那状语从句具体要怎么使用呢?以下是由店铺整理关于状语从句的用法的内容,希望大家喜欢!状语从句的用法一、概说按照其意义,状语从句可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句等。
状语从句是高中英语学习中的一个语法重点,也是历年高考重点考查的内容之一。
学习状语从句主要应注意引导状语从句的从属连词的用法与区别,以及从属连词在一定的语言环境中的意义与用法。
二、时间状语从句1. 引导时间状语从句的从属连词很多,常见的有before, after, when, while, as, since, till, until, as soon as 等。
2. 表示“当…时候”的 while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用when;当表示“一边…一边…”或“随着”时,只能用 as。
另外,用于此义的 as 所引导的时间状语从句谓语只能是动作动词,不能是状态动词。
如下面一道高考题的答案是 B 而不能是A:“I’m going to the post office.” “_____ you’re there, can you get me some stam ps?”A. AsB. WhileC. BecauseD. If3. until 在肯定句中通常只连用延续性动词,表示相应动作结束的时间;在否定句中通常连用非延续性动词,表示相应动作开始的时间,意为“直到…才”。
如:He waited until she was about to leave. 他等着一直到她准备离开。
I did not begin to work till he had gone. 他走了后我才开始工作。
4. 表示“一…就”除用 as soon as 外,还可用 the minute, the second, the instant, immediately, directly, instantly, no sooner…than, hardly…when 等。
高中英语语法系统讲解之十一状语从句状语从句在句中作状语,修饰主句中的动词、形容词或副词等,有时修饰整个主句。
状语从句放在主句之前时,常用逗号分开;放在主句之后,一般不用逗号。
状语从句按其意义和作用分为时间、条件、原因、让步、目的、结果、方式、比较、地点等9种。
1. 时间状语从句时间状语从句可放在句首、句中或句尾。
常用when,while,as,after,before,since,until,once,as soon as,the minute / moment“一……就……”,hardly … when,no sooner … than“刚……就……”等连接词引导。
○1连词when,while,as都表示“当……的时候”,但是when引导的从句的动作和主句的动作可以同时发生,也可以先后发生;用as,while时则强调主句和从句的动作同时发生。
如While I was reading, he came in.As he walked along the street, he sang happily.但当从句表示“随时间推移”时,只能用连词as,不能用when或while。
如As time goes on, I like to speak English more and more.○2从属连词as soon as,immediately,directly,the moment,the minute,no sooner … than …, hardly / scarcely … when …,once引导的从句都表示从句的动作一发生,主句的动作随即就发生,意为“一……就……”,从句中用一般时态代替将来时态。
如Once you remember it, you’ll never forget it.The moment I heard the voice, I knew father was coming.No sooner had we arrived at the station than the train left.温馨提示:as soon as,the moment引导的从句表示“一……就……”;no sooner … than …,hardly … when引导的从句表示“刚……就……”。
高中英语语法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……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, as; even if, ev en though; whether...or...; no matter+疑问词,疑问词-ever。
下面对这些连词引导的让步状语从句作一说明。
(1)though, 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nevertheless连用,但不能与but连用。
例如:Although/Though he was worn out, (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,thoug h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。
(2)as, 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间或也用于这样的结构中,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。
高中英语语法:状语从句篇一、时间状语从句1、when的用法(1)when既可引导一个持续性动作,也可引导一个短暂性动作,可用于表示主句和从句动作同时发生或从句动作先于主句动作,有时还可表示从句动作后于主句,意为“当。
时候”。
(2)when在be about to do......when......,be doing.....when.....,had done。
when。
,be on one’s way。
when。
,be on the point of doing。
when。
等结构中,作“那时突然”讲。
(3)when “既然、鉴于;尽管,虽然(位于主句之后);如果”2、while的用法(1)表示“当。
时候”,引导的动作必须是延续性的。
(2)用作并列连词,表示相对关系“然而”。
(3)引导让步状语从句,相当于although,意为“虽然”,位于主句前。
(4)引导条件状语从句,相当于as/so long as,意为“只要”。
3、as 的用法(1)表示“当。
时候”,强调同时发生,不指先后。
