在定语从句中 可以用介词加关系副词引导吗

Question

THANK YOU!关键是这个句子该怎样理解和分析！天呐！应该填什么

Answer 1

不能用介词+关系副词。 可以用介词+which=关系副词
介词+which可以代替when ，where，why等
I will never forget the days on which（when）we studied together.我永远忘不了我们一起学习的日子。
This is the town in which(where) Shakespeare was born.这就是莎士比亚出生的城镇。

（至于用什么介词需要看定语从句中动词或形容词的习惯搭配来确定）

Answer 2

万万不行。 多数情况下，介词+关系代词=关系副词。
The school in which I studied is very famous now.
=The school where I studied is very famous now.

Answer 3

不能那样引导。但你说的这个题我见过，它属于介词后的宾语从句。

Answer 4

from where不是定语从句，是from（介词）后面加where引导的宾语从句再做状语，好复杂啊，呵呵 ，例如
He was standing at the top, from where he could see it clearly
补充：不是宾语从句，是状语啊，他站在顶部，从那里他可以看得更清楚

Answer 5

可以、
例如 Frank's dream was to have his own shop in which to produce the workings of his own hands.

括号里填 in which
