# so that系列状语从句不再头疼

1. so that 目的是,以便于
2. so as to 目的是,以便于
3. in order that 目的是,以便于
4. in order to 目的是,以便于
5. so…that… 如此…以至于
6. such…that… 如此…以至于

（1）从上述信息可以看出表示目的是,以便于的词组有4个,分别是so that, so as to, in order that, in order to,其中so that和in order that都是后面要用从句,而so as to和in order to后面用的是短语,这是他们的主要区别,下面我们通过例句具体掌握一下:
I shall write down your telephone number so that I may not forget.
I shall write down your telephone number so as to not forget.

They worked harder than usual in order that they could finish the work ahead of time.
They worked harder than usual in order to finish the work ahead of time.teacheray.com

（2）表示如此…以至于…的词组是so…that…和such…that…,这二者主要区别在于so + 形/副+that 从句,而such +名词+ that从句,如果名词是单数就要用such a /an…that,请看以下例句:
It is so interesting a novel that all of us want to read it.

The place is so cold that nothing can grow in winter.

He gave such important reasons that he was excused.

It is such an interesting novel that all of us want to read it.
