"it's time we go" vs. it's time we went

Hi teachers!!

Could you please tell me what the differences between the following sentences:

1, It’s time we go.
2, It’s time we went.
3, It’s time we were going.



I’d say that you have listed them in order of increasing tentativeness or politeness.

Hi soklong,

You asked for differences in the following:

To be honest, I don’t like number 1. I would prefer to say: It’s time for us to go. The other two are similar although 3 has a greater urgency. They are examples of the subjunctive in English. If you like you can have a look at material I’ve written for the site on the subjunctive:
