时间状语从句
【知识梳理1】when, while, as
1)表示主句的动作正在进行的过程中，从句的动作发生了，这时候when，while，as可以换用，来引导从句。
2)当表示两个短暂性动作同时发生时，用when，as引导从句。
只能用when的几种情况
1)当主句的谓语是was/ were doing sth，从句的动作突然发生时；
2)当主句的谓语是was/ were about to do时；
3)当主句的谓语是was/ were going to do时；
4)当主句的谓语是was/ were on the polnt of doing时。
【知识梳理3】用while的情况
1) while引导的时间从句的谓语必须是延续性动词，而不能是非延续性动词。
2) while可以表示主、从句所言的两种情况相反或相对比，可译为“而”，但此时while引导
的不是时间状语从句。
【知识梳理4】只能用as的情况
1) as表示“随着……”之意时；
2) as表示“一边……一边……”时；
3)当表示主从句两个短暂性动作同时发生时。
【知识梳理5】表示“一……就……”的连词或短语
1) as soon as，当主句是一般将来时，从句必须用一般现在时表示将来。
2)在hardly.when/ scarcely.when/ no sooner.than结构中，当hardly/ scarcely／nosooner放在句首时，主句必
须用倒装语序；主句的时态须用过去完成时，从句须用一般过去时。
3) the moment，the minute，the second，the instance后直接接从句。
4) immediately，instantly后直接接从句。
【知识梳理6】every morning，every evening，every time，every day，every year（每……）后直接接从句。【知识梳理7】“it was+时间点+when从句”
it指时间点，时间前无介词，when从句是状语从句；当主句是一般将来时，when从句用一般现在时。
【知识梳理8】before
1)…before.表示“没有来得及做某事就……”，主句经常用过去完成时，从句用一般过去时。
2)“it was(not)十一段时间+before从句（一般过去时）”主句是肯定句时，意为“过多长时间才……”；主句是否
定句时，意为“没过多久就……”。
3)“it will be(not)十一段时间十before从句（一般现在时）”主句是一般将来时，从句要用一般现在时表示将来。【知识梳理9】until
1)(not)…until…一肯定句中主句的谓语动词必须是延续性动词；否定句中主句的谓语动词经常是非延续性
动词，也可以是延续性动词。
2)It was not until…that…强调从句时需把not放在从句前面。
3) not until在句首时，主句要部分倒装。
4) until＝till，但是在句首时，只能用until。
【知识梳理10】since
1) since从句总是与时态是现在完成时的主句连用，从句用一般过去时。
2)“It is/ has been十一段时间+since从句”意为“从……到现在多久了”。

翻译：
1、我们正在散步突然下起了大雨。（when）
_____________________________________________________________________________.
We were walking when it rained heavily.
2、中国加入世贸组织至今已十年了。(since)
_____________________________________________________________________________.

3.他似乎过了很久才意识到应该充分利用这个机会。（before）
_____________________________________________________________________________.
It seemed a long time before he realized that he should make full use of this opportunity.
原因状语从句
【知识梳理1】由as／because／since 引导的原因状语从句：
（1）As表示不谈自明的原因，语气最弱。As从句可放在主句之前或之后。
As he was not well, I decided to go without him. 由于他身体不好，我决定独自去了。
（2）Because引导的从句表示直接的原因而不是推断的原因，语气很强，从句是全局的强调部分。往往用来回答why开头的特殊疑问句。它引导的从句一般置于句末，也可置于句首。
-Why did you do it?—I did it because I liked it. 你为什么这么做呢？----我做它是因为我喜欢它。
（3）Since(既然…)引导的从句一般置于句首，引导的从句比because弱，表示推断的、自然发展的原因，比较口语化，它引导的从句通常放在主句前，但也可放在主句后，意为：“既然”。常用在书面语中，表示对方已知或稍加分析便知的原因。Now that 和since意义接近，表示既然，鉴于某个事实。
Since everybody knows about it, I don?t want to talk any more. 既然大家都知道这件事了，我就不多说了。
在下面几种情况下只用because:
1. 回答why提出的问题；
2. 用来引导表语从句。
3.用在强调原因状语从句的强调句之中；
4. 当从属连词前有only, just,simply修饰时。
1. Why is he absent?---Because he is ill.
2. Why he didn?t come to your party was because his father was badly ill.
3. It was because he didn?t recognize you ,he did not speak to you.他不跟你说话，是因为他没有认出你。
4. You shouldn?t get angry just because some people speak ill of you.你不应该因为有人说你的坏话就大发脾气。【知识梳理2】由连词for引导的句子语法上不叫原因状语从句，而叫做补充说明原因的并列分句。它不是一个从属连词而是一个并列连词，for引导的分句不能放在表结果的分句前。For前一般是逗号，但若前一句太长时，for前也可用逗号。表示逻辑上的理由，提供一些有助于说明情况的补充说明，或表示一种推理，一般只用for引导。（所以它引导的分句一般不放在句首。）
There must be no one in the house for the door is closed.房子里一定没有人，因为门是锁着的。
【知识梳理3】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。
由considering that , now that引导的原因状语从句。
Considering that he has only been learning English for a year he speaks it very well.
因为他只学了一年英语，他就能说的很流利。
由介词词组by reason that, for the reason that, in the view of (the fact) that, on account of (the fact) that, on the grounds that, because of, owing to, due to, thanks to, in that等引导的原因状语从句。
He left on the grounds that he was ill.
Wine is scarce here by the reason that it is prohibited.
Owing to the rain, the match was cancelled.
In view of the heavy rain, we will put off the outing.
Thanks to my illness, I have the opportunity to improve my character.
其它的表示原因的从属连词：
The reason…is that…
The reason she refused to go was that she had no money.他不去的原因是他没有钱。

