on holiday与in holidays与on holidays的区别？

详细一点，举些例子。

on holiday---adv.在度假
in holidays---在假期中
on holidays---度假时

in holiday 泛指放假，但说话人说话的时候并不在放假。 如，i'd like to stay with my families in holiday. in the holiday 指特定的假期，根据上文的延续。 如，christmas is a spcial holiday in western countries. in the holiday, people usually stay with their families. on holiday 处于放假的状态 如，i'm on holiday now.类似有on duty 上班中 帮你造了几句话,你可以通过理解句意来看区别,希望对你有用 on the holiday: a few more traveller's cheques may come in handy on the holiday. 多带几张旅行支票，度假时会有用的。 in the holiday: we (enjoy ourselves) in the holidays. in the holiday season one finds the trains unpleasantly full of people. 节日期间，人们可以看到火车上拥挤不堪，人满为患。 如果你前面曾经提起过某个节日，而现在针对这个节日说on，就要用on the holiday,特指在这个节日。否则，用on holiday.
