中考英语复习时间状语从句语法及练习(无答案)
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.
3. Were you writi ng whe n the teacher came in?老师进来的时候，你在写信吗？
4. Sorry, I was out whe n 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：
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 从句大凡用的是正在进行时。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 talki ng, the bell ran g.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从句例外的是，as从句用的大凡不用正在进行时，而只是大凡过去时。as
从句大凡可以翻译成边?…边..... 。例如：
1. As my mother sang those old songs, tears ran down her cheeks.
2. The stude nts took notes as they liste ned 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，气候更加倒
I—>
霉。
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 goi ng out, it began to sn ow合法我们出门时，雪开始下起来。
3. He came in as I was goi ng to be（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. Whe n /While /As we were dancing, a stra nger came in .[da nee 为延续性动词]
2. Whe n /While /As she was maki ng a phone call, I was writ ing a letter. [make为延续
五、比较while, when, as
1 ）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凑巧与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，主句用大凡过去时）（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 un til mid night.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 她直至“ 6lo点才到。
Don “t get off the bus until it has stopped^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：
---U ntil whe n are you stayi ng?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 禾口until
在日常英语教学中，我们遇到学生问这样的一些问题：
1. ___________________________ Hewillspendsixhoursathisdesk he finishes his
composition.
A.before
B.until
C.after
D.when
2. ___________________ The bike hit the tree I could get off.
A.when
B.before
C.while
D.until
3.I knocked at the door for more than five minutes ___ Mrs white answered it.
A.until
B.when
C.after
D.before
4.It was ___ y esterday ___ be ___ the secret.
A.not until ；that；knew
B.until；when；knew
C.not before；that；found
D.before；that；didn “t find 怎样才能清晰地解释其选择的
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，就能简易地解决这类问题。现详细阐明如下：一、在下列情况下，两者可互换用，但含义略有例外。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。多见的动词是
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 backourentiitl/ibsedfark.
(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。例
如：(1)He livedwith his parents until/before he graduated from school.
(2)I will wait until/before he comes to my help.
(3)I shall stay heer until/before you come back.
二、在下列情况下，用before 不用until 。1.主句这肯定式、终止性谓语动词，只用before 。例：(1)He fell asleep before I could take off his clothes.
(2)We arrived there before it atarted to rain.
2?主句谓语动词强调动词的迟缓性，只用before，常伴有时间段状语或时间段暗示。例：(1)It was quite some time before he found the elephant at all.
(2)We had walked a long way before we found some water.
3?如果强调从句谓语动作未发生，就发生主句谓语动作，只用before。常译
为未及”不”或不等?…就”例：
(1) We can leave early in the morning before it gets too hot.
(2) I must write it down before I forget it.
(3) We do want to buy something now before prices go up.
4?表与其说?…倒不如” 与其…?毋宁 .... 只用before。例：
(1) I would give up my job before I “ d agree to be dismissed.
(2) He will die of hunger before he will steal.
5.在某些特定句型中用before。例如：
(1)It was not long before the whole country rose up.
(2)It will probably not be long before they understand each other.
三、下列情况大凡区别用until 。
1. 主句是持续性谓语动词时，肯定、否定都可以，但意义完全例外。肯定表动作终止，而否定表动作开始。例如：
(1)We discussed the problem until/before he came back.
(2)We didn “ t discuss the probluenmtil he came back.
2. not…unt句型尽管在某些情况下可与before互换用，但在强调句中大凡仍用
until 。
(1) It was not until he told me that I knew it.
(2) It was not until he finished his homework that he went home.
综上所述，前面的4 条选择题中，第1、3 题强调动作发生的迟缓性应选before。
第2题表动作未及发生就发生主句动作也应选before。第4题为强调句应
选A 项。
(五)其他时间状语从句的用法
1?由since引导的时间状语从句。
since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。大凡情况下，从句谓语动词用大凡过去时，而主句的谓语动词用现在完成时。但在It is+时间+ since从句的句型中，主句多用大凡现在时。例如：
I have bee n in Beiji ng si nee you left自从你离开以来，我一直在北京了。
It is five mon ths since our boss was in Beiji ng我们老板离开北京有五个月了。
知识扩展
1. It is since 从。。。以来多长时间了（因为since +从句或名词，表示一段时间）lt is five years si nee we met last time从我们上次见面已经五年了。
2. It is +before 。。。…才）
lt was a long time before l went to sleep again.
It was an hour before（= un til） the police arrived.
