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)This film is as interesting as that one.这部电影和那部电影一样有趣。
(2)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。
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。
几个关于as...as的常见句型：
(1)as...as possible
Please answer my question as soon as possible.请尽快回答我的问题。
(2)as...as usual/before
She looks as pretty as before.她看起来和以前一样漂亮。
(3)as long as... (引导条件状语从句)
It took us as long as three years to carry out the plan.我们花了长达三年的时间才完成这项计划。
(4)as far as
He walked as far as the railway station yesterday evening.昨天傍晚，他一直散步到火车站。
(5)as well as
She cooks as well as her mother does.她烧菜烧得跟她母亲一样好。
一些带有as...as结构的常见短语归纳：
as busy as a bee像蜜蜂一样忙碌
as easy as ABC像ABC一样容易
as deep as a well像井一样深
as light as a feather像羽毛一样轻
as soft as butter像黄油一样软
as rich as a Jew像犹太人一样富裕
2. as用作连词引导时间状语从句
as与when，while都是引导时间状语从句的从属连词，含义都是"当……的时候"。但它们有区别：用when时，从句的动作可以与主句的动作同时发生，也可以先于主句的动作发生；用while时，从句的动作为一过程，主句动作与从句动作同时进行或在从句动作过程中发生；用as时，主句和从句的动作同时发生，具有延续的含义。例如：
(1)It was snowing when he arrived at the construction site.他到达工地时，天正在下雪。
(2)He was watching TV while his mother was cooking.他母亲做饭时他在看电视。
(3) You will grow wiser as you grow older.你会随着年龄的增长而越来越聪明。
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作连词引导让步状语从句
as与although (或though)，however (或no matter how)等都可以引导让步状语从句，含义是"虽然，尽管"，但它们有区别：although语气稍正式些，可放在句首，也可放在句中，主句中不能再用but，但可以用yet；as所表示的语气较强，引导的让步状语从句用倒装语序；however引导让步状语从句时，它的后面可跟形容词或副词，也要用倒装语序。例如：
(1) Although he is quite old, he still jogs every day.他虽然年纪相当大，仍然每天慢跑。
(2) Strange as it may seem, nobody was injured in the accident.这次意外虽然显得令人不可思议，却没有人受伤。
(3) However hard he may try, he will not attain his goal.无论他怎样努力也达不到目标。
二、as作关系代词的用法
关系代词as引导定语从句时，既可以单独使用，也可以与其他词连用，其用法要比that和which更为复杂。
1. 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。
2. 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)
三、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。
四、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。
as用法小结
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。
五）含as的固定词组的用法
1．as soon as作“一…就”解，引导时间状语从句。eg：
As soon as I get to Beijing，I'll write to you．我一到北京，就给你写信。
2．as／so long as作“只要”解，eg；
As／So long as you study hard，you'll make progress．只要你努力，你就会取得进步。
3．as if／though常用来引导方式状语从句，作“好像，仿佛”解。如果从句中讲的是非真实情况，则用虚拟语气。eg：
She loves the child as if／though he were her own．她爱这个孩子如同爱自己的孩子。
As if／though也可用来引导表语从句，常用在“It appears／looks／seems．．．+as if／though”句型结构中。eg；
It appears as if／though it is going to clear up．看起来天要晴了。
It seems as if／though he knew nothing about it.他好像对此事一无所知。
4．as to作“关于，至于”解。eg；
There is no doubt as to his honesty．他的诚实是无可置疑的。
5．as much／many as作“多达．．．”，“达到．．．之多”解。eg：
He can earn as much as 5000 dollars a month．他每月能挣5000美元。
6．so／as far as I know作“就我所知”解，在句中作插入语。eg：
As／So far as I know，he will come here next Monday．据我所知，他将于下星期一到这里来。
7．as a result，as a result of表示“由于．．．的结果”。eg：
She died as a direct result of the accident．她的死是那次事故的直接结果。
8，as well为“也，还”之意。eg：
Come early，and bring your brother as well．早点来，把你的弟弟也带来。
9．so as to，so．．．as to若跟动词原形，表示目的或结果。eg：
He studied hard so as to pass the exam．他努力学习以便通过考试。(表示目的)
as可以作连词、介词及关系代词。现将as的用法小结。如下：
1)作连词：
(1)作“当……的时候”解，引起时间状语从句，与while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。例如：
①As she sang, the tears ran down her cheeks.
她一边唱歌，一边流泪。
②I startled as he opened the door.
他一开门，我吓了一跳。
(2)作“因为”，“由于”解，引起原因状语从句，与because相近。例如：
①I 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。
②As Jim liked walking, we started off on foot.
因为吉姆喜欢走路，所以我们就步行出发了。
(3)作“如”，“像”解，引起方式状语从句，或比较状语从句。例如：
①You should do as the teacher tells you to do.
你应该像教师教你的那样去做。(方式状语)
②He speaks English just as Americans do.
他说英语就像美国人说英语一样。(方式状语)
③The weather was not so wet as it is today.
过去的天气不像现在这样潮湿。(比较状语)
④The Christmas tree is almost as tall as the room.
这棵圣诞树差不多同这间房子一般高。(比较状语)
▲另外，经常用在 as…as possible的结构中。例如：
⑤Read the story as quickly as possible.(” Read the story as quickly as you can.)尽快地阅读这篇故事。
⑥They watered the trees as often as possible. (”They watered the trees as often as they could.)
他们尽可能经常给树浇水。

(2)作“充当”，“作为”解。例如：
