三大类从句的引导词
主语从句的引导词和句型变换
主语从句的引导词和句型变换主语从句是指在句子中充当主语成分的从句。
引导主语从句的词有很多种,包括连接代词和连接副词等。
在英语中,主语从句的引导词有that, whether/if, who, whom, whose, which, what等等。
而为了表达的多样性和语言的灵活运用,同一个主语从句可以通过句型变换来转换为其他类型的句子。
一、主语从句的引导词1. that:常用于陈述句和命令句中,引导主语从句,在从句中作为连接词,不充当任何成分。
- That he is a hardworking student is well known to all. (他是一个勤奋的学生这个事情众所周知)2. whether/if:常用于疑问句和选择句中,引导主语从句,是否表示做出选择或询问。
- Whether he will come to the party is still unknown. (他是否会来参加派对还不得而知)3. who, whom, whose:常用于人作主语的句子中。
- Who will be the winner of the competition is yet to be announced. (比赛的获胜者还未宣布)4. which:常用于物作主语的句子中。
- Which dress to wear tonight is still a dilemma for me. (今晚穿什么衣服对我来说还是个问题)5. what:常用于事物作主语的句子中。
- What we should do next is to find a solution. (我们下一步应该做的是找到一个解决办法)二、主语从句的句型变换1. 主语从句变为it作形式主语原句:That he is a hardworking student is well known to all.改写:It is well known to all that he is a hardworking student.2. 主语从句变为it作形式宾语原句:Whether he will come to the party is still unknown.改写:It is still unknown whether he will come to the party.3. 主语从句变为what/which + to be动词的句型原句:Who will be the winner of the competition is yet to be announced.改写:What/which to be the winner of the competition is yet to be announced.4. 主语从句变为wh-疑问词 + 不定式结构的句型原句:Which dress to wear tonight is still a dilemma for me.改写:What dress to wear tonight is still a dilemma for me.5. 主语从句变为wh-疑问词 + 不定式短语的句型原句:What we should do next is to find a solution.改写:What to do next is to find a solution.总结:主语从句的引导词和句型变换可以帮助我们表达意思的多样性和语言的灵活运用。
三大从句
从句从句按其在主句中的句法功能可分为三类:即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。
引导从句的词称作关联句。
一、名词性从句引导这些名词性从句的关联词包括:从属连词:that, if, whether;连接代词:who,whoever,whom,whomever,which,whichever,what,whatever,wh ose;连接副词where, when, why, how。
其中, 从属连词只起连接作用, 在从句中不充当任何句法成分,而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.不可省略的连词:1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.We heard the news that our team had won.比较:whether与if 均为"是否"的意思。
但在下列情况下,whether 不能被if 取代:1. whether引导主语从句并在句首2. 引导表语从句3. whether从句作介词宾语4. 从句后有"or not"Whether he will come is not clear.The fact is that he didn't go to the dinner party.I don't know if he will attend the meeting.1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. That-从句作主语通常用it作先行词,而将that-从句置于句末,例如:It is quite clear that the whole project is doomed to failure.很清楚,整个计划注定要失败。

从句概述
• 从句只能做主句的某一部分,依附于主句 而存在,不能独立。
• 从句也具有句子的特征,即有自己的主 谓结构;而且带有引导词。
• 根据从句在句中的作用,可分为名词性 从句、形容词性(定语)从句和副词性 (状语)从句三类。
一、名词性从句
名词性从句包括主语从句、宾语从句、表语从句和同位语从句。其关 联词有连词that, if, whether;连接代词what, who, which和连接副 词when, where, why, how等。

连接词的用法 (三)
3.Who, whom, whose, what, which

④ It +v. (seems / happened, etc. )+that-clause It seems that Alice is not coming to the party at all. It happened that I was out that day.

