1.
To
listen
to
a
radio
interview
about
the
use
of
fossil
fuels
and
other
sources
of
energy.
2.
Learn
to
express
agreement
and
disagreement.
We
depend
on
energy
to
do
many
things
in
our
daily
life.
Make
a
list
of
the
things
that
consume
energy.
Where
does
all
this
energy
come
from?
Windmills
a
coal
power
station
Wind
energy
is
used
as
power
to
produce
electricity.
Electricity
is
produced
by
burning
coals.
an
oil
refinery
（炼油厂）
a
nuclear
power
plant
A
facility（设施）
designed
to
convert
nuclear
energy
into
electricity.
Oil
is
refined
and
made
pure.

are
used
to
keep
back
water
and
raise
its
level
for
irrigation
（灌溉）or
for
producing
electricity.
An
energy
source
is
“renewable”
when
supplies
of
it
never
run
out
and
“non-renewable”
when
one
day
they
will
run
out.
Which
energy
sources
on
your
list
are
renewable
and
which
are
non-renewable?
Li
Bin
is
interviewing
Professor
Keeling
about
using
different
sources
of
energy.
Read
the
statements
below
and
tick
the
ones
you
agree
with.
We
should
stop
depending
on
fossil
fuels
for
our
energy.
2.
90%
of
our
energy
comes
from
fossil
fuels.
3.
We
can
replace
fossil
fuels
with
cleaner
sources
of
energy.
4.
Nuclear
power
is
a
good
source
of
energy.
Listen
to
Part
1
and
decide
which
statements
Professor
Keeling
does
NOT
agree
with.
We
should
stop
depending
on
fossil
fuels
for
our
energy.

Listen
to
Part

again
and
tick
the
energy
sources
that
are
mentioned.
Complete

notes
on
them.

Listen
to
Part
2
and
then
list
three
things
we
can
do
to
save
energy.
First,
we
must
try
to
find
ways
to
use
fossil
fuels
that
does
not
put
carbon
dioxide
into
the
air.
Second,
we
must
produce
products
that
are
economical
with
energy.
Third,
we
must
ask
people
to
cut
down
on
the
energy
they
use.
Listen
to
part
2
again
and
fill
in
the
blanks.
LI
BIN:
…
What
about
________?
They
don’t
cut
down
on
their
use
of
______.

KEELING:
No,
they
don’t.
However,
that
is
a

must
work
on

That
means

LI
BIN:
But
it’s

Now
read
again
what
Professor
Keeling
and
Li
Bin
say.
Then
in
groups
discuss
who
you
agree
with
and
give
reasons.
Use
some
of
the
phrases
listed
below
or
any
others

you.
I’m
afraid
not.
No,
I
don’t
agree.
No
way.
I
doubt
….
The
minimum
effort
is
also
a
kind
of
support.
再小的力量也是一种支持。
