时间/地点/条件/让步/原因/结果状语从句讲解2022届高考英语语法总复习时间状语从句状语是在句子中修饰动词、形容词、副词等的句子成分,用于表达时间、地点、原因、目的、结果、条件、让步、方式、比较的句子成分。
每一种状语从句都有相对应的引导词如:时间引导词: when, whenever, while, since, as, until, once, as soon as等。
He was pretty ambitious when he was young. 在他年轻的时候,他相当有野心。
Whenever I come to this park, it would remind me of my carefree childhood.(每当我来到这个公园,我都会回忆起我无忧无虑的童年。

(既表示动作同时进行,也形成鲜明对比。
)As the day went on, the weather got worse. (随着时间天气变得更糟了。
)since引导的时间状语有一个特殊的点需要指出,先看例句:It is five years since I smoked.应翻译为:我戒烟已经五年了。
(It is +时间段+since 后所接动词是延续性动词表示时间从该动作结束那一刻开始)。
I have smoked for five years.我已经吸烟五年了。

外研版高二英语必修5 Module 5 语法指导:状语从句重难点讲解及练习含答案
状语从句重难点讲解本模块中我们复习了时间状语从句、条件状语从句和让步状语从句。
下面我们来看看这三种从句中需要注意的几点。
时间状语从句1. before / since“It be + 一段时间+ before ...”结构,在肯定句中常译为“多久之后才……”;在否定句中常译为“不久之后就……”。
如:It will be three years before he graduates from university.It was not long before he found another job.“It is / has been + 一段时间+ since ...”结构中, since从句的谓语动词多用一般过去时,表示动作或状态的完成,计时的起点是动作或状态完成的那一时刻。
在语义上,从句动词为延续性动词时,含有否定的意味;从句动词为非延续性动词时,含有肯定的意味。
如:It is 3 years since he were here. (表示“他不在这儿已经3年了”)It is 3 years since he stopped smoking. (表示“他不抽烟已经3年了”)2. when / as / while表示“当……时”,when引导的从句的动作和主句的动作可以同时发生,也可先后发生,从句中的动词既可以是延续性的,也可以是非延续性的;as,while 引导的从句强调主句和从句的动作同时发生,并且从句中的动词通常是延续性的。
如:When I lived there, I used to go to the seashore on Sundays.While you were reading the paper, I was working.As the kids walked home, they sang happily.注意:当从句表示“随着”时,连词只能用as。
如:As the day went on, the weather got worse.3. till / until两者都表示“一直到……;直到……才”,基本上可以互换,但till一般不位于句首。
高一语法:让步状语从句
让步状语从句的时态问题 特别关注: C me company, I will 1. Although nobody ______ go there alone. A. keeping B. has kept C. keeps D. will keep
在让步状语从句(以及时间、条件状语 从句)中,用一般现在时表示一般将来时, 即“主将从现”。
让步状语从句的语序问题
The parents will wait for him for dinner, although/ though he comes back late. No matter how/ However late he comes back, the parents will wait for him for dinner.
although/ though
Although/ Though he was old, he worked hard. = He was old but he worked hard.
注意一个典型的中式英语错误:although/ though 切不可与but连用!但可用yet, still。
改错:Although it rained heavily, but they still went out.
让步状语从句与并列句的区别 即学即练: A he works as 1. Though he is in his sixties, ______ hard as a young man A. yet B. but C. and D. and yet C I have some 2. Excuse me for breaking in, ______ news for you. A. so B. and C. but D. yet 题1是主从复合句,所以中间不能使用并列连词 and/or/
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),hardly…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。

Section ⅡGrammar时间、条件和让步状语从句时间、条件和让步状语从句在高考中约占3分,考查形式主要有单选、完型填空、语篇填空和改错,主要考察这三种从句中的引导词、谓语动词。
幻灯片3一、时间状语从句1.no sooner...than与hardly...when都表示主句与从句的动作相继发生,意为“一……就……,刚刚……就”,主句动词用过去完成时。
如no sooner,hardly位于句首时,主句用倒装形式。
He had hardly gone to bed when the doorbell rang.=Hardly had he gone to bed when the doorbell rang.他刚睡下门铃就响了。
No sooner had he got off the train than his daughter ran towards him.他刚下火车,他女儿就向他跑了过来。
幻灯片42.as soon as,the moment,immediately引导的从句表示从句动作一发生,主句动作随即发生,常译为“一……就”。
名词词组the second,the minute,the moment,every time,any time,next time,the first/last time,the day/week/month等亦可作连词,引导时间状语从句。
They told me about it as soon as/immediately/the moment they got themessage.他们一听到口信就把消息告诉了我。
Every time he walked by the lake,he thought of his childhood life.每当他走过那个湖时,就会想起童年的生活。
注意:immediately可用做连词也可用做副词。
幻灯片53.till和until词义是“直到……,一直……为止”,表示一个动作持续到某一时刻或某一动作发生为止,在句首只能用until。

