A.than

B. like

C.as

D.so

翻译：海里的好鱼是取之不尽的。

答案：C.解析：这是一句英语谚语，指虽然失去一个机会，还会有很多机会。原句不是比较级句型，不能用than；like 作为介词或动词，后不能跟动词；so作为副词，后面也不能跟动词，so 作为连词连接的是整个句子；as 常用作关联词后置于so或as表示同等的程度或量。

答案：B. 解析：让步状语从句多由although和though引导，但是也可以把让步的成分（形容词、副词、动词）提前，此时用连词as或though. 例如：Poor as/though he was, he was honest；Try as you will, you won’t manage it.；

Much as I admire him as a writer, I do not like him as a man.从语法的角度来看，使用倒装形式的让步结构时，既可以用as, 也可以用though, 但是把though 用于倒装结构多属于口语。

A.who

B.as

C.like

D.that

翻译：即便杰瑞笨，他也不可能做出这种事来。

A.I got a job as soon as I left university.

B.As there was no answer, I wrote again.

C.You must do the exercises as I show you.

D.Wealthy as he is, Mark is not a happy man.

答案：B. 解析：选项A中as soon as I left university是时间状语从句。选项B中as 为连词，相当于because,引导原因状语从句。选项C中as“像.......一样”是连词，引导方式状语从句。选项D中，as为“尽管”引导让步状语从句，且该句使用倒装结构。

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)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。

(4)as far as

(5)as well as

几个关于as的常见短语：

1.so/as far as表“据…, 就… ”

2.so as to do=in order to do表“为了”但so as to do只能放句中

3.so.....as to do表"如此..以至于“相当于so that引导的“结果状语从句

4.Not only…but…as well=not only…but also表“不但..而且..”

As well as=not only…but also

Not only you but also your wife is friendly to me.(动词跟后面的wife）

Your wife as well as you is friendly to me.（动词跟前

面的wife)

不但你而且你妻子也对我很好。

注意：you look as well as you were./you look as well as before.

5.As well表“又，也”常用于句尾（无需逗号分开）

The skirt is small for me as well.这条裙子对于我来说也小了。

6.May as well=might as well表“还不如，也好”相当于=had better

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 as的用法

其基本意思为“与…一样”，其中的第一个as为副词，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。如： (1) 在否定句中，第一个as 也可换成so。如： 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+复数名词+as”。如： 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. 我不像原来想像的有那么多钱。 其间接形容词时，有时该形容词还可修饰另一名词，但这个名词应带有不定冠词(注意词序)。如： She is as good a teacher as her mother. 她和她妈妈一样是位好老师。 也可说。如：She is a teacher as good as her mother. 但不说。如：She is as a good teacher as her mother. / They are as good teachers as us. (3) 第二个as后接从句时，该as通常为连词，但有时这个as还充当其后从句的主语或宾语，此时该as实为关系代词。如： I gave him as much as he could eat. 他能吃多少，我就给了他多少。 We’ve got food for as many people as want it. 我们的食物，无论多少人吃都够了。 (4) 该结构根据情况可用使用以下修饰语。如：(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等，并且这些修饰语必须置于第一个as之前，而不能置于其后。如： He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。 This dress is twice as expensive as that. 这件连衣裙比那件贵一倍。 (5) 若第二个as引导一个表示将来意义的从句，则该从句可用现在时表示将来，也可直接使用将来时态。如： We’ll get there as soon as you do [will]. 你一到，我们就到。

英语中as用法详解

as 用法详解 1.用作连词，表示让步(意为：虽然，尽管)，要用于倒装句，且倒装后位于句首的名词通常不用冠词(等于though, 但语气稍弱)。如： Child as[though]he was, he did quite well. 他虽是个孩子，但已干得很不错。 2.用作关系代词，主要用法有二。如： (1)用在such, same, as等之后，引导限制性定语从句。如： This is the same watch as I lost. 这块表跟我丢失的那块一样。 Such men as (=Those men who) heard of him praised him. 听说过他的人都赞扬他。 (2)单独用作关系代词，引导非限制性定语从句，可放在主句之前(常译为：正如)或之后(常译为：这一点)，且主从句之间一般要用逗号隔开。如： He was absent, as is often the case. 他缺席了，这是常有的事。 As was expected, he succeeded at last. 正如我们所料，他终于成功了。 3.用来表示目的，下面两种句子结构都可以。如： 仔细写以便把每句话都写清楚。 正：Write carefully so as to make every sentence clear. 正：Write so carefully as to make every sentence clear. 4.在正式文体(尤其是文学体裁)中，as后可用倒装语序表示“…也一样”这类意思(现代英语通常so表示这一用法)。如： He travelled agreat deal, as did most of his friends. 他去过许多地方旅游，他的多数朋友也是一样。 He plays the piano, as does his mother. 他会弹钢琴，他母亲也会。 注：用作连词，表示原因(参见because)，表示时间(参见when)。 5.用于as if as though, 意为“仿佛”、“似乎”。两者一般可通用(但注意不能说as although)。用法上注意几点： (1)as if [though] 可引导状语从句和表语从句，从句谓语根据语义的要求，可用陈述语气(若可能为事实)或虚拟语气(若为假设或不太可能是事实)。如： It looks as if it is going to rain. 天似乎要下雨了。 It seems as if you’re right. 似乎你是对的。 He talks asthough he knew everything. 他夸夸其谈，好像无所不知。 When apencil is partly in a glass of water, it looks as if it werebroken. 当把一支铅笔的一部分放在一杯水里时，它看起来好像折断了似的。 当主句谓语是过去时态时，从句谓语常可用陈述语气。如： He pausedas though he found a difficulty. 他停了下来，似乎遇到了一个难题。 She felt as if she lost something. 他觉得似乎丢了什么东西。 (2)当从句主语与主句主语一致，且从句谓语中又包括有动词be时，从句主语及其谓语中的动词be通常可以省去。如：

