名词性从句引导词的判断选择思路分析
名词性从句引导词的选择思路分析
一、名词性从句的一般做题步骤：1.根据句意，分析句子结构，判断名词性从句的类别；2.根据句意，分析从句部分是否缺成分，（如果从句部分不缺成分，从that/if/whether中选择；如果从句缺少主语，宾语，个别缺表语，从连接代词what/whatever/who/whoever/which等中选择；如果从句缺少状语，从连接副词how/when/where/why等中选择。）3.分析选项中各引导词的区别。
二、名词性从句中的疑难、易混点：
1.whoever与who: 两者都可以做主语，宾语，但who是疑问代词，在从句中仍有疑问含义，翻译成“谁”，所引导的从句表示一件事；而whoever 无疑问含义，翻译成“…的人”，相当于“anyone who..”，所引导的从句表示“…的人”。类似地，what有疑问含义，“什么”；whatever无疑问含义，“无论什么”。
2.whatever 与no matter what：区别在于引导的从句有差别：whatever主要用来引导名词性从句（也可以引导让步状语从句）；而后者只可以引导让步状语从句（一般用逗号与主句隔开），不能用在名词性从句中。所以一定要分析从句类型。所有的疑问词+ever与no matter + 疑问词的区别同上。
3.which与what:主要区别在含义上，which“哪一个”，句中一般有供选择的范围；what“什么”，“…的”，一般无选择范围。eg, there are so many books here, so I don’t know which I should choose.
4.what与that区别：在所有名词性从句中，that不做成分，只起引导作用；而what在名词性从句中，起引导词作用，还有做主语，或者宾语等成分。在定语从句中，that可做主语，宾语；what不能用在定语从句中。

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.
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。

如何选择定语从句的引导词? *限制性定语从句 限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有 who,whom,whose,which,that等。who,whom,whose用于指人，whose有时也可指物，相当于of which；which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中 担任主语、宾语、定语等。 *非限制性定语从句 非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。不可用that引导非限制性 定语从句。关系词不可省略。 一、定语从句的引导词有关系代词who， whom，whose，which，that， as；关系副词when， where，why。定语从句中引导词的选用主要看先行词在定语从句中作什么成分或者是定语从句中缺什么成分。 1．定语从句中缺主语，修饰人时用who ／that，修饰物时用which ／that引导。如： Is this the factory which ／that makes TV sets？ The man who ／that visited our school is from Australia．
2．从句中缺宾语，修饰人时用 who ／whom ／that或省略引导词；修饰物时用which ／that或省略引导词。如： Gone are the days which ／that we spent together in the village． He is the man who ／whom ／that I think to be worthy of our praise． 3．从句中缺时间状语，用when或介词＋which引导。如： The day finally came when ／on which I was given a job． We'll put off the outing until next week，when we won't be so busy． 4．从句中缺地点状语，用where或介词＋which引导。如： Please put the letter on the desk where ／on which he can easily find it．5．从句中缺原因状语或先行词是 reason时，引导词用why ／for which ／that。如： This is the reason why ／for which ／ that he didn't come to the meeting．6．从句中缺定语，人和物都用 whose引导。如： A child whose parents are dead is called an orphan． Please pass me the dictionary whose cover is black． 7．当先行词是way时，其定语从句的引导词用in which ／that。如：
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
特殊疑问词引导的宾语从句
特殊疑问词引导的宾语从句 一、由连接代词who, whom, whose, what, which和连接副词when, where, why, how引导的宾语从句。这些连接代词和连接副词在宾语从句中充当某个成分。例如：Do you know who (whom) they are waiting for? 你知道他们在等谁吗？ I can't imagine why he did that thing．我不能想像他为什么做了那件事。 注意： （1）由于宾语从句要求陈述句语序，故而在从句中它变成了陈述语序。请看下列两组句子： How much does this coat cost? ——I want to know how much this coat costs． Where did you go yesterday? ——Please tell me where you went yesterday． （2）当疑问代词what，who在特殊疑问句中做主语时，该特殊疑问句本身就是陈述句语序，所以当该句用来做宾语时，语序不需要调整。 例如：What's wrong with you? 怎么了? ——He asked the girl what was wrong with her．What's the matter? 怎么了? —— He asked the girl what was the matter． What has happened to him? ——We want to know what has happened to him． 小试牛刀：1. I said to her. Where did you go during the holiday? 2.Mr.Ding asked . What did you do during the holiday? 二、语从句的时态 1．若主句为一般现在时或一般将来时，则从句的时态不限可视句子意义使用所需要的任何时态。 例如：Don't you think Jim is speaking too quick.难道你不认为吉姆讲的太快了吗？ He says he will come back.他说他会回来。 2．若主句是祈使句，从句谓语动词也可用所需要的任何时态。 例如：Show me which picture is yours.让我看看哪张照片是你的。 Please tell us where we will go.请告诉我要去哪里。 3．若主句是一般过去时，从句必须用过去时态的某一种。 例如：I knew she had swept the floor already.我知道她已经扫过地了。 He asked if I was doing my homework this time yesterday.他问我昨天这个时候是否在做作业。 4．若从句叙述的是客观真理、自然现象或永恒不变的规律时，则不受主句时态的限制，仍用一般现在时。 例如：Our teacher told us light travels much faster than sound.老师告诉我们光传播的速度比声音快得多。 They knew the sun is much bigger than the earth then.他们那时就知道太阳比地球大得多， He said that one and one makes two.他说一加一等于二。 小试牛刀： 1、The radio says it __________ cloudy tomorrow. (be) 2、The headmaster hopes everything __________well. (go) 3、I hear they __________ it already. (return) 4、He said that they __________ members of the Party since 1948. (be) 5、Our teacher told us in class the sun __________ in the east. (rise) 三、特殊的宾语从句———间接引语 当直接引语是特殊疑问句，改为间接引语时，用原句中的疑问词做连接词，疑问语序改为陈述语序。 例如：“What do you want?” he asked me. →He asked me what I wanted. He asked her,“Where are you going?” →He asked her where she was going. 小试牛刀： 1、She said to Tom,“How are you feeling now?”→. 2、The scientist asked me,”what are you doing?”→. 3、She asked,”How many boys are there in your class?”→ .
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：