2. 由as soon as, immediately, direetly, instantly, the moment, the instant, the mi nu te,等引导的时间状语从句。
这些连词都表示一…?就”例如：

初中英语语法专题讲座——状语从句 状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表： 时间 when, while, as, as soon as, since, until, after, before，as long as（长达……之久） 条件 If, unless,as/so long as(只要) 原因 As, because, since，as/so long as(既然,因为) 地点 Where 目的 So that(为了), in order that 结果 So that（方便）, so…that,such…that 让步 though, although, even if, however 方式 As 比较than, (not)as…as, 时间状语从句： Whenever he comes, he brings a friend. 他每次来都带个朋友。 They all continued their regard for me as long as they lived. 他们毕生都在关心着我. 条件状语从句： As long as I am alive, I will go on studying. 只要我活着，我就要学习。 原因状语从句： Since we live near the sea, we enjoy nice weather.由于我们住在海边，能享受到好的天气。 地点状语从句： Put it where we can all see it.把它放在我们都能看到的位置。 目的状语从句： Finish this so that you can start another.把这个做完，（为了）你可以开始另一个。 结果状语从句： He was so angry that he couldn't say a word. 他气得说不出话了。 让步状语从句： Though he is in poor health, he works hard.虽然他身体不好，但是他工作很努力。
英语语法之时间状语从句
时间状语从句常由以下连接词引导：when（当……时），as（一边……一边；当…时），while（在……期间），after（在……之后），before（在……之前），as soon as（一……就），since（自从），till(until)（直到……，直到……才），whenever（任何时候），the moment（一……就），no sooner than（一……就），hardly…when… （一……就）等。由以上连接词（或词组）连接的主从复合句中，主句和从句的动作，有的是同时发生，有的是先后发生。因此，要特别注意根据连接词所代表的时间不同，主句和从句的谓语要使用相应的时态。这是掌握时间状语从句的关键。 1. when 和whenever 引导的从句：从句的动作和主句的动作可以同时发生，也可以先于主句的动作发生。例如： When we reached home, it was already dark. 我们到家的时候天已经黑了。 When my cousin came yesterday, I was playing volleyball. 昨天我表哥来时，我正在打排球。 When it rains, I go to school by bus.下雨的时候，我坐车去学校。 I shall tell her the good news when she comes. 她来时，我将告诉她这个好消息。（主从句都表示将来发生的动作，但要注意从句中要用一般现在时，表示将来。） Come to see us whenever you can.你什么时候有空，就过来看看我们。 2. while 和as 引导的从句：while表示“当…过程中”，强调某一段时间主句和从句的动作在同时发生。as表示“当…时”或 “一边…一边”，主句和从句的动作同时发生。例如： Work while you work; play while you play. 该工作的时候就工作，该玩的时候就玩。 While he is reading, he always makes notes. 他经常一面看书，一面做笔记。 She sings as she goes along.她边走边唱。 You will grow wiser as you grow older. 随着年龄的增长，你会更加聪明起来。 3. before 和after 引导的从句：前者一般表示主句的动作发生在从句动作之前。后者表示主句的动作发生在从句动作之后。 例如： I didn’t know any English before I came here. 我来这儿之前，一点英语都不懂。 I had written my report before my mother came back.

状语从句 状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，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，让步状语从句。 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： When while as 的区别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. 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。 例如： The young man read till the light went out（熄灭）. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off（从下来）until the bus stops. 【。固定组合里from morning till night，till/until是不能替换的，】 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don’t leave the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“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： Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill. As it is raining, we shall not （不得；不应该）go the zoo. Since you can’t answer the question, I’ll ask someone else.
高中英语语法状语从句 归纳总结
状语从句 一．分类： 种类连接词注意区别： 时间状语when/whenever/while/as/before/after/instantly /until/till/by the time/as soon as/hardly…when /no sooner…than/the moment/the minute/immediately 有一些表示时间的名词短语也可用来引导时间状语从句： the?minute,?the?moment,?every?time,?the?first?time 例：The?moment?he?reached?the?country,?he?started?his? search. 他一到达这个国家，就开始他的探寻工作。 有一些表示时间的副词也可用来引导时间状语从句： directly 例：Directly?the?master?came?in,?everyone?was?quiet. 校长一进来，?大家就安静下来 as和when、while： as, when 引导短暂性动作的动词。当从句的动作发生于主句 之前，只能用when 引导这个从句，不可用as 或while。从 示"随时间推移"连词能用as，不用when 或while。 till/until和not…till/until： until可用于句首，而till通常不用于句首。 地点 状语 where//wherever where，表示某一个；wherever，表示任何一个。 原因状语Because/as/since/now that/for because和since、for、as、now that： because语势最强，用来说明人所不知的原因，回答why提 问题。当原因是显而易见的或已为人们所知，就用as或si 由because引导的从句如果放在句末，且前面有逗号，则可以用 来代替。但如果不是说明直接原因，而是多种情况加以推断 只能用for。now that都表示“既然”now that一定要是现在 的，since可以是现在，也可以是过去和现在。 条件状语if/unless/once/in case/as long as/on condition that 多用一般时态，如果表示一般将来的情况，就用一般现在时 果表示过去将来的情况，就用一般过去时。 目的状语(so) that,/in order that/for fear that/in case/lest so that和in order that后常接may, should, could, would等情 词 结果状语so…that, such…that 其规律由so与such的不同词性决定。such 是形容词，修饰 或名词词组，so 是副词，只能修饰形容词或副词。so 还可 示数量的形容词many, few, much, little连用，形成固定搭配 比较 状语 Than/not so//as…as//the more…the more Your watch is not the same as his.(the same as结构)方式 状语 as if, as though, as, (just)as---so，as if 和as though引导的从句一般用虚拟语气。 让步状语 Though/although/even if/even though/ as//, no matter what/who/which/how/when，whatever/whoever /whichever/however/whenever ，whether---or---（不管---- 都） as在让步状语从句中常用倒装形式；although和though用正 序，可和yet连用，但不可和but连用 时间状语从句：
英语语法大全之方式状语从句
英语语法大全之方式状语从句 方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：Always do to the others as you would be done by. 你希望人家怎样待你，你就要怎样待人。 As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： They completely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。） He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He stared at me as if seeing me for first time. 他目不转睛地看着我，就像第一次看见我似的。 He cleared his throat as if to say something. 他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger. 波涛冲击着岩石，好像很愤怒。 https://www.360docs.net/doc/5619158424.html, 北京微课创景教育科技有限公司- 1 -
