状语从句讲解
状语从句
定义：
在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。
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，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:
一、时间状语从句
1.when, while和as的用法
(1)when既可引导一个持续动作，也可引导一个短暂性动作.when强调主从句动作的发生有先后。如：
①When he got there, the classroom had been cleaned.
他到的时候，教室已打扫过了。(主句动作发生在从句动作之前)
②He went to play football when he finished his homework.
做完作业后他就去踢足球了。(主句的动作发生在从句动作之后)
when可作并列连词用，相当于just then，at the time，前一分句多用进行时、be about to或be on the point of doing，表示“正在做..，就在这时发生了另外一件事”或“届时”。如：
①I was reading when he suddenly came in.
②I was about to leave when the telephone rang.
(2)while强调主句动作发生在从句动作所发生的时间段内，从句的动作必须是延续性动词。如：
①Strike iron while it’s still hot.
②Will you please take care of my house while I was away?
在这一情况下，从句的动作一定是延续性动词，如果是非延续动词，要用when。如：
①Will you please take care of my house when I went away?
②当我进来的时侯，他在和别人说话。
While I came in, he was talking with others.
When I came in, he was talking with others.
(3)as引导一个持续性动作，强调主从句的动作同时发生，有“一边..一边..”的意思，也可说明两种正在发展或变化的情况，有“随着..”的意思。如：
①He sang as he walked.他边走边唱。
②As he gets older, he gets more open.
随着年龄的增长，他越发开朗起来。
2.as soon as, the moment, the minute, the second, the instant, no sooner...than, hardly/scarcely...when...，immediately, directly, instantly的用法。
这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一……就……”，The moment she arrives，we can start.
No sooner had we arrived at the station than the train left.
The boy burst into tears immediately he saw his mother.
3.till, until和not...until的用法
(1)在肯定句中，主句谓语动词必须是延续性动词，意为“某动作一直延续到某点才停止”。
You may stay here till/until the rain stops.
你得在这里呆到雨停。
(2)在否定句中，主句谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。He won't go to bed till (until) she returns.
直到她回来他才睡。
(3)not...until句型中的强调和倒装说法。
It was not until you told me that I had any idea of it. (强调句型)
Not until you told me did I have any idea of it. (not until 置于句首，主句要倒装)
Not until he came back did he find his house had been broken into.
4.before和since的用法
(1)连词before表示“还未……就……”，“不到……就……”，“……才……”，“趁还没来得及……”。Before they reached the station, the train had gone.
We hadn't run a mile before he felt tired.
Please write it down before you forget it.
(2)before的句型：It will be＋时间段＋before从句，表示“多久之后才……”。
It will be half a year before I come back.
It won't be long before we meet again.
(3)since的句型：It is/has been＋时间段＋since从句。若从句谓语为非延续性动词，表示“自从……有多久”；若从句的谓语为延续性动词，表示“自从结束/完成……起有多久”。
It is three years since the war broke out.
It is three years since he lived here.
二．地点状语从句
1.地点状语从句可用where, wherever, anywhere, everywhere等引导。地点状语从句可用于主句之前或之后。
You are free to go wherever you like.
Where there is a will, there is a way.有志者，事竟成。
Wherever there is smoke, there is a fire.
无火不生烟(既无风不起浪)。
2.注意区分引导的定语从句与状语从句。
where引导的地点状语从句直接修饰动词，而在定语从句中where作为关系副词要跟在表示地点的先行词后面。
You'd better make a mark where you have any questions.(状语从句)
You'd better make a mark at the place where you have any questions.(定语从句)
三．原因状语从句
1.引导原因状语从句的从属连词有：because, as, since, now that, seeing that, considering that等，每个连词的含义不尽相同。
(1)because用来回答why的提问，语气最强，一般放在主句之后；
(2)since表示既然或已知的理由，稍加分析即可表明的原因，多放在句首；
(3)as多用于口语，语气比because，since弱，表示的理由是明显的或被认为是已知的，是对主句的附带说明，重点在主句，可放在句首或句尾，放在句尾时，as可省略。
I can’t go，(as) I am busy.
(4)considering that, seeing that, now that和since的意义相似，都有“鉴于某个事实”的意思，that 可以省去。
As it is raining, we shall not go to the park.
Now that/Since everybody is here, let's begin our meeting.既然大家都到了，我们就开始我们的会议。
My friends dislike me because I’m handsome and successful.
Now that everybody has come, let’s begin our conference.
四．目的状语从句
引导目的状语从句的从属连词有：so that, in order that, for fear that，in case, lest等。
1.in order that与so that
两个连词都意为“以便……，为了……”，引导的状语从句中需用情态动词；in order that比so that正式，引导的状语从句可置于主句之前或之后，而so that引导的从句只能置于主句之后。
I'll speak slowly so that you can understand me.
In order that we might see the sunrise, we started for the peak early.
The boss asked the secretary to hurry up with the letters so that he could sign them.
2.for fear that, in case与lest这些从属连词本身带有否定意义，意为“以免，以防”，相当于so that...not...或in order that...not...
The boy hid himself behind the tree in case/for fear that his father should see him.
Take your raincoat in case/lest it should rain.
五．结果状语从句
1.引导结果状语从句的从属连词有：so that, so...that...，such...that...。其结构形式为：
Mike is so honest a worker that we all believe him.
＝Mike is such an honest worker that we all believe him.
He earned so little money that he couldn't support his family.
He got up so early that he caught the first bus.
It’s such a good chance that we must not miss it.
区别so...that和such...that的用法
名前such，形、副so，that从句跟在后；多多少少必用so，特别注意是little；“小”用such，“少”用so。
六．条件状语从句
常用引导词：if, unless,
特殊引导词：as/so long as, only if, providing/provided that, supposing that, in case that, on condition that
We’l l start our project if the president agrees.
You will certainly succeed so long as you keep on trying.
Provided that there is no opposition, we shall hold the meeting here.
七、方式状语从句：
引导方式状语从句的从属连词有：as, as if, as though等。方式状语从句应放在主句之后。as引导方式状语从句，意为“按照，正如”；其中as if或as though引导的从句一般用虚拟语气，但如果从句中所陈述的情况很可能实现，也可用陈述语气。
Do as you are told to, or you'll be fired.
The old lady treats the boy as if he were her own son.
When in Rome, do as the Roman do.
She behaved as if she were the boss.
八．让步状语从句

