【目的状语从句】

 1. 引导目的状语从句的词或词组有:so that, in order that等,从句谓语中含有may, might, can, could, will, would等情态动词。
如:UNICEF believes that all children have clean water and food so that they can be healthy.
联合国儿童基金会认为所有的孩子都应该有干净的水和食物,这样他们才会健康。
He must get up early so that he can do some exercise.
他必须早点起床以便能做些锻炼。
 2. 当从句主语与主句主语一致时,可用so as to, in order to。
如:He worked day and night in order that he could succeed.
=He worked day and night in order to succeed.
他日夜工作为的是取得成功。


【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+a/an十可数名词单数+that(such+形容词+可数名词复数/不可数名词+that)
当名词前有many或much修饰时,用so而不用such。
如:She is such a lovely girl that we love her very much.
=She is so lovely a girl that we love her very much.
她如此可爱,以至于我们都非常喜欢她。
We have so much time that we can finish the work very well.
我们有如此多的时间以至于我们能很好地完成这项工作。
Many of our patients are so poor that they can't afford to travel to hospital.
我们的许多病人如此穷,以至于他们都担负不起去医院的费用。
 2. so ... that句型的否定形式可用简单句too ... to ...或not ... enough to代替。
如: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.
他太小了,不能上学。


【让步状语从句】

用从属连词though, although引导。
注意:though/although与but在句中不能同时出现。
如:We had to go on walking though we were very tired.
尽管很累,但我们还得继续走。
Although I don't have much money, I live a happy life.