定义:如果一个句子在复合句中充当一个主语,那么这个句子就是主语从句• 第一部分:常规主语从句,即句子在复合句中充当一个主语(1)That he finished writing the composition in such a short time surprised me. (2)Whether we will go for an out ing tomorrow rema ins unknown.(3)Who will be our monitor has't been decided yet.(4)Whom we must study for is a question of great importanee.(5)What caused the accide nt rema ins unknown.(6)Whatever you did is right.(7)Whose watch was lost is unknown.(8)What we need is time.(9)What we need are good doctors.小结:(1)引导主语从句连词有that,whether,who,what,whatever 等(2)连词位于句首不能省略(3)主语从句大多数情况下视为单三,但也有例外,如例9第二部分:为了防止句子头重脚轻,通常把形式主语it放在主语位置,真正主语搁置于句末(1)It is certain that he will win the match.(2)It is true that he has madea very important discovery in chemistry.(3)It is very likely that they will hold a meeting.(4)It is strange that he should do that.(5)It is important that we all should attend the meeting.(6)It is strange that the man should have stuck to his silly ideas.(7)It is a pity that we won't be able to go to the south to spend our vacati on. (8)It is still a mystery what caused the accident.(9)It is said that he has gone to Taiwan.(=He is said to have gone toTaiwa n)(10)It is known to all that the gun powder was first inven ted by theChin ese.(11)It is suggested that the work should be done with great care.(12)It seems that he has seen the film.(二He seemsto have seen the film)(13)It happenedthat the two cheats were there. (=The two cheats happened to be there)小结:(1)以that引出的主语从句,常以形式主语it引导.It is + 形容词/名词/某些动词ed + that 从句.(2)在有些that从句中要用虚拟语气(should+do/should+have done)例句4,5,6,11.名词性从句在句子中起名词作用的句子叫名词从句(Noun Clauses )。
名词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、介词宾语等,因此根据它在句中不同的语法功能,名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。
一、引导名词性从句的连接词引导名词性从句的连接词可分为三类:连词:that (无任何词意)whether, if 均表示“是否”表明从句内容的不确定性)as if ,as though (均表示“好像”,“似乎”)以上在从句中均不充当任何成分连接代词:what, whatever, who, whoever, whom,whose, which. whichever, whomever连接副词:when, where, how, why不可省略的连词:1. 介词后的连词2. 引导主语从句和同位语从句的连词不可省略。
That she was chosen made us very happy.We heard the news that our team had won.比较:whether 与if 均为"是否"的意思。
但在下列情况下,whether 不能被if 取 代:1. whether 引导主语从句并在句首2. 引导表语从句3. whether 从句作介词宾语4. 从句后有 "or not"Whether he will come is not clear.大部分连接词引导的主语从句都可以置于句末,用 it 充当形式主语。
It is not important who will go.It is still unknown which team will win the match.二 . 主语从句1. 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.Who will win the match is still unknown. 知。
It is known to us how he became a writer.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。
他要跟我们说什么,还不清楚 谁能赢得这场比赛还不得而我们都知道他是如何成为一2. 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It is believed that 25 years after construction, the building was dismantled and moved timber by timber to the South Bank of the Thames, where a reconstruction of the theatre now stands.据信经过25 年的建设后, 该建筑物将被拆处. 并且该建筑物的一砖一石将被移到泰唔士河的南岸. 重建的戏剧院现在正座落于此。
It is thought the cost of this lost labour is around £ 1 billio n (10 billi on yua n)to businesses and the economy.大家一直认为这次对贸易和经济失去劳动力的损失的费用应该在10 亿英镑(人民币100 亿元)It is not known how many of the 59 million words Mr Shea has remembered but he has certainly made history with his eccentric hobby.在590 万的词汇中到底记住了多少不得为知, 但是她却以这样的怪癖创造了历史。
4)It + 不及物动词+ that 从句3. 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 n ecessary (importa nt, n atural, stra nge, etc.) that …It is a pity (a shame, no won der, etc.) that •…It is suggested (requested, proposed, desired, etc.) th at …4. It 作形式主语和it 引导强调句的比较It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。
而it 引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。
被强调部分指人是也可用who/whom例如:It is a pity that you didn 't go to see the film. It doesn't interest me whether you succeed or not.It is in the morning that the murder took place. It is John that broke the window.5. What 与that 在引导主语从句时的区别What 引导主语从句时在句时在从句中充当句子成分,如主语.宾语.表语,而that 则不然。
(1) What you said yesterday is right. (2) That she is still aliveis a consolation.名词性从句--- 宾语从句; 表语从句(2009-03-18 22:15:32)转载三、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. 作动词的宾语:1) . 由that 引导的宾语从句( that 通常可以省略, 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。
