定语从句中何时能用介词+which代替when,where,whose,why?

一般来说关系副词=介词+关系代词
如：why=for which
where=to which
when=during which
whose=of which
具体加什么介词，视情况而定。
1句中，用on比较好：4句中，用during比较好。
当定语从句所修饰的先行词是表示时间的名词时，用when，在定语从句中充当时间状语。在口语中可以用that代替when，也可以用介词+which来代替when。
当定语从句修饰表示地点的名词时，用where，在定语从句中充当地点状语从句。
当定语从句所修饰的词是表示原因的词，用why，在定语从句中作原因状语。
当定语从句先行词与从句中某个名词有所属关系，表达“……的”意思时，用关系代词whose 引导定语从句，它既可以指代人，也可以指代物。指物时用of which，指人时用of whom。

在定语从句中
1、关系代词：who, whom, which, that, whose
指人：who, whom, whose, that
指物：which, that,whose
2、关系副词：when,where,why

★当从句的句子完整时，用关系副词：
当从句的句子不完整时，用关系代词
（关系代词+介词=关系副词）

作主语，先行词是人用who/that
先行词是物用which/that
eg.一个男孩a boy
一个能讲三国语言的男孩the boy who/that can speak three foreign languages
一扇门a door
一扇木制的门the door which/taht is made of wood

作宾语，先行词是人用whom/that(who)
先行词是物用which/that
eg.一个女孩a girl
一个警察正在找的女孩the girl whom/that the police are looking for
一把钥匙a key
一把我昨天弄丢了的钥匙the key which/that I lost yesterday

whose 作定语，先行词可以使人，也可以是物,形式为whose + n.
一位学生a student
一位母亲生病的学生the student whose mother is ill
一个房子a house
一个窗子面朝南的房子the house whose windows face south

eg.I saw a tree. Its leaves were black.
→I saw a tree whose leaves were black.
=I saw a tree of which the leaves were black.
先行词指人：
whose + n. =the + n.+ of whom(或of whom + the + n.)
先行词指物：
whose + n. =the + n.+ of which（或of which.+ the + n.)
