高中英语状语从句知识点及练习
高中英语---状语从句
一、概念：状语通常由副词、介词短语、动词不定式、分词和从句等担当。
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，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。
二、分类及使用
1.时间状语从句
(1)when ①.when引导的时间状语从句，其动词既可以是延续性动作的动词，也可以是瞬间性动作的动词，可以表示主句的动作和从句的动作同时发生，或从句的动作发生在主句的动作之前。whenyouapplyforajob,youmustpresentyourcredentials.
②when还可表示justthen（正在那时）的意思，此时所引导的从句放在主句之后。wewereabouttostartwhenitbegantorain.
(2)as引导的时间状语从句as侧重表示主句和从句的动作并相发生,翻译成一边，一边。Wewerehavingbreakfastasshewascombingherhair.
(3)while “在…期间”，所引导的从句的动作是延续性的，并表示和主句的动作同时发生。
(4)before引导①before“在…之前”I’llbebackbeforeyouhaveleft.
②before“…之后才”Itmaybemanyyearsbeforewemeetagain.
(5)assoonas/once/directly/theinstant等引导
assoonas是最常见的表示“一…就”的从属连词，其他连词还有immediately，instantly，theinstant(that)，theminute(that)，themoment(that)等，它们通常都可与assoonas换用。Assoonaswegothome,thetelephonerang.
IrecognizedherimmediatelyIsawher.
(6)hardly...when/nosooner...than引导
关联从属连词hardly/barely/scarcely...when和nosooner...than的意思是“刚…就”，它们所引导的从句中的谓语动词通常为过去完成时。如：
Hehadnosooner(nosoonerhadhe)arrivedhomethanhewasaskedtostartonanotherjourney.
(7)since引导
在含有since引导的时间状语从句的复合句中，从句的谓语动词通常为一般过去时，主句的谓语动词通常为现在完成时、过去完成时和一般现在时：
We’venevermetsincewegraduatedfromthecollege.大学毕业后我们就再没见过面。
(8)till/until引导till和until同义，作“直到…时(为止)”解。Donaldwillremainincollegeuntil(till)hefinisheshisPh.Dcourse.
2.地点状语从句
(1)where引导“在（或到）…的地方”
Wherethereisawill,thereisaway.
(2)wherever引导wherever=nomatterwhere,后者只能放句首。
Whereever(nomatterwhere)theywent,theexpertswerewarmlywelcomed.
3.原因状语从句
(1)because引导通常用于回答why引出的疑问句，从句一般位于主句后面。
Ididn’tgoabroadwithherbecauseIcouldn’taffordit.

AsIdidn’tknowtheway，Iaskedapoliceman.
(3)since引导从句多位于主句之前，可以和as换用。
Sincetravelingbyairismuchfaster,theydecidedtotakeaplane.
(4)now(that)引导的原因状语从句now(that)“既然”，
Now(that)youhavepassedyourtestyoucandriveonyourown.
(5)seeing(that)引导的原因状语从句Seeing(that)“鉴于；由于”，通常用于非正式文体。Seeing(that)theweatherisbad，we’llstayathome.
4.目的状语从句
(1)inorderthat引导“为了；以便”。多用于正式文体，可以与sothat换用。TheystoppedatHangzhouinorderthattheycouldgoaroundWestLake.
(2)so(that)引导“为了；以便”。sothat通常可以与inorderthat换用，它所引导的目的状语从句总是放在主句之后，在非正式文体中，常省略that。如：Speakclearlysothattheymayunderstandyou.
(3)incase/forfear(that)等引导
incase，forfear(that)这俩个从属连词都表示否定目的，意思是“以免”,“以防”。incase它所引导的从句中的谓语动词可以是陈述语气形式，也可以是虚拟语气形式；forfear(that)引导的从句中的谓语带有may，might，should等情态动词
Takeyourumbrellaincaseitrains.
Hetookanumbrellawithhimforfearthatitmightrain.
5.结果状语从句
(1)sothat引导从句只能位于主句之后，sothat引导什么从句根据句意来判断Suddenlyitbegantorainheavily, sothatitwasalmostimpossibletocarryondriving.
(2)so...that引导“如此…以致”，that可以省略，so后面接形容词或副词。Shespokesofastthatnobodycouldcatchwhatshewassaying.
(3)such...that引导的结果状语从句
引导结果状语从句的such...that的具体内容是：such+a/an+形容词+名词+that从句。
such+a/an+形容词+单数名词+that=so+形容词+a/an+单数名词+that从句。Theprofessortoldussuchafunnystorythatallthestudentslaughed．
=Theprofessortoldussofunnyastorythatallthestudentslaughed.
6.条件状语从句
(1)if引导译成“如果”

