a) Despite civic functionaries claiming that funds have been released, these projects are haven't taken off yet.


b) Our buses are haven't left yet, you can still get the bus.

1) Are above sentences constructions correct?

I mean can we use two two auxiliary i.e. are and havent in one sentence.

2)If Yes then above sentense is in simple or Passive tense?

  • You are mixing up some terminology— simple and passive are not tenses, and are not mutual variants of any other grammatical concept. Please edit your post to clarify.

You can have two auxiliary verbs in the same sentence:

They could have gone to a quiet dinner, but they went walking on the beach instead.

but "are haven't" is never grammatical. Pick one or the other, but not both:

The buses haven't left yet, there's still time for you to get on.

The buses are not gone, there's still time for you to get on.

    @user4084 As I said, "are haven't" is never grammatical. Pick one or the other, and modify the sentence accordingly.

  • Sorry but you are giving ambiguous answer. In.first sentence You are saying "are haven't is not grammatical and in next sentence you say that u can pick up are or haven't but not both together. It is confusing me.

  • My question is " Are & haven't " and not "Are or haven't".

    @user4084 I don't think my answer is ambiguous, but I can try to make it more clear: Never use "are haven't". It's not grammatical. You can use "are not" or "have not", The projects are not yet successful or The projects have not yet become successful.
