引导名词性从句的连接词可分为三类

引导名词性从句的连接词可分为三类
引导名词性从句的连接词可分为三类

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, whichever,whomever

连接副词:when, where, how, why,how many,how much,how oft en

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。

主语从句(在复合句中,作句子的从句叫主语从句。引导主语从句的词有从属连词that,whether以及连接代词who,what,which,whoever,whatever,whichever呵连接副词when,where,why,how等。)

it作形式主语的从句

1. It is +adj. / n.+从句例如:

It is a pity/shame that…遗憾的是…

2. It +vi.+从句例如:

It seems that…似乎…

It happened that…碰巧…

3. It+be+过去分词+从句例如:

It said that…据说…

注意:“it is necessary / natural / important / stange…+that从句”这种句型里,that所引导的主语从句中谓语动词用“should+原形”,表虚拟语气。

引导词that与what

That引导主语从句是,只起连接作用,本身无实际意义,在从句中不担当任何句子成分,但不能省略;what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w hat相当于all that/everying that…

例如:

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。

引导词if和whether

引导主语从句时只能用whether而不能用if

其他引导词

连接代词who,which,whom,whose有各自的意义,起连接作用,并在从句中充当主语、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。

宾语从句

引导词

1. 由连词that引导的宾语从句

连词that引导宾语从句时,that在句子中不担任任何成分,在口语或非正式文体中常被省略。

注意:

①如果及物动词后面有两个(或两个以上)并列的宾语从句时,只

有第一个连词that可以省略。

②在demand,order,suggest,insist。Desire。request。comm

and等表示要求、命令、建议、决定等意思的动词后,宾语从句常用“(should)+动词原形”

③当宾语从句后接宾语补足语事,常用it做形式宾语,而将宾语从

句后置。

2. 由连词whether或if引导的宾语从句

Whether或if引导宾语从句是仍保留“是否”的含义,从句仍保持陈述语序,whether或if在从句中不担当成分。

3. 由连接代词或连接副词引导的宾语从句

例如:Could you please tell me how you use the new the pa nel?

(你能告诉我怎么用这个心的操作盘吗?)

时态

在宾语从句中,从句的时态常常受到主语从句时态的影响,因而在使用时要注意主从句两部分的时态保持一致。一般要遵循以下原则:

1. 主句如果是现在或将来时态,从句可以任何所需要的时态

2. 主句如果是过去时态,从句谓语动词一般要用过去时态的某种形

式。

注意:当从句描述的是客观事实或客观真理是,从句要用一般现在时。语序

通常情况下宾语从句的语序用陈述句语序,即“主语+谓语”

表语从句

引导词

1. 连词that引导的表语从句

That仅起连接作用,无意义,在句中不作任何成分,通常不能省略。这种从句往往对主句主语的内容起进一步解释的作用。其基本结构为“主语+系动词+that从句”

2. 连词whether引导的表语从句

连词whether起连接作用,意为“是否”,在句中也不作任何成分。

3.连接代词what,which,who,whom,whose引导的表语从句连接代语what,which,who,whom,whose除在句子中起连接作用外,还可以在从句中充当主语、宾语、表语、定语,且各有各的词义。

4.连接副when,where,how,why引导的表语从句

连接副词when,where,how,why除在句中起连接作用外,在从句中还充当时间、地点、方式、原因状语,本身具有词义。

5. 其他连词because,as if/ as though引导的表语从句

because引导的表语从句通常只用于“This/That/ It is /was beca use…’’结构中:as if/ as though引导的表语从句如果与事实相符,从句用陈述语气:如果从句的内容与事实不相符,则用虚拟语气。几点注意事项

1.表语从句一定要用陈述句语序。

2.If与whether意思均为“是否”,但引导表语句时,只能有wh ether,不能用if.