(4)as/solongas引导意为“只要；如果”。

8.方式状语从句
(1)as引导意为“以…方式；如同…那样”，从句有时是省略句。Airistomanaswateristofish.
(2)asif/asthough引导作“好像，仿佛”解。从句往往用虚拟语气，表示与事实相反。Theylookedatmeasif/asthoughIweremad.
9.比较状语从句

高中英语状语从句讲解汇总
高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。

高中英语语法状语从句归纳总结
状语从句一． 二．分类：
adv.+that （如此……以致） so that （结果……） such+n.+that （如果……以致） that （所以，因此） 让步状语从句： though/although 不可同but 连用。 though/although （虽然） however （可是） even though/if （即使） no matter+what/which/where/who/when =whatever/whichever/wherever/whoever/whenever （不论什么/哪一个/哪里/谁/何时） 比较状语从句： as （正如） as…as （和……一样） not as/so … as （不如……） than （比……更） the+比较级…+the+比较级 （越……越……） 条件状语从句： if （假设） unless （如果不） so long as （只要） on condition that （如果） 方式状语从句： as （像……那样地） just as （正像） as if （好像） as though （好像） 三． 四． 各种状语从句的简化方法：
1． 2．以after和before引导的状语从句的主语若与主句主语一致时，从句等于after/before+doing sth. 作状语。 例：After she sang，she left the rich man's house．= After singing，she left the rich man's house．3． 4．以as soon as引导的状语从句的主语若与主句主语一致时，从句等于on+doing sth.,作状语，此时的动词为非延续性动词。 例：Mary began to operate on the wounded soldiers as soon as he arrived at the village． = Mary began to operate on the wounded soldiers on arriving at the village． 5． 6．时间状语从句和条件状语从句的主语和主句主语一致时，有时可简化为不定式作状语。 例：She stopped when she saw her husband．= She stopped to see her husband． If you want to understand the farmers，you must go to the countryside． = To understand the farmers，you must go to the countryside． 7． 8．结果状语从句和目的状语从句的主语与主句主语一致时，可以简化为不定式作状语；若两者主语不一致时，则应简化为不定式的复合结构作状语。 例：He was so tired that he couldn't go any further．= He was too tired to go any further． I came here so that I could ask some questions．= I came here(in order) to ask some questions．9． 10．以when，while引导的时间状语从句和以if引导的条件状语从句的主语若与主句主语一致时，从句等于when/while/if +doing sth.作状语，表示谓语动作发生在该状语动作的进行过程之中。例：When he turned on the radio，he found it broken．= When turning on the radio，he found it broken．While she was walking along the street，she was hit by a car．= While walking along the street，she was hit by a car． 11．原因状语从句的主语与主句主语一致时，可简化为分词短语作状语。 例：Since l didn't know Chinese，I tried to speak to her in English．= Not knowing Chinese，I tried to speak to her in English． 注意：形容词短语也可作表示原因的状语，来代替原因状语从句，放在句首、句末均可，但一般应加逗号。 例：As he was thirsty and eager to get a little rest，he went into the tea-house． = Thirsty and eager to get a little rest，he went into the tea-house． 12．在时间、原因、条件等状语从句中，若从句和主句主语不一致时，可简化为分词复合结构作状语。有时也可简化为“with/without名词或代词十分词(短语)”形式作状语。 例：When the film start appeared, the children got exited．= The film start appearing，the children got exited． If all the work is done, you can have a rest．= With all the work done，you can have a rest． Nothing can live if there is no air．= Nothing can live without air．
(完整word版)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 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，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。 二、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 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 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。

专题十一状语从句 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。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...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, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time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 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。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 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。
