初中时间状语从句语法及练习教案资
英语时间状语从句讲解与练习（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 从句用的最多的是大凡过去时，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。
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 多数情况下用的是大凡过去时，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？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。
时间状语从句讲解和练习(答案)
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。
时间状语从句(含练习及答案)
以when 引导的时间状语从句- When I got home, my son had finished his homework. (主句动作发生在从句之前)- When(当...时候, 主语+did) we arrived, it was raining.- When(正当...时候，主语+be+doing) I was playing the computer games, my mum came in. - He is always nervous when he speaks to strangers.- I usually walk to school when it rains.以while 引导的时间状语从句- While I was reading, my brother was playing with his toy cars. (主从句子动作同时发生)- While/When/As he was studying in the library, I saw him. (表示一段时间时，while/when/as 可替换)while引导的从句的谓语动词必须是持续性动作:I saw him while(x) I was getting off the bus.(x)I saw him when/as I was getting off the bus.以as 引导的时间状语从句- He will grow wiser as he grows older. 随着年龄的增长，他会聪明起来。
（随着，表示时间的推移，这时，不用when/while）- He entered the room as/when/while the meeting was going on. 正当开会的时候，他走进房间。
以before引导的时间状语从句- He had washed his hands before he had dinner. (主句动作先于从句动作)- Please clean the house before you move in.以after 引导的时间状语从句- She went on holiday after she had taken the examination. (从句动作先于主句)- You can watch TV after you finish your homework.以since 引导的时间状语从句- She has been in the house since she came to the city. (主句完成时态，从句过去时)- I have taught them English since last year.以as soon as引导的时间状语从句- I will write to you as soon as I get to America. 我一到美国就会给你写信。

1. 时间状语从句(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。

例如：I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。
如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。
英语时间状语从句讲解与练习(完整版)
英语时间状语从句讲解与练习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。

英语时间状语从句解说（一）when,while和as指引时间状语从句的用法一、when的用法假如只从现象来看，when从句用的最多的是一般过去时，而主句的时态没有限制,依据详细状况而定。
1.Whenhewasachildhewasalwaystryingoutnewideas. Wereyouwritingwhentheteachercamein?老师进来的时候，你在写信吗？Sorry,Iwasoutwhenyoucalledme.对不起，你打电话来的时候我出去了。
when 从句的要点不在动作自己发生的状态，而不过把它作为一个时间点，所以when多半状况下用的是一般过去时，则不用正在进行时。
由于假如用正在进行时，它表示的就是一段时间而不是一个时间点了。
依据这一点，有的文章增补说：when从句的动词大多是刹时动词。
这种说法也能够参照。
实质上，when从句也能够有其余的时态，但几乎也不用进行时，由于它也不过作为一个时间参照点。
比如：Whenhehadfinishedhishomework,hetookashortrest. Whydoyouwantanewjobwhenyouhavegotsuchagoodonealready?二、while的用法对比于when来说，while从句的重视点就不同样了。
while从句的重视点在于描绘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，依据详细状况而定。
比如：Whilemywifewasreadingthenewspaper,IwaswatchingTV. WhileJimwasmendinghisbike,LinTaocametoseehim. Whiletheyweretalking,thebellrang.正在他们讲话的时候，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。

英语时间状语从句讲解与练习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 someoneknocked 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。

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。
2. The atmosphere gets thinner and thinner as the height increases.3. As years go by，China is getting stronger and richer.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.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。
1. When /While /As we were dancing, a stranger came in. [dance 为延续性动词]2. When /While /As she was making a phone call, I was writing a letter. [make为延续五、比较while, when, as1）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.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.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.（二）before和after引导的时间状语从句1．Before是主句动作发生在从句的前面。
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引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。
2．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。
After we had finished the work, we went home.（从句用过去完成时，主句用一般过去时）（三）比较until和till 的用法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。
（四）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.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.Not until I began to work did I realize how much time I had wasted.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. （四）巧辨before和until在日常英语教学中，我们遇到学生问这样的一些问题：1.He will spend six hours at his desk____he finishes his composition.A.beforeB.untilC.afterD.when2.The bike hit the tree____I could get off.A.whenB.beforeC.whileD.until3.I knocked at the door for more than five minutes____Mrs white answered it.A.untilB.whenC.afterD.before4.It was____yesterday____be____the secret.A.not until；that；knewB.until；when；knewC.not before；that；foundD.before；that；didn't find怎样才能清楚地解释其选择的原因，这就涉及到until与before的区别问题。
实际上，只要我们把握住两者使用时本身的含义及主句动词是终止性的，还是延续性的，肯定式，还是否定式两大点，就能容易地解决这类问题。
现详细阐明如下：一、在下列情况下，两者可互换用，但含义略有不同。
before表示“在……之前”的意思，强调时间先后关系；而until表示“直到……才”的意思，主句是肯定句则表示主句动作的终止时间；主句是否定句则强调主句动作的起始时间。
1.主句为否定式终止性谓语动词。
常见的动词是open,start,leave,arrive,finish,stop等。
例如：(1)The noise of the street didn't stop until/before it was midnight.(2)The children won't come back until/before it is dark.(3)I didn't leave the lovely boy until/before his mother came home.2.主句为肯定式、延续性谓语词，这类动词用stand,stay,talk,be,wait等。
