this has been using in medications for many years.
it is being used for many diseases.
These are two sentences . one is in passive. are they grammaticality correct? do they convey same meaning?
Thank you .
I have one more doubt.
you corrected the first sentence as, 'it has been used'
but, in another sentence like," I have been working here for the past three years." it is ing form (WORKING) is used after 'have been".
but, above , we used past tense (USED) after 'has been'
what is the difference in these two sentences? I mean, the grammar part.
I understood from your answer is, if we use the ing form after have been or has been , it is active voice. right? but there should be a subject. yes?
If you have a present perfect progressive passive, it is a strange form:
It has been being used.
Normally, we avoid been being or be being and either use the active or the simple form
People have been using it.
It has been used.
