你该起床了英文是"It's time for you to get up."。这句话来源于日常生活中人们需要提醒别人起床的情况。例句：

It's 7 o'clock, it's time for you to get up. (时间已经7点了，你该起床了。)

You've been sleeping for 8 hours, it's time for you to get up. (你已经睡了8个小时了，该起床了。)

在这里，"It's time" 是一个固定搭配，意思是"是时候"。例如：

It's time for dinner. (该吃晚饭了。)

It's time for us to go home. (该回家了。)
