After a whole day of hard work I'm very tired.It's time we _____ _英语解答

After a whole day of hard work I'm very tired.It's time we _____ home.
A) go B) shall C) went D) should go
为什么答案会是“C”,我感觉“D”才是正确的.went是过去式,但是这个句子不该用过去式啊,更像是表达一种虚拟语气,请英语达人详细讲讲.

解答

C.这是一种习惯用法,是虚拟语气的一种.It's time to go home ,或者 it's time we went home.
