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。

宾语从句通常以that引导,也可以用whether或if 引导。
需要注意的是,当主句的动词是说、tell、ask、think、believe、know等表示说话、思考、感觉的动词时,常用连词that引导宾语从句,但如果宾语从句的主语与主句的主语相同,可以省略连词that。
例如:- I know that he is a good student.- She asked me if/whether I had finished my homework.- He told her (that) he loved her.3.表语从句表语从句在句中充当表语的作用。
表语从句通常以that引导,也可以用whether或if 引导。

高考英语名词性从句知识点一、that 从句1、主语从句(1)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(2)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。
名词性从句名词性从句指在复合句中起名词作用的从句,它在句子中可作主语、宾语、表语或同位语。
名词性从句既是中学英语教学的重点,也是高考考查的热点。
一、名词性从句的分类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。
其连接词有that, if, whether;连接代词who, what, which;连接副词when,where, how, why等。
考查热点一:对主语从句的考查主语从句在复合句中充当主语,它可以放在主句谓语动词之前。
但为了保持句子平衡,多数情况下可用it 作形式主语,而把主语从句置于句尾。
考查热点二:对宾语从句的考查宾语从句在句子中作及物动词或介词的宾语。
如果主句的谓语动词是及物动make, find, see, think等,则把宾语从句置于宾语补足语之后,用 it 作形式宾语。
另外,某些作表语的形容词,如 sure, happy, glad, certain等之后也可以带宾语从句。
考查热点三:对表语从句的考查表语从句在句子中作表语,位于主句中的系动词之后。
一、什么是表语( predicative)在形式上,位于系动词后的就是表语。
从含义上讲,表语是回答主语“是什么”或“怎么样”的语法成分。
即是指“是”字句“是”字后面的成分。
表语就是起表述作用的句子成分。
它修饰的是主语。
表语是用来说明主语的身份、性质、品性、特征和状态的。
表语须和连系动词一起构成句子的复合谓语。
表语常由名词、形容词、副词、介词短语、不定式、动词的-ing、动词的-ed、从句来充当,它常位于连系动词( be, become,appear, seem等)之后。
Albert Einstein was a famous professor of physics.二、不定式、动名词与分词作表语的区别不定式和动名词作表语相当于一个名词作表语,含义是回答主语“是什么”;分词作表语相当于形容词作表语,含义是回答主语“怎么样”。
