时间状语从句常见的从属连词有:(注意其汉语意义)

when,while,as,before,after,since,until(till)onceassoonas,themoment,theminute,imm ediatelR,directlR,each/everRtime,thefirsttime,thelasttime,neRttime,bRthetime,whenever等。例如:EverR/Each timeIwasintrouble,hewouldcometomRhelp.

Ithoughtherniceandhonestthe first timeImether.

注意:(1)when,while,as的区别:

1)when引导从句时,主从句的动作有先有后,也可以同时进行,从句的动作可以是持续性的,也可以是短暂的。如:

WhenIgot totheairport,theplanehadalreadRtakenoff.(主先从后)(短暂性)

WhenIlived there,IusedtogototheseasideonSundaRs.(同时)(持续性)

Whenthemovieended,thepeoplewentback.(从先主后)

2)while侧重主从句动作的对比,且从句的动词必须是持续性的。如:

Whilewewerechattingshewaslookingatthetimetableonthewall.

3)as引导从句时侧重主从句动作同时或几乎同时进行,从句的动作可以是持续性的,也可以是短暂的。如:

SometimesIwatchTVasIamhavingbreakfast.

4)when和while还可以是并列连词,意思分别是“就在这时”,“然而”。如:

Iwashavingarestonthesofawhenthetelephonerang.

TheRweresurprisedthatachildshouldworkouttheproblemwhiletheR couldn’t.

注:并列连词when常用与以下句型中:

①…was/weredoing…when…(正在做…突然)

②…was/wereabouttodo…when…(刚要做…突然)

③…was/wereonthepointofdoing…when…(刚要做…突然)

④…hadjustdone…when….(刚一…就)

⑤HardlR/ScarcelR had…done…when…(刚一…就)

(2)before引导从句时,词义非常灵活,注意下列句子中的before的词义:

1.BeforeIcouldgetinaword,thetailorhadmeasuredme.(还没来得及…就)

2.Wehadn’trunamilebeforehefelttired.(还没…就)

3.Wehadsailed4daR sbeforewesawland.(…才…)

4.PleasewriteitdownbeforeRouforgetit.(趁还…没就)

(3)till(until)和not…till(until)

1)till(until):主句谓语动词必须是持续性的,意思是“到…为止“如:

Heremainedtheretill/untilshearrived.

2)not…till(until)…:主句谓语动词必须是短暂性的,意思是“直到…才”如:

Shewon’tgotobedtill/untilhereturnshome.

3)not…until还有强调式和倒装式:

强调句:Itisnotuntilhereturnshomethatshewillgotobed.

倒装句:Notuntilhereturnshomewillshegotobed.

(4)几个极易混淆的时间状语从句:

1)Itwas+时间点+when…(当的时候时间是)

Itwas5amwhenwearrivedatthevillage.

2)Itwas/willbe+时间段+before…(没过…就/过了…才)

Itwas/willbetwoweeksbeforewemet/meetagain.

3)Itis/hasbeen+时间段+since…(自从…以来有…)

Itis/hasbeen3Rearssincewelastmet.

突破点:一看be动词的时态,二看时间段还是时间点。

注意:在“Itis/hasbeen+时间段+since…”句型中,从句的动词必须是短暂性的,如果是延续性的动词,时间要从从句的动作结束时算起。如:

Itis3RearssinceIsmoked.(我戒烟有三年了)

补充:

assoonas,immediatelR,directlR,instantlR,themoment,theminute,theinstant,nosooner…th an…,hardl R/scarcelR….when….和once这些从属连接词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,常译为“一…就…”。从句中一般时态代替将来时态。everRtime,eachtime,neRttime,thefirsttime,anRtime,allthetime等名词短语用来引导时间状语从句,表示“每当…..,每次…..;下次……”等。

初中英语时间状语从句讲解及练习

语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同,可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样,状语从句的位置比较灵活。既可置于主句之前(通常用逗号与主句隔开),也课置于主句之后(不需要用逗号与主句隔开),有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生,这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续,具有at the same time的意思 他继续往下谈的时候,越来越兴奋。 as还可以表示一边??一边??,强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来,天气暖和起来。 ② when 强调动作点的特定时间,具有at the time that 的意思 当老师走进来的时候,我们都站起来了。 ③ while 表示较长的期间,具有during the time that 的意思 当我在这的时候,我很安全。 2.主句发生在从句之前,这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”,在否定句中意为“直到 --- 才”。从句既可置于主句前,也可置 于主句之后。 回家之前我必须干完所有的活。

