提倡的探究式学习的教学方法与传统的教学方法有着明显的不同。探究式学习是以学生为中心,注意激发学生的学习兴趣,让学生自主地探究事物之间的内在联系,然后由学生根据自己已有的知识和经验生成新的知识。教师的作用是负责课堂活动的组织和帮助学生解决遇到的疑难问题,促使学生得出新的结论,从而达到提高学生自我学习能力的目的。

语法教学的目的就是使学生通过学习基础的语法知识去掌握句型,进而用句型去进行听、说、读、写等实践活动,达到培养学生基本语言技能,从而培养学生的综合语言运用能力,最终能实现正确运用英语进行交际的目的。因此语法教学必定是英语教学中的一个重要组成部分。而目前很多教师在语法课采用的传统的语法演绎的教学方法,即先讲清概念,再呈现语法规则,后举例说明主要用法,最后要求练习和拓展。这种方法由理论到实践,直接、明了、简便,但容易导致以教师为中心,填鸭式教学。语法教学不是单纯的知识灌输,不应以讲解和传授为主,而让学生死记硬背语法规则,一味套用基本句型。因此,教师在教授新语法课时,必须多动脑筋,想方设法采取积极有效的语法授课方法。

《现代英语教程·一》Lesson Eight的中心语法是“主语从句”,而且是新授课。但在此之前的学习中,教材中有出现过这个语法现象,而且前一单元刚好学过名词性从句中的宾语从句和表语从句,因此对学生来说,不会感到陌生,理解上没有太大的问题。笔者根据此语法,在课堂教学中引导学生运用探究性学习的教学方法进行了一次尝试。

二、教学案例

主语从句教学观察与分析

1.背景

(1)上课时间:2010年4月10日

(2)上课地点:大专903班

(3)学生情况:全班50位学生,绝大多数来自农村。学生英语基础普遍很差,接受能力也差。

(4)知识背景:学生在前一单元刚好学过名词性从句中的宾语从句和表语从句,而且教材中也出现了此语法,因此对学生来说,不会感到陌生。

(5)教学目标:能辨认主语从句,能归纳总结主语从句的用法并能理解运用。

(6)预期目的:传统的语法教学中,教师往往给出语法规则,然后让学生操练,套用规则以达到巩固目的。这对学生来说,属于接受性学习。这样的教学方法,学生的主体性没有得到充分发挥,课堂气氛较沉闷,学生容易感到枯燥无味。因此,我想将探究性学习渗透在语法课堂教学中,创设情境,让学生发现语法规则,巩固规则,运用规则,从中发展学生的探究能力和创新能力。

2.设计意图、教学过程及分析。“探究性学习”强调以学生为主体,问题为中心,研究为手段,实践为途径,过程体验为重点,创新精神和实践能力培养为目的的一种学习方法。在本课设计时,我力求将上述特征体现在课堂教学中。本课较大的探究活动都安排了“小组合作“这一研究性学习的基本组织形式,研究性学习以过程体验为重点,使学生通过“观察—对比、讨论-归纳-巩固—运用”来真正掌握主语从句这一语法现象。

3.教学过程

(1)引入“发现规则“的探究活动

创设情境,激发学生的探究欲望。

Step1首先,让学生听一首大家都很熟悉的英文歌曲“what will be will be”

(分析:由于我以歌曲来引入语法教学,把枯燥无味的语法变成学生乐于接受的模式,这样可以提高学生学习此语法的兴趣。)

Step 2.Discovering structures.Give students some sentences and ask them to pay attention to the structure of these sentences. (板书并直观地划出句子的主语)

1You are students.

2To learn English well is not easy.

3Smoking is bad for your health.

4That we shall be late is certain.

5What she said is not yet known.

6Where the boy has gone is not known.

(分析:此举给学生一个直观的印象,让学生进一步认识主语从句的结构,加深印象,为下一步的学习作铺垫。整个过程比较顺畅自然,学生情绪愉快,达到了引入的目的,使学生自身处于一种主动认知的状态。)

Step 3.Reading and finding out the Subject Clause.

Ask the students to read the passage and find examples of subject clause in “How Life Began on the Earth”

在前面的一系列热身活动之后。让学生自己找出主语从句,让学生通过已输入的语法规则来观察运用,可加深学生对主语从句的印象,也为以后的运用打基础。

(2)布置任务,激励学生发现规则。

Step 4.Finding out the rules

1Let the students read the materials and have a discussion with their group members.

