状语从句

状语从句的作用:

状语从句的种类:

状语从句的考点:

?各种状语从句的从属连词有哪些;

?同一种状语从句中从属连词的区别;

?同一个从属连词在多种状语从句中的运用。

一、时间状语从句:

引导词:When, whenever, as, while, before, after, until (till), since, as soon as, once

each/every time, next time, the first/…time, the moment, the minute, instantly, immediately, directly(一…就…), no sooner…than, hardly/scarcely…when

考查重点:

1)when的用法:was doing…when, be about to do… when“正在做

某事/正要做….突然发生另一件事”。

2.)几种特殊句型与强调结构的区别:

It is + 时刻+ when…

It is/has been + 段时+ since(谓语动词一般为过去时)…

It will be/was + 段时+ before (现在时/过去时).“过一段时间…才”

3).before的用法:

A:表“还未来得及…就…”B:表“过一段时间才…”,

4).until的用法:在not…until结构中,谓语用短暂性动词,“直到…才”;谓语为延续性动词,用until表“一直持续到…”。

5) no sooner…than,hardly/scarcely…when 刚……就

A. 时态:主句用过去完成时(had + pp)从句用一般过去时

B. 倒装:no sooner/hardly/scarcely放句首,主句要倒装

She had no sooner arrived at the station than the train started to move.

No sooner had she arrived at the station than ….

He had hardly entered the hotel when it began to snow.

Hardly had he entered the hotel when it began to snow

二、原因状语从句:

引导词:because, since, as, for, now( that), considering (that), seeing (that)

考查重点:because, since, as, for

because—直接原因,非推断.语气最强.回答why

since –通常放句首.译为“既然”

as–不谈自明的原因,语气最弱.

for–放句中,对前面一句话的内容的补充说明。

三、地点状语从句:

引导词:where. Wherever。Where指“在某个地方”,wherever指“无论哪里,在任何一个地方”,在使用时:一要注意两者的含义区别。二要注意状语从句和定语从句的区别。三要注意在状语从句中不可使用介词+which引导。出题者既考状语从句又考定语从句和状语从句的区别。还加入名词性从句这一干扰项。四、目的状语从句和结果状语从句

引导词:in case, so that, in order that, for fear that。So that引导状语从句只能置于主句之后。In order that 引导状语从句可放主句之前或之后。目的状语从句的谓语常含有can,could,may,might情态动词。这也是与结果状语从句的一个区别。引导结果状语从句的连词有:so that,so…that,such…that.结果状语放在主句之后。

注意:在so…that,such…that结构中一般成分齐全。这也是与as引导定语从句的区别。在so…as,such…as 这一结构中,as引导定语从句,在句中做成分。

五、条件状语从句:

引导词:if ,as/so long as,as far as,unless,in case(如果)

条件状语从句一般考查三点:

1)在条件状语从句中常用一般现在时表示一般将来时,用一般过去时表过去将来时。

2)if,unless,in case是考查重点。

3)when还可表条件,这一点不可忽视。意思是:既然,考虑到。如:

How can they learn anything when they spend all their spare time,watching television?他们把所有空闲的时间都用来看电视了,还能学到什么东西呢?

六、让步状语从句:

引导词:though /although“尽管”,even if /even ,though“即使”,no matter how(what,when,which,who,where),however(whatever,whenever,whichever,whoever,wherever), as“尽管”

1)although与though可互换,都可以与yet,still连用,但不能和but连用。

2)However引导让步状语从句时后紧跟形容词或副词。

3)While也可引导让步状语从句,这一点特容易被考生忽视。

4)Whatever修饰名词,“无论什么”,however修饰形容词、副词,“无论多么,无论怎么”。

5)even if/even though(即使)与as if/as though(好像)这两组学生容易混淆,也是出题者关注的对象,平时要记准含义。

七、比较状语从句和方式状语从句:

引导词:than / as—注意省略

as/like,as if/as though

The project was completed earlier than (it was) expected.

He worked as fast as a skilled worker (worked).

Repeat this as often as (it) is necessary.

Then see a doctor as soon as (it is) possible.

Do you have to feed plants like you feed chickens?

Do it like I tell you.