2. because,as ,since,for的区别；
Because：引导的原因状语从句一般放于主句之后，because表示直接原因，语气最强，最适合回答why 引导的疑问句。
As：引导的原因状语从句一般放于主句之前表示已知的、显然的理由(通常被翻译成“既然”)，较为正式，语气比because弱。
Since：引导原因状语从句时表示附带说明的“双方已知的原因”，语气比since弱，较为正式，位置较为灵活(常放于主句之前)。
For：引导的是并列句表示原因但并不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，for引导的并列句只能放于主句之后并且必须用逗号将其与主句隔开。

From snow-clogged mountain roads to desert highways, freeways to crowded city streets, Californians face a variety of tough driving conditions. But thanks to savvy driving, they consume proportionately less gasoline the rest of the nation. Here, some tips from the Golden State that will help drivers all over the country to get up to 25% more miles per gallon! By SUSAN NESTOR
FREEW AY FRENZY
●Try to maintain a steady speed—especially on freeways and expressways. Never exceed a steady 55 mph. Varying
speed by as little as 5mph can reduce mileage by 1.5 miles per gallon. Avoid constant lane changes to“get ahead.”
●Buy radial tyres. If you do a lot of expressway driving, they can increase mileage by as much as 10%. Your fuel savings will pay for the higher tyre price.
ON CITY STREETS
● Plan your route. City driving consumes about 50% more fuel than highway driving (100% more in crowed traffic). Always choose a route with synchronized traffic signals to get the best run for your money.
● Avoid unnecessary braking. Anticipate（预期）traffic light changes; it takes a lot of extra gas to get the car up to speed again.
COLD
●In winter, keep the car in a garage. It will start up easier, and start-up time is when you use the most gasoline. No garage? Cover the engine compartment with an old blanket or rug to shield it from cold winds; remove before starting up.
●Remove all ice and snow. Driving in snow consumes more gas anyway; no sense hauling around extra weight.
65. All these above are ______ for drivers.
A. notices
B. tips
C. lessons
D. advertisements
66. Highway driving can use about ______fuel than city driving.
A. 20% more
B. 20% less
C. 50% more
D. 50% less
67. Which of the following is TRUE?
A. In winter, you will have difficulty starting up a car if it is kept in a garage.
B. Drivers should avoid necessary breaking and constant lane changes.
C. A steady 65 mph is the ideal speed to save gasoline.
D. Radial tyres canhelp increase mileage in expressway driving.

