总结
1.as…as结构中，要使用形容词或副词的原形。
2.as…as结构用于肯定句或否定句，so…as只用于否定句，用来表示“不如……那样……”。值得注意的是：它表示的内容总是前者不如后者。使用副词表示“不相等”的句型中，“not as/so…as…”中的not要和助动词do,does,did等一起放在行为动词前，来构成否定句
3.as…as结构中，若出现名词，一般将名词放在as…as中间。若有形容词作定语修饰单数可数名词，其前的不定冠词a/an，须放在形容词之后。
4.as…as结构中如出现表示倍数的词，应放在as…as结构之前。如：
Our school is four times as large as yours.我们的学校比你们的学校要大四倍。
5.as…as结构后接具体数字时，是表示长、短、高、矮、重、轻等的程度，而不是表示两者的比较。如：
Some stones weigh as much as fifteen tons.有些石头重达十五吨。
伴随状语知识大全
定义:
伴随状语是指状语从句的动作伴随主句发生，
它的特点是：它所表达的动作或状态是伴随着句子谓语动词的动作而发生或存在的。
例如：
①He sat in the armchair，reading a newspaper.
他坐在扶手椅里读报。
②All night long he lay awake，thinking of the problem.
他整夜躺在床上睡不着，思考着那个问题。
伴随状语出现的条件
是由一个主语发出两个动作或同一个主语处于两种状态，或同一个主语发出一个动作时又伴随有某一种状态。
伴随状语的逻辑主语一般情况下必须是全句的主语，伴随状语与谓语动词所表示的动作或状态是同时发生的。
伴随状语几种表示方法
一、使用分词形式
The dog entered the room, following his master
(这条狗跟着主人进了屋)。
The master entered the room,followed by his dog
(主人进了屋，后面跟着他的狗)。
二、用with复合结构
The little girls were playing with snow with their hands frozen red
(小女孩们在玩雪，手都冻红了)。
三、用独立主格结构
The little boy goes to school, the little dog accompanying him every day
(这小孩每天去上学，那条小狗陪伴着他)。
四、用形容词

How can you go to the wedding party in rags(你怎能衣衫褴褛地去参加婚宴)？
I went home out of breath(我上气不接下气地回家)。
伴随状语的判断
The dog entered the room, following his master.
一般在分词短语（现在分词表主动过去表被动）前有逗号的是伴随状语。

Much as I like you, I will not marry you. 我虽然很喜欢你，可是不愿与你结婚。 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” “so… 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)。这个分句可以位于句首、句中或句末。 As is well known，oceans cover more than 70％of the earth．
龙文学校1对1英语辅导教师发现近几年高考试卷中有关as一词的题目出现过很多次，其中as或是最佳选项，或是干扰项，或是题干中的关键信息点，涉及到as作为连词、介词、关系代词、副词以及习语等各种用法。所以龙文学习校英语辅导教师结合高考真题将as的用法归纳如下： 一、用作连词的as 1. 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. since B. when C. as D. 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. While B. Since C. As D. 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”）。 3. 引导让步状语从句，通常可与although或though通用，但语序不同，although或though 用于句首，as用于倒装结构。例如：Young as I am, I already know what career I want to follow. /Although（或Though）I am young, I already know what career I want to follow. as 表示让步用于倒装结构，通常将从句的表语、状语或动词前置。如果表语有冠词a/an, 需去掉。例如：Great scholar as he is, he is lacking in common sense./Much as I like you, I couldn’t live with you. 例3 _____ he has limited technical knowledge, the older worker has a lot of experience. A. Since B. Unless C. As D. Although 解析：as 虽然有引导让步状语从句用法，但本题不是倒装结构，故正确答案应是D。 4. 引导方式状语从句，表示“如，像”。例如：When in Rome, do as Romans do./Do to others as you would have others do to you. 例4 We wanted to get home before dark, but it didn’t quite ________ as planned. A. make out B. turn out C. go on D. come up 解析：本题考查动词词组辨析，题干中的“as planned”给同学们提供了重要信息，答案选B。 5. 固定句型：“主句，as +be/do+主语”表示“也一样”。例如：She’s unusually tall, as are both her parents./He’s a doctor, as was his wife before she had children.
比如08年的翻译题：On the other hand, he did not accept （承认、认可、接受）as well founded（使有根据）the charge （指责）made by some of his critics that, while（虽然，尽管）he was a good observe, he had no power of reasoning. 分析：the charge 本应放在动词accept（认为）后，as well founded 作charge的补语：认为指责是有根据的。 但charge 后有过去分词made by...作定语，that 引导的句子作charge的同位语。所以把宾语放在了宾语补语的后面。 （如：take:把某事看作，以为，对待。Take sth as settled:把某事看成已解决，补语用的是过去分词settl ed. 语法说，宾语补足语前可有as 或for。如：take sth for grant ed（承认，同意，准许）:认为某事当然） take sth as of importance =take sth as important:认为某事重要(语法说，of+
名词=该名词的形容词，用of+名词是高级的用法。) 翻译; 另一方面，某些人批评他虽然善于观察，却不具备推理能力，而他认为这种说法也是缺乏根据的。 惯用语as well as用法归纳 一、分清本义与引申义 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not so well as代替not as well as。如： He speaks English as well as her. 他说英语说得跟她一样好。
惯用语as well as用法归纳 一、分清本义与引申义 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not so well as代替 not as well as。如： He speaks English as well as her. 他说英语说得跟她一样好。 She plays every bit as well as the men. 她打得一点不比男人们差。 He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。 He sings as well as, if not better than, Mary. 要是他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 as vegetables. 他既种菜也种花。 She shares (in) my troubles as well as my joys. 她与我同甘共苦。 They have a flat in town as well as a place 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 he has been taking Spanish lessons this summer. 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, 其后的谓语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。
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的用法总结 1．作介词，表示“作为；当作”。如： As a party member, I must be strict with myself． He works in the school as a teacher of math． 2．作连词，引导方式状语从句，意为“像；按照”。如：You must do everything as I asked you to． 3．作连词，引导时间状语从句。意为“当……的时候”。如：She sings as she walks． He came just as I reached the door． 4．作连词，引导原因状语从句。“因为“如： You must hurry up as there is little time left． 5．引导让步状语从句，常用于倒装结构。”尽管“ Hard as he worked, he didn’t pass this examination． Child as he is, he knows a lot． 7．用于一些固定搭配。如： ① as ．．． as．．．与……相同的程度；与……等同 The dress is twice as expensive as that． ② as if ／as though 似乎；好像 He behaved as if nothing had happened． ③ as well as 同（一样也）；和；还 We cannot expect her to do the homework as well as look after the children． ④ such．．．as 像……这样的；such as 例如 I bought a lot of fruits, such as apples, oranges, bananas and so on． ⑦ so as to ．．．以便, 为了 She saved the money so as to support the family． ⑧ as a matter of fact 其实；实际上 As a matter of fact, I’m very fond of housework． ⑨ as a result 结果 (发生某种情况) As a result， he had been given an excellent job． ⑩ as long as 只要 As long as you work hard, you will succeed sooner or later．
