状语从句知识点详解(初中英语专项复习)14
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。

(完整版)中考英语状语从句考点归纳与例析
中考英语状语从句考点归纳与例析【重点讲解】中考英语试题对状语从句的考查主要涉及引导状语从句的从属连词的用法。
单项选择题的四个选项往往是四个连词，这是状语从句最常见的考查形式。
另一个考点是状语从句中的时态，因此，在学习状语从句时要弄清状语从句的几个主要类别，如时间、地点、原因、条件、让步、方式、目的、结果等，同时记住它们的“引导词”及其相关意义。
考点一：引导状语从句的连词的选择。
1、引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/until, as soon as等。
其中when，while和as都可表示"当……时候"，但用法有区别:when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以是终止性动词,也可以是延续性动词。
例如:When I got home, he was having supper.as意为"边……边……"或"与……同时",重在表示两个动作同时发生。
伴随进行。
as从句是终止性动词时,主句通常也必须是终止性动词。
例如: They sang as they danced.while只可表示"段时间",从句谓语只限于延续性动词。
例如:While I was sleeping, my father came in.注意：从句谓语是持续性动词时,when，while和as可以互换。
主、从句谓语都是终止性动词时，when与as可互换。
从句谓语表示状态时，通常用while。
2、引导地点状语从句的常用连词是where。
例如：Where there is a will there ia a way.3、引导原因状语从句的连接词主要有because, as, since, for。
2020届初三九年级英语中考考点41条件状语从句考点详解及专项练习跟踪训练题
考点四十一条件状语从句条件状语从句，即在某种条件下，一件事情可能发生。
在英语中由连接词if或unless等引导的状语从句叫作条件状语从句。
条件是指某一件事情实现之后（状语从句中），一件事情（主句）才能发生，通常译作＂假如，只要，如果＂等意思。
条件状语从句中，主从句的时态要遵循＂主将从现＂的原则。
即，主句是将来时态时，从句用一般现在时代替将来时态。
引导条件状语从句的连词或词组有：if(如果)，unless(除非)，as long as(只要)等。
如果主句是将来时，条件状语从句也用一般现在时来表示。
如：I will stay at home if it rains tomorrow. 如果明天下雨，我就待在家。
You can’t learn English well unless you work hard.除非你努力学习，否则是学不好英语的。
1.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。
If we pay much attention to the earth, we’ll have a better world.如果我们多关爱地球，就会拥有一个更美好的世界If it rains tomorrow, what shall we do? 如果明天下雨，我们怎么办？If you ask him, he will help you. 如果你请他帮忙，他会帮你的。
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。
注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去完成时。
What would happen if there were no water? 如果没有水会怎样？2. unless引导的条件状语从句unless的意思是＂如果不，除非＂。
可与if... not互换。
You will fail in English unless you work hard.你英语考试会不及格的，除非你更加努力。
2020年中考之宾语从句、定语从句、状语从句
2020年中考之宾语从句、定语从句、状语从句宾语从句考点1宾语从句的引导词1. I hope that your dreams will come true.我希望你们的梦想会实现。
◆陈述句(肯定句和否定句)作宾语从句，由that引导，且此类句子中that常可省略。
2. She wants to know if/ whether her uncle likes the new shirt.她想知道她的叔叔是否喜欢那件新衬衫。
I don't know whether or not this coat is yours.我不知道这件大衣是不是你的。
◆一般疑问句作宾语从句由if或whether引导，意为“是否”、“是不是”。
句中或句尾有or not时，只能用whether。
3.The small child doesn't know who Father Christmas is.4.这个小孩儿不知道圣诞老人是谁。
Could you tell me why you are late for school?你能告诉我你为什么上学迟到吗？◆特殊疑问句作宾语从句，由疑问代词who, whom, whose, what, which或者疑问副词when, where, how, why引导。
注意：主语是第一人称，谓语动词为believe, think, suppose, imagine 等，所带的宾语从句是否定句时，通常否定前移。
即：主句用否定形式，而宾语从句用肯定形式。
eg：I don't think that he likes dancing.我认为他不喜欢跳舞。
考点2 宾语从句的语序1. 宾语从句要用陈述语序。
2. 注意：对主语提问的特殊疑问句没有语序变化，因此疑问语序等于陈述语序。
eg：The boy broke the window.那个男孩打破了窗户。
→Who broke the window？谁打破了窗户？→I don't know who broke the window.我不知道是谁打破了窗户。
人教版2020届中考英语语法突破专题——《状语从句》 含解析
人教版2020届中考英语语法突破专题——《状语从句》状语从句从字面意思来理解就是句子的状语由一个从句充当，它通常用来修饰主句中的动词，形容词或副词所处的状态。
状语从句都由从属连词引导，与主句连接，放在句末时，一般不在前面加逗号，从句的意思是和主句一起，构成一个句子，若是两个句子，其中间必须用逗号。
（复习时可以考虑把连词和状语从句放在一起复习，因为两者有交集）状语从句根据它表示的意思可分为时间、原因、条件、目的、结果、让步、比较（中考基本不考）等。
下面我们拣重点的一个一个来分析。
时间状语从句：是由when, as, while, after, before, since, until, as soon as 等从属连词引导的状语从句。
时间状语从句中的谓语动词不能用一般将来时，只能用一般现在时表示将来发生的动作或存在的状态。
如:I will call you as soon as I arrive there.（记住一个口诀在时间状语从句中注意主将从现，即主句用将来时，从句用现在时，中考必考）原因状语从句：because, since, as和for都表示原因。
常常令我们不知该用哪个好。
我们来比较一下。
because语势最强，回答why提出的问题，用来说明人所不知的原因。
当能够很明显的看出原因或人们已知原因，就用as或since。
如：I don't like that coat,because the color looks terrible. 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。
如：He is not here, because / for his mother is ill.（与连词相关）条件状语从句：由if引导的条件状语从句。
if 意为“如果”，引导条件状语从句时，表示假如有从句的动作发生就(不)会有主句的动作发生。

状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。
根据其含义状语从句可分为时间状语从句、地点状语从句、条件状语从句、原因状语从句、结果状语从句、比较状语从句、目的状语从句，让步状语从句。
1.时间状语从句1)时间状语从句常用when as while before after since till until as soon as等连词来引导。
例如：It was raining hard（ rain hard 下大雨）when got to school yesterday.While he was doing his homework the telephone rang.As he walked along（沿着走）the lake he sang happily.He had learned a little Chinese before he came to China.After he finished middle school he went to work in a factory.2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。
