状语从句讲义(讲稿)

状语从句讲义(讲稿)

状语从句状语从句在高考试题中由于其他从句的干扰,以及倒装句,强调句的介入,使得状语从句更为复杂。

状语从句是一种副词性从句,通常由一个从属连词或一个起连词作用的词组引导。

状语从句1. 时间状语从句常见的连词(组):when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。

可以引导时间状语从句的副(介)词(短语)或名词短语:directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。

注意点如下:(1) when, while, as引导的时间状语从句as表示“当……的时候”,往往和when/ while通用,但它着重强调主句与从句的动作或事情同时或几乎同时发生。

when(at or during the time)既可以表示在某一点的时候,又可以表示在某一段时间内,主句与从句的动作或事情可以同时发生也可以先后发生。

while强调一段时间,仅表示从句和主句的动作同时发生,并且有延续意义,该从句中的动词一般要用延续性动词,从句中常用过去进行时态或一般过去时态;当when表示a period of time时,两者可以互换。

She came up as I was cooking.(同时) 在我做饭时,她走了过来。

When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时,每天都去图书馆。

While they were watching TV, I was preparing myself for the coming examination.他们在看电视,而我在为即将到来的考试做准备。

状语从句一、基本概念:在复合句中修饰动词、形容词或副词的从句叫状语从句。

状语从句在句中的作用相当于一个副词,因此也叫副词性从句。

从句的位置可放在句首,也可在句末。

放在句首时,从句后面常用一个逗号;放在句子末尾时,从句前一般不用逗号。

二、状语从句分类: 根据它们的含义可分为:时间、地点、原因、目的、结果、方式、让步、条件、比较等9种。

三、状语从句重点: 掌握并正确使用好不同种类应使用的相应的连词。

一)时间状语从句1.连词有:when, as, while, after, before, as soon as, since, till (until) , once, whenever, no sooner… then, hardly… when, scarcely … when, the moment, every time, immediately, the instant, directly, etc.e.g. I was going over my lessons when my mother came in .Don’t speak while you are eating.We discussed his suggestion as we went along (前进).2.注:由as soon as,the moment, immediately, directly, instantly, once,no sooner…than ,hardly/scarcely…when等引导的状语从句,这些词都可译为“一…就”之意e.g.Please come to my office as soon as the class is over.Hardly/Scarcely had I got to the office when the manager left.No sooner had he entered the room than the phone rang.3. When的用法:1)表时间,“当…时候”可引导“点时间”,也可以引导“段时间”The fire was put out when they came.I hope you’ll think of my words when you drive on the busy roads.2)“如果…,要是…”Turn off the switch when anything goes wrong with the machine.3)“既然…”Why do you want a new job when you’ve got such a good one already?4)“虽然,然而,可是”He walks when he might ride.We have only three chairs when we need five.5)并列连词“…这时候…”I was about to go to bed when the phone rang a second time.4.while的用法:1)表时间,“当…时候”可引导“段时间”Please be quiet while I am talking to you.2)“虽然,尽管”While I understand what you say, I can’t agree with you.3)表示对比,“而,然而”He is strong while his brother is weak.5. 表示两个同时发展变化的事件, 状态,用as,常翻译成“随着”As he gets older, he gets more wise.As time went on, her hair turned gray.6. Until, till两词可替换,但until语气比较强,可置于句首,可用于强调句。

Wait till/until he comes. Don’t leave until he comes.Not until he comes can you leave. It isn’t until he comes that you can leave.7. Since (自从)的用法1). since表示自某一时间点以来,常与完成(进行)时态连用。

主句一般用持续性动词,如用非持续性动词时必须强调动作的频度或多次、多个。

I have lived in Cixi since I graduated from ECNU.自从华师大毕业后,我一直住在慈溪。

I have returned to Shanghai twice since I graduated from ECNU.自从华师大毕业后,我回过两次上海。

2). Since 引导的从句中,如是持续性动词,往往理解为某一状态的终止。

He has telephoned me frequently since he was ill.他病好后经常给我打电话。

It has been a year since I worked here.我不在这里工作已经一年了。

3).It is/has been +一段时间+since…It is/has been a long time since he was ill.(持续性动词)他病好了很长时间了。

It is/has been a long time since we parted.(非持续性动词)我们分开很长时间了。

8. Before(在…之前), before引导的时间状语从句如果是过去时,其修饰的主句可用一般过去时或过去完成时。

I must finish this letter before I go home.All the birds flew away before I started to fire.Mr. Brown had worked in a bank for a year before he came here.注意before的重点用法:1)It was +时间段+before+S+V 过了多久某人就干某事了It was five hours before I finished the work.过了五个小时,我就完成那项工作了。

2)It wasn’t +时间段+before+S+V 没过多久某人就干某事了It wasn’t ten minutes before he saw the manager.没过十分钟他就见到经理了。

3)It will be +时间段+before+S+V 过多久才发生某事It will be five hours before I finish the work.我要过十分钟才能完成这项工作。

4)It won’t be +时间段+before+S+V 过不长多少时间就会发生某事It won’t be five hours before I finish the work.用不了5个小时我就能完成这项工作。

9. by the time的用法。

指到某一点时间为止,主句常用完成时态。

若主句是be的系表结构或像know等表示“认知”的持续动词,则往往用一般现在时。

By the time he gets there, his father has already gone.By the time he went to abroad, he was fourteen.二)地点状语从句连词有:where , wherever, anywhere, everywhere, nowhere.e.g. You had better put the book back where you took it .Where there is a will,there is a way.Wherever you go, I go too.You can go anywhere you like.注意区别where引导的定语从句.Just stay where you are and don’t move.(状语从句)Just stay in the place where you are and don’t move.(定语从句)三)原因状语从句连词有:because, since, as, now that , not that…but that,forthe reason that, in that等。

1. 在这几个引导词中,because语气较强,常用来表示直接原因,可回答why提出的问题,as语气较弱,常译为“由于”,since和now that语气最弱,常译为“既然”,as,since和now that都不能用来回答why提出的问题。

e.g.He did not come to school today because he was ill.Since you are here ,you had better stay.Now that you are all here,let’s begin the meeting.The woman felt a bit worried,not that she had been out too long ,but that her children were waiting for her at home.2. for 引导一个句子表示原因时在语法上不属于原因状语从句,而属于并列句,for在句中是并列连词,表示对前句内容进行补充说明。

e.g.You had better put on your coat,for it is rather cold outside.3. 原因状语从句不能与表示结果的并列连词so连用。

如so 不可与because, as, since等表示原因从属连词一起使用。

As the weather was fine, we decided to climb the mountain.如不能说:As it was hot, so he turned on he electric fan.而应该说:As it was hot ,he turned on the electric fan . 或者:It was hot ,so he turned on the electric fan.四) 条件状语从句连词有:if, unless(= if not )so (as)long as, supposed/supposing(假如,假设)/provided/ providing(如果)+(that),on condition that(如果), in case (万一),once (既然)等。
