主语从句详解及练习-附答案

语法要点剖析 一、名词性从句 主语从句、表语从句、宾语从句、同位语从句，在整个句子中所起的作用，相当于一个名词。因此，这四种从句通称为名词性从句。 引导名词性从句的连接词可分为三类： 连接词：that, whether, if （不充当从句的任何成分） 连接代词：what, whatever, who, whoever, whom, whose, which. 连接副词：when, where, how, why 1. 主语从句 作句子主语的从句叫主语从句。主语从句通常由从属连词that，whether，if 和连接代词what，who，which，whatever，whoever以及连接副词how，when，where，why等词引导。that在句中无词义，只起连接作用；连接代词和连接副 词在句中既保留自己的疑问含义、又起连接作用，在从句中充当从句的成分。例如： What he wants to tell us is not clear. 他要跟我们说什么，还不清楚。 It is known to us how he became a writer. 我们都知道他是如何成为一名 作家的。 Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行，还没有宣布。 有时为避免句子头重脚轻，常用形式主语it代替主语从句作形式主语放于句首，而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下： （1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句 （3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句 另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有： It is necessary (important, natural, strange, etc.) that … It is a pity (a shame, no wonder, etc.) that… It is suggested (requested, proposed, desired, etc.) that… 2. 宾语从句 名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样，在句中可以作谓语动词或介词及非谓语动词的宾语。 1. 由连接词that引导的宾语从句 由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。例如：He has told me that he will go to Shanghai tomorrow.他已经告诉我他明天要去 上海。 We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好，别人什么都不好。

必修三Unit4主语从句

必修三Unit4主语从句(Subject Clause) ?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。 ?位置： 1.通常放在主句谓语动词之前 That he will succeed is certain. Who will be our monitor hasn't been decided yet. Whether he will join us won't make difference. How the book will sell depends on its author. What caused the accident remains unknown. 2.由形式主语it代替，而本身放在句子末尾。 It doesn’t matter whether he is wrong or not. ?辨别下列从句的类别(1-6)：主从；宾从；表从；主从；宾从；主从 ?主语从句的连接词 引导主语从句的连接词可分为三类：连接词：that, whether / if；连接代词：what, which who, whom, whose, whatever, whoever, whichever等；连接副词：when, where, how, why, whenever, wherever等。 ●that:1.无词义；2.在主语从句中不作成分；3.一般不能省略（尤其在句首时） That he will come and help us is certain. That he is the best student in the class is obvious. ●Whether / if: 1.有词义：“是否”；2.在主语从句中不作成分；3. whether引导的主语从句可 放句首、句末；4. If引导的主语从句不能位于句首。 Whether we will succeed is still a question. If we will succeed is still a question. (×) It is not known whether / if he will come. what, whatever, who, whoever, whose, which, whichever when, where，why, how等。 1.有词义； 2.在主语从句中作成分。 What he is has nothing to do with you. Whose ticket this is has not been found out. When the test will be given is not yet decided. Whatever you did is right. ?如何选择连接代词和连接副词 在主语从句中，连接词的选择要看这个从句的句子结构，假如根据意思判断为缺少主语，宾语，表语等时应该考虑who, whoever, which, whichever, what, whatever, whom, whomever；如果缺少定语则想到whose, which；如果缺少状语则应该选择how, where, when, why等。因此要想做好题目首先得了解句子成分。 What I can’t understand is why he has changed his mind. （缺少understand的宾语，意为“…的事”） Whoever breaks the law will be punished.（缺少breaks的主语，意为“无论谁”） ?主语从句后置！ 为了避免主语冗长，句子头重脚轻，主语从句作主语时通常用it作形式主语，主语从句放在后面作真正的主语。 That he finished writing the composition in such a short time surprised us. =It surprised us that he finished writing the composition in such a short time. Whether he will come or not doe sn’t matter. =It doesn’t matter whether he will come or not. Who will do that job is not yet decided. =It is not yet decided who will do that job. ?用it作形式主语的that从句有以下搭配关系： 1. It + be +形容词+ that从句 It is necessary / important / obvious / certain / natural…that… It is necessary that the problem should be discussed at once.

高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather.

It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B.

C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day.

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。
