we

in

sentences,

Both
sentence
types
convey
a
similar
meaning,
but
they
are
slightly
different.
For
example,
in
an
active
sentence,
the
subject
is
doing
an
action
to
an
object,
while
in
a
passive
sentence,
the
subject
is
having
something
done
to
it,
and
the
doer
of
that
action
is
not
necessarily
mentioned.
Active
sentences
are
used
often,
as
they
are
more
direct.
Passive
sentences
are
often
used
when
the
doer
of
an
action
is
unknown,
not
important,
or

not
