英语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
这三个词的意思很简单，都有“当……时候”的意思。但学生经常会问三个词的区别在哪儿，特别是在做选择题的时候。别说是学生，就我个人而言，做这样的选择题要保证百分之百的正确也是不可能的。现根据大量的实例和个人的思考，做一点小结，供大家参考。
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。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：
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 finished reading it.
在我读完这本书后，你可以借阅。
5. When the manager comes here for a visit next week, I’ll talk with him about this.
下周，经理来这参观时，我会和他谈谈此事。
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.
当妻子正在看报纸的时候，我正在看电视。
2. While Jim was mending his bike, Lin Tao came to see him.
正当吉姆修自行车时，林涛来看他。
3. While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。
4. You can’t do your homework while you’re watching TV.
你不能一边看电视一边做家庭作业。
5. While John was sitting biting his nails, I was working out a plan to get us home.
约翰坐在那里咬指甲时，我正在制定一个回家的计划。
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.
当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。
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. 我们继续往下谈的时候，他越来越兴奋。
4. The little girls sang as they went. 小姑娘们一边走，一边唱。
5. Just as he caught the ball, there was a tearing sound.
当他抓住球的时候，有一种撕裂的声音。
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。
2. The atmosphere gets thinner and thinner as the height increases.
随着高度的增加，大气越来越稀薄。
3. As years go by，China is getting stronger and richer.
随着时间一年一年过去，中国变得越来越富强了。
少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。这只能算是特例了。
1. The sad mother sat on the roadside, shouting as she was crying.
伤心的妈妈坐在路边，边哭边叫喊。
2. As we were going out, it began to snow. 正当我们出门时，雪开始下起来。
3. He came in as I was going to bed. 我正要上床睡觉，他进来了。
四、when, while, as 的互换
如果从句动作和主句动作同时发生，并且从句动作为延续性动词时，when，while，as 可以互换使用。这种情况下，它们的细微区别恐怕连英、美人自己也说不清了。
1. When /While /As we were dancing, a stranger came in.
当我们跳舞时，一位陌生人走了进来。[dance 为延续性动词]
2. When /While /As she was making a phone call, I was writing a letter.
当她在打电话时，我正在写信。[make为延续性动词]
3. While/When/ As I was walking down the street, I noticed a police car in front of the
bank.
我顺着马路往前走时，发现银行门前停着一辆警车。
五、比较while, when, as
1）as, when 引导短暂性动作的动词。
例如：Just as / Just when / When I stopped my car, a man came up to me.
我刹车后，有一个人向我走来。
2）当从句的动作发生于主句动作之前，只能用when 引导这个从句，不可用as 或while。
例如：When you have finished your work, you may have a rest.
干完活后，你可以休息一下。
3）从句表示“随时间推移”连词能用as，不用when 或while。
例如：As the day went on, the weather got worse. 日子一天天过去，天气越变越坏。
2）比较until和till
此两个连词意义相同。肯定形式表示的意思是“做某事直至
某时”，动词必须是延续性的。否定形式表达的意思是“直至某时才做某事”。动词为延续性或非延续性都可以。正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
肯定句：I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
（在肯定句中可用before代替。例如：Let's get in the wheat before the sun sets.）
否定句：She didn't arrive until 6 o'clock. 她直到6点才到。
Don't get off the bus until it has stopped. 公共汽车停稳后再下车。
I didn't manage to do it until you had explained how. 直到你教我后，我才会做。
区别：1）until可用于句首，而till通常不用于句首。
例如：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。
3）until when 疑问句中，until要放在句首。例如：---Until when are you staying? 你呆到什么时候？
--- Until next Monday. 呆到下周一。
注意：否定句可用另外两种句式表示。
4）Not until…在句首，主句用倒装。
例如：Not until the early years of the 19th century did man know what heat is.
直到19 世纪初，人类才知道热为何物。
Not until I began to work did I realize how much time I had wasted.
直到工作，才认识到我已蹉跎了许多岁月。
5）It is not until… that….
例如：It was not until I began to work that I realized how much time I had wasted.
6）表示“一……就……”的结构
hardly/scarcely…when/before, no sooner…than
和as soon as都可以表示“一……就……”的
意思。
例如：
I had hardly / scarcely got home when it began to rain. 刚回家，就下起雨来了。
I had no sooner got home than it began to rain.
As soon as I got home, 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。
例如：
Hardly / Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.

