三、时间状语从句
（一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once.
（二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child.
While she was a child. She Lived in Paris.
As she was a child.
as有“一边…一边”的意思
He sang as he walked.
“when”
When the clock struck twelve, all the lights went out.
I was sleeping when she came in. 动补

“while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。
While we were having supper, all the lights went out.
Please keep quiet while others are studying.
While I was writing letters last night, he was watching TV.
when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。

并列连词引导并列句，意思是就在那时。
（三）、主句是一般将来时，时间状语从句用一般现在时表将来，主句是过去将来时，从句用一般过去时表示过去将来时，主句是一般过去时，从句用一般过去时。

3. I go to the theatre, whenever I am free.
4. Come and see me whenever you want to.你随时来看我。

1、在肯定句中表示“直到……为止”，主句谓语动词要用延续性动词。
I was waiting until/till he arrived.
2、在否定句中表示“直到……才”主句谓语动词常用终止性动词，这时until和till常被before替换。
I didn' t leave till/until she came back.
since: 主句用完成时，从句用一般过去时，since引导的从句间或可用现在完成时。

Since, as不回答why的提问，而且从句一般放在句首，because一般放在主句之后。
3、 before of +名词

4、 because 和so不可连用，只能选其一。（另有although, but）Why didn' t he come to school? Because he was ill.
Since I must die, I must. 既然我一定要死，我一定这样做。
Since a lot of people make mistakes in life, Mr Smith wanted to give John a Chance.
5、 for并列连词，不能放在句首，主要放在两个并列句之间。For所提供的理由为一个补充说明，而且前面常有逗号隔开。

such +形容词+可数名词单数+that
Such+形容词+可数名词复数（不可数名词）+that

although, though
even though = even if, whether…or
however = no matter how
whatever = no matter what
whoever = no matter who
whenever = no matter when

高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 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，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: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard. The moment he saw me, he ran away. 他一看见我，就跑了。 He said he’d call you the moment he got home. 他说他一到家就给你打电话 （3）The instant I saw him, I knew he was the man from the restaurant. （4）Immediately you begin to speak, he gives you his full attention.你只要一开始说话，他就全神贯注地听。 （5）My sister came directly she got my message. 我妹妹一收到我的信息就来了。 （6）Every time I listen to your advice, I get into trouble. （7）no sooner... than... ，"一...就..." ，引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. （8）He had hardly sat down when the telephone rang.他刚坐下电话就响了。 He had scarcely sat down when there was a knock at the door. 他刚坐下就有人敲门 另外，如果把hardly放于句首，主句要用倒装结构。如： Hardly had I finished eating when he came in. 我刚吃完他就进来了。 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories. She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句
条件状语从句 概念定义 由引导词if或unless引导的状语从句叫做条件状语从句。在英文中，条件是指某一件事情实现之后（状语从句中的动作），其它事情（主句中的动作）才能发生，通常译作“假如”。（注意：在含有条件状语从句的复合句中，表示将来时态，主句是一般将来时态,祈使句或情态动词，从句要用现在时态,[主将从现原则]（主将从现，将并非指将来时，还指表示将来含义的，跟着if后的那句话是从句。） 类型 条件状语从句 语法引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如： 1） If you ask him,he will help you. 如果你请他帮忙，他会帮你的。 2） If you fail in the exam,you will let him down. 如果你考试不及格，你会让他失望的 if引导的条件状语从句既可以将从句放前面也可以将从句放后面 （如果天下雨，我们就不玩了）If it rains,we will stop playing.‘ 转为We will stop playing if it rains. if引导的条件状语从句
另外，if从句还表示不可实现的条件或根本不可能存在的条件，也就是一种虚拟的条件或假设，从句多用一般过去时或过去完成时。如：If I were you,I would invite him to the party.如果我是你，我会邀请他参加聚会。I would have arrived much earlier if I had not been caught in the traffic.如果没有堵车，我会到的早一点儿。 那么，除了if之外，是否还有其他连词也可以引导条件状语从句呢?回答是肯定的，不仅有，还有很多。这些词由于出现的频率较小，且用法较复杂一些，所以不如if为大家所熟知罢了。下面就这些词的用法以例句的形式进行一下简单总结。 1、unless conj.除非，若不，除非在……的时候 You will fail to arrive there in time unless you start earlier.如果你不早点动身，你就不能及时赶到那儿。 Unless it rains,the game will be played.除非下雨，比赛将照常进行。 2、on condition(that)...在……条件下，如果 on condition (that)...引导的条件从句是主句事件发生的前提条件或唯一条件。 I can tell you the truth on condition that you promise to keep a secret.我可以告诉你真相，条件是你答应保密。 You can go swimming on condition (that) you don't go too far from the river bank.你只有在不远离河岸的条件下才可以下水游泳。 3、supposing conj.如果，假如 supposing引导的条件从句表示一种假设条件。 Supposing it rains,shall we continue the sports meeting?倘若下雨，我们的运动会还要继续举行吗? Supposing anything should go wrong,what would you do then?假如出了什么问题，你准备怎么对付?
