1个回答

先给这句子加几个缺少的逗号:

Antarcitic,about which we know very little,is covered with thick ice all the year.

你看看,一加了逗号,答案是不是很清楚了?

about which we know very little 其实是

which we know very little about 的倒装.

也就是说,句子的“正常”形式是

Antarcitic,which we know very little about,is covered with thick ice all the year.

显然,以 where 替代 about which 是不行的.
