时间状语从句
英语语法状语从句的归纳总结
在复合句中修饰主句或主句中的某一成分的从句叫状语从句。状语从句通常由从属连词或起连词作用的词组引导，有时甚至不需要连词直接和主句连接起来。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。
一、时间状语从句
时间状语从句是表示时间关系的从句。可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，通常可分为以下几种情况：
A． when, while, as, whenever
when, while, as表示主句谓语作和从句的谓语动作同时发生或几乎同时发生。
1．when
①when表示点时间时，从句中用短暂性动词；表示段时间时，用持续性动词。
When I got home, my family were having dinner.
我到家的时候，全家已在吃晚饭。
（when表示点时间）
When they were still talking and laughing，the teacher came in.
当他们还在说笑的时候，老师进来了。（when表示段时间）
He waved hello when he saw her.
当他看见她的时候，就挥手打了个招呼。（when表示点时间）
When you think you know nothing, you begin to know something.
当你认为自己一无所知的时候，就开始知道一些事情了。（when表示段时间）
注意：
当when意思是正当……时候（and at that moment）时，when只能跟在前一分句之后。 He was about to go to bed when the doorbell rang.
他正要上床，忽然门铃响了。
They were watching the World Cup when suddenly the lights went out.
他们正看着世界杯比赛，突然灯灭了。
They had just arrived home when it began to rain.
他们刚到家，天就开始下雨了。
②有时when表示虽然，尽管的含义，相当于although或since。
He walks when he might take a taxi.
尽管可以打的，但他还是步行。
How can you hope for mercy yourself when you show none.
既然你不宽恕别人，你自己又怎能希望得到别人的宽恕呢？
2．while
①while通常表示一段时间，从句中宜用持续性动词作谓语。
Strike while the iron is hot.
趁热打铁。
She fell asleep while she was reading the newspaper.
她在看报的时候睡着了。
②while有时可以作并列连词，表示对比，可译成……而……。
I am fond of English while he likes maths.
我喜欢英语而他却喜欢数学。
We slept while the captain kept watch.
我们睡觉而上尉担任警戒。
③while有时可引导让步状语从句，意思是虽然。
While they love their children, they are strict with them.
虽然他们都爱他们的孩子，但却对他们要求严格。
提示：
虽然during 与 while 意思很相近，但是during是介词，不能引导从句。
3．as
①as表示点时间时，从句中用短暂性动词；表示段时间时，用持续性动词。as和when两者经常可以通用。
The thief was caught as when he was stealing in the supermarket.
小偷在超市行窃时被逮住了。
②as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。
They talked as they walked.
他们边走边聊。
He looked behind from time to time as he went.
他一边走，一边不时地往后看。
③as表示随着
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。
As spring warms the earth, all flowers begin to bloom.
随着春回，百花开始绽放。
4．when, while, as的用法区别
①只有当从句表示的是段时间，即其谓语动词有持续性特征时，这三者可以通用互换。
I got the news on the radio when/ while /as I was having breakfast.
我在吃早饭的时候从收音机里获悉这一消息。
②在下列情况下，三者彼此之间不能替换使用：
a．as更强调同一时间或紧接的一前一后或伴随着的变化。

我们听着歌星边弹吉它边演唱。
I thought of it just as you opened your mouth.
你一嘴我就知道你要说什幺
As he grew older, he became less and less active.
随着他年龄的增长，他变得越来越不活泼了。
提示：
状语从句可放在主句之前或之后，放在主句之前时一般用逗号与主句分开。有时可置于主句中间，前后用逗号。
b．when更强调特定时间，还可表示从句中的动作先于或后于主句的动作。
When I had given Mary the spare ticket, I found my own already gone.
当我把多余的票给了玛丽时，我才发现我自己的票已不知去向。（从句动作发生在主句之前，注意主从句的时态）
When I finally got there, he meeting had been on for ten minutes.
当我最终赶到那里时，会议已开始十分钟了。（从句动作发生在主句之后，注意时态）
c．while从句只能表示延续的动作或状态或主从句中动作的对比。
She thought I was talking about her daughter, while in fact, I was talking
about my daughter.
她以为我在谈论她女儿，而事实上，我在谈论我的女儿。
d．若表示两个短促动作几乎同时发生时，用as场合多于when。
As he finished his speech, the audience burst into applause.
他结束讲话时，观众爆发出雷鸣般的掌声。
5．whenever
whenever是when的强势语，它描述的不是一次性动作，而是经常发生的习惯性动作。

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。
时间地点原因状语从句
地点状语从句 常用连词：where 特殊连词：wherever (在……的任何地方), anywhere, everywhere 【点拨】地点状语从句与定语从句的区别：where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。 Go back where you came from.(where引导地点状语从句)你从哪儿来回哪儿去。Go back to the village where you came from. (where引导定语从句，修饰village)回到你来的那个村子里去。 时间状语从句 常用连词：when, as, while, as soon as, before, after, since , till, until, whenever (每当，一……就……) 特殊连词：the minute, the moment, the second, every time, the day, the instant, immediately, directly, no sooner ... than, hardly ... when, scarcely ... when 1．由when, while, as引导的时间状语从句when，while，as都有“当……时候”的意思。 1) when引导的从句的谓语动词既可以是延续性动词，又可以是瞬间性动词，并且when有时表示“就在那时”，相当于and at that time。 It was raining when we arrived. (指时间点)当我们到达的时候，天正在下雨。 When we were at school, we went to the library every day. (在一段时间内) 我们在学校上学的时候，每天都去图书馆。 We were about to leave when he came in.我们刚要离开，就在那时他进来了。 2) while引导的从句的谓语动词必须是延续性的，并强调主句和从句的动作同时发生(或者相对应)，此外，while有时还可以表示对比。 I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。(对比) He fell asleep while/when reading.看书的时候，他睡着了。 Strike while the iron is hot. (用as或when不可以，这里的while意思是“趁……”) 趁热打铁。 3) as表示“一边……一边”，as引导的句子的动词是延续性的动词，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。 We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”) Our headmaster laughed as she spoke.我们的校长边谈边笑。 2．由before“在……之前”和after“在……之后”引导的时间状语从句。 It will be four days before they come back．他们要过四天才能回来。 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。 After you think it over, please let me know what you decide. 你仔细考虑过以后，请告诉我你是怎样决定的。
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.
时间原因条件状语从句
掌门1对1教育高中英语 时间、原因、条件状语从句 一．when, while 和as 引导时间状语从句的区别用法（一）when 的用法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。（口头练习） When I got to the airport, the guests had left. Why do you want a new job when you have got such a good one already? (二)while 的用法 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。而另一件事的状态根据具体情况而定。（口头练习） 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看，while 表示的是一段时间，是一个过程。 趁热打铁。Strike while the iron is hot.（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。） (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。as 从句用的一般不用正在进行时，而只是一般过去时。可以翻译成“边……边……”。（口头练习） As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. 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，常常翻译成“随着……”之意。 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。（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。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。）
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
