(完整)高中英语状语从句讲解及练习
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
D. hurriedly

5. ______ the day went on, the weather got worse.
１

B. Since
C. While

(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.
A. so that

Eg: If it snows tomorrow, the flight will be canceled.
If I were a bird, I would fly.
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.
Ex

--I’ll probably go for a walk later on ___ it stays fine.

（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)

2. as–不谈自明的原因，语气最弱。
Eg:As he is honest and modest, all his friends like him.
3. for–放句中，对前面一句话的内容的补充说明。Fot引导的原因状语从句只能置于主句之后并且必须用逗号将其与主句隔开。
Eg: He could not have seen me, for I was not there.
4. since/ seeing (that)/ now (that)/ considering (that)/ in that –通常放句首．译为“既然”。

I get up early so that I should catch the train.我早起的目的是搭到火车。
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”

(完整word版)高中英语状语从句用法详细解析
高中英语状语从句用法详细解析 一、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。 二、分类 根据意义上的不同，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句 三、时间状语从句 （一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once. （二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。

When (While) we were at school, we went to the library every day. While表示时间段,因此，while 从句的谓语动词要用延续性动词。如： Please don't talk so loud while others are working. As与when用法相似，但着重强调主句动作与从句动作同时发生，有"随着……"或"一边……一边……"之意。如： As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。 2．Because,as,since 的区别： Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如： Water is very important because we can't live without it. He didn't come yesterday as his mother was ill. I'll do it for you since you are busy.
状语从句用法讲解和练习
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：
