as引导限定性定语从句做的成分
在定语从句里，as既可以引导非限定性定语从句，也可以引导限定性定语从句。
（1）非限定性定语从句：用法同which，用来指代前面的句子（而非先行词），多与know/expect/see搭配使用。
e.g.as
we
know,
smoking
does
harm
to
our
health.
另：which和as的区别
a.
which不能放句首（the
sun
heats
the
earth,
which
is
very
important
to
us.)
b.
as如果在从句中作主语，后面的谓语动词必须是系动词。(it
rained
hard
yesterday,
which
prevented
me
from
going
to
the
park.这边就不能用as来代替which，因为prevent是行为动词）
（2）as引导限定性定语从句，多与the
same/such/so搭配使用。
e.g.
i
have
got
into
the
same
trouble
as
he
has.
