高中英语主语从句
高中英语主语从句主语从句，在英语语法中，是一个句子作为主语，它可以是陈述句、疑问句或者是特殊疑问句。
这种从句在高考英语中占据了重要的地位，因此，理解和掌握主语从句的用法对于高中生来说至关重要。
我们要理解什么是主语从句。
主语从句就是一个句子在复合句中充当主语，例如：What he said is not true.在这个句子中，“What he said”就是一个主语从句。
主语从句有三种类型：陈述句、疑问句和特殊疑问句。
陈述句作为主语从句时，通常以that引导，例如：That he will come to the party is certain.疑问句作为主语从句时，通常以whether或what引导，例如：Whether he can come is still a question.特殊疑问句作为主语从句时，通常以who、what、which等引导，例如：Who will come is not clear.在理解了主语从句的基本概念和类型之后，我们还需要掌握如何正确使用主语从句。
使用主语从句时，需要注意以下几点：主语从句的引导词要使用正确；主语从句的时态要和主句保持一致；主语从句的语序要使用陈述句语序。
除了正确使用主语从句，我们还需要理解主语从句的省略情况。
在某些情况下，主语从句可以省略掉that，例如：It is certn (that) he will come.这种情况下，it是形式主语，真正的主语是that he will come。

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。

Does _______ matter if he can't finish the job on time?A. thisB. thatC. heD. it2. It worried her a bit _______ her hair was turning grey.A. whichB. thatC. ifD. for3. _______ is a fact that English is being accepted as an international language.A. ThereB. ThisC. ThatD. It二、学习主语从句应该注意的几个问题1)引导词that与whatwhat既有引导主语从句的作用,同时又在从句中作句子成分(主语、宾语、表语等).这时what相当于all that/everything that...,常译成"所……的(东西、事情、话等.)";而that只起连接作用,本身无实际意义,在从句中也不担当任何句子成分.但that引导的主语从句放在句首时,不能省略that.例如:What is done can't be undone. (谚语)已成定局,无可挽回.What we can't get seems better than what we have.我们得不到的东西似乎比已得到的要好.That we should work out a plan to deal with the present serious situation is important.我们应该制定一项计划来应付目前严峻的形势,这一点非常重要.That a new teacher will come to teach us geography is true.一位新老师将来教我们地理,这是真的.[巩固练习]4. _______ what they told me really true?A. HasB. IsC. DoesD. Have5. It matters little _______ a man dies, but _______ matters much is _______ he lives.A. how; what; howB. how; it; howC. why; it; whyD. that; what; that6. _______ she couldn't understand was _______ fewer and fewer students showed interest in her lessons.A. What; whyB. That; whatC. What; becauseD. Why; that7. It is pretty well understood _______ controls the flow of carbon dioxide in and out the atmosphere today.A. thatB. whenC. whatD. how8. _______ fashion differs from country to country may reflect the cultural differences from one aspect.A. WhatB. ThatC. ThisD. Which9. -What made her parents so angry?- _______ she had failed in the examination.A. AsB. BecauseC. SinceD. That2)引导词if和whetherif和whether引导动词后的宾语从句时一般可通用,但介词后的宾语从句、主语从句(放在句首时)、表语从句常由whether引导.例如:Whether she will go home or not is unknown.她是否回家还不得而知.Whether we shall raise ducks or geese remains to be decided.我们是养鸭还是养鹅仍没决定.=It remains to be decided whether/if we shall raise ducks or geese.但我们不能说If we shall raise ducks or geese remains to be decided.[巩固练习]10. _______ we'll go camping tomorrow depends on the weather.A. IfB. WhetherC. ThatD. Where3)其它引导词连接代词who, which, whom, whose有各自的意义,起连接作用,并在从句中充当语、宾语、表语、定语等;连接副词when,where, why, how等有各自的意义,起连接作用,并在从句中充当状语.[巩固练习]11. -Do you remember _______ he came?-Yes, I do. He came by car.A. howB. whenC. thatD. if12. It was a matter of _______ would take the position.A. whoB. whoseC. whomD. whomever13. -I drove to Zhuhai for the air show last week.-Is that _______ you had a few days off?A. whyB. whenC. whatD. where14. I read about it in some book or other, does it matter _______ it was?A. whereB. whatC. howD. which三、语气在It is necessary / natural / important / strange...+ that-clause这类句型里,that所引导的主语从句中谓语动词用"should +原形",表虚似语气.例如:It is necessary that the problem should be settled at once.这个问题必须马上解决.It's strange that he should have gone away without telling us.他竟然没向我们说一声就走了,真是奇怪.[巩固练习]15. It is necessary that a college student _______ at least a foreign language.A. mastersB. should masterC. masteredD. will master四、以it作形式主语的主语从句与强调句型的区别"It be + adj./n. + that-clause"与强调句型均有It be...that...之类的语言标志,但不同的是:①前者中的that从句是主语从句.若删掉其中的It be和that,则剩余部分不论结构还是语意都不能成为一个句子;但若将后者中的It be和that去掉,则剩余部分的结构和语意仍能构成一个完整的句子.②强调句型译为汉语时可加上"正是……"或"就是……"之类的字眼,而主语从句则不可以.请比较下面两个句子:It is surprising that Mary should have won first place.令人惊奇的是玛莉竟然获得了第一名.It is Mary that has won first place.正是玛莉得了第一名.第一句话中的It是形式主语,that引导的是主语从句.句中的It is和that无法删除,一旦删除句子就不成立.第二句是强调句型,其中的It is和that可以去掉,因为没有It is和that句子仍然很通顺.Key: 1-5 DBDBA 6-10 ACBDB 11-15 AAADB(文/李来生《英语通》高二版2004年第2期；版权归英语辅导报社所有，独家网络合作伙伴新浪教育，未经许可，不得以任何形式进行转载。

高中英语知识点归纳主语从句的用法
高中英语知识点归纳主语从句的用法主语从句是英语语法中的一个重要知识点。
它用于修饰主句的主语，并在句子中起到名称、代词或名词性从句的作用。
通过使用主语从句，可以使句子结构更加丰富多样，表达更加具体清晰。
下面是对主语从句的用法进行归纳总结。
1. 引导主语从句的连接词：主语从句通常由从属连词引导，常用的引导词有：- That：常用于陈述句中，作为连接词引导主语从句。
例如：“That he is a talented singer is widely known.”- Whether/if：用于疑问句或选择句中，引导主语从句。
例如：“Whether he will come or not is still uncertain.”- Who/whom/whose：用于引导讨论人的主语从句。

例如：“Why he left in such a hurry is still a mystery.”3. 动词形式与主语从句：主语从句的谓语动词形式与从句中的主语保持一致，即采用单数或复数形式。
例如：“What I want is a peaceful life.”4. 主语从句的时态：主语从句的时态通常与主句时态保持一致。
例如：“That she has passed the exam is a great relief to her parents.”5. 特殊情况下的主语从句：在某些特殊情况下，主语从句中的谓语动词应为不定式形式。
如：- It + be + 原形动词 + that从句：例如“It is important to study hard.”- There + be + 名词 + that从句：例如“There is no doubt that he is telling the truth.”通过对主语从句的学习与理解，可以更好地运用它，丰富句子结构，使语言表达更加准确、流畅。
