高中英语名词性从句专项练习引导名词性从句的连接词可分为三类：连接词：that, whether, if （不充当从句的任何成分）连接代词：what, whatever, who, whoever, whom, whose, which.连接副词：when, where, how, why主语从句有时为避免句子头重脚轻，常用形式主语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。

主语从句后的谓语动词一般用单数形式。

常用句型如下：（1）It + be + 名词+ that从句（2）It + be + 形容词+ that从句（3）It + be + 动词的过去分词+ that从句（4）It + 不及物动词+ that 从句另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时，谓语动词要用虚拟语气“(should) +do”，常用的句型有：It is necessary (important, natural, strange, etc.) that …It is a pity (a shame, no wonder, etc.) that…It is suggested (requested, proposed, desired, etc.) that…宾语从句由连接词that引导宾语从句时，that在句中不担任任何成分，在口语或非正式的文体中常被省去，但如从句是并列句时,第二个分句前的that不可省。

例如：注意：在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后，宾语从句常用“（should）+ 动词原形”。

例如：I insist that she (should) do her work alone. 我坚持要她自己工作。

The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。

同位语从句同位语从句说明其前面的名词的具体内容。

同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。

例如：The news that we won the game is exciting.我们赢得这场比赛的消息令人激动。

I have no idea when he will come back home. 我不知道他什么时候回来。

The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。

同位语从句和定语从句的区别：that作为关系代词，可以引导定语从句，充当句子成分，在从句中作宾语时可以省略；that引导同位语从句时，起连词的作用，没有实际意义，不充当句子成分，一般不能省略。

试比较下面两个例句:I had no idea that you were here．（that引导同位语从句，不能省略）Have you got the idea（that）this book gives you of life in ancient Greece？（that引导定语从句，作宾语，可以省略）名词性从句专项练习100题1.
