The ceiling has been being painted???

I know that we use Present Perfect Continuous in passive voice rarely, nevertheless the majority grammar books says that it can be used. When? In what type of senstences?
Can i change "I have been painting the ceiling" into passive?Thank you in advance by the way, do we say " thank you in advance", because now I'm not sure:)

RH: While the structure may be possible, it is impossible [virtually??] for this situation. Just because we can change an active into a passive grammatically, we don't just automatically do it in language.

The junior high textbooks and workbooks in Japan are full of unnatural passive constructions. Knowing how grammar works is a far cry from knowing how language works.

Are there any examples given for when this structure can be used?

Thank you in advance by the way, do we say " thank you in advance", because now I'm not sure:)

RH: Sure you can say that, Guest and it's quite common.

Yes, you can change "I have been painting the ceiling" into the passive - "The ceiling has been being painted by me". But in so doing you would simply be practicing a mindless exercise, because (except in some unusual circumstances, as described by khoff) nobody talks that way!

The particular tense structure you are aiming at is more comfortably used, on the very rare occasions when it is used at all, when the intent is to express a slowly evolving activity.

For example, let's say that at your company, the management has decided to go out of business. Several months into this process you may find yourself saying,

"It seems management fully intends to carry out its plan. People have been being laid off quite regularly during the past several months."

I'd say that Mr Trask is mistaken. A specific search for, "My house has been being" brings up only one hit and that is Mr Trask and this example. That's not a terrific confirmation.

In these situations we tend to use the impersonal 'they'.

They've been painting my house for two weeks now.

He's right in that it has been assembled in a fully grammatical fashion.
