it's time did 与it's time for sb to do有什么区别
例句：it's time we made up our minds.
it's time for us to make up our minds
it's time did 与it's time for sb to do有什么区别例句：it's time we made up our minds.it's time for us to make up our minds
1.it's time 后跟从句表示虚拟语气,意思是本该办的事情却没有办,相当于汉语的“早就该做是某事的时候了”,如：
It's time we made up our minds 我们早就该下决心了（言外之意是迄今还没有动静）.
在这种句型中,从句的谓语动词应该用虚拟形式（同if条件句虚拟形式）,具体如下：
* 对现在虚拟,谓语动词用过去形式.
* 对过去虚拟,谓语动词用过去完成形式.
* 对将来虚拟,谓语动词有三种形式：过去形式；should + 动词原形；were to + 原形.
2.it's time for sb to do后跟不定式表示真实语气,相当于汉语的“到了要做某事的时间了”,如：
It's time for us to make up our minds 现在该是某人下决心的时候了（言外之意即现在马上着手解决）.
两句话的意思是一样的
前者中，we made up our minds是对time的一种说明和修饰，属于从句。
而后句中使用的是it's time for sb. to do的句型，是动词不定式的用法。
