状语从句的分类
一、时间状语从句
时间状语从句表示时间，引导词有：when, while, as, till, until before, after, since等。
时间状语从句的引导词所表示的意思不尽相同，要注意把握不同引导词所表示的不同时间关系，以及它在具体句子中对应的时态、语态等问题。
注意：as(在……时候，因为)，since(自从，因为)，它们可以引导时间从句，并强调主句和从句的动作同事发生。并且while有时还可以表示对比。例如：
(1)While my mother was reading the newspaper, I was watching TV.(read是延续性的动词，read和watch同事发生)
I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。(对比)
(2)when(当……的时候)，引导的从句的谓语动词可以是延续性动词，也可以是瞬间动词。从句动作可与主语动作同事发生，也可在其后发生。
I was reading a book when she came into my room.(come是瞬间动词，只能用when引导，不能用while)
I often missed my home when(while) I lived in NewYork.(live是延续性动词，when可用while代替)
(3)when和while的区别还在于：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While they were talking, the bell rang.正在他们谈话的时候，上课铃响了。
(4)as译作 “一边……一边”、“随着……”，侧重主句和从句的动作同时发生。有时可与when，while通用。
We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”)
As you grow, you will know more and more。随着年龄的增长，你会懂得越来越多。
2.till或until引导的时间状语从句
till，until(直到……才)：一般情况下两者可以互换，但是在强调句型中多用until。till不可以在句首，而until可以放在句首。
注意：如果主句中的的谓语动词是瞬间动词时，必须用否定形式;如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。例如：
I didn’t go to bed until(till) my father came back.直到我父亲回来我才上床睡觉。(go to bed 是瞬间动词，主句用否定形式)
I talked until he came back.我工作到他回来为止
I didn't work until he came back.他回来我这才开始工作
Please wait until I arrived.在我到达之前等我。
3.since引导的时间状语从句
Since(自从)：引导的从句的谓语动词可以是延续性的动词，也可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动作用现在完成时。但在It is+时间+since从句的句型中，主句多用一般现在时。例如：
I have been in Beijing since you left. 自从你离开以来，我一直在北京。
Where have you been since I last saw you? 自上次我和你见面以后，你到哪里去了?
It is five months since our boss was in Beijing. 我们老板离开北京有五个月了。
4.由before和after引导的时间状语从句
注意：(1)before(在……之前)：引导的从句不再用否定的谓语。
(2)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。
(3)after(在……之后)：表示主句动作发生在从句动作之后。如果主句用的是过去时，则从句多用过去完成时。例如：
It will be four days before they come back. 他们要过四天才能回来
My father had left for Canada just before the letter arrived. 我父亲恰好在信到之前去加拿大了。
After we had finished the work, we went home. 完成工作之后，我们回家了(从句用过去完成时，主句用一般过去时)
5.由as soon as ,immediately, directly ,instantly, the moment, the instant, the minute,等引导的时间状语从句：这些连词都表示“一……就”。例如：
I will go there directly I have finished my breakfast.吃完早饭，我立即到那里去。
The moment I heard the news, I went to the school. 我一听到消息，马上赶到了学校。
As soon as I reach Canada, I will ring you up.我一到加拿大，就给你来电话。
注意 hardly(scarcely，rarely)……when,before，no sooner …than相当于 as soon as之意。主句用过去完成时，从句用一般过去时态。当hardly，scarcely, rarely和 no sooner位于句首时，主句应用倒装语序。例如：
Hardly had I sat down when he stepped in ,我刚坐下，他就进来了。
二、原因状语从句
原因状语从句表原因，常见的引导词有：because(因为)，since(既然)，as(既然)，for(因为)
1.becausey引导的原因状语从句一般放于主句之后，because表示直接原因，语气最强，回答why引导的疑问句必须使用because。
I do it because I like it
——Why didn’t he come yesterday?
——Because he had something important to do.
注意 “not……because” 结构中的not否定的是because引导的整个从句，例如：The country is not strong because it is large.国强不在大。
2.Since引导的原因状语从句一般位于主句之前，表示已知的、显然的理由。通常被翻译成“既然”，较为正式，语气比because弱……
Since you are free today, you had better help me with my mathematics,既然今天你休息，你最好帮我补习数学。
