由as,
which
引导的非限定性定语从句,as和which可代整个主句,相当于and
this或and
that。
区别:
1、as可位于主句的前、中(做插入成分)、后,译为“正如”。
which只能在主句中、后,一般不译。
as
we
all
know
,
he
never
smokes
.
正如我们所知,他从不吸烟。
2、如果从句是否定句,则只能用“which”引导。
3、非限定性定语从句中出现expect
,
think
,
suppose
等表示猜测、想象、预料等时,只能用as
she
succeeded
in
her
doing
the
research
work
,
as
we
expected
.
4、固定搭配:such/the
same+as

as与which引导非限制性定语从句的区别:
这类定语从句只能由
which
或
as
引导。两者之间的区别在于:
1.
which
引导的定语从句只能位于主句后,但as引导的从句可位于主句前、中、后。如:
David,
as
you
know,
is
a
photograopher.
戴维是个摄影师,你是知道的。(不可用which)
Li
Ming
is
late,
as
is
often
the
case.
李明迟到了,这事是经常发生的。(不可用which)
2.
as在定语从句中作主语时,从句谓语通常要有be或别的系动词,但which不受此限制。如:
Li
Ming
was
late,
which
(=and
this)
made
Mr.
Zhang
very
angry.
李明迟到了,这件事使张先生非常生气。(不可用as)
3.
as
引导的定语从句只表示一个众所周知或意料之中的事,但
which
不受此限制。如:
He
married
her,
which
was
unexpected.
他和她结婚了,这是出乎意料的。(不可用as)
4.
as有“正如”之意,而which则意为“这(件事,一点)”,可用and
this/that/it来代替。
5.
as多用于固定搭配中:as
is
often
the
case(这是常有的事),as
was
expected(不出所料),as
often
happens(正如经常发生的那样),as
is
known
to
all(众所周知),as
has
been
said
before(如上所述),as
is
mentioned
above(正如上面所提到的)等。
注:which
代表整个句子,还可用于in
which
case,
at
which
point,
on
which
occasion等。如:
I
may
have
to
work
late,
in
which
case
I’ll
telephone
you.
我可能得晚点下班,那样我会给你打电话的。
