How
to
Save
Water
Water
is
very
important
in
our
life.
We
drink
it
every
day
and
use
it
to
cook
and
wash
things.
We
cannot
live
without
water.
But
in
our
daily
life,
we
sometimes
forget
to
turn
off
the
tap.
And
we
take
long
shower.
We
even
throw
rubbish
into
the
river.
Do
you
know
how
to
save
water?
There
are
several
ways
to
save
water.
Firstly,
take
shorter
showers
and
don’t
leave
the
tap
running
when
we
don’t
need
to
use
water.
Secondly,
try
to
reuse
water.
It’s
the
most
important
way
for
us
to
save
water.
At
last,
we
should
not
pollute
water
so
that
we
will
have
fresh
water
for
years
and
years.
If
we
do
not
save
water,
the
last
drop
of
water
will
be
a
teardrop.
To
protect
water
is
to
protect
our
life.
