例如:It is unknown whether he will come (他是否会来还不知道。
)二、宾语从句宾语从句在句中充当宾语。

因此选A。
【点评】考查名词性从句,本题涉及that引导的主语从句和what引导的宾语从句。

名词性从句知识点
名词性从句1.概念:在从句中做主语/宾语/表语/起解释说明的作用(同位语)。
或者说是起名词作用的从句。
名词性从句一律用陈述语序。
2.分类:主语从句/宾语从句/表语从句/同位语从句3.连接词:⑴连接代词(who谁,主格;whom谁,宾格;whose谁的,所有格;what什么,which哪一个,whatever无论什么,whichever无论哪个,whoever无论谁);⑵连接副词:when,where,how,why,⑶由if/whether引导,在句中意为“是否”。
用法:①句子成分完整,用that;②成分完整,意思不完整,用whether/if(是否),连接副词(when/where/why/how)/+ever;③成分不完整:指人用who(主/宾)whom(宾)whoever(主/宾)whomever(宾);指物:用what(主/宾)。
4.详解:⑴主语从句:用来充当整句话的主语。
①主语从句在复合句中作主语的名词性从句,通常放在主句谓语动词之前。
that在从句中只起连接词作用且不可省略。
Whether she will come to the party is uncertain.A.陈述句做主语从句的转化方式,用that 引导。
The earth goes around the sun.=That the earth goes around the sun is a fact.B.一般疑问句转化为主语从句,只能用whether来引导,不能用if。
一般疑问句语序转化为陈述语序。
Will it rain tomorrow?=Whether it will rain tomorrow is not know.C.特殊疑问句变为主语从句,还是用原来的疑问词引导(特殊疑问句有两种结构,一种是疑问词+一般疑问句;另一种是特殊疑问句本身就是陈述结构)What does she want?=What she wants is a trip to Lijing.她想要的是去丽江旅行。
