I get up when it is dawn. 状语从句
I get up at 6:00. 简单句
表示动作发生的时间、地点、原因、条件、目的、结果、方式等的句子成分叫做状语。而由句子来充当状语的，这样的句子就叫做状语从句。状语从句同副词、介词词组等做状语一样，用于修饰谓语或整个句子，说明它发生的时间、地点、方式、手段、条件、程度、比较、原因、目的、结果等，即在复合句中，作状语成分的从句叫状语从句。
常见的状语从句可分为：时间、原因、条件、 方式、让步、比较、结果、目的等从句。
I will call yu when I see him. If yu try it, yu will like it. Where there is water, there is life. Because he likes the game, he wrks hard. He wrks hard s that he can win. Even thugh he wins, he is nt happy. David tried his best, s he wn.
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考点。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，应将复习重点放在 和 上。
When/while/as(当…的时候), befre(在…之前), after(在…之后), until(直到…为止), as sn as(一…就), since(自从) .

当我正在打电子游戏时，爸爸在清洗汽车。
(g t bed表示的动作不能持续)
由when, while, until, as sn as, since等引导的状语从句就叫做
① when表示点时间时，从句中用短暂性动词；表示段时间时，用持续性动词。
② 当when的意思是“正当…时候”(and at that mment)时，when只能跟在前 一分句之后。
When they were still talking and laughing, the teacher came in.
When I arrived hme, my family were already having dinner.
我到家的时候，全家已经在吃晚饭。
当他们还在说笑的时候，老师进来了。
He was abut t g t bed when the drbell rang.
They had just arrived hme when it began t rain.
他正要上床，忽然门铃响了。
他们刚到家，天就开始下雨了。
（when表示点时间）
（when表示段时间）
① while通常表示一段时间，从句中宜用持续性动词做谓语。
Strike while the irn is ht.
She fell asleep while she was reading the newspaper.
②while有时可以作并列连词，表示对比，可译成“…然而…”
I’m fnd f English while he likes Maths.
我喜欢英语而他却喜欢数学。
我们睡觉而上尉担任警戒。
We slept while the captain kept watch.
While I was walking dwn the street, I came acrss an ld friend.

While I really dn’t like art, I find his wrk impressive.
while = althugh
While there is life, there is hpe.

I was sleeping, when smene kncked at the dr.When/While reading, he fell asleep.
√ 在时间状语从句里，主句为将来时，从句用一般现在时。
√ 若就时间状语从句提问，应用when来提问。.
I will ring yu up as sn as I get t New Yrk. I will tell him everything when he cmes back.He wn’t believe it until he sees it with his wn eyes.
While we were sweeping the flr, the bell rang.
When did the bell ring?
①某事一发生，另一事立即发生
As the captain passed me, I asked him whether there was any hpe f saving the ship.
As the day went n, the weather gt wrse.
as:当…时；一边…一边；随着…
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。
③ as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。
He sang as he went alng. 他边走边唱。 Please write while I read. 我读的时候，请写下来。When he reached hme, he had a little rest. 回到家后他休息了一会儿。
② as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 snwing when we gt t the airprt. （不能用while）
______ he had finished his hmewrk, he tk a shrt rest.______ he walked alng the lake, he sang happily.______ she was typing the letter, the telephne rang.

It will be half a year befre I cme back.
It will be half a year befre we meet again.
③ it wn’t be + 一段时间befre… 过不了多久就…
It wn’t be half a year befre we meet again.
肯定句中译为“才”否定句中译为“就”
till, until和nt…until的含义
① until/till引导时间状语从句用于肯定句时，主句的动词是延续性动词，表示动作或状态一直持续到until/till所表示的时间，意味“某动作一直延续到某时间点才停止”。
② 用于否定句时，主句谓语动词是非延续性动词，从句为肯定，意为“某动作直到某时间才开始”。
We waited until he came.
He will nt g t bed till / until she returns.
____________ he cmes here tmrrw, I will call yu.____________ he was walking in the street, he met Tim.She sang ____________ she wrked.It wn’t be lng ____________ he finishes his writing.____________ he had finished his wrk, he left there.It is tw years ____________ he came here.____________ she tld me, I had n idea f what they had said.

