专题11名词性从句1.掌握连接代词和连接副词以及从属连词的用法2.掌握主语从句的考点3.掌握宾语从句的考点4.掌握表语从句的考点5.掌握同位语从句的考点1名词性从句的分类名词性从句，包括四种从句，即主语从句、宾语从句、表语从句、同位语从句。

因为主语、宾语、表语、同位语这四种成分均可以由名词构成，所以这四种从句在主句中都充当了名词的作用，故将这四种从句统称为名词性从句。

2名词性从句的连接词分类1.that（无含义，不充当成分）2.whether,if（有“是否”的含义，但不充当成分）3.连接代词：what,whatever,who,whoever,whom,whomever,whose,which,whichever.（在从句中做主语、宾语、表语和定语）连接副词：when,whenever,where,wherever,how,however,why（在从句中做状语）4.as if,as though,because（不充当成分，在名词性从句中只引导表语从句）一、主语从句1.主语从句在复合句中充当主语，大多数主语从句都可以用it作形式主语而把主语从句置于句尾。

2.that引导主语从句时可用it作形式主语，that不可省；what引导的主语从句表示＂……的东西＂时，一般不用it作形式主语；whatever，whoever，whichever一般也不用it作形式主语。

☞That she will succeed is certain.☞It is certain that she will succeed.注意：(1)在＂It is necessary/important/strange/natural...＋that从句＂结构中，从句谓语常用＂(should＋)动词原形＂形式。

3.主语从句的特殊用法（1）主语从句与定语从句的转换☞What is needed has been bought.☞All that is needed has been bought.所有需要的都被买了。

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，名词性从句分为主语从句、表语从句、宾语从句和同位从句。

（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.that引导主语从句时，不能省略。

e.g. That he suddenly fell ill last week made us surprised.3.用it作形式主语，主语从句放在句末。

It+系动词+形容词+that从句. necessary,right,likely,wrong,important,certain,clear...It+系动词+名词+that从句. a pity, a shame, a fact,no wonder...It+be +动词ed+that从句. said,told,reported,suggested,considered....It+特殊动词+that从句. seem,turn out,appear,matter...e.g. It doesn’t matter so much whether you will come or not.4.whether引导的主语从句可放句首，而if引导的主语从句不能放句首，只能放句末。

Whether the worked can be completed on time is doubtful.It is doubtful whether/if the work can be completed.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。

e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.3.一般不用if引导表语从句，用whether.The question is whether we can reduce the cost of the product.4.其他连接词：as if ,as though,because,as,like.It sounds as if/though he has been really ill.5. 主语为reason：表语从句中的连接词要用that，不用why.The reason why he was unhappy is that he has lost his keys.6.表语从句中的虚拟语气.（四）宾语从句1、宾语从句在复合句中作宾语。

语法复习之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：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）。

（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.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.（三）表语从句1、表语从句在复合句中作表语，位于系动词之后。

e.g. The question was who could go there.2、引导表语从句的连接词that有时可省去。

e.g. My idea is (that) we can get more comrades to help in the work.（四）宾语从句1、宾语从句在复合句中作宾语。

各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。

上述这四种从句均被称为名词性从句。

所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。

另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。

下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。

例如：That he will come to the discussion is certain.他来参加讨论是确定的。

That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。

When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。

主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。

例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。

高中英语语法之名词性从句在句子中起名词作用的句子叫名词性从句(Noun Clauses）。

名词性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，名词性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, whichever,whomever连接副词：when, where, how, why,how many,how much,how often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"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。