3.as引导原因状语从句时表示附带说明的“双方已知的原因”，语气比since弱，较正式，位置较灵活，常放于主句之前。
As it is raining, you’d better take a taxi，既然在下雨，你最好乘出租汽车。
4. for引导的原因状语从句并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，for引导的原因状语从句只能放于主句之后并且必须用逗号将其与主句隔开。
He could not have seen me, for I was not there.他不可能见过我，因为我不在那里。
三、条件状语从句
引导条件句常用的连词有if(如果)，unless(如果不，除非)等，条件状语从句和时间状语从句一样，表示将来要用一般现在时态。
We won’t let you in unless you show your pass.
If you fail again this time,what will you do?
(1)if引导的条件状语从句表示将来时，要用一般现在时代替，主句仍使用一般将来时态。
(2)将if引导的宾语从句和状语从句进行混淆考查，宾语从句中的if表示“是否”，可以使用一般将来时。
四、让步状语从句
让步状语从句表示“虽然，即使，尽管”。引导词有although，though，even though, even if都表示“虽然，即使，尽管”之意。主句中不能用but，但可用yet、
Though和although语气较弱(其中的though比although通俗，不如although正式)，even if和even though带有强调意味而显得语气更强。例如：
Although they are poor ,they are happy yet.虽然他们很穷，但很快乐
The article is very important though it is short.那篇文章虽然很短，但很重要。
Even though it was raining, she walked to work.即使下雨，她也是走着去工作的。
I’ll visit him this evening even if I can stay only a few minutes.今晚我将去拜访他，即使我只能停留一小会儿。
注意though引导的让步状语从句的用法比较特殊，它可以倒装，也可以不倒装。
五、地点状语从句
地点状语从句常由where和wherever引导，通常可置于主句之前或之后。
如：We should go where(ver) we are most needed,我们要去最需要我们的地方。
Where there is a will, there is a way.有志者，事竟成。
六、目的状语从句
目的状语从句通常由so that, in order that 引导，所引导的从句通常放在主句后面。目的状语从句中的谓语常含有may (might)，can (could)，shall ,will 等情态动词。
如：He always takes a seat in the first row so that/in order that he can hear better.
= In order that he can hear better, he always takes a seat in the first row.为了听得更清楚，他总是坐前排的座位。
七、结果状语从句
结果状语从句常由so that, so…that, such…that等引导，放在主句之后，so…that与such…that句型在一定条件下可转换。
如：He made such an excellent speech that everyone admired him.
= He made so excellent a speech that everyone admired him.
他的演讲如此精彩以至于每个人都很钦佩他。
注意 so that 引导结果状语从句和目的状语从句的辨别
so that从句之前有个逗号的常为结果状语从句，因表示某一行为带来的结果，从句中的时态常为过去式;
so that从句中有may(might)，can(could)，should, will等情态动词的通常是目的状语从句。
如：I wrote as clearly as possible, so that I got high marks.(目的)我尽可能地写清楚些，这样可以得高分。
He went to the lecture early so that he could get a good seat.(目的)他很早就去听报告了，以便可以找到一个好座位。
He went to the lecture early, so that he got a good seat.(结果)他很早就去听报告了，这样他就找到一个好座位。
八、比较状语从句
1.比较状语从句常由as…as，not so(as)，than引导。比较从句部分常为省略句。
如：His brother is as handsome as he (is)/him.(非正式英语中可用宾格him)他弟弟和他一样英俊。
He swims faster than any other student in his class(does)。他比班上其他任何人都游得快。
2.通常把the more…the more…结构也归为比较从句，意为：“越…越”。
如：The harder you work, the greater progress you’ll make.你越努力学习，就会取得越大的进步。
The less she worried, the better she worked.她担心得越少，就工作得越好。
九、方式状语从句
1.方式状语从句常由(just)as(像…)，as if/though(好像)引导，表示动作的方式。
如：Do exactly as the doctor says.一定要按照大夫的话去做。
He walked slowly as if/though he had hurt his leg.他慢慢地走着，仿佛是腿受了伤。
注：在非正式问题中有时会用like代替as引导方式从句。
2.as if/though引导的状语从句，若描述非事实情况，常用虚拟语气，若描述的是实际情况，用陈述语气。
如：She treats the orphan as if/though he was her own child.她对待孤儿就像是她自己的孩子一样。(他是孤儿，当然就不是她亲生孩子，故用虚拟语气。)
It looks as if/though it’s going to rain.看起来天像是要下雨了。(本句用的是陈述语气，说明天真象是要下雨了。)
1状语从句
在复合句中，修饰主句中的动词、形容词或副词等的从句叫状语从句。状语从句根据它表达的意思可分为时间、地点、原因、目的、结果、让步、比较(或方式)和条件等类。

