so that, so…that 和 such…that 用法归纳
在学习so that 和so…that从句时，有相当一部分同学认为：so that 是用来构成目的状语从句的，而so…that则是用来构成结果状语从句的。其实，情况并不是这样。
so that同样可以用来引导结果状语从句，无论是否有副词作状语或形容词作表语，这就要得从意义上和so that从句的结构上来考虑，表目的的so that状语从句中通常情况下都含有一个情态动词。试比较：
He hurried to the station so that he could catch the early bus. 他匆匆忙忙赶到车站，为的是能搭上早班车。（表目的）
= He got to the station hurriedly so that he could catch the early bus.
He hurried to the station so that he caught the early bus. 他匆匆忙忙赶到车站，结果搭上了早班车。（表结果）
= He got to the station hurriedly so that he caught the early bus.
= He got to the station so hurriedly that he caught the early bus.
The boy was so stupid that he couldn’t work out the maths problem. 这个男孩很笨，所以他解不出这道数学题。
注：① 表目的的so that 从句可以用in order that 替换；若主句和从句的主语一致的时候还可以用so as to或in order to将其转换为简单句。如：
I got up early so that I could be in time for the morning exercises.
→ I got up early in order that I could be in time for the morning exercises.
→ I got up early so as to / in order to be in time for the morning exercises.
② 有时为了加强语气，in order that 从句或in order to短语还可以放到句首，但so that 和so as to却不行。如：
In order that I could be in time for the morning exercises, I got up early.
In order to be in time for the morning exercises, I got up early.
③ 当so…that（或so that）结构的主句中有副词作状语或形容词作表语时，必须用so + adv. / adj. + as to才可以将其转换为简单句来表示结果，否则是表示目的。试比较：
I spoke so loud as to be heard by everyone. 我讲得声音很大，结果大家都听清楚了。（表结果）
I spoke loud so as to be heard by everyone. 我很大声地讲，是为了大家能都听清楚。（表目的）
④ 在so + adv. / adj. + that所构成的结果状语从句中，人们常常把so + adv. / adj. 移到句首并将谓语动词倒装来表示强调。例如：
So hard did the boy study that he passed the exam.
So clever is the boy that he can answer the question.
She was so excited (that) she could hardly fall asleep.
She was (so) excited that she could hardly fall asleep.
She was so excited, she could hardly fall asleep.
The boy is so clever that everyone likes him.
The boy is such a fool that he can’t understand it.
Titanic is such a moving film that all of us want to see it.
The teacher gave the children such wonderful picture books that they got wild with joy.
