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
。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。状语从句按其意义和作用可
分为时间、原因、
地点、条件、让步、目的、结果、方式、比较等9种。
1.时间状语从句
时间状语从句表示主句动作发生的时间,主要由when,while,as before,
after; till (until);
once, by the time, as
soon as, no sooner ... than和hardly ...
when及名词词组the moment等引导。
1) when“在……的时候”; while
“在……期间”; as “正当……的时候”
when意为“在……的时候”,强调“特定时间”。
When spring
came, he felt like a trip.
When he was eating
his breakfast, he heard the doorbell ring.
说明:连词when在状语从句中还有如下几种含义:
①表示突然发生的事,含义为“(正在……时)忽然”。
I was just
coming along to see you when I ran into Wilson.
I had been working a couple of months when I
had a letter from Jane.
②表示过早发生某事,意为“(还没……)就”。此含义有时可用before代替。
I
hadn’t been reading for half an hour when I heard
steps outside.
我刚读了不到半个小时就听到外面有脚步声。

had been there little more than a week when I set
to work in earnest.

refuses help when (although) she has many friends.

How can I help them to understand when (if)
they won’t listen to me.
④后接虚拟结构,含义为“本可以,应该……”。
He stopped trying
when he might have succeeded next time.
They
were playing when they could have been working.
while意为“在……期间”,从句用持续性动词,表时间的一段,而不是一点。
While he was eating his breakfast, he heard
the doorbell ring.
We must strike while the
iron is hot.
说明:连词while在状语从句中还有如下几种含义:
①意为“然而,但是”,表示前后对照,说明两种情况相反
Tom is very
outgoing, while Jane is shy and quiet.
Some
people waste food while others haven’t enough.
②意为“虽然,尽管”(多放句首),从句和主句主语多为同一人或物。

一时间里两个相继发生或变化的情况,或两个动作一前一后,有时有
“随着……”的含义。
As he was eating his breakfast, he heard the
doorbell ring. (强调同一时间)
As I was going out, it
began to rain.(强调两个动作先后发生)

the good earth, all flowers begin to bloom. (as
有“随着”的含义)
2) before “在……之前”,after
“在……之后”强调事件的先后关系
before表示两件事的先后关系。主句为肯定句,befo
re引导的从句动作后发生;主句为否定句,
before引导的从句动作先发生。
I
started my meal before he arrived. (从句动作后发生)
He didn’t arrive before I returned. (从句动作先发生)
说明:在不同的结构中,连词before在状语从句中有如下几种含义。

will be ten years before we meet again.
要10年后我们才能再见面。

that little town.傍晚时分我们才到达那个小镇。

you regret.不久你就会后悔的。

told me about this affair.

3) tilluntil,since, once,
by the time

①

admitted to the university.

but he corrected the situation before it got
worse.

realized how old she had become.
直到看见母亲,他才意识到母亲已经变老了。

had read your letter that I understood the true
state of affairs.

时)动作的起始点:

discovered.

meeting you ever since Martin told me.

in bad repair since they lived in it.

ill.

him since he has lived in Shanghai.

you understand the rule,you will have no further

left California.

instantly语气最强,presently最弱。

as I finish the work, I’ll go to see you.

exploded.
Directly I had done it , I knew I
had made a mistake.
5) no sooner ...
than 和 hardly ... when,意为“刚……就…… ”
