a
new
sport
today.
This
sport
takes
you
into
a
wonderful
new
world.
It

like
a

to
the
moon.
When
you
are
under
water,
it
is
easy
for
you
to
climb
big
rocks
,
because
you
are
no

heavy.

Here,

water,
everything
is
blue
and
green.
During
the
day,
there
is
much
light.
When
fish
swim
nearby
,
you
can
catch
them
with
your
hands.

When
you
have
tanks
(罐)
of
air
on
your
back,
you
can
stay

dive

water.

things.

clean
ship
without

of
