英语中的九大状语从句状语从句在主从复合句中修饰主句中的动词、形容词或副词等,按意义可以分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。
一.时间状语从句。
通常由从属连词when, whenever, as, while, before, after, as soon as, till, until, since, once (一旦), hardly……when…, no sooner…….than…; 等引导。
例如:The cyclist started just as the lights changed to green.Whenever we met with difficulties , they cam to help us.He didn’t leave his office until he had finished the day’s work.应注意的问题1.在时间状语从句中,通常要用动词的一般现在时态表示一般将来时态,用一般过去时态表示过去将来时态。
但when 引导一般疑问句或名词性从句时不受上述语法规则的限制,因此,应该加以区分。
例如:When China will enter WTO depends on the bilateral (双边的)joint efforts.Once you understand the rules of the game, you’ll enjoy it.2.when , while, as 的不同用法。
一般说来,当主、从句的动作是同时发生的事,三者可以换用。
when 既可以引导一个持续动作,也可以引导一个短暂动作,可用于主句和从句动作同时发生或从句动作先于主句动作;while 引导的动作必须是持续性的,强调主句和从句的动作同时发生,往往侧重主句和从句动作的对比;as 用于引导“在某行为的继续中发生某事”的“继续之行为”,所以多与过去进行时连用,翻译成“一边……一边……”或者表示动作的变化,翻译成“随着……”。
状语从句一.分类:when (当……的时候) while (在……期间) as (当……的时候, 一边……一边……)before (在……之前) since (自从……以来) till/until (直到) hardly…when… (刚……就) as soon as (一……就……)after (在……之后) not…till/until(直到……才)no sooner…than…(刚……就)地点状语从句:where (在那里) wherever(无论哪里)原因状语从句:because (因为) since (因为,既然) as (由于) for (为了) now that(既然)目的状语从句:(so)that=in order that(以便)so as (not)to (以便[不])in case(以免)lest(以免)结果状语从句:so+adj./adv.+that(如此……以致)so that(结果……)such+n.+that(如果……以致)that(所以,因此)让步状语从句:though/although不可同but连用。
though/although (虽然)however (可是)even though(即使)even if (即使)no matter+what/which/where/who/when =whatever/whichever/wherever/whoever/whenever(不论什么/哪一个/哪里/谁/何时)比较状语从句:as (正如)as…as(和……一样)not as/so … as (不如……)than(比……更)the+比较级…+the+比较级(越……越……)条件状语从句:if(假设)unless(如果不)so long as(只要)on condition that (如果)方式状语从句:as(像……那样地)just as(正像)as if(好像)as though(好像)二.各种状语从句的简化方法:1例:After she sang,she left the rich man's house.= After singing,she left the rich man's house.2.以as soon as引导的状语从句的主语若与主句主语一致时,从句等于on+doing sth.,作状语,此时的动词为非延续性动词。
1状语从句状语从句一.分类:种类连接词注意区别:when/whenever/while/as/before/after/instantly/until/till/by the time/as soon as/hardly when/directly/no sooner than/the moment/the minute/immediately有一些表示时间的名词短语也可用来引导时间状语从句: the minute, the moment, every time, the first time时间例: The moment he reached the country, he started his状语search. 他一到达这个国家,就开始他的探寻工作。
有一些表示时间的副词也可用来引导时间状语从句:directly例: Directly the master came in, everyone was quiet.校长一进来,大家就安静下来地点状语where//wherever as 和 when、while :as, when 引导短暂性动作的动词。
当从句的动作发生于主句动作之前,只能用 when 引导这个从句,不可用 as 或while 。
从句表示 " 随时间推移 " 连词能用 as,不用when 或 while 。
till/until 和 not till/until:Until 可用于句首,而till 通常不用于句首。
where ,表示某一个;wherever ,表示任何一个。
原因状语Because/as/since/now that/for because 和 since、for 、as、now that :because 语势最强,用来说明人所不知的原因,回答 why 提出的问题。
当原因是显而易见的或已为人们所知,就用 as 或 since。
由 because 引导的从句如果放在句末,且前面有逗号,则可以用 for 来代替。
1.时间状语从句常用引导词:when, as, while, as soon as, before, after, since , till, until特殊引导词:the minute, the moment, the second, every time, the day,the instant, immediately , directly, no sooner … than, hardly …when, scarcely … whenI didn’t realize how special my mother was until I became an adult.While John was watching TV, his wife was cooking.The children ran away from the orchard(果园), the moment they saw the guard.No sooner had I arrived home ,then it began to rain.Every time I listen to your advice, I get into trouble.2.地点状语从句常用引导词:where特殊引导词:wherever, anywhere, everywhereGenerally, air will be heavily polluted where there are factories.Wherever you go, you should work hard.地点状语从句§4地点状语从句 (adverbial clause of place) 地点状语从句一般由连接副词where, wherever等引导,已经形成了固定的句型,例如:句型1:Where+地点从句,(there)+主句。
