At no time__forget the days __we spent together前面倒装用should we能理解后面为什么是which而不能用when呢
问题描述：
At no time__forget the days __we spent together
前面倒装用should we能理解
后面为什么是which而不能用when呢
答
At no time should we forget the days (which) we spent together.
days是spend的宾语 we spent the days
which 在这里也可以省略
答
因为spent要有宾语，这个时候只能用which
答
we spend days,days是spend的宾语,不是状语,所以不能用when
