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 goi ng OUt Whe n 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 Whe n She comes. 她来时，我将告诉她这个好消息。
小试牛刀：I found mother cooki ng for me. I got home.(when) _____________________________________ He WaS liste ning to the radio Whe n 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 rai n. We Were playi ng football.(while) _____________________________________ LUCy WaS clea ning the room ________ Lily WaS liste ning 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。
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。
状语从句讲解与练习
状语从句讲解与练习一、时间状语从句定义：用从句来表达一件事情或一个行为发生的时间(一) before & afterbefore：“在……之前”，主句动作发生在从句动作之前[主前从后]after：“在……之后”，主句动作发生在从句动作之后[主后从前]He called me after he finished his homework.He had learned English for three years before he went to London.(二)as soon as 一……就…… [主将从现]表示从句动作一发生，主句动作马上就发生。
I'll tell her everything as soon as she comes back.As soon as I reached Canada, I rang him up.(三) since 自从(1) 主句【现在完成时】+ since时间状语从句【一般过去时】He has gone abroad since he was 20.(2) It’s + 一段时间+ since时间状语从句【一般过去时】It is 10 years since we became friends.(四) until(1) 用于肯定句中，表示主句的动作一直持续到从句动作发生或状态出现时为止。
一般可译为“直到……为止”。
主句的动词必须是延续性的。
He will stay here until his mother comes back. [主将从现](2) until用于否定句中，表示主句的动作在从句的动作发生之后才开始。
一般可译为“直到……才……”或“直到……之前不要……” 。
主句的动词多为非延续性。
Don”t get off the bus until it has stopped.The little girl didn’t stop crying until she saw her mom.(五) when & while & as(1) 理论基础①三者都可表示“当……时”② while只接持续性动词，when/as持续、短暂都可以接③while 多用于进行时态，when多用于一般时态(2) 一般时while进行；进行when一般时The telephone rang while I was taking a bath.I was reading a newspaper when he came in.(3) 事件对比用while（然而；却）Father was preparing a report while I was playing PC games.He likes coffee while she likes tea.(4) “随着”/“一边…一边”用asThings are getting better and better as time goes on.She sang as she went along.二、原因状语从句because 因为（不与so连用）(1) because &because ofbecause引导原因状语从句because of 是介词短语，后跟n./pron./V-ing，句中作原因状语-- Why didn't he come here?-- He didn’t come here because he was ill.-- He didn’t come here because of his illness.(2) because & for & since & asbecause 语气最强烈；for放句中，用来表示一种附带或补充解释、说明；since & as 通常放句首，作“既然”讲。

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。

初二英语时间状语从句讲解与练习一、when 的用法when 从句的重点不在动作本身发生的状态，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when 从句的动词大多是瞬时动词。
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。
二、while 的用法while 表示的是一段时间，是一个过程。
：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。
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。

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。
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。
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. 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。

完整版)初中时间状语从句语法及练习(全)
完整版)初中时间状语从句语法及练习(全)状语从句是复合句中起修饰作用的从句，用来修饰说明谓语，包括地点、时间、原因、目的、结果、条件、让步、比较、方式和伴随状况等方面。
状语从句可以在句首或句末，从句后面常用逗号与主句隔开；放在句末时，从句前面往往不用逗号。
状语从句可以分为时间、地点、原因、目的、结果、让步、比较、方式和条件状语从句。
时间状语从句的从属连词有when。
while。
as。
before。
after。
till/until。
since。
whenever。
as soon as等。
主句和从句的时态一般是主将从现、主情从现、主祈从现。
When引导时间状语从句时表示“当……的时候”，既可以指时间段也可指时间点，从句中既可用延续性动词又可用瞬间性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。
当when引导的时间状语从句中一般用一般现在时表将来（主将从现）。
例如：I will call you when I get there。
While和as与when类似，都表示“当……的时候”，但while更强调主句和从句的动作同时进行，as则更强调主句和从句的动作相互呼应。
例如：While I was reading。
he was watching TV。
As I was leaving。
the phone rang.Before和after分别表示“在……之前”和“在……之后”，从句中用一般过去时表示过去的动作或用一般将来时表示将来的动作。
例如：I finished my homework before my mother came back。
After he finishes his work。
he will go to the gym.Till/until表示“直到……为止”，从句中用肯定句表示肯定的动作或用否定句表示否定的动作。
例如：I will wait for you until you finish your work。
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。
八年级下册状语从句讲解及练习
八年级下册状语从句讲解及练习状语从句是用来修饰主句中的动词、副词和形容词的从句。
根据含义，状语从句可以分为时间状语从句、地点状语从句、条件状语从句、原因状语从句、结果状语从句、比较状语从句、目的状语从句和让步状语从句。
时间状语从句通常由when、as、while、before、after、since、till、until、as soon as等连词引导。
例如，昨天我到学校时正下着大雨。
他正在做作业时电话响了。
在时间状语从句中，通常不使用将来时态，而是使用现在时态表示将来的动作或状态。
例如，我一到纽约就给你打电话。
在带有till或until引导的时间状语从句的主从复合句中，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。
例如，年轻人看书看到灯灭了。
让我们等到雨停了再走。
条件状语从句通常由if和unless引导。
例如，如果明天下雪了，我们该怎么办？除非我告诉你，否则不要离开大楼。
在条件状语从句中，谓语动词通常使用现在时态表示将来的动作或状态。
例如，如果明天有空，我会帮你学英语。
除非他病了，否则他不会迟到。
祈使句+ and (or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。
例如，赶快，否则你会迟到。
如果你不赶快，你会迟到。
努力研究，你就能通过考试。
If you work hard。
you will XXX.XXX like because。
since。
and as。
For example。
"He didn't come to school because he was ill." As and since are weaker than because and are often used to express XXX "why," only because can be used。

初二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 thebank.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, 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.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。
