高中英语状语从句用法详细解析
高中英语状语从句用法详细解析之袁州冬雪创作一、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，只起毗连作用，状语从句放在句首时，要用逗号，放在句尾时不必.二、分类根据意义上的分歧，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目标状语从句⑤条件状语从句⑥成果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句三、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, allthe lights went out.I was sleeping when she came in. 动补When we arrived at the station, the train had left.“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，常暗示较长的时间或一个过程.While we were having supper, all thelights 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，毗连并列分句.When暗示“就在……的时候”, while意反而，可是，暗示转折.One evening Beethoven was walking in a street, when he suddenly stopped outside a little house.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，从句用一般过去时暗示过去将来时，主句是一般过去时，从句用一般过去时.1. I' ll call you when I get there.2. They said they would leave when they got the new.3. They left as soon as they got the new.Whenever 无论什么时候，随时1. Whenever someone throws in some rubbish, the truck produces a piece of music.每当有人扔进一些渣滓时，它（汽车）就放一段音乐.2. Whenever we' re in trouble, they will help us.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.till和until(暗示“直到……”)句首多用until1、在必定句中暗示“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、在否定句中暗示“直到……才”主句谓语动词常常使用终止性动词，这时until和till常被before替换.I didn' t leave till/until she cameback.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.It is two years since I have studied English.1. We have known each other since we were children.2. We have been friends (ever since) since we met at school.3.

Maria has been in China since two years ago.*every time, each time, next timeEvery time you get back at night, you drop your boots on the floor.Every time I catch cold, I have pain in my back.(every time 分写不成以合写) 比较everyday (adj) 日常的，普通的every day 是名词短语，天天，天天Next time I go there, I will visit them.* once 一旦…就Onceyou begin, you must go on. 你一开了头，就应该继续下去.四、地点状语从句地点状语从句用where, wherever引导We should go where the people need us.我们应该去人平易近需要我们的地方.Where there is a will, there is a way. 有志者，事竟成.Wherever they went, they received a worm welcome. 无论他们走到哪儿都受到热烈欢迎.She follow him whose he goes. 他无论到哪里她总跟着.五、原因状语从句原因状语从句用because(因为)，since(既然), as(由于)引导1、字母由多到少，语气由强到弱.2、由why提问必须用because回答.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Because of the rain, we didn' t go to the park.4、 because 和so不成连用，只能选其一.（还有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 Smithwanted to give John a Chance.5、 for并列连词，不克不及放在句首，主要放在两个并列句之间.For所提供的来由为一个补偿说明，而且前面常有逗号隔开.The days we short, for it is December now.*改错 Because he is ill is the reason why he can' t come. (Because改为that)六、目标状语从句目标状语从句用so(常常使用于白话), that, so that, in order that引导目标状语从句的谓语常含有may, might, can, could, should, would等情态动词.1. We' ll sit never to the front so we can hear better.2. He studied hard so that he might succeed. 他尽力学习，以便成功.3. I' ll speak slowly so that you can take notes. 我渐渐讲，以便你们能做笔记.4.

高中英语语法系列：状语从句状语从句：状语从句主要用来修饰主句或主句的谓语。
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，方式状语从句，结果状语从句。
一.地点状语从句连接词：where,wherever,everywhere,anywhereEg.When you read the book,you'd better make a mark where you have any questions.Wherever you are,whatever you do,I will be right here waiting for you. Wherever you work,you will gain much valuable experience as long as you are willing to work.Everywhere they went,they were warmly received.独特用法：Where—不能翻译成“在……地方”时，通常翻译成“如果”，表示在……条件下。
Eg.有志者，事竟成。
Where you are confident,you will succeed.二.原因状语从句连接词：because,since,as,for,now that,in that,seeing that,considering that, given that,considering that比较：because,since,as和for(1)because语势最强，用来说明人所不知道的原因，回答why提出的问题。
当原因是显而易见的或已为人们所知，就用since或asEg.Mr.Zhang disliked me because I'm handsome and rich.Since/As the weather is so bad,we have to delay our journey.(2)由because引导的从句如果放在句末，且前面有逗号，则可用for代替。
但如果不是说明直接原因，而是多种情况加以判断，就只能用for.Eg.He is absent today,because/for he is ill.He must be ill,for he is absent today.now that：“既然”in that：“因为”，通常只能放于句中，强调重要的、唯一的原因。
Eg.Now that everybody has come,let's begin our conference.Human beings are different from animals in that humans can speak and think. Considering that he is no more than12years old,his height of1.80m is quite remarkable.owing to,due to,thanks to,as a result of属于连词短语，后面只能接词或短语，不能接从句。
三.条件状语从句连接词：if,unless,as/so long as,only if,providing/provided that,suppose that,in case that,on condition that注意：①如果引导的条件可以实现，则“主将从现”；②如果引导的条件和事实相反，则用虚拟语气。
Eg.She will sing a song if she is asked.If I were a bird,I would fly.As long as it doesn't rain,we can play.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?You will miss the train unless you hurry up.=You'll miss the train if you don't hurry up.“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。
e your head,then you'll find a way.=If you use your head,you'll find a way. Study hard and you will pass the exam.=If you study hard,you will pass the exam. without与条件句的转化Eg.Man can't live without water.=Man can't live if there is no water.if only：只要eg.He will succeed if only he does his best.only if：只有eg.Only if you are here,we have confidence.四.时间状语从句连接词：when,as,while,as soon as,while,before,after,since,till,until，the minute,the moment,the second,every time,the day，the instant,immediately, directly,no sooner…than,hardly…when,scarcely…whenEg.I didn't realize how special my mother was until I became an adult.While John was watching TV,his wife was cooking.The children ran away from the orchard(果园)the moment they saw the guard.No sooner had I arrived home than it began to rain.Every time I listen to your advice,I get into trouble.基本用法：(1)当……时候：when,while,asEg.I'll tell her the good news when he comes back.While my husband is cooking I am watching TV.As time went by,the days became shorter and shorter.(2)一……就……：as soon as,directly,immediately,instantly连接两个句子；一些名词如the minute,the moment,the instant也可表示；Eg.I'll let you know as soon as he comes back.I'll write to you the moment/minute I arrive in Paris.注意：scarcely...when表示当……时候；no sooner...than,hardly...when主句谓语动词一般要用过去完成时，从句谓语动词要用一般过去时(否定词在句首，后面的句子需要部分倒装)Eg.Hardly had he seen me when he ran away.他一看见我就跑了。
No sooner had they reached home than it rained more and more heavily.他们一到家，雨就越下越大起来。
Scarcely was George Washington in his teens when his father died.(3)直到......：till/until①肯定形式表示的意思是“做某事直至某时”，动词必须是延续性动词；否定形式表达的意思是“直至某时才做某事”，一般用until，动词为延续性或非延续性动词都可以。
Eg.I'll stay here until everyone else comes back.Wait till I call you.I did n't manage it until you had explained how.②until可用于句首和句中，而till通常不用于句首。
Eg.Until you told me,I had heard nothing of what happened.=I had heard nothing of what happened until you told me.注意：not...until的四种不同句式—a.正常句式：We didn't go home until we finished our work.b.until在句首：Until we finished our homework,we didn’t go home.c.倒装句式：Not until we finished our homework did we go home.d.强调句式：It is not until we finished our homework that we went home.五.结果状语从句常用连接词：so…that,such…that,so that...1.so that的用法：so that引导结果状语从句时意为“以致；以至于”，从句前有时用逗号与主句分开。
