as引导的五种状语从句
as作从属连词用时,可以引导五种状语从句。现归纳如下：
1. as表示“当……的时候”,引导时间状语从句,多强调主句和从句中的动作或状态同时发生,从句可放在主句前,也可放在主句后。例如：
As I waited at the stop, I heard a big noise. 当我在车站等车的时候,我听到一个很大的声响。
She rose up as he entered. 当他进来时,她站了起来。
2. as表示“因为”、“由于”,引导原因状语从句,其语气不如because强,通常为附加说明的理由,且是已知晓的原因,主句与从句没有逻辑上的因果关系。例如：
As she was not well, I went there alone. 因为她身体不好,所以我独自到那里去了。
As he is a tailor, he knows what to do with this material. 由于他是个裁缝,他知道怎样利用这块布料。
3. as表示“虽然……但是……”,引导让步状语从句,从句通常用倒装语序,把从句的表语、状语或动词原形放在as前面,可以用though替代。例如：
Child as he is, he knows a lot. 虽然他是个孩子,但他知道的东西很多。
Hard as it was raining, they went on working in the field. 虽然天下大雨,但他们继续在田地里干活。
4. as表示“按照”、“依照”、“像”,引导方式状语从句,从句置于主句之后。例如：

The absence of air also explains why the stars do not seem to twinkle in space as they do from the earth. 空气的不存在,也说明了为什么在空中星星看来并不闪烁,而不像从地球上看的那样。
5. as表示“像……一样”,引导比较状语从句,对主句和从句的动作或状态加以比较,说明它们之间有相似之处,在从句中常省略与主句相同的部分。例如：
He doesn't work as hard as I (do). 他不像我工作那样努力。
I hope the necklace was as good as the one you lent me.我希望我挂项链同你借给我的一样好。

as引导的时间状语从句
as引导的时间状语从句 as是高中英语中非常重要的一个词汇，它的用法非常的复杂，且在每年的高中英语考试中占有非常重要的位置。其中as引导的时间状语从句尤为复杂，本文以as在引导时间状语从句时的三种不同意义为线索，细致讲述as引导时间状语从句这一语法知识点。 as引导时间状语从句表示"当....时候" as在表示"当....时候"的意义时，与"while"引导时间状语从句有一个共同点，就是此时从句的谓语动词一定要用表示延续性的动词。 例句1：She stayed up late writing her paper while our kids and I were sleeping. 当我和孩子们在睡觉的时候，她在熬夜写论文。 注释：这个句中while引导的时间状语从句的谓语动词是表示延续性的"were sleeping"。例句2：They all finished their homework, as I was playing with my dog. 当我在和我的小狗玩耍的时候，他们都完成了家庭作业。 注释：从句中的谓语动词"was playing"是表示延续性的动词。 as引导时间状语从句表示"一边...一边..." 当as表示"一边...一边..."引导时间状语从句时，主句和从句的动作同时发生，此时从句的谓语动词没有要求。 例句1：As she explained her misfortunes, she wiped tears off her cheeks. 她一边讲述着自己的不幸遭遇，一边擦去脸上的泪水。 例句2：She cried as she walked alone on the dark road. 她一边独自走在黑暗的小路上，一边哭泣。

as引导的从句用法
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.

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.

