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。
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.
7．until 引导的从句：表示一个动作持续到某一时刻。
（1）表示“直到……”，如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。
（2）表示“直到……才”，主句用否定式，从句用肯定。如果主句中的谓语动词是瞬间动词时，必须用否定形式。
例如：They worked until it was late. 他们一直工作到天黑。
She didn’t go to bed until she finished her homework. 她写完作业才睡觉。
小试牛刀：All the people left. He waited.(until)________________________________________ He went to bed . his father came home.________________________________________
8．as soon as 引导的从句表示“一……就”，强调动作紧密相连。
例如：As soon as she came to the classroom, she began to read English.她一到教室，就开始读英语。小试牛刀：We start to sing. It''s 12 o''clock. (as soon as)________________________________________
9. by the time 到。。。为止 (所在句子的主句应用完成时)
例如：By the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。
小试牛刀：By the time I got to school, the class .（begin）我到校时，已经开始上课了。
知识扩展
1. it is +时间段+since+一般过去时（从。。。以来多长时间了）
例如：it is five years since we met last time.从我们上次见面已经五年了。
2. it is/ will be +时间段+before+一般现在时， it was+时间段 +before+一般过去时 (。。。才)
例如：it is a long time before I go to sleep . 过了很长时间我才睡着。
it was an hour before the police arrived.过了一个小时，警察才来。
小试牛刀：It_____(be) ten years since we ________(leave) that city .
It is reported that it may be two or three months_____it is possible to test this medicine on animals
How long do you think it will be ______ China sends a manned spaceship to the moon？3、when和while的区别
4、巧记10个瞬间性动词
在学习以when和while引导的时间状语从句时，用到了瞬间动词和延续动词。常见的瞬间动词有
die(死)，come(来)，go(去)，eave(离开)，arrive(到达)，begin(开始)，buy(买)，,join(加入)，borrow(借进，借出)，return(归还)等。
这10个瞬间动词可用两句口诀来帮助记忆: 开始离去,借来还, 出生入死,买到家。
注释:
1."开始离去,借来还"为begin,leave,go,borrow,come,return六词；
2."出生入死,买到家"为join,die,buy,arrive四词。
3.各词改为相应的延续动词为：
begin→be on, leave→be away from, borrow→keep, go→be, come→be here, return→be back, join→be in, die→be dead, buy→have, arrive→be here等。'
5、状语从句与主句的时态问题
1.由when、while引导的时间状语从句的时态：（主过从过）
主句（过去进行时）+when +从句（一般过去）
主句（一般过去时）+when +从句（过去进行时）
主句（一般过去时）+while +从句（过去进行时）
主句（过去进行时）+while +从句（过去进行时）
注意：看动词为短暂性动词用一般过去时，动词为延续性动词则用过去进行时。
小试牛刀：Mother （cook）supper when I (get) home yesterday.
Last Sunday I (meet) Lin Hong when I (walk) in the street.
When the students (have ) a meeting, the teacher (come) in.
While Han Meimei (sweep) the floor, Lucy (carry) water.
2. 由when、after、before、by the time引导的时间状语从句的时态：
主句、从句的谓语动词都已完成，则先发生的动作用过去完成时，后发生的动作用一般过去时。
例如：After he had finished his work, he played a game of chess with his friend.
小试牛刀：When they (get) to the cinema last light, the film (start).
I (go) out with my friends after I (finish) all the homework last night.
3.时间状语从句与主句的时态不一致。（主将从现：主句用将来时，而时间状语从句用一般现在时）
小试牛刀：As soon as I reach Canada, I you up. (ring)
I will call you as soon as I the result. (know)

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.

(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.

语法专题复习（四）状语从句讲解 状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、 非谓语动词、定语、状语或整个句子。 一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解 和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。现分别列举如下: 1．I fell asleep when he was doing his exercises .他正作练习时我睡着了。（时间状语从句） 3．She always singsa s she walks . 她总是一边走一边唱。（时间状语从句） 4．I waited until he had finished his work . 我等到他做完活。（时间状语 从句） 5．It was not long before he told me about this affair . 不久，他就告诉我 这件事。（时间状语从句） 6．He has worked very hards ince he entered the factory 自从他进厂，工 作一直很努力。（时间状语从句） 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day，the ins tant, immediately , directly, no sooner ?than, hardly ?when, scarcely ?wh en
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

I know how to light a camp fire because I had done it before .（原因状语从句） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard.

She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句

He knocked at the door , when my mother was sleeping. 2.由while引导的时间状语从句“与…同时，在…期间”，谓语动词必须是延续性动词。EG：Lucy was cleaning the room while Lily was listening to music. 3. 由before/after 引导的时间状语从句，before“在…之前”，after“在…之后” Eg：He went to the office before he visited Mr. Zhong. I called Betty after I finished the homework. 4. 由until引导的时间状语从句，“直到…为止”，not until “直到…才” Eg：He stayed in the room until his mother came back . We didn’t begin the meeting until the boss came. 5. 由as soon as 引导的时间状语从句，“一…就” Eg：I took out the notebook as soon as the class began. 四．时间状语从句要注意的几个地方 （1）例如： It was raining hard（rain hard 下大雨）when got to school yesterday. While he was doing his homework, the telephone rang. As he walked along（沿着走）the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back.

I met her while I was in school. c. as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行。同时可表示主句的动作随着从句的动作的变化而变化。 Eg: He jumps as he sings.

I had no sooner got home than 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：Hardly / Scarcely had I got home when it began to rain.

初中时间状语从句语法及练习
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。
