时间状语从句

用句子表达一件事情或一个行生的，个句子就叫状从句。状从句根据其所表示的

不同，所使用的也不同。下面我一起来看一下几个常的状从句：

1． when 引的从句：表示主句的作和从句的作同生，或从句的作生在主句作之前。

例如： I was going out when a visitor came. (作同生。) 我正要出，有客人来。

I shall tell her the good news when she comes.她来，我将告她个好消息。

小牛刀： I found mother cooking for me. I got home.(when)_______________________________________ He was listening to the radio when I home. (get)

2． while引的从句：表示“当??程中”，某一段内主句和从句中所表示的作在同

一期生。由于while从句表示一个持的行，所以从句中要用持性，并且持性常用行

。

例如： Keep an eye on my little sister while I am away.我不在，照看一下我的小妹妹。

While we were watching TV, Jim came in.我看的候，Jim 来了。

小牛刀：It started to rain.We were playing football.(while)_______________________________________

Lucy was cleaning the room Lily was listening to music.

3． as引的状从句：表示“当??的候；一??一??；随着??”，其从句的主与主句的

主往往是同一人或物。

例如： She sang as she worked.她一工作一唱歌。=She was singing as she was working.

I saw him as he was getting off the bus.正当他下公共汽,我看了他。

小牛刀：we walked, we talked.

You will grow wiser you grow older.

4． before引的从句：一般表示主句的作生在从句作之前。

例如： I didn ’t know any English before I came here.我到儿来之前，一点英都不懂。

例如： I had written my report before my father came back.

小牛刀： He bought the ticket he went to see the film.

5． after引的从句：表示主句的作生在从句作之后。

例如： After he locked the door, he left.他上后，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

了一棋。

小牛刀： 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引的从句：表示“自从??以来”，从句中的一般表示作的起点，用去。主句中的

表示作延的情况，一般用在完成。如果主句中的表示的不是延的作而是表示目前的状，可用一般在。

例如： Since he met this good friend, he has made great progress in his studies.

自从遇了个好朋友，他已在学上取得了巨大的步。

例如： It is twenty years since she joined the Party.她入党二十年了。（主句中的表示的是状，

用在。）

小牛刀： 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引的从句：表示一个作持到某一刻。

（ 1）表示“直到??”，如果主句中的是延性，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。如果主句中的是瞬，必用否定形式。

例如： They worked until it was late.他一直工作到天黑。

She didn ’t go to bed until she finished her homework.她写完作才睡。

小牛刀： All the people left. He waited.(until)________________________________________

He went to bed . his father came

8． as soon as引的从句表示“一??就”，作密相。

例如： As soon as she came to the classroom, she began to read English.她一到教室，就开始英。

小牛刀： We start to sing. It''s12 o''clock.(as soon as)________________________________________

9. by the time到。。。止(所在句子的主句用完成

例如： By the time he gets there , his father has already gone.小牛刀： By the time I got to school, the class.上了。)

他到家的候，他爸爸已走了。

（ begin ）我到校，已开始

知展

1.it is + 段 +since+ 一般去（从。。。以来多了）

例如：it is five years since we met last time.从我上次面已五年了。

2. it is/ will be +段+before+一般在，it was+段+before+一般去

例如： it is a long time before I go to sleep .了很我才睡着。

it was an hour before the police arrived.了一个小，警察才来。

小牛刀： It_____(be) ten years since we ________(leave) that city .

It is reported that it may be two or three months_____it is possible to test on animals

例句

When you arrive in London, please give us a call.

When he was having his lunch, he heard the door bell ring.

As time went on, he grew more and more impatient.

While she was reading a novel, her mother was cooking the

dinner.

Some people waste food while other haven’ t enough.

— I ’ m going to the post office.

— While you ’re there, can you get me some stamps

4、巧 10 个瞬性

在学以when和 while引的状从句，用到了瞬和延。常的瞬有

die( 死 ) ， come(来 ) ，go( 去 ) ，eave( 离开 ) ，arrive( 到达 ) ， begin( 开始 ) ，buy( ) ，,join( 加入 ) ，borrow(，借出 ) ，return( ) 等。

借

这 10 个瞬间动词可用两句口诀来帮助记忆:开始离去,借来还,出生入死,买到家。

注释 :

1." 开始离去 , 借来还 " 为 begin,leave,go,borrow,come,return六词；

2." 出生入死 , 买到家 " 为 join,die,buy,arrive四词。

3. 各词改为相应的延续动词为：

begin → be on, leave → be away from, borrow → keep, go → be, come →be here, return → be back, join →be in, die → be dead, buy → have, arrive →be here 等。 '

5、状语从句与主句的时态问题

1. 由 when、 while引导的时间状语从句的时态：（主过从过）

主句（过去进行时）+when +从句（一般过去）

主句（一般过去时）+when +从句（过去进行时）

主句（一般过去时）+while +从句（过去进行时）

主句（过去进行时）+while +从句（过去进行时）

注意：看动词为短暂性动词用一般过去时，动词为延续性动词则用过去进行时。

小试牛刀： Mother Last

Sunday I When

the students While

Han Meimei

（ cook） supper when I(get) home yesterday. (meet) Lin Hong when I(walk) in the street.

(have ) a meeting, the teacher(come) in.

(sweep) the floor, Lucy(carry) water.

2.由when、after、before、by the time引导的时间状语从句的时态：

主句、从句的谓语动词都已完成，则先发生的动作用过去完成时，后发生的动作用一般过去时。

例如： After he had finished his work, he played a game of chess with his friend.

小试牛刀： When they(get) to the cinema last light, the film(start).

I(go) out with my friends after I(finish) all the homework last

night.

3.时间状语从句与主句的时态不一致。（主将从现：主句用将来时，而时间状语从句用一般现在时）小试牛刀： As soon as I reach Canada, I you up. (ring)

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。

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.

(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.

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.

高考状语从句讲解

状语从句 一、时间状语从句 1、when, while, as 和whenever when 表时间点，时间段 while 表时间段；有“而”的意思 as “当……”,“一边……一边”，“随着……” whenever 每当，无论什么时候 It is cold when it snows. While there is life, there is hope. While we were speaking, he was reading newspaper. Just as Mrs Richards was entering the dinning-room, there was a knock on the front door. As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长，我们用力量换来了机敏，以速度换来了严谨，以热情换来了理智。 注：1)when还可作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式： sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when，while 与as可互换使用。如： When/While/As I was walking down the street，I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句：主句的谓语是延续性动词，主从句均为肯定式，意为“某动作一直持续到某时间点才停止”

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

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：

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.
