As引导的各种从句归纳
As引导的从句之迟辟智美创作一、As引导让步状语从句为了帮手同学们全面掌握让步状语从句的倒装用法，本文将这类语法现象归纳为以下五种句型：1、名词+ as / though +主语 +动词King as he was，he was unhappy. 他虽是国王，但他其实不幸福.Child as he is，he knows to help other. 他虽是个孩子，却知道帮手他人.【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语.另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词.比力：Boy as ［though］ he is， he likes to play with girls.=Though he is a boy，he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩.Strong man as ［though］ he is，General Botha has been severely put to the test during the past few weeks.= Though heis a strong man， General Botha has been severely put to the test during the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验.2、形容词+ as / though + 主语 + 动词Successful as he is，he is not proud. 他虽然胜利，但不骄傲.Improbable as it seems，it’s true. 虽然看起来不太可能，但却是真的.Stupid as it sounds，I was so in love with her that I believed her. 尽管听起来很愚蠢，我是如此爱她竟然相信了她的话. Patient as he was，he didn’t like waiting that long. 他虽说有耐心，也不愿等这么长.Beautiful though the necklace was，we thought it was over-priced. 那条项链虽然很漂亮，我们认为价钱太高.【说明】其中的动词也通常为连系动词，也就是说位于句首的形容词是其后连系动词的表语.3、副词+ as / though + 主语 + 动词Much as I like Paris，I couldn’t live there. 尽管我喜欢巴黎，但我不能住在那里.Hard though they tried，they couldn’t make her change her mind. 尽管他们做了很年夜努力，却没法让她改变主意.Fast as you read，you can’t finish the book in two days. 尽管你读得很快，你总不能在两天之内就读完这本书.He was unable to make much progress，hard as he tried. 尽管他做了努力，却未能取得很年夜进步.【说明】有的辞书将 much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词.再如：Much as I admire him as a writer，I do not like him as a man. 他作为一名作家我很佩服他，但我却不喜欢他这个人.Much as I like you，I couldn’t live with you. 我尽管很喜欢你，却不能和你在一起生活.4、动词原形+ as / though + 主语 + 动词Object as you may，I’ll go.纵使你反对，我也要去.Try as he might，he couldn’t solve the problem. 尽管他想方设法，却未解决这个问题.Search as they would，they would find nobody in the house. 无论怎样搜查，他们在房子里仍然没有找到一个人.Dislike him as we may，we must acknowledge his greatness. 尽管我们不喜欢他，但必需供认他的伟年夜.Lose money as I did，we got a lot of experience. 钱虽然丢了，我们却获得了许多经验.Fail in the election as he did，he became famous for his fiery speech against slavery. 尽管落选了，但他却以其反对奴隶制的激烈演说而出了名.【说明】主语后的动词通常为 may，might，would，did 等情态动词或助动词(若暗示情态意义，则选用情态动词；若陈说事实，则用 did，do 等助动词).5、分词+ as / though + 主语 + 动词Raining hard as it is，I’m going out for a walk. 虽然正在下着年夜雨，我还是要出去散步.Surrounded as we were by the enemy，we managed to march forward. 虽然我们被仇敌包围着，但我们还是设法前进了.Munching the apple as he was，he had got an eye for all John’s movements. 他尽管在一个劲地嚼着苹果，但仍警惕着约翰的一举一动.6、弥补说明1）这类倒装的让步状语从句可用as， though来引导，不能用 although 来引导；可是，未倒装的让步状语从句却可用though， although来引导，而不能用 as 来引导.也就是说，although引导让步状语从句时不能倒装，as引导让步状语从句时必需倒装，而 though引导让步状语从句时可以倒装也可以不倒装.如：虽然很晚了，但我们还是继续工作.正：Late as ［though］ it was，we still went on working.正：Though it was late，we still went on working.误：Late although it was，we still went on working .误：As it was late，we still went on working.2）上面提到的倒装结构有时也可用来暗示原因，区另外法子主要看句子的内容：让步从句的内容年夜大都与主句在意义上相反，而原因从句则与主句之间有因果关系.比力：Tired as he was，he sat up late studying at night. 昨晚他虽然很疲倦了，但还是学习到很晚才睡.(表让步)Tired as he was，he went to bed early. 因为很累，所以他睡得很早.(表原因)Young as he was，he was equal to the task. 他虽年轻，却能胜任这项工作.(表让步)Young as he was，he was not equal to the task. 他因为年轻，所以不能胜任这项工作.(表原因)3）在美国英语中，人们通经常使用 as...as 引导让步状语从句.