状语从句的简化
状语从句的省略
状语从句同时具备下列两个条件:①主句和从句的主语一致，或从句主语为it；②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如：
When
(
the
museum
is
)
completed
,
the
museum
will
be
open
to
the
public
next
year
.
He’ll
go
to
the
seaside
for
his
holiday
if
(it
is
)
possible.
另外，比较状语从句经常省略。例如：
I’m
taller
than
he
(is
tall
).
The
higher
the
temperature
(is),
the
greater
the
pressure
(is
).
就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。
状
语从句的"简化"现象常存在于以下五种状语从句中:①由if,
unless等引导的条件状语从句;②由although,
though,
even
if
/
though等引导的让步状语从句;③由when,
while,
as,
before,
after,
until
/
till等引导的时间状语从句;④由as,
as
if等引导的方式状语从句;⑤由as,
than等引导的比较状语从句。下面针对这五种情形作一归纳。
(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:
If
(it
is)
possible,
he
will
help
you
out
of
the
difficulty.如果可能的话,他会帮你摆脱困境。
You
must
attend
the
meeting
unless
(it
is)
inconvenient
to
you.除非情况对你来说不方便,否则你必须出席这次会议。
(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:
a.连词+形容词
As
(he
was)
young,
he
learned
how
to
ride
a
bike.他小时候就学会了骑自行车。
Whenever
(she
is)
free,
she
often
goes
shopping.她有空就去逛商店。
Work
hard
when
(you
are)
young,
or
you'll
regret.少壮不努力,老大徒伤悲。
b.连词+名词
While
(he
was)
a
young
boy,
he
was
always
ready
to
help
others.他在孩提时代就乐于助人。
Although
(he
was)
a
farmer,
now
he
is
a
famous
director.尽管他曾是个农民,而现在是位著名的导演了。
c.连词+现在分词
As
(she
was)
walking
along
the
river
bank,
she
was
singing
a
pop
song.她沿着河堤边走边唱着流行歌曲。
Although
(he
is)
doing
his
best
in
maths
these
days,
he
has
still
got
no
good
marks.尽管近来他一直在学数学,但他仍然没有取得好成绩。
d.连词+过去分词
He
won't
go
there
with
us
unless
(he
is)
invited.除非受到邀请,否则他不会和我们一道去那里。
The
concert
was
a
great
success
than
(it
was)
expected.这场音乐会出乎意料地取得了巨大成功。
e.连词+不定式
He
stood
up
as
if
(he
were)
to
say
something.当时他站起来好像要说什么。He
wouldn't
solve
the
problem
even
if
(he
were)
to
take
charge.即使他来负责,他也解决不了这个问题。f.
连词+介词短语
She
looked
anxious
as
though
(she
was)
in
trouble.她看上去很焦急,好像遇到了麻烦。
He
had
mastered
the
English
language
before
(he
was)
in
the
USA.他到美国之前就懂英语了。
注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达。例如:
When
the
meeting
was
over,
all
the
people
went
out
of
the
meeting-room.当会议结束时,人们都走出了会议室。(=The
