状语从句用法讲解和练习

第章状语从句 学习指导 状语从句在句子中作状语,用来修饰主句或主句的谓语。一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比 较和方式。尽管种类较多,但由于状语从句与汉语结构和用法相似,所 以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词。现分别列举如下: 状语从句分九类: 在这一章节的学习中,要求同学们掌握各类状语从句基本概念,并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有:2.when,while,as均可表示“当……的时候”。 when强调“特定时间”,表示主句谓语动词的动作与从句谓语动词的动作是同时发生的,或从句的动作发生在主句的动作之前;while表 示的时间是一段,而不是一点,as多用在口语中,强调“同一时间”或“一前一后”,有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了,他想去旅游。 As spring warms the good earth,all flowers begin to bloom.(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生,但三者也有

区别。as和when引导的从句既可表示一点时间,也可表示一段时间,从句中的谓语动词既可以是持续性动词,也可以为短暂性动词,经常可以互换使用;while引导的从句通常表示一段时间,从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时,这三者可以通用(前面例句中已有体现),再如: 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心,因为小艾丽思病了,特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时,则多用as,可译为“一边......,一边......”。例如: He looked behind from to time as he went.他一边走,一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移,天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。(若表示两个短促动作几乎同时发生时,用as的场合多于when.) 当主从句之间表示转折或对比关系时,多用while, 不用as或when。如:

初中英语状语从句知识点总结.doc

初中英语状语从句知识点总结(一) 用来润饰主句中的动词,形容词或副词等而充任状语的从句叫做状语从句。 状语从句常用隶属连词来引导,与主句连接起来。若置于句末,则前面不加逗号。依据含义和效果,状语从句可分为时刻原因条件等几种。下面咱们就来剖析一下 这几种状语从句。 1 时刻状语从句 时刻状语从句常用隶属连词 when,after,until,as soon as, 等来引导。 当主句是祈使句或谓语动词是一般将来时态或神态动词时,其时刻状语从句 中的谓语动词常用一般现在时态表明将来产生的动作或存在的状况。这便是咱们 常说的“主将从现”。 如:Please call me when you get there. 当你到那时,请给我打个电话。 I will write to you as soon as I arrive in Beijing. 我一到北京就给 你写信。 <温馨提示>since 引导时刻状语从句表明“自从 , 以来”,从句中的动词一 般表明动作的起点,用曩昔时 ; 而主句的动作连续的状况则用一般现在时或现在 完结时。常用的句型为: It has been/is+ 一段时间+since+ 过去时。 如:I has been/is three years since we met last time. 自从咱们前次 碰头,现已三年了。 2 条件状语从句 引导条件状语从句的连词或词组有:if( 如果),unless( 除非),as long as( 只 要) 等。如果主句是将来时,条件状语从句也用一般现在时来表示。 如:I will stay at home if it rains tomorrow. 假如明日下雨,我就待 在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习,否则是学欠好英语的。 <温馨提示>由if 引导的条件状语从句,若从句表达的是与现在现实相反的 事实,则常用虚拟语气,即用过去时态表示( 如果涉及到be 动词,一律都用were)。此刻,主句则用曩昔将来时。

(完整)高中英语状语从句讲解及练习

状语从句 在复合句中作状语,位置灵活。 状语从句可分为时间状语从句,目的状语从句,条件状语从句,让步状语从句,地点状语从句,原因状语从句,方式状语从句,结果状语从句。 (一)时间状语从句 1.when, as, while a.when表时间,从句既可以用延续性动词,又可以用瞬间动词。 Eg: When I get there I will call you. 如果when引导的时状的主语与主句的主语相同,而从句的谓语又是be动词时,那么从句中的主语与be 可省。 Eg:When (you are)in trouble, you can ask her for help. 如果when引导的时状的主语与主句的主语相同时,往往可以用“when+分词”的形式代替该状从。Eg:When I came into the room(When coming into the room), I found the light was off. b.while表时间,从句需用延续性动词,或者主句的动作发生在从句的动作进行过程中。主句的谓语动词 通常是非延续性动词。 Eg: He came in while I was reading a book. I met her while I was in school. c. as表时间,与when相似,但侧重强调主从句动作同在时间点或同时间段进行。同时可表示主句的动作随着从句的动作的变化而变化。 Eg: He jumps as he sings. As the wind rose, the noise increased. 2.before(在……之前)与after(在……之后) Eg:See me before you leave. I saw them after I arrived. 3. till与until 肯定形式表示的意思是"做某事直至某时"。否定形式表达的意思是"直至某时才做某事"。 Eg: Wait till/untill I call you. 等着直到我叫你。 She didn't arrive till/until 6 o'clock.. 她直到6点才到 但是置于句首时只可用untill.
