状语从句

什么是状语:

句子中修饰动词、形容词等的句子成分叫状语,用来从地点、时间、原因、目的、结果、条件、让步、比较、方式和伴随状况等方面修饰说明谓语。

e.g. He speaks English very well.(副词作状语)

e.g. He is playing under the tree.(介词短语作状语)

e.g. I come specially to see you.(不定式作状语)

e.g. If I am not busy tomorrow,I will play football with you.(从句作状语)

e.g. Having had a quarrel with his wife,he left home in a bad temper.(分词作状语)状语从句:

状语从句就是在复合句里起状语作用的从句,可以表示时间、地点、原因、目的、结果、让步、比较、方式、条件等。引导状语从句的连词叫做从属连词。状语从句的位置可以在句首,也可以在句末。放在句首时,从句后面常用逗号与主句隔开;放在句末时,从句前面往往不用逗号。

If it’s fine tomorrow, I will go with you.

I will go with you if it’s fine tomorrow.

状语从句分类:1、时间状语从句

2、地点状语从句

1/ 10

3、原因状语从句

4、目的状语从句

5、结果状语从句

6、条件状语从句

7、让步状语从句

8、比较状语从句

9、方式状语从句

时间状语从句

从属连词:when, while, as, before, after, till/until, since, whenever, as soon as (一……就)……

时态:主将从现,主情从现,主祈从现

一、When/while/as(当…时候)

区别:主句动作与从句动作发生的时间(同时/之前/之后);从句动词(延续性/瞬时性)

1)When:

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瞬间性动词,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。且when引导的时间状语从句中一般用一般现在时表将来(主将从现)。

2/ 10

e.g. I will call you when I get there.

e.g. When I came home my wife was cooking dinner.

e.g. I will go home when the rain stops.

e.g. When I got to the airport,the guests had left.

A)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;

e.g. When (you are) in trouble, ask her for help.

B)当when引导的时间状语从句的主语与主句主语相同时,往往还可以省略从句的主语并用“when+分词”的形式替代该状语从句。

e.g. When I came into the room (=When coming into the room), I found him lying there asleep.

2)While

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,或者强调主句的动作发生在从句动作的进行过程中,此时主句中的谓语动词通常是非延续性动词。记住,从句中始终是延续性动词,且从句多用进行时态。(while还可以表示对比,译成“然而”,放在句首可以表示“虽然”)

e.g. I met her while I was at school.

e.g. While I was sleeping, the UFO arrived.

3/ 10

e.g. We were doing our homework while it was raining outside.

e.g. Study while you study; play while you play.

3)As

as引导时间状语从句时表示①“当……时”(只引导瞬间性动词,两个动作是紧密联系的,一前一后进行),②“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),③“随着”,一种动作随着另一种动作的变化而变化从句中只能接延续动词。

e.g. He jumps as he goes along.

e.g. As the wind rose the noise increased.

【When, while , as 辨析】

三者均可以表示“当……时候”,如果主句表示的是短暂性动作,而从句表示的是延续性动作(主短从延),三者可以通用。

I met Mr Li as / when / while I was walking along the street.

(1)While意为“在……期间”,从句的谓语必须是延续性动词。

The plane had left when we got to the airport.

(2)表示带有规律性的“每当”,或者主从句动作有先后时,都只能用when.

When winter comes, it becomes cold.

(3)表示“随着”时间的推移,主从句的内容是两种变化的情况,只能用as.

4/ 10

As the day went on, the weather got worse.

(4)强调主句动作延续到从句所指的整个时间,只能用while.

二、Before/after

5/ 10

before引导时间状语从句时表示主句的动作发生在从句动作之前,常翻译为在“……之前”,“……才……”或“……就……”。

e.g. See me before you leave.

e.g. Before they drive any of the buses, they will have to pass a special test.

after引导时间状语从句时表示主句的动作发生在从句动作之后

e.g. I saw them after I arrived.

e.g. I found his pen after he has left.

A. when

B. before

C. since

D. that

It was some time ____ we realized the truth.

A.when

B. until

C. since

D. before

三、Till/until/not……until

1、肯定句:till和until这两个词作连词和介词时的意义和用法相同,一般可以换用(放在句首时通常用until的形式,till在口语中更为常见)。主句的谓语动词必须是持续性的,表示“到……为止”,“直到……才(开始)”。

6/ 10

e.g. Walk till you come to a white house.

e.g. We didn’t discuss the problem until he came back.

2、否定句:Not ……until,主句的谓语动词则为短暂性的,表示“直到……才”,若主句谓语动词为延续性动词,根据上下文可表示“没有到……”

He didn’t wait until/ till I returned.他没有等到我回来。

not until的三种用法:

1)用在句中的基本用法

e.g. He did not appear until the concert ended.

2)与that搭配的强调结构

e.g. It was not until the concert ended that he appeared.

3)用于句首的倒装结构主句倒装

e.g. Not until the concert ended did he appeared.

7/ 10

3)I don’t really work here; I ____ until the new secretary arrives.

A. just help out

B. have just helped out

C. am just helping out

D. will just help out

四、Since

Since引导的时间状语从句表示“自从……以来”,需注意以下两

1)引导时间状语从句时,一般指的是“从过去的某一时间点以来”的概念,表示动作从过去一直持续到现在。从句用一般过去时,主句用完成时。

e.g. I have never seen him again since he left here.

e.g. They have been friends ever since they were in school.

2)若表示到过去某一时间前的情况,则主句用过去时,从句用过去完成时。

通搭配为it was+时间段+since 过去完成时或it is+时间段+since过去时

e.g. It is two years since I became a postgraduate student.

e.g. It was three years since we had been there.