3.当主语是reason时,其后的表语从句要用that引导。

4.除了系动词be之外,其他系动词,如feel,seem,appear,look,r emain等之后也可以跟表语从句。

what引导名词性从句五种用法

what引导名词性从句的五种用法 一、用法归纳 1. 表示“……的东西或事情”: They’ve done what they can to help her. 他们已经尽力帮助了她。 He saves what he earns. 他赚多少,积蓄多少。 What Mary is is the secretary. 玛丽的职务是秘书。 2. 表示“……的人或的样子”: He is no longer what he was. 他已经不是以前的那个样子。 He is what is generally called a traitor. 他就是人们通常所说的叛徒。 Who is it that has made Fred what he is now? 是谁把弗雷德培养成现在这个样子的? 3. 表示“……的数量或数目”: Our income is now double what it was ten years ago. 我们现在的收入是10年前的两倍。 The number of the students in our school is ten times what it was before liberation. 现在我校学生的数量是解放前的10倍。 4. 表示“……的时间”: After what seemed like hours he came out with a bitter smile. 似乎过了几个小时他才苦笑着出来。 The young girl was too frightened to speak, standing there for what seemed like hours. 小女孩吓得不敢说话,在那儿站了几个小时。 5. 表示“……的地方”: This is what they call Salt Lake City. 这就是他们称为盐湖城的地方。 In 1492, Columbus reached what is now called America. 1492年哥伦布到达了现在所称的美洲大陆。 二、用法说明 (1) 这样用的what相当于“先行词+关系代词”,所以其前不能有先行词: 你喜欢什么就拿什么吧。 正:You can have what you like. / You can have everything (that) you like. 误:You can have everything what you like. (2) 有时what 可用作限定词,其后修饰一个名词: I gave him what books I had. 我把我所有的书都给他了。 He gave me what money he had about him. 他把身边带有的钱全给了我。 (3) What 后的名词可以是复数名词或不可数名词,但通常不能是单数可数名词: 误:I gave him what book I had.

what引导名词性从句

what引导名词性从句 what引导主语从句 1. What David used to say was always new and worth hearing and all his pupils loved him. 2. What makes the book so special is the name of the writer. 3. What impresses me about his painting is the colors he uses. 4. What you said at the meeting describes a bright future for the company. 5. What is important is that we let others know we care about them. 解析考查主语从句的引导词。根据句子结构可知,系动词is前的句子缺少主语,表示“重要的事情”要用what。 6. What some people regard as a drawback is seen as a plus by many others. 意思:一些人看作是缺点的东西却被许多其他的人看作优点. 7. What struck me most in the movie was the father's deep love for his son. 解析本题考查主语从句。句意:这部电影让我最感动的地方就是父亲对儿子的深深的爱。主句谓语动词was之前为主语从句,其中缺少主语指事物,故使用代词what。

What引导宾语从句 1.I’m interested in what you’ve sai d. (介词后的宾语从句) 2. Tina is much more confident behind the wheel than what she was when she started. (介词后的宾语从句) 3. If you swim in a river or lake, be sure to investigate what is below the water surface. Often there are rocks or branches hidden in the water. 解析如果你在河里或湖里游泳的话,务必调查清楚水面之下有什么。水中经常隐藏着石头或树枝。根据后面rocks and branches可知,此处要用what来引导。 4. Reading her biography,I was lost in admiration for what Doris Lessing had achieved in literature. 解析句意:读了多丽丝·莱辛的传记,我很钦佩她在文学上获得的成就。考查名词性从句。考查宾语从句的连接词。在介词for后的是宾语从句,从句中缺少achieve的宾语,故用what引导。(介词后的宾语从句) 5. Pick yourself up.Courage is doing what you're afraid to do. 解析考查名词性从句。句意:跌倒后再站起来。勇气是做你不敢做的事情。这里含有一个宾语从句,引导词在从句中作do的宾语,所以用what。 6. It is difficult for us to imagine what life was like for slaves in the ancient world.

名词性从句的引导词有哪些用法怎样

名词性从句的引导词引导词是否在名词性从句中充当 成分的情况 连接代词:what, which, who, whom, whose 连接副词:when, where, why, how what, which 在从句中作主语、宾语、表语或定语;who 在从句中作主语、表语;whom 在从句中作宾语;whose 在从句中作定语;when, where, why, how 在从句中分别作时间状语、地点状语、原因状语、方式状语连词that 否 连词whether, if 否 名词性从句的引导词在高考中的基本用法详见下面的 总结: 1.引导特殊疑问句的疑问词在转为引导名词性从句时, 即成为连接代词(主要包括what, which, who, whom, whose)或者连接副词(主要包括when, where, why, how).注意体会如下例句:Choose which you like best. 选你最喜欢的.// Who has taken away my bag is unknown. 谁拿走了我的包还不知道.// Have you decided whom you are to nominate as your candidate? 你们是否已经决定提名谁做候选人了?// He asked when Mr. Gilbert would be allowed to go