尽管他很有钱，但是他不幸福。
Even though/if it is raining, we'll go there.

Much as I like it I won't buy it, for it's too expensive.
虽然我很喜欢，但我不会买的，因为它太贵了。

语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同，可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样，状语从句的位置比较灵活。既可置于主句之前（通常用逗号与主句隔开），也课置于主句之后（不需要用逗号与主句隔开），有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生，这类从句由从属连词when, while, as引导。 He was hungry when he came home. 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。

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.
高考状语从句讲解
状语从句 一、时间状语从句 1、when, while, as 和whenever when 表时间点，时间段 while 表时间段；有“而”的意思 as “当……”,“一边……一边”，“随着……” whenever 每当，无论什么时候 It is cold when it snows. While there is life, there is hope. While we were speaking, he was reading newspaper. Just as Mrs Richards was entering the dinning-room, there was a knock on the front door. As we age, we trade strength for ingenuity, speed for thoroughness, and passion for reason. 随着年龄的增长，我们用力量换来了机敏，以速度换来了严谨，以热情换来了理智。 注：1)when还可作并列连词，其意义为“那时，这时”，相当于and at this/that time。常用于下列句式： sb.was doing sth.when...某人正在干某事就在这时…… sb.was about to/ going to do sth.when...某人正打算干某事就在这时…… sb.body has just done sth.when...某人刚干了某事就在这时…… 2)如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作时，when，while 与as可互换使用。如： When/While/As I was walking down the street，I came across an old friend of mine. 2、before/ after It will be five years before we meet again.五年之后我们才能见面。 After you think it over, please let me know what you decide. After her husband had gone to work, she sent her children to school. 3、until, till, not...until 1)肯定句：主句的谓语是延续性动词，主从句均为肯定式，意为“某动作一直持续到某时间点才停止”
状语从句讲解及习题附答案
（一）状语从句概述 定义状语从句用作状语，是起副词作用的句子。 位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。 分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。 作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。 （二）状语从句详解 1. 时间状语从句 引导词用法示例 when 意为“当…的时候”。When 引导从句的谓语动词可以 是延续性动词，也可以是 瞬间动词。并且when有 时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。When he arrives, I’ll call you. When you laugh and smile, your body relaxes. while 意为“在…的时候，在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.
的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的， 发生时间较短，一般用于 主句和从句动作同时发 生；as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语， 并且当before引导的从句 位于主句之后，有时译成 “就，才”。当主句用将来时，You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada

