第十三章名词性从句
名词性从句用法讲解与专项练习题及答案
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。
高考常从连接词的选择、语序、语气、时态等方面来考查。
名词性从句中的连接词有连词that/whether/asif，连接代词what/who/which/whose/whatever/whoever/whomever/whichever，连接副词where/when/why/how/wherever/whenever。
第1讲引导名词性从句的连接词
考点1.引导名词性从句的连接词有哪些
有学生认为，引导同位语从句只能用that,这句话对吗？
先看下面几个句子。
①Ihavenoquestionthathewillcome.
②Ihaveaquestionwhetherhewillcome
③Ihaveaquestionwhenhewillcome.
我们可以看出：
上面三个句子中question后面都是同位语从句，都是说明question的内容的。
在句①中，同位语从句的原句是陈述句，由that引导；
在句②中，原句是一般疑问句，由whether引导；
在句③中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。
其实，所有名词性从句的连接词都有上面的三种情况。
宾语从句：
Idon’tknowthathewillcome.
Idon’tknowwhether/ifhewillcome.
Idon’tknowwhenhewillcome.
表语从句：
WhatIdon’tknowisthathewillcome.
WhatIdon’tknowiswhetherhewillcome.
WhatIdon’tknowiswhenhewillcome.
主语从句
Thathewillcomeisobvious.
Whetherhewillcomeisn’tknownyet.
Whenhewillcomeisn’tknownyet.

考点3.whether与if引导名词性从句时的区别
A.在主语从句、表语从句、同位语从句中只能用whether,不能用if。

Weoughttodiscusscarefullythequestionwhetherwecandoitornot.
B.在宾语从句中whether和if可以互换，但：
i.作介词宾语时连接词一般用whether。
如：
Italldependsonwhethertheywillcomeback.
ii.后面直接跟ornot时用whether。
如：
Ididn’tknowwhetherornothehadarrivedinWuhan.
C.whether也可与动词不定式连用，但if不能。
Ihavenotdecidedwhethertogoornot.
D.whether常与or连用表示一种选择，if不能这样用：
Thequestionofwhethertheyaremaleorfemaleisnotimportant.
E.whether可引导一个让步状语从句表示“不管”、“无论”，而if不能。
如：
Whetherhecomesornot,wewillbeginourpartyontime.
F.discuss后通常用whether。