I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2)由because引导的从句如果放在句末，且前面有逗 号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。

5.结果状语从句
引导连词有that，so…that…，such….that

例句(1)可以改写成：She is so good a teacher that we all love her.
2.在such+形容词+名词复数或不可数名词+that…结构中，形容词如果是many/few或much/little时，用so不用such，即：so+many/few+可数名词复数+that…，so+much/little+不可数名词+that…

2) 原因状语从句because与because of ;
Because+从句和because of +n./ pron
例如：

总是站在系统的高度把握知识
很多同学在学习中习惯于跟着老师一节一节的走，一章一章的学，不太对意章节与学科整体系统之间的关系，只见树木，不见森林。随着时间推移，所学知识不断增加，就会感到内容繁杂、头绪不清，记忆负担加重。事实上，任何一门学科都有自身的知识结构系统，学习一门学科前最先应了解这一系统，从整体上把握知识，学习每一部分内容都要弄清其在整体系统中的位置，这样做往往使所学知识更容易把握。
追根溯源，寻求事物之间的内在联系
学习最忌死记硬背，特别是理科学习，更重要的是弄清楚道理，所以不论学习什么内容，都要问为什么，这样学到的知识似有源上水，有木之本。即使你所提的问题超出了中学知识范围，甚至老师也回答不出来，但这并不要紧，要紧的是对什么事都要有求知欲，好奇心，这往往是培养我们学习兴趣的重要途径，更重要的是养成这种思考习惯，有利于思维品质的训练。
发散思维，养成联想的思维习惯
在学习中我们应经常注意新旧知识之间、学科之间、所学内容与生活实际等方面的联系，不要孤立的对待知识，养成多角度地去思考问题的习惯，有意识地去训练思维的流畅性、灵活性及独创性，长期下去，必然会促进智力素质的发展。

地点状语从句通常由where, wherever 引导。

我住的地方树很多。
Wherever I am I will be thinking of you.
不管我在哪里我都会想到你。
2 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。)

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.

