状语从句讲义(讲稿)
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。
英语中的九种状语从句
5、条件状语从句的引导词有if, if only（如果…… 就好了，但愿）, unless, in case, as/so long as, provided that, providing that, suppose that, supposing that, on condition that ， when。
(1)___the days went on, the weather got worse.
A. With
B. Since
C. While D. As
(2) ____the satellite launch drawing near，the research workers put their hearts to the test and always stayed up late.
状语从句
状语从句 （Adverbial Clause） 是指句子用作状 语，根据其作用可分为一下九种：
1. 时间状语从句 1) 引导词 （ 1 ） 表 示 “ 当 …… 时 候 ” ： when, while, as,
whenever When I went into the room, he was at work.当我进屋
Even if I have to walk all the way I’ll get there. 即使我 得一路走着去，我也要走到那里。
• as引导的让步状语从句的结构是：名词（形 容词、副词、动词）+ as +主谓。如：
Child as he was, he knew what was the right thing to do. 尽管是个孩子，他知道要做的正确的事情 是什么。
状语从句(9种全)
状语从句在复合句中作状语的从句叫状语从句。
状语从句有时间、地点、原因、目的、结果、条件、方式、比较、让步等种类。
一、时间状语从句引导时间状语从句的连接词有: when, as, while, after, before, since, ever since, as soon as, once, till, until, whenever, no sooner…than, hardly/scarcely...when, themoment/minute/instant/second, every time, each time, any time, the first time, next time, last time, all the time, by the time, directly, immediately, instantly等。
1.表示“一···就···”的句型1) as soon as/onceAs soon as he arrives, I'll call you.他一到，我就给你打电话。
（as soon as 侧重时间或动作先后衔接紧，而once侧重条件，表示“一旦...”）2) on doing sth/on one's + n.作时间状语On arriving at the station, the thief was arrested.一到达车站，这个小偷就被逮捕了。
On his arrival in Paris, he was recognized as a noble and thrown into prison. 他一到达巴黎，就被认出是一个贵族，并被投入监狱。
3) no sooner ...than , hardly/scarcely...when它们表“一…就”。
结构中的否定词放在句首时，主句要倒装。
时间状语从句2
时间状语从句25.as soon as“一……就……”，引导时间状语从句时，表示主句动作紧接着从句动作发生。
如：I’ll call you as soon as I get home.我一到家就给你打电话。
6.until, till“直到”，引导时间状语从句。
当主句谓语动词是延续性动词时，主句常用肯定形式；当主句谓语动词是非延续性动词时，主句要用否定形式，即“not…until/till…”意为“直到……才……”。
如：I’ll wait here until/till the rain stops.我将在这里等着，直到雨停。
You can’t go home until/till you finish your work.直到你完成你的工作，你才能回家。
7. since 表示自从通常是现在完成时8. as 当主句. 从句动作同时发生，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件只能是as 为一边一边A s the weather went on the weather got worse下面再向大家透露点儿内幕消息，状语从句的两手绝活——时态的呼应和从句的位置。
请看：一、时态呼应一般来讲，复合句都要遵循主、从句时态呼应规律，状语从句也不例外。
即主句用现在时，从句也用现在时；主句用过去时，从句也用过去的某种时态。
如：Be careful when you cross the road.过马路时要小心。
You must see the doctor if you are ill.如果你生病了，你必须去看医生。
主句是一般过去时，从句也要用一般过去时。
如：When he was seven years old, he could swim.当他七岁时就会游泳。
She turned off the light before she left the office.她离开办公室前就关了灯。
二、主从句的位置。
状语从句2 条件状语从句
状语从句---条件状语从句（1）if 和unless 引导的条件状语从句。
if 表示正面的条件，意为“如果”；unless(=if---not )表示反面的条件，意为“除非，如果不”。
Eg. ①If you had come a few minutes earlier, you would have met him.②I may not come to see you recently unless I can complete the project ahead of time.(2)in case, on condition that, providing(that), provided(that), supposing (that), suppose(that )等词汇意思相近，意为“万一，假设，假如，在---条件下”。
①In case there is a fire, what will we do first?②Supposing/suppose(that)they refuse us, who else can we turn to for help?They agreed to lend us the car on condition that we returned it before the weekend.典例 The company promised to give us a discount we pay in advance.A.even ifB.as ifC. so thatD. provided that(3)as long as (=so long as )引导语气强烈的条件状语从句，意为“只要”。
Eg. I don't mind where you go, as long as you're back before midnight. (4)在“祈使句+and/or/or else/otherwise+陈述句”句型中，祈使句在意义上相当于条件状语从句。
语法专项2—— 状语从句(九大状语从句详讲+配套练习)
语法专项2——状语从句【状语从句综述】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，它能够用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。
一、时间状语从句1.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。
例如：When I ca me into the office, the teachers were having a meeting.当我进入办公室时，老师们正在开会。
He started as soon as he received the news. 他已得到这个消息，就出发了。
Once you see him, you will never forget him.一旦你见了他，你就不会忘记他。
No sooner had I gone to bed than I went to sleep.我一上床就睡着了。
2.when, while, as的区别这三个词都能够用作连接词，表示时间关系，但有所区别。
(1)when表示时间关系时，意思常常是“当(在)……的时候”。
主句和从句中的动作或事情能够同时发生，也能够先后发生。
例如：When we were at school, we went to the library every day.我们在求学的时候，每天都到图书馆去。
(2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，主句中的动作或事情在从句中的动作或事情的进展过程中发生。
它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。
