as只有作副词、介词、连词、代词等四大用法,具体用法如下:
一)as作副词,表示程度,意为“同样地”。在“as...as...”,“not as...as...”结构中的第一个as是副词,作“和/与...(不)一样”解。eg:
Jack is as tall as his father.杰克和他的父亲一样高。
He doesn't speak English as/so fluently as you.他的英语说得不如你流利。
二)as作介词。
1.作“如,像”解。eg:
They got united as one man.他们团结得像一个人一样。
2.作“充当,作为”解。eg:
As a writer,he was famous.作为作家,他是很有名的。
三)as作连词,常用来连接主句和状语从句。
1.引导时间状语从句,作“当...的时候”解,有“随着...”之意,与while意义相近,强调两个动作同时发生;或某事一发生,另一事立即发生。eg:
He shouted aloud as her ran along.他一边往前跑,一边高声地呼喊。
I was startled as he opened the door.他一开门,我吓了一跳。
as作连词,相当于when。eg;
As a little boy (When he was a little boy)he began to learn to play piano.他小时候就开始学弹钢琴。
2.引导原因状语从句,作“因为,由于”解,与because的用法相近。eg;
I must stop writing now,as I have rather a lot of work to do.我必须停笔了,因为我还有许多工作要做。
3.引导方式状语从句或比较状语从句,作“正如,(如)像”解。例eg:
As in your country,we grow wheat in the north and rice in the south.正如(像)你们国家一样,我们在北方种小麦,在南方种大米。(方式状语从句)
When at Rome,do as Romans do.入乡随俗。(方式状语从句)
4.引导让步状语从句,作“虽然,尽管”解。这时从句常用倒装语序,即把从句中的表语、状语或动词原形放在as之前。eg;
Strange as it may seem,it is true.尽管这事看上去很奇怪,但却是真的。
Try as he might,Tom could not get out of the difficulties.不管怎样努力,汤姆还是摆脱不了困境。
四)as作关系代词。
1.引导限制性定语从句,用在“such...as”,“the same...as”,“as...as”等结构中,常译作“像...一样的人(或物)”,“凡是...的人(或物)”。例eg:
He wished to be such a man as Lei Feng was.他曾希望做一个像雷锋那样的人。
My hometown is no longer the same as it was.我的家乡再也不像过去一样了。
2.引导非限制性定语从句,用来指代它前面的整个句子(即先行句),意思是“这一点”。这个分句可以位于句首、句中或句末。eg:
As is well known,oceans cover more than 70% of the earth.我们知道,海洋占地球面积的百分之七十以上。

一、as作连词的用法
1.as...as的用法
as...as意为"和……一样",表示同级的比较。使用时要注意第一个as为副词,第二个as为连词。其基本结构为:as+adj./adv.+as。例如:
(1)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。
(2)This film is as interesting as that one.这部电影和那部电影一样有趣。
其否定式为not as/so+adj./adv.+as。例如:
This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。
若有修饰成分,如twice,three times,half,a quarter等,则须置于第一个as之前。例如:
Your bag is twice as expensive as mine.你的袋子比我的贵一倍。
2、as引导时间状语从句
此时,as译作“当……时候”,可以放在主句之前,也可以放在主句之后。例如:
He smiled as he said goodbye to me.
他向我道别时微笑了一下。
As she was walking in the park,she heard a girl singing.
她在公园里散步时,听到一位女孩在唱歌。
I sang an English song as I went along the river.
我边沿河边走边唱英文歌。
3.as用作连词引导原因状语从句
as,because,since都可以表示因果关系,连接原因状语从句,含义是"因为,由于",但它们有区别:because表示的语气最强;as一般放在句首,语气较弱,较口语化;since常常用在书面语中,表示多为对方已知的、或稍加分析便可得知的原因,有时可译作"既然"。例如:
(1)He will succeed because he is in earnest.他一定会成功,因为他很认真。
(2)Since you are so sure of it he”ll believe you.既然你对此如此有把握,他会相信你的。
(3)As rain has fallen,the air is cooler.因为下过雨,空气比较清爽。
4、as引导让步状语从句
此时,as译作“尽管”。当as引导让步状语从句时,不把as放在从句的开头,而是将充当从句主要成分的形容词、副词、分词、动词原形或不加冠词的单数可数名词置于前面。
(1)将表语放在句首,再将as放在表语和主语之间。例如:
Child as he is,he knows quite a lot of things.
虽然他还是个孩子,但他懂得很多事情。
(2)将状语放在句首,再将as放在状语(副词)和主语之间。例如:
Much as she likes,she will not take it.
尽管非常喜欢它,但她也不会拿走的。
(3)将主动词放在句首,再将as放在主动词和主语之间。例如:
Try as he did,he didn’t succeed.
尽管他努力了,但还是没有成功。
二、as作介词的用法
as作介词,意思是"作为","以……身份"。例如:
He came to China as a tourist five years ago.他五年前以游客的身份来过中国。
三、as作副词的用法
to the same degree or amount;equally"相同地","同样地"。例如:
They don”t have as many airplanes.他们没有同样多的飞机。
四、as作关系代词的用法
as引导英语从句时,在从句中充当主语、宾语、介词宾语或表语,既可以指人,也可以指物。
1.as单独引导定语从句
as单独引导定语从句时,先行词可以是一个词,也可以是一个句子或短语。例如:
(1)She is late,as is often the case.她迟到了,这是经常的事。(先行词是整个主句)
(2)To shut your eyes to facts,as many of you do,is foolish.对事实视而不见--你们好多人都是如此的愚蠢。(先行词是不定式短语)
2.as引导定语从句与其他词连用
①用于the same...as结构中
This is the same book as I read last week.这本书和我上周读的那本是一样的。
②用于such...as结构中
I don”t like such books as he recommends.我不喜欢他推荐的那些书。
③用于"so+adj.+a/an+n.(单数)+as"结构中
I am not so strong a man as I was.我已经没有从前那么强壮了。