语法解读-状语从句用法全解一、定义状语从句在句中作状语,修饰主句中的动词、形容词或副词等,有时修饰整个主句。
状语从句放在主句之前时,常用逗号分开;放在主句之后,一般不用逗号。
二、分类状语从句按其意义和作用可分为时间、条件、原因、让步、目的、结果、方式、比较、地点状语从句。
1.时间状语从句①时间状语从句常用的连词有when, as, while, before, after, since, till(until),once, as soon as, hardly...when.., no sooner...than, the moment等。
②时间状语从句中通常用一般现在时表示将来。
如:I’ll go on with the work when I come back tomorrow.明天我回来后接着干这个工作。
③连词when, while, as都表示“当……时候”,但是when引导的从句的动作和主句的动作可以同时发生,也可以先后发生;用as, while时则强调主句和从句的动作同时发生。
as和when可指时间的某个点,也可指一段时间,但while不可以表示某个点的时间,它所引导的从句中谓语动词必须用延续性动词。
如果主句表示的是短暂动作,而从句用延续动词的进行时态表示在一段时间内正在进行的动作时,as, when和while都可使用。
如:While I was reading, he came in.他进来时,我正在阅读。
As he walked along the street, he sang happily.他走在大街上,高兴地唱着歌。
④till(until)表示“一直到……(为止)”时,主句和从句都用肯定式,主句的谓语动词必须是延续性动词;not...until表示“直到……才……”时,主句用否定式,从句用肯定式,主句要用短暂性动词。
如:He did not get up till his mother came in.直到他妈妈进来,他才起床。
如何理解并正确运用时间和让步状语从句
如何理解并正确运用时间和让步状语从句时间状语从句和让步状语从句在英语语法中扮演着重要的角色。
正确地理解和运用这两种从句,不仅可以增强句子的表达力,还可以使语言更加丰富多样。
本文将重点讨论如何理解并正确运用时间和让步状语从句。
一、时间状语从句时间状语从句用于表示一个动作或事件发生的时间,它可以出现在主句之前或之后,也可以与主句构成复合句。
我们可以通过以下几个方面来理解和运用时间状语从句。
1. 理解主句和从句之间的时间关系时间状语从句通常由连词when、while、as、before、after、since、until等引导。
其中,when和while都表示"当......的时候",as表示"一边......一边",before表示"在......之前",after表示"在......之后",since表示"自从......以来",until表示"直到......为止"。
我们可以根据连词的不同,来判断主句和从句之间的时间关系。
例如:- When she arrived, we had already started the meeting. (当她到达时,我们已经开始会议了。
)- I will call you as soon as I finish my work. (我一完成工作就给你打电话。
)2. 注意时态和语态的变化在主句使用一般过去时的情况下,时间状语从句中的动词时态通常要使用过去完成时。
而在主句使用现在时、将来时或虚拟语气的情况下,时间状语从句中的动词时态通常要使用一般现在时。
例如:- He said that he had already finished the report. (他说他已经完成了报告。
)- I will call you back when I get home. (我到家的时候会给你回电话。
如何理解并正确运用时间和结果状语从句和条件状语从句和让步状语从句
如何理解并正确运用时间和结果状语从句和条件状语从句和让步状语从句时间和结果状语从句的正确运用时间和结果状语从句是英语中常用的句子成分,可以帮助我们表达时间关系和结果关系。
理解并正确运用这两种状语从句对于我们提高英语表达能力非常重要。
本文将详细解析时间和结果状语从句的概念、用法以及注意事项。
一、时间状语从句的概念和用法时间状语从句用来表示一个动作或事件发生的时间,它通常由副词连词引导,如when(当)、while(当...时候)、before(在...之前)、after(在...之后)等等。
下面是一些常见的时间状语从句的例子:1. When I was young, I used to go fishing with my father.(当我年轻的时候,我经常和父亲一起去钓鱼。
)2. She called me while I was cooking dinner.(她在我做晚饭的时候给我打电话。
)时间状语从句的位置可以放在主句前面或后面,根据语境和需要进行调整。
二、结果状语从句的概念和用法结果状语从句用来表示某个动作或事件发生后的结果,常由副词连词引导,如so(所以)、such...that(如此...以至于)、that(...以至于)等等。
下面是一些常见的结果状语从句的例子:1. He studied hard, so he passed the exam.(他努力学习,所以考试及格了。
)2. It was such a hot day that we decided to go swimming.(天气如此炎热,我们决定去游泳。
)结果状语从句常用来解释原因或给出结果。
与时间状语从句类似,结果状语从句的位置也可以灵活调整。
三、时间和结果状语从句的注意事项1. 语序和时态一致:时间和结果状语从句中的动词时态要和主句中的动词时态保持一致。
例如,如果主句是过去时,从句也要使用过去时态。
2. 连词的选用:根据句子的具体语境和意义,选择合适的连词来引导时间和结果状语从句。
高中英语2025届高考语法复习状语从句知识讲解
高考英语语法复习状语从句知识讲解一、概述常见的有although/though/even though引导的让步状语从句。
if/unless引导的条件状语从句。
until/when/while/as soon as引导的时间状语从句。
because引导的原因状语从句,so that引导的目的状语从句等。
if引导的条件状语从句和when引导的时间状语从句一般都会和时态相结合,即主要考查“主将从现”原则。
对于状语从句的学习可与专题六从属连词相结合。
在时间状语从句和条件状语从句中,主句和从句的时态一致问题一般有两种情况:(1)“主将从现”:主句用一般将来时,而从句用一般现在时。
常见的使用“主将从现”原则的连词有:表示时间的when, while, after, before, until, till, whenever, as soon as, as long as, once 等;表示条件的if, unless, so long as, in case等。
(2)“主祈从现”:若主句是祈使句,或主句中有情态动词时,那么从句用一般现在时表示将来。
(3)“主情从现”:若主句有情态动词, 那么从句用一般现在时表示将来。
如:You can get good grades if you study hard.如果你努力学习,你将取得好成绩。
状语从句由从属连词引导,与主句连接,位于句首时,常用逗号与主句分开,位于句末时,其前一般不用逗号。
状语从句根据其用途可分为时间状语从句、条件状语从句、原因状语从句、目的状语从句、结果状语从句、让步状语从句、比较状语从句、地点状语从句等。
二、时间状语从句(1)当主句是一般将来时态或祈使句,表示将来的意义时,从句通常用一般现在时,简称“主将从现”。
I’ll ring you up as soon as I get to Beijing.我一到北京就给你打电话。
(2) when引导的时间状语从句,通常表示主句和从句的动作同时发生;before表示主句的动作发生在从句的动作之前;after则表示主句的动作发生在从句的动作之后;as引导时间状语从句时,往往表示主句和从句的动作同时发生,不分先后。