语法讲解 时间状语从句的用法解析及练习

语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语,其位置较灵活,可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号,放在句末时状语从句前面往往不用逗号)。根据状语从句的含义,状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结,希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since,whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同,要注意把握不同的时间状语从句的引导词所表示的不同时间关系,以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析: (1) when引导时间状语从句时表示“当……的时候”,when既可以指时间段也可指时间点,从句中既可用延续性动词又可用非延续性动词,且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句:I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹,这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了,其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时,妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同,而从句的谓语又是be动词时,那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时,往往还可以用“when+分词”的形式替代该状语从句。例如:When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候,我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”,它强调主句的动作与从句的动作同时持续地进行,用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词,或者主句的动作发生在从句动作的进行过程中,主句中的谓语动词通常是非延续性动词,例如:Study while you study; play while you play. 该学习的时候就学习,该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时,一边……一边……”,侧重表示两个动作同时发生(包括一个主语同时进行两个动作),或者一种动作随着另一种动作的变化而变化。例如:He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

时间状语从句讲解和练习(答案)

时间状语从句 用句子表达一件事情或一个行为发生的时间,这个句子就叫时间状语从句。时间状语从句根据其所表示的时间不同,所使用的连词也不同。下面我们一起来看一下几个常见的时间状语从句: 1.when引导的从句:表示主句的动作和从句的动作同时发生,或从句的动作发生在主句动作之前。 例如:I was going out when a visitor came. (动词动作同时发生。)我正要出门,有客人来访。 I shall tell her the good news when she comes.她来时,我将告诉她这个好消息。 小试牛刀:I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get) 2.while 引导的从句:表示“当……过程中”,强调某一段时间内主句和从句中谓语动词所表示的动作在同一时期发生。由于while从句表示一个持续的行为,所以从句中要用持续性动词,并且持续性动词常用进行时态。例如:Keep an eye on my little sister while I am away.我不在时,请照看一下我的小妹妹。 While we were watching TV, Jim came in. 我们看电视的时候,Jim进来了。 小试牛刀:It started to rain. We were playing football.(while)_______________________________________ Lucy was cleaning the room Lily was listening to music. 3.as引导的时间状语从句:表示“当……的时候;一边……一边……;随着……”,其从句的主语与主句的主语往往是同一人或物。 例如:She sang as she worked. 她一边工作一边唱歌。=She was singing as she was working. I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。 小试牛刀:we walked, we talked. You will grow wiser you grow older. 4.before引导的从句:一般表示主句的动作发生在从句动作之前。 例如:I didn’t know any English before I came here. 我到这儿来之前,一点英语都不懂。 例如:I had written my report before my father came back. 小试牛刀:He bought the ticket he went to see the film. 5.after引导的从句:表示主句的动作发生在从句动作之后。 例如:After he locked the door, he left. 他锁上门后,就走了。 After he had finished his work, he played a game of chess with his friend. 他做完工作后,和朋友下了一盘棋。小试牛刀:I will go out to play basketball with you. I finish my homework.(after) _______________________ _ He left the classroom he had finished his homework the other day. 6.since引导的从句:表示“自从……以来”,从句中的动词一般表示动作的起点,用过去时。主句中的动词表示动作延续的情况,一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态,可用一般现在时。 例如:Since he met this good friend, he has made great progress in his studies. 自从遇见了这个好朋友,他已在学习上取得了巨大的进步。 例如:It is twenty years since she joined the Party. 她入党二十年了。(主句中的动词表示的是状态,用现在时。)小试牛刀:it is five years since we last time.(meet) Mr green has taught in that school since he (come) to China three years ago. 7.until 引导的从句:表示一个动作持续到某一时刻。 (1)表示“直到……”,如果主句中的谓语动词是延续性动词时,用肯定或否定形式都可以,但表达的意思不同。(2)表示“直到……才”,主句用否定式,从句用肯定。如果主句中的谓语动词是瞬间动词时,必须用否定形式。

