in order to的用法：
in order to意為“為了……”，表示目的；在用法和意義上相當於so as to結構，但是in order to結構可以用於句首、句中，而so as to多用於句中。其否定式分別為：in order not to和so as not to。
in order to和so as to在句中表示目的時，常可以轉化成in order that或so that引導的目的狀語從句。
如：We should work hard in order to / so as to pass the exam.→We should work hard in order that / so that we can pass the exam.
為了能通過考試，我們應該努力學習。
“in order that”和“in order to”的區別
in order that後面接句子；in order to後面直接接動詞原形。
例句：
1、In order to earn enough money, he worked late into the night.?
為了賺到足夠的錢，他工作到深夜。
2、In order that training should be effective it must be planned systematically.
