初中英语 时间状语从句与时态专项
英语时间状语从句讲解与练习引导时间状语从句的普通类从属连词有when （当……时），while（在……期间），as（当……，一边……一边……），before （在……之前），after（在……之后），since（从……以来），till/until（直到），whenever（无论何时），as soon as（一……就）等。如：When I went into the classroom, he was reading. 当我走进教室时，他正在看书。He read a newspaper as he went along. 他边走边看报纸。
We must strike while the iron is hot. 我们必须趁热打铁。
I will tell you after they leave. 等他们走后我再告诉你。
I told him to come back whenever he wants to. 我告诉他什么时候想回来就回来。
I waited till/until she was back. 我一直等到她回来。
Once time is gone, you will never get it back. 时间一旦失去就再也得不到了
注意：在时间状语从句中，不能用一般将来时、过去将来时态或将来完成时，而要用相应的一般现在时态、一般过去时或现在完成时来代替。如：
I’ll telephone you as soon as I get there. 我一到达那里就打电话给你。
She said she would phone me as soon as she got there. 她说她一到达那里就给我电话。
Don’t get off the bus until it has stopped. 等车停稳后才下车。
when, while 和as 引导时间状语从句的用法
这三个词的意思很简单，都有“当……时候”的意思。但学生经常会问三个词的区别在哪儿，特别是在做选择题的时候。别说是学生，就我个人而言，做这样的选择题要保证百分之百的正确也是不可能的。现根据大量的实例和个人的思考，做一点小结，供大家参考。
一、when 的用法
如果只从现象来看，when 从句用的最多的是一般过去时，而主句的时态没有限制,根据具体情况而定。
1. When he was a child he was always trying out new ideas.
他小时候就常常试验一些新的设想。
2. When she came into my room, I was just reading a book. 她走进我房间时，我正在看书。
3. Were you writing when the teacher came in? 老师进来的时候，你在写信吗？
4. Sorry, I was out when you called me. 对不起，你打电话来的时候我出去了。
5. He was on the point of leaving when someone knocked at the door.
他正要走，这时有人敲门。
6. I thought of it just when you opened your mouth. 就在你要说话的时候，我也想到了。
7. I had hardly[scarcely] closed my eyes when someone knocked at the door.
我刚一闭上眼，就有人在敲门了。
根据以上的例句，我们可以总结出一点：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。因为如果用正在进行时，它表示的就是一段时间而不是一个时间点了。根据这一点，有的文章补充说：when 从句的动词大多是瞬时动词。这种说法也
可以参照。实际上，when 从句也可以有其它的时态，但几乎也不用进行时，因为它也只是作为一个时间参照点。例如：
1. When I got to the airport, the guests had left. 当我赶到飞机场时，客人们已经离开了。
2. When he had finished his homework, he took a short rest.
1 / 10
当他完成作业后，他休息了一会儿。
3. Why do you want a new job when you have got such a good one already?
你已经找到如此好的工作，为何还想再找新的？
4. You shall borrow the book when I have finished reading it.
在我读完这本书后，你可以借阅。
5. When the manager comes here for a visit next week, I’ll talk with him about this. 下周，经理来这参观时，我会和他谈谈此事。
二、while 的用法
相比于when 来说，while 从句的侧重点就不一样了。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。而另一件事的状态没有硬性的要求，根据具体情况而定。例如：
1. While my wife was reading the newspaper, I was watching TV.
当妻子正在看报纸的时候，我正在看电视。
2. While Jim was mending his bike, Lin Tao came to see him.
正当吉姆修自行车时，林涛来看他。
3. While they were talking, the bell rang. 正在他们谈话的时候，上课铃响了。
4. You can’t do your homework while you’re watching TV.
你不能一边看电视一边做家庭作业。
5. While John was sitting biting his nails, I was working out a plan to get us home. 约翰坐在那里咬指甲时，我正在制定一个回家的计划。
从时间的角度来看，while 表示的是一段时间，是一个过程。这是while 的侧重点。因此，如果含有“一段时间”的含义的时候，就可以用while。
6. Strike while the iron is hot. 趁热打铁。
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。
再例：
—I’m going to the post office.
—While you’re there, can you get me some stamps?
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。但与while 从句不同的是，as 从句用的一般不用正在进行时，而只是一般过去时。as 从句一般可以翻译成“边……边……”。例如：
1. As my mother sang those old songs, tears ran down her cheeks.
当我妈妈唱起那些老歌时，眼泪顺着她的脸颊流了下来。
2. The students took notes as they listened. 学生们边听课边做笔记。
3. As we talked on, he got more and more excited. 我们继续往下谈的时候，他越来越兴奋。
4. The little girls sang as they went. 小姑娘们一边走，一边唱。
5. Just as he caught the ball, there was a tearing sound.
当他抓住球的时候，有一种撕裂的声音。
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，不像while 从句有强调while 动作本身的意思。因此，as 常常翻译成“随着……”之意。
例如：
1. As the time went on，the weather got worse. 随着时间的推移，气候更加糟糕。
2 / 10
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。
3. As years go by，China is getting stronger and richer.
随着时间一年一年过去，中国变得越来越富强了。
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。这只能算是特例了。
1. 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。
2. As we were going out, it began to snow. 正当我们出门时，雪开始下起来。
3. He came in as I was going to bed. 我正要上床睡觉，他进来了。
四、when, while, as 的互换
如果从句动作和主句动作同时发生，并且从句动作为延续性动词时，when，while，as 可以互换使用。这种情况下，它们的细微区别恐怕连英、美人自己也说不清了。
1. When /While /As we were dancing, a stranger came in.
当我们跳舞时，一位陌生人走了进来。[dance 为延续性动词]
2. When /While /As she was making a phone call, I was writing a letter.
当她在打电话时，我正在写信。[make为延续性动词]
3. While/When/ As I was walking down the street, I noticed a police car in front of the bank.
我顺着马路往前走时，发现银行门前停着一辆警车。
五、比较while, when, as
1）as, when 引导短暂性动作的动词。
例如：Just as / Just when / When I stopped my car, a man came up to me.
我刹车后，有一个人向我走来。
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，不可用as 或while。例如：When you have finished your work, you may have a rest.
干完活后，你可以休息一下。
3）从句表示“随时间推移”连词能用as，不用when 或while。
例如：As the day went on, the weather got worse. 日子一天天过去，天气越变越坏。
2）比较until和till
此两个连词意义相同。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。正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。
肯定句：I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
（在肯定句中可用before代替。例如：Let’s get in the wheat before the sun sets.）否定句：She didn’t arrive until 6 o’clock. 她直到6点才到。
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：1）until可用于句首，而till通常不用于句首。
例如：Until you told me, I had heard nothing of what happened.
直到你告诉我以前，出了什么事我一点也不知道。
3 / 10
3）until when 疑问句中，until要放在句首。例如：
---Until when are you staying? 你呆到什么时候？
--- Until next Monday. 呆到下周一。
注意：否定句可用另外两种句式表示。
4）Not until…在句首，主句用倒装。
例如：Not until the early years of the 19th century did man know what heat is. 直到19 世纪初，人类才知道热为何物。
Not until I began to work did I realize how much time I had wasted.
直到工作，才认识到我已蹉跎了许多岁月。
5）It is not until… that….
例如：It was not until I began to work that I realized how much time I had wasted. 6）表示“一……就……”的结构
hardly/scarcely…when/before, no sooner…than 和as soon as都可以表示“一……就……”的
意思。
例如：
I had hardly / scarcely got home when it began to rain. 刚回家，就下起雨来了。
I had no sooner got home than it began to rain.
As soon as I got home, 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。
例如：
Hardly / Scarcely had I got home when it began to rain.
No sooner had I got home than it began to rain.

