请问in order to 与 so as to 有什么区别？

in order to可以用在句首或句末，但so as to只能用在句末。 如： He got up very early in order to/so as to catch the first bus. In order to catch the first bus,he got up very early.（此时不能用so as to） 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）]

两个词组在意义上没有多大区别，但用法有诸多不同，两者的意义都为：为了......在句子中通常做目的状语;不过in order to用法较为灵活,它引导的结构在句子前后皆可,肯定或否定没有限制,如:<1>In order to catch the first bus,she got up very early.<2>上句也可She got up very early in order to catch the first bus.<3>In order not to fail in the coming exam,he studies every day.但so as to引导的结构只能放在句子后面，且通常用于否定结构中，如:He arrived here very early so as not to miss the chance to meet his friend. 回答：2005-05-05 12:03提问者对答案的评价：
查资料没有发现so as to通常用于否定结构中的说法，但均用于目的状语从句，in order to 在句子前后皆可,so as to只能用于句尾.

in order to可以用在句首或句末，但so as to只能用在句末。 如： He got up very early in order to/so as to catch the first bus. In order to catch the first bus,he got up very early.（此时不能用so as to）]

1.so as to(1)使得, 以致.为了(2)如此...以致于 另外,so as to 只能放句中． 2．In order to 表示为了，一般可放在句中或句前，（所以4楼的讲错了！） 例如：In order to catch the train, she hurried through her work. ＝She hurried through her work in order to catch the train. ==She hurried through her work so as to catch the train. 除此之外 >>in order that 为了；目的在于… She hurried through her work in order that she can catch the train. >>of the order of 大约，左右；约与…相同，约与…相似 (= in the order of)]
