例析历年高考试题归结as难点用法

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。

其基本结构为:as+adj./adv.+as,否定式为not as/so+adj./adv.+as。

而几个as...as的特殊用法却是考查重点。

(一)as/so long as只要……(引导条件状语从句),如:(10江西)22、— Our holiday cost a lot of money.—Did it?Well,that doesn’t matter________you enjoyed yourselves.A.as long asB.unlessC.as soon asD.though答案:A解析:as long as“只要”;后一句为:只要你玩的开心,花多少钱就不重要。

(二)as well as的使用频率很高,用途非常广泛。

但最常考的是用作连词和介词,连接两个相同的成分,如名词、形容词、介词,意为“不但……而且……”、“既……又……”。

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。

as 的用法：as 作介，用法和一，其含“作”。

但是as 作性，其用法和功能多，可以引各从句，as 引原因状从句、状
从句、方式状从句、步状从句和定从句。

as 的用法
1、 as 做介，意思是“作”
例句：
French is known as the most beautiful language in the world.
法以世界上最美的言著称。

2、 as 做，引状从句，意思是“当⋯⋯的候”
例句：
My mother was cooking fish as I arrived home.
当我到家的候，我正在做。

3、 as 做，引原因状从句，意思是“因”
例句：
As rain has fallen, the air is cooler.
因下雨，所以空气比凉爽。

4、 as 做，引步状从句，意思是“ 然”
例句：
Young as he is, he has been one of the most famous painters in our country.
然他很年，但已成我国家最有名的画家之一。

5、 as 做，引方式状从句，意思是“以⋯⋯方式”
例句：

入乡随俗
6、 as 做关系代词，引导定语从句
例句：
This is the same game as I played yesterday. 这和我昨天玩的游戏一样。

AS用法总结一、用作连词的as1. 引导时间状语从句，表示“当……的时候”，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. sinceB. whenC. asD. 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. WhileB. SinceC. AsD. 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”）。

as虽小，功能强大as是英语中意义广泛、用法灵活且复现率极高的词, 每年高考命题和其他各级命题都会从不同角度对其进行考查.它在词性上有介词、连词和代词等，主要有以下用法。

一、作介词表示“作为，当作；以……身份"，其后常接名词。

例如：Johnson works as a doctor. 约翰逊（的职业）是个医生。

I like him as a person，but I don’t think much of him as s writer. 作为一个普通人，我是喜欢他的，但是作为一名作家，我对他的评价并不高。

Wang Baoqiang’s talents as a film actor were soon recognized. 作为电影演员，王宝强的天才很快得到了赏识。

【注意】as和like都可以作介词,但意义不同。

as表示“以实际的身份或地位"，like则表示“与……相似，以与……相类似的方式”。

例如：He has been playing tennis as a professional for five years. （= he is a professional) 他作为一名职业选手已经打了五年网球了。

He plays tennis like a professional. （= he is not a professional but he plays as well as a professional）他打网球就像职业选手一样。

二、作连词as作连词时，用法比较多，可以引导时间状语从句、原因状语从句、方式状语从句、让步状语从句等。

（一）as引导时间状语从句表示主句和从句的动作同时发生，并具有延续的含义,意思是“正当……的时候；随着……"。

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。

as倒装句的用法高考一、引言倒装句是英语中常用的一种句式，尤其在高考英语中经常出现。

正确使用倒装句能够增加文章的多样性和丰富性，提高文采和语言表达的水平。

本文将对AS倒装句的用法进行介绍，并举例说明其在高考中的应用。

二、AS倒装句的定义与基本结构AS倒装句即以"As"引导的部分倒装句。

聚焦高考题，透视as考点as的用法既是高考重点掌握的内容，又是重现率较高的知识点，结合高考试题，对它以用法作一简要归纳。

1．as做关系代词，引导非限制性定语从句as引导非限制性定语从句时，指代逗号前的整个句子（即先行词），常翻译为“正如，正像”，可置于句首或句末。

（注：which只能放在句中）。

例: _____is reported in the newspaper, talks between the two countries are making progress.(2004北京卷)A.ItB.AsC. ThatD. What答案B。

as it reported意思是“正如所报道的”。

As引导非限制性定语从句放在句首。

What 只能引导名词性从句。

That 只能引导非限制性定语从句。

2．as做关系代词，引导限制性定语从句在这个用法中，关系代词常出现在the same as,such as, so…as, as…as, 等结构中。

例: His plan was such a good one _____ we all agreed to accept it.(2006陕西卷)A. asB.thatC. soD.and答案B。

即使句中有such,但从句中accept后面有宾语,所以这是such…that引导的结果状语从句。

3．as 引导状语从句表示“即使”。

句子必须用倒装结构。

As引导让步状语从句，从句中的表语、状语或主要动词应移到句首。

直击高考试题，透视“ａｓ”考点作者：美娟来源：《新校园·学习版》2008年第01期“as”虽小，但在英语中的使用却是非常广泛的，且它的用法亦是高考考查的重点内容。

笔者将结合近几年高考试题，对它的用法作简要剖析归纳，望对同学们有所启发和帮助。

【考点一】as作为关系代词，引导定语从句关系代词as既可以引导限制性定语从句，也可以引导非限制性定语从句，as在从句中作主语、宾语和表语。

其具体用法如下：1.引导限制性定语从句as在引导限制性定语从句时，常用于以下句式：(1)such+名词+as… 意为“像…一样的”,“像…之类”(2) the same + 名词+as… 意为“和…同样的”例如:They are facing the same problem as we did the year before last year.他们正面对前年我们所碰到的相同问题。

I have never heard such terrible stories as he tells.我从未听到过如他讲的那么可怕的故事。

[例] He is such a lazy man _____ nobody wants to work with ____.(2006年成都卷)A. as; himB. that; /C. as; /D. whom; him［解析］答案为C,先行词用such来修饰时，关系代词只用as; as又在定语从句中作work with的宾语，故第二个空不能再用him。

There at the door stood a girl about the same height_____. （2004年北京春季卷）A. as meB. as mineC. with mineD. with me［解析］the same …as是“和…一样”，根据句意，比较的对象是人的高度，故答案为B。

2.引导非限制性定语从句as 在引导非限制性定语从句时，其关系代词为整个句子，as在从句中作主语、宾语和表语，可意为“正如…”“这一点”“那一情况，像….一样”。

as用法总结-最新文档as用法总结一、as用作介词，后接名词，此时as意义为“作为……”，它用来指所提到的人或物的性质，用途，身份请注意：as后面所接的名词的单复数应该与它所指的人或物的单复数一致。

如：As a student，he is hardworking.As students，they are hardworking.高考真题例句：（2005湖南） We went to Canada to travel and my cousin acted as our guide.二、as用作副词，用于比较结构“as +形容词或副词的原级+ as”中，表示两者或两方面的比较，也可以显示所提到的人或物的程度（北师大版高中英语必修一第12页）It can get as cold as minus 40 or 50 degrees at night.（北师大版高中英语必修三第12页） It is not as big as a fly in your house！as用于比较结构，而比较结构有多种变化形式。

如：My house is 3 times as large as yours.=My house is 3 times larger than yours.=My house is 3 times the size of yours.在以上的结构变化形式中，要注意倍数词必须置于“as +形容词或副词的原级+ as”之前。

高考真题再现（斜体字选项为正确答案，下同）：（2005湖北） What a table！I’ve never seen such a thing before. It is it is long.A. half not as wide asB. wide not as half asC. not half as wide asD. as wide as not half分析：此题中的“as...as结构”并不是用于两者间的比较，而是显示所提到的人（即John）的程度，说明其具体有多高。
