The fact
  名词性从句是在复合句中起名词作用的从句,故其功能相当于名词,在复合句中能充当主语、宾语、表语、同位语等,因此根据它在句中的不同语法功能,名词性从句又可分为以下几个种类:
分类 语法功能
主语从句 在复合句中作主语;有时可用it作形式主语,而把主语从句放在句末
宾语从句 作及物动词、介词的宾语;有时可用it作形式宾语,而把宾语从句放在句末
表语从句 位于系动词之后作表语
同位 语从句 在复合句中作某一名词的同位语,说明其内容,一般紧跟在该名词之后
一、that、whether/if、as if/though和because引导的名词性从句
1.that引导的名词性从句
  that在名词性从句中不作任何成分,本身无意义,可引导所有的名词性从句。that 引导主语从句、表语从句和同位语从句时通常不能省略,引导宾语从句时通常可以省略。
2.whether/if引导的名词性从句
(1)whether和if本身有意义,意为“是否”,在从句中不充当句子成分。whether可引导所有的名词性从句,if主要引导宾语从句或不在句首的主语从句。
(2)whether与 if引导名词性从句时大多数情况下可以互换,但下列情况下只能用whether:
①后面直接跟or not时;②位于介词后引导宾语从句时。
3.as if/though、because引导的名词性从句
  as if/though、because在从句中不作任何句子成分,分别意为“因为”“好像”。
(1)as if/though主要置于系动词look、 seem、 sound、 be、 become等后面引导表语从句。
(2)because主要置于be动词之后引导表语从句。
二、连接代词引导的名词性从句
连接代词 用法
what 意为“什么;……的事物”,在名词性从句中作主语、宾语、表语或定语
whatever 意为“任何(事物)”,相当于anything that,在名词性从句中作主语、宾语或定语
who 意为“谁”,在名词性从句中作主语、宾语或表语
whoever 意为“任何人”,相当于anyone who,在名词性从句中作主语或宾语
连接代词 用法
whom 意为“谁”,在名词性从句中作宾语
whomever 意为“无论谁”,在名词性从句中作宾语
whose 意为“谁的”,在名词性从句中主要作定语,表示所属关系
which 意为“哪一个”,在名词性从句中可作主语、宾语、表语或定语,表示有范围的选择
whichever 意为“无论哪个”,在名词性从句中可作主语、宾语或定语,表示有范围的选择
三、连接副词引导的名词性从句
  引导名词性从句的连接副词有when、 whenever、 where、 wherever、 why、 how等,均在从句中作状语。
四、it代替名词性从句
1.it作形式主语,代替主语从句
(1)It+be+形容词+从句.;
(2)It+be+名词(词组)+从句.;
(3)It+be+过去分词+从句.;
(4)It+不及物动词(短语)(seem、 appear、 occur to sb.、happen等)+从句.
2.it作形式宾语,代替宾语从句
(1)sb. find/feel/think/consider/make/believe+it+宾语补足语(形容词或名词)+从句.;
(2)sb. like/dislike/hate/appreciate/enjoy+it+从句.;
(3)sb. see to/depend on/rely on+it+从句.;
(4)sb. take it for granted/owe it to ...+从句.
