he doesn't know___is ___he was born.的答案及解释

he doesn't know_A__is ___he was born.
A. that where B. that what C. where that D. what where
“他不知道的事情就是 他是在哪出生的。”
he doesn't know that，
that is
where he was born 这是一个宾语从句。
原句子可以写成he doesn't know where he was born 。

know后面的that is where he was born是个宾语从句，that是代词“那”的意思。where he was born是is的表语。如果变成He doesn't know where he was born则是由where 引导的宾语从句。再变成He he doesn't know where it was he was born.则是强调结构“他不知道他究竟出生在哪儿”在名词性从句中what表示“所。。。的地方”放在句中则不通顺。

题目是错的

按照题目的想法应该是

what he doesnt know is where he was born

题目有没有抄错，如果答案是A的话是不是应该这么说：He doesn't know that where he was born .

可以把where转换成the place that理解。

这题考查两个知识点：一是宾语从句，因为that is where he was born这个句子做know的宾语；
二是主语从句where he was born 做前面宾语从句中的主语。 这个句子可以翻译成：他不知道那是他出生的地方。表示地方用where
