高考英语名词性从句知识点一、that从句1、主语从句that从句作主语时，常用it作形式主语，常见的句型有：It+be+形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc. ) + that 从句It+be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc. ) + that 从句It+be+过去分词(said, reported, thought, expected, decided, announced, arranged,etc. ) + that 从句that可以省略，但that从句位于句首时，that不能省略。

2、宾语从句(1)常见的可以接that从句作宾语的动词有see, say, know, imagine, discover, believe, tell, show, think, consider, be sure, be afraid 等。

在可以接复合宾语的动词之后,如think, make, consider等，可以用it作形式宾语。

(2)That从句一般不能充当介词宾语，偶尔可作except, in的宾语。

3、表语从句(that不可省略)4、同位语从句连词that引导同位语从句时，应在某些抽象名词之后,如：fact, hope, desire, thought, suggestion, idea, news, problem, possibility 等，对前面的名词起补充说明的作用，that 在从句中不担当任何成分，不能省略。

二、whether/if 从句1＞在表语从句和同位语从句中，只能用whether不能用if；当主语从句放于句首时，只能用whether不用if；当it作形式主语，主语从句放在句末时用whether或if均可；discuss后引导宾语从句时，必须用whether。

高考英语语法复习名词性从句知识讲解一、与定语从句区别它们的性质不同，一个是名词，而另一个是形容词性。

名词性从句是独立的，而定语从句必须要依附先行词（相当于寄身虫）。

有时名词性从句可以转换成定语从句（必须加先行词）。

比如：What he said = The things that he said二、构成构成一个名词性从句就像是对一个陈述句进行特殊疑问句的提问，只不过不颠倒语序，如：He said something.What he said （名词性从句）What did he say? (特殊疑问句)三、分类（一）根据从句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四种。

（二）根据引导名词性从句的连接词可分为三类：1.连接词： that, whether, if （不充当从句的任何成分）2.连接代词：who, what, which, whose, whoever, whichever, whomever, whatever3.连接副词：where, when, why, how (how much, how long…), wherever, whenever, however1.主语从句【例句】1.That prices will go up is certain.= It is certain that prices will go up.2.How you travel means the difference between success and failure.3.Whether we go by train or by boat makes no difference.4.Who will write the poem has not been decided yet.5.What surprised us is that he lost in the game.6.What he left us was a large sum of money.7.When he will be back depends on the weather.8.Where we live doesn’t matter.9.How the pyramids were built was still a mystery.10.Watever he did is right.11.Whoever comes will be welcome.12.Whichever you want is yours.【注意点】That引导的主语从句中，that不能省略。

高中英语语法专攻-《名词性从句》【考点1-引导词】【考点2-主语从句】①定义：主语从句是指在复合句中充当主语的句子，它是名词的拓展，属于主语的第三个表达层次。

所以，主语从句和名词一样通常是出现在谓语动词的前面。

②主语从句的引导词：从属连词：that、whether、if（不可位于句首）连接代词：what, whatever/who, whoever/whom, whomever/whose,whosever/which,whichever连接副词：when, whenever/where,wherever/how, however/whythat引导主语从句（that无含义，在句中不作成分，不可省略）That youth is wholly experimental is known to us all。

众所周知，青春就是探索的岁月。

That she finished reading an English novel surprised us all.她读完了一部全英文小说让我们惊讶That you will win the medal seems unlikely.你赢得奖牌似乎是不可能的。

That he is still alive is a wonder.他还活着，真是奇迹。

That we shall be late is certain.我们要晚了，这是确定无疑的。

That she is still alive is a consolation.她还活着是使人感到宽慰的。

Whether引导主语从句（whether有含义“是否”，在句中不作成分，不可省）Whether she will come to the party makes no difference.她来不来参加聚会都没有关系。

It makes no difference whether/if she will come to the party.W hether he is coming or not doesn’t matter too much.他来或不来都不怎么重要It doesn’t matter too much whether he is coming or not.Who,whom, what, which,whose（连接代词）引导主语从句（连接代词有含义，在句中起名词性作用，担当一定成分）Who will be the leader of the team has not been decided yet.谁会成为这个队的领头人还没定下来。