一、英语中不同时间和方式发生的动作或状态要用谓语动词的不同形式来表示,这种动词形式称作动词时态。动作或状态发生的时间可以有现在、过去、将来和过去将来四种，而发生的方式也有一般、进行、
5 / 10
1、一般现在时态：
a. 表示经常性或习惯性的动作
b. 现在的特征或状态
c. 普遍真理
d. 有些表示状态和感觉的动词。
如：be, love, like, hate, want, hope, need, prefer, wish, know, understand, remember, believe, guess,
belong, seem, look, have, sound, sound, taste，smell, touch, feel等常可用于一般现在时态。e. 表示未来的时间状语从句或条件状语从句用一般现在时态。
f. 一般现在时态还用在布告、天气预报、报纸、电台。（says）掌握一般现在时态，还请记住下列
单词或词语：always, usually, often, sometimes, every day (morning, week), every other day每隔一天every three days, once (twice) a week (month, year), in the morning
g. 表示按计划或时刻要发生的事情
2、一般将来时态：
a. 表示将要发生的动作或情况。
b. 表示打算、准备做的事或即将发生或肯定要发生的事情。掌握一般将来时态的用法，请记住下列
单词和短语。
In three days (an hour, half a year), next week (Monday, month), tomorrow, this afternoon (evening, coming Saturday-)，soon, some day, tonight, 等等。
3、一般过去时：
a. 一般过去时主要表示过去某时发生的动作或情况（惯性的动作）
b. 在谈到已死人的情况时多用过去时态。
c. 有些情况，发生的时间不很清楚，但实际上是过去发生过的，应当用过去时态。
（1）接到你的信很高兴。I was glad to get your letter.
（2）最后的比分怎么样？What was the final score?
（3）你觉得他们的表演怎么样？How did you like their performance?
（4）我没想到你这样忙。I didn’t know you were so busy

