关于"as" 的用法小结

我在浏览其他网站时发现了有关AS用法的总结，自己觉得非常比较适合我自己，现将他贴出来共享。非常感谢总结用法的老师们！！！

As的用法小结

as可以作连词、介词及关系代词和副词。现将其用法小结如下:

（一）、as作连词的用法:

1.作“在-------期间，当----的时候”引导时间状语从句.注意与when、while的用法区别。

①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. 如:

The girl sings as she goes to school.

He looked behind occasionally as he went forward in the forest.

2)表示两个同步发生的动作或行为,意思是随着-----的发展.如:

As time went on / by, she became more and more beautiful .

As children get older, they become more and more interested in everything.

3)表示两个短暂行为或事情几乎同时发生.如:I watched her as she read the book.

I thought of it just as you opened your mouth.

Just as the flying worm hit her face, she gave a loud cry.

4)接在名词后面表示某一个年龄段时.如:

As a young man, he was active in sports.

②when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 I was at college, I could speak several foreign languages. When the clock struck twelve, I had slept for 2hours.

③while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.

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 he’s been ill for ages, I will help him.

As / Since you’re not feeling well, you may stay at home.

As he wasn’t ready , 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:

Do as I told you.

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 as much as possible.

I don’t speak English so/ as well as she does.

5. 表示虽然,尽管等,引导让步状语从句,常用倒装语序,模式为:

adj. /adv. / n.+as +主语+谓语+主句。如: Young as he is, he knows much.

Tired as they were, they walked on.

6. 表示也------一样。She is a doctor, as was her husband.

（二）、as作关系代词,引导定语从句,表示正如,这一点.如:

He is very careful, as we all know.

As is well-known, Taiwan belongs to China.

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 girl as she can learn anything quickly.

I was reading the same book as he bought yesterday.

（三）、as作介词的用法.

1.表示好像。如:He dressed as a policeman.

2. 表示作为当作。如：I found a job as a guide.

3. 当某人是某身份时。如：As a child , she was sent to abroad.

4. 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 Party member, I’ll take the lead in everything. (状语)

She works as a model. (状语)

She has me as one of her best friends.(引起宾语补足语)

（四）、作副词的用法 1 表示与------等同。如：This dress is twice as expensive as that one. 2 像，如等。如：As before, he remained unmoved.

总之，通过以上的分析，我们对as的词性和用法有了比较全面的理解和把握，才能在实际的运用中做到心中有数，应付裕如。

AS用法（六级考试总结）

在英语学习中，“as”作为一个词性多，词义广，出现频率高的词，是六级考生必须熟练掌握，并且应该能够正确加以运用的重点词汇。这里，结合例句，着重列举一些常用的，以及在考试中经常出现的短语及用法。

1．as do I ／as I do

a）He writes as his father did．他像他爸爸一样写作。

注：表示比较或方式的as从句一般使用正常语序。但是，在正式语体中，也可以采用倒装，但不是强制性的，而是选择性的。例如：

b）She looks forward ，as does her secretary ,to the completion of the building．她像她的秘书一样盼望工程竣工。

c）When in Rome do as Romans do．入乡随俗。

2．．．．as he is

a）Talented as he is，he is not yet ready to turn professional．别看他有天份，他还没把心用到专业上去。

注：这是一种表示让步的分句，主要用于正式文体。Talented as he is ＝Though he is talented，as引出的主谓语倒装是强制性的，因为若将as置于句首，就不是让步状语从句了。由though 引出的让步状语从句，也可以使用这种语序，但不是强制性的。例如：

b）Coward though he is ，do not bully him．尽管他是个胆小鬼，但不要欺负他。

3．as far as ／so far as

a）So far as I know，he will be away for three months．据我所知，他将离开这里三个月。注：当as far as和so far as作“在……范围内……、一直到、到……那么远”解时，它们是可以互换的。当表示形容词、副词同级比较时，要求在肯定句中使用as far as。例如：

b）We didn\'t go so／as far as the bridge．我们没有走到桥那么远。

4．as／so far as to do（doing）something意思是：“竟到了……程度”。

a）At last，she went so far as to bring him to the apartment．最后，她竟把他带到了公寓。注：as／so far as之后既可跟不定式也可跟动名词。例如：

b）I have considered having a car，but I haven\'t got so far as buying it yet．我是考虑要买一辆汽车，但是还没有到决定买的程度。

