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。

2011届高考英语一轮复习讲解：状语从句【知识要点】定义：用来充当状语的句子称为状语从句。
功能：它主要用于修饰句子中的谓语动词、形容词或副词等，有时修饰整个句子。
位置：状语从句的位置较活：可以放在主句之前，用逗号与主句隔开；也可以放在主句之后，一般不用逗号。
由于它是从各个方面来修饰、说明谓语动词发生时的各种情况，所以常见的状语从句有九种之多。
各种不同的状语从句所使用的关系词也各不相同。
一、时间状语从句引导时间状语从句的从属连词有很多，现将分类用法如下：1.从属连词when，while与as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 somesth.when...某人刚干了某事就在这时……2)when还表示原因“既然”。
如：It was foolish of you to take a taxi when you could easily walk here in five minutes.既然你可以步行五分钟就能到这儿，坐出租车来真是愚蠢。
3)while作为并列连词，意为“而，却”，表示对比。
He likes pop music，while I am fond of folk music.他喜欢流行音乐，而我却喜欢民间音乐。
4)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.我在街道上走的时候，见到了我的一个老朋友。
2.从属连词：as soon as，immediately，directly，the moment，the minute，no sooner...than...,hardly/scarcely... when...，once这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，意为“一……就……”。
从句中用一般时态代替将来时态。
如：Once you remember it，you’ll never forget it.一旦你记住它，就永远不会忘记。
The moment I heard the voice，I knew father was coming.我一听到声音，就知道是父亲来了。
No sooner had we arrived at the station than the train left.我们一到达车站，车就 开了 。
注：no sooner...than...; hardly/scarcely...when...这一结构的时态搭配：no sooner与hardly/scarcely引导的主句谓语动词应用过去完成时，而than与when的从句中谓语应用一般过去时。
此外，当把no sooner和hardly/scarcely提到句首时，应用倒装语序。
我一到家，天就开始下雨了。
I had hardly got home when it began to rain.→Hardly had I got home when it began to rain.3.till，until (not...until/till...直到……才)注：1) till不可以置于句首，而until可以置于句首。
如：Until you told me I had no idea of it.直到你告诉我，我对此事才有所了解。
2)如果将“not until...”结构放在句首，那么主句要写成倒装句。
如：Not until we pointed out their fault to them did they realize it.直到我们向他们指出了他们的错误，他们才意识到。
4.every time，each time，next time等名词短语用来引导时间状语从句，表示“每当……，每次……，下次……”。
如：Every/Each time I was in trouble，he would come to help me out.每次我遇到麻烦，他总会来帮我。
Next time you come，do remember to bring your son here.下次你来的时候，一定要记得把你儿子带来。
5.从属连词：before(在……之前)，after(在……之后)，since(自从……以来)。
如：Please remember to turn off all the lights before you leave the classroom.离开教室前，请记得把所有的灯都关上。
注：1)上述三个连词，既是从属连词，也是介词。
2)若表达“还未……就……”“不到……就……”“……才……”“趁……，还没来得及”时，需用连词before。
如：We had sailed four days and four nights before we saw land.我们航行了四天四夜才看到陆地。
We hadn’t run a mil e before he felt tired.我们跑了还不到一英里他就累了。
Please write it down before you forget it.趁你现在没忘把它记下来。
二、地点状语从句1.常用的引导词有where（在……地方）,wherever（无论在什么地方）等。
指具体地点时，从句可用于主句之前或之后，表示抽象条件时，从句须放在主句之前。
如：The university graduates are determined to go wherever they are needed most.那些大学毕业生们决心去最需要他们的地方。
They are planting trees where there is plenty of water and sunlight.他们在阳光雨水充分的地方植树。
Where there is a will,there is a way.有志者事竟成。
2.注意区分where引导的定语从句与状语从句。
你最好在有问题的地方作个标记。
You’d better make a mark where you have any q uestions.(状语从句)You’d better make a mark at the place where you have any questions.(定语从句)三、条件状语从句1.常用的引导词有if（如果，假如）,unless（除非，要不……就不）,as long as（只要）,so long as（只要）,provided (that）（只要），suppose/supposing（假设），on condition (that）（如果）等。
如：I may not come to see you recently unless I can complete the project ahead of time.除非我能提前完成那个项目，否则我最近不会来看你了。
We can surely attain our goal as long as we are united as one.只要我们团结一致，我们肯定能实现我们的目标。
What shall we do if we can not get the necessary data？如果我们弄不到必要的数据，我们怎么办？They promised to let us have a meeting in their office on condition(that）we could keep it clean.如果我们能保持清洁，他们答应让我们在他们的办公室里开会。
2.要点提示：1)在表示条件的状语从句中，既可以用直陈语气作“真实条件句”，也可以用虚拟语气作“非真实条件句”。
至于把句子作成哪一种条件句，要依照“有关语法规则”和“表达意思的需要”而定。
2)用unless引导条件状语从句时，要注意这个连词自身在意义上是否定的：unless=if...not...。
因此，我们在逻辑上要注意：英文句子的用法和中文句子的译文。
特别是当主句是否定句时，逻辑上的意思就成了“否定之否定而表示肯定”的情况了。
如：I will not go to their party unless I am invited.这个句子的实际意义等于：I will not go to their party if I am not invited.这就是说，“我不去参加聚会”的条件是“我没有受到邀请”。
“不去”与“没有受到邀请”就构成了“否定之否定而表示肯定”的情况了。
）假如他们不邀请我，我不会去参加他们的聚会。
He will finish the work in time unless something unexpected happens.这个句子的实际意义等于：He will finish the work in time if something unexpected does not happen.假如没有什么意外的事情发生，他会按时完成他的工作的。
3)suppose/supposing这两个词所表达的意义和句法功能是一样的。
它们与其他的引导状语从句的从属连词一样，引导一个含状语从句的主从复合句。
而它们的特别之处在于：有时由它们所引出的条件状语从句常与主句分开而独立成句，但其意义和作用还是条件状语从句。
这种情况多数出现在科技文章及某些论文里。
如：Suppose no more rain fell into the Atlantic Ocean and no more water was brought to it by rivers.It would take the ocean about 4000 years to dry up.假如不再有雨水注入大西洋，不再有河水流入大西洋的话；大约需要四千年的时间大西洋才会枯竭。
Suppose your statement is right.How are you going to prove it?假定为你的观点是正确的，你打算如何证明这一点呢？Suppose this poor girl is yours.We’d like to know how much you know about her.假设这个可怜的女孩就是你的；我们想了解你知道多少关于她的情况。
