like to know more about the passive.
Most reference books say that the present perfect continuous
tense has no passive form. Yet, at the same time, we have seen these
building has been under construction for four months and
has still not been completed yet.'
'This building has been being constructed for four months
and has still not been completed yet.'
first sentence 'This building has been under construction...' sounds
much more natural and would always be preferred to the second which
sounds very clumsy.
Generally, we avoid using the continuous form of the
passive with the future, present perfect, past
perfect and future perfect, although present continuous
and past continuous are quite common and sound quite
natural in the passive voice.
For the purpose of the chart below I have used the verb to clean,
but there are obviously many other possibilities:
is being cleaned...
was being cleaned
will be cleaned...
has been cleaned...
had been cleaned...
will have been cleaned
these further examples of use and note how we avoid using
the continuous form of the passive in the final four

inspection will have been carried out and the report will have
been written by the time Charles gets back from America. When
he gets on that plane in New York, the inspectors will be holding
a press conference to report their findings (NOT: their
findings will have been being reported)
avoid using the continuous form of the passive in
these examples by switching to the active voice or by using
people to refer to no person in particular.
Note that in informal English we can also use you
or they to refer to people in general and also in this way
avoid using the passive. Compare the following:
going to build another runway at Heathrow Airport.
new runway will be built at Heathrow Airport some time
