名词性从句用法详解
名词性从句用法详解 一、概说 名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。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。 二、名词性从句的一般引导词 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 wanted 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。 三、名词性从句的重要引导词 1. what 用于引导名词性从句是一个十分重要的引导词，它可引导主语从句、宾语从句和表语从句，但不用于引导同位语从句。它引导的名词性从句有两个意思是：一是表示“什么”，带有疑问意味；二是表示“…所…的”，相当于一个先行词后接一个关系代词。如： I don’t know what you want. 我不知道你想要什么。 I don’t know what you want is this. 我不知道你所想要的是这个。 2. what 引导名词性从句时可用作限定词，其后修饰名词。如： 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。 注：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，并且后接不可数 名词时，有时可有little修饰，两者的区别是：what+不可数名词=所有的都，what little+不可数名词=虽少但全部。如：

A. which B. that C. what D. where 【答案】 C 【解析】【分析】考查主语从句。What引导主语从句______ I call my “home”且 What在从句中充当call的宾语。故选C。 4．________ we may find interesting is that it usually takes more to be polite. A.

It doesn’t matter whether they will come or not. It occurred to him that he failed in the examination. What he wants to tell us is not clear. Who will win the match is still unknown. Whichever book you like would be bought for you as a present. Whatever I do is for the good of you. Whoever leaves the room last ought to turn off the lights.

Whether he can finish his task on time is of great importance. 他是否能按时完成任务非常重要。 Whether you can succeed or not depends on how hard you work at it. 你能否成功取决于你努力的程度。 2.连接代词：在从句中起名词或代词的作用，常作从句的主语、宾语、表语或定语，有具 体意义且不能省略。常见的连接代词有who, whom, whose, what, which, whoever, whomever, whatever, whichever。 What we should do with the problem is undecided. 我们如何处理这个问题还未作出决定。（what引导主语从句，不表疑问意义） Whom the letter was from is still unknown.
名词性从句总结
划从句的方法的方法：通常从引导词（即空）开始划到往后出现的第二个谓语动词之前 删除法（成分残缺的是名词性从句，不残缺的是的定语从句，状语从句，同位语从句） 引导名词性从句的连接词可分为三类： 连词（5个）： that （本身无意义。引导单一的宾语从句时that常可省略，但引导主语从句、表语从句、同位语从句时that通常不被省略） whether,if （均表示“是否”表明从句内容的不确定性） as if ,as though （[1] 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（10个）： what/ whatever, who/ whoever, whom/ whomever, whose/whosever, which/ whichever 连接副词（7个）： when/ whenever, where/ wherever, how/ however, why 1.whether引导主语从句(位于句首时) ，表语从句，同位语从句，不用if （.if只能引导两种名词性从句：宾语从句；不放于句首的主语从句。） 2. whether从句作介词宾语，不用if I’m thinking about whether I should quit my present job.我正在考虑是否辞去现在的工作。 3. if与whether都可以与or not连用，但后面紧跟着or not时只能用whether； 4.在动词不定式之前，只能用whether，不能用if。 I don’t know whether or not to tell her the news.我不知道要不要告诉她这个消息。 5.在容易引起混淆产生歧义的情况下，就不可用if，而须用whether。 6.位于discuss后引导宾语从句时whether They are discussing whether the meeting will be put off.他们正在讨论会议是否会被推迟。 通俗来讲，whether在大多数情况下都可以用,而if则不然,有wether和if时一般选wether 不会有错,但是如果所需的意思是"如果",自然只能选if了 考查名词性从句的语序问题 名词性从一般为陈述句语序（连接词+主语+谓语+其他成分） 但what's the matter、what's wrong 本身为陈述语气，则保持原有语序不变。
高中英语名词性从句 which的用法
一、在名词从句中连接词which 有两种词性, 常用来引导宾语从句： 1. [连接代词] 哪个 1）用作从句的主语，如： He wanted to know which was on the table. 他想知道哪一个在桌子上。 2) 用作从句的宾语，如： He asked me which I liked best. 他问我最喜欢哪一个。 2. [连接形容词]放在名词前作定语，表示“哪个XX，哪些XX”，如： Do you wnow Which country is the largest? 你知道哪国家一个最大? Could tell me which children made him still more angry. 能告诉我那些 孩子使他更加生气了。 二、which 除引导上述宾语从句外，还可以引导主语从句和表语从句。 1. 主语从句(常用形式主语it) It was clear which children made him still more angry. 显而易见那些孩子使他更加生气了。 It is known to us which he liked best. 众所周知他最喜欢哪一个。 2. 表语从句 That was which children made him still more angry. 那就是那些孩子使他更加生气了。 This is which he liked best. 这就是他最喜欢哪一个。 三、which 与what 的区别 用在名词从句中，which 意思是“哪一个/那一些”，what 意思是“所...的”，后者等于“先行词+关系代词”，如你的补充问题就需要选择what： It's quite different from what I read last month. = It's quite different from (the one that) I read last month. 这本书与我上周所读过的那一本区别很大。 1.that在所有名词性从句中无成分无意义。 2.which强调哪一个，有一个选择的范围。 从句中from后边缺宾语，所以要选择的是宾语从句的引导词，首先that引导宾语从句时，不做介词宾语（除了in,except,but) 其次read后边缺宾语，也就是从句中缺成分，参见上面第一条，所以排除that.B选项which指哪一个，这里
名词性从句总结以及注意点
名词性从句 第一节主语从句 引导主语从句的连接词有：that, whether, who, which, what, when, where, how, why等 That she was invited to the ball made her very happy. Whether he will come to the ball has nothing to do with me. Whoever wants to see the film may get a ticket free. Which team will win the match is still unknown. What interests you doesn’t interest him. Where they had stayed was still unknown. When they will have a meeting hasn’t been decided. 注意：1从句作主语谓语动词用第三人称单数形式。Who will go is not important. 2为了调节句子平衡，常用it作形式主语。It i s a pity that he didn’t come yesterday. It’s necessary that every League member (should) take the lead and work well. It’s suggested that a modern hotel (should) be put up at the foot of the hill. 3陈述句部分的主语是从句时，其反意疑问句部分的主语用it. How he became a scientist is known to us all, isn’t it? 第二节宾语从句 作动词、介词或形容词宾语的从句。以连词 that who whom whose what 等引导，在句子中充当宾语 I think (that) you will like the pictures. I feel it important that they finish their own task in time. They are worrying about whether they can get there in time. You can write about whatever topic you can think of. 一宾语从句三原则：语序；时态；引导词。1.语序：宾语从句用陈述句语序。 I wonder what he is writing to me about但是：what’s the matter/wrong (with)……语序不变.The owner came up to see what was the matter with me/what was wrong with me 2.时态：宾语从句谓语动词的时态与主句谓语动词的时态保持一致。 (1).如果主句的谓语动词是一般现在时或一般将来时，宾语从句用它本身的时态。I hear he will come back in an hour.(2).如果主句的谓语动词是一般过去时，宾语从句则用相应的过去时态。 She said that he had never been to the Great Wall.(3).如果宾语从句的内容是客观真理时，宾语从句仍然用一般现在时。The teacher told us that the earth goes around the sun. / light travels faster than sound.3.引导词：（1）由that引导（2）由if/whether引导（3）由特殊疑问词引导 二 it在宾语从句中的应用： 1. vt.+it+adj./n.+that-clause 或wh-clause。 She has made it clear that she will have nothing to do with him.

