关于定语从句的小问题~~

Question

（错） This is the mountain village where I visited last year.
（错） I will never forget the days when I spent in the countryside.
（对） This is the mountain village (which) I visited last year.
（对） I'll never forget the days (which) I spent in the countryside.

分析一下为什么错

Answer 1

第一句的visit是及物动词 所以先行词village在定语从句中做宾语。故不能用关系副词where来引导。只能用关系代词that或which.
第二句也是同样的道理，spend是及物动词，所以应该使用关系代词。
p.s 不要一看到表示时间的名词做先行词就用when引导，一看到地点名词就用where，关键看先行词在定语从句中做什么成分。试区别：
This is the room where they live.
This is the room which they visit.

Answer 3

从句中动词如果是及物的 就该有宾语的 作宾语的关系词当然是关系代词which 或that 了。（指物）