知识拓展:注意状语从句的省略。

状语从句讲解和练习

英语语法从句讲解

从句 从句按其在主句中的句法功能可分为三类: 即名词性从句、形容词性从句(即定语从句)和副词性从句(即状语从句)。 引导从句的词称作关联句. 一、名词性从句 引导这些名词性从句的关联词包括: 从属连词that, if, whether; 连接代词 who,whoever,whom,whomever,which,whichever,what,whatever,wh ose; 连接副词where, when, why, how。 其中, 从属连词只起连接作用, 在从句中不充当任何句法成分, 而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分. That Owen should have married his cousin is not at all surprising. The fact is that he didn't go to the dinner party. I don't know if he will attend the meeting. Have you heard the news that Mary is going to marry Tom? 你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句) [提示]

1. 在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末. It's well-known that water is indispensable to life.(形式主语) 2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。 He made it quite clear that he preferred to live here. 3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语 从句。whether可与or(not)连用, 而if不可以。 I don't know whether (if) she is at home. Whether she comes or not makes no difference. 4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。 He always means what he says. She suggested (that) he do it at once. 5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。 We are familiar with the idea that all matter consists of atoms. The news that we are invited to the conference is very encouraging.

状语从句讲解及习题附答案

(一)状语从句概述 定义状语从句用作状语,是起副词作用的句子。 位置状语从句可以放在主句之前,也可以放在主句之后,时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。 分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。 作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。 (二)状语从句详解 1. 时间状语从句 引导词用法示例 when 意为“当…的时候”。When 引导从句的谓语动词可以 是延续性动词,也可以是 瞬间动词。并且when有 时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。When he arrives, I’ll call you. When you laugh and smile, your body relaxes. while 意为“在…的时候,在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.

的,发生时间较长,并强调主句和从句的动作同时发生(或者相对应)。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的, 发生时间较短,一般用于 主句和从句动作同时发 生;as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语, 并且当before引导的从句 位于主句之后,有时译成 “就,才”。当主句用将来时,You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada

高中英语语法---条件状语从句讲解

条件状语从句 概念定义 由引导词if或unless引导的状语从句叫做条件状语从句。在英文中,条件是指某一件事情实现之后(状语从句中的动作),其它事情(主句中的动作)才能发生,通常译作“假如”。(注意:在含有条件状语从句的复合句中,表示将来时态,主句是一般将来时态,祈使句或情态动词,从句要用现在时态,[主将从现原则](主将从现,将并非指将来时,还指表示将来含义的,跟着if后的那句话是从句。) 类型 条件状语从句 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如: 1) If you ask him,he will help you. 如果你请他帮忙,他会帮你的。 2) If you fail in the exam,you will let him down. 如果你考试不及格,你会让他失望的 if引导的条件状语从句既可以将从句放前面也可以将从句放后面 (如果天下雨,我们就不玩了)If it rains,we will stop playing.‘ 转为We will stop playing if it rains. if引导的条件状语从句

另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如:If I were you,I would invite him to the party.如果我是你,我会邀请他参加聚会。I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车,我会到的早一点儿。 那么,除了if之外,是否还有其他连词也可以引导条件状语从句呢?回答是肯定的,不仅有,还有很多。这些词由于出现的频率较小,且用法较复杂一些,所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非,若不,除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身,你就不能及时赶到那儿。 Unless it rains,the game will be played.除非下雨,比赛将照常进行。 2、on condition(that)...在……条件下,如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相,条件是你答应保密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果,假如 supposing引导的条件从句表示一种假设条件。 Supposing it rains,shall we continue the sports meeting?倘若下雨,我们的运动会还要继续举行吗? Supposing anything should go wrong,what would you do then?假如出了什么问题,你准备怎么对付?

When (While) we were at school, we went to the library every day. While表示时间段,因此,while 从句的谓语动词要用延续性动词。如: Please don't talk so loud while others are working. As与when用法相似,但着重强调主句动作与从句动作同时发生,有"随着……"或"一边……一边……"之意。如: As you get older, you get more knowledge.随着年龄的增长,你获得的知识就越多。 2.Because,as,since 的区别: Because用于表示直接原因,回答why提出的问题,语气最强;As用于说明原因, 着重点在主句,常译成"由于";since表示显然的或已知的理由或事实,常译成"既然"。如: Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.
