工厂放假了英语说作 "the factory is on vacation"或 "the factory is closed for vacation"。
其中, "on vacation" 是一个固定短语, 意思是“正在度假”。而"closed" 则是形容词，意思是“关闭的”。
举几个例子：
The factory is on vacation for two weeks.
The factory is closed for vacation until next Monday.
I heard the factory is closed for vacation, is it true?
翻译为：
工厂放假两周。
工厂休假到下周一。
我听说工厂放假了，是真的吗？
