时间、条件和让步状语从句
时间、条件和让步状语从句在高考中约占3分，考查形式主要有单选、完型填空、语篇填空和改错，主要考察这三种从句中的引导词、谓语动词。
幻灯片3
一、时间状语从句
1．no sooner...than与hardly...when
都表示主句与从句的动作相继发生，意为“一……就……，刚刚……就”，主句动词用过去完成时。如no sooner，hardly位于句首时，主句用倒装形式。
He had hardly gone to bed when the doorbell rang.
＝Hardly had he gone to bed when the doorbell rang.
他刚睡下门铃就响了。
No sooner had he got off the train than his daughter ran towards him.
他刚下火车，他女儿就向他跑了过来。

2．as soon as，the moment，immediately
引导的从句表示从句动作一发生，主句动作随即发生，常译为“一……就”。名词词组the second，the minute，the moment，every time，any time，next time，the first/last time，the day/week/month等亦可作连词，引导时间状语从句。
They told me about it as soon as/immediately/the moment they got the message.他们一听到口信就把消息告诉了我。
Every time he walked by the lake，he thought of his childhood life.每当他走过那个湖时，就会想起童年的生活。
注意：immediately可用做连词也可用做副词。

3．till和until
词义是“直到……，一直……为止”，表示一个动作持续到某一时刻或某一动作发生为止，在句首只能用until。在肯定句中，主句中要用延续性动词；在否定句中，可以用非延续性动词。
She stood there till/until he had passed out of sight.
她站在那里看着，直到望不见他的身影。
Until they had finished the work，they did not go home.
＝Not until they had finished the work did they go home.
直到工作完成了他们才回家。
幻灯片6
注意：(1)在not...until结构中not until位于句首时主句部分倒装。在强调句中，强调until 引导时间状语时，常把not提前，构成It isn’t/wasn’t until...that...。
(2)not...until和not...before意思相同，表示“直到……才，在……以前不”。
幻灯片7
4．before和since
(1)若表达“还未……就……”“不到……就……”“……才……”“趁，还没来得及”时，需用连词before。
He had put the broken vase away before his mother came back.
他趁妈妈还没回来就把打碎的花瓶收拾好了。
(2)It will be＋时间段＋before sb.do(does)“多久之后才……”。
It will be 3 days before our manager signs the agreement.
要过3天后经理才签那份协议。
幻灯片8
(3)since从句的谓语动词一般是非延续性动词，主句的谓语动词是延续性的或者是表示反复发生的动作。since从句的时态通常是一般过去时，主句中的时态则通常是现在完成时或现在完成进行时。
He has written to me frequently since I got sick.
自从我病了以后，他经常给我写信。
幻灯片9
(4)在It is＋时间段＋since从句句型中，时间的计算一律从since从句的动作完成或状态结束时算起。
It is half a year since she was in our class.
她离开我们班有半年了。
It is three years since he smoked.他戒烟有三年了。
二、条件状语从句
1．if和unless
(1)if意为“如果”，而unless意为“除非，如果不”。if...not与unless通常可互换，但if可引导非真实条件句(用虚拟语气)，unless一般不表示非真实条件。
幻灯片10
(2)if引导的从句表示好的条件时，可用providing that，provided that，on condition that 等替换；表示不好的条件时，可用so(as)long as替换。
If I were you，I would go to university for further education.
我要是你，我会上大学接受更进一步的教育。
They have a meeting every Monday，unless there is nothing to discuss.他们每周一开一次会，除非没有事情可商谈。
幻灯片11
2．supposing (假如)，suppose (that)(假如)，as (so) long as (只要)，on condition that (在……条件下)，等引导从句，表示“如果，只要，在……条件下”等意义。in case引导从句，表示“万一……”。
Supposing you are wrong，what will you do?
假定你是错的，你怎么办？
You can go out，as long as you promise to be back before 11 o’clock.只要你答应十一点钟前回来，你就可以出去。

3．only if引导从句用陈述语气，意为“只要……”；if only引导从句用虚拟语气，意为“但愿……，要是……就好了”。
Only if we persist in carrying out the open-door policy，we will achieve greater success.
只要我们坚持实行开放政策，我们就会取得更大的成就。