home. 他问什么时候可以允许

吉尔伯特先生回家.// Where we can look up his address is still a problem. 我们在哪儿可以查到他的地址还是个难题.// Why he did that wasn't quite clear. 他为什么做那件事还不十分清楚.// How they will solve the serious problem has not been decided. 他们将怎样解决这个严重问题还没有决定. 以下两种特殊情况要给予特别关注: (1) what 作连接代词引导的名词性从句既可以表示一个 问“什么……?”的问题, 也可以表示相当于“名词/代词+关系代词引导的定语从句”结构的意思, 这种特殊用法在语法上被称作“关系代词型的what”, 注意体会如下例句:He is not what (=the person that) he was a few years ago. 他不是几年前的他了.// This is what (=the place that) they call Salt Lake City. 这就是他们称作盐湖城的地方.// What (=the place that) is now the North Sahara Desert was once a civilized world. 现在的北部撒哈拉沙漠曾是一个文明世界.// Our income is now double what (=the income that) it was ten years ago. 我们现在的收入是十年前的两倍.// The color of the flower is different from what (=the color that) it was in the morning. 花朵(现在的)颜色与它早上的颜色不同. (2) 带'ever 后缀的疑问词除引导让步状语从句之外, 还 可以引导名词性从句(“no matter+疑问词”的结构只能引导让步状语从句, 不可以引导名词性从句), 注意体会以下例

(完整版)从句连接词判断方法

从句就相当于一个形容词, 而且从句前面一定有一个先行词, 从句必有缺少的成分(主语,宾语,状语)。 如果先行词在从句做主语,则用which / that / who(人) 如果先行词在从句做宾语,则用which/ that/ who(人) /whom(人)或者不填引导词 如果先行词在从句做状语,时间用when,地点用where。 定语从句及相关术语: 1.定语从句:定语从句是由关系代词或关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,相当于形容词,所以又称为形容词性从句,一般紧跟在它所修饰的先行词后面。 2.关系词:引导定语从句的关联词称为关系词,关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等;关系副词有where, when, why等。关系词常有3个作用:1,引导定语从句。2,代替先行词。3,在定语从句中担当一个成分。 注:关系代词有主语.宾语之分。一般whom作为宾语。 4.定语:定语用来限定、修饰名词或代词的,是对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用‘……的’表示。主要由形容词担任。此外,名词,代词,数词,分词,副词,不定式以及介词短语也可以来担任,也可以由一个句子来担任.单词作定语时通常放在它所修饰的词之前,作前置定语。短语和从句作定语时则放在所修饰的词之后,作后置定语。 先行词:被限制或修饰的主句的主语。 (一)限定性定语从句 一、关系代词(在句中作主语、宾语或定语) 1. that既可代表事物也可代表人,which代表事物;它们在从句中作主语或宾语,that在从句中作宾语时常可省略关系词,which在从句中作宾语也可以省略。[eg:this is the book (which)you want。]而且,如果which在从句中作“不及物动词+介词”的介词的宾语,注意介词不要丢掉,而且介词总是放在关系代词which的前边,但有的则放在它原来的位置 2. which作宾语时,根据先行词与定语从句之间的语义关系,先行词与which之间的介词不能丢 3. 代表物时多用which,但在带有下列词的句子中用that而不用which,这些词包括当先行词是anything, everything, nothing , none等不定代词时,或者是由every, any, all, some, no, little, few, much等修饰时等,这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that 4. who和whom引导的从句用来修饰人,分别作从句中的主语和宾语,whom作宾语时,要注意它可以作动词的宾语也可以作介词的宾语 5. whose是关系代词,修饰名词作定语,相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与of which 调换,表达的意思一样。 二、关系副词(在句中作状语) 关系副词=介词+关系代词 why=for which where=in/ at/ on/ ... which (介词同先行词搭配)

名词性从句----绝对经典系列

名词性从句Noun Clauses 一.基础定义和连接词 1. 名词性从句:就是在句子中起名词作用的从句。 2. 名词性从句包括4种从句:主语从句、宾语从句、表语从句、同位语从句。从高考的考查的实际情况来看,名词性从句考得最多的是宾语从句,其次是主语从句,再次是表语从句,而同位语从句则很少考查。 [判断]以下从句类型: 1) The truth is that I have been there.( ) 2) The fact that she was late surprised us.( ) 3) That he will come is certa in.( ) 4) I know that he will come.( ) 3. 名词性从句的连接词有: 从属连词(不做成分):that (无意义)‘whether, if(是否)…. 连接代词(在从句中做主,宾,表,定):what, who, whom, whose, which, whatever, whoever, whichever 连接副词(在从句中做状语):whe n, where, how , why 二.名词性从句位置和特点主语从句:1.可直接放在句首。 2. 主语较长时通常用It作形式主语,而将主语从句放在后面。 1) . ___ he knows Japaneses known to all. 2) . _____ surprised me was to see him here . 3) ________ he is comingdoesn' t matter much. 4) It remains a secret _____ they climbed up the mountain. 宾语从句:可做动词,介词和部分(表情感态度的)形容词词的宾语。 I want to know whe n we will start. Everyth ing depe nds on whether we have eno ugh time. I ' imfraid (that) I have made a mistake. 注意:如果宾语从句后面有宾补要使用it作形式宾语而将从句放到宾补后面。 常见的可以接it形式宾语的动词有:make, think, find, feel, consider等 He made it clear that he was determined to resign . I thought it strange that he didn ' t call me. 表语从句: 1. 位于系动词动词之后。常见此类系动词有be, look , seem,即pear等 It seems that she has known the truth. It looks as if it is going to rain. This school is no Ion ger what it was before. 2. 主语是reason时,表语从句常用that引导,不用because引导。

