高考英语重要语法知识：状语从句

高考英语重要语法知识：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。

分类：根据意义上的不同，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目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句一、时间状语从句引导时间状语从句的连词有：as, when(whenever),while, before, after, as soon as, until(till), since,every/each/next time, once.（ as, when, while都有“当……的时候”，可以互用）◆When、While、as的区别：①when是at or during the time ,既指时间点，也可指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词；while是during the time,只指一段时间，所以while从句中的动词必须是延续性动词。

②when说明从句的动作和主句的动作可以是同时，也可以是先后发生；when从句多用一般过去时while主从句动作或状态同时发生。

while从句多用过去进行时eg. When the teacher came in,we_____________________(talk).When the clock struck twelve,all the lights went out.When we arrived at the station,the train had left.While we _____________(have)supper,all the lights went out.While I was writing letters last night,he was watching TV.④when和while还可作并列连词when表示“就在那时”； while表示“然而”，表前后意思的对比。

状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。
1. 时间状语从句常见的连词(组)：
when, while, as, before, after, once, till, until, as soon as, n, scarcely ...when, no sooner ...than等。
It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ② 不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③ 刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。 ④ 先……再…… You can have a few days to think about it before you make your decision. 做决定之前你还有几天时间考虑。
注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。

sner than等可以引导时间状语从句的副（介）词（短语）或名词短语：directly, instantly, iediately, by the tie, the ent, the secnd, the inute, the instant, every tie, each tie, net tie, the last tie等注意点如下：(1) when, while, as引导的时间状语从句as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生when(at r during the tie)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a perid f tie时，两者可以互换She cae up as I was cing(同时)在我做饭时，她走了过When we were at schl, we went t the library every day(在一段时间内)当我们在学校时，每天都去图书馆While they were watching TV, I was preparing yself fr the cing eainatin他们在看电视，而我在为即将到的考试做准备Strie while the irn is ht 趁热打铁( 不可用as或when，这里的while意思是“趁……”)一、when可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用① Why d yu want a new jb when yu've gt such a gd ne already？（get为短暂性动词）你已经找到如此好的工作，为何还想再找新的？②Srry，I was ut when yu called e．（call为短暂性动词）对不起，你打电话时我刚好外出了③Strie while the irn is ht．（is为延续性动词，表示一种持续的状态）趁热打铁④ The students t ntes as they listened．（listen为延续性动词）学生们边听课边做笔记二、when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生1．从句动作在主句动作前发生，只用 when①When he had finished his hewr，he t a shrt rest．（finished先发生）当他完成作业后，他休息了一会儿②When I gt t the airprt，the guests had left．（gt t后发生）当我赶到飞机场时，客人们已经离开了2．从句动作和主句动作同时发生，且从句动作为延续性动词时，when，while，as都可使用①When ／While ／As we were dancing，a stranger cae in．（dance为延续性动词）当我们跳舞时，一位陌生人走了进②When ／While ／As she was aing a phnecall，I was writing a letter．（ae为延续性动词）当她在打电话时，我正在写信3．当主句、从句动作同时进行，从句动作的时间概念淡化，而主要表示主句动作发生的背景或条件时，只能用 as这时，as常表示“随着……”；“一边……，一边……”之意① As the tie went n，the weather gt wrse．（as表示“随着……”之意）② The atsphere gets thinner and thinner as the height increases．随着高度的增加，大气越越稀薄③As years g by，hina is getting strnger and richer．随着时间一年一年过去，中国变得越越富强了④The little girls sang as they went．小姑娘们一边走，一边唱⑤The sad ther sat n the radside，shuting as she was crying．伤心的妈妈坐在路边，边哭边叫4．在将时从句中，常用when，且从句须用一般时代替将时①Yu shall brrw the b when I have finished reading it．在我读完这本书后，你可以借阅②When the anager ces here fr a visit net wee，I'll tal with hi abut this．下周，经理这参观时，我会和他谈谈此事三、when用于表示“一……就……”的句型中（指过去的事情）sb．had hardly（＝scarcely） dne sth．when．．．＝Hardly ／ Scarcely had sb．dne sth．when．．．①I had hardly ／scarcely clsed y eyes when sene nced at the dr．＝Hardly ／ Scarcely had I clsed y eyes when sene nced at the dr．我刚一闭上眼，就有人在敲门了②I had hardly ／scarcely entered y r when the telephne rang．＝Hardly

