一、概述:
在句子中起名词作用的各种从句统称为名词性从句。
根据它们在句中的语法作用,这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。
而在复合句中充当主语的句子叫做主语从句.
二.主语从句主要分类:
(1)由连词that引导的主语从句:
引导词that无含义/在句中不做成分/不可以省。
例如:
Thatyouwillwinthemedalseemsunlikely.
Thatyouaresoindifferentbothersme.
Thatshesurvivedtheaccidentisamiracle.
(2)用连词whether引导的主语从句:
whether有含义(是否)/在句中不做成分/不可以省。
注意:
引导主语从句,不能用if,只能用whether。
例如:
Whetherwewillholdapartyintheopenairtomorrowdependsontheweather.
Whethersheiscomingornotdoesn’tmattertoomuch.
(3)用连接代词引导的主语从句
在由连接代词who,whose,whom,which,what,whoever,whomever,whichever,whatever引导的名词性从句中,
其连接代词在句中起名词性作用,担当一定成分.
Whatyouneedismorepractice.
WhatIwanttoknowisthis.
Whateverwedoistoservethepeople.
注:
whatever/whoever的功用
whatever,whoever在主语从句中不含疑问意义。
它引导主语从句,并在从句中作主语、宾语、表语等。
whatever=anythingthat;
whoever=anyonewho。
要注意和whatever,whoever引导的让步状语从句的区别。
如:
Whoeverbreaksthelawshouldbepunished.(主语从句)
(=Anyonewhobreaksthelawshouldbepunished.)
Whoeverbreaksthelaw,heshouldbepunished.(让步状语从句)
(=Nomatterwhobreaksthelaw,heshouldbepunished.)
(4)用连接副词when,where,why,how引导的名词性从句(其连接副词有含义,在句中作状语。
)
例如:
Whereweshouldleaveitisaproblem.
Whentheywillcomehasn’tbeenmadepubic.

it构成的主语从句
(1)由连词that引导的主语从句,在大多数情况下会放到句子的后面,而用代词it作形式主语。
Thatlighttravelsinstraightlinesisknowntoall.
=Itisknowntoallthatlighttravelsinstraightlines.
Whentheplaneistotakeoffhasnotbeenannounced.
=Ithasnotbeenannouncedwhentheplaneistotakeoff.
(但当what引导的主语从句表示“…的东西”时,一般不用it作形式主语。
错:
Itisabookwhathewants.
对:
Whathewantsisabook.
另外,需要注意的是,it作形式主语代替主语从句时,要注意和as引导的定语从句的区别。
试比较:
ItwasreportedthattheUSwasundertheterroristattack.
Aswasreported,theUSwasundertheterroristattack.
(2)常见用it作形式主语的复合句结构
