高三英语语法一轮复习时间、地点、条件状语从句考点总结讲义
高考英语二轮复习时间、地点、条件状语从句考点总结讲义（基础篇）状语从句状语从句又叫副词从句，用途非常广，却非常简单，简单到中学学习时都没有费太多笔墨，为什么？因为状语从句都有非常明显的代表某种逻辑的标志词，这些标志词总共有九类，也就意味着状语从句分为九种。
分别为：时间、地点、条件、原因、结果、目的、让步、方式、比较。
首先，我们先明确一些理念。
状语从句和并列句的比较1. I am going to leave the party early so that I can get a good night’s sleep.（我要早点离开聚会，那样的话我就能好好睡一觉。
）2. I am going to leave the party early and I want to be able to get a good night’s sleep.（我要早点离开聚会，我要好好睡一觉。
）句1是一个复句，有主句有从句，so that引导的状语从句和前面的主句都是完整、独立的简单句，中间用so that连接；句2是和个合句，逗号前后都是完整的简单句，由一个并列连词and连接，需要注意and两边的句子没有主从之分，相互也不需要解释。
句1这个状语从句由从属连词so that连接，使得so that I can get a good night’s sleep的地位下降，成了前面主句的附属句，当副词使用（目的状语），用来修饰主句“离开聚会早”的目的是“回家好好睡一觉”。
总的来看这两个句子，状语从句的从属连词给句1带来了从属关系，除开这层修饰关系，状语从句和句2的并列句并无二致，同样表意单纯。
状语从句和名词性从句3. The witness said that he saw the whole thing.（证人说他目睹了事情发生的全过程。
）4. The witness said this, though he didn’t really see it.（证人这样说，尽管他没有真正看到。
高三英语一轮复习之--高考英语中最常考的八类状语从句
高考英语中最常考的八类状语从句状语从句是高考英语的必考考点，综观近年来各省市状语从句的考题情况，以下八类状语从句特别值得关注：一、in case引导的状语从句根据语境的不同，in case既可表示“如果”“万一”，引导条件状语从句；也可表示“以防(万一)”，引导目的状语从句。
下面两道真题均选in case：1. Leave your key with a neighbor ______ you lock yourself out one day. (北京卷)A. ever sinceB. even ifC. soon afterD. in case2. My parents live in a small village. They always keep candles in the house ______ there is a power cut. (重庆卷)A. ifB. unlessC. in caseD. so that【解析】两道题都选in case，均表示“以防万一”。
二、before引导的状语从句尤其要注意“it+be+一段时间+before…”这一句型。
如：1. The field research will take Joan and Paul about five months; it will be a long time ______ we meet them again. (安徽卷)A. afterB. beforeC. sinceD. when2. He was told that it would be at least three more months ______ he could recover and return to work. (江西卷)A. whenB. beforeC. sinceD. that【解析】两道题均before。
第1题涉及的句式为：It will be a long time before…，意思是“要过很久才会……”；第2题涉及的句式为：it was some time before…，意思是“在……之前过了一段时间”，通常可转译为“要过一段时间才会……”。
高三英语一轮复习状语从句讲义以及练习题(高考总复习,纯干货,原创)
1.状语从句概念？状语从句指句子用作状语时，起副词作用的句子。
状语从句在高考中考察基本是以翻译从句引导词为主。
2.分类以及各个从属连词用法？2.1时间状语从句(when，while，as, no t…until, since,before……)when，while，as区别：while用引导的动作必须是持续的，侧重于主句动作和从句动作相对比e.g I was cooking at noon while she was sleeping.as“一边…一边…”或着“随着”e.g He was looking behind as he walked.As times flies, the weather is getting cooler and cooler当主句表达短暂性动作，而从句表示一段时间内的延续性动作时，.用三者都可以I met Jim when/while/as I was riding in Heping Road.其他：as soon as, immediately, directly, the moment, the instant, once(一…就…)The boy burst into tears immediately he saw his mom.I will leave here as soon as I get my visa.(主将从现：if/as soon as/when/until 引导的时间状语从句)no sooner…than…; hardly…when…; scarcely…when…(一…就…, 但含有否定意味的词置于句首时，主句要部分倒装)(hardly…before…; scarcely…before…)主句用过去完成时，从句用一般过去时。
I had hardly got home when it began to rain.Hadly had I got home when it began to rain.No sooner had we reached at school than the bell went.till/untill(直到till不可以用于句首), not…until（直到…才…）注意not until强调句用法和倒装句用法。
高三英语大一轮复习讲义 语法知识 专题八 状语从句 新人教版
专题八 状语从句、定语从句状语从句一、时间状语从句1．before 引导的从句中不用否定式谓语。
常用如下句型： It is long before...(过了好久才……) It is not long before...(过了不久就……)2．since 后面所用动词不同，该动词所表示动作持续时间的计算方法也不同。
⎩⎪⎨⎪⎧since ＋瞬间动词过去式从该动作发生时算起since ＋持续性动词过去式从动作结束时算起It is two years since he joined the army. It is two years since he smoked. 二、地点状语从句多由where 和wherever 引导。
Where there is a will ，there is a way. 二、原因状语从句在表示原因时，because 语气最重，其次是as ，since ，now that ，故在回答why 问句或者在强调句对原因进行强调时，只能用because 。
for 是并列连词，表示推测的理由或者进一步说明，不能放在句首，for 前要用逗号。
—Why were you absent? —Because I was ill. 三、目的状语从句1．so that/in order that 引导的目的状语从句中的谓语动词多用can/could/may/might/will/would ＋动词。
Please turn off the light so that I can go to sleep. 2．for fear that ，in case ，lest 表示“以防，免得”。
He is working hard for fear that he should fail. 四、条件状语从句1．providing/provided (that)假如，假若Providing (that) no one has further questions ，the meeting will be over. 2．on the understanding that ＝on condition that 在……条件下I give you money on the understanding that you finish your homework.五、结果状语从句注意such 引导的结果状语从句与定语从句的区别。

20XX年高考英语一轮复习学案专题12：状语从句【备考策略】一、地点状语从句地点状语从句通常由where, wherever 引导。
Where I live there are plenty of trees.我住的地方树很多。
Wherever I am I will be thinking of you.不管我在哪里我都会想到你。
二、方式状语从句方式状语从句通常由as, (just) as…so…, as if, as though引导。
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。
三、原因状语从句比较：because, since, as和for1）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.四、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.五、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 foolso nice a flower such a nice flowerso many / few flowers such nice flowersso much / little money. such rapid progressso 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六、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. unlessB. untilC. ifD. 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.七、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. WhenB. HoweverC. AlthoughD. 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 = whateverno matter who = whoeverno matter when = wheneverno matter where = whereverno matter which = whicheverno 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。
比较while, when, as1）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。
