她已再婚,这是意料中的事。 2.As anyone can see, We are tired. 我们累了,这是有目共睹的。
的比较，但要注意第一个as为副词，第二个as为连词。根据比较 对象和性质的不同又可以把此种结构分为三种： 一.“as…as…结构”用于表示不同人或物同一性质的比较，意
为“……和……一样……”。 eg. The tree is as tall as the building (is)．
这棵树和那栋楼一样高。 二.“as…as…结构”用于表示同一个人或物不同性质的比较，
as 引导方式状语从句 小结
as引导方式状语从句，意为“按照”、“依照”、“像” 。 1.Doctors have said that as many as 40 percent of patients
don’t take medicine as directed. 医生说多达40%的病人没有按照被指导的方式吃药。 2. As I explained on the phone, your request will be considered at the next meeting. 按照我在电话里解释的，你的要求在下次会议上考虑。

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。
一、用作副词,修饰形容词或副词。
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。
as使用及总结,高考英语知识素材积累
as 使用及总结，高考英语知识素材积累倍数词+as…as 是…的几倍他用功的程度是我的三倍He studies three times as hard as I.One and a half times as…as…是…的一倍半He is eight years old, and I am one and a half times old as he.他8岁，我12 岁。
More than+（倍数词+as…as…）是…的几倍还不止=倍数词+more than He studies three times harder than I.一、as…as 结构的差不多用法其差不多意思为“与……一样”，其中的第一个as副词，其后通常接形容词或副词(用原级)，第二个as可用作介词(后接名词或代词)或连词(后接从句)。
使用时应注意以下几点：He runs as fast as John ( runs fast)1. 在否定句中，第一个as 也可换成so：He doesn’t study as so hard as his brother. 他学习不如他弟弟努力。
2. 在该结构的两个as之间通常接形容词或副词的原级，但若涉及数量或程度，可用“as much+不可数名词+as”和“as many+可数名词复数+as”：You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。
I haven’t got as much money as I thought. 我不像原先想像的有那么多钱。
其间接形容词时，有时该形容词还可修饰另一名词，但那个名词应带有不定冠词(注意词序)：She is as good a cook as her mother. 她和她妈妈一样是位好厨师。
也可说：She is a cook as good as her mother.但不说：She is as a good cook as her mother. 或They are as g ood cooks as us.二、关于第二个as的词性第二个as后接从句时，该as通常为连词，但有时那个as还充当其后从句的主语或宾语，现在该as实为关系代词。

As的用法归纳
As的用法归纳as的用法很多，又比较复杂，本文就此作一归纳：一、作副词，意为“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。
二、作连词，1. 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:(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。
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。
例如:John was having his dinner when I saw him. 当我看到约翰的时候，他正在吃饭。
She can write only when the baby is asleep. 只有婴儿睡着的时候，她才能写作。
(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或在从句动作过程中发生。
例如:W e must strike while the iron is hot. 要趁热打铁。
While we were reading, the teacher came in. 我们正在读书的时候，老师走了进来。
(3). 但属下列情形时，只用as, 而不用when或while。
①用于表示同一个人的两种动作交替进行,指“一边……,一边……”。
例如:The girl dances as she sings on the stage.那个女孩在舞台边唱歌边跳舞。
He looked behind from time to time as he went forward. 当他朝前走时，不时地向后看。
②表示两个同步发展的动作或行为,译为“随着……”。
例如:As time went on / by, she became more and more worried. 随着时间的流逝，她变得越来越焦虑。
浅谈as的高频考点
浅谈as的高频考点摘要as是英语中为数不多的可以充当各种词性且意义纷繁复杂的词之一,是英语教学中的难点,也是各类考试的热点,本文从语用角度对as的高频考点进行归纳,旨在使学生熟练掌握as的考路和解题技巧。
关键词 as用法高频状语从句定语从句高考As有多种词性和意思,用法也涉及到定语、状语从句等多个重要语法,因此熟练掌握as的各种用法和解题技巧,在各级各类考试中都是得分的关键,以下是几个as的高频考点。
一、as...as的用法as...as意为“和……一样”,表示同级的比较。

(二)as well as的使用频率很高,用途非常广泛。

如:Living things need air and sunlight as well as water.(连接名词)She is a talented musician as well as being a photographer.(连接动名词)The child is lively as well as healthy.(连接形容词)He calculates the mass of materials before, as well as after experiments.(连接介词短语)注意:as well as连接的虽然是两个并列成分,但强调的重点在前面,不在后面。