3 原因状语从句
比较：because, since, as和for
1) because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since。
I didn't go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2) 由because引导的从句如果放在句末，且前面有逗 号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
He is absent today, because / for he is ill.
He must be ill, for he is absent today.
4 目的状语从句
表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导，例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
5 结果状语从句
结果状语从句常由so… that 或 such…that引导，掌握这两个句型，首先要了解so 和 such与其后的词的搭配规律。
比较：so和 such
其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。 so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
( so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能用such搭配。)
so…that与such…that之间的转换既为 so与such之间的转换。
The boy is so young that he can't go to school.
He is such a young boy that he can't go to school
6 条件状语从句
连接词主要有 if, unless, as/so long as, on condition that 等。.
if 引导的条件句有真实条件句和非真实条件句两种。非真实条件句已在虚拟语气中阐述。
unless = if not.
Let's go out for a walk unless you are too tired.
If you are not too tied, let's go out for a walk.
典型例题
You will be late ___ you leave immediately.
A. unless B. until C. if D. or
答案A。 句意：除非你立即走，否则你就回迟到的。可转化为 If you dong leave immediately, you will be late. B、D句意不对，or表转折，句子如为 You leave immediately or you will be late.
7 让步状语从句
though, although
注意： 当有though, although时，后面的从句不能有but，但是 though 和yet可连用
Although it's raining, they are still working in the field.
虽然在下雨，但他们仍在地里干活。
He is very old, but he still works very hard.
虽然他很老，但仍然努力地工作。
Though the sore be healed, yet a scar may remain.
伤口虽愈合，但伤疤留下了。 (谚语)
典型例题
1) ___she is young, she knows quite a lot.
A. When B. However C. Although D. Unless
答案：C。意为虽然她很年轻，却知道许多。
2) as, though 引导的倒装句
as / though引导的让步从句必须表语或状语提前(形容词、副词、分词、实义动词提前)。
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意： a. 句首名词不能带任何冠词。
b. 句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
虽然他尽了努力，但他的工作总做的不尽人意。
3) ever if, even though. 即使
We'll make a trip even though the weather is bad.
4) whether…or- 不管……都
Whether you believe it or not, it is true.
5) “no matter +疑问词” 或“疑问词+后缀ever”
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意：no matter 不能引导主语从句和宾语从句。
(错)No matter what you say is of no use now.
(对)Whatever you say is of no use now.
你现在说什么也没用了。(Whatever you say是主语从句)
(错)Prisoners have to eat no matter what they're given,
(对)Prisoners have to eat whatever they're given. 囚犯们只能给什么吃什么。
8 比较while, when, as
1)as, when 引导短暂性动作的动词。
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。
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。
As the day went on, the weather got worse.
日子一天天过去，天气越变越坏。
9 比较until和till
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 until midnight. 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 Let's get in the wheat before the sun sets.)
否定句：
She didn't arrive until 6 o'clock.
她直到6点才到。
Don't get off the bus until it has stopped.
公共汽车停稳后再下车。
I didn't manage to do it until you had explained how. 直到你教我后，我才会做。
1)Until可用于句首，而till通常不用于句首。
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。
2)Until when 疑问句中，until要放在句首。
---Until when are you staying? 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。
(1)Not until …在句首，主句用倒装。
Not until the early years of the 19th century did man know what heat is.
直到19 世纪初，人类才知道热能是什么。
Not until I began to work did I realize how much time I had wasted.
直到我开始工作，我才认识到了我已蹉跎了几多岁月。
(2) It is not until… that…
10 表示“一…就…”的结构
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示“一…就…”的意思，例：
I had hardly / scarcely got home when it began to rain.
I had no sooner got home than it began to rain.
As soon as I got home, 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.
状语从句英语语法知识点汇总
考点聚焦
一、什么是宾语从句
在句中充当宾语的从句叫作宾语从句，宾语从句可作谓语动词的宾语，也可作介词的宾语。
二、宾语从句的引导词
1、that 无实意，用来引导陈述句的宾语从句，口语中常省略。例如：
She told me that she had been to Hong Kong twice.
她告诉我她去过香港两次。
I know(that)the visitors are from Australia.我知道这些游客来自澳大利亚。
2、if或whether这两个词是“是否”的意思，主要用来引导一般疑问句或选择问句的宾语从句，口语中多用if，不能省略。例如：
He asked me if / whether I had been to Beijing twice.
他问我是否去过北京两次。
She wanted to know whether I would go there or not.
她想知道我是否想去那里。
3、疑问词when ，where，who，how等，这类词通常引导特殊疑问句的宾语从句。例如：
Can you tell me how I can find Mr Wang?
你能告诉我怎样才能找到王先生吗?