名词性从句的连接词选用

名词性从句的连接词选用 名词性从句包括主语从句,表语从句,宾语从句和同位语从句引导同位语从句的词通有连词that,whether,连接副词how,when,where 等。(注:if 不能引导同位语从句。)。在各种考试中,其最主要的考查内容为连接词的选用。名词性从句的连接词可细分为以下四种:(1)以that来引导从句;(2)以whether/if引导从句;(3)以特殊疑问词引导从句;(4)以关系代词/副词引导从句。 一、以that引导从句 当从句的意思已完整时,名词性从句用that引导,that在从句中不作任何句子成分,仅起连接作用。如: It is certain that he will do well in his new job. (主语从句) Do you know that he has been admitted to Beijing University? (宾语从句) My decision is that we are to start at 6 tomorrow morning. (表语从句)The news that our team had won the game excited everybody. (同位语从句) 当用that引导从句时,需注意以下情况: 1.在主语从句中,that一般不可省略,尤其是当主语从句位于句首时,它绝对不可省略。如: That our team had won the game was good news to us. 2.在宾语从句中,that可省略。但当句中有两个并列的宾语从句时,

引导第二个宾语从句的that不可省略。如: Everybody knows (that) the earth goes round the sun. Everyone knew what happened and that she was worried. 3.当句子是以it作形式宾语时,引导宾语从句的that不可省略。如:He has made it clear that he will not give in. 4.that一般不能引导介词的宾语从句,偶尔可在except, but, besides 和in(在于…;在…方面)的后面引导宾语从句,that不可省略。如:Your homework is quite good except that you have made two small mistakes. The reason lies in that she works harder than the others do. He differed from other people in that he always looked farther ahead in his work. 在其它介词后面需要用that引导宾语从句时,必须用it作形式宾语。如: You may depend on it that I shall always help you. 5.在表语从句和同位语从句中,that不可省略。如: My advice is that you must give up smoking right now. The fact that he is a thief shocked all of us. 二、以whether/if引导从句 引导名词性从句的whether/if意为“是否”。在使用时,要注意两者存在以下区别。 1.在主语从句中,whether既可引导位于句首的主语从句,也可引导

what与whatever引导的从句

what与whatever引导的从句 作者:佚名文章来源:本站原创点击数:777 更新时间:2014-6-28 what与whatever引导名词性从句的区别 what和whatever作为引导词来引导从句,它们之间到底有什么异同点?what只能引导名词性从句 ,如主语从句、宾语从句、表语从句和同位语从句,whatever既可以引导名词性从句,又可以引导让 步状语从句。 一、what引导名词性从句 what引导名词性从句时,可在主语从句、宾语从句、表语从句和同位语从句中充当成分,其意思 主要有以下两种:一是含有疑问含义,表示“什么……”;二是相当于“名词/代词+关系代词引导的 定语从句”结构,意为“……的事情/东西/样子/颜色”等。 下面我们看看what在句中的意思以及相应的句子转换。 1. I have tried my best to do what I can to help him. 为了帮助他,我已经尽我的最大努力去做我所能做的事情。 what引导宾语从句,在句中相当于the thing that。 2. Before a problem can be solved,it must be obvious what the problem is. 在解决问题前,我们必须要弄清楚问题是什么。 it 为形式主语,what引导主语从句,且在从句中作表语,what在句中意为“什么”,表示疑问 。 3. Do you have any idea what is actually going on in the classroom? 你知道教室里正在发生什么事情吗? what引导同位语从句,此处what也表示疑问,意为“什么”,且what在从句中作主语。 4. —Are you still thinking about yesterday’s game? —Oh,that’s ____. A. what makes me feel excited B. whatever I feel excited about C. how I feel about it D. when I feel excited