例析历年高考试题归结as难点用法河南谢奎金来源：2009 年上半年《试题与研究》单词as词形简单，但用法复杂，可作副词、替代词、关系代词、从属连词和介词。
还可与其他词汇结合构成诸多搭配，故as一直是高考热点，也是广大考生复习备考的难点。
现结合考题，剖析难点，以飨读者。
一、用作介词，as与like用法区别[例1] Let’s learn to use the problem we are facing ______ a stepping-stone to future success.( NMET 2008全国卷)A. toB. forC. asD. by[解析] C。
as作介词表“作为”，常接在treat/regard/recognize/use等动词之后；而like表“像……一样”。
试比较：(1)He is a child, and must be treated as such.他年幼，应该当孩子对待。
(2)He acted like a child, while he had grown up.他虽已成人，但做事却像孩子一样。
二、用作从属连词1．表时间，as/when/while用法区别[例2] Mother was worried because little Alice was ill, especially ______ Father was away in France. (NMET 1994全国卷)A. asB. thatC. duringD. if[解析] A。
主从句动作先后发生常用when；两个较长动作同时发生用while；特别强调主从句动作同时发生用as，译作“一边……一边”，as还可表“随着”。
另when, while还可用作并列连词。
when表at that time，而while表“两相对照”。
2．表原因，as/because/since/for用法区别[例3] Jenny was very sad over the loss of the photos she had shot at Canada, ______ this was a memory she especially treasured. (NMET 2006广东卷)A. asB. ifC. whenD. where[解析]A。
as 作从属连词引导原因状语从句。
as和because, since, for的区别是：because 语势最强，用来说明人所未知的原因，回答why提出的问题，可置于强调句中且其前可加修饰语；since是双方都知晓原因或经过分析而得之的原因，语气次之；for是并列连词，前用逗号隔开，表逻辑推理或补充说明；as语气最弱，原因是显而易见的或已为人们所知，即已知原因，所引导的分句可置于句首。
3．表转折，引导让步状语从句[例4] ______, he talks a lot about his favorite singers after class. (NMET 2005重庆卷）A. A quiet student as he may beB. Quiet student as he may beC. Be a quiet student as he mayD. Quiet as he may be a student[解析] B。
as 引导让步状语从句时，形容词、副词、动词等常置前；若表语为名词，前置时使用零冠词；从句谓语动词常和助动词或情态动词may, might, will, would等连用。
4．表正如，引导方式状语从句[例5] —Who should be responsible for the accident?—The boss, not the workers. They just carried out the order ______. (NMET 2008福建卷)A. as toldB. as are toldC. as tellingD. as they told[解析]A。
as引导方式状语从句，表按照、正如；非限定分句“从属连词+-ed/-ing形式”可以看作是一种省略，即省略了主语和be动词。
究竟使用何种非谓语动词形式取决于主被动关系。
又如：(1) As I explained on the phone, your request will be considered at the next meeting.（NMET 2005浙江卷）(2)Doctors have said that as many as 40 percent of patients don’t take medicine as directed.三、用作关系代词，指代整个句子，as/which/it用法区别[例6] The Beatles, ______ many of you are old enough to remember, came from Liverpool. (NMET 2006天津卷)A. whatB. thatC. howD. as[解析] D。
as作关系代词，在非限制性定语从句中，可指代整个句子内容，置于句首，而which不可；it为代词，用作句子成分，但不用来连接句子，故常和并列连词连用；在限制性定语从句中常与such, the same连用，试比较：(1)I haven’t many toys but I will send you such as I have.我的玩具并不多。
不过，我会把我仅有的一点玩具送给你。
(2)The book is not such that I can advise you to read it.这本书并不怎么样，我没法向你推介。
四、用作从句性替代词，等同于so[例7] —My room gets very cold at night.—______. (NMET 2007江苏卷)A. So is mineB. So mine isC. So does mineD. So mine does[解析]C。
从题干中动词gets得知，助动词应选择do的适当形式，故排除选项A和B；从语序上考虑，排除选项D。
as用作从句性替代词，等同于so，只是用于正式语体中。
如：Our eating habits have changed, as has our way of life.五、as…as结构1．构成倍数比较句型：n times+as…as[例8] What a table! I’ ve never seen such a thing before. It is ______ it is long.（NMET 2005湖北卷）A. half not as wide asB. wide not as half asC. not half as wide asD. as wide as not half[解析]答案C。
not与谓语动词连用构成否定。
as 作从属连词引导比较状语从句，常见结构为as...as，第一个as为副词，后接形容词或副词，第二个as为连词。
程度修饰语应放在第一个as之前。
2.as/so long as[例9] —Have you got any idea for the summer vacation?—I don’t mind where we go ______ there’s sun, sea and beach.( NMET 2008全国卷)A. as ifB. as long asC. now thatD. in order that[解析] B。
as long as最基本词义表示主从句动作延续时间一样长，可引导时间状语从句；若引导条件状语从句，表“只要”，同only if，为唯一条件。
又如：As long as I know the money is safe, I shall not worry about it.（NMET 2003北京卷）3.as far as[例10] ______ I can see, there is only one possible way to keep away from the danger.（NMET 2004北京春季卷）A. As long asB. As far asC. Just asD. Even if[解析] B。
as far as I know\can see\am concerned表据我所知（我看、我所关心的）；as far as 还表“远至”。
4.as much as[例11] The more I think about him, the more reasons I find for loving him ______ I did.（NMET 2005湖南卷）A. as much asB. as long asC. as soon asD. as far as[解析]A。
as much as表程度或数量；as long as表长度或条件；as soon as尽快；as far as 远至，根据。
若用于否定句中，第一个as换为so。
例：Young people in the US don’t care so much about fashion as those in China.5.as well as[例12] John plays football ______, David. (NMET 1994全国卷)A. as wellB. as well asC. so wellD. so well as[解析]B。
if not better than为插入语，对考生答题具有一定干扰。
as well as在功能上相当于并列连词，用来连接两个平行成分，但不能用作并列连词。
注意在连接两个并列谓语动词时，其后的动词使用动词-ing形式；除此之外，所连接的成分前后应保持平行、对等。
