篇1：中考语法知识：状语从句
状语从句
状语从句不仅是初中英语学习的重点，而且也是每年中考必考的内容之一。从笔者研读历年全国各地中考英语试题对状语从句的考查内容来看，命题主要集中在引导状语从句的连词、状语从句的时态等方面；从九大状语从句来看，同学们应将复习重点放在时间状语从句、条件状语从句、结果状语从句和比较状语从句这四种上。
核心知识
一、对时间状语从句的考查
1．要点：
1）引导时间状语从句的连词有：while， when，as，as soon as，until，not．．．until，before， after，since，etc．要掌握每个连词的含义及其用法，还有它们之间的一些区别。
2）when，while，as的区别：
①三者均可表示“当……的时候”，如果主句表示的是短暂的动作，而从句表示的是一段时间，三者可通用。如：
I met Kang Li as／when／while I was walking along the street．当我沿街散步时碰见了康丽。
②as和when都可与终止性动词连用， while只能与延续性动词连用。如：
It was snowing when we got to the airport．当我们到达机场时，天正下着雪。（不能用 while）
③as强调主句与从句表示的动作同时发生；while强调主句表示的动作持续于while所指的整个时间内；when可指主、从句所述动作同时或先后发生。如：
He sang as he went along．他边走边唱。
Please write while I read．我读的时候，请写下来。
When he reached home，he had a little rest．回到家后，他休息了一会儿。
3）until和till在肯定句中表示“直到……为止”，主句要用延续性动词；在否定句中，表示“直到……才”，主句常用终止性动词，这时till和until可用before替换。如：
I waited till／until he arrived．我一直等到他到来。
We won't start until／till／before Bob comes．鲍勃到来之前，我们不会动身。
4）since从句中常用过去时，主句用一般现在时或现在完成时；如果主句是一般将来时，情态动词加动词原形或祈使句时，时间状语从句用一般现在时。如：
Where have you been since I saw you last？上次我和你见面之后，你到哪里去了？
I'll phone you as soon as I arrive in Tonghua．我一到通化就给你打电话。
2．考例：（所有考例取自、全国各省市中考英语试题）
1）我一到美国就给你打电话。（北京市海淀区）
I'll ring you up ______ soon ______ I get to America．
2）昨天直到雨停了，孩子们才离开学校。（同上）
The children ______ leave school ______ the rain stopped yesterday．
3）It ______ ten years since they ______ to France．（河北）
A．as；covered
B．was；have moved
C．is；have moved
D．is；moved
4）He ______ wait until the rain ______ ．（南京市）
A．won't；will stop
B．won't；stop
C．will；stops
D．will；will stop
二、对条件状语从句的考查
1．要点：引导条件状语从句的连词有if（如果）、unless（除非）等，unless在意义上相当于if．．．not。条件状语从句也像时间状语从句一样，如果主句用将来时，从句要用现在时代替将来时。如：
You will fail unless you study hard．（＝You will fail if you don't study hard．）除非你努力学习，否则你会失败。
2．考例：
1）He will go to the Great Wall if it ______ tomorrow．（北京市宣武区）
A．won't rain
B．doesn't rain
C．don't rain
D．isn't raining
2） ______ you eat old food，you may be ill．（湖南）
A．Before
B．Why
C．If
D．Which
三、对比较状语从句的考查
1．要点：引导比较状语从句的连词有as．．．as，than。
1）表示甲与乙在某一方面相同时，用“as＋原级＋as”句型；表示甲在某一方面不如乙时，用“not as ／so ＋原级＋as”句型。如：
Dalian is as beautiful as Shenzhen．大连和深圳一样的美。
I don't run as／so fast as Kang Li．我不如康丽跑得快。
2）表示甲超过或不及乙时，用“比较级＋从句”（从句中常省略意义与主句相同的部分）。如：
He runs faster than you（do）．他跑得比你快。
Today is less cold than yesterday．今天没有昨天冷。
2．考例：
1）Jack runs as ______ as Tom．（北京市宣武区）
A．fast
B．faster
C．fastest
D．much faster
2）30，000dollars is a large amount of money，but it's ______ than we need．（上海市）
A．for more
B．very much
C．far less
D．very little
四、对结果状语从句的考查
1．要点：引导结果状语从句的连词有so．．．that（如此……以致于），such．．．that（如此……以致于）等。常用句型：
so＋形容词／副词＋that从句
such a／an ＋形容词＋单数可数名词＋ that从句
such＋形容词＋复数可数名词／不可数名词＋that从句
so＋形容词＋a／an＋单数可数名词＋that从句
He spoke so fast that I couldn't follow him．他讲得太快，我跟不上。
He told us such funny stories that we all laughed．
他给我们讲了那么多有趣的故事，我们全都哈哈大笑。
2．考例：

