on/for one’s holidays/vocations有这样的用法
vacation n.一般表示比较长的假期,多指大学的假期、法庭的休庭期.至于寒、暑假,英国人喜欢用：summer/winter holidays,美国人喜欢用：summer/winter vacation,区别不大.例如：
We spent our summer holidays/vacation in the countryside this year.
My Dad is now on holiday/vacation in Beijing.(表示状态)
Every year,we go to the island for holiday/vacation.(表示目的)
(holiday/vacation用单数,前面也不加冠词,但可用on/for one’s holidays)
vacation v 休假； n （地方的）腾出、（职位的）辞去,例如：
Let’s vacation in Hawaii next month.(《英汉多功能词典》 外研社/建宏出版
