初中英语语法：It is time后的从句要用虚拟语气
一、基本用法
从句谓语通常用过去式表示现在或将来，有时也用过去实行时或“should+动词原形”(较少见，且should不能省略)，其意为“(早)
该干某事了”：
It’s time we ordered dinner. 现在该叫菜了。

I think It’s time you went to bed. 我想你该睡觉了。

It’s time we went [were going, should go]. 我们该走了。

It’s time you washed those trousers. 你该洗洗那条裤子了。

I’m getting tired. It’s time we went home. 我累了，我们
该回家了。

I think it’s time they were taught a lesson. 我想现在该
给他们一点教训了。

It’s time someone spoke up for the less privileged in
our society. 应该有人为我们社会中较不幸的人说说话了。

It’s time you looked ahead and made plans for your retirement. 是你为以后想一想并对退休后的生活做出安排的时候了。

二、同义表达
该是孩子们*的时间了。

It’s time the kids were in bed.
=It’s time for the kids to be in bed.
三、两点说明
(1) time前有时有about和high修饰：
It’s high time we left. 我们早该动身了。

It’s high time you bought a new car. 你该买辆新车了。

I think it’s high time that she made up her mind. 我想她该拿定主意了。

It’s high time they began to take you seriously. 现在他们应该开始认真对待你了。

(2) 与其他的虚拟结构不同，该结构不能在该用 was 时而用were：
It’s time I was in bed. 我该*睡了。

(不用were)。
