Question

where引导地点状语从句和定语从句的区别

Answer 1

1.
where引导定语从句时,
where是关系副词,
在从句中作地点状语,
其前面有表示地点的先行词,
where引导的从句修饰先行词。
eg：
The
store
where
I
bought
this
pen
is
not
far
from
here.
2.
where引导状语从句时,
where是从属连词,
where引导的从句修饰主句的谓语动词,
where前面没有表示地点的先行词。eg:
I
found
my
books
where
I
had
left
them.
有时,
where引导的地点状语从句兼有抽象条件含义,
可放在主句的前面,
而where引导的定语从句则不能。例如:
Where
there
is
a
will,
there
is
a
way.
〔谚语〕有志者事竟成。、
3.
在有些情况下,
where引导的定语从句可转换为where引导的地点状语从句。eg:
A
tall
building
was
put
up
at
the
place
where
there
used
to
be
a
desert.
（＝A
tall
building
was
put
up
where
there
used
to
be
a
desert.
）在以前曾是沙漠的地方盖起了一幢高楼。
