名词性从句中的引导词

名词性从句中的引导词—that、if与whether

一、that引导的名词性从句

that引导名词性从句时，可引导主语从句、表语从句、宾语从句和同位语从句，that 在从句中既不充当任何成分，也无实际意义，仅起着连接句子的作用。例如：

1) That a new teacher will take charge of our class is true. (that引导主语从句)

2) Can you believe (that) in such a rich country there should be so many poor people?

( that引导宾语从句，that可省略)

3) We heard the news that our team had won. (that引导同位语从句)

4) Another problem is that good soil is gradually lost. (that引导表语从句)

注意：that在以下情况下不能省略

①that引导的宾语从句作介词宾语时，that不可省略。例如：I know nothing about him except that he is from the south.

②that引导的从句位于句首时，that不可省略。例如：That he finished writing the composition in such a short time surprised us all.

③及物动词后由that引导的两个或两个以上的并列宾语从句中，只有第一个that可省略。例如：Mother said (that）you needn’t worry and that she would help you.

④主句谓语动词与that从句之间有插入语时，that不可省略。例如：Mother judged that, because Jim was still a child, he didn’t understand her words.

二、if和whether引导的名词性从句

if和whether引导的宾语从句表示“是否”之意时，可以互换。例如：I wonder whether/if daughters are valued as much as sons in the countryside.

但在以下几种情况下，只能用whether(不用if)引导名词性从句：

1) 在句首引导主语从句时，或引导表语从句、同位语从句时，只能用whether。例如：①Whether she will go abroad or not is unknown. (whether引导主语从句)

②The question is whether we can collect enough money for the project. (whether引导表语从句)

③I have no idea whether Liu Xiang will win the championship in the 2008 Olympic Games. ( whether引导同位语从句)

2) 引导介词宾语从句时只能用whether。例如：

It all depends on whether he is coming back on time or not. ( whether引导的从句作介词on的宾语)

3) 与or not连用或后接动词不定式时，只能用whether。例如：

①I wonder whether you will help me or not. (whether与or not连用)

②Can you tell me whether to go or stay? (whether后接动词不定式)

三大类从句的引导词

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. （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 made a 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 vacation. （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 to Taiwan)

限制性定语从句与非限制性定语从句

限制性定语从句与非限制性定语从句 2．关系代词which与as引导非限制性定语从句的区别。 （1）which与as都可以引导非限制性定语从句，which引导定语从句要置于先行词后面，而as引导的定语从句位置相对灵活，可放在句首，也可以放在句后 eg.正像他所意识到的那样，我对他非常有用 As he realized, I was very useful to him. 空气，众所周知，是一种气体 Air, as we know, is a gas. 他是个外国人，正像我从他口音判断的那样。 He was a foreigner, as I know form his accent. 他又来晚了，这一点使老板很生气 He came late again, which made his boss angry. (2)当定语从句位于主句后面，纯粹表示主句所述的内容，往往用which；当定语从句中有“如同……那样”的含义时，用as比用which更常见。 Eg.妈妈老把我当成小孩对待，让我无法忍受 Mummy always treats me just like a baby, which I can’t bear. 事与愿违，这是常有的事 Things will turn out contrary to on e’s wishes, as is often the case. (3)“介词+关系代词”结构的定语从句，必须用which,不能用as. Eg.我们周围有很多氧气，没有他们我们无法生存 There is a great deal of oxygen around us, without which we could not live. 3．引导限制性定语从句时which与as的区别 定语从句前面有such, as, the same 时，引导定语从句的关系代词用as,不用which. Eg 所需要的字典有许多都有了

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.

(完整word版)时间状语从句地引导词

时间状语从句的引导词 when, before, after, as, while, till/until, since，whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析： (1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用短暂性动词又可用延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句： I’ll call you when I get there. 我一到那里就给你打电话。 When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。

When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be 可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如： When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。 When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如 Study while you study; play while you play.

