Question

定语从句 关于AS与WHICH

The British are not familiar with difficult cultures and other ways of doing things,____is often the cases in other countries.
括号里填as,为什么呢?为什么又不可以填which呢?

Answer 1

这是非限制性定语从句，as做定语，先行词是前面的整个句子，你可以理解为“就像，正如”的意思

区别
1．As和which都可以在定语从句中做主语或者宾语，代表前面整个句子。
2. as 引导非限制性定语从句，可放在主句之前，或者主句之后，甚至可以切割一个主句；which引导的非限制性定语从句只能放在主句之后。
3. 当先行次受such, the same修饰时，常用as

就语法来说，这里用AS和which都可以。但是which的话句子的意思就不同了
用AS有正如，好像的意思。而which就只是代表者前面整个句子，译起来就不通了..

我记得这是以前高中经常考的一个点...只要记住AS有正如，就像的意思就可以轻易做对

Answer 2

此题只能选D，
不能选C。
因为定从作为插入部分位于句中了。
补充知识:
as和which都可引导非限制性定从,
指代上面或
下文
所说
的一件事,
因此,也可以说,
as或which就是指代整个
主句
.
其
区别
在于:
一.
位置上的差别:
which引导的定从只能放在主句之后,
用来指代
前面
所说的一件事;as引导的定从可位于主句之前,之中或之后,位置比较灵活.
因此,当位于主句之后时,有时两者是可以通用的.
如:
He
married
her
,
which/as
was
natural.
He
was
very
useful
to
me
,
which/as
I
realized
.
但位于句首或句中时,只能用as,
不能用which.
如:
As
I
realize,
he
was
very
useful
to
me.
This
machine,
as
might
be
expected
,
has
stopped
operating.
二.在
句法
上的区别(这个很重要):
1.as常用作一些
实意动词
(如see,
know,
hear,
watch,
remember,
say,
tell,
show,
expect,
guess等)的
宾语
，这
类动词
与as几乎成了一种固定搭配,且多用被动
形式
。
如:as
we
know,
as
is
known
to
us
all
,
as
is
expected,
as
is
shown,
as
is
said
,
as
follows,
as
we
can
see,
as
may
be
imagined,
as
often
happens,
as
has
been
said
before等.
Einstein,
as
we
know(=as
is
well
known),
is
a
famous
scientist.
众所周知，爱因斯坦是一位著名的科学家。
There
was
a
net
bar
around
here,
as
I
remember.
我记得这儿附近有一家网吧。
2.which一般用作实意动词的
主语
，这时它所引导的
从句
与主句
之间
常含有并列、
因果关系
。如:
I
bought
my
sister
a
doll,
which(=and
that)
delighted
her
greatly.
我给妹妹买了一个洋娃娃，这使她非常高兴。
The
boy
had
a
fever
every
night,
which
worried
his
parents
very
much.
这男孩每晚发烧，这使他父母非常焦急。
3.
当从句的
谓语动词
是否定形式或从句谓语动词带的是一个
复合宾语
结构
时，一般用which而不宜用as。如:
You
haven't
recognized
me,
which
I
didn’t
understand.
你居然没有认出我，我真不明白。
He
failed
in
the
exam,
which
I
find
quite
strange.
他考试没及格，我认为太奇怪了。
4.不能省去非
限制性定语从句
中的
be动词
时，用which
(反之则用as)。试比较:
Mary
told
me
she
passed
the
exam,
which
was
a
lie.
(was
不可省略)
As
(was)
planned,
we
met
at
the
airport.(可省略was)
