谢谢
so as to 和in order to的汉语意思应该是一样的“为的是，为了”。它们的英语功能也是一样的，都可以用来引导目的状语。它们的不同之处就在于so as to 不能用于句子的开头，在句子开头只能用in order to.
另外，
1.in order to 一般用in order that加从句来替换；而so as to 一般用so that加从句来替换。in order that 可以在句首，so that和so as to 一样不能在句首。
2.当这两个短语后的不定式动词的逻辑主语和句子的主语一致时，“in order to , so as to +不定式”可以简化为“不定式”
In order to get to school on time,he got up earlier.这个句子可以表达为下列几种方式：In order that he could get to school on time,....
He got up earlier in order to get to school on time.
He got up earlier in order that he could get to school on time.
He got up earlier so as to get to school on time.
He got up earlier so that he could get to school on time.
To get to school on time, he got up earlier. （这种不定式有时可以表示目的以外的状语）so as to
adv.这(那)样...以致
in order to
为了…起见；以便
In order to catch the train, she hurried through her work.
为了赶火车，她匆匆做完了她的工作。
意思就不一样呀！
so as to 与in order to都可以表示目的,但是so as to 不能用在句首
意思就不一样
so as to 只能用在句中，不能用在句首。
in order to 意思是“为了”：
I answered this question in order to earn some points.
我回答这问题是为了那些积分。
so as to 意思是“这样能够”，和 in order to 差不多。
一样的
