Question

In this sentence: I knew that in more than one place it must be already broken.

Why is this sentence correct if 'I knew' reffers and talks in the past and moreover is certainty?

Are the following sentences correct? : I knew that in more than one place it must have been already broken.

                                                             I knew that in more than one place it had to be already broken.

 

 

Thanks.

 

 

Answer 1

Proper English doesn't use "it be" together.  You could substitute "was" to make sense, like "I knew that in more than one place it was already broken".

The other two sentences are correct, as well as, "It must have been broken already" and "It had to be broken already."
