31题这个句式不是要be动词要用were，或should加动原，但为什么选a阿

Question

如题所述

Answer 1

It's time 后面接虚拟语气
从句谓语通常用过去式表示现在或将来，有时也用过去进行时或“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。
