知识讲解
时间状语从句
一、普通从属连词
引导时间状语从句的普通类从属连词有when（当……时），while（在……期间），as（当……，一边……一边……），before（在……之前），after（在……之后），since（从……以来），till/until （直到），whenever（无论何时），as soon as（一……就）等。
When I went into the classroom, he was reading.
He read a newspaper as he went along.
We must strike while the iron is hot.
I will tell you after they leave.
I told him to e back whenever he wants to.
I waited till/until she was back.
Once time is gone, you will never get it back.
注意：在时间状语从句中，不能用一般将来时、过去将来时态或将来完成时，而要用相应的一般现在时态、一般过去时或现在完成时来代替。
I'll telephone you as soon as I get there.
Don't get off the bus until it has stopped.
二、含 time的短语
可引导时间状语从句的time短语有every time, each time, (the) next time, (the) last time, by
the time, the first time, any time 等。
Every time I listen to music, I'll think of it.每当我听音乐，我就想起这事。
He didn't tell me anything the last time I saw him.上次我见到他时他什么也没告诉我。
Each time she moved her head she let out a moan. 她每转动一下头，就发出一声呻吟。
三、表示“一……就……”
除as soon as外，还有三类：
名词型——the moment, the minute, the second, the instant；
副词型——immediately, directly, instantl y；
句式型——no sooner…than…, hardly/scarcely…when…。
The moment I saw him I knew that there was no hope.
I came immediately you called.
I had no sooner got home than it began to rain.
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.
四、对before从句的理解
before的本意为“在……之前”，根据具体语境还可理解为“还没来得及/还没有……就……，趁着还没……就……，不知不觉就……，……才……”等。
I had not sat long before he came back.我没坐多久他就回来了。
He almost knocked me down before he saw me. 他几乎把我撞倒才看到我。
Before I could get in a word, he measured me. 我还来得及插话，他就给我量好了尺寸。

Time passed quickly and three months went by before she knew it. 时间过得飞快，她不知不觉就在那里度过了三个月。
I will die before I will betray my country.我宁可死也不会背叛我的国家。
五、对since从句的理解
1. since从句的谓语动词是终止性动词照字面意思理解。
I've been feeling down since I lost my job. 自从失去工作后,我的情绪一直处于低潮。
2. since从句谓语动词延续性动词，且为现在完成时时，仍然按字面意思理解。
She has never e to see me since I have lived in the city.自从我住到城里，她就一直不来看我。
3. since从句谓语动词延续性动词，且为一般过去时时，按与字面意思相反的意思理解。
I have made great progress since I was ill.我自病愈以来取得了很大的进步。
4. since前有ever，或从句谓语动词是be且后接表示人成长过程中的某个阶段或年龄的名词、形容词时，仍然按字面意思理解。
I have lived here ever since I was a child.我从还是个孩子时就一直住在这儿。
六、对till/until从句的理解
1. 主句为肯定式，主句谓语动词必须为持续性动词，且该动词所表示的动作或状态一直延续到until / till 从句所表示的时间为止，可译作“（直）到……”。
He waited until/till I returned. 他一直等到我回来。
2. 主句为否定式（包括含no, nobody, nothing, never, hardly, little 等否定词的肯定句），若主句谓语动词是非持续性动词，则该动词所表示的动作在until / till 从句表示的时间开始发生。一般先译从句“直到……”，后译主句，not译成“才”，即“直到……才……”。
His mother didn't leave until/till he was asleep. 直到他睡着了，他母亲才离开。
Nobody can leave until/till the meeting is over.直到散会才能离开。
3. 主句为否定式，若主句谓语动词是持续性动词，则须根据上下文去理解until/till从句的含义，一般译为“直到……才……”或“没有到……”。
H e didn't wait until/till I returned. 他没有等到我回来。
She didn't sleep until/till I returned.她直到我回来才睡着。
原因状语从句
【高清链接】高清ID：396514 高清名称：时间、原因、条件状语从句
链接内容：原因状语从句
引导词：because, as, since, for
—Why did you do it?
—I did it because I was angry.
It was because I was angry that I did it.
I didn't help him, not because I was unwilling but because I was unable to.
only, just, simply, partly + because
You shouldn't look down upon a man just because he is poorly dressed.
as（由于，因为）引导的从句一般放在主句之前，说明原因，后边的主句说明结果。主从句的内容同等重要。在主句之后时，语气更弱；类似一种附带的说明，在口语中使用较多。
As there was no answer, I wrote again.
I got home late as I had to walk all the way home.
for是表示因果关系的并列连词，表示对主句内容的补充说明（可和because替换）或表示一种
推测判断（不可用because）。它引导的从句不能放在句首；需有逗与主句隔开。
He seldom goes out, for he is too old.
He must be asleep now, for there is no light on.
We listened attentively, for he was going to tell us who won it.
注意：以上连词不能与so同时使用。
条件状语从句
条件状语从句主要由if, unless, as/so long as, on condition that, suppose/supposing that,
provided that, in case 等引导。
I'll fire if you e any nearer.
You could get a better job if you spoke a foreign language.
Unless you wear boots you may be bitted by snakes.
Unless I parted from Sheila, l could not keep up that struggle.
As long as you understand, we shall say no more about it.

In case he arrives before I get back, please ask him to wait.
Suppose/ Supposing that they refuse us, who else can we turn to for help?
He has been granted his freedom on condition that he leaves the country.
虽然providing 和provided 形式上为动词provide的现在分词和过去分词，但它们均可用作连词，引导条件状语从句，其意为“只要”（=as long as）、“如果”（=if）等。如：
Providing /Provided you clear your desk by this evening, you can have tomorrow off.
只要你到今晚把案头上的工作做完，你明天就可以休息。
supposing本来是现在分词，但它们有可用作连词，引导条件状语从句，其意为“假若”“如果”等；此时主句通常为疑问句。如：
Supposing he can't e, who will do the work?
假使他不能来，这工作谁做?
注意：在条件状语从句中，通常要用一般现在时表示将来意义，而不能直接使用将来时态。不过，有时表示条件的if之后可能用will，但那不是将来时态, 而是表示意愿或委婉的请求(will为情
态动词)。如：
If you will wait a moment, I'll fetch the money.

高考英语状语从句专项训练
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。
