三．语法——时间状语从句
定义:英语中可以用句子表达一件事情或一个行为发生的时间，这个句子就叫时间状语从句。

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。

1.由when引导的时间状语从句
when意为“当…的时候”，when引导的从句的谓语动词可以是延续性的动词，又可以是瞬间动词。

eg：when the teacher came in, the students stopped talking.
he knocked at the door , when my mother was sleeping.
2.由while引导的时间状语从句“与…同时，在…期间”，谓语动词必须是延续性动词。

eg：lucy was cleaning the room while lily was listening to music.
3. 由before/after 引导的时间状语从句，before“在…之前”，after“在…之后” eg：he went to the office before he visited mr. zhong.
i called betty after i finished the homework.
4. 由until引导的时间状语从句，“直到…为止”，not until “直到…才”
eg：he stayed in the room until his mother came back .
we didn’t begin the meeting until the boss came.
5. 由as soon as 引导的时间状语从句，“一…就”
eg：i took out the notebook as soon as the class began.
四．时间状语从句要注意的几个地方
（1）例如：
it was raining hard（下大雨） when got to school yesterday.
while he was doing his homework, the telephone rang. 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： .
let’s wait until the rain stops.
we won’t start until bob comes.
don’t （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，】
五．when, while 和 as 引导时间状语从句的用法区别
这三个词的意思很简单，都有“当??时候”的意思。

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.
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.
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. 2. when he had finished his homework, he took a short rest.3. why do you want a new job when you have got such a good one already?4. you shall
borrow the book when i have finished reading it.
5. when the manager comes here for a visit next week, i’ll talk with him about this.
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：—im going to the post office.
—while youre 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. the atmosphere gets thinner and thinner as the height increas
es. 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。

【篇二：状语从句教学设计】
teaching plan for the adverbial clause 状语从句
一、考点分析
状语从句是高考句法部分考查的重点内容之一，也是学生比较熟识
的一种复合句，近几年高考重点是考查状语从句的时态呼应，尤其
是时间状语从句和条件状语从句，另外引导状语从句的连接词也是
常考点之一。

二、学生分析
状语从句对于学生来说是比较熟识，状语从句的学习是贯穿在整个
初高中的学习阶段，但状语从句的时态呼应部分对于学生来说还是
一个难点，特别在翻译句子时总是忘了时态的呼应。

三．教学目标：the objectives
1. the students will learn about the adverbial clauses by watching a flash.
2. they will know the 9 kinds of the adverbial clause
3. at the end of the class, they can do some multiple choices and translation
4.the students will learn the 9 kinds of adverbials and their conjunctions.
四．教学重点
时间状语从句和条件状语从句的时态呼应
状语从句的连接词
五．教学难点

六.教学策略
归纳法和启发式教学

状语从句（the adverbial clause）
一．什么是状语从句？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。

在复合句中作状语的句子叫做状语从句。

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．状语从句的种类：
1.时间状语从句：常用的连词有：when, as, while, before, after, since, till (until), as
soon as, hardly…when…, no sooner…than…, the moment 等。

时间状语从句一般不用将来时，因此，主句若为将来时，时间状语
从句要
用一般现在时。

i?ll go on with the work when i come back tomorrow.
as soon as i finish the work, i?ll go to see you.
连词 when/ as / while表示“当……的时候”，但是有区别。

1) when 强调?特定时间?。

例如：when spring came, he felt like
a trip.
2) while表示的时间是一段，而不是一点。

while有时还有对比的含义，意为?而?。

a) while i was waiting for the bus, i met with a friend.
b) some people waste food while others haven?t enough.(表示
对比，意为?而?）
3) as多用在口语中，强调?同时?或“一前一后”，有时还有“随着”
的含义。

as modern industry is developing, there is more and more pollution. (随着) as i was going out, it began to rain. （强调两个
动作先后发生）
翻译：strike while the iron is hot.
when in rome, do as the romans do.
as every thread of gold is valuable, so every moment of time.
as a man sows(播种), so he shall reap (收获 ).
2．条件状语从句：常用if, unless(if…not), as/so long as等词引导。

? i can?t finish the work unless you help me.
? we are going to have a barbecue unless it rains.
1) first conditional（真实条件句）
? 将来有可能发生的事件 if the rain stops, the match will begin. ? 建议或命令某人做某事，提出建议或请求。

if she comes, phone me.
2. second conditional（虚拟条件句）
? 想象的，将来不可能发生的事。

if the sun stopped shining, plants would disappear.
? 现在不可能存在的状态。

if i lived closer to school, i wouldn?t have to get up so early.
3. 地点状语从句：一般由where, wherever, anywhere等引导。

in the future, we?ll be able to use modern technology to go anywhere we like. wherever he went he carried a notebook around with him, in which he wrote down his ideas.
4. 原因状语从句：通常由because, since, as, now that等引导。

since his music style is new, he decided his hairstyle had to be new too. 既然他的音乐风格是新的，他决定发型也得新。

now that she understood the key to language, she was very eager to learn more and use it as much as she could.
既然她理解了语言之谜，她非常渴望学习更多的词语并且尽可能多使用它。

5．结果状语从句：常由that, so that, so…that / such…that等引导。

he is such a young boy that he can?t go to school.
the film was so interesting that i want to see it again.
6. 方式状语从句：由as, (just) as… so…, as it, as though, the way, how等引导。

as water is to fish, so air is to man. 人离不开空气，就像鱼儿离不开水。

sometimes he acts as though he doesn?t even love us at all.
7. 让步状语从句：由though, although, as, whether, even if, even though, however whatever, no matter how / what / who等引导。

today, athletes from around the world can take part, no matter what language they speak.
however good an advertisement is, people are unlikely to be persuaded if the product is unsuitable for them. 无论广告做得多么好，如果产品不适合，人们也不可能信服。

8．比较状语从句：由as…as, than, not as / so…as等引导。

there is nothing in the world as important as health.
some children have more difficulties in learning than others.
9. 目的状语从句：由that, so that, in order that, for fear that, in case等引导。

i got up early so that i could catch the first bus.
he works hard in order that he can pass the exam.

本堂课是语法课，对于语法知识，学生一向是似懂非懂，一知半解，在解题的过程中也是想套语法又套不上，基于这种情况，本节课系
统地对状语从句进行讲解，并指出其解题关键，解题方法，并在讲
解完后，配以一定的练习，进行巩固，收到了良好的效果。

但是在讲解的过程中发现：学生之所以语法掌握不好的原因主要是：语法知识本身比较凌乱，学生记忆中的知识也不全面；语法比较枯燥，学生不感兴趣。

基于这些，在以后的语法课上，要更注重学生
的活动，让学生在动中学，活动要设计稍多点，避免单一活动给学
生带来的枯燥。
