一、in order to 的用法
in order to 的后面固定加原形动词。此外，in order to 可以放句中，也可以出现在句首，两个位置的差别只在于放句首时，后面要加上逗号，来看以下例句的示范：
为了穿得下婚纱，她最近在节食。
--- She has been on a diet in order to fit into her wedding dress.
--- In order to fit into her wedding dress, she’s been on a diet.
为了成为专业舞者，他以前每天跳舞。
--- He used to dance every day in order to become a professional dancer.
--- In order to become a professional dancer, he used to dance every day.
为了拯救地球，我们必须现在就采取行动。
--- We have got to act now in order to save the planet.
--- In order to save the planet, we have got to act now.
如果做某事的目的是为了让别人怎样，就在 in order to 的中间插入 for somebody，变成 in order for somebody to 即可，如：
The parents slowed down in order for their kid to keep up.
那对父母慢了下来，好让孩子赶上。
He works two jobs in order for his wife to be a full-time mother.
他做两份工作，好让他太太当全职妈妈。
二、in order not to 的用法
前面学到了 in order to 是「为了……」，那如果是想表达「为了不要……」、「以免……」呢？很简单，就在 to 的前面加上 not 即可 ?，这边要小心别放错位置，来看例句：
为了面试不要迟到，我早点出门。
I left home early in order not to be late for the job interview. ⭕️
I left home early in order to not be late for the job interview. ❌
为了不要吵醒家人，她小声说话。
She talked quietly in order not to wake up her family. ⭕️
She talked quietly in order to not wake up her family. ❌
为了不要吵到他太太，他之前有时睡在客房。
In order not to disturb his wife, he sometimes slept in the spare room. ⭕️
In order to not disturb his wife, he sometimes slept in the spare room. ❌
三、小彩蛋：in order that 的用法
好啦～来到小彩蛋时间。上面学到的 in order to 例句，其实也能改用 in order that 来表达，先让你观察一下句子的长相有什么不同吗？
She has been on a diet in order that she can fit into her wedding dress.
为了穿得下婚纱，她最近在节食。
The parents slowed down in order that their kid could keep up.
那对父母慢了下来，好让孩子赶上。
He works two jobs in order that his wife can be a full-time mother.
他做两份工作，好让他太太当全职妈妈。
I left home early in order that I would not be late for the job interview.
为了面试不要迟到，我早点出门。
She talked quietly in order that she would not wake up her family.
为了不要吵醒家人，她小声说话。
从上面可看出，改用 in order that 的话，需要留意一下，有几个小地方会跟用 in order to 不同。一个是后面需要改成接子句，因为这边的 that 是连接词。一个是此时它的位置只会放在句中，不会出现在句首。最后，如果是想表达「为了不要……」，否定是放在后面的子句来表示，而不是用 in order not that ❌。乖，怕你忘记，我们来拿出可爱的笔记本，抄下几个例句加重点吧。