要是我早知道那件事，我就不会麻烦他了。
幻灯片13
4．祈使句＋and/or ＋句子，祈使句表示条件。
Give him an inch and he will take a mile.得寸进尺。
三、让步状语从句
1．though ，although ，even if ，even though
都有“虽然，即使，尽管”的意思，even if ，even though 语气较强，though 和although 语气较弱。though 不如although 正式；though 可用于假设，although 用于陈述“事实”。 I had a good time although/though/even if/even though I didn ’t know anybody at the party.
尽管在聚会上我谁也不认识，但我还是玩得很高兴。
幻灯片14
注意：(1)though ，although 等不与but 连用，但可在主句前加yet ，still 。
(2)though 从句中形容词、名词等为表语时，为加强语气可置于though 前。
2．while 也可引导让步从句，突出对比主句和从句所表示的两种情况。
While he is young ，he is experienced.
他虽然年轻，却有经验。
幻灯片15
3．whether...or (not)可引导让步状语从句，提供两个对比的情况，意为“不管……”。 Whether it rains or not ，I shall go out tomorrow.
不管下不下雨，明天我要出去。
4．whatever ，whenever ，wherever ，whoever ，whichever ，however 也可以引导让步状语从句，相当于no matter what (when ，where ，who ，which ，how)，意思为：无论什么，无论何时，无论何处，无论是谁，无论哪一个，无论如何。however 引导让步状语从句时与它所修饰的词在从句的句首。
幻灯片16
Whatever happens ，we shall never lose heart.(＝No matter what happens ，we shall never lose heart.)
无论发生什么，我们都不会失去信心。
5．as 引导的让步状语从句必须倒装，结构如下：

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.
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。
初中英语状语从句知识点总结（一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。 如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。

（adverbial clause of time） 概念：在复合句中，由时间连接词引导的状语从句叫做时间状语从句。(在复合句中，要注意主句和从句的时态大多都要保持一致。） 1.由when, while, as，after,before,since,untill,引导的时间状语从句。例如： When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。 When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！ Strike while the iron is hot. 趁热打铁。 You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。 Our headmaster laughed as she spoke.我们的校长边谈边笑。 主要时态：主过从过；主将从现；主句为一般现在时，从句不受影响。 编辑本段when, while和as的区别 when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。并且when 有时表示“就在那时”。例如： When she came in, I stopped eating.她进来时，我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当我住在农村时，我常常为他担水。（延续性的动词） We were about to leave when he came in.我们就要离开，就在那时他进来了。 While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如： While my wife was reading the newspaper, I was watching TV. (was reading 是延续性的动词，was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比） As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。例如： We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）As we was going out, it began to snow.当我们出门时，开始下雪了。（as 强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间） 2.由before和after引导的时间状语从句。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 引导的主句谓语用的是过去完成时，则从句动词多用一般过去时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. 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. The moment he saw me, he ran away. 他一看见我，就跑了。 He said he’d call you the moment he got home. 他说他一到家就给你打电话 （3）The instant I saw him, I knew he was the man from the restaurant. （4）Immediately you begin to speak, he gives you his full attention.你只要一开始说话，他就全神贯注地听。 （5）My sister came directly she got my message. 我妹妹一收到我的信息就来了。 （6）Every time I listen to your advice, I get into trouble. （7）no sooner... than... ，"一...就..." ，引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. （8）He had hardly sat down when the telephone rang.他刚坐下电话就响了。 He had scarcely sat down when there was a knock at the door. 他刚坐下就有人敲门 另外，如果把hardly放于句首，主句要用倒装结构。如： Hardly had I finished eating when he came in. 我刚吃完他就进来了。 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. 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
状语从句 状语从句在句中作状语，修饰主句中的动词、形容词或副词等。状语从句放在主句之前时，常用逗号分开;放在主句之后，一般不用逗号。状语从句按其意义和作用可分为时间、原因、地点、条件、让步、目的、结果、方式、比较等9种。 1.时间状语从句 时间状语从句表示主句动作发生的时间，主要由when，while，as ; before, after; till (until); once, by the time, as soon as, no sooner ... than和hardly ... when及名词词组the moment等引导。 1) when“在……的时候”; while “在……期间”; as “正当……的时候” when意为“在……的时候”，强调“特定时间”。 When spring came, he felt like a trip. When he was eating his breakfast, he heard the doorbell ring. 说明：连词when在状语从句中还有如下几种含义： ①表示突然发生的事，含义为“（正在……时）忽然”。 I was just coming along to see you when I ran into Wilson. I had been working a couple of months when I had a letter from Jane. ②表示过早发生某事，意为“（还没……）就”。此含义有时可用before代替。 I hadn’t been reading for half an hour when I heard steps outside. 我刚读了不到半个小时就听到外面有脚步声。 I had been there little more than a week when I set to work in earnest. ③表示“在……的情况下”，常可译为“虽然”，“既然”，“如果”。 She refuses help when (although) she has many friends. Why do you walk when (since) you have a car? How can I help them to understand when (if) they won’t liste n to me. ④后接虚拟结构，含义为“本可以，应该……”。 He stopped trying when he might have succeeded next time. They were playing when they could have been working. while意为“在……期间”，从句用持续性动词，表时间的一段，而不是一点。 While he was eating his breakfast, he heard the doorbell ring. We must strike while the iron is hot. 说明：连词while在状语从句中还有如下几种含义： ①意为“然而，但是”，表示前后对照，说明两种情况相反 Tom is very outgoing, while Jane is shy and quiet. Some people waste food while others haven’t enough.
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.
