Step1.状语从句的定义:在复合句中作状语的从句叫做状语从句。根据意义上的不同,状语从句可分为:时间状语从句、条件状语从句、目的状语从句、让步状语从句、原因状语从句、结果状语从句、比较状语从句、地点状语从句等等。
Step2.状语从句考点分类:(只讲解学到的六种从句,根据情况增加其余三种)
从句类型
从句引导词
例句
条件状语从句
if; unless; as (so ) long as;(只要)
You will fail if you don't study
hard.
(一将,一现)
原因状语从句
Because, as; since; now (that )(既然),for
Why are you late? Because there
is a traffic jam
(有because,无so)
结果状语从句
so (such )… that ….
He is so poor that he can’t buy a
bike for his son.
so后面没有名词,such后有名词)
让步状语从句
though; although; as; however;
no matter ….; 疑问词+ever;
Though he stayed up late, he could
get up early.
(有though; although,无but)
目的状语从句
so that; in order that
(注意区别in order to)
Please speak louder so that we can hear clearly.(句子中往往有情态动词来表示目的)
时间状语从句
时间状语从句when, while, before, after, until, till since,
as soon as,as,
It was snowing when we got to the
airport.
Step3. 易错清单
PS:1.含有when, if引导的时间状语从句的复合句中,若主句是一般将来时,从句应用一般现在时;(主将从现)when引导其他时态的时间状语从句时,从句时态应与主句时态保持一致。
**when可以引导宾从和状从,意思各不同:when--什么时候(宾从),当...时候(状从)
2. when, while和as的区别: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”;as 表示一边...一边.....
3. 由as 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”。
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。