5．as follows意思是“如下的”。

a）His arguments are as follows．他的论点如下。

注：as follows是固定成语，不管引出的事物是单数还是复数，都只能用as follows（＝as it follows），而不能用as follow。例如：

b）He explained it as follows ．（＝His explanation was as follows ．）他的说明如下。

6．as for／as to意思是“至于、关于”。

a）Much pasture land is under water；and as for the grain，most of which has been ruined．大

部分牧场都进了水，至于谷物，大部分都被冲毁了。

注：as for在语体上不如as to正式；前者着重话题的转换，因此，它不能用于文章的开头。例如：

b）As to the question you raised in your last letter ，I think．．．．关于你上封信提出的问题，我认为……。

7．as good as意思是“差不多，几乎”。此外，该结构还保留其原意“和……一样好”。

a）Don\'t worry，the matter \'s as good as settled．别担心，问题差不多已经解决了。

b）When the car was repaired，it looked as good as new．当这辆车修好的时候，它看起来差不多像新的一样。

8．as and when“到时候”，指将来的某一未定的事或时候。

We\'ll decide on our team as and when we qualify for the competition．我们等到有资格参加比赛时，再来决定本队的参赛人员。

9．as if you were／are

a）He walks as if he were drunk．他走路的样子好像是喝醉了似的。（说话人认为他并没有喝醉）

b）He walks as if he is drunk．他走路好像喝醉了。

注：一般来讲，如果as if表达的内容与事实相反或者是一种假使，通常使用虚拟语气。如例句a）。如果as if所表达的内容被看作是事实，就要使用陈述语气。如例句b）。

10．as it were ／was（is）

a）As it was，they had no unity，no sense of cooperation ．事实上，他们不团结，没有合作意识。

注：as it is ／was是个成语，意思是：“事实上、实际上”。而as it were在意义和用法上与as it is ／was完全不同，意思是：“可以说是、似乎是、仿佛”，它所表达的内容不太肯定。例如：

b）He is ，as it were，a walking dictionary．他简直可以说是一部活字典。

c）He is my best friend，my brother as it were．他是我最好的朋友，可以说是我的兄弟。11．as long ago as／as long as

a）As long ago as the eleventh century the Chinese people not only invented the com pass but also used it in navigation．早在十一世纪中国人就不仅发明了指南针，而且还把它用到航海上。b）I\'m happy as long as you are happy．只要你幸福，我就感到幸福。

c）As long as you act so m ean，you can\'t expect anybody to do anything for you．由于你行为卑劣，你不要指望有人会帮助你。

注：as long ago as可译为“早在……”。见例句a）。as long as／so long as引导一个条件状语从句，通常译为“只要”。见例句b）。此外，它还可以引导原因状语从句。见例句c）。12．as long as ／so long as

a）You can go out ，as long as you promise to be back before 10o\'clock．只要你答应10点钟以前回来，你就可以出去。

注：当as long as和so long as作“只要”解时，可以看作是同义的，但是，当用于同级比较时，只能用as long as，而不能用so long as。见例句b）。

b）You can stay here as long as you want．你希望在这里呆多久就呆多久。

eg:

As he was not ready in time,we went without him.

(4)按照，正如（表示方式）

eg：

Do as the teacher says.

