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。

A. immediately
B. shortly
C.quickly

(二)目的状语从句
1. (so) that/in order that
（so）that/in order that表示“为了，以便”，引导的目的状语从句要用虚拟语气。
Eg: He shouted at the top of his voice so that/in order that he might be heard.
如果表示“为了，以便”的目的状语从句的主语与主句的主语相同，可用in order to或so as to替代。Eg：I came early so as to/in order to catch the first train.
3.lest, for fear that, in case
lest, for fear that, in case表示“以免，以防”。其中lest, for fear that要用(should)+动词原形的虚拟语气；in case 后的从句可用虚拟语气，也可用陈述语气。
Eg：I will not make a noise lest/ for fear that I (should) disturb you.
Take your umbrella in case it rains.
Ex.
1. He whispered to his wife_______ he might wake up the sleeping baby.

2. in case, on condition that, provinding, provided (that), supposing, supposed (that) :“假如，在……条件下”Eg: The mother promises to the son to buy him a toy airplane on condition that he passes his English test. Suppose (that) he does not come, what shall we do?
3. unless:“除非”（=if not）
Eg: We can’t get there on time unless we book the ear liest flight
= We cannot get there on time if we don’t book the earliest flight.
4.as/so long as:“只要”
Eg: We will succeed as long as we keep on trying.

（四）让步状语从句
1. “虽然，即使，尽管”
a. although/ though/ even though/ even if
although/ though 语气较弱（尽管），even though/ even if（即使）语气较强。
although和though 可以互换，但though可以用于倒装也可以不倒装。（参见as引导让步状语从句的用法）Eg: Although/ though it was not his fault, he took all the blame.
Even if/ Even though you don’t like your boss, you should do your work.
b. as
as可引导让步状语从句，表示“虽然、尽管”，但要用倒装结构，形式如下：
1）. 形容词+ as + 主语+ 系动词。如：
Eg: Tired as he is, he offers to help me.
2）. 过去分词+ as + 主语+ 系动词。如：
Eg: Well-written as the book is, the author is not satisfied and prepared to revise it.
3）. 名词+ as + 主语+ 系动词。如：
Eg: Student as he is, he does not study hard.
4）. 副词+ as + 主语+ 谓语部分。如：
Eg: Much as I admire his courage, I don’t think he acted wisely.
２
5）. 动词原形+ as + 主语+ 谓语的另一部分（情态动词或助动词may, might, will,
would等）。如：
Eg: Try as you will, you won’t be able to persuade him.
注意：①若提前的表语是没有形容词修饰的单数可数名词，要省略不定代词。
②若提前的是动词原形，与之连用的情态动词要置于原来的位置，即主语之后。
③though在引导让步状语从句时可像as一样倒装。
2. while: 尽管
Eg: While it’s none of my business, I will watch you.
3.no matter (what, when, where): 无论（什么，何时，何地）
Eg: The old man wouldn’t believe anything no matter what you said.
Please tell me the result no matter when you get it.
4. however :不论怎样。however引导让步状语从句时，句子通常倒装，一般在however后加形容词或副词。Eg: The father couldn’t make his daughter smi le however hard he tried.
5. whether…or not: 不管是否
Eg: Whether he is good or not, the company decided to send him abroad.
总结：
1)although与though在一些情况下可互换，都可以与yet，still连用，但不能和but连用。
2)however引导让步状语从句时后紧跟形容词或副词。
3)while也可引导让步状语从句，这一点特容易被考生忽视。
4)whatever修饰名词，“无论什么”，however修饰形容词、副词，“无论多么，
无论怎么”。
5)even if/even though(即使)与as if/as though(好像)

Eg:As he is honest and modest, all his friends like him.

2. 表示“如此……以致……”的“so…that…”和“such…that…”均可以引导结果状语从句，其中的such 是形容词，修饰名词; so 是副词，修饰形容词或名词。具体搭配如下：
1）“so+adj./adv.+that”,“so+adj.(a/an)+n.+that”
2)“such(a/an)(+adj.)+n.+that”

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 1. 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。 I'll go on with the work when / come back tomorrow .我明天回来后会继续做我的工作。 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： 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

高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。

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 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：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. 【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。Until 是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。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.

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。
状语从句 在复合句中担任状语成分的从句称为状语从句，修饰主句的谓语动词，形容词或副词，状语 说白了就是修饰动作的词或句，也可以理解成修饰谓语的词或句。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） 状语的位置比较灵活，可以位于句首、句末或句中。enough 用作状语修饰形容词和副词时 必须后置。 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: 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 instant, immediately , directly, no sooner ? than, hardly ? when, scarcely ? when I didn ’ t realize how special my mother was until I became an adult. While John was watching TV , his wife was cooking. The children ran away from the orchard( 果园 ) the moment they saw the guard. No sooner had I arrived home than it began to rain. Every time I listen to your advice, I get into trouble. When , while, as 都可解释为“当```的时候”但侧重点有所不同。 1) When Eg: When I arrived home , I had a little rest. 注意点： when 从句的主语与主句主语相同，谓语动词是be 动词时，从句主语和be 可以省略。Eg: When (she was) walking along the street, she met her class teacher. 2) As As 除了表示“当```的时候”，还可表示为“一面``` 一面”，“随着” Eg: He sang as he danced.(一面 ```一面 ) You will grow wiser as you grow older.(随着) 3) While 表示“当 ``` 的时候” 强调主句的动作和从句的动作同时发生，从句一般用进行时， 从句动词必须是延续性动词。 Eg: While we were working, they were having a rest. While (they were) having a discussion, they got very confused. 注意点： while 有对比的含义，解释为“然而”。 eg: I prefer black tee, while he likes coffee. 1．until, not ? until 表示“直到 ```才” ,在肯定句中主句常用延续性动词；在否定句中主句常用短暂性动词。