As的用法归纳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'thave 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: We 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 dan ces as she si ngs 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。 As he grew older, he became more intelligent. 随着他年龄的增长，他变得更 有才智了。 ③表示两个短促行为或事件几乎同时发生。例如: I thought of it just as you opened your mouth. 恰好在你开口时，我想到了它。 Just as the flying worm hit her face, she gave a loud cry. 恰巧在飞虫撞到她脸上时，她大哭起来。 2. 引导原因状语从句 as，because, si nee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： I do it because I like it. 我做这件事是因为我喜欢。 Since many of the customers work during the day, Billy has to collect the money at night. 因为许多顾客白天上班,所以毕利只好晚上去收钱。 As she has been ill perhaps she'll need some help. 她由于生病可能需要些帮

英语语法中as的三大用法

英语语法中as的三大用法 第一个单词prospect，它表示的意思是“前景”，常用复数形式prospects。第二个单词wage, 是工资的意思，通常指的是按短期（小时，星期）计算的工资，要注意和salary 进行区分，salary指按长期（月，年）计算的工资。最后一个单词transform，这个词很好记，单词中“trans” 这个前缀就是“转变、变换”的意思，所以transform的意思就是转变、改变。

首先句子的主语非常好判断，那就是“parents and students”，后面跟的是who 引导的定语从句，从句中谓语动词是invested。后面的worry就是整个主句的谓语动词了。句子中的as, 连接的是前后两句话，但因为as的含义非常多，在此具体是什么意思，我们还要等到看完整个句子才能做出判断。 As后面的从句中，“technological advances and changes”, 是从句的主语，谓语动词为transform。通过分析句子含义，我们可以发现，as前面其实是事情发生的结果（父母和学生担心毕业前景），而as后面是事情发生的原因（国内和全球市场变化，薪资降低），所以as在这里的含义我们可以理解为“由于”。 经过拆分，现在句子已经非常清晰了。刚才我们讲到了as 的含义有很多，所以今天，艾伦英语部落就为你进行as这个词常用用法的拓展，一共有三种。

这里的as就是作为副词出现，同时句子中也用到了经常和as搭配使用的短语“as…as”, 表示“和…一样”。 我们看到第一个句子中，“作为一个中文老师”，as用作介词出现在这里，表达的意思是“作为”，第二个句子里， as 的意思为“如同，好像”，句子中提到的“像小男孩一样”。同样是介词，但在两个句子中表达的意思完全不同，大家要注意区分。 ③ 用作连接词，可以表示“当…时”，“因为”，“随着”等。 As作连接词使用时，含义比较多，我们分别来看几个例句：

as...as的用法

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...

高考英语易错词汇解析asif用法举例辨析

as if用法举例辨析 It seems that / as if ...用法举例辨析 此句型实质上是“主+系+表”结构。其中it是人称代词，并无实意，指的是某种情况，seems为系动词，that / as if 引导表语从句。 一、It seems that …表示“看起来……”。 强调根据一定的事实所得出的一种接近于实际情况的判断，可以说表示事实。(可以转换成“名词或代词 + seem +动词不定式”句型，其意不变，如果动词不定式为to be + 形容词时，to be往往省略。) It seems that it is more difficult for women to get to the top of the company. 妇女似乎更难提升到公司的最高职位。 It seems that no one knows what has happened in the park. (No one seems to know what has happened in the park.) 似乎没有人知道在公园里发生了什么事。 It seems to me that he has known everything. (He seems to have known everything) 在我看来他似乎什么事都知道了。 It seems to me that Mr. White will not come again. 依我看，怀特先生不会再来了。 It seems that she is happy. 她似乎很高兴。 It seems that he likes his new job. 他看起来很喜欢他的新工作。 It seems that they don't like the idea. 他们似乎不喜欢这个主意。 It seems that he is lying.看来他在撒谎。 二、It seems as if ...也表示“看起来……，似乎……”。 使用该句型表示可能：若从句表示的是很可能实现的事情，从句谓语用陈述语气;若从句表示的是与事实相反的假设或实现的可能性很小的事情时，则从句谓语要用虚拟语气。 1、从句的谓语动词常用虚拟语气来表示所设想的事情不真实或不可能发生/存在。 It seems as if she had read this novel.看来她好像看过这本小说。 It seems as if it were autumn. 现在仿佛是秋天似的。 It seems as if it were spring already. 似乎春天已经来了。 It seems as if he knew everything. 好像他什么都知道似的。 It seems as if she had been to England. 好像她到过英国似的。 It seems as if they had never seen each other before. 仿佛他们以前从未见过面。It seems as if he were in a dream.看来他像是在做梦。 It seemed as if the good man were trying to teach us all he knew at this last lesson.这个好心人仿佛要在最后这一堂课上把他的全部知识教给我们。 2、如果可能性很大则用陈述语气，或者句中的情况可能发生或可能被设想为真实，则仍然用陈述语气。 It seems as if our team is going to win.看来我们队要胜了。 It seems as if he has learned by heart a speech written by someone else.看来他像是背了一篇由别人写的演讲稿。 It seems as if he has been at the scene of the crime似乎他好像在犯罪现场。 It seems as if it is going to rain. (It seems to rain) 看来天要下雨了。

