明天放假用英语怎么说?怎么读?

"Tomorrow is a holiday" 用英语说是 "Tomorrow is a holiday"，读音是 "təˈmɔːrəʊ ɪz ə ˈhɒlɪdeɪ"。

"Holiday"这个词来源于中世纪英语 "haliday"，意思是"圣日"。后来演变成了现在的意思，指的是休假或假期。

例句：

"I'm looking forward to the holiday tomorrow." (我期待明天的假期。)
"I'm going to take a day off tomorrow because it's a holiday." (明天是假期，我要请假一天。)
"What are your plans for the holiday tomorrow?" (明天假期你有什么计划？)
