考点2宾语从句1. 宾语从句的引导词引导词作用连接词that, whether, if 只起连接作用，不在从句中作成分连接代词what, who, whom,which, whichever,whatever, whoever在从句中作主语、宾语、表语或定语连接副词when, where,how, why在从句中作状语Our teachers always tell us to believe in what we do and who we are if we want to succeed.老师总是告诉我们，如果我们想要成功，要相信我们所做的事情和我们自己。

(2)一般情况下介词后只能用wh类连接词引导宾语从句。
介词后的宾语从句，连接词表示“是否”时，只能用whether，不能用if。
宾语一般放在及物动词或介词之后，但是，在下列情况下，须用it作形式宾语，而将真正的宾语(常为不定式或从句)后置。

3. 宾语从句的时态一般情况下，宾语从句须与主句的时态保持一致，即主句是一般现在时，从句可根据具体情况选用合适的时态；主句为过去的某种时态，从句须用相应的过去的某种时态。
当从句的内容为真理或客观事实时，须用一般现在时。
考点3表语从句1. 表语从句的引导词引导词作用连接词that, whether 只起连接作用，不在从句中作成分连接代词what, who, whom,which, whichever,whatever, whoever在从句中作主语、宾语、表语或定语连接副词when, where,how, why在从句中作状语The most important result for the user is that the product does what is intended.对用户来说，最重要的是产品达到了预期的效果。

同位语从句的引导词：that, whether, how, where, when, why等。
The fact that you are wrong can't be changed by you or me.你错了这个事实，是你我不能改变的。
that引导同位语从句和定语从句的区别：that引导定语从句时，that既起引导词的作用，又在从句中充当句子成分；如果在从句中作宾语，that还可以省略，所修饰的名词指物时可用which替换。
引导同位语从句时，that在从句中不充当任何句子成分，不能省略。
The news that they had won the game soon spread over the whole school.他们比赛获胜的消息很快传遍了学校。
(同位语从句)The news that you told me yesterday was really disappointing.你昨天告诉我的消息实在令人失望。
(定语从句)考点5名词性从句重点辨析that引导名词性从句时，在主从句中不充当任何句子成分，也没有任何含义；而what 引导名词性从句时，在主从句中都要充当一定的句子成分，what可以分解成定语从句中的“先行词＋关系代词”，即常说的“先行词＋that/which/who”。
It's a shame that he has made such a mistake.真遗憾，他犯了这样一个错误。
I will do what I can (do) to help him.我将尽我所能帮助他。
2. 同位语从句与定语从句的区别判断是定语从句还是同位语从句可以用“加词”的方法，即在名词和从句之间加入一个be动词，如果句子意思成立，则是同位语从句，否则，则是定语从句。
试比较：①The notice that the meeting had to be put off was true. (同位语从句)→The notice was that the meeting had to be put off.②The notice that he read just now was true. (定语从句)3. whether与if引导的名词性从句(1)whether引导的主语从句既可放在句首也可放在句末，但if引导的主语从句只能放在句末，且前面需用it作形式主语。
Whether it is true remains a question.这是否是真的依然是个问题。
It is unknown if he will attend the meeting.他是否会来参加会议还不清楚。
(2)whether与if引导宾语从句时，大多数情况下可以互换，后面直接跟or not时用whether，用于介词后引导宾语从句时也用whether。
We don't know whether or not she was ready.我们不知道她是否准备好了。
I'm interested in whether you've finished the work.我对你是否完成了这项工作感兴趣。
(3)whether可引导表语从句和同位语从句，而if不可以引导这两种从句。
The question is whether it is worth doing.问题是它是否值得去做。
The question whether the work was worth doing has not been decided.这项工作是否值得去做的问题还没有确定。
2023届高考英语语法名词性从句精讲之四大从句用法大全讲义
2023年高中英语语法名词性从句精讲之：四大从句用法大全主语从句主语从句的概念：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。
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。
主语从句用法：1、主语从句的引导词：主语从句通常由连词that和whether、连接代词或连接副词以及关系代词型what引导：如：That he is still alive is a wonder. 他还活着，真是奇迹。
When we arrive doesn't matter. 什么时候到没有关系。
What we need is money. 我们需要的是钱。
What I want to know is this. 我想知道的就是这一点。
Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
2、主语从句与形式主语it：有时为了考虑句子平衡，通常在主语从句处使用形式主语it，而将真正的主语从句移至句末。
这分三种情况：(1)对于以连词that引导的主语从句，通常用形式主语代主语从句：如：It's a pity that he didn't come. 很遗憾他没来。
(2)对于以连接代词(副词)引导的主语从句，可以使用形式主语代主语从句，也可直接在句首使用主语从句：如：Whether they would support us was a problem. 他们是否会支持我们还是一个问题。
It was a problem whether they would support us. 他们是否会支持我们还是一个问题。
(3)对关系代词型what引导的主语从句，通常不用形式主语，总是主语从句放在句首：如：What we need is money. 我们需要的是钱。
高考英语一轮复习 语法精讲精练 名词性从句用法
名词性从句用法讲解与专项练习题名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
高考常从连接词的选择、语序、语气、时态等方面来考查。
名词性从句中的连接词有连词that / whether / as if，连接代词what / who/ which /whose / whatever / whoever / whomever / whichever，连接副词where /when /why / how / wherever / whenever。
第1讲引导名词性从句的连接词考点1. 引导名词性从句的连接词有哪些有学生认为，引导同位语从句只能用that, 这句话对吗？先看下面几个句子。
①I have no question that he will come.②I have a question whether he will come③I have a question when he will come.我们可以看出：上面三个句子中question后面都是同位语从句，都是说明question的内容的。
在句①中，同位语从句的原句是陈述句，由that引导；在句②中，原句是一般疑问句，由whether引导；在句③中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。
其实，所有名词性从句的连接词都有上面的三种情况。
宾语从句：I don’t know that he will come.I don’t know whether/if he will come.I don’t know when he will come.表语从句：What I don’t know is that he will come.What I don’t know is whether he will come.What I don’t know is when he will come.主语从句That he will come is obvious.Whether he will come isn’t known yet.When he will come isn’t known yet.1.【2010浙江】It is uncertain ______ sideeffect the medicine will bring about,although about two thousand patients havetaken it.A. thatB. whatC. howD. whether2.【2012全国新课标】It is by no means clear______ the president can do to end the strike.A. howB. whichC. thatD. what3.【2012山东】It doesn’t matter ______ you payby cash or credit card in this store.
