时间原因条件状语从句
掌门1对1教育高中英语
时间、原因、条件状语从句
一．when, while 和as 引导时间状语从句的区别用法（一）when 的用法when 从句的A事件，相当于另一个事件B发生的时间点。（也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，）所以when 多数情况下用的是一般过去时，则不用正在进行时。（口头练习）
When I got to the airport, the guests had left.
Why do you want a new job when you have got such a good one already?
(二)while 的用法
while 从句的侧重点在于描述动作正在发生的状态，（它的意思是：当while 事件正在发生的时候，另一件事如何如何。）所以，while 从句一般用的是正在进行时。而另一件事的状态根据具体情况而定。（口头练习）
1. While my wife was reading the newspaper, I was watching TV.
2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看，while 表示的是一段时间，是一个过程。
趁热打铁。Strike while the iron is hot.（这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。）
(三)as 的用法
as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。as 从句用的一般不用正在进行时，而只是一般过去时。可以翻译成“边……边……”。（口头练习）
As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，常常翻译成“随着……”之意。
1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。
2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加，大气越来越稀薄。（少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边，边哭边叫喊。）
Exercise ：
1.the day went on, the weather got worse.
2. Just I stopped my car , a man came up to me.
3.the manager comes here for a visit next week, I’ll talk with him about this.
4. —I'm going to the post office.
— you're there, can you get me some stamps?
Key: As When/as When While
二.until 和till 的用法区别 肯定形式表示的意思是“做某事直至某时”，动词必须是延续性的。 否定形式表达的意思是“直至某时才做某事”。动词为延续性或非延续性都可以。
肯定句：I slept until midnight.
Wait till I call you.
否定句：She didn't arrive until 6 o'clock.
Don't get off the bus until it has stopped. 公共汽车停稳后再下车。I didn't manage to do it until you had explained how. 直到你教我后，我才会做。区别： until 可用于句首，而till 通常不用于句首；表示“直到…才”用until
Until you told me, I had heard nothing of what happened. Not until…在句首，主句用倒装。 Man didn ’t know what heat is until the early years of the 19th century.
Not until the early years of the 19th century did man know what heat is. I
didn ’t realize how much time I had wasted until I began to worl.
Not until I began to work did I realize how much time I had wasted.
三.表示“一……就……”的结构1.as soon as, once, directly, immediately, instantly, the moment, the instant, the minute
2. hardly/scarcely…when/before, no sooner…than (主句常用过完)
As soon as I got home, it began to rain.
=I had hardly / scarcely got home when it began to rain.
=I had no sooner got home than it began to rain.
注意：如果hardly, scarcely 或no sooner 置于句首，句子必须用倒装结构。
Hardly / Scarcely had I got home when it began to rain.
总结：1）as, when 引导短暂性动作的动词。
2）当从句的动作发生于主句动作之前，只能用when 引导这个从句
3）从句表示“随时间推移”连词能用as
No sooner had I got home than it began to rain.
3.Instantly, immediately, directly
I got up to open the door immediately the bell rang.
4.The moment, the instant, the minute
We thrilled with joy the very minute we set foot on the soil of our motherland.

高中英语必修二状语从句教案
一地点状语从句 地点状语从句通常由where, wherever 引导。 Where I live there are plenty of trees.我住的地方树很多。 Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。 二. 方式状语从句 方式状语从句通常由as, (just) as…so…, as if, as though引导。 1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：Always do to the others as you would be done by.你希望人家怎样待你，你就要怎样待人。As water is to fish, so air is to man.我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2）as if, as though 两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如： They pletely ignore these facts as if (as though) they never existed. 他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。） He looks as if (as though) he had been hit by lighting. 他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。） It looks as if the weather may pick up very soon. 看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。） 说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如： He stared at me as if seeing me for first time.他目不转睛地看着我，就像第一次看见我似的。He cleared his throat as if to say something.他清了清嗓子，像要说什么似的。 The waves dashed on the rocks as if in anger.波涛冲击着岩石，好像很愤怒。 三. 原因状语从句 比较：because, since, as和for 1）because语势最强，用来说明人所不知的原因，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as或since。 I didn't go, because I was afraid. 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，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。 He is absent today, because / for he is ill. He must be ill, for he is absent today. 四. 目的状语从句 表示目的状语的从句可以由that, so that, in order that, lest, for fear that, in case等词引导，例如：

