so that, so…that 和 such…that 用法总结
 
在学习so that 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.
但若副词或形容词是放在so …that之间,就算that从句中含有情态动词也只能表示结果。
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: 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 toin 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.
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 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.
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)
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.
人们在口语中常省去so…thatthat,也有人省去so而保留that。如:
She was so excited (that) she could hardly fall asleep.
She was (so) excited that she could hardly fall asleep.
在书写中省去that时,最好加上逗号,把句子的两个部分隔开。例如:
She was so excited, she could hardly fall asleep.
so…thatsuch…that都可以构成结果从句,所不同的是so…that之间接形容词或副词,而  such…that之间接名词。一般情况下,即使名词前有形容词修饰也不能换用so…that。例如:
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.