时间状语从句和让步状语从句
时间状语从句和让步状语从句一、时间状语从句1.(1)when引导的从句的谓语动词可以是延续性的动词,又可以是短暂性动词。
when有时表示“就在那时”,常构成be about to...when...结构,We were about to leave when she called.When we lived in town we often went to the theatre.(2)as引导的动作是延续性的动作,可以表示主句和从句动作同时发生,意为“一边……,一边……”;as也可以强调“一先一后”。
As we were going out,it began to rain.She always sings as she dances.(3 as soon as表示“一……就……”,类似的结构还有:the minute,the moment,the time,the instant,immediately,hardly...when,no sooner...than等。
Hardly/No sooner had they left when/than it began to rain.Tell him the truth as soon as he arrives.2.通常since引导从句的动词是终止性动词,其主句用现在完成时或现在完成时。
It has been three months since she wrote to me.=It is three months since she wrote to me.二、让步状语从句1.让步状语从句常由下列连词引导:though,although,as,while,even if,even though。
Though it’s hard work,I enjoy it.While I did well in class,I was a poor performer at games.2.whatever,whenever,wherever,whoever,whichever,however在引导让步状语从句时,相当于no matter what (when,where,who,which,how),表示无论在什么条件下进行随意的选择。

如go shopping/come running/stand watching the basketball match。
2、表示心理状态、感觉或情感的动词的特点:⑴如表示被修饰的中心词“令人”怎么样,则用现在分词;表示“感到” 怎么样,用过去分词。
这里有个“土药方”:建议不要把“令人”(-ing)和“感到”(-ed)放在一起理解。
能理解为“感到”时,不放“令人”,反之亦然。
例如:a frightened man(= a man who is frightened)(感到害怕,如理解为“令人感到害怕”也对,也符合汉语习惯,但却易与现在分词的含义相混)、a frightening man(= a man who frightens others)(令人害怕)。
⑵如被修饰的中心词look, voice等,则区别:his surprised look(= the look that shows he is surprised)/his surprising look(= his look that surprises us)。
[拓展]一般说来,分词不可以用very/quite等修饰,但这类分词却不同。
它们已被视为“普通形容词”,既可以用very/quite等修饰,又可以在词尾加上-ly用作副词。
例如:Interestingly enough, the astonished crowd were still quite interested to learn more about the surprising disappearance of Jack, who had just been talking very excitedly about the frightened voice of the "couple" when practising their parts in a play.3、可用现在分词作宾/主语补足语的动词一般有两类:“感觉动词”(如表示听觉的listen to 和hear,表示视觉的look at、see、watch、observe、notice、catch、find,表示总体感第 5 页觉的feel等)和“使役动词”(如have、leave、get、send、set等)。
如何理解并正确运用时间和结果状语从句和让步状语从句
如何理解并正确运用时间和结果状语从句和让步状语从句时间和结果状语从句以及让步状语从句在英语中是非常常见的一种句子结构。
