状语从句知识点详解（初中英语专项复习）状语从句的概念: 用一个句子作状语来修饰动词和形容词，以表明动作发生或状态存在的时间、地点、原因等，这个句子就叫做状语从句。
状语从句的分类：状语从句共分为九大类，包括：时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。
下面分别讲解：一、时间状语从句概念：用来表示时间的状语从句，由when, while, as, till, until，before, after, since等引导。
由于时间状语从句的引导词所表示的意思并非一致，不同引导词表达不同的时间，它们在句子中对应的时态、语态等也有所不同。
例如：when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词，也可以是延续性动词。
从句动作可与主语动作通常先后发生也可同时发生。
I was writing when my sister came back.( come是瞬间动词，只能用when引导，不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词，while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词，cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋，而我姐姐喜欢看小说。
(while表示对比)when和while的区别还有：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While we were playing games, our headmaster called me .我们正在做游戏的时候，校长叫我了。

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。

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。
如：①Will you please take care of my house when I went away?②当我进来的时侯，他在和别人说话。
While I came in, he was talking with others.When I came in, he was talking with others.(3)as引导一个持续性动作，强调主从句的动作同时发生，有“一边..一边..”的意思，也可说明两种正在发展或变化的情况，有“随着..”的意思。
如：①He sang as he walked.他边走边唱。
②As he gets older, he gets more open.随着年龄的增长，他越发开朗起来。
2.as soon as, the moment, the minute, the second, the instant, no sooner...than, hardly/scarcely...when...，immediately, directly, instantly的用法。
这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一……就……”，The moment she arrives，we can start.No sooner had we arrived at the station than the train left.The boy burst into tears immediately he saw his mother.3.till, until和not...until的用法(1)在肯定句中，主句谓语动词必须是延续性动词，意为“某动作一直延续到某点才停止”。
You may stay here till/until the rain stops.你得在这里呆到雨停。
(2)在否定句中，主句谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。
He won't go to bed till (until) she returns.直到她回来他才睡。
(3)not...until句型中的强调和倒装说法。
It was not until you told me that I had any idea of it. (强调句型)Not until you told me did I have any idea of it. (not until 置于句首，主句要倒装)Not until he came back did he find his house had been broken into.4.before和since的用法(1)连词before表示“还未……就……”，“不到……就……”，“……才……”，“趁还没来得及……”。
Before they reached the station, the train had gone.We hadn't run a mile before he felt tired.Please write it down before you forget it.(2)before的句型：It will be＋时间段＋before从句，表示“多久之后才……”。
It will be half a year before I come back.It won't be long before we meet again.(3)since的句型：It is/has been＋时间段＋since从句。
若从句谓语为非延续性动词，表示“自从……有多久”；若从句的谓语为延续性动词，表示“自从结束/完成……起有多久”。
It is three years since the war broke out.It is three years since he lived here.二．地点状语从句1.地点状语从句可用where, wherever, anywhere, everywhere等引导。
地点状语从句可用于主句之前或之后。
You are free to go wherever you like.Where there is a will, there is a way.有志者，事竟成。
Wherever there is smoke, there is a fire.无火不生烟(既无风不起浪)。
2.注意区分引导的定语从句与状语从句。
where引导的地点状语从句直接修饰动词，而在定语从句中where作为关系副词要跟在表示地点的先行词后面。
You'd better make a mark where you have any questions.(状语从句)You'd better make a mark at the place where you have any questions.(定语从句)三．原因状语从句1.引导原因状语从句的从属连词有：because, as, since, now that, seeing that, considering that等，每个连词的含义不尽相同。
(1)because用来回答why的提问，语气最强，一般放在主句之后；(2)since表示既然或已知的理由，稍加分析即可表明的原因，多放在句首；(3)as多用于口语，语气比because，since弱，表示的理由是明显的或被认为是已知的，是对主句的附带说明，重点在主句，可放在句首或句尾，放在句尾时，as可省略。
I can’t go，(as) I am busy.(4)considering that, seeing that, now that和since的意义相似，都有“鉴于某个事实”的意思，that 可以省去。
As it is raining, we shall not go to the park.Now that/Since everybody is here, let's begin our meeting.既然大家都到了，我们就开始我们的会议。
My friends dislike me because I’m handsome and successful.Now that everybody has come, let’s begin our conference.四．目的状语从句引导目的状语从句的从属连词有：so that, in order that, for fear that，in case, lest等。
1.in order that与so that两个连词都意为“以便……，为了……”，引导的状语从句中需用情态动词；in order that比so that正式，引导的状语从句可置于主句之前或之后，而so that引导的从句只能置于主句之后。
I'll speak slowly so that you can understand me.In order that we might see the sunrise, we started for the peak early.The boss asked the secretary to hurry up with the letters so that he could sign them.2.for fear that, in case与lest这些从属连词本身带有否定意义，意为“以免，以防”，相当于so that...not...或in order that...not...The boy hid himself behind the tree in case/for fear that his father should see him.Take your raincoat in case/lest it should rain.五．结果状语从句1.引导结果状语从句的从属连词有：so that, so...that...，such...that...。
其结构形式为：Mike is so honest a worker that we all believe him.＝Mike is such an honest worker that we all believe him.He earned so little money that he couldn't support his family.He got up so early that he caught the first bus.It’s such a good chance that we must not miss it.区别so...that和such...that的用法名前such，形、副so，that从句跟在后；多多少少必用so，特别注意是little；“小”用such，“少”用so。