听到指令后,有的学生立即按课前分好的小组围在一起开始讨论。我在小组间作巡视,帮助引导基础比较差的学生发现规律。我注意到平时那些上课不爱开口的差生也能主动地问他们的组员为什么句子开头that,whether,who,what,which,when,where,how,why…气氛比较活跃,绝大部分学生能主动参与到讨论中。

2 At last let the students sum up the rules of subject clause.

此活动采用小组竞赛的形式来总结主语从句的规则及其用法,然后我作简单的点拨。

(分析:在这一过程中,由于我改变以往语法课的做法,把问题交给学生自己去讨论,探索,研究,发现并得出结论,这正是探究性学习的目的。通过探究,他们还得出了主语从句后面的谓语动词一般用单数的结论。)

(3)操练中“巩固规则”的探究活动。

Step 5.Practice

Do the exercises in the workbook.

Step 6.Competition

Give the students some uncompleted sentences and ask them to complete them with subject clause when necessary.

让学生从单纯的观察,发现到练习巩固。引入竞争机制能更大程度地调动学生的学习积极性,在练习中进一步熟悉,巩固和掌握。为下面的主语从句的运用:由句到一段话,由简单到复杂打下基础。

(4)运用中“巩固规则”的探究活动。Step 7.Play a game:Guessing who he/she is?

Ask the students to describe one of their classmates by using at least one subject clause and others guess who he/she is.

把话题转移到学生更为熟悉的同学身上,加大了难度。

(分析:从课后反应看,学生意犹未尽,多数学生体验到了成功的快乐,形成了主动积极的学习态度,基本达到了探究性学习的目的。)

Step 8 Self_assessment

Step 9 Summary and Homework

三、探究性学习教学学生调查和效果分析

为了了解本次探究性学习教学的效果,笔者做了一次简单的课后调查。90%的学生赞同教师常常使用探究性学习教学方法。因为他们觉得这种课堂气氛不沉闷,不是一味地听教师的讲解和死记硬背语法规则,对新的语法知识容易接受,记得牢固。75%的学生认为此课堂对他们的语法理解和口头书面表达均有帮助。在语法知识的学习心得方面,5%的学生能深入理解该语法形式,20%的学生能在操练阶段运用该语法形式,50%的学生在引入阶段能大概了解和初步掌握该语法的形式和意义。在巩固规则的练习方面,95%的学生认为很重要,主要是因为不做练习,就会忘记所学的语法规则。从以述表明:探究性学习教学得到了学生的肯定,起到了提高学生英语语法学习的兴趣和信心的作用。

四、教学反思

1.我将本课与平时的传统教法相比,发现运用探究式的教学方法更能充分发挥学生的主体性,学生思维的广度、深度、密度更大,更易形成良好的学习方法、策略。本课的大部分时间是学生活动,“以学生为主体”的教学理念得到了发挥。小组讨论学习的形式,又增强了学生的合作意识。学生从发现规则的喜悦,到巩固规则,运用规则的兴奋,学生体验到了探究性学习的快乐。而这种体验,又促进了学生学习英语的积极性。

2.教师在探究活动中的主导作用非常重要。体现在对教材的钻研、教学过程的设计、情感的激励、探究学习的氛围的营造等方面。因此,对学生的积极参与要给予肯定,并及时地进行总结评价。

3.让学生保持学习的热情和兴趣体验使用语言的成功感很重要。宽松、和谐的气氛容易激活学习的思维,他们能比较快的理解语法项目且留下较深的印象。

4.机械性操练和及时点拨是关键。在开始实施时,一定要给予学生足够的时间对语法的形式和意义进行讨论归纳,也要让他们在句子中反复使用和体会该语法功能。

篇9：英语主语从句用法剖析

【关键词】连接词主语从句形式主语难点区别

众所周知，引导名词性从句的连接词通常有三类，他们用法各不相同，现解释如下：连接词that，没有词义；不作句子成分；但在主语从句中不能省略；连接词if ＼whether，词义“是否”；不作句子成分，不能省略；在主语从句中只用whether；连接代词what，whatever，which，whichever，who，whoever，whom，whomever，whose 以及连接副词when，whenever，where，wherever，how，however，why，有词义；在主语从句中作主语、宾语、表语和状语；不能省略。

一、主语从句概述

在主从复合句中充当主语的一个句子就叫主语从句，例如：That the earth goes round the sun is well-known to everybody.

Whether she will come to help us has not been known yet.

When we will go to Beijing for visa to America is still a secret.

二、主语从句中的主谓一致

当主语从句作一个主从复合句的主语时，主句的谓语动词通常用单数，但what 引导的主语从句中谓语动词是need，want，require等的时候，主句谓语动词和表语保持一致，如：

What I am most interested in is American movies.

What I want is a large sum of money.

What I need are a great many books.

三、形式主语

为了避免头重脚轻，通常用it作形式主语，把主语从句放在后面作真正主语，常用句式有：

1.It + be + 形容词 + that-从句