This mountain is ______ ______ that we can ______ ______ the top．
2）Miss Gao asked a question，but it was ______ that nobody could answer it．
A．very difficult
B．too difficult
C．difficult enough
D．so difficult
五、对其它状语从句的考查
还有五种状语从句：地点状语从句、原因状语从句、目的状语从句、方式状语从句、让步状语从句。
1．要点：
1）掌握常用的引导词：
① 引导地点状语从句的有：where（在哪里），wherever（无论何地），etc．如：
Where there is a will，there is a way．有志者，事竞成。
Wherever you go，I go too．无论你去哪里，我都去。
②引导原因状语从句的有because，as， since（因为），etc。because常回答why引导的疑问句，该从句一般位于主句后；since比as正式，两者不回答why引导的问句，而且其从句一般放在句首。如：
-Why can't I go？为什么我不能去？
-Because you're too young．因为你年纪太小了。
As（Since）you are not feeling well，you'd better stay at home．
既然你不太舒服，还是留在家里的好。
③引导目的状语从句的有so that（以便）等。如：
I packed him a little food so that he wouldn't be hungry．
我给他包了一点食物，让他不致挨饿。
④引导方式状语从句的有as（按照）等。如：
I will do it as you tell me．我将照你说的做。
⑤引导让步状语从句的有though／although（虽然），even though（尽管），whoever／ no matter who（无论谁），however／no matter how（无论怎样），whatever／no matter what（无论什么）等。如：
Though it's hard work，I enjoy it．尽管这工作很辛苦，我还是很喜欢。
No matter how hard the work was，he never gave it up．不管工作多么艰难，他都从不放弃。
2）because不能与并列连词so，though ／although不能与but同时在句中使用。如：
She was late for school because she missed the bus．
｛
She missed the bus，so she was late for school．
It's not cheap，but it's very good．
｛
Though it's not cheap，it's very good．
2．考例：
1）I can't understand this passage _____ there are no new words in it．（安徽）
A．if
B．because
C．though
D．and
2）“Why did Li Lei use a pencil？”“ _____ his pen was broken．”（福州市）
A．Because
B．When
C．Until
D．If
六、对状语从句和宾语从句、简单句、并列句的混合考查
【考点1】区分when，if引导宾语从句和状语从句的不同：when引导时间状语从句意为“当……时候”，引导宾语从句意为“什么时候”；if引导条件状语从句意为“如果”，引导宾语从句意为“是否”。如：
1．-Mike wants to know if _____ a picnic tomorrow．
-Yes．But if it _____ ，we'll visit the museum instead．（河北）
A．you have；will rain
B．you will have；will rain
C．you will have；rains

-Sorry，I don't．When he _____ back， I'll tell you．（安徽）
A．comes；comes
B．comes；will come
C．will come；comes
D．will come；will come
【考点2】状语从句和宾语从句、状语从句和简单句、并列句的同义转换。如：
1．A：He is too young to go to school．
B：He is _____ young _____ he can't go to school．（四川）
2．A：Tom is the tallest in his class．
B：Tom is _____ _____ any other student in his class．（四川）

篇2：中考英语语法详解十四：状语从句
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。)
篇3：高考英语状语从句语法知识点与学习方法
一、时间状语从句
1、when的用法
(1)when既可引导一个持续性动作，也可引导一个短暂性动作，可用于表示主句和从句动作同时发生或从句动作先于主句动作，有时还可表示从句动作后于主句，意为“当。。。时候”。

三、原因状语从句
引导词：because, since,as, now that, not that…, but that…, seeing that, considering that, in that
注意：for也可以表示原因，属并列连词，但不是说明直接原因，而是对某种情况加以推断，用于表示补充说明理由。
四、目的状语从句

七、方式状语从句
引导词：as(像。。。一样，正如。。。)，as if/as though(好像，宛如)
注意：1、固定句型A is to B what C is to D.意为“A对B而言正如C对D一样”。

