as既可以用作连词,引导多种状语从句,也可以用作关系代词引导定语从句,其用法繁多复杂。
现将as从句小结以方便于同学们掌握。
1.引导时间状语从句,作"当……的时候",其特点为: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 dances as she sings on the stage. 这个孩子在舞台上载歌载物。
He looked behind from time to time as he went forward. 他边走边不时地回头看。
2)表示两个同步发展的动作或行为,译为"随着……"。
如:As time went on / by, she became more and more worried. 随着时间的流失,她越发担心。
As children get older, they become more and more interested in the things around them. 随着年龄的增长,他们对周围的事物越感兴趣。
3)表示两个短促行为或事件几乎同时发生。
如:I thought of it just as you opened your mouth.Just as the flying worm hit her face, she gave a loud cry.4) 后接名词表示某一年龄段时,用as。
如:As a young man(=When he was a young man), he was active in sports. 年轻时,他在运动上很活跃。
注意与when、while的用法区别: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。
如:When he was at college, he could speak several foreign languages. 他上大学时能讲好几门外语。
When the clock struck twelve, all the lights in the street went out. 当钟敲响12点时,街上所有的灯都熄灭了。
2)while从句中的动词是可延续性动词,表示一段较长的时间或一个过程,主句动作与从句动作同时进行或在从句动作过程中发生。
如:Work while you work. Play while you play. 工作时工作,娱乐时娱乐。
2.引导原因状语从句作"既然"、"由于"解,相当于since,常用来表示已为人们所知或显而易见的原因或理由。
如:As you're not feeling well, you may stay at home. 既然你身体不好,你还是留在家里吧。
注意与because,since的差别:because表示的语气最强,表示一种直接的原因;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";而as在引导原因状语从句时一般放在句首,语气较弱,较口语化。
例如:He will succeed because he is in earnest.他一定会成功,因为他很认真。
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。
As rain has fallen, the air is cooler. 因为下过雨,空气比较清爽。
3. 引导方式状语从句作"像"、"按照……的方式"解。
如:You must do everything as I do.你必须要照我的样子去做。
She stayed in bed as the doctor had told her. 她依照医生的吩咐卧床休息。
Leave it as it is.把它维持原状好了。
注意与as if, as though的区别。
as though/if引导方式状语从句时的含义是“好像、似乎”。
如果从句所表示的情况是事实或具有很大的可能行,从句中通常使用直陈语气;如果as if从句描述的是非现实的情况或纯属假设,从句则应使用虚拟语气。
另外,as if引导的从句有时用省略形式,一般是省略和主句相同的主语和动词be。
例如:He always talks to me as if he were my brother. 他总是以哥哥的口气跟我说话。
The boy is running here and there as if (he were) searching for something lost on the sports ground. 这个孩子跑来跑去,好像是在找丢在操场上的东西似的。
He acts as if (he were) a fool.他表现得像个傻子。
4.引导比较状语从句。
在as...as...或not so/ as...as...中,前一个as是副词,后一个as是连词,它所引导的比较状语从句多使用省略形式。
如:They helped the old man as often as (it is) possible. 他们尽可能经常地帮助那位老人。
I don't speak English so/ as well as he ( speaks English). 我讲英语没有他那么好。
几个关于as...as的常见句型:1) as...as possible (等于as … as sb. can/ could)Please answer my question as soon as possible.请尽快回答我的问题。
2) as...as usual/beforeShe looks as pretty as before.她看起来和以前一样漂亮。
另外,一些as...as结构也常作为习语而使用:as busy as a bee像蜜蜂一样忙碌as easy as ABC 像ABC一样容易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5. 引导让步状语从句as引导的让步从句必须是倒装的形式,倒装的形式是:1)提前表语(单数可数名词做表语时要省略冠词)2)提前状语3)提前动词原形。
例如:Child as he was, he knew what was the right thing to do. 尽管他是个孩子,他却知道什么是该做的事情。
Try as he might, he failed in the exam. 尽管他努力了,可还是考试没及格。
Much as I like it, I can’t afford the laptop. 虽然我非常喜欢这部笔记本电脑,我却买不起。
注意与though和although的区别:although 和though也可以引导让步状语从句,含义是“虽然,尽管”,但as所表示的语气较强,引导的让步状语从句用倒装语序;although语气稍正式些,它所引导的从句可放在句首,也可放在句中,主句中不能再用but,但可以用yet,它所引导的从句不能倒装;though引导的让步状语从句最为常用,它所引导的从句既可和as从句一样倒装,也可以使用正常语序。
另外though和although所引导的从句在主句的主语和从句的主语一致,且从句的谓语动词有be时,从句的主语和be动词可以省略。
例如:Although he is quite old, he still jogs every day.百度百科里有哎。
讲的还蛮清楚的方式状语从句常见的引导词有表示“像……”的as和表示“好像……”的as if/as though,例如:Let’s study as Lei Feng studied. 让我们像雷锋那样学习吧。
// Think as I think. 像我这样去想。
// He talks as if/though he is drunk.从他谈话的样子来看他好像醉了。
1. 方式状语从句通常由as, (just) as…so…, as if, as though引导。
1)as, (jus t) as…so…引导的方式状语从句通常位于主句后,但在(just) as…so…结构中位于句首,这时as从句带有比喻的含义,意思是"正如…","就像",多用于正式文体,例如:Always do to the others as you would be done by. 你希望人家怎样待你,你就要怎样待人。
As water is to fish, so air is to man. 我们离不开空气,犹如鱼儿离不开水。
Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样,我们也要扫除我们头脑中落后的东西。
2)as if, as though 两者的意义和用法相同,引出的状语从句谓语多用虚拟语气,表示与事实相反,有时也用陈述语气,表示所说情况是事实或实现的可能性较大。
汉译常作"仿佛……似的","好像……似的",例如:They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实,就仿佛它不存在似的。
(与事实相反,谓语用虚拟语气。
)He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。
(与事实相反,谓语用虚拟语气。
)It looks as if the weather may pick up very soon. 看来天气很快就会好起来。
(实现的可能性较大,谓语用陈述语气。
)说明:as if / as though也可以引导一个分词短语、不定式短语或无动词短语,例如:He stared at me as if seeing me for the first time. 他目不转睛地看着我,就像第一次看见我似的。