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。
英语状语从句的汉译 [导读]英语状语从句可分为时间、地点、原因、让步、条件、目的、结果、比较和方式状语从句等。 【摘要】英语状语从句可分为时间、地点、原因、让步、条件、目的、结果、比较和方式状语从句等。有些状语从句的位置比较灵活，有前有后。在英语状语从句的汉译中，我们应注意各类状语从句在英汉两种语言中的位置差异，在译文中适当调整语序，相应地译成符合译文表达习惯的状语从句。 【关键词】英语；状语；从句；汉译；探讨 英语状语从句可分为时间、地点、原因、让步、条件、目的、结果、比较和方式状语从句等。有些状语从句的位置比较灵活，有前有后。此外，英语中各类状语从句都有明显的反映其逻辑关系的连接词。汉语的状语从句与英语的状语从句最大区别就在于状语从句的位置和连接词。一般说来，英语中表示方式、比较和结果等关系的状语从句位于主句之后，其它状语从句的位置比较灵活，可前可后。汉语中多数状语从句是放在主句之前，只有比较和结果状语从句位于主句之后，方式状语从句则可前可后。因此，在翻译状语从句时，无论是英译汉，还是汉译英，我们应注意各类状语从句在英汉两种语言中的位置差异，在译文中适当调整语序，相应地译成符合译文表达习惯的状语从句。其次，应注意连接词，分清主句和从句之间的逻辑关系，尤其是在汉译英时，因为汉语造句多用意合法，一些连接词往往省略。英译汉时，还应注意尽量避免机械地照搬连接词的汉语对应词或译义，在准确理解主句和从句间的逻辑关系后，进行相应的句型转换，如将英语的时间状语从句译为汉语的并列句或条件句，地点状语从句译为汉语的条件句等。汉译英时我们还应注意主语的使用。 一、状语从句前置 英语中的时间、地点、条件、原因等状语从句可前可后，而汉语中的这类状语从句一般前置；英语中表示条件的状语从句一般位于句首，尤其是虚拟条件句，这类条件句常常采用顺译法，将从句置于句首；英语中的让步状语从句前后均可，而汉语则前置为多。Culture shock does not seem like a very helpful experience, when you are going through

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.

专题十一状语从句 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。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。

时间状语从句常见的从属连词有：(注意其汉语意义) when, while, as, before, after, since, until (till) once as soon as, the moment, the minute, immediately, directly, each/every time, the first time, the last time, next time, by the time, whenever等。例如：Every/Each time I was in trouble, he would come to my help. I thought her nice and honest the first time I met her.注意：（1）when, while, as的区别： 1)when引导从句时，主从句的动作有先有后，也可以同时进行,从句的动作可以是持续性的，也可以是短暂的。如： When I got to the airport, the plane had already taken off. （主先从后）（短暂性） When I lived there, I used to go to the seaside on Sundays. (同时) （持续性） When the movie ended, the people went back. （从先主后） 2)while侧重主从句动作的对比，且从句的动词必须是持续性的。如： While we were chatting she was looking at the time table on the wall． 3)as引导从句时侧重主从句动作同时或几乎同时进行，从句的动作可以是持续性的，也可以是短暂的。如： Sometimes I watch TV as I am having breakfast． 4）when和while还可以是并列连词，意思分别是“就在这时”，“然而”。如： I was having a rest on the sofa when the telephone rang． They were surprised that a child should work out the problem while they couldn’t .注：并列连词when常用与以下句型中：①…was/were doing…when…（正在做…突然）②…was/were about to do…when…（刚要做…突然）③…was/were on the point of doing…when…(刚要做…突然)④…had just done…when….(刚一…就)⑤Hardly/Scarcely had…done…when…(刚一… 就)(2)before引导从句时,词义非常灵活，注意下列句子中的before的词义： 1.Before I could get in a word, the tailor had measured me.(还没来得及…就) 2.We hadn’t run a mile before he felt tired.(还没…就) 3.We had sailed 4 days before we saw land.(…才…) 4.Please write it down before you forget it.(趁还…没就)(3)till (until) 和not…till (until) 1）till (until):主句谓语动词必须是持续性的，意思是“到…为止“如： He remained there till/until she arrived. 2）not…till (until)…: 主句谓语动词必须是短暂性的，意思是“直到…才”如： She won’t go to bed till/until he returns home. 3）not…until还有强调式和倒装式：强调句：It is not until he returns home that she will go to bed.倒装句：Not until he returns home will she go to bed.(4)几个极易混淆的时间状语从句：1）It was +时间点+when…（当的时候时间是） It was 5 am when we arrived at the village. 2）It was/will be+时间段+before…(没过…就／过了…才) It was/will be two weeks before we met/meet again.3）It is /has been +时间段+since…（自从…以来有…） It is/has been 3 years since we last met.突破点：一看be动词的时态，二看时间段还是时间点。注意：在“It is /has been +时间段+since…”句型中，从句的动词必须是短暂性的，如果是延续性的动词，时间要从从句的动作结束时算起。如： It is 3 years since I smoked.( 我戒烟有三年了) 补充：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner…than…, hardly/scarcely….when….和once这些从属连接词引导的从句都表示 从句的动作一发生，主句的动作随即就发生，常译为“一…就…”。从句中一般时态代替