(C)
There will eventually come a day when the New York Times ceases to publish stories on newsprint. Exactly when
that day will be is a matter of deba te. “Sometime in the future,” the paper?s publisher said back in 2010.
Nostalgia (怀旧) for ink on paper, there are plenty of reasons to abandon print. The infrastructure (基础设施) required to make a physical newspaper -- printing presses, delivery trucks -- is n?t just expensive; it?s excessive at a time when online-only competitors don?t have the same set of financial restrictions. Readers are migrating away from print anyway. And though print ad sales still overshadow their online and mobile counterparts, revenue (收入) from print is still declining.
Cost may be high and circulation lower, but rushing to eliminate its print edition would be a mistake, says BuzzFeed CEO Jonah Peretti.
Peretti says the Times shouldn?t waste time getting out of the print business, but only if they go about doing it the right way. “Figuring out a way to accelerate that transition would make sense for them,” he said, ……but if you discontinue it, you?re going to have your most loyal customers really upset with you.”
Sometimes that?s worth making a change anyway. Peretti gives the example of Netflix discontinuing its DVD-mailing service to focus on streaming (流媒体). “It was seen as a mistake,” he said. The move turned out to be fore sighted. “If I were in charge at the Times, I wouldn?t pick a year to end print,” Peretti said “I would raise prices and make it into more of a legacy product.”
The most loyal customers would still get the product they favour, the idea goes, and they?d fee l like that they were helping maintain the quality of something they believe in. “So if you?re overpaying for print, you could feel like that you were helping,” Peretti said. “Then increase it at a higher rate each year and essentially try to generate addi tional revenue.” In other words, if you?re going to print product, make it for the people who are already obsessed with it, which may be what the Times is doing already. Getting the print edition seven days a week costs nearly $500 a year -- more than twice as much as a digital-only subscription.
“It?s a really hard thing to do and it?s a tremendous luxury that BuzzFeed doesn?t have a legacy business," Peretti remarked. “But we?re going to have questions like that where we have things we're doing that don't make sense when the market changes and the world changes. In those situations, it's better to be more aggressive than less aggressive.
68. The New York Times is considering ending its print edition partly due to _______.
A. the high cost of operation
B. the pressure from its investors
C. the complaints from its readers
D. the increasing online ad sales
69. Peretti suggests that in face of the present situation the Times should _______.
A. seek new sources of readership
B. end the print edition for good
C. aim for efficient management
D. strategic adjustments
70. Peretti believes that in a changing world _______.
A. legacy businesses are becoming outdated
B. cautiousness helps problem-solving
C. traditional luxuries can stay unaffected
D. aggressiveness better meets challenge
71.Which of the following would be the best title of the text?
A.Shift to Online Newspapers All At Once.
B.Cherish the Newspapers Still in Your Hand.
C. Make Your Print Newspapers a Luxury Good.
D. Keep Your Newspapers Forever m Fashion. 65～67 BDD 68～71ADDC

初中英语时间状语从句讲解及练习
语法 29时间状语从句 一、什么是状语从句 状语就是在一句话中表示该句子的时间、地点、方式、原因、条件等成分。状语从句就是用一个从 句表示状语。状语从句根据它表达的意思不同，可分为时间、地点、原因、目的、结果、条件、方式、比较、让步等九类。 与状语一样，状语从句的位置比较灵活。既可置于主句之前（通常用逗号与主句隔开），也课置于主句之后（不需要用逗号与主句隔开），有时甚至可以置于主句之中。 二、时间状语从句 1. 主句和从句同时发生，这类从句由从属连词when, while, as引导。 He was hungry when he came home. I was crying while everyone was laughing. As I walked out, he walked in. as, when, while, 的区别 ① as强调从句的动作与主句动作同时发生及持续，具有at the same time的意思 他继续往下谈的时候，越来越兴奋。 as还可以表示一边??一边??，强调从句和主句中两个动作交替进行或同步进行。 他们边走边聊。 as还有“ 随着”的含义 随着春天的到来，天气暖和起来。 ② when 强调动作点的特定时间，具有at the time that 的意思 当老师走进来的时候，我们都站起来了。 ③ while 表示较长的期间，具有during the time that 的意思 当我在这的时候，我很安全。 2.主句发生在从句之前，这类从句由从属连词before, until 引导 ,before 意为“ 在---之前” until 在肯定句中意为“直到 --- 为止”，在否定句中意为“直到 --- 才”。从句既可置于主句前，也可置 于主句之后。 回家之前我必须干完所有的活。
初中英语状语从句讲解、练习与答案(教案)
状语从句 状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状 语从句，地点状语从句，条件状语从句，原因状语从句，结果状语从句，比较状语从句，目的状语从句，让 步状语从句。 1. 时间状语从句 ⑴时间状语从句常用when, as, while, before, after, since, till, until, as soon as 等连词来引导。例如： It was raining hard ( rain hard 下大雨) when got to school yesterday. While he was doing his homework, the telepho ne rang. As he walked along (沿着走) the lake, he sang happily. He had lear ned a little Chin ese before he came to China. After he finished middle school, he went to work in a factory. (2) 在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I ' ll ring you up as soon as I get to New York. I will tell him everyth ing whe n he comes back. He won ' t believe it until he sees it with his own eyes. (3) 在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是一直到……时” 谓语动词只能用延续性动词。如果主句用否定式，其含义是直到……才……”,在…??…以前不……”,谓语动词可用瞬间动词。例如： The young man read till the light went out (熄灭) Let ' s wait until the rain ops. We won' t start until Bob comes. Don' get off (从下来) until the bus stops. 【Till是指直到某一特定事件发生的时候，而在那个时刻之后，该事情或状况仍将持续。Until是指直到某一特定事件发生的时候，而讲话的人在自己心里认为，在那个时刻之后，该事情或该状况将中止 (不怎么可能持续)。固定组合里from morning till night，till/until是不能替换的，】 2. 条件状语从句 (1) 条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don' t leave the buildi ng uni ess I tell you to. (2) 在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I ' ll help you with your English if am free tomorrow. He won ' t be late uni ess he is ill. (3) 祈使句+ and (or)+陈述句”在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you ' ll be late. =If you don ' t hurry up, you ' ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句
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：

