状语从句 英语

状语从句 英语

状语从句英语英语中的状语从句(AdverbialClauses)是一种复合句,语法上可以分为状语性从句和从句状语。

前者是由状语来引导的从句,其句子结构是“主句+状语从句”,而后者则指状语从句中的状语作用。

状语从句在英语中的使用非常普遍,它们可以用来描述时间、原因、条件、结果、目的、让步、比较和强调等。

一般来说,英语中主要有八种语法结构可以用来构成状语从句,它们分别是when, while, since, if, unless, after, although, as。

其中,when状语从句用来表示时间,while状语从句表示转折或对比,since状语从句表示原因,if状语从句表示条件,unless状语从句则是将if状语从句的否定意义变成肯定意义,after状语从句表示时间先后,although状语从句表示转折,as状语从句可以表示时间、原因、结果等各种状语作用。

状语从句中的关键词(例如when, while, if)称为状语从句的关联词,它们可以给状语从句定义特定的意思,因此在英语句子中状语从句的关键词(关联词)也是至关重要的。

例如:He called me as soon as he arrived.这句话中,as soon as是一个状语从句,它表示到达后不久就打来了电话,因此,其中的关键词as soon as是这个句子的关联词,它起到了定义这个句子的意思的重要作用。

除了关键词(关联词)之外,状语从句中的动词也同样起着重要的作用。

根据句法规律,状语从句中的动词主要分为持续性动词(如be, stay, live)和瞬时性动词(如come, do, get)。

持续性动词则指表示某种状态或结果的动词,它们在状语从句中表示永久性的描述;而瞬时性动词则指表示某种动作的动词,它们在状语从句中表示一次性的动作或行为。

例如:He went to school while it was raining.这句话中,while it was raining是一个状语从句,它表示的意思是“下着雨的时候他去上学了”,而其中的动词was raining是一个持续性动词,它表示的是下着雨的情况持续到了他去上学的那一刻。

状语从句及练习附答案

状语从句及练习附答案

状语从句(adverbial clause)复习要点:掌握句法功能,记住连接词语法意义:状语从句是复合句中的一种,整个从句作主句的状语,修饰主句中的谓语动词、形容词、或副词。

置于句首时,状语从句后面一般要有逗号隔开;如果状语从句置于句尾,则从句一般不用逗号。

按照所作的状语和意义可分为时间、地点、原因、目的、结果、条件、让步、方式和比较等九种状语从句。

具体如下:一、时间状语从句(Adverbial Clauses of Time)时间状语从句通常由when,whenever,as,while,before,after,assoon as,since,once,no sooner...then,hardly/scarcely...when,tiLl/until 以及the moment,directly,immediately,the second,thefirst time,next time,every time,等引导。

1.由when,as,while 引导的状语从句:1)when 引导时间状语从句,表示当···,其谓语动词可以是延续性的,也可以是非延续性的,其作用最广泛。

When spring comes,trees turn green,When it rains,I usually go to work by taxi.When we were having lunch,the light went out.I will ring you up when I return.When she pressed the button,the lift stopped.He was eating his breakfast when the doorbell rang.be about to do...when...“就在那/这时,(突然)另一个动作发生了,在这儿只能用when。

定义:在复合句中,用来充当状语的句子称为状语从句。

功能:它主要用于修饰句子中的谓语动词、形容词或副词等,有时修饰整个句子。

位置:状语从句的位置较活:可以放在主句之前,用逗号与主句隔开;也可以放在主句之后,一般不用逗号。

由于它是从各个方面来修饰、说明谓语动词发生时的各种情况,所以常见的状语从句有九种之多。

各种不同的状语从句所使用的关系词也各不相同。

一、时间状语从句:1、引导词:A: 常用连词有:when, while, as, before, after, since, once, till, untilB: 特殊引导词:as soon as, the moment ,hardly…when…, scarcely…when…, no sooner…than…,by the time, the minute, the instant, immediately, directly, every time等。

二、知识网络结构图时间状语从句在句子中起时间状语作用的句子称为时间状语从句,可放在句首、句中和句尾.●when、while和as的用法三个词都可引导时间状语从句,意为"在......时候",但具体用法不尽相同.1. When既可引导一个持续动作,也可引导一个短暂动作,可用于主、从句动作同时发生,也可用于从句动作先于主句动作.I saw Mary when I was walking along the street 我沿大街走时看见玛丽了.1'11 phone you again when 1 get home.我到家后再给你打电话。

2. while引导的从句动词必须是延续性的,作并列连词,意思是"而,却"表对比、对照关系.考例:(1)—1'm going to the post office.—_______ you're there, can you get me some stamps?A. AsB. WhileC. BecauseD.

状语从句

状语从句

状语从句状语从句有九大类,分别可以表示时间、地点、原因、目的、结果、条件、让步、比较和方式。

尽管数目较多,但理解起来并不难。

从本质上讲,状语从句就是用不同的连词讲几个分句连接起来,以表达分句之间特定的逻辑关系。

一、时间状语从句从本质上讲,时间状语从句就是用来说明主句动作与从句动作发生时间上的先后关系。

要注意两点:1.注意主句、从句的时态搭配关系。

对于不同时间状语从句的连接词,这种搭配关系是不同的。

2.注意主句、从句的谓语动词的延续性和短暂性。

翻译下面两个句子:1.I was telephoning Harry when shearrived2.I telephoned Harry when she arrived.分析:句1中telephoning 先发生,arrived后发生。

此时,telephoning是一个延续性动作,arrived是一个短暂性动作。

句2中telephoned变成了短暂性动作,这里telephoned后发生,而arrived 先发生。

译文:1.她到的时候,我正在给哈利打电话。

2.她到了以后,我给哈利打了一个电话。

英语状语从句的用法归纳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。

(一)时间连接词when, while, as 的用法when,while,as显然都可以引导时间状语从句,但用法区别非常大。

一、when可以和延续性动词连用,也可以和短暂性动词连用;而while和as只能和延续性动词连用。

①Why do you want a new job when you've got such a good one already?(get为短暂性动词)你已经找到如此好的工作,为何还想再找新的?②Sorry,I was out when you called me.(call为短暂性动词)对不起,你打电话时我刚好外出了。
