在休息日是on the day off 还是in the day off 或者是其他,就是说day off前面的这个介词是什么?,急 last Saterday前面不加介词,但为什么一定是on the next day off,on my last day off what else did you do on your last days off.这句话day为什么要加s,最后一个休息日应该单数啊 在day off前是加介词ON 还是介词 IN? day off the on day's work on the day's work这两者有什么区别the driver went off on day'swork 为什么不能说on the day'swork （Shipments dropped-off after the cut-off time will be uplifted on the next working day)里面的dropped-off 出现过 day off 是表示休息日的 哪位大哥大姐 能告诉小弟 有没有 week off?是啥意思 是表示休息周的么?关乎成绩 请务必说正确的………… 在母亲节是on the mother's day还是On mother's Day? “在第一天”是on the first day还是in the first day “在那天”是on the day还是in the day? 有没有on the day这个说法,为什么我们老师说有day用on,说on the day的意思是在白天. DAY OFF THE DEAD怎么样 i got the day off.i have the day off from work.是我请假了,还是放假了? 是in the day time还是on the day time 是on the open day还是in the open day day off ,用In On At? on my next day off 是什么意思?
