Last
weekends
,
I
went
to
the
park
to
work
as
a
volunteer
.
I
cleaned
the
floor
up
,
watered
the
flowers
,
planted
some
trees
and
so
on
.
That
was
a
great
experience
.
Although
I
felt
quite
tired
,
it
worth
.
I
loved
all
the
attractive
plants
such
as
sunflowers
,
tulips
,
and
roses
.
I
think
,
if
we
all
gather
together
,
do
something
for
the
public
environment
,
there
will
be
less
pollution
and
more
beauty.
