高中英语状语从句学案(9种全)状语从句在复合句中作状语的从句叫状语从句。
状语从句有时间、地点、原因、目的、结果、条件、方式、比较、让步等种类。
一、时间状语从句引导时间状语从句的连接词有: when,as,while,after,before,since,ever since,as soon as,once,till,until,whenever,no sooner…than,hardly/scarcely...when,the moment/minute/instant/second,every time,each time,any time,the first time,next time,last time,all the time,by the time,directly,immediately,instantly等。
1.表示“一···就···”的句型1) as soon as/onceAs soon as he arrives,I'll call you.他一到,我就给你打电话。
(as soon as 侧重时间或动作先后衔接紧,而once侧重条件,表示“一旦...”)2) on doing sth/on one's + n.作时间状语On arriving at the station,the thief was arrested.一到达车站,这个小偷就被逮捕了。
On his arrival in Paris,he was recognized as a noble and thrown into prison. 他一到达巴黎,就被认出是一个贵族,并被投入监狱。
3) no sooner ...than ,hardly/scarcely...when它们表“一…就”。
结构中的否定词放在句首时,主句要倒装。
(主句都用过去完成时,从句用一般过去时。
状语从句一、两点提示:1.时间、条件状语从句中谓语动词常用的时态:主将从现2.when, while, as, if, though, as if, once可以引导从句,也可以通过省略表达,直接跟分词e.g. When they were first introduced to the market, these products enjoyed great success.=Although he was told to stop, he kept on working.=c.f. before 和after 用法不同,要么引导从句,要么跟名词或动名词作宾语二、具体注意点:时间状语从句1.when引导的从句谓语动词可以是延续性动词,也可以是瞬间动词;从句动作可以和主句动作同时发生,也可以先于主句动作发生。
while引导的从句谓语动词必须是延续性动词,强调主从句动作或状态是同时发生或存在的。
as有时可以和when, while通用,但强调两种正在发展和变化的情况时,只能用ase.g. 随着日子的流逝,天气变得越发糟糕。
2.when = just at that time, 连接两个并列分句,只能位于句子的后半部分注意时态:was/ were about to do sth. when…was/ were doing sth. when…had just done sth. when…e.g. 他正要告诉我这个秘密,这时有人拍了拍他的肩膀。
3.no sooner…than…=hardly / barely / scarcely…when…刚。
就。
注意:(1)连词搭配(2)时态运用(3)否定表达位于句首时引起部分倒装e.g. 他刚刚坐下,电话铃响了。
4.Not until…主句倒装从句不倒装It was not until…that…强调句中主从句都不倒装,且只能用not until,不能用untile.g. 直到他摘下墨镜我才认出她是位著名影星。

二、复习预习定义: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。
状语从句一般分为九大类: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三、知识讲解知识点1 :时间状语从句一、由when, while, ,as引导的时间状语从句。
例如:When you think you know nothing, then you begin to know something.(当你以为自己一无所知的时候,你就是在开始知道一些事物了。
)Strike while the iron is hot. (趁热打铁。
)You can feel the air moving as your hand pushes through it.( 当你的手在空气中挥动的时候,你就能感觉到空气在流动。
) 注意:when, while和as的区别1、when引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。
并且when有时表示“就在那时”。
例如:When she came in, I stopped eating.她进来时,我停止吃饭。
(瞬时动词)2、While引导的从句的谓语动作必须是延续性的,并强调主句和从句的动作同时发生(或者相对应)。
并且while有时还可以表示对比。
3、As表示“一边……一边”,as引导的动作是延续性的动作,一般用于主句和从句动作同时发生;as也可以强调“一先一后。
二、由before和after引导的时间状语从句。
注意before引导的从句不再用否定式的谓语,并且当before引导的从句位于主句之后,有时译成“就,才”。
还要注意主句和从句之间的时间关系。
当主句用将来时,从句总是用现在时;如果before引导的主句谓语用的是过去完成时,则从句动词多用一般过去时,这样以便体现动作发生的先后。
After表示主句动作发生在从句动作之后。
主句和从句的动作的时间关系正好与before引导的从句相反。
例如:It will be four days before they come back. 他们要过四天才能回来。
Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我。
三、由till或until引导的时间状语从句。
till和until一般情况下两者可以互换,但是在强调句型中多用until。
并且要注意的是:如果主句中的谓语动词是瞬时动词时,必须用否定形式;如果主句中的谓语动词是延续性动词时,用肯定或否定形式都可以,但表达的意思不同。
till不可以用在句首,而until可以放在句首。
例如:I didn't go to bed until(till)my father came back.直到我父亲回来我才上床睡觉。
It was not until the meeting was over that he began to teach me English.直到散会之后他才开始教我英语。
四、由since引导的时间状语从句。
since引导的从句的谓语动词可以是延续性的动词,又可以是瞬时动词。
一般情况下,从句谓语动词用一般过去时,而主句的谓语动词用现在完成时。
但在It is +时间+since从句的句型中,主句多用一般现在时。
例如:I have been in Beijing since you left. 自从你离开以来,我一直在北京了。
Where have you been since I last saw you? 自上次我和你见面以后,你到哪里去了?It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。
五、由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。
这些连词都表示“一……就”。
例如:I will go there directly I have finished my breakfast. 吃完早饭,我立即到那里去。
The moment I heard the news, I hastened to the spot.我一听到消息,马上赶到了出事地点。
As soon as I reach Canada, I will ring you up. 我一到加拿大,就给你来电话。
注意:hardly (scarcely, rarely)…when / before,no sooner…than相当于as soon as之意。
主句用过去完成时,从句用一般过去时。
当hardly, scarcely, rarely和no sooner位于句首时,主句应用倒装语序。
例如:He had no sooner arrived home than he was asked to start on another journey. 他刚到家,就被邀请开始另一旅程。
六、由by the time引导的时间状语从句。
注意时态的变化:在一般情况下,如果从句的谓语动词用一般过去时,主句的谓语动词用过去完成时;如果从句的谓语动词用一般现在时,主句的谓语动词用将来完成时。
例如:By the time you came back, I had finished this book.到你回来时,我已经写完这本书了。
By the time you come here tomorrow, I will have finished this work. 你明天来这儿的时候,我将已经完成此工作了。
知识点2 :原因状语从句连接词because, for, as, since1)because表示提问者不知道的原因,若用why提问,只能用because来回答——Why are you absent from the meeting? ——Because I am ill.My friends dislike me because I'm handsome and successful.2)for表示推测而出的原因It rained last night, for the ground is wet this morning.3)as表示说话双方都知道的原因As Sunday is a national holiday, all government offices will be closed.4)since表示既然Since we don't have class tomorrow, why not go out for a picnic.知识点3 :地点状语从句常常由where来引导。