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 用法区别用作介词，[例1] Let’learn to use the problem we are facing ______ a stepping-stone s to future success.( NMET 2008 全国卷) A. to B. for C. as D. 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 用法区别表时间，[例2] Mother was worried because little Alice was ill, especially ______ Father was away in France. (NMET 1994 全国卷) A. as B. that C. during D. 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 tim e，while 表而“两相对照”。2．表原因，as/because/since/for 用法区别表原因，[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. as B. if C. when D. 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[来源:学科网ZXXK] 表转折，引导让步状语从句[来源: [例4] ______, he talks a lot about his favorite singers after class. (NMET 2005 重庆卷）A. A quiet student as he may be C. Be a quiet student as he may B. Quiet student as he may be D. 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 told B. as are told C. as telling D. as they told [解析]A。引导方式状语从句，as 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, y our 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 directed. 三、用作关系代词，指代整个句子，as/which/it 用法区别用作关系代词，指代整个句子，[例6] The Beatles, ______ many of you are old enough to remember, came from Liverpool. (NMET 2006 天津卷) A. what B. that C. how D. 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：[来源:https://www.360docs.net/doc/2a8855862.html,] (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 用作从句性替代词，[例7] —My room gets very cold at night. —______. (NMET 2007 江苏卷) A. So is mine does B. So mine is C. So does mine D. So mine [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as…1．构成倍数比较句型：n times+as…as 构成倍数比较句型：times+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 as C. not half as wide as B. wide not as half as D. 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?[来源:学&科&网] —I don’t mind where we go ______ there’s sun, sea and beach.( NMET 2008 全国卷) A. as if B. as long as C. now that D. 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 as B. As far as C. Just as D. 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 as B. as long as C. as soon as D. 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；far as 远至，as 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 a s [例12] John plays football ______, David.

(NMET 1994 全国卷) A. as well so well as B. as well as C. so well D. [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。试比较：?Computers have been put into robots and _____to make mobile phones as well as _______with medical operations. (原创模拟) A. used ; to help using; helped B. used; help C. using; helping D. ?Computers have been put into robots as well as _____to make mobile phones and _______with medical operations. (原创模拟)[来源:https://www.360docs.net/doc/2a8855862.html,] A. used; to help using; h elped B. having been used; help C. being used; helping D. 答案与解析：?B ?B ?中and 为并列连词，used 与谓语动词put 保持一致。答案与解析：B；B。as well as 用来连接两个并列状语，作不定式的宾语，故make 与help 保持一致；?中as well as 用来连接两个并列动词，故紧随其后的动词使用-ing 形式，并与谓语动词照应，使用having been used 形式。其后and 为并列连词，连接并列状语，作不定式的宾语，保持一致。6.as good as [例13] He said he would do whatever he could to help me, and he was ______ his word. A. as good as B. as well as C. as much as D. as many as [解析]A。as good as 最基本词义是“和……一样好”；还可表示“几乎，简直是”，其后接名词、动词或形容词均可，在功能上相当于副词very nearly。如：?The work is as good as finished.工作基本完成。?If he finds out, I’m as good as dead.要是他发现了，我就完了。六、as 其他常见搭配1．so as to [例14] All these gifts must be mailed immediately ______ in time for Christmas.（NMET 2005 辽宁卷）A. in order to have received C. so as to be received B. in order to receive D. so as to be receiving [解析] C。so+(adj./adv.)as to do 既表目的又可表结果，在表目的时可以和in order to 换用但不可置于句首。so 后接形容词或副词时只表结果。此题结合时态和语态对考生进行综合考查。试比较：[例15] My English teacher’s humor was ______ make every student burst into laughter.( NMET 2008 江西卷) A. so as to B. suc h as to C. such that D. so that [解析]B。从题干动词make 可以看出，选项C 和D 应排除，so\such that 为从属连词，后接从句；此处such 为代词，表这样的人或物，作表语，后续不定式表结果，其前加as to 以示强调。试比较：My English teacher’s humor was such that makes every student burst into laughter.[来源:学科网ZXXK][来源:Z_xx_https://www.360docs.net/doc/2a8855862.html,] 2．as against/for/to/with [例16] ______ pandas, golden monkeys are in danger of dying out in our country.

As with [解析] D。此题考查as 的常见搭配。as against 与……相对；as for somebody\something 就……而言；to(依照一定的标准或原则)根据、as 依照；with as 和……一样。3. as if/though [例17] Elize remembers everything exactly as if it ______ yesterday.( NMET 2006 全国卷) A. was happening B. happens C. has happened D. happened [解析]D。as if 引导方式状语从句，同时涉及虚拟语气的用法。主从句动作同时发生，对现在假设，从句用一般过去时；若对过去假设则用过去完成时。as if 后还可接to do\doing 等。如：He opens his mouth as if to speak.他张开嘴好像要说话。4.as 还有以下常见搭配：还有以下常见搭配：(1) Leave the book as it was 把书原样放好。was.
