Ok. So I am having trouble completing this sentence correctly

By this time tomorrow

  1. I will be gone
  2. I will have gone [future perfect ? ]
  3. I would be gone.

I am starting to think that 3 isn't right.

Is 1 or 2 right ? If no when to use the other one?

Also along wih correct answer, can anyone tell me the rule which explains why it is correct?

  • will have gone... The future perfect. Not sure why 'been' is included.

    All three are possible given an appropriate context. gone can act as subject complement/predicate adjective with BE. gone can combine with auxiliary have to form a perfect tense. I would be gone by this time tomorrow if it weren't for the fact that the airport has been shut down on account of the blizzard.

1 Answer 1


The second one 'future perfect' is the right one because you are talking about tomorrow and 'tomorrow' hasn't come yet.

  • Thank you. why not "will be" ? I know it is not future perfect, but it sounds right. Commented Sep 15, 2017 at 10:23