telephne ring他刚进屋电话铃就响了④先……再……Yu can have a few days t thin abut it befre yu ae yur decisin做决定之前你还有几天时间考虑(3)since 引导的从句用延续性动词的过去式（包括过去完成时）时，则从句的动作已经结束,从句意思是否定的如果从句的动词是延续性动词的现在完成时态，则从句意思是肯定的He has never been t see e since I was ill我病愈后，他一直未看我（不再生病了）He has never been t see e since I have been ill我病了，他一直未看我I haven t heard fr hi since he lived here自他从这里搬走，我就没有收到他的信（不住在这儿了）(4) till, until如果till与until用在肯定句中时，则主句中谓语动词部分所表示的动作或状态一直延续到某时或某个动作发生时才结束注意它的倒装句和强调句I didn t recgnize she was y classate until she t ff her dar glasses=Nt until she t ff her dar glasses did I recgnise she was y

that(鉴于……)注意以下几点：(1) because, since, as, fr, nw thatbecause语气最强，用于回答why的提问，可与强调词nly, just 以及否定词nt 连用但不可以与s连用since 引导的从句语气次于because引导的从句，常表示稍加分析后而推断出的原因，或指人们已知的事实，比as正式一些,常置于句首as 语气最弱，其原因只是对结果的附带说明，一般放在句首fr虽然解释为“因为”但只是一个并列连词，它也常引导句子表示原因，但不是原因状语从句，它是一个并列句fr所提供的理由是一种补充性的说明，表示推测的理由nw that意为“既然，由于”表示由于人们已知的事实或正在发生的事而产生某个结果He failed because he was careless他因粗心而失败了Since everyne has ce, let s begin ur eeting既然大家都了，我们开会吧As all the seats were full, he std there所有的座位都满了,他只好站那儿It ight have rained last night fr the grund is wet昨晚可能下雨了，因为地面是湿的Nw that the ids have left he we have a lt f

高考英语语法复习：八种状语从句的用法

高考英语语法复习：八种状语从句的用法状语从句状语从句有时间、地点、原因、目的、方式、结果、条件、让步等八种。

一、时间状语从句：引导词有after，before，as，once，since，till，until，when，whenever，while，as soon as，the moment/minute…(一…就)，the time,the day,every time,next time,each time，by the time of，no sooner…than(一…就)，ha rdly…when(一…就).例如：Each/Every time he comes here,he will drop in on me.每次他来这儿他都顺便看我.He was ill last time I saw him.上次我见到他时他病了.No sooner had she heard the news than she cried.她一听到这个消息就哭了.[辨析]when与whilewhen引导的从句动词可以是延续性的或短暂性的，while引导的从句中动词必须是延续性的;在“be…when…”句式中when表“at that time(就在这时)”意，这样用的when不能换为while;while有时并不表示时间，而表示对比，意“而”、“却”，when无这样的用法。

例如：When I got home I found the door locked./While(或When)we were working in the fields,it suddenly began to rain./He was wandering through the streets when a bike hit him./His pencil is red,while mine is yellow.[辨析]till与until一般情况下可以互换，但until可以位于句首，till则不能。

高考英语第十四章状语从句知识精讲

状语从句【知识精讲】状语从句,也叫做副词性分句，在主从复合句中起到状语作用，即把句子当作状语来使用，其作用类似副词，有时甚至可以用副词代替。

用以修饰主句的动词，形容词或副词，非限定动词〔不定式，-ing或 -ed分词〕或修饰整个句子。

表示时间，地点，方式，程度，原因，结果，目的，条件，让步和比拟等。

在高考英语中，状语从句主要出现在单句选择，改错或完型填空中。

一、状语从句的含义和类别1. 时间状语从句引导时间状语从句的连词主要有：when, as, while, as soon as, while; before, after, since, till, until; the minute, the moment, the second, any time, the day，the week, the instant, every time, each time, (the) next time,(the) last time, the first time; immediately , directly; no sooner...than, hardly...when, scarcely...when等。

