to这三个短语有什么区别，并适合用在什

Question

如题所述

Answer 1

1. (not) to, so as (not) to和in order (not) to都可以视为是不定式短语,在句中都做目的状语.
其否定形式都是在to前面加上not.
2. 唯一的区别就在于：to和in order to...可以放在句首/句中/句尾,但是so as to...不能放在句首.
3. 它们三个后面都加动词原形.
如：We should work hard to/so as to/in order to succeed in the future.
但是可以说：To/In order to succeed in the future, we should work hard.
不能说：So as to succeed in the future, we should work hard.
