The verb go is used with two past participles,
gone and
been:
They have
gone
to Paris.
They have
been
to Paris.
In
the first example they
are not here now;
in
the second they went
and then returned.
We
often use the present perfect with
recently, lately and just
to
talk about something done very recently.
