时间状语从句讲解

（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

从句的动作的时间关系正好与before引导的从句相反。例如：

It will be four days before they come back. 他们要过四天才能回来。

Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒

才看到我。

My father had left for Canada just before the letter arrived.我父亲恰

好在信到之前去加拿大了。

They had not been married four months before they were divorced. 他们

结婚还不到四个月就离婚了。

After you think it over, please let me know what you decide.你仔细考虑

过以后，告诉我你是怎样决定的。

After we had finished the work, we went home.完成工作之后，我们回家了。（从句用过去完成时，主句用一般过去时）

3.由till或until引导的时间状语从句。till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时

动词时，必须用否定形式；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。till不可以用在句首，而until可以放在句首。例如：

I didn't go to bed until（till） my father came back.直到我父亲回来我

才上床睡觉。

It was not until the meeting was over that he began to teach me En glis h.直到散会之后他才开始教我英语。

I worked until he came back.我工作到他回来为止。

I didn't work until he came back.他回来我这才开始工作。

Please wait until I arrived.在我到达之前请等我。

4.由since引导的时间状语从句。 since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。一般情况下，从句谓语动词用一般过去时，而主句的谓

语动词用现在完成时。但在It is ＋时间＋since从句的句型中，主句多用一般现在时。例如：

I have been in Beijing since you left. 自从你离开以来，我一直在北京了。Where have you been since I last saw you? 自上次我和你见面以后，你到哪里去了？

It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。

It is five months since our boss was in Beijing.我们老板离开北京有五个月了。

5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。这些连词都表示“一……就”。例如：

I will go there directly I have finished my breakfast. 吃完早饭，我立

即到那里去。

The moment I heard the news, I hastened to the spot.我一听到消息，马上赶到了出事地点。

As soon as I reach Canada, I will ring you up. 我一到加拿大，就给你来电话。

编辑本段注意

hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意。主句用过去完成时，从句用一般过去时。当hardly, scarcely, rarely和no sooner位于句首时，

主句应用倒装语序。例如：

He had no sooner arrived home than he was asked to start on another journey. 他刚到家，就被邀请开始另一旅程。

No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太阳刚从地平线上升起，他就起床劳动去了。

Hardly had I sat down when he stepped in.我刚坐下，他就进来了。

He had hardly fallen asleep when he felt a soft touch on his shoulder.这个阿拉伯人刚要入睡就感到肩膀上被轻轻一触。

6.由by the time引导的时间状语从句。注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时；如果从句的谓语动词用一般现在时，主句的谓语动词用将来完成时。例如：

By the time you came back, I had finished this book.到你回来时，我已经写完这本书了。

By the time you come here tomorrow, I will have finished this work. 你明天来这儿的时候，我将已经完成此工作了。

7.由each time, every time和whenever引导的时间状语从句。例如：

Each time he came to Harbin, he would call on me. 他每次来哈尔滨，总是来看我

Whenever that man says“To tell the truth”, I suspect that he's about to tell a lie.每当那个人说“说实在话”的时候，我猜想他就要说谎了。

You grow younger every time I see you. 每次遇到你，见你更年轻了。

8.由as long as和so long as引导的时间状语从句。这两个连词表示“只要“例如：

You can go where you like as long as you get back before dark. 你可以随意到哪里去，只要在天黑以前回来就行。

I will fight against these conditions as long as there is a breath in my body! 只要我一息尚存，我就要反对这种境况。

这是一般现在，一般过去，现在进行，过去进行，现在完成，过去完成，现在完成进行，一般将来，过去将来时的时间状语:

1.Often,usually----------动词原型do,does,am,is, are

2.yesterday,last Sunday,in the past-------动词过去式did,was,were

3.now--------be+doing

4.while,at that time,-------was doing,were doing

5.since从句,for 2 days,------have done,have been

+过去的某个时间点----had done,had been

7.与现在完成相似-------have been+持续动词ing形式

8.一切表示将来的时间状语，in+一段时间-------将来要发生的一般性动作,

will,shall+原型

9.与一般将来时相似-----------would+原型

1时间状语从句

时间状语从句常用从属连词when, after, until, as soon as, 等来引导。

当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。

如：Please call me when you get there. 当你到那时，请给我打个电话。

I will write to you as soon as I arrive in Beijing. 我一到北京就给你写信。

<温馨提示> since 引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时；而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为：

It has been/ is + 一段时间+ since + 过去时。

如：I has been/ is three years since we met last time. 自从我们上次见面，已经三年了。

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.

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. She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句

He knocked at the door , when my mother was sleeping. 2.由while引导的时间状语从句“与…同时，在…期间”，谓语动词必须是延续性动词。EG：Lucy was cleaning the room while Lily was listening to music. 3. 由before/after 引导的时间状语从句，before“在…之前”，after“在…之后” Eg：He went to the office before he visited Mr. Zhong.

状语从句 在复合句中作状语，位置灵活。 状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。 （一）时间状语从句 1.when, as, while a.when表时间，从句既可以用延续性动词，又可以用瞬间动词。 Eg: When I get there I will call you. 如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be 可省。 Eg：When （you are）in trouble, you can ask her for help. 如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。Eg：When I came into the room(When coming into the room), I found the light was off. b.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。主句的谓语动词 通常是非延续性动词。 Eg: He came in while I was reading a book. 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. No sooner had I got home than it began to rain。 1. We called the First - Aid Center_______ the traffic accident happened. A. immediately B. shortly C.quickly D. hurriedly 2.

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.

初中时间状语从句语法及练习

英语时间状语从句讲解 （一）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. 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。 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。这种说法也可以参照。 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。例如： 2. When he had finished his homework, he took a short rest. 3. Why do you want a new job when you have got such a good one already? 二、while 的用法 相比于when 来说，while 从句的侧重点就不一样了。while 从句的侧重点在于描述动作正在发生的状态，它的意思是：当while 事件正在发生的时候，另一件事如何如何。所以，while 从句一般用的是正在进行时。而另一件事的状态没有硬性的要求，根据具体情况而定。例如： 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin Tao came to see him. 3. While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。 从时间的角度来看，while 表示的是一段时间，是一个过程。这是while 的侧重点。因此，如果含有“一段时间”的含义的时候，就可以用while。 6. Strike while the iron is hot. 趁热打铁。 这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。 再例： —I'm going to the post office. —While you're there, can you get me some stamps? 三、as 的用法 as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。但与while 从句不同的是，as 从句用的一般不用正在进行时，而只是一般过去时。as 从句一般可以翻译成“边……边……”。例如： 1. As my mother sang those old songs, tears ran down her cheeks. 2. The students took notes as they listened. 学生们边听课边做笔记。 3. As we talked on, he got more and more excited. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，不像while 从句有强调while 动作本身的意思。因此，as 常常翻译成“随着……”之意。 例如： 1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。
