Reading

Look
at
the
pictures
on
the
next
page.
Say
which
ways
are
good
for
the
environment
and
why.
1
It
is
better
to
use
a
lunch
box
and
china
cup
than
a
paper
bowl
and
cup,
because
they
are
reusable,
paper
cups
can
only
be
used
once
and
have
to
be
thrown
away.
It
is
much
better
to
recycle
used
things
than
burn
them.
In
this
way,
we
can
use
less
energy;
also,
burning
pollutes
the
air.
Look

the

It’s
better
to

How
to
be
green
By
Wang
Lingling
How
green
are
you?
Answer
these
questions
and
find
out.
Do
you
walk
or
ride
a
bike
to
school?
Do
you
buy
new
clothes
just
because
they
are
modern?
Do
you
turn
off
the
lights
when
you
leave
the
room?
Do
you
take
your
own
bag
when
shopping
and
not
ask
for
a
plastic
bag?
Do
you
buy
drinks
in
bottles?
And
what
do
you
do
with
the
bottles
when
they
are
empty?
Do
you
divide
the
waste
into
things
to
recycle
and
things
to
throw
away?
扔掉、丢弃
We
all
need
a
healthy
environment,
but
we
produce
waste
every
day,
and
it
is
harmful
to
our
environment.
Repeat
these
three
words
daily:
reduce,
reuse
and
recycle.
Reduce
Reduce
means
“use
less”.
Do
not
waste
things.
It
saves
money
and
causes
less
pollution.
Do
not
order
more
food
than
you
can
finish.
Turn
off
the
lights
when
you
do
not
need
them.
Before
you
buy
something
new,
think
whether
it
is
really
necessary
because
maybe
the
old
one
is
just
as
good
!
Reuse
Reuse
means
“use
again”.
Use
things
for
as
long
as
possible.
Look
after
them
so
that
they
will
last.
Repair
them
if
possible.
Do
not
throw
them
away
and
buy
new
ones.
Do
not
use
paper
cups
or
paper
bags.
It
is
better
to
use
china
cups
and
cloth
bags
because
they
can
be
used
many
times.
Recycle
Recycle
means
“change
things
into
something
else
to
be
reused”.
Although
it
takes
energy
to
change
things
into
something
else,
it
is
better
than
throwing
things
away
or
burning
them.
change…into…
“把…变成…”
We
throw
tons
of
rubbish
away
each
year,
and
we
have
to
make
a
change.
Divide
your
rubbish
into
plastic,
glass,
paper
and
rubber.
Develop
a
recycling
policy
for
the
whole
community.
Buy
products
such
as
recycled
paper
to
help
save
trees.
We
cannot
hope
for
rapid
change,
but
let’s
take
these
simple
steps
today
so
that
we
will

the
world
for

Possible
answer:
Help
make
a
green
school
We
can
do
many
things
to
make
our
school
green.
Remember
the
three
most
important
words:
reduce,
reuse
and
recycle!
Reduce
Many
people
waste
paper
because
paper
is
cheap.
But
we
should
use
less
paper
so
that
we
can
save
trees.
Make
sure
you
write
or
print
on
both
sides
of
the
paper
so
that
nothing
is
wasted.
This
simple
tip
will
cut
your
paper
usage
in
half!
Reuse
Many
people
like
disposable
cutlery（一次性餐具）because
they
don’t
have
to
wash
up.
But
it
isn’t
green.
Bring
your
own
chopsticks
from
home
and
reuse
them.
Don’t
use
disposable
cups
or
plates,
either.
Recycle
We
all
eat
and
drink
at
school
every
day,
so
there
are
plenty
of
wrappers,
bottles
and
cans
to
dispose
of.
But
don’t
just
throw
your
bottles,
wrappers
and
cans
in
the
rubbish
bin
—
support
the
school’s
recycling
programme!
Put
paper,
plastic,
glass
and
metal
in
the
recycling
bins.
Follow
these
steps
and
we’ll
all
have
a
green
school!
