英语
as
的用法总结
一、用作连词的
as
1.
引导时间状语从句，
表示
“当……的时候”<
/p>
，
其用法与
when
和
while
类似。例如：
As
a child (When he was a child), she was sent to
six different schools.
此用法中
as
多表示从句与主句动作同时进
行，意为
“一边……一边……”
，一般不与状态动词连用。例如：
She
sang songs as she did her homework.
as
还
可以表示一动作紧接着另一动作发生，说明另一动作的结
果，有“随着……”的含义。例
如：
As time went by, we found he
was an honest man./As he grew older, he
lost interest in
everything except
gardening.
例
1
It
wasn
’
t
until
nearly
a
month
later________
I
received
the
manager
’
s reply.
A. since B.
when C. as D. that
解析：
本题的
as
中与
when
一起作为干扰项，
容易使考生往时间状语
从句上思考，事实上本
题是强调句，正确选项是
D
。
2.
引导原因状语从句，表示“由
于，因为”
，相当于
because,
但通
常置于句首。例如：
As he
is a qualified doctor, I trust his
advice on medical matters.
例
2
_____
modeling
business
is
by
no
means
easy
to
get
into,
the good model
will always be in demand.
A. While B. Since C. As D. If
解析：
本
题中
as
干扰性很强，
很多考生误以为
是原因状语从句，
但仔细分析不难发现正确答案应是
A
（
while
表示“只要”
）
。
3.
引
导让步状语从句，通常可与
although
或
though
通用，但语序
不同，
although
或
though
用于句首，
as
用于倒装结构。
例如：
Young
as
I
am,
I
already
know
what
career
I
want
to
follow.
/Although
（或
Though
）
I am
young, I already know what career I want to
follow. as
表示让步用于倒装结构，通常将从句的
表语、状语或动
词前置。如果表语有冠词
a/an,
需去掉。例如：
Great
scholar
as
he
is,
he
is
lacking
in
common
sense./Much
as
I
like
you,
I
couldn
’
t live
with you.
例
3 _____ he has limited
technical knowledge, the older
worker
has a lot of experience.
A. SinceB. Unless C. As D. Although
解析：
as
虽然有引导让步状语从句
用法，
但本题不是倒装结构，
故正确答案应是
< br>D
。
4.
引
导方式状语从句，表示“如，像”
。例如：
When
in
Rome,
do
as
Romans do./Do to others
as you would have others do to you.
例
4
We
wanted
to
get
home
before
dark,
but
it
didn
’
t
quite
________ as planned.
A. make outB. turn out C.
go onD. come up
解析：本题考查动词词组辨析，题干中的“
as
planned
”给同学
们提供了重要信息，答案选
B
。
5.
固定句型：
“主句，
as
+be/do+
主语”表示“也一样”
。例如：<
/p>
She
’
s unusually
tall, as are both her
parents./He
’
s a doctor, as
was his wife before she had children.
二、用作介词的
as
1.
表示“如，像”
。例如：
They got
united as one man./She spoke
of me as
her dearest friend.
2.
表示“作为
