问题描述：
Antarctic _______ we know very little is covered with thick ice all the year round.A.whi
Antarctic _______ we know very little is covered with thick ice all the year round.
A.which B.where C.that D.about which
为什么不能用where答案C
答
因为定语从句里面的know是个及物动词，所以要给个能做宾语的引导词。
答
we know very little是用来修饰 Antarctic的，where 在句子中不是用来表示动作发生的地点。所以不能用where. 看这个句子：It was in the train station where we met.
答
we know very little 是插入语擦掉
紧接is 观察发现缺主语 用that充当主语
答
D.know about something
where引导状语从句。
答
本题答案选D
因为从句中缺乏宾语成分,需要关系代词充当宾语
know about是固定词组
答
where是做地点状语的，从句中不缺地点状语。