SDN让步状语从句 让步状语从句是状语从句中的一种，其本身也是状语从句。一般翻译为“尽管……”或“即使……”，就是我们日常生活中用的“退一步说……”的感觉。 引导让步状语从句的连词主要有以下这些：though,although,while,as; even if,even though; whether...or...; no matter+疑问词，疑问词-ever，regardless of+名词/名词短语/名词从句，despite，in spite of。切记although，though 不可与but连用，但可以与still和yet连用。 ⑴though,although表示“虽然，纵然”之意。 这两个连词意思大致相同，在一般情况下可以互换使用。在口语中，though较常使用，although 比though正式，二者都可与yet,still或never，the less连用，但不能与but连用。例如：My will remains firm though I must lower my physical sights. 尽管我得降低体育（锻炼）的目标，但我的意志是坚强的。 Though I believe it,yet I must consider. 尽管我相信这一点，但我还得考虑考虑。 Although/Though he was exhausted,(still) he kept on working. 虽然他已经精疲力竭了，但仍然继续工作。 Although/Though he is very old,(yet) he is quite strong. 他虽然年纪大了，身体还很健壮。 值得注意的是，although引导的让步状语从句位于主句之前的情况较多，though引导的让步状语从句可位于主句之前或主句之后。例如： She passed the examination though she had not studied very hard. 她虽然不用功学习，考试却及格了。 ⑵as,though表示“虽然……但是”，“纵使……”之意。 as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中，但although不可以这样用。例如： Object as you may,I’ll go.(=Though/Although you may object,I’ll go.) 纵使你反对，我也要去。 Hard as/ though he works,he makes little progress. (=Though he works hard,he makes little progress.） 尽管他学习很努力，但几乎没取得什么进步。 Child as/though he was,he knew what was the right thing to do.（=Though he was a child,he knew what was the right thing to do.） 虽然他是一个孩子，但他知道该做什么。 Fast as you read,you can’t finish the book so soon. 纵然你读得快，你也不能这么快读完这本书。 Lover of towns as I am ,I realize that I owe a debt to my early country life. 尽管我爱城市，但我知道，以往的乡村生活使我受益匪浅。 Small as atome are,they are made up of still samller units. 尽管原子很小，但它们由更小的单位构成。 ⑶even if,even though 表示“即使……”，“纵使……”之意，含有一种假设。 这两个复合连词的意思基本相同。它们常互换使用，但意义有细微差别。even if引导的让步从句含有强烈的假定性，可用来表示与事实相反的假设，但不能用来描述已经发生的事实。而even though引导让步状语从句时，是以从句的内容为先决条件的，即说话人肯定了从句的事实，表示已经发生了的事。例如： We’ll make a trip even if/though the weather is bad. 即使天气不好，我们也要作一次旅行。 Even if he is poor,she loves him. (=He may be poor,yet she loves him.）
As引导的各种从句归纳
As引导的从句 一、As引导让步状语从句 为了帮助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，但他并不幸福。 Child as he is，he knows to help other. 他虽是个孩子，却知道帮助别人。 【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。比较： 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 he is 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. 他虽然成功，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。
as引导让步状语从句时的倒装
as引导让步状语从句时的倒装 as作“虽然”解，引导让步状语从句时，必须将表语、状语或动词原形提到as前面。经常遵循“形容词/副词/（不带冠词的）名词/动词原型＋as/though＋主语＋谓语”结构。（though有时也可像as这样使作倒装。）如： Tired as I was, I tried to help them.虽然我很累，我还是努力帮助他们。 Try as he would, he couldn’t open the door.他试过多次了, 却仍打不开那门。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。 Hard as (though)they tried, they couldn’t make her change her mind. 尽管他们做了很大努力，却没法让她改变主意。 Boy as he was, he behaved like a girl.他虽是个男孩，但举止却像个女孩。 “疑问词+ ever ”可分为两类，“疑问代词+ ever ”：whatever / whichever / whoever （宾格whomever ）和“疑问副词+ ever ”：wherever / whenever / however. 不论是“疑问代词+ ever ”还是“疑问副词+ ever ”，其意义都是“不管/ 无论+ 该疑问词的本义”。 1.“疑问代词+ ever”可引导两种类型的从句，即让步状语从句和名词性从句（主语从句、宾语从句）。 （1）引导让步状语从句。此时whatever / whoever / whichever 分别等于“no matter + what / who / which”。例如： Whoever says so, it is wrong.= No matter who says so, it is wrong. 注意：这类从句中应用一般现在时表将来，从句中也常用情态动词may / might . （2）引导名词性从句。这时whatever / whoever / whichever不能换成whatever / whoever / whichever例如： Whoever smokes here will be punished.（主语从句） Beggars will eat whatever they are given.（宾语从句）
as引导的从句
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