如：Cold as it was， we went out.=As cold as it was， we went out. 尽管天气冷，我们还是出去了.Successful as he is， he is not proud.=As successful as he is，he is not proud. 他虽胜利了，但不骄傲.二、as 引导定语从句as 的用法:(as 引导定语从句, 在定语从句中作主语、宾语、表语)(一) 如为限制性的，多用于the same …as ; the same as；such …as …; as many/much as；so …as等结构中.如：1. I have the same book as you (have). 我有一本和你的一样的书.Her attitude to him was quite the same as it had always been. (关系代词as和指示代词same连用, 在从句中用作表语, 先行词是same.)2.---Why didn't you mention that in face of the police just now?--- I thought it was such a minor detail as was hardly worth mentioning.We will only discuss such problems as have something to do with our own interests.Don't do such things as you are not sure about.There is no such place as you dream of in all this world.比力：I live in the same house that he used to live in.I'm wearing the same shirt as you wore yesterday.比力：Here is so big a stone as no one can lift. （定语从句）Here is so big a stone that no one can lift it.（结果状语从句）(二) 如为非限制性的，多独自引导一个定语从句，这种定语从句可置于句首，句中或句尾，译为"正如，这一点".（动词常为know, see, expect, point out, etc.）1. As we all know, smoking is harmful to one's health . (as 作宾语)=As is known to all, smoking is harmful to one's health . （as 作主语）=It's known to all that smoking is harmful to one's health .或:Smoking is harmful to one's health , as we all know .（as 作宾语）或: Smoking, as we all know, is harmful to one' health.2.He was a foreigner, as I knew from his accent. (宾语, 先行词是前面整个句子)领先行词被the same所修饰时，关系词既可以用as，也可以用that.在暗示具体事物时，有时两者有一定的区别.一般说来，暗示同一种类多用as，暗示同一事物多用that.如：This is the same instrument that I used yesterday. 这就是我昨天用过的那台仪器.This is the same instrument as I used yesterday. 这台仪器跟我昨天用过的那台一样.在笼统概念上，同种类和同一事物是没有绝对区另外，所以两个词可换用：I have the same opinion as / that you have.这里要注意的是：（1）使用as时，它引导的定语从句中的动词可以省略，但使用that时，定语从句中的动词不成省略.如：Women received the same pay as men.Women received the same pay that men received.(2) 在“the same…that”结构中，that只是用来加强语气，强调“相同”.that可以省去而不改变句子原意，甚至连名词前的same也可以省去.如：This is the same instrument that I used yesterday.= This is the same instrument I used yesterday.= This is the instrument I used yesterday.但在“the same…as”结构中，same和as都不能省略.(3) 当“the same…that”结构中的that作为关系副词用时，不成以直接与as互换.如：He lives in the same building that I live.= He lives in the same building as / that I live in.Shall we meet at the same place that we last met?= Shall we meet at the same place that / as we last met at?7. 领先行词前有such, so, as时，关系词应当用as.如：A wise man seldom talks about such things as he doesn’t understand.He spoke in such easy English as everybody could understand.At this time of the day, all buses and trolleys have to carry as many passengers as they can.It is so easy a book as every schoolboy can read.Let’s discuss such things as we can talk of freely.另需注意：This book is written in such easy English as beginners can understand.（定语从句）This book is written in such easy English that beginners can understand.（结果状语从句）。

1 as引导的从句崔长平河南省遂平中学（463100）在英语中，as作为一个常见的从句引导词，其用法和意义十分活跃而丰富，若不加以区分，很容易造成混淆。
现将其主要用法归纳如下：1）引导时间状语从句①在as引导的时间状语从句中，谓语动词既可以是延续性的也可以是非延续性的；有时从句的谓语动词也可用进行时形式。
②as引导的时间状语从句常可用来强调主、从句中的动作同时发生或伴随发生，常译作“随着……”，“一边……一边……”，“一……就……”等。
③在省略句中，as之后经常放置一个名词或名词词组。