引导名词性从句的连接词

一、引导名词性从句的连接词 分类 引导名词性从句的连接词可分为三类: 连词(5个):that(无意义,不可省,不充当任何成分) 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(9个):what, whatever, who, whoever, whom, whomever, whose, which, whichever 连接副词(7个):when, where, how, why, whenever, wherever, however 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,只可用whether: 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" 5. 引导同位语从句 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 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。 Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。 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:

what引导名词性从句的五种用法

what引导名词性从句的五种用法(高考语法要点) 注意:请你在what引导的从句下面划线,并指出其充当的成分。 一、用法归纳 1. 表示“……的东西或事情”相当于the things that…:例如: They’ve done what they can to help her. 他们已经尽力帮助了她。 He saves what he earns. 他赚多少,积蓄多少。 What Mary is is the secretary. 玛丽的职务是秘书。 2. 表示“……的人或的样子”相当于the per son that…。如: He is no longer what he was. 他已经不是以前的那个样子。 He is what is generally called a traitor. 他就是人们通常所说的叛徒。 Who is it that has made Fred what he is now? 是谁把弗雷德培养成现在这个样子的? 3. 表示“……的数量或数目”相当于the amount/number that…。如:: Our income is now double what it was ten years ago. 我们现在的收入是10年前的两倍。 The number of the students in our school is ten times what it was before liberation. 现在我校学生的数量是解放前的10倍。 4. 表示“……的时间”相当于the time that…例如: After what seemed like hours he came out with a bitter smile.似乎过了几个小时他才苦笑着出来。 The young girl was too frightened to speak, standing there for what seemed like hours. 小女孩吓得不敢说话,在那儿站了几个小时。 5. 表示“……的地方”相当于the place that…。如: This is what they call Salt Lake City. 这就是他们称为盐湖城的地方。 In 1492, Columbus reached what is now called America. 1492年哥伦布到达了现在所称的美洲大陆。 What is now the North Sahara Desert was once a civilized world. 现在的撒哈拉沙漠的北部曾经是一个文明世界。 二、用法说明 (1) 这样用的what相当于“先行词+关系代词”,所以其前不能有先行词: 你喜欢什么就拿什么吧。 正:You can have what you like. / You can have everything (that) you like. 误:You can have everything what you like. (2) 有时what 可用作限定词,其后修饰一个名词: I gave him what books I had. 我把我所有的书都给他了。

名词性从句的概念以及四类引导词的用法

名词性从句的概念以及四类引导词的用法 一、名词性从句的概念 名词性从句,即指具有名词性质的从句,它包括主语从句、宾语从句、表语从句和同位语从句。名词性从句是英语学习中的一个语法重点,也是各类考试重点考查的内容之一。学习名词性从句主要应注意其引导词的用法与区别,从句的词序以及名词性从句与其他从句的区别等。从高考的考查的实际情况来看,名词性从句考得最多的是宾语从句,其次是主语从句,再次是表语从句,而同位语从句则很少考查。 二、名词性从句四类引导词的用法 1. 连接词that 只起连接作用,没有任何意思,也不充当句子成分,在宾语从句中可省略,但引导其他名词性从句时通常不省略。如: I hope (that) you enjoy your holiday. 希望你假期过得好。 That he likes you is very obvious. 很显然他喜欢你。 2. 连接词whether 也不充当句子成分,但有自己的意思,表示“是否”;引导宾语从句时,可换成if,但引导其他名词性从句时不能换成if。如: He asked whether [if] I would show him the way. 他问我是否可以给他带路。 Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句,不能用if 代替whether) 3. 连接代词who(m), whose, which, what 等,均有各自的意义,在从句中作主语、宾语、定语等。如: That’s why she w anted to leave. 这就是她想离开的原因。 When we arrive doesn't matter. 什么时候到没有关系。 Tell me which one you like best. 告诉我你最喜欢哪一个。 4. 连接副词when, where, why, how 等,也各自有自己的意义,在从句中作状语。如: The question is how we should carry out the plan. 问题是怎样执行这个计划。 When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。

引导主语从句连词有that,whether,who,what,whatever等定义: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 outing tomorrow remains unknown. (3)Who will be our monitor has't been decided yet. (4)Whom we must study for is a question of great importance. (5)What caused the accident remains unknown. (6)Whatever you did is right. (7)Whose watch was lost is unknown. (8)What we need is time.