〔1〕表示“当……时候〞或“每当〞的时间连词。

主要的 when, while, as, whenever。

例如：●He jumped up when the phone rang. 当响起的时候，他站起来了。

●We listened while the teacher read. 教师讲，我们听。

●They sang as they danced. 他们边唱边跳。

【注意】在高考中，我们主要要注意when表示“突然〞性，常用于“be+doing...when...〞，“be about to do...when...〞，“be on the point of doing...when...〞，“had just done...when...〞等句型中。

高考英语状语从句的用法归纳

高考英语状语从句的用法归纳一、概说状语从句即指在主从复合句用作状语的从句。

按照其意义，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、目的状语从句、结果状语从句、条件状语从句、让步状语从句等。

状语从句是高中英语学习中的一个语法重点，也是历年高考重点考查的内容之一。

学习状语从句主要应注意引导状语从句的从属连词的用法与区别，以及从属连词在一定的语言环境中的意义与用法。

二、时间状语从句1. 引导时间状语从句的从属连词很多，常见的有before, after, when, while, as, since, till, until, as soon as 等。

2. 表示“当…时候”的 while, when, as 的用法区别是：while从句中的谓语动词必须是延续性动词；表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时，只能用 when；当表示“一边…一边…”或“随着”时，只能用 as。

另外，用于此义的 as 所引导的时间状语从句谓语只能是动作动词，不能是状态动词。

如下面一道高考题的答案是 B 而不能是A：“I’m going to the post office.” “_____ you’re there, can you get me some stamps?”A. AsB. WhileC. BecauseD. If3. until 在肯定句中通常只连用延续性动词，表示相应动作结束的时间；在否定句中通常连用非延续性动词，表示相应动作开始的时间，意为“直到…才”。

如：He waited until she was about to leave. 他等着一直到她准备离开。

I did not begin to work till he had gone. 他走了后我才开始工作。

4. 表示“一…就”除用 as soon as 外，还可用 the minute, the second, the instant, immediately, directly, instantly, no sooner…than, hardly…when 等。

副词、形容词、介词短语、非谓语以及句子等均可做状语。

用句子充当的状语就是状语从句。

表时间为时间状语从句，地点、原因等构成相应的从句。

Every day, he studied hard in this room through the computer in order to learn English well.When he was young, he studied English hard where he lived through the computer in order that he could learn English well.特殊规定在时间、条件、让步、方式状语从句中，用一般现在时态代替将来时态，用现在完成时态代替将来完成时态。

高考英语语法专题汇总：状语从句(附练习及答案)状语从句在句中作状语，可分为：时间、条件、让步、原因、目的、结果、地点、比较、方式状语从句。

1时间状语从句引导时间状语从句的连词有：when, as, while, until, not…until, before, after, since, the minute, the moment, each( every, next, the first) time 等。

时间状语从句中一般用一般现在时或一般过去时。

1．when , while, as都可解释为“当```的时候”但侧重点有所不同。

1) When后既可以接短暂性动词，也可以接延续性动词，表示从句动作与主句动作同时发生。

When I arrived home , I had a little rest.2）As 除了表示“当```的时候”，还可表示为“一面```一面”，“随着”He sang as he danced.(一面```一面) You will grow wiser as you grow older.(随着)3)While表示“当```的时候”强调主句的动作和从句的动作同时发生，从句一般用进行时，从句动词必须是延续性动词。

While we were working, they were having a rest.While (they were) having a discussion, they got very confused.注意：while 有对比的含义，解释为“然而”。

eg: I prefer black tee, while he likes coffee.2．until, not…until表示“直到`才”,在肯定句中主句常用延续性动词；在否定句中常用短暂性动词。

肯定句：I waited until midnight. 否定句：I did not leave until midnight. 注意点：1）not until…在句首，主句用倒装 Not until you had explained how did I manage to do it.2) It is not until…that…引导的强调句 It was not until it was dark that he came back.3．Hardly/scarcely…when, no sooner…than, as soon as表示为“一```就```”I had hardly/scarcely got home when it began to rain.I had no sooner got home than it began to rain. It began to rain as soon as I got home.2条件状语从句条件状语从句分为两大类：真实条件句（主将从现）和虚拟条件句（虚拟语气）。
