Gone are the days _______ we spent together in the mountainous village.
A. whenB. thatC. where D. on which

Answer 1

为你解答。
Gone are the days （B.that） we spent together in the mountainous village.
句意：我们一起在这个山村度过的日子一去不返了。
解释：这一空要填定语从句的引导词，它在从句中是充当spent的宾语（即spend the days），要用that来表示the days。

Answer 2

选 B that
因为先行词是 the days，定语从句的宾语，所以 when，where，都不行。which 可以，但是不能带介词。
