高二英语语法 名词性从句
高二英语语法名师讲解：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，名词性从句可分为主语从句、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w hether 和if(是否)，as if(好像)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。
高二第四堂课资料名词性从句
名词性从句在复合句中具有名词的性质的作主语、表语、同位语、宾语的从句叫名词性从句。
由一个含疑问意义的连词引起时，必须将该连词放在名词性从句的开头，且该从句语序不能倒装。
名词性从句要采用陈述句语序。
引导名词性从句的关联词引导名词性从句的关联词大致相同，它们分别是：连词：that, whether, if；关系代词：who, what, which , whom, whose, whatever, whoever, whomever, whichever；关系副词：when, where, how, why, however, whenever, wherever。
引导从句时一般不用逗号和主句分开。

That you don’t like him is none of my business.Whether she will come or not is still a question.2、it作形式主语引导主语从句。
如果主语从句太长，为避免句子结构头重脚轻，我们可用it作形式主语，而把主语从句放在主句谓语部分之后。
That引导的主语从句可用it代替，that 不可省略。
用作it作形式主语的结构：①It is/was +形容词+that 从句It was clear that…②It is/was +名词+that 从句It is a pity that…③It +不及物动词+that 从句I t seems that…④It is/was +过去分词+that 从句It’s said that…⑤其他It doesn’t matter that2、由连接代词引导的主语从句。
（1）连接代词who, what, which, whom, whose, whatever, whoever, whomever, whichever等，引导主语从句时，它们分别在从句中担任主语、宾语或定语，不能省略。

2.注意点
1).引导词that无实际意义,但不能省略. 2).只能用whether,而不能用if 引导. .注意:在表语从句中,当reason做主语时, 引导词只能 用that,不能用because,如:他迟到的原因是因为他没有 赶上早班车。 The reason why he was late was that he didn’t catch the early bus. 4. because It/ This/That is because… 那是因为…… He was late. That was because he was ill.
动词宾语、介词宾语、形容词宾语
注意1. 【有些动词不能直接跟 从句】
dislike, love, depend on,
help, take, like, hate, see to(负责,注意,照 料), appreciate+ it +从句….
Never take __B______for granted that I will help you. Better depend on yourself. A. that B. it C. which D. his
2).连接词that在从句中无实际意义,但不能省略. 例: 误: He will not come is true.
正: (That he will not come) is true.
3).whether可以引导主语从句,但if不能. 【it-主语从句】 有时为避免句子头重脚轻，常用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。主句的谓 语动词一般用单数形式。常用句型如下：
1.他是怎么成功的仍然是个谜。 How was he successful is still a puzzle. ( F ) How he was successful is still a puzzle. ( T )