时间地点原因状语从句
地点状语从句 常用连词：where 特殊连词：wherever (在……的任何地方), anywhere, everywhere 【点拨】地点状语从句与定语从句的区别：where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。 Go back where you came from.(where引导地点状语从句)你从哪儿来回哪儿去。Go back to the village where you came from. (where引导定语从句，修饰village)回到你来的那个村子里去。 时间状语从句 常用连词：when, as, while, as soon as, before, after, since , till, until, whenever (每当，一……就……) 特殊连词：the minute, the moment, the second, every time, the day, the instant, immediately, directly, no sooner ... than, hardly ... when, scarcely ... when 1．由when, while, as引导的时间状语从句when，while，as都有“当……时候”的意思。 1) when引导的从句的谓语动词既可以是延续性动词，又可以是瞬间性动词，并且when有时表示“就在那时”，相当于and at that time。 It was raining when we arrived. (指时间点)当我们到达的时候，天正在下雨。 When we were at school, we went to the library every day. (在一段时间内) 我们在学校上学的时候，每天都去图书馆。 We were about to leave when he came in.我们刚要离开，就在那时他进来了。 2) while引导的从句的谓语动词必须是延续性的，并强调主句和从句的动作同时发生(或者相对应)，此外，while有时还可以表示对比。 I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。(对比) He fell asleep while/when reading.看书的时候，他睡着了。 Strike while the iron is hot. (用as或when不可以，这里的while意思是“趁……”) 趁热打铁。 3) as表示“一边……一边”，as引导的句子的动词是延续性的动词，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。 We always sing as we walk.我们总是边走边唱。(as表示“一边……一边”) Our headmaster laughed as she spoke.我们的校长边谈边笑。 2．由before“在……之前”和after“在……之后”引导的时间状语从句。 It will be four days before they come back．他们要过四天才能回来。 My father had left for Canada just before the letter arrived. 我父亲恰好在信到之前去加拿大了。 After you think it over, please let me know what you decide. 你仔细考虑过以后，请告诉我你是怎样决定的。

语法讲解 时间状语从句的用法解析及练习
语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语，其位置较灵活，可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号，放在句末时状语从句前面往往不用逗号)。根据状语从句的含义，状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结，希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since，whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析： (1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用延续性动词又可用非延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句：I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如：When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如：Study while you study; play while you play. 该学习的时候就学习，该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时，一边……一边……”，侧重表示两个动作同时发生(包括一个主语同时进行两个动作)，或者一种动作随着另一种动作的变化而变化。例如：He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