三、宾语从句的语序
凡是从句都必须使用“主语在前，谓语在后”的陈述语序，宾语从句也不例外，也就是说宾语从句的语序必须是“引导词+主语+谓语+其它”。例如：
误：Could you tell me where is the bus station?
正：Could you tell me where the bus station is?
四、宾语从句的时态一致
1、当主句为一般现在时或一般将来时的时候，从句可以根据需要选择相应的时态，不受主句的影响;主句为一般过去时，从句要用相应的过去时态。例如：
I want to know what time he ate his breakfast.
我想知道他今天早晨几点钟吃早饭的。
They will tell us that they have been able to look after themselves.
他们将会告诉我们他们已经能照顾自己了。
I asked what my father was doing then.
我问那时我爸爸在干什么?
2、当宾语从句表述的是客观真理或自然现象是，宾语从句的时态不受主句的时态的影响，仍然用一般现在时。如：
He said the moon moves round the earth.
他说月亮围着地球转。
She asked whether light travels faster than sound.
她问光速是否比声速快。
五、宾语从句的简化
由特殊疑问词引导的宾语从句中的主语与主句的主语或宾语相同时常常可以将宾语从句简化成“特殊疑问词+动词不定式”这种结构。有时候由that引导的宾语从句也可以用动词不定式或者动词的ing形式来简化。如：
Can you tell me how I can get to the post office?
= Can you tell me how to get to the post office?
She don’t know whether she should go there with them or not.
= She don’t know whether to go there with them or not.
He can remember that he has climbed the tall tree.
= He can remember climbing the tall tree.
六、宾语从句的否定转移及其它
1、当I think/believe/guess等一些看法的词后面所接的宾语从句是否定句时，习惯上否定主句，采用“I don’t think/believe/guess+肯定形式的宾语从句”这种结构来表达。如：
我认为明天她不会来。
误：I think that she won’t come tomorrow.
正：I don’t think that she will come tomorrow.
2、对I think/believe/guess等动词后面所接的宾语从句进行划线部分提问时，要用“疑问词+do you think /believe/guess+宾语从句的剩余成分?”这种结构来表达。如：
你认为谁将在会上发言?
误：Do you think who will speak at the meeting?
正：Who do you think will speak at the meeting?
原因状语从句
比较：because， since， as和for
1)because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或 since.
I didn‘t go， because I was afraid.
Since /As the weather is so bad， we have to delay our journey.
2)由because引导的从句如果放在句末，且前面有逗
号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for.
He is absent today， because / for he is ill.
He must be ill， for he is absent today.
结果状语从句
结果状语从句常由so… that 或 such…that引导，掌握这两个句型，首先要了解so 和 such与其后的词的搭配规律。
比较：so和 such
其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。 so
还可与表示数量的形容词many， few， much， little连用，形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
( so many 已成固定搭配，a lot of 虽相当于 many，但 a lot of 为名词性的，只能用such搭配。)
so…that与such…that之间的转换既为 so与such之间的转换。
The boy is so young that he can‘t go to school.
He is such a young boy that he can‘t go to school
目的状语从句
表示目的状语的从句可以由that， so that， in order that， lest， for fear that， in
case等词引导，例如：
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better take more clothes in case the weather is cold.
一、1、在引导让步状语从句的从属连词中，比较常见的有although, though, even though, even if, whether…or…等。
2、另外，以-ever结尾的连词如however, whatever, whoever, whenever, wherever等也可引导让步状语从句，其用法相当于no matter…。
3、注意，while和when除用于引导时间状语从句外，有时也可引导让步状语从句，其意为“尽管”“虽然”。
二、除了上诉常见的从属连词引导让步状语从句外，as 也可以引导让步状语从句，但是，as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中，但although不可以这样用，例如：
引导让步状语从句时，as意为“虽然…但是”，“纵使…”之意”，“尽管”，通常从句要倒装，倒装的方法是将从句的表语或状语放在as之前，而用though引导让步状语从句时句字则不必倒装(口语中也可倒装).
1. Heavily as it was raining outside, they started out very early.
尽管外面下雨非常厉害，但是他们早早就开始了。
2. Young as he is, he knows a lot=Though he is young 或Young though he is, he….

5. Child as/though he was， he knew what was the right thing to do.(=Though he was a child，he knew what was the right thing to do.)

6. Fast as you read， you can’t finish the book so soon.
纵然你读得快，你也不能这么快读完这本书。
7. Lover of towns as I am， I realize that I owe a debt to my early country life.
尽管我爱城市，但我知道，以往的乡村生活使我受益匪浅。
8. Small as atome are， they are made up of still smaller units.
尽管原子很小，但它们由更小的单位构成。