（7）你说什么？What did you say??
掌握一般过去时态的用法，请记住下列单词或短语：
last + 时间点；时间段+ ago；yesterday, just now,
the other day (前几天)
4、过去将来时：
表示从过去某时看将要发生的事情。
5、现在进行时：
a. 表示现在或现在这一阶段正在进行的动作。
b. 在不少情况下，表示正在进行的动作的汉语句子，并没有“正在”这样的字，在翻译英语时必须
用进行时态。例：
(1) 工作进行的怎么样？How are you getting on with your work?
6 / 10
(2) 风挺大（下雨了）It’s blowing hard. (raining)
(3) 你等谁？Who(m) are you waiting for?
c. 在一般现在时态中所列的表示状态和感觉的动词，一般不能用于进行时态，因为它们不能表示正
在进行的动作，但是如果词义转变，表示一个正在进行的动作，就能够用于进行时态。
试比较：
d. 去向性动词的现在进行时可以表示将要发生的动作。但这仅限少量动词，如：go, come, leave,
start, arrive, return等
e. 在there和here引起的句子中，常可用一般现在时态代替现在进行时态：Here comes the bus. = The bus is coming.汽车来了。
There goes the bell. = The bell is ringing.铃声响了。

（2）I read a novel last night. 昨晚我看了一本小说。（可能看完了）
7、现在完成时：表示现刻以前发生的动作或情况，可以是：

一般过去时。d. 当有一个表示到现在为止这段时间的状语时，多用现在完成时。
e. 在有already, yet, just, ever, never, since--, for + 一段时间，by now,
in the past (last) few years, so far, 强调“多少”，“多久”等词的情况下用现在完成时f. 在单纯谈一个过去的动作，不涉及其他对象的影响时，通常用一般现在时；如果谈论一件已经发
生的事情，不考虑它是何时发生的，而主要考虑对现在的影响，则多用现在完成时。例：Did you get up very early？你起来的早吗？
Has he got up? 他起来了吗？
注意：have been to 去过某个地方，已返回
have gone to 去某个地方了
have been in 去了某地多久（在某地多久）
8、过去完成时：
a. 表示过去某时前已经发生的动作或情况（也可以说是“过去的过去”）
b. 在很多情况下没有明显的时间状语，时间由上下文表示出来，这是过去完成时表示的动作较另一
动作先发生。
c. 应当记住，过去完成时是一个相对的时态，表示的是过去的过去。只有在和过去某时或动作相比
7 / 10
较时才用到它。
在包含when, as soon as, before, until, now, that等连词的复合句中，如果主要谓语和从句谓语表示的过去动作是在不同时间发生的，那么先发生的动作通常用过去完成时。但如果两个动作紧接着发生，则通常不用过去完成时。特别是在包含before和after的复合句中。

