高中英语之状语从句讲义
状语从句一、基本概念定义：在复合句中由从句表示的状语称作状语从句，它可以用来修饰谓语（包括非谓语动词）、定语或状语，或是整个句子。
状语从句通常由一个连词引起，也可以由一个起连词作用的词组引起，有时甚至不需要连词直接和主句连接起来。
状语从句一般分为九大类（见下表）：状语从句类别时间状语从句地点状语从句原因状语从句目的状语从句结果状语从句条件状语从句方式状语从句比较状语从句让步状语从句1．时间状语从句：在时间状语从句中，要注意时态一致，一般情况下主句是将来时的时候，从句要用一般现在时。
可以引导时间状语从句的连词很多，根据意义和主从句之间的时间关系，又可分类如下：(1) 表示同时性，即主从句的谓语动作同时发生或几乎同时发生。
其连词有：when （当……的时候）, while（当……的时候）, as（当……的时候）, as soon as（一……就……）, once（一旦……）等。
如：Strike while the iron is hot. 趁热打铁。
While I am washing the floor, you can be cleaning the windows.（while含有对比的意思）我洗地板的时候，你可以擦窗户。
As / When I came home, I met an old schoolmate of mine.我回家的时候遇到了我的一位老同学。
I’ll ring you up as soon as I get an answer from him.我一有他的答复就给你打电话。
Once you see him, you will never forget him.你一旦见过他，就不会忘了他的。
(2) 表示先时或后时，即主句的谓语动作发生在从句之前或之后，主要连词有：after （在……后）, before （在……之前）, when (=after)等。
如：After / When the children had gone to bed, she began to prepare her lessons.（从句的动作发生在主句的动作之前，所以从句用了过去完成时）孩子睡觉了以后她开始备课。

状语从句在复合句中作状语，位置灵活。
状语从句可分为时间状语从句，地点状语从句，原因状语从句，条件状语从句，让步状语从句,目的状语从句，结果状语从句,方式状语从句，比较状语从句。
时间状语从句1.when, as, whilea.when表时间，从句既可以用延续性动词，又可以用瞬间动词。
When I get there I will call you.如果when引导的时状的主语与主句的主语相同，而从句的谓语又是be动词时，那么从句中的主语与be 可省。
如果when引导的时状的主语与主句的主语相同时，往往可以用“when+分词”的形式代替该状从。
When （you are）in trouble, you can ask her for help.When I came into the room(When coming into the room), I found the light was off.b.while表时间，从句需用延续性动词，或者主句的动作发生在从句的动作进行过程中。
He came in while I was reading a book. I met her while I was in school.c. as表时间，与when相似，但侧重强调主从句动作同在时间点或同时间段进行。
同时可表示主句的动作随着从句的动作的变化而变化。
He jumps as he sings. As the wind rose, the noise increased.2.before(在……之前)与after（在……之后）See me before you leave. I saw them after I arrived.3. till与until肯定形式表示的意思是"做某事直至某时"。
否定形式表达的意思"直至某时才做某事"。
Wait till/untill I call you. 等着直到我叫你。
She didn't arrive till/until 6 o'clock.. 她直到6点才到但是置于句首时只可用until.Until you told me, I had heard nothing of what happened. 直到你告诉我以前，出了什么事我一点也不知道。
否定形式有另外两种表达方式：(1)Not until …在句首，主句用倒装。
Man did not know what heat was until the early years of the 19th century.=Not until the early years of the 19th century did man know what heat was.(2)It is not until…that…He will not go to bed until his mother comes home. =It is not until his mother comes home that he will go to bed.4. as soon as/the moment/the instant/the second/the minute/immediately 和hardly/scarcely…when, no sooner…thana. as soon as/the moment/the instant/the second/the minute/immediately 表示主句和从句的动作同时发生。
译为“一……就”：The moment she heard the news, she began crying.b. hardly/scarcely had sb done …when sb did…, no sooner had sb done…than sb did …表示"一…就…"的意思，I had hardly / scarcely got home when it began to rain.=Hardly / Scarcely had I got home when it began to rain.I had no sooner got home than it began to rain.= No sooner had I got home than it began to rain注意：如果hardly, scarcely 或no sooner置于句首，句子必须用倒装结构。
地点状语从句1. where: 哪里Eg: Put the medicine where you can easily get it.2. wherever：无论哪里Eg: He follows her wherever she goes. Wherever you are, I will be right there waiting for you.原因状语从句1. because—直接原因，非推断．语气最强．回答why。
Eg：I do it because I like it.2. as–不谈自明的原因，语气最弱。
Eg:As he is honest and modest, all his friends like him.3. for–放句中，对前面一句话的内容的补充说明。
从句只能置于主句之后并且必须用逗号与主句隔开。
Eg: He could not have seen me, for I was not there.4. since/ seeing (that)/ now (that)/ considering (that)/ in that –通常放句首．译为“既然”。
Eg: Since the purser didn’t tell us what to do, we can relax.条件状语从句1. if: “如果”(如为真实条件句用陈述语气、如为非真实条件句用虚拟语气)If it snows tomorrow, the flight will be canceled. If I were a bird, I would fly.2. in case, on condition that, providing, provided (that), supposing, supposed (that) :“假如，在……条件下”The mother promises to the son to buy him a toy airplane on condition that he passes his English test.Suppose (that) he does not come, what shall we do?3. unless:“除非”（=if not）We can’t get there on time unless we book the earliest flight= We cannot get there on time if we don’t book the earliest flight.3.as/so long as:“只要”Eg: We will succeed as long as we keep on trying让步状语从句1. “虽然，即使，尽管”a. although/ though/ even though/ even ifalthough/ though 语气较弱（尽管），even though/ even if（即使）语气较强。
Eg: Although/ though it was not his fault, he took all the blame.Even if/ Even though you don’t like your boss, you should do your work.b. as as可引导让步状语从句，表示“虽然、尽管”，但要用倒装结构，形式如下：1）. 形容词/过去分词/名词+ as + 主语+ 系动词副词+ as + 主语+ 谓语部分Tired as he is, he offers to help me. Well-written as the book is, the author is not satisfiedStudent as he is, he does not study hard. Much as I admire his courage, I don’t thin k he acted wisely. though在引导让步状语从句时可像as一样倒装。
2. while: 尽管While it’s none of my business, I will watch you.3. no matter (what, when, where): 无论（什么，何时，何地）The old man wouldn’t believe anything no matter what you said.Please tell me the result no matter when you get it.4. however :不论怎样。
however引导让步状语从句时，句子通常倒装，一般在however后加形容词或副词。
Eg: The father couldn’t make his daughter smile however hard he tried.5. whether…or not: 不管是否: Whether he is good or not, the company decided to send him abroad.总结：1)although与though在一些情况下可互换，都可以与yet，still连用，但不能和but连用。
2)however引导让步状语从句时后紧跟形容词或副词。
3)while也可引导让步状语从句，这一点特容易被考生忽视。
4)whatever修饰名词，“无论什么”，however修饰形容词、副词，“无论多么，无论怎么”。
5)even if/even though(即使)与as if/as though(好像)目的状语从句1. (so) that/in order that表示“为了，以便”He shouted at the top of his voice so that/in order that he might be heard.如果表示“为了，以便”的目的状语从句的主语与主句的主语相同，可用in order to或so as to替代。