as引导定语从句的用法

as引导定语从句的用法 as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which 引导的非限制性定语从句只能放在主句之后。另外，as有“正如……，正像……”的意思 (1) As is known to all, China is a developing country. (2) He is from the south, as we can see from his accent. (3) John, as you know, is a famous writer. (4) He has been to Paris more than several times, which I don’t believe. ================================ As 的用法例 1. the same…as；such…as 中的as 是一种固定结构, 和……一样……。 I have got into the same trouble as he (has). 例2. as可引导非限制性从句，常带有'正如'。 As we know, smoking is harmful to one's health. As is known, smoking is harmful to one's health. As是关系代词。例1中的as作know的宾语； 例2中，它充当从句的主语，谓语动词know要用被动式。 一、“as / which”特殊定语从句的先行成分 1. 形容词或形容词短语作先行成分, 具有形容词意义的介词短语也可以充当先行成分，如： My grandmother’s house was a lways of great importance to me, as my own is. 在一定的语言环境里，有些名词可以具有形容词的性质。这些名词主要是那些表示人的身份、职业、状态的名词。值得一提的是，在这些具有形容词性质的名词之后，引导定语从句的关系代词不能用who / whom. 2. 动词短语先行成分。 这种动词短语既可是限定形式也可是非限定形式。如果是动态动词短语，它们在从句中就一般有限定或非限定形式的替代动词do和as / which一起代替。do可以出现，也可以不出现，但不能用其它动词代替。 3. 句子作先行成分。 这句子可以是整个主句也可以只是主句中的一个从句。有时是连续几个句子，有时甚至可以是一个完整的故事。 二、“as/which”特殊定语从句在句中的位置 由于先行成分的构成成分不同，“as/which”特殊定语从句在句中的位置有以下几种情况：1. 形容词做先行成分时：形容词或形容词短语（含具有形容词性质的名词）作先行成分，“as / which”特殊定语从句置于先行成分之后。 2. 动词短语作先行成分时：动词短语作先行成分时，“as / which”特殊定语从句置于先行成分之后。但是，当从句中含有表示主观意志的插入成分时，“as”特殊定语从句可以移至句子之首。 3. 句子作先行成分时：“as”特殊定语从句的位置较灵活，可以置于先行成分之前、之中或之后。但如果先行成分是直接引语，“as”特殊定语从句多在先行成分之前。如果先行成分是否定句，“as”特殊定语从句与否定词的相对位置不同可以使它产生不同的意义。由于“as”特殊定语从句具有这一特点，所以有时它的位置不能随便移动。在非正式的文体里，“which”特殊定语从句可以出现在先行成分之中。

where引导定语从句的用法

Where引导定语从句,先行词不一定都表 示地点 1、We will discuss a number of cases __ beginners of English fail to use the language preperly、A、which B、as C、why D、where 2、He was driving so fast as to get himself into a dangerous situation ___he is likely to lose the control over his car、 A、which B、as C、why D、where 两道题都选where ,但就是case, situation都不就是地点,如何理解？ 在“先行词不就是表示地点的名词”的前提下,如何判断就是否使用关系副词where来引导定语从句的问题就是一个高频考点。就就是说,关系副词where 所指代的先行词不只就是表示地点的名词。

用Where引导定语从句,先行词不一定都表示地点按照通常的理解,当where 引导定语从句时,它的先行词就就是表示地点的名词,但事实并不就是我们想象的那么简单。很多情况下,where所指代的先行词并不表示地点。请瞧以下几个例句: Other research, where siblings have been asked to say who their mother and father favor, suggests that mothers do tend to show a preference for their first-born son, but fathers often show great affection for their youngest daughters、 1、Remember that the best relationship is one where your love for each other is greater than your need for each other、请记住,最深的感情关系表现为彼此间的爱超过彼此间的需要。

(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

which引导的定语从句的用法

which引导的定语从句的用法 WHICH可以引导定语从句，修饰表示事物的先行词，在定语从句中充当主语、宾语或者表语。例如：HEWASREADINGABOOK， WHICHWASABOUTWAR.他正在读一本关于战争的书。（关系代词WHICH在修饰BOOK的定语从句中充当主语。） HEWASREADINGABOOK，WHICHHEHADBOUGHTFROMLONDON.他正在读一本书，这本书是从伦敦买回来的。（关系代词WHICH在修饰BOOK的定语从句中充当宾语。） WHICH引导非限定性定语从句时有一个特殊用法，即它所引导的非限定性定语从句修饰主句中更多的部分甚至整个主句（这时被定语从句所修饰的“先行词”要作广义理解），WHICH仍在定语从句中作主语、宾语或表语。例如：HESETFREETHEBIRDSHAPPILY， WHICHWASACELEBRATIONFORHISSUCCESS.他开心地把鸟放了，这是对他成功的一种庆祝。 把非限定性定语从句“WHICHWASACELEBRATIONFORHISSUCCESS”的先行词视为主句中的“THEBIRDS”显然不符合整句的语境，被 “WHICHWASACELEBRATIONFORHISSUCCESS”所修饰的是整个主句，WHICH所引导的这类特殊的非限定性定语从句对主句所叙述的情况进行某种意义的补充说明，WHICH常可译为“这一点，这件事”。 ［考题1］ YOUCANFINDWHATEVERYOUNEEDATTHESHOPPINGCENTRE， ____ISALWAYSBUSYATTHEWEEKEND.（2006上海春） A.THAT B.WHERE C.WHAT D.WHICH ［答案］D

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：