(完整版)英语状语从句汇总整理版
英语中的九大状语从句 状语从句在主从复合句中修饰主句中的动词、形容词或副词等，按意义可以分为时间、地点、原因、目的、结果、条件、方式、比较、让步等状语从句。 一．时间状语从句。 通常由从属连词when, whenever, as, while, before, after, as soon as, till, until, since, once (一旦), hardly……when…, no sooner…….than…; 等引导。例如： The cyclist started just as the lights changed to green. Whenever we met with difficulties , they cam to help us. He didn’t leave his office until he had finished the day’s work. 应注意的问题 1．在时间状语从句中，通常要用动词的一般现在时态表示一般将来时态，用一般过去时态表示过去将来时态。但when 引导一般疑问句或名词性从句时不受上述语法规则的限制，因此，应该加以区分。例如： When China will enter WTO depends on the bilateral (双边的)joint efforts. Once you understand the rules of the game, you’ll enjoy it. 2.when , while, as 的不同用法。一般说来，当主、从句的动作是同时发生的事，三者可以换用。when 既可以引导一个持续动作，也可以引导一个短暂动作，可用于主句和从句动作同时发生或从句动作先于主句动作；while 引导的动作必须是持续性的，强调主句和从句的动作同时发生，往往侧重主句和从句动作的对比；as 用于引导“在某行为的继续中发生某事”的“继续之行为”，所以多与过去进行时连用，翻译成“一边……一边……”或者表示动作的变化，翻译成“随着……”。 例如： I hope you’ll think of my words as/when/while you drive on the busy roads. When he realized it, the chance had been lost. When he came home, I was cooking dinner. I was fat when I was a child. He took a bath while I was preparing dinner. As I was walking down the street, an American asked me for the directions to the nearest station. He sang songs as he was taking a bath. As he gets older he gets more optimistic.

初中英语状语从句知识点总结
初中英语状语从句知识点总结(一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导,与主句连接起来。若置于句末,则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词wheｎ,aｆtｅｒ，unｔil,as soon as，等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时,其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如:Ｐlease cａll me ｗheｎ yｏu ｇeｔｔｈere．当你到那时,请给我打个电话。 I ｗill write tｏ you ａs ｓｏｏn as I arrｉｖe in Beｉjing.我一到北京就给你写信。 <温馨提示>siｎce引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It hａs beｅn/is+一段时间+ｓｉnｃe+过去时。 如：I hａs ｂeｅｎ/is three yeａrs since ｗe meｔ laｓt ｔｉｍe.自从我们上次见面,已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as ｌｏnｇ as(只要）等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will ｓtａy at home ｉf it raiｎs tomorrｏｗ.如果明天下雨,我就待在家。 You can’t learn Englisｈweｌl unｌess you woｒk ｈard． 除非你努力学习，否则是学不好英语的。 <温馨提示>由ｉf引导的条件状语从句，若从句表达的是与现在事实相反的事实,则常用虚拟语气,即用过去时态表示(如果涉及到ｂe动词，一律都用wｅre)。此时,主句则用过去将来时。

While he was doing his homework, the telephone rang. As he walked along the lake, he sang happily. He had learned a little Chinese before he came to China. After he finished middle school, he went to work in a factory. (2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如： I’ll ring you up as soon as I get to New York. I will tell him everything when he comes back. He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如：The young man read till the light went out. Let’s wait until the rain stops. We won’t start until Bob comes. Don’t get off until the bus stops. 2. 条件状语从句 (1)条件状语从句通常由if, unless引导。例如： What shall we do if it snows tomorrow? Don’t lea ve the building unless I tell you to. (2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如： I’ll help you with your English if am free tomorrow. He won’t be late unless he is ill. (3)“祈使句+ and (or)+ 陈述句”在意思上相当于一个带有条件状语从句的复合句。例如： Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late. Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill. As it is raining, we shall not go the zoo. Since you can’t answer the question, I’ll ask someone else. (2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。
