状语从句
考点一 状语从句引导词
分类 连接词 例句
时间状语从句 when/while/as, before,after,since, not...until,as soon as She was cooking when someone knocked at the door. I didn’t go to bed until she came back.
条件状语从句 if, as long as, unless They will have a picnic if it doesn’t rain next Sunday.
原因状语从句 because, since, as, for He didn’t catch the first bus because he got up too late.
目的状语从句 so that, in order that Please say it in a loud voice so that everyone can hear it.
结果状语从句 so...that..., such...that... It’s so hot that we want to go swimming. It is such a heavy box that nobody can move it away.
让步状语从句 though/although,even if/ even though,whatever, whenever... Although its raining hard, they are still working hard in the field.
考点二 状语从句-主从句时态
在时间状语从句和条件状语从句中,主句和从句的时态一致问题一般有两种情况:
“主将从现”:主句用一般将来时,而从句用一般现在时。常见的使用“主将从现”原则的连词有:表示时间的when, after, before, until, as soon as,等;表示条件的if, unless, as long as等。
I’ll ring you up as soon as I get to Beijing.
“主祈从现”:若主句是祈使句,从句用一般现在时表示将来。
Be careful when you cross the road.
3. “主情从现”:若主句有情态动词, 从句用一般现在时表示将来。
You can get good grades if you study hard.
温馨提醒:
if引导条件状语从句和宾语从句辨析:if意为“如果”,引导条件状语从句,时态遵循主将从现。If意为“是否”,引导宾语从句。时态视语境而定。
条件状从:I’ll visit the Great Wall if it doesn’t rain tomorrow.
宾语从句: He asked me if I had taken his soap.
I don't know he will come. If he comes,I will tell him about the story.
原因状语从句常用because,since,as, for引导。
(1)由why提出的问题用because来回答,语气最强,一般情况位于主句之后。
I did that because she told me to.
(2)如果状语从句所表示的原因是人们已知的事实,就要用since,而不用as或because。since在这里的意思是“既然”。位于句首。
Since you can’t answer the question,you can ask someone else for help.
as引导原因状语从句,位于句首或句末。
We all like her as she is kind.
for表并列,不表示直接原因,是附加理由,逗号隔开,不能放句首,只能放句末。
He didn't be afraid of snakes,for he is brave.
结果状语从句
(1)由so...that,such...that 引导,so...that与such...that的区别:
so +形容词或副词+ that +句子
such + a / an +形容词+可数名词单数+ that +句子
such +形容词+复数名词+ that +句子
such +形容词+不可数名词+ that +句子
so +形容词+ a / an +可数名词单数+ that+句子
当名词前面有many或much修饰时,用so而不用such。
She is such a lovely girl that we love her very much.
=She is so lovely a girl that we love her very much.
We have so much time that we can finish the work very well.
(2)“so... that+句子”句型的否定形式可用“too +adj +to do或not +adj+ enough to do”结构代替。
He is so young that he can’t go to school.
=He is too young to go to school.
=He is not old enough to go to school.
时间状语从句
(1) when引导的时间状语从句,通常表示主句和从句的动作同时发生;
before表示主句的动作发生在从句的动作之前;
after则表示主句的动作发生在从句的动作之后;
as引导时间状语从句时,往往表示主句和从句的动作同时发生,不分先后。
(2)until/till引导的时间状语从句。
①主句的谓语动词是延续性动词时,主句用肯定形式,表示这一动作或状态一直延续到until/till所表示的时间为止。
I’ll wait for you till you come to see me.我会一直等到你来看我。
②主句的谓语动词是非延续性动词时,用否定形式表示主句的动作直到until所表示的时间才发生。构成句式not...until。
I didn’t go to bed until I finished my homework.
(3)since引导的时间状语从句,表示“自从……以来”,主句用一般现在时或现在完成时,从句用一般过去时。
I have worked in this school since I graduated from Beijing University.
It is 10 years since I began to study English.
让步状语从句中although和but不能同时连用,可将but改为yet。