(3)某些短语也引导让步的从句或短语，意为“尽管”，如：in spite of the fact that, despite the fact that, regardless of(the fact that)
九、比较状语从句
引导词：as...as(和。。。一样)，not as/so...as(和。。。不一样)，than(比)，the more...the more...(越。。。越。。。)
十、状语从句中的省略问题
1、在状语从句中如果主语与主句的主语一致，同时从句中又含有系动词be，则通常可省去从句的主语和系动词be,留下其余部分。
2、若状语从句中主语是it, 动词是系动词be, 则通常可省去主语it及系动词be,留下其余部分。
英语学习方法有哪些?
听、说、读、写是学习英语的正确顺序，但在传统英语教学中，听和说往往被忽视，课堂上注重的是应试能力，但这并不提倡。那么，英语学习方法有哪些呢?
听力：
英语听力的提升是需要适应的一个过程，需要长期坚持，要持续不要断续。对于听力的练习途径当然是录音，除了老师会在学校教室里放，自己也要经常去听，要坚持听，只有听多了才能知根知底，最好是一遍听，一遍写下来，可以从刚开始的听一两句，写一两句，到后面逐渐增加，这是一种看得见的实质提升。
单词：
一篇文章能不能看懂，关键在于你的词汇量掌握多少，如果词汇量多，那么不说能完全看懂文章，但是知道个大概是完全没有问题的，所以我们想要学英语，那么就必须要记住更多的单词。
语法：
语法的重要性相信是不必多说的，我们的同学最好是有一个语法总结本，可以在里面记录其语法，语法本身就是英语的核心，想要学好英语，那么会语法是必须的，同学们可以尝试着用背诵来理解语法，对于一些语法如果记不住，那么就记忆一些关键的语法句子，这样会让你的英语学习事半功倍。

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。)
He looks as if (as though) he had been hit by lighting.
他那样子就像被雷击了似的。(与事实相反，谓语用虚拟语气。)
It looks as if the weather may pick up very soon.
看来天气很快就会好起来。(实现的可能性较大，谓语用陈述语气。)
说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如：
He stared at me as if seeing me for first time.
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.
波涛冲击着岩石，好像很愤怒。
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
篇5：语法复习六：状语从句
由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。同时对方式状语从句也应引起重视。
（一）时间状语从句
表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。
e.g. When I came into the office, the teachers were having a meeting.
He started as soon as he received the news.
Once you see him, you will never forget him.
No sooner had I gone to bed than I went to sleep.
（二）原因状语从句
原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because强。
e.g. He is disappointed because he didn't get the position.
As it is raining, I will not go out.
Now that you mention it, I do remember.
（三）地点状语从句
引导地点状语从句的连词是where 和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
（四）目的状语从句
引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。
e.g. Speak clearly, so that they may understand you.
She has bought the book in order that she could follow the TV lessons.
He left early in case he should miss the train.
（五）结果状语从句
结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that （从句谓语一般没有情态动词）, so … that, such … that等引导。
e.g. She was ill, so that she didn’t attend the meeting.
He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
（六）条件状语从句
条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：条件从句中的if 不能用whether替换。
e.g. If he is not in the office, he must be out for lunch.
You may borrow the book so long as you keep it clean.
So far as I know（据我所知）, he will be away for three months.
You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.
If he had come a few minutes earlier, he could have seen her.
（七）让步状语从句
让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引导。注意：as引导的让步状语从句一般是倒装的。
e.g. Though he is a child, he knows a lot.
Child as he is, he knows a lot.
Whatever ( = No matter what ) you say, I’ll never change my mind.
（八）方式状语从句
方式状语从句常由as, as if (though), the way, rather than等引导。
e.g. You must do the exercise as I show you.
He acted as if nothing had happened.
（九）比较状语从句
比较状语从句常用than, so (as) … as, the more … the more等引导。
e.g. I have made a lot more mistakes than you have.
He smokes cigarettes as expensive as he can afford.
The busier he is, the happier he feels.
（十）使用状语从句时要注意的几个问题
1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。
e.g. We’ll go outing if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shanghai.
2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be ，就可省略从句中的“主语 + be”部分。
e.g. When (he was) still a boy of ten, he had to work day and night.
If (you are) asked you may come in.
If (it is) necessary I’ll explain to you again.
3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。
e.g. You are to find it where you left it.（地点状语从句）
Tell me the address where he lives.（定语从句，句中有先行词）
I don’t know where he came from.（宾语从句）
Where he has gone is not known yet.（主语从句）
This place is where they once hid.（表语从句）