2. —Will yu please give dictinary t Jane? —Sure, I’ll give it t her _____ she arrives here. A. befre B. until C. because D. as sn as
本题考查时间状语从句，句意“她一到这儿，我就会给她”，befre“在..之前”，不符合逻辑;until“直到”，不能与短暂性动词give连用；because‘因为’, 不符合逻辑；as sn as“一..就”，符合句意。
3. I will send yu an email as sn as I ____ in Canada. A. arrive B. arrived C. am arriving D. will arrive

4. —What was yur brther ding at this time yesterday? —He was reading a magazine ___ I was writing an email at hme. A. as sn as B. after C. until D. while
重点关注时间状语从句的复习。
注意状语从句“主将从现”的时态考查：如果主句用将来时，从句要用现在时代替将来时。
注意易混连词的辨析及用法。
密切关注中考动向，确定以下备考方略
时间状语从句的备考方略
When/while/as(当…的时候), befre(在…之前),after(在…之后), until(直到…为止), as sn as(一…就), since(自从) .
if（如果）, unless（除非）, as lng as（只要）
由表示条件的关联词if或unless, as (s) lng as, nce, as far as 等引导的状语从句叫做条件状语从句。
某一件事情实现之后其它事情才能发生
We’ll start ur prject ______ the president agrees.
Yu will certainly succeed ______________ yu keep n trying.
____ it desn’t rain tmrrw, we will g there by bike.
as(s) lng as
如果总统同意的话，我们就开始我们的项目。
只要你继续尝试，你就肯定能成功。
如果明天不下雨，我们就骑自行车去那里。
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…nt. 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：Yu will fail ________ yu study hard. Yu will fail if yu dn’t study hard.除非你努力学习，否则你会失败
it snws tmrrw, we will build a snwman.
明天如果下雪，我们就堆雪人。
Yu’ll catch a cld yu put n yur cat.

7. If yu _____ him tmrrw, please ask him if he ____ t wrk n the farm with us. A. see; ges B. will see; ges C. will see; will g D. see; will g
条件状语从句考的频率比较高，主要考察if连词和if引导的从句与主句的时态。
注意从句与时态的并行考查
前引：根据主从句的三种时间关系，分为主从句同时发生、主从句都没有发生、 主从句一前一后发生三类句型，每种句型分别对应独特的句式
What were yu ding when the UFO arrived?
What are yu ding when the UFO arrives?
I wuld leave if he came.
I will leave if he cmes.
The train had been away when I arrived.
过去类：过去进行 when 一般过去
现在类：现在进行 when 一般现在
过去类：过去将来 when 一般过去
现在类：一般将来 when 一般现在
过去完成 when 一般过去
“祈使句+ and (r) + 陈述句” 在意思上相当于一个带有条件状语从句的复合句。 其中，and表示句意顺承；r表示转折，意为“否则”。例如：
用介词with, withut可以把条件状语从句改写成简单句。
Hurry up, r yu’ll be late. If yu dn’t hurry up, yu’ll be late.Study hard and yu will pass the exam. If yu study hard, yu will pass the exam.
If there is n water, the fish may die. Fish may die withut water.If yu help me, I’ll finish my task n time. With yur help, I’ll finish my task n time.
考查if引导的条件状语从句。当主句是一般将来时，if引导的条件状语从句应该用一般现在时。句意为“如果这个星期天不下雨的话，我们进行野餐。”
1. —We’ll g fr a picnic if it ____ this Sunday. —Wish yu a lvely weekend. A. rain B. desn’t rain C. wn’t rain
本题考查条件状语从句。联系上下文可知：如果不尽力，他们会输。unless(除非) = if…nt(如果不)
1. They will lse the game ________ they try their bests. A. unless B. nce C. since D. after
本题考查if引导的条件状语从句。根据句意：“如果我们不保护地球，我们将没有水喝。”
1. We will have n water t drink ____ we dn’t prtect the earth. A. until B. befre C. thugh D. if
注意状语从句与时态的并行考查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
条件状语从句的备考方略
where（哪里）, wherever（无论哪里）
because, as, since（既然）