例如：I’ll ring you up as soon as I get to New York.I will tell him everything when he comes back.He won’t believe it until he sees it with his own eyes.3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。
如果主句用否定式，其含义是“直到……才……”“在……以前不……”谓语动词可用瞬间动词。
例如：The young man read till the light went out（熄灭）.Let’s wait until the rain stops.We won’t start until Bob comes.Don’t get off（从下来）until the bus stops.【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。
Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止（不怎么可能持续）。
固定组合里from morning till night，till/until 是不能替换的，】2.条件状语从句1)条件状语从句通常由if unless引导。
例如：What shall we do if it snows tomorrow?Don’t leave the building unless I tell you to.2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。
例如：I’ll help you with your English if am free tomorrow.He won’t be late unless he is ill.3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。
例如：Hurry up or you’ll be late.=If you don’t hurry up you’ll be late.Study hard and you will pass the exam.=If you study hard you will pass the exam.3.原因状语从句1)原因状语从句通常由because since as引导。
例如：He didn’t come to school because he was ill.As it is raining we shall not （不得；不应该）go to the zoo.Since you can’t answer the question I’ll ask someone else.2)because表示直接原因，语气最强。
Because引导的原因状语从句多放在主句之后。
回答由why提出的问题，只能用because。
As和since语气较弱，一般用来表示明显的原因。
由as和since引导的原因状语从居多放在句首。
例如：-Why aren’t going there?-Because I don’t want to.As he has no car he can’t get there easily.Since we have no money we can’t buy it.3)because和so不能同用在一个句子里。
4.结果状语从句1)结果状语从句由so…that suc h…that so that引导。
例如：He is so poor that he can’t buy a bike for his son.She is such a good teacher that everybody likes her.My pencil fell under the desk so that I couldn’t see it.2)so…that语such...that可以互换。
例如：在由so...that引导的结果状语从句中，so是副词，与形容词连用。
其结构是: “...so+ 形容词（副词）+ that + 从句”。
例如：He was so glad that he couldn’t say a word.The hall is so big that it can hold 2000 people.Mother lives so far away that we hardly ever （几乎不，从来不）see her.在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词；名词前面可以带形容词，也可不带。
如果是单数可数名词，前面需加不定冠词a或an。
例如：It was such a hot day that nobody wanted to do anything.He had such long arms that he could almost touch the ceiling.（天花板）He made such rapid progress that he did very well in the mid-term.有时上述两种结构是可以互换的。
例如：It was such a wonderful film that all of us wanted to see it again.=The film was so wonderful that all of us wanted to see it again.It is such an important match that nobody wants to miss it.=The match is so important that nobody wants to miss it.3)如果名词前由many much little few等词修饰时，只能用so 不用such。
例如：Soon there were so many deer that they ate up all the wild roses.He has so little time that he can’t go to the cinema （去看电影）with you.5.比较状语从句比较状语从句通常由as…as比较级+ than…等连词引导。
例如：Tom runs faster than John does.This classroom is as big as that one.6.目的状语从句1)目的状语从句通常由so that in order that（为了，以便）引导。
例如：We started early so that we could catch the first train.He studies hard so that he could work better in the future.We used the computer in order that we might save time.2)so that既可引导目的状语从句，又可引导结果状语从句。
区别这两种从句的办法有两个：①目的状语从句里往往带有情态动词can could may might等。
②从意思上看，目的状语从句往往表示的目的很明确。
例如：Speak clearly so that they may understand you.(目的状语从句)Jack is badly ill so that he has to rest.(结果状语从句)7.让步状语从句1)让步状语从句通常由although though等连词引导。
例如：Though he is young he knows a lot. Although I am tired I must go on working.2)although(though)不能用在同一个句子中。
例如：我们不能说：Though it was raining hard but he still went out.应该说：Though it was raining hard he still went out.或It was raining hard but he still went out.8.地点状语从句地点状语从句常常由where来引导。
例如：Go where you like.Where there is a will there is a way.总结：状语从句分类及常用连词类别连词时间状语从句when whenever while as before after since till once（一旦）地点状语从句where wherever原因状语从句because since as for now that（既然，由于）etc. （et cetera，等于and so on）目的状语从句in order that(为了，以便) so that that etc.结果状语从句so…that so that such…that that etc.条件状语从句if unless as(so)long as etc.让步状语从句though although even if even though however whatever as etc.比较状语从句as…as so…as than etc.方式状语从句as as if as though etc.练习一一、单项填空1._______ he’s old he can still carry this heavy bag.A.