I heard the murmur of their voices as I crossed the hall. A look of surprise came into Alison’s eyes as she read the message. Scott became nervous as he saw her face. Just as he was speaking there was a loud explosion. He smiled as he passed. As she sang，the tears ran down her cheeks. We get wiser as we get older. As a young man，he was a store keeper and later a postmaster.2）引导让步状语从句象although，though，while一样，as也可以用来引导一个让步状语从句，意为“尽管，虽然”， as引导的这种让步状语从句语气比较强，语体正规，经常用于书面语言，但as引导的让步状语从句须倒装。
其倒装要求如下：①表语＋as＋主语＋系动词（表语经常是由形容词、分词、或名词充当；名词用作表语时，其前不能加用冠词。
） Young as he is，he is equal to the task. Crowded as the restaurant was，they tried to find a table. Child as he was，he knew what was the right thing to do. ②状语﹢as﹢主语﹢谓语动词（这一结构中的谓语动词一般是行为动词，既可以是及物动词（带宾语）也可以是不及物动词。
） Hard as he studied，he did not get good marks in the exam. Early as we got there，our teacher was there before us. Much as I admire him as a writer I don’t like him as a man. ③动词＋as ＋主语＋……（在这一结构中，主语后面一般加上情态动词may，might，will，would，can，could等，句首的动词应该保持原形。
如果从句中没有情态动词，那么，应在从句的主语之后（根据时态和数的要求）加上助动词do、does或did。
在这一结构中，放在句首的动词如果是及物动词，那么，这个动词连同它的宾语一起放到as之前。
） Search as they would，they could find nothing in the house. Try as he may，he will fail in the examination. Die as he did，his inspiration lived on. Lose money as I did，I got a lot of experience.3）引导原因状语从句 as引导原因状语从句时，语气不及because强烈，它接近于since，now that，一般译作“既然，由于”之类的意义，只是“附带说明的理由”，表达一种说话人和听话人“共知的原因”。
as引导的原因状语从句一般置于主句之前。
As all the seats were full he stood up. As Davidson had a passion for walking，we started off on foot. As you are sorry，I’ll forgive you. It is very difficult for us to know what to do as we are not his parents.4）引导方式状语从句 as引导方式状语从句时，只修饰和说明主句的谓语动词，表示“按照，依照”、“用什某么方式或方法”；as只起引导词的作用，一般不在从句中充担成分；从句一般应置于主句之后，有时也可置于主句之前。
She cooks fish as my mother does. We must do as the Party tells us to. We should learn a foreign language as Marx did. As you like maths，I like biology. As a man lives，so he dies. When at Rome do as the Romans do.5）引导表语从句 as有时可以用来引导一个表语从句，意为“像……的样子（那样）”。
Things were almost as they had been before. His rooms were exactly as he had left them. The cottage is just as it was in Shakespeare’s time. ▲有时可以用来表示比例关系：2 is to 4 as 8 is to 16.（2﹕4 ﹦8 ﹕16）6）引导比较状语从句 as可以构成“as … as …”结构，表示“原级比较”或“加强语气”，意为“象……一样”、“……达”。
在这一结构中，第二个as引导的是一个比较状语从句。
这一从句经常使用省略句。
You know as much about that as I do. I haven’t done as much as I should have liked. Martin was as impatient as he was stubborn. He considered her opinion as valuable as any of ours. Waves of red lightare about twice as long as waves of blue light. She can run as fast as 20 miles an hour. The newly-built bridge is as long as 800 meters.7）引导补充说明性从句在leave … as they / it be 句型中，as引导的是一个补充说明性从句，具有宾语从句的作用。
本句型意为“使……处于原有状态”。
注意前后时态的呼应和数的一致。
Please leave things as they are. We left all the books as they were. We should leave nature as it is.8）引导限制性定语从句若限制性定语从句的先行词接受the same 或such修饰时，我们通常要使用as 来引导定语从句，as在从句中可以充当主语、宾语或表语。
定语从句可以是一个省略句。

Robbie looked just the same as ever.3 We are now in the same position as at the end of last summer.9）引导非限制性定语从句 as 引导非限制性定语从句时，意为“象……一样”，定语从句不修饰限制具体的引导词，而是对整个主句或主句中的某一部分进行概括性说明或评价，表明说话人对话语内容的的态度，as在从句中可以充当主语、宾语或表语。
as引导的非限制性定语从句可以置于主句之前、插入到主句之中，也可以放在主句之后，还可以使用省略句。

具有概括性含义。
which 引导的非限制性定语从句，可以修饰限制主句中的某一个名词或代词（有具体的先行词），也可以修饰说明整个主句或主句中的某一部分。
which引导的从句一般置于主句之后或置于被修饰限制的部分之后，但不可置于主句之前。
which常在从句中作主语、宾语、表语或定语等成分。
