Mr

Can
anyone
tell
me
what
you
can
see
in

photo?
Betty:
There’s
a
factory,
and
it’s
causing
a
lot
of
pollution.
Mr
Jackson:
Correct.
So
what
can
we
do
about
it?

Tony:
Well,
there
should
be
some
rules
to
stop
the
pollution.
Mr
Jackson:
What
about

Daming:
It’s
a

centre.
Waste
products
such
as
glass
and
paper
can
be
recycled
there.
Mr
Jackson:
Good.
Why
do
we
need
to
do
that?

To
save
energy,
I
guess.
Mr

Great!

Lingling:
After
our
lesson
on
the
environment,
I’m
worried
about
the
future.
Pollution
is
our
great
enemy,
and
we
have
to
fight
it.
If
the
rivers
are
polluted,
farmers
can’t
use
the
water
for
their
crops.
Tony:
And
in
some
places,
pollution
from
factories
spreads
over
cities
and
villages.
It
makes
people
ill,
and
may
even
kill
them.
Pollution
is
a
danger
to
our
health.
Betty:
And
there
are
so
many
cars
on
the
roads.
They
use
so
much
oil
and
cause
pollution
as
well.
Daming:
But
we’re
only
students.
We
can’t
do
anything
about
factories
and
cars.
Betty:
It’s
no
use
talking
about
things
we
can’t
do.
We’ve
got
to
think
of
things
we
can
do!
Such
as…?
Do
you
think
we
can
make
our
school
a
green
school?
Lingling:
Daming:
It’s
no
use
doing
sth.
做某事没有用处
比如说……,用来表示举例说明
What’s
a
green
school?
At
a
green
school,
every
class
collects
waste
which
can
be
recycled
or
used
again.
Then
the
school
sells
the
waste
and
uses
the
money
to
help
students
in
poor
areas.
Lingling:
Daming:
Nice
idea!
Daming:
Students
at
a
green
school
also
learn
ways
to
save
energy
and
recycle
at
home.
That
means
less
waste.
That’s
a
good
idea.
Though
pollution
is
heavy
now,
I
don’t
think
it’s
hopeless.
If
everyone
starts
to
do
something,
the
world
will
be
saved.

Betty:
Now
