The

I

_______________________________________________
(talk)
to
extraterrestrials
that

on
the
planet
Vulcan
since
1970.
They

________________________________
(be)

and
very

In

I
(3)__________________________________
(buy)
my

and
we
(4)
__________________________________________________
(send)
emails
to
each
other
regularly
since
then.
In
the
past
few
years,
they
have
been
telling
me
about
their
planet.
They
say
it
(5)_____________________________________________(get)
hotter
and
hotter
since
1998
because
their
sun
is
dying.
Their
oceans
(6)_____________________________________________________(lose)
water
very
quickly
and
soon
there
will
not
be
enough
left.
They
will
not
be
able
to
survive
on
Vulcan
for
much
longer.
Over
the
years,
I
(7)
_____________________________________________(tell)
them
a
lot
about
our
planet,
Earth,
and
they
(8)_____________________________________________________________(always
listen)
with
interest.
However,
since
their
sun
started
dying,
they
(9)
_____________________________________________________________(ask)
me
about
the
other
planets
near
Earth.
They
say
that
we
are
lucky
to
have
a
sun
that
is
so
young.
When
I
(10)
_____________________________________(tell)
them
about

Earlier
this
year,
they
told
me
that
they
(11)________________________________________________________(building)
a
spacecraft.
They
are
planning
to
move
to
Mars
because
they
(12)__________________________________________(think)
it
is
the
perfect
planet
for
them.
They
(13)________________________________________(find)
a
way
to
channel
the
underground
water
on
Mars
into
oceans
just
like
those
we
have
on
Earth.
They
(14)_______________________________________________(get)
ready
to
leave
for
Mars
when
I
(15)___________________________________________(call)
them
last
week,
so
they
should
be
arriving
there
in
about
two
years.
I
hope
they
will
visit
us
as
our
new
neighbours.
