定语从句的of which in which on which怎么用

in
which,
of
which,
on
which的不同用法
　　1)这些都是定语从句里面，由which引导的定语从句，介词提前。下面这些介词的使用除了意思上的区别，具体是要以which引导的从句而定的。
　　①in
which可以翻译成在……里面
　　The
school
(that/which)
he
once
studied
in
is
very
famous.
　　=
The
school
in
which
he
once
studied
is
very
famous.
　　②of
which可以翻译成是……的
　　Tomorrow
I
will
bring
here
a
magazine
(that/which)
you
asked
of.
　　=
Tomorrow
I
will
bring
here
a
magazine
of
which
you
asked.
　　③on
which可以翻译成在……的上面，或具体时间的某一天
　　I
have
a
dresser
in
my
bedroom,
which
there
are
many
cosmetics
on.
　　=
I
have
a
dresser
in
my
bedroom
on
which
there
are
many
cosmetics.
　　2)当然第一点只是介词作为基本意思的用法，还有一些固定搭配，得具体情况具体分析。

主要是看后面状语的搭配

比如，i
live
in
guangdong,in
which(=where)
crops
grow
here.

这里后面的意思应该是，crops
grow
in
guangdong
,所以用in（地点）

i
caught
the
bus
,on
which
i
met
my
teacher.

这里后面的意思应该是i
met
my
teacher
on
the
bus,所以用on（地点）

i
like
,by
which
i
improve
my
english

这里应该是
i
improve
my
english
by
reading
english.所以用by（方式）

i
like
skiing,from
which
i
can
get
a
lot
of
happiness.

这里是
i
can
get
a
lot
of
happiness
from
skiing。所以用from

做这种题，你先看看后面那个从句里要搭配什么样的介词，做熟了就容易了。
