看绝望的主妇学高频短语:It’s about time
It’s about time: When you want to express that you waited a long time. A synonym of this would be, “finally.”(当你想表达你等待了很长时间的时候。这个词的相近词是“最后”。)When you wait for something, the time on a clock is the biggest factor. As in “It’s about time I got a chance to play.”

中文释义:这里的“It’s about time”不是“这是大概时间”的意思。It’s about time真正的意思是:时间差不多了!It’s about time sb. +过去式,这是虚拟语气的一种用法,比如:It’s about time I went home.(我该回家了。)在It’s (high/about) time 之后的定语从句中需用虚拟语气。谓语动词用过去式,例如:It is high time that you went to school.