3)延续性动词相反翻译,瞬间性动词正常翻译

It is three years since I smoked a cigar. 我不抽烟三年了。

It is three years since I left there. 我离开那里已经三年了。

【巩固练习】

C. when

D. since

五、“一……就……”as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner ……than……,hardly/ scarcely……when……和once

1)as soon as

①表示对将来事情进行推测(用一般现在时表示将来)

②对过去事情进行陈述,表示两个动作同时进行或一前一后

2)no sooner……than……和hardly……when……

因为没有表达一种条件性,只能对过去事情进行陈述

①时态方面:主句用过去完成时,从句用一般过去时

②倒装同时满足三点:否定词提前、主倒从不倒、部分倒装(be、助、情提到主语之前)。

I had hardly got home when it began to rain.

9/ 10

Hardly had I got home when it began to rain.我一到家天就下起雨来。

时间状语从句讲解和练习

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.

(完整word版)高中英语状语从句用法详细解析

高中英语状语从句用法详细解析 一、定义: 在句中作状语的从句是状语从句,修饰主句中的动词、形容词或副词等。状语从句由从属连词引导,从属连词在句中不充当句子成分,只起连接作用,状语从句放在句首时,要用逗号,放在句尾时不用。 二、分类 根据意义上的不同,状语从句可分为:①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句 三、时间状语从句 (一)引导时间状语从句的连词有:as, when(whenever), before, after, as soon as, until(till), since, every time, once. (二)、“as” as, when, while都有“当……的时候”,可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词,常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问,连接并列分句。When表示“就在……的时候”, while意反而,可是,表示转折。

时间状语从句讲解与练习

时间状语从句讲解与练习

when, while 和as 引导时间状语从句的用法 一、when 的用法 如果只从现象来看,when 从句用的最多的是一般过去时,而主句的时态没有限制,根据具体情况而定。 1. When he was a child he was always trying out new ideas. 他小时候就常常试验一些新的设想。 2. When she came into my room, I was just reading a book. 她走进我房间时,我正在看书。 3. Were you writing when the teacher came in? 老师进来的时候,你在写信吗? 4. Sorry, I was out when you called me. 对不起,你打电话来的时候我出去了。 5. He was on the point of leaving when someone knocked at the door. 他正要走,这时有人敲门。 6. I thought of it just when you opened your mouth. 就在你要说话的时候,我也想到了。 7. I had hardly[scarcely] closed my eyes when someone knocked at the door. 我刚一闭上眼,就有人在敲门了。

根据以上的例句,我们可以总结出一点:when 从句的A事件,相当于另一个事件B发生的时间点。也就是说,when 从句的重点不在动作本身发生的状态,而只是把它作为一个时间点,所以when 多数情况下用的是一般过去时,则不用正在进行时。因为如果用正在进行时,它表示的就是一段时间而不是一个时间点了。根据这一点,有的文章补充说:when 从句的动词大多是瞬时动词。 实际上,when 从句也可以有其它的时态,但几乎也不用进行时,因为它也只是作为一个时间参照点。 1. When I got to the airport, the guests had left. 当我赶到飞机场时,客人们已经离开了。 2. When he had finished his homework, he took a short rest. 当他完成作业后,他休息了一会儿。 3. Why do you want a new job when you have got such a good one already? 你已经找到如此好的工作,为何还想再找新的? 4. You shall borrow the book when I have

高中英语状语从句讲解

高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如: 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .(原因状语从句) 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类,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和特殊的连接词即考点。现分别列举如下: 1.时间状语从句 常用引导词:when, as, while, as soon as, while, before, after, since , till, until 特殊引导词:the minute, the moment, the second, the instant, immediately , directly, every time, the day,no sooner …than, hardly …when, scarcely …when (1)Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 (2)The children ran away from the orchard(果园) the moment they saw the guard. The moment he saw me, he ran away. 他一看见我,就跑了。 He said he’d call you the moment he got home. 他说他一到家就给你打电话 (3)The instant I saw him, I knew he was the man from the restaurant. (4)Immediately you begin to speak, he gives you his full attention.你只要一开始说话,他就全神贯注地听。 (5)My sister came directly she got my message. 我妹妹一收到我的信息就来了。 (6)Every time I listen to your advice, I get into trouble. (7)no sooner... than... ,"一...就..." ,引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. (8)He had hardly sat down when the telephone rang.他刚坐下电话就响了。 He had scarcely sat down when there was a knock at the door. 他刚坐下就有人敲门 另外,如果把hardly放于句首,主句要用倒装结构。如: Hardly had I finished eating when he came in. 我刚吃完他就进来了。 2.地点状语从句 常用引导词:where 特殊引导词:wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories.

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. Until you told me, I had heard nothing of what happened. 直到你告诉我以前,出了什么事我一点也不知道。否定形式有另外两种表达方式: (1)Not until …在句首,主句用倒装。 Man did not know what heat was until the early years of the 19th century. =Not until the early years of the 19th century did man know what heat was. (2)It is not until…that… He will not go to bed until his mother comes home. =It is not until his mother comes home that he will go to bed. 4. as soon as/the moment/the instant/the second/the minute/immediately和hardly/scarcely…when, no sooner…than a. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和从句的动作同时发生。译为“一……就” Eg:As soon as she heard the news, she began crying. b. hardly/scarcely…when, no sooner…than都可以表示"一……就……"的意思,但主句谓语动词一般要用过去完成时,从句谓语动词要用一般过去时。 Eg:I had hardly / scarcely got home when it began to rain. I had no sooner got home than it began to rain.注意:如果hardly, scarcely 或no sooner置于句首,句子必须用倒装结构:Hardly / Scarcely had I got home when it began to rain.
