Question

I’ll never forget the days ______ we spent together in the country.

32.I’ll never forget the days ______ we spent together in the country.
A. which B. on which C. when D, on that
为什么不是b，要解释

Answer 1

很简单，因为先行词the days在从句中当spent的宾语，当宾语时，关系代词只能选that或which或省略。只有先行词在从句中当时间状语时，才用when或on which/in which等。

Answer 2

这是个定语从句哈
which 连接代词（在从句中充当主宾表） when：连接副词（不充当主宾表，所以从句必须完整） on which(介词+n = 形容词/ 副词)
连接词的选择是看从句，we spent together in the country ：we 主语，spent谓语，缺了宾语，所以要选择连接代词 which

Answer 3

A. which (用作关系代词)后接定语从句

I’ll never forget the days which we spent together in the country
我永远不会忘记我们在乡下一起度过的日子

Answer 4

A. which (用作关系代词)后接定语从句I’ll never forget the days which we spent together in the country.this days 作宾语当然要选which连接代词啦。
求赞

Answer 5

选【A】--定语从句，可改为两句话
I’ll never forget the days.
We spent these days together in the country.
these days 作宾语，所以用关系代词which
