状语从句讲解
状语从句讲解状语从句是英语语法中的一个重要概念，它在句子中起到修饰谓语动词或整个句子的作用。
本文将详细解释状语从句的定义、功能和常见类型，并给出一些例句以帮助读者更好地理解和运用状语从句。
状语从句是一个从句，它在句子中充当状语的角色，用来说明动作发生的时间、地点、原因、方式、条件等情况。
状语从句通常由连词引导，常见的引导词包括when（当...时候）、where（在...地方）、why（为什么）、how（如何）等。
通过使用状语从句，我们可以使句子更加丰富、具体和准确。
首先，让我们来看一下状语从句的功能。
状语从句可以用来表示时间关系。
例如，“I will call you when I arrive home.”（当我到家时，我会给你打电话）这个例句中的状语从句“when I arrive home”说明了动作“call”发生的时间。
其次，状语从句可以表示地点关系。
例如，“She looked around to see where the noise was coming from.”（她四处看看，想知道声音是从哪里传来的）这个例句中的状语从句“where the noise was coming from”说明了动作“look around”的地点。
此外，状语从句还可以表示原因、条件和方式等关系。
例如，“He couldn't go to the party because he was sick.”（他因为生病所以不能去参加聚会）这个例句中的状语从句“because he was sick”表示了动作“couldn't go”的原因。
在使用状语从句时，需要注意一些语法规则。
首先，状语从句通常放在主句之前或之后，具体位置取决于需要强调的内容。
其次，状语从句的谓语动词通常使用一般现在时，而不受主句的时态影响。
例如，“I will call you when I arrive home.”（当我到家时，我会给你打电话）中的“arrive”使用的是一般现在时。

(完整版)状语从句讲解
状语从句定义：在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。
状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。
状语从句主要用来修饰主句或主句的谓语。
一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。
尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。
状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊的连接词即考点。
现分别列举如下:一、时间状语从句1.when, while和as的用法(1)when既可引导一个持续动作，也可引导一个短暂性动作.when强调主从句动作的发生有先后。
如：①When he got there, the classroom had been cleaned.他到的时候，教室已打扫过了。
(主句动作发生在从句动作之前)②He went to play football when he finished his homework.做完作业后他就去踢足球了。
(主句的动作发生在从句动作之后)when可作并列连词用，相当于just then，at the time，前一分句多用进行时、be about to或be on the point of doing，表示“正在做..，就在这时发生了另外一件事”或“届时”。
如：①I was reading when he suddenly came in.②I was about to leave when the telephone rang.(2)while强调主句动作发生在从句动作所发生的时间段内，从句的动作必须是延续性动词。
如：①Strike iron while it’s still hot.②Will you please take care of my house while I was away?在这一情况下，从句的动作一定是延续性动词，如果是非延续动词，要用when。
状语从句的时间原因条件等用法详细讲解
状语从句的时间原因条件等用法详细讲解状语从句的时间、原因、条件等用法详细讲解状语从句是指在复合句中作为状语的从句，用来修饰、限制主句中的动作或状态。
在英语中，状语从句主要有时间、原因、条件等多种用法。
下面将详细讲解状语从句在时间、原因、条件等方面的应用。
一、时间状语从句时间状语从句是用来表示主句中的动作或状态发生的时间或顺序关系。
常见的引导时间状语从句的连词有：when（当...时候）、before （在...之前）、after（在...之后）、as soon as（一...就）、while（当...的时候）、until（直到...为止）等。
1. 当...时候当主句中的动作或状态发生时，使用连词when引导时间状语从句。
例如：I will call you when I arrive home.（当我到家的时候，我会给你打电话。
）2. 在...之前表示主句中的动作或状态发生之前，使用连词before引导时间状语从句。
例如：Please finish your homework before you go out to play.（在你出去玩之前，请先完成作业。
）3. 在...之后表示主句中的动作或状态发生之后，使用连词after引导时间状语从句。
例如：She always helps her mother after she finishes her homework.（她总是在完成作业后帮助她的妈妈。
）4. 一...就表示主句中的动作或状态一发生，立刻使用连词as soon as引导时间状语从句。
例如：He went to bed as soon as he got home.（一到家，他就去睡觉了。
）5. 当...的时候表示主句中的动作或状态正在进行时，使用连词while引导时间状语从句。

状语从句讲解
状语从句讲义状语从句在复合句中作状语，其位置较灵活，可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号，放在句末时状语从句前面往往不用逗号)。
时间状语从句when, while, as, before, after, till/until, since, as soon as地点状语从句where原因状语从句because, since, as, for方式状语从句as, as if / though目的状语从句so that, in order that结果状语从句so…that…, such…that… , so that条件状语从句if, unless,让步状语从句although, though, as一．目的状语从句的用法目的状语从句用以补充说明主句中谓语动词发生的目的。
可以由表示“为了，以便，目的是”的so that(有时省略so)，in order that引导,或in case “以防”引导。
谓语常含有may, might, can, could, should, would等情态动词。
【注意】in order that与in order to的区别：in order that+从句in order to+动词原形（in order to后面加的那个不叫目的状语从句，叫目的状语）例：They both worked day and night in order that they could pay off their debt.= They both worked day and night in order to pay off their debt.他们夜以继日地工作以便能把债还清。
目的状语从句的一个特点：由于目的都是未来的行为，所以从句中一般用表示未来可能性时态，比如上面两句中的could。
当然还可以用will, would, can,等//They set out early (so)that they might arrive in time.他们早点动身，以便及时到达。
状语从句讲解
(1) 当主句为将来时态或具有将来意义时，时间状语从 句通常要用一般现在时表示将来意义。 Turn off the lights before you leave. I will tell him as soon as he arrives. (2) 与since 从句搭配的主句的时态通常是现在完成时 态。 He has lived here since 1999. Where have you been since I last saw you?

状语从句3．1 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。
3．2 原因状语从句(1) because 只能它能用来回答why引导的问句。
可以与just, only 连用。
My friends dislike me because I am handsome and successful.Just because I don’t complain (抱怨), people think I am satisfied.(2) Since 表示人们已知的事实，不须强调的原因，通常译成“既然”。
Since ev eryone is here, let’s get started.Since you are sleepy, you might just as well go to bed.(3) As 和since 的用法相似，所引出的理由在人们看来已经很明显，或已为人们所知。
She didn’t hear us come in as she was asleep.As Monday is a national holiday, all government offices will be closed.(4) For 表示推断的理由，对前面的分句内容加以解释或说明，通常放在主句后面。
The days are short, for it is now December.It rained last night, for the ground is wet this morning.3．3 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.“以免，以防，生怕, 万一”for fear that, lest, in caseBetter take more clothes in case the weather is cold.He wrote the name down for fear that/lest he should forget it.Take an umbrella with you lest it should rain.She cleans the window with great care lest she might break the glass.Take an umbrella, in case it rains.He had his camera ready, just in case he saw something that would make a good picture.3、4 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su ch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.3．5 条件状语从句连接词主要有if, unless, as/so long as, on condition that, suppose that, supposing (that), p roviding/provided 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.I may lend you the book on condition that you return it to me in time.Suppose nothing happens to you.He will surely finish the job on time _____ he’s left to do it in his own way.A. in thatB. in caseC. as far asD. so long as (D)You will be late ___ you leave immediately.A. unlessB. untilC. ifD. orA。
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 w ill be late.3．6 让步状语从句1) 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）___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.Young as he is, he is knowledgeable.Poor as he is, he is honest and kind.Much as I respect him, I can’t agree with him.Try as he will, he can’t persuade his brother.Lose money as I did, I got a lot of experience.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。
