It’s
very
important
that
we
all
recycle.In
nature
everything
is
1
again.For
example，when
an
animal
dies，
it
becomes
2
animal’s
food.Nothing
is
wasted.But
humans
have
created
things
like
plastic
bags
3
can’t
be
broken
down
by
nature.Our
rubbish
kills
animals
and
4
water
and
soil.
5
we
continue
making
too
much
rubbish，the
problem
will
only
get
worse.
巩固提升
Work
seriously
If
nature
can’t
reuse
the
rubbish，
we
must
recycle
6
.We
should
clean
up
the
rubbish
we’ve
made
because
nature
can’t.
Recycling
is
also
the
right
thing
to
do
for
another
reason.The
earth
is
rich
in
natural
materials
like
water
and
trees，
7
these
materials
are
not
endless.
巩固提升
Work
seriously
We
use
up
our
natural
materials
much
8
than
the
earth
is
able
to
reproduce
them.For
example，each
year
we
cut
9
more
than
6，000
square
miles
of
forest，
but
it
takes
an
average
of
25
years
for
a
new
tree
to
10
.
