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

D.know about something
where引导状语从句。

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。

where是做地点状语的,从句中不缺地点状语。

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

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.