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

第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。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。现分别列举如下: 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用。 第一节时间状语从句 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有：2．when，while，as均可表示“当……的时候”。 when强调“特定时间”，表示主句谓语动词的动作与从句谓语动词的动作是同时发生的，或从句的动作发生在主句的动作之前；while表 示的时间是一段，而不是一点，as多用在口语中，强调“同一时间”或“一前一后”，有时还有“随着”的含义。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom．(as有“随着”的含义) as, when, while都表示主、从句的动作或状态同时发生，但三者也有
区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中已有体现），再如： 1 / 18 Mother was worried because little Alice was ill, especially as / when / while father was away in France.妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一边......，一边......”。例如： He looked behind from to time as he went.他一边走，一边不时地往后看。 As time goes on, it's getting warmer and warmer..随着时间的推移，天气变得越来越暖了。 I thought of it just as you opened your mouth.你一张嘴我就知道你要 说什么。（若表示两个短促动作几乎同时发生时，用as的场合多于when.） 当主从句之间表示转折或对比关系时，多用while, 不用as或when。如：

状语从句 在复合句中作状语，位置灵活。 状语从句可分为时间状语从句，目的状语从句，条件状语从句，让步状语从句，地点状语从句，原因状语从句，方式状语从句，结果状语从句。 （一）时间状语从句 1.when, as, while a.when表时间，从句既可以用延续性动词，又可以用瞬间动词。 Eg: When I get there I will call you. 如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be 可省。 Eg：When （you are）in trouble, you can ask her for help. 如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。Eg：When I came into the room(When coming into the room), I found the light was off. b.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。主句的谓语动词 通常是非延续性动词。 Eg: He came in while I was reading a book. 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. As the wind rose, the noise increased. 2.before(在……之前)与after（在……之后） Eg：See me before you leave. I saw them after I arrived. 3. till与until 肯定形式表示的意思是"做某事直至某时"。否定形式表达的意思是"直至某时才做某事"。 Eg: Wait till/untill I call you. 等着直到我叫你。 She didn't arrive till/until 6 o'clock.. 她直到6点才到 但是置于句首时只可用untill. 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。否定形式有另外两种表达方式： (1)Not until …在句首，主句用倒装。 Man did not know what heat was until the early years of the 19th century. =Not until the early years of the 19th century did man know what heat was. (2)It is not until…that… He will not go to bed until his mother comes home. =It is not until his mother comes home that he will go to bed. 4. as soon as/the moment/the instant/the second/the minute/immediately和hardly/scarcely…when, no sooner…than a. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和从句的动作同时发生。译为“一……就” Eg：As soon as she heard the news, she began crying. b. hardly/scarcely…when, no sooner…than都可以表示"一……就……"的意思，但主句谓语动词一般要用过去完成时，从句谓语动词要用一般过去时。 Eg：I had hardly / scarcely got home when it began to rain. 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. No sooner had I got home than it began to rain。 1. We called the First - Aid Center_______ the traffic accident happened. A. immediately B. shortly C.quickly D. hurriedly 2.
