I'm very tired. It's time [that] we _____ home.
C) should go
I think all the answer all Ok. Could you please correct me?
Same here - though I wouldn't be surprised to hear B if the accent was American (as the Save Our Subjunctive movement is much stronger over there ), and I wouldn't be surprised to hear C if the accent was British and old enough to feel that lip service should be paid to some kind of 'subjunctive' there.
Thanks - I was trying to understand why "go" sounded fine to me when you erudite folks would use only "went." SOS indeed.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