英语语法之as的用法

as的用法 as这个词看似简单，但用法却是很多的，对它的正确理解关系到英语应用能力的提高，因此我们有必要对其用法和搭配进行详细阐述。 一、as作介词 1. 区别as和like as作为介词时，可以表示“像……”，这时它可以和like互用；as还可以表示“以……身份”或“作为……”，“当作……”，但like不能。 e.g. I) They lived and fought among the people as “fish in water”. (as相当于like) II) As a scientist, he was dedicated to (致力于) the truth. (这里不可以用like) II) They talked as old friends. (他们确乎是老朋友。) They talked like old friends. (他们像老朋友一样。) 2. as引导的介词短语在句中可以充当： a) 宾语补足语 e.g. I) She spoke of me as her dearest friend. II) The plan struck me as very much worthwhile. III) Y ou mustn’t think of me as (being) unhappy. b) 主语补足语 e.g. I) She is well-known as being very cheerful. II) He is sometimes portrayed as belonging to another century. III) That picture is looked upon as very valuable. 常用于这类结构的动词有：accept, consider, describe, elect, interpret (理解), look upon, perceive, recognize, refer to, regard, see, strike, take, think of, treat, view等等。 二、as作连词 1. 作“当……的时候”,引导时间状语从句。注意与when、while的用法区别。 A. when作"当……的时候"解,可以指较短的(一点)时间,也可指一段时间。 e.g. I)When he was at college, he could speak several foreign languages. II) When the clock struck twelve, all the lights in the street went out. B. 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。 e.g. Work while you work. Play while you play. C. 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……”。 e.g.I)The girl dances as she sings on the stage. II) He looked behind from time to time as he went forward. 2)表示两个同步发展的动作或行为,译为“随着……”。 e.g. I) As time went on / by, she became more and more worried. II) As children get older, they become more and more interested in the things around them. 3)表示两个短促行为或事件几乎同时发生。 e.g. I) I thought of it just as you opened your mouth.

第一个as是副词，第二个as是连词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。

as well as的用法

1．用于本义 as well as用于本义，可视为as…as结构与well的自然搭配，其意为“与……一样好”，在否定句中可用notso well as代替not as well as。如： He speaks English as well asshe．他说英语说得跟她一样好。 She plays every bit as well asthe men．她打得一点不比男人们差。 He doesn’t play half so well ashis sister．他演奏的水平不及他姐姐的一半。 He sings as well as．if not bet-ter than，Mary．他要是唱歌不比玛丽唱得更好，但至少也是一样好。 2．用于引申义 用于引申义，表示“不但……而且”“既是……也是”“而且”“还”。如： He grows flowers aS well asvegetables．他既种菜也种花。 She shares(in)my troubles aswell as my joys．她与我同甘共苦。 They have a flat in town as wellas in the Country．他们在城里有一套公寓，在乡村还有一所房子。 注：有时还可译为“除……之外，还”，与besides，in addition to的用法相似。如：As well aS learning to swim hehas been taking Spanish lessons thissummer．今年夏天，他除了学习游泳外，他还在上西班牙语课。 二、弄清强调重点 A as well as B这一结构强调的重点是A不是B，即A as well as B=not only B but also A,注意体会以下例句的译文： She is clever as well as beautiful．她不但漂亮，而且聪明。 He speaks Spanish as well as English and French．他不仅会说英语和法语，而且会说西班牙语。 Actors have to learn their cues as well as their own lines．演员不仅要记住台词，还要记住其他演员的暗示。 三、把握主谓一致 当as well as连接两个成分作主语时，其后谓语的单复数形式通常要与前面一个主语保持一致。如： Tom as well as his parents is going to London．汤姆和他的父母要去伦敦。 The captain，as well as the other players，was tired．队长和其他队员都累了。 但是，有时即使as well as前面一个成分为单数，其后的谓语也可能用复数，尤其是当as well as后面一个成分比较长且该结构没有用逗号隔开时。如： His appearance as well as his strange way of talking make me suspicious．他的外表以及他那奇怪的谈吐引起我的怀疑。 四、牢记后续动词的形式 as well as后接动词到底该用什么形式，这是一比较复杂的问题，归纳起来有以下几点值得注意：
