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。

名词性从句是一种具有名词功能的非独立分句。

具体用法见下表：主语从句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。

(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。

)►It makes no difference where we shall have the meeting.我们在哪开会无所谓。

【注意】(1)常见的it替代that引导的主语从句的句式主要有以下几种：①It＋系动词＋形容词(necessary/right/likely/important/certain...)＋that从句②It＋be＋名词(短语)(a pity/a shame/good news/a fact/an honour...)＋that从句③It＋be＋过去分词(said/told/heard/reported/decided/suggested...)＋that从句④It＋特殊动词(seem/appear/happen/matter)＋that从句(2)在“It is necessary/important/natural...＋that从句”的结构中，从句谓语常用“(should ＋)动词原形”。

宾语从句1．动词find, feel, think, consider, make, believe等后有that引导的宾语从句作宾语补足语时，则常用it作形式宾语而将that宾语从句后置。

►I think it necessary that we take plenty of boiled water every day.我认为每天摄入足量的白开水很有必要。

2．有些动词(短语)不能直接跟宾语从句，需要借助形式宾语it。

常见的有hate, enjoy, like, dislike, love, appreciate, see to等。

名词性从句李仕才考点一名词性从句(宾语从句，表语从句)1．宾语从句宾语从句就是在复合句中作宾语的名词性从句，通常放在主句谓语动词(及物动词)、介词或形容词之后。

(1)作动词的宾语①由that引导的宾语从句(that通常可以省略)Do you know(that) he has joined the army?你知道他参军了吗？②由what，whether(if)引导的宾语从句She did not know what had happened.她不知道发生了什么事。

注意：if引导的从句不能作介词的宾语。

③动词＋间接宾语＋宾语从句She told me that she would accept my invitation.她告诉我她会接受我的邀请的。

(2)作介词的宾语It depends on whether you can do the work well.这取决于你是否能把工作干好。

(3)作形容词的宾语I'm sure that he will pass the exam.我确信他会通过考试。

注意：①that引导的从句常跟在下列形容词后作宾语：anxious，aware，certain，confident，convinced，determined，glad，proud，surprised，worried，sorry，thankful，ashamed, disappointed，annoyed，pleased，satisfied，content等。

②it不仅可以作形式主语，还可以作形式宾语，而真正的宾语that从句则放在句尾，特别是在带复合宾语的句子中。

We consider it necessary that he should improve his pronunciation.他应当改进他的发音，我们认为这是有必要的。

(4)否定的转移若主句谓语动词为think，consider，suppose，believe，expect，fancy，guess，imagine等，其后的宾语从句若含有否定意义，一般要把否定词转移到主句谓语上，从句谓语用肯定形式。

高中英语名词性从句详细讲解与练习在句子中起名词作用的从句叫名词性从句。

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，因此根据它在句中不同的语法功能，名词性从句又可分为主语从句、宾语从句、表语从句、同位语从句。

引导名词性从句的词叫做连接词，包括：1.连词（在名词性从句中只起连接作用，不作成分）2.连接代词（在名词性从句中作主语、宾语或表语）3.连接副词（在名词性从句中作状语）所有的名词性从句的语序都是陈述语序。

I主语从句：是在主句中作主语的从句。

它由连接词引导，通常位于谓语动词之前。

连接词：1.连词：在从句中不充当任何成分，常见的引导主语从句的连词有that, whether oThat he got the first prize excited him much.他获得一等奖一事使他非常兴奋。

It is doubtful whether we can get there on time.我们能否按时到达那儿还不确定。

D that引导的主语从句:在从句中不作任何成分，也没有实际意义。

一般情况下that不可省略。

That light travels in straight lines is known to all.众所周知，光沿直线传播。

That you don't like him is none of my business.你不喜欢他不关我的事。