名词性从句知识点总结
名词性从句 名词性从句相当于名词，可分别作主句的主语、表语、宾语和同位语。因此，名词性从句厅分为主语从句、表语从句、宾语从句和同位从句。 （一）引导名词性从句的连接词 1、连接代词：who, whose, whom, what, which。有词义，在从句中担任成分，如主语、表语、宾语、或定语等。 2、连接副词：when, where, why, how。有词义，在从句中担任成分，作状语。 3、连接词：that, whether, if, as if。that 无词义，在从句中不担任成分，有时可省略；if (whether), as if虽有词义，但在从句中不担任成分。 注意： 1、连接代词与连接副词在句中不再是疑问句，因而从句中谓语不用疑问式。连接代词与连接副词在从句充当句子成分，连接词whether 和if（是否），as if（好象）在从句中不充当句子成分，只起连接作用。根据句义，如果连接代词与连接副词，whether、if 和as if都用不上时，才用that作连接词（that本身无任何含义）。 2、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. （二）主语从句 1、主语从句在复合句作主语。 e.g. Who will go is not important. 2、用it作形式主语，主语从句放在句末。 e.g. It doesn’t matter so much whether you will come or not. 主要句型有： （1）It+be+形容词+that从句。 It is probable that he told her everything. 很可能他把一切都告诉她了。 （2）It+be+名词词组(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that从句。It’s no surprise that our team should have won the game. 我们没赢这场比赛真意外。 （3）It+be+过去分词+that从句。 It is said that Mr. Green has arrived in Beijing. 据说格林先生已经到了北京。 （4）It+seem, happen等不及物动词及短语+that从句。 It seems that Alice is not coming to the party at all. Alice似乎不来参加晚会。 （5）It+doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。 It doesn’t matter whether she will come or not. 她是否来这无关紧要。 It makes no difference where we shall have the meeting. 我们在哪里开会毫无区别。 3、that引导主语从句时，不能省略。 e.g. That he suddenly fell ill last week made us surprised. 4、当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。 What we need is more time and money. What we need are many more books. 5、if不能用在主语从句中，而是用whether Whether he left (or not) is unknown 6、引导主语从句的关联词有三类： (1)从属连词that。
