答案是对的.
词组：it's (high) time that sb.did sth.
那与这个句型：it is time that+(should)do+sth 多用于虚拟语气的啊、
It is time ( about time ,high time ) that ...
该句型中that 后的从句应该用虚拟语气,值得注意的是① 常用过去时态表示虚拟．② 有时也用should 动词原形,一般should 不能省,常译为”是（正是）．．．的时侯．．．”
It is time that children should go to bed.
= It is time that children went to bed.
