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.

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。

I like playing football while you like playing basketball. （3）as引导时间状语从句时表示“当……时，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)，或者一种动作随着另一种动作的变化而变化。 As the time went on，the weather got worse．（as表示“随着……”之意）
时间状语从句讲解讲课教案
（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

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

高考英语语法之：时间状语从句
三大从句是高中最重要的语法点，没有“之一”。对于从句的考察贯穿高考英语试卷的始终，从第一个单项听力，到最后的写作。名词性从句、状语从句以及定语从句三者重要性不分伯仲。 但正如大家知道的，“三大”之一的状语从句，种类繁多。时间、地点、原因、结果、条件、让步、条件、比较、方式9种，基本上大家在经历了学校课堂的洗礼后，也都耳熟能详。殊不知，这9种之中，对于高考来说，重要性的区别是很大的。考频为证，以2006-2010年5年全国高考18个省市的19套卷子的单项选择题为例，涉及到状语从句的题目共有93道，其中时间状语从句考到了24题，条件状语从句26题。孰轻孰重，不多赘述。 与名词性从句不同，状语从句最简单也最直接的办法就是牢固掌握相关连词或者连词词组的中文意思。以时间状语从句为例，需要掌握的连词范围如下： when/while/as/before/after/until/as soon as 1、when: 做“当……的时候”讲，是个尽人皆知的意思，所以高考是不会考到的。相对的，会考到“突然，就在那时”的意思，用以表示从句动作发生的突发性。 2010年全国II卷7题： Tom was about to close the windows _____ his attention was caught by a bird. A. when B. if C. and D. till 鉴于大家都看得明白，不多赘述。 2、while：当初很多老师讲的时候，告诉我们while和when的区别在于前者连接的主从句一定都用进行时态，是不对的。而且，这更不是判断二者区别的办法。 正解：while在同做“当……的时候”讲时，侧重表达主从句动作的对比关系，翻译成“而”字。 e.g. He has b een a father of 2 babies while I?m still single. 2010年全国I卷25题： Mary made coffee her guests were finishing their meal. A．so that B. although C. while D. as if 例句和真题都反复证明了不该在主从句时态上纠结，表示前后动作的对比才是王道。 3、as：同做“当……时”的时候，as更强调主从句动作同时发生，译作“一边……一边……” e.g. As he works, he studies. 他半工半读（一边工作一边读书）。
