虽然so as to与so… as to在形式上差不多, 而且后面都接动词原形, 但它们表示的意思和在句中的作用却不同: 前者表示“为的是; 是为了; 以便”的意思, 与其后的动词原形一起作目的状语, 用来强调目的; 后者表示“那么地……, 以至……”的意思, so后面接形容词或副词, 在句中as to和其后的动词原形一起作结果状语。

so + adj./adv. + as to do sth. 如此……以致于……
还可以从这个简单句变为：so… that结果状语从句的复合句,
Just now they were so happy that they jumped. 可改为: Just now they were so happy as to jump. 刚才他们高兴得跳了起来。
in order to是so as to的同义词组, 两者一般可互换使用。但是, 当特别强调目的, 且把目的状语放在句首时, 只用in order to。例如:
In order to realize our dreams earlier, each of us must study even harder. 为了早日实现我们的理想, 我们每个人都必须更加努力地学习。
