.
1. 由when, while, as引导的时间状语从句。
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 bu
rsts 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。
Will you watch my clothes while I have a swim? 我游泳的时
候,请你照看一下我的衣服。
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。

when, while和as的区别
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,我在吃饭。(瞬时动
词)
When I lived in the countryside, I used to carry some wate
r for him.当的住在农村时,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。

2. 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)

3. A s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)

as when while的辨析

as when while都表示主、从句动作同时发生,三者差异如下:
;..


.
as 表示“一边。。。一边”的意思
when 1、还可以表示从句动词的动作在主几句动词的动作”之前 ”或”之后”
发生。
when=and then; at that moment (正在那个时候)
while 1、用于时间较长时
2、 强调两个动作同时进行,并表示对比时
有时这三个连词可以互换,有时不可以。
It was raining hard when (as) I got there.
我到那里时,正在下大雨。 ( 动作同时发生,when可换为as, 但不能换为
while,因为get是点动词.)
When I had read the article, he called me.
我看完这篇文章之后,她给我打了电话。( 从句动作发生在主句之前,注意时
态表达,只能用when )
When I got to the cinema, the film had begun.
(当)我到了电影院时 ,电影已经开演了。(从句的动作发生在主句之后,只能用
when,并要注意时态)
He was about to leave, when the telephone rang.
他正要离开,忽然电话响了。( 此时不能放在句首。主句动词一般表达 “正
在” “即将”.
while, as不能代替
She thought I was talking about her daughter, while, in fac
t, I was talking about my daughter.
他以为我在谈她女儿,然而,实际上在谈论我女儿。(表转折,对比,when, as
都不能代替它)
While the alien was buying a souvenir, the girl called the
police.
外星人 买纪念品时,那女孩给警察打了电话。(表示主句,从句的动作同时发生,
while后引导的状语从句 的动词必须是延续动词不能是点动词,因为它表示较长
时间)
Mother was worried because little Alice was ill, especially
as (when while) father was away.
妈妈担心,因为小爱丽丝病了,特别是他父亲不在家的时候。(此时
as ,when, while可通用)
2.
由till或until引导的时间状语从句。
ti ll和until一般情况下两者可以互换,但是在强调句型中多用until。并
且要注意的是:如果 主句中的谓语动词是瞬时动词时,必须用否定形式;如
果主句中的谓语动词是延续性动词时,用肯定或否 定形式都可以,但表达的
意思不同。例如:
I didn't go to bed until(till) my father came back.直到
我父亲回来我才上床睡觉。
It was not until the meeting was over that he began to
teach me English.直到散会之后他才开始教我英语。
I worked until he came back.我工作到他回来为止。
;..


.
I didn't work until he came back.他回来我这才开始工作。
Please wait until I arrived.在我到达之前请等我。

3.由since引导的时间状语从句。

since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。一
般情 况下,从句谓语动词用一般过去时,而主句的谓语动词用现在完成时。
但在It is +时间+since从句的句型中,主句多用一般现在时。例如:
I have been in Beijing since you left. 自从你离开以来,我一
直在北京了。
Where have you been since I last saw you? 自上次我和你见
面以后,你到哪里去了?
It is four years since my sister lived in Beijing. 我妹
妹不在北京住有四年了。
It is five months since our boss was in Beijing.我们老板
离开北京有五个月了。

知识扩展
1. It is since从。。。以来多长时间了(因为since +从句或名词,表示
一段时间)
It is five years since we met last time.从我们上次见面已经五
年了。
2. It is +before…(。。。才)
It was a long time before I went to sleep again.
过了很长时间我才睡着。
It was an hour before(=until) the police arrived.
过了一个小时,警察才来
soon as, immediately, directly, instantly, the
moment, the instant, the minute, 等引导的时间状语从
句。这些连词都表示“一……就”。例如:
I will go there directly I have finished my breakfast. 吃完
早饭,我立即到那里去。
The moment I heard the news, I hastened to the spot.我一听
到消息,马上赶到了出事地点。
As soon as I reach Canada, I will ring you up. 我一到加拿
大,就给你来电话。

【注意】hardly(scarcely, rarely)…when before, no sooner…than
相当于as soon as之意。主句用过去完成时,从句用一般过去时。当
hardly, scarcely, rarely和no sooner位于句首时,主句应用倒装语序。
例如:
;..


.
He had no sooner arrived home than he was asked to start
on another journey. 他刚到家,就被邀请开始另一旅程。
No sooner had the sun shown itself above the horizon than
he got out of bed to commence work.太阳刚从地平线上升起,他就起
床劳动去了。
Hardly had I sat down when he stepped in.我刚坐下,他就进来
了。
He had hardly fallen asleep when he felt a soft touch on
his shoulder.这个阿拉伯人刚要入睡就感到肩膀上被轻轻一触。
5.由by the time引导的时间状语从句。
注意时态的变化:在一般情况下,如果从句的谓语动词用一般过去时 ,主句的谓
语动词用过去完成时;如果主句的谓语动词用一般现在时,主句的谓语动词用将
来完 成时。例如:
By the time you came back, I had finished this book.到你回
来时,我已经写完这本书了。
By the time you come here tomorrow, I will have finished t
his work. 你明天来这儿的时候,我将已经完成此工作了。

6.由each time, every time和whenever引导的时间状语从句。
例如:Each time he came to Harbin, he would call on me. 他
每次来哈尔滨,总是来看我。
Whenever that man says
“To tell the truth”, I suspect that he's about to tell a
lie.每当那个人说“说实在话”的时候,我猜想他就要说谎了。
You grow younger every time I see you. 每次遇到你,见你更年轻
了。