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。

状语从句。主谓一致。几种时态转换
中考英语语法：状语从句时态类型 1、时态说明 1）在时间和条件状语从句中，通常要用一般现在时表示将来意义，不能直接使用将来时态： I won’t go if it rains tomorrow. 要是明天下雨，我就不去。(不能用will rain) 2）有时也可见到if you will 这样的说法，但那不是将来时态，而是表示意愿或委婉的请求(此时的will是情态动词)： If you will wait a moment, I’ll fetch the money. 请等一下，我就去拿钱。 2、常见类型 状语从句即指在主从复合句中用作状语的从句。状语从句根据其用途可分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句、方式状语从句等： He was angry because I was late. 他很生气因为我迟到了。(原因状语从句) He was so angry that he couldn’t speak. 他气得话都说不出来。(结果状语从句) Although he is poor, he’s happy. 虽然穷，但他仍很快乐。(让步状语从句) Put it where you can reach it. 把它放在你可以拿到的地方。(地点状语从句) Speak clearly so that they may understand you. 讲清楚些，以便他们能理解你。(目的状从) 中考英语语法复习：主谓语法一致的原则 谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。 1. 语法一致的原则 （1）以单数名词或代词，动词不定式短语作主语时，谓语动词要用单数;主语为复数时，谓语用复数，例如： He goes to school early every morning. The children are playing outside. To work hard is necessary for a student. （2）由and或both……and连接的并列成分作主语时，谓语动词用复数。例如：Both he and I are right. Mr Black and Mrs Black have a son called Tom. 但并列主语如果指的是同一人，同一事物或同一概念，谓语动词用单数。例如： His teacher and friend is a beautiful girl. The poet and writer has come. （3）由and连接的并列单数主语之前如果分别由each, every修饰时，其谓语动词要用单数形式。例如： In our country every boy and every girl has the right to receive education. Each man and each woman is asked to help. （4）主语是单数时，尽管后面跟有but ,except, besides, with 等介词短语，谓语动词仍用单数。例如： The teacher with his students is going to visit the museum. Nobody but two boys was late for class. Bread and butter is a daily food in the west. （5）一些只有复数形式的名词，如people, police, cattle, clothes等作主语时，谓语动词要用复数。例如： A lot of people are dancing outside.

初中英语八大时态总结
初中英语八大时态总结 一、一般现在时 具体情况（主要用于下面几情况） 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 在这种情景中，句子常带有表示频率的时间状语：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等，以表示句中的动作或状态是习惯性的、经常性的。例如： They raise ducks as a sideline .他们以养鸭为副业。 It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。例如： He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 3) 陈述客观事实、客观真理。 顾名思义，客观的情况是"没有时间概念"的；也"不会在意动作进行的状态"。例如： The sun rises in the east .日出东方。 4) 根据英文语法规定，当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如： I'll tell him the news when he comes back. 他回来时，我将告诉他这个消息。 *【用于一般现在时的副词，除了上面提到的一些表示频率的以外，常见的还有：now, today , nowadays等等】 二、一般过去时 具体情况（主要用于下面几情况） 1.主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。 例：I was very thin in my childhood. 2.一般过去时由谓语动词的过去式表示，也就是说动词词末要加-ed（除不规则动词外）。常和一般过去时连用的过去时间状语有：last night (week ,month , year , century , etc.) , yesterday , the day before yesterday , yesterday morning ( afternoon , evening ) , in 1999 , two hours ago ( one week ago , tree years ago , …)等等。 例：Did you meet yesterday? He left just now. 3.使用一般过去时，在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。"过去"的时间概念有两层意思：一是指"现在某个时间"以前的时间；二是指"说话、写文章的那个时间点"以前的时间 He got his driving license last month. 他上个月拿到了驾照。