时间原因条件状语从句
掌门1对1教育高中英语 时间、原因、条件状语从句 一．when, while 和as 引导时间状语从句的区别用法（一）when 的用法when 从句的A事件，相当于另一个事件B发生的时间点。（也就是说，when 从句的重点不在动作本身发生的状态，而只是把它作为一个时间点，）所以when 多数情况下用的是一般过去时，则不用正在进行时。（口头练习） When I got to the airport, the guests had left. Why do you want a new job when you have got such a good one already? (二)while 的用法 while 从句的侧重点在于描述动作正在发生的状态，（它的意思是：当while 事件正在发生的时候，另一件事如何如何。）所以，while 从句一般用的是正在进行时。而另一件事的状态根据具体情况而定。（口头练习） 1. While my wife was reading the newspaper, I was watching TV. 2. While Jim was mending his bike, Lin T ao came to see him. 从时间的角度来看，while 表示的是一段时间，是一个过程。 趁热打铁。Strike while the iron is hot.（这句话中，是说趁着铁是热的这段时间，赶紧打铁。如果换成when 意思就变了，相当于说铁只热了一下，打一下，然后铁就冷了。这显然不符合文意。） (三)as 的用法 as 从句表示的也是一件事情正在发生，另一件事也正在进行当中。as 从句用的一般不用正在进行时，而只是一般过去时。可以翻译成“边……边……”。（口头练习） As my mother sang those old songs, tears ran down her cheeks. The students took notes as they listened. as 表达的事件，往往只是主句动作发生的背景或条件时，as 只是一个次要的时间说明，常常翻译成“随着……”之意。 1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。 2. The atmosphere gets thinner and thinner as the height increases. 随着高度的增加，大气越来越稀薄。（少数情况下，如果强调动作正在发生，as 从句也可以用正在进行时。The sad mother sat on the roadside, shouting as she was crying. 伤心的妈妈坐在路边，边哭边叫喊。）
初中英语If引导的条件状语从句演示教学
初中英语――if引导的条件状语从句 在if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若if 条件句放句首，从句后面要加逗号，和主句隔开。还要注意前后时态一致原则.引导条件状语从句的连接词主要有：if(如果）、unless（除非）或as long as （只要）等。unless在意思上等于if...not。 一、条件状语从句用法 1、引导条件状语从句最常用的连词是if,由if引导的条件状语从句表示在某种条件下某事很可能发生。如： If you ask him, he will help you. 如果你请他帮忙,他会帮你的。 If you fail in the exam, you will let him down. 如果你考试不及格,你会让他失望的。 另外,if从句还表示不可实现的条件或根本不可能存在的条件,也就是一种虚拟的条件或假设,从句多用一般过去时或过去完成时。如: If I were you, I would invite him to the party. 如果我是你,我会邀请他参加聚会。 2、unless = if...not.除非,若不,除非在……的时候 例如：Let's go out for a walk unless you are too tired. =If you are not too tired, let's go out for a walk. Unless it rains, the game will be played. 除非下雨,比赛将照常进行。 二、时态问题 在条件状语从句中，要注意“主将从现”的规定，即主句用一般将来时，从句用一般现在时表示将来时。例句： I will come to see you if I have time. 我有时间，我就来看你。 三如果if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。如： If bears are in danger ,they attack people. 误区提醒 if 既可以引导条件状语从句，表示“如果”，也可以引导宾语从句，表达“是否”。辨别它在这两种从句中的时态是我们经常容易出错的地方。另外，if 和unless的用法也需注意。 典型例题：----I wonder if your wife to the party. ----If your wife _________, so will mine。. A. will go，go B. will go, goes C.goes, will go D. will go, will go 解析：第一句中if表示“是否”，引导宾语从句，用将来时will go；第二句“如果你的妻子去，我的妻子也去”，if引导条件状语从句，用一般现在时表示将来时。your wife，单三人称主语，所以用goes 。

时间状语从句讲解讲课教案
（adverbial clause of time） 概念：在复合句中，由时间连接词引导的状语从句叫做时间状语从句。(在复合句中，要注意主句和从句的时态大多都要保持一致。） 1.由when, while, as，after,before,since,untill,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。 When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！ 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。 Our headmaster laughed as she spoke.我们的校长边谈边笑。 主要时态：主过从过；主将从现；主句为一般现在时，从句不受影响。 编辑本段when, while和as的区别 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) When I lived in the countryside, I used to carry some water for him. 当我住在农村时，我常常为他担水。（延续性的动词） We were about to leave when he came in.我们就要离开，就在那时他进来了。 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。例如： While my wife was reading the newspaper, I was watching TV. (was reading 是延续性的动词，was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比） 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。例如： We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）As we was going out, it began to snow.当我们出门时，开始下雪了。（as 强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间） 2.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
