二、知识讲解
考点1——时间状语从句
常用引导词:
when,as,while,as,soon
as,while,before,after,since,till,until
特殊引导词:the minute, the moment, the day,
immediately,no sooner ?than, hardly ?
when,
scarcely ? when
1) when, while, as的区别:
①
三者均可表示“当??的时候”, 如果主句表示的是短暂的动作, 而从句表示的是一段
时间,
三者可通用。
② as和when都可与终止性动词连用, while
只能与延续性动词连用。如:
It was snowing ____ we got
to the airport.当我们到达机场时, 天正下着雪。(不
能用 while)
③as强调主句与从句表示的动作同时发生;
while强调主句表示的动作持续于while所指的
整个时间内;
when可指主、从句所述动作同时或先后发生。如:
He sang as he
went along. 他边走边唱.
Please write____ I
read. 我读的时候, 请写下来。
____ he reached
home, he had a little rest. 回到家后, 他休息了一会儿。
Whenever we met with difficulties, they came
to help us.
I got in touch with him
immediately I received his letter.
My sister
came directly she got my message.
Every time I
catch a cold, I have pain in my back.
如果把no
sooner, hardly, scarcely,
barely置于句首,它所连带的这部分要倒装,如:
No sooner had
she heard the news than she fainted.
(She had no sooner heard the news than she
fainted.)
考点2——条件状语从句
常用引导词:
if,unless,(if not)
特殊引导词:asso long as,on
condition that
① We’ll start our project ___
the president agrees.
② You will certainly
succeed ____ ___ ___ you keep on trying.
要点:
引导条件状语从句的连词有if(如果)、unless(除非)等, unless在意义上相当于
i
f?.not。条件状语从句也像时间状语从句一样,如果主句用将来时,
从句要用现在时代
替将来时。如:
You will fail ____ you
study hard.
(=You will fail if you don't study
hard.)除非你努力学习, 否则你会失败。
注意:有时可以把祈使句作为条件从句,祈使句后面要搭配and,如:
Come tomorrow, and I will tell ere and you will
succeed.
Give him an inch and he’ll take
a mile. (= If you give him an inch, he’
ll
take a mile. )
但:当表示否定的条件时,可用连词or 或otherwise, 如:
Make up
your mind, or you’ll miss the chance.
Start at
once, or otherwise you’ll miss the train.
(=
If you don’t start at once, ?)
(= Unless
you start at once, you’ll miss the train.)
考点3——原因状语从句
(1)常用引导词: because, since,
as , now that
(2)because, since, as, for 用法比较:
一).because: 语气最强,回答why引导的疑问句,该从句一般位于主句后,所表示的是直
接理由,因果关系不能同so连用。
Why are you late?
Because there is a traffic jam.
—Why can't I
go? 为什么我不能去?
— ____ you're too young.
因为你年纪太小了。
二).since: “既然?..”
表对方已知的事实或理由,从句常放在句首。since比as正式。
Since you
have got enough money with you now, you can come
and buy it next time.
三). as: “由于?.”
语气较弱较口语化,表明显的原因或已知的事实,从句常放在句首。
As he had
been ready for the worst, he was not disappointed
at the result.
____you are not feeling
well,you'd better stay at home.
既然你不太舒服,还是留在家里的好
四).for是一个等立连词,连接的是两个并列的分句
,其他三个引导的是状语从句;for
不能放在句首。
It must
have rained last night, for the ground is wet.
考点4——目的状语从句
常用引导词:so that,in
order that
引导目的状语从句时,从句中常有can, could, may,
might, would
① The boss asked the secretary to
hurry up with the letters _____ _____ he could
sign them.
② The teacher raised his voice
_____ _____ _____ the students in the back
could
hear more clearly.
考点5——结果状语从句
常用引导词: so?that,such?that
1. so?that和such?
that引导的结果状语从句,意为“如此..以至于”,用来补充说明主
句动作发生所带来的结果
The boy is so young that he cannot go to
school
It is such nice weather
that i would like to go to the beach
?that中so是副词,用来修饰形容词或副词:so + 形容词副词分词 +
that引导结
果状语从句
He studied so hard that he
made great progress
such?that中
such是限定词,只能修饰名词和名词词组,such + (形容词) + 名词 +
that
引导结果状语从句
Mike is such an honest man
that we all believe
3.(1)主+谓+so++that 从句.
(2)主+谓+so+adj+a(n)+单数名词+that从句 .
主+谓+such+a(n)+adj.+单数名词+that从句 .
It’s such
a fine day that we all want to go outing.
= It’s so fine a day that we all want to go
outing.
(3)主+谓+so+manymuchfewlittle(少)+名词+that从句 eg.
if修饰名词的形容词为many,few,much,little时,前面则用so,例如:
比较:so many few flowers → such nice flowers
so much little money → such rapid
progress
so many people → such a lot of
people
(5)主+谓+such+adj.+复数名词+that从句 eg.
(6)主+谓+such+adj.+不可数名词+that从句 eg.

up ___ early that he caught the first
bus.他起得很早,赶上了第一班车

whenever, wherever, whichever, however)

② ____ _____ how hard the
work was,he never gave it up.

to see him.
