高考中as的用法小结
as的用法小结
as可以作连词、介词及关系代词。现将其用法小结如下:
一、 as作连词的用法:
1. 作"当……的时候",引导时间状语从句。注意与when、 while的用法区别。
① when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。如:
When he was at college, he could speak several foreign languages.
When the clock struck twelve, all the lights in the street went out.
② while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动
词同时发生。如:
Work while you work. Play while you play.
③ 但属下列情形时,只用as, 而不用when或while。
A) 用于表示同一个人的两种动作交替进行,指"一边……,一边……"。如:
The girl dances as she sings on the stage.
He looked behind from time to time as he went forward.
B)表示两个同步发展的动作或行为,译为"随着……"。如:
As time went on / by, she became more and more worried.
As children get older, they become more and more interested in the things around
them.
C)表示两个短促行为或事件几乎同时发生。如:
I thought of it just as you opened your mouth.
Just as the flying worm hit her face, she gave a loud cry.
D) 后接名词表示某一年龄段时,用as。如:
As a young man, he was active in sports.
2. as=since, 作"既然"、"由于"解,引导原因状语从句,常用来表示已为人们所知
或显而易见的原因或理由。如:
As / Since you're not feeling well, you may stay at home.
As he wasn't ready in time, we went without him.
3. as=in the way that, 作"像"、"按照……的方式"解,引导方式状语从句。如:
He speaks English as Americans do.
Remember, you must do everything as I do.
4. 用于as...as...或not so/ as...as...中,前一个as是副词,后一个as是连词,引导比
较状语从句。如:
They helped the old man as often as possible.
I don't speak English so/ as well as he does.
5. 作"虽然"、"尽管"解,引导让步状语从句。常用倒装语序,即adj. /adv. / n.+ as
+主语+谓语+主句。如:
Tired as they were, they walked on.
Child as he is, he knows a lot. (child前不用冠词)
二、 as作关系代词,引导定语从句,作"正如"、"这一点"解。如:
He is very careful, as his work shows.
As is well-known, Taiwan belongs to China.
as的这种用法,请看2001年的高考题:
is known to everybody, the moon travels round the earth once every month.
A. It B. As C. That D. What
字母下划横线的为正确答案)
另外,当先行词被the same, such等词修饰时,常用as来引导定语从句。如:
Such a clever boy as he can learn anything quickly.
I was reading the same book as he bought yesterday.
三、 as作介词的用法:
as引导的介词短语大多用作状语,as译为"作为";少数情况可引起宾语补足语。
如:
As a League member, I'll take the lead in everything. (状语)
She works as a doctor. (状语)
They have me as one of their own children.(引起宾语补足语)
从一道高考题探究as的用法
从一道高考题探究as的用法请先看下面一道高考题：There is no simple answer, ______is often the case in science.（2013年山东高考卷）A. asB. thatC. whenD. where分析：答案A。
句意：正如科学研究中经常出现的情况那样，没有简单的答案。
分析句子结构可知：该题为非限制情定语从句，所填的词在句中作主语。
That不能引导定语从句，when 和where不能做主语，所以选as。
As is often the case…..意为：正如经常出现的情况那样……。
as 一词在英语中被广泛运用，也是全国各地高考命题的热点词之一，因些掌握该词用法很重要。
下面结合历届高考题将as的用法做一总结性归纳。

同……一样；一样Tom runs fast, but I run just as fast.汤姆跑得快，但我和他跑得一样快。
He can’t be as careful as his sister, Tom.他不能像他的姐姐那样细心。
（第一个as是副词，第二个是连词。
）二、用作介词作为……He works as a teacher. 他是老师。
如同……一样This room serves as a reading room.This book served him as a grammar book.三、用作代词as 多用作关系代词，引导限制性定从句和非限制性定语从句，常用以下结构：the same …as….；as…as….. such …as …；so …as ….；as is known to all; as we expect; as we know; as is well known; as is expected 等等。
I haven’t so much money as you want.我没有你想要的那么多的钱。

今天我们就一起来总结归纳一下它的众多用法，希望大家能在阅读后有那么一点点豁然开朗的感觉。
我们先来看一幅图，相信很多同学都会想起来这是出自哪部电影。
没错，正是《阿甘正传》。
这部电影里出现了很多经典台词，比如大家耳熟能详的“Life was like a box of chocolate,you never know what you’re gonna get. ”。
但今天我们想说的是另外一句。
这句话里就出现了AS这个字，那么大家知道在这句话里面as怎么翻译，又是什么词性呢？我们先来总结一下as的各种用法，相信学习后同学们自己就能解答这个问题了。
我们按照as在句中词性的不同划分用法。