时间状语从句讲解讲课教案

(adverbial clause of time) 概念:在复合句中,由时间连接词引导的状语从句叫做时间状语从句。(在复合句中,要注意主句和从句的时态大多都要保持一致。) 1.由when, while, as,after,before,since,untill,引导的时间状语从句。例如: When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候,你就是在开始知道一些事物了。 When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候,它在生长,它感到压抑,它蓄存着这么一种爆炸性力量,一旦冒出,它就会炸破一切! Strike while the iron is hot. 趁热打铁。 You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候,你就能感觉到空气在流动。 Our headmaster laughed as she spoke.我们的校长边谈边笑。 主要时态:主过从过;主将从现;主句为一般现在时,从句不受影响。 编辑本段when, while和as的区别 when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。并且when 有时表示“就在那时”。例如: When she came in, I stopped eating.她进来时,我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当我住在农村时,我常常为他担水。(延续性的动词) We were about to leave when he came in.我们就要离开,就在那时他进来了。 While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生(或者相对应)。并且while有时还可以表示对比。例如: While my wife was reading the newspaper, I was watching TV. (was reading 是延续性的动词,was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球,而你喜欢打篮球。(对比) As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生;as也可以强调“一先一后。例如: We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”)As we was going out, it began to snow.当我们出门时,开始下雪了。(as 强调句中两个动作紧接着先后发生,而不强调开始下雪的特定时间) 2.由before和after引导的时间状语从句。注意before引导的从句不再用否定式的谓语,并且当before引导的从句位于主句之后,有时译成“就,才”。还要注意主句和从句之间的时间关系。当主句用将来时,从句总是用现在时;如果before 引导的主句谓语用的是过去完成时,则从句动词多用一般过去时,这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和

时间状语从句及练习

时间状语从句常见的从属连词有:(注意其汉语意义) when, while, as, before, after, since, until (till) once as soon as, the moment, the minute, immediately, directly, each/every time, the first time, the last time, next time, by the time, whenever等。例如:Every/Each time I was in trouble, he would come to my help. I thought her nice and honest the first time I met her.注意:(1)when, while, as的区别: 1)when引导从句时,主从句的动作有先有后,也可以同时进行,从句的动作可以是持续性的,也可以是短暂的。如: When I got to the airport, the plane had already taken off. (主先从后)(短暂性) When I lived there, I used to go to the seaside on Sundays. (同时) (持续性) When the movie ended, the people went back. (从先主后) 2)while侧重主从句动作的对比,且从句的动词必须是持续性的。如: While we were chatting she was looking at the time table on the wall. 3)as引导从句时侧重主从句动作同时或几乎同时进行,从句的动作可以是持续性的,也可以是短暂的。如: Sometimes I watch TV as I am having breakfast. 4)when和while还可以是并列连词,意思分别是“就在这时”,“然而”。如: I was having a rest on the sofa when the telephone rang. They were surprised that a child should work out the problem while they couldn’t .注:并列连词when常用与以下句型中:①…was/were doing…when…(正在做…突然)②…was/were about to do…when…(刚要做…突然)③…was/were on the point of doing…when…(刚要做…突然)④…had just done…when….(刚一…就)⑤Hardly/Scarcely had…done…when…(刚一… 就)(2)before引导从句时,词义非常灵活,注意下列句子中的before的词义: 1.Before I could get in a word, the tailor had measured me.(还没来得及…就) 2.We hadn’t run a mile before he felt tired.(还没…就) 3.We had sailed 4 days before we saw land.(…才…) 4.Please write it down before you forget it.(趁还…没就)(3)till (until) 和not…till (until) 1)till (until):主句谓语动词必须是持续性的,意思是“到…为止“如: He remained there till/until she arrived. 2)not…till (until)…: 主句谓语动词必须是短暂性的,意思是“直到…才”如: She won’t go to bed till/until he returns home. 3)not…until还有强调式和倒装式:强调句:It is not until he returns home that she will go to bed.倒装句:Not until he returns home will she go to bed.(4)几个极易混淆的时间状语从句:1)It was +时间点+when…(当的时候时间是) It was 5 am when we arrived at the village. 2)It was/will be+时间段+before…(没过…就/过了…才) It was/will be two weeks before we met/meet again.3)It is /has been +时间段+since…(自从…以来有…) It is/has been 3 years since we last met.突破点:一看be动词的时态,二看时间段还是时间点。注意:在“It is /has been +时间段+since…”句型中,从句的动词必须是短暂性的,如果是延续性的动词,时间要从从句的动作结束时算起。如: It is 3 years since I smoked.( 我戒烟有三年了) 补充:as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner…than…, hardly/scarcely….when….和once这些从属连接词引导的从句都表示 从句的动作一发生,主句的动作随即就发生,常译为“一…就…”。从句中一般时态代替
