III. Listening In


Task 1:We should have proper respect for nature!


Martha:
Do you think most people in your culture respect nature?


Ed
: I think so. Um... more now than before.



Martha
: What do
you
think
is
the
most
serious environmental problem
in the world
today?



Ed:
Today
... I think damage to the ozone
layer
is a big problem, and another problem
is pollution in big cities and things like that.



Martha:
How do you learn about environmental problems?



Ed
: Um... through school. A
lot of clubs promote environmental
safety, and some
TV
programs, too. They talk about environmental safety and stuff like that.



Martha:
Do
you
think
students should
learn
more
about
the environment at school?

Ed:
I think so. So, as they grow older, they can be more aware of all the problems that
are going on, and also to prevent more problems from occurring.



Martha:

If
you
could
create
a
new
law
to
help
the
environment,
what
would
it
be?

Ed:

A
new
law
for
the environment?
Um...
I'd probably say that when people throw
away their cigarette butts, they have to throw them into the garbage bin, not just throw
them everywhere because
it's just
littering and I
hate
that. So
they should be
fined
if
they throw them on the floor or on the ground.



Martha:
That's
a
good
idea.
What
do
you
personally
do
to
help
protect
the
environment?



Ed:
I'm so
against
littering. I
never
litter. If I see somebody
litter, I
get really
angry
.
So I always throw my trash into the garbage bin.

Task 2: River pollution

If
you
see
dead
fish
floating
on
the
river
or
notice
that
the
water
is
discolored
and
smelly, you know the river
has been polluted, and there are
four
main possible causes
for it. First, fertilizer. If large amounts of fertilizer or farm waste drain into a river, the
concentrations of
nitrate and phosphate
in the
water
increase considerably. Algae
use
these
substances
to
grow
rapidly
,
turning
the
water
green.
This
massive
growth
of
algae
leads
to
pollution.
When
the
algae
die,
they
are
broken
down
by
the
action
of
the
bacteria,
which
quickly
multiply,
using
up
all
the
oxygen
in
the
water
and
therefore
causing
the
death
of
fish.
Second,
industrial
waste.
Factories
sometimes
discharge
chemical
waste
into
rivers.
Examples
of
such
pollutants
include
cyanide,
lead,
copper,
and
mercury
.
These
substances
may
enter
the
water
in
such
high
concentrations
that
fish
and
other
animals
are
killed
immediately.
Sometimes
the
pollutants
enter
the
food
chain
and
accumulate
until
they
reach
toxic
levels,
eventually
killing
fish
and
other
animals.
Third,
oil
pollution.
If
oil
enters
a
slow-moving river, it forms a rainbow-colored film over the entire surface, preventing
oxygen
from
entering
the
water.
Fourth,
warm
water.
Industry
often
uses
water
for
cooling
processes,
sometimes
discharging
large
quantities
of
warm
water
back
into
rivers.
A
higher
temperature
of
the
water
lowers
the
level
of
dissolved
oxygen
and
upsets the balance of life in the water.

Task3: Curbing carbon emissions


Although it is not an easy task, China is striving to fulfill the promise to cut its carbon
dioxide
emissions
per
unit
of
GDP
by
40
to
45
percent
in
the
next
10
years.
Zhang
Guobao, Director of the National
Energy
Administration, said,

great
emphasis
on
seeking
harmonious
development
between
cities
and
the
environment,
and
is
readjusting
the
energy
structure
by
giving
priority
to
the
development of clean and low- carbon energies, including hydroelectric, nuclear, wind,
and solar power.

Government authorities have closed small, coal-fired plants with a
total
capacity
of
60.06
million
kilowatts
in
the
past
four
years.
This
year's
target
of
closing
10
million
kilowatts
of
capacity
will
be
achieved
by
August.

have
promised
to
the
international
community
that
15
percent
of
our
power
will
be
generated
from
non-fossil
sources
by
2020,
Director
Zhang
said.
At
present,
non-fossil
energy
accounts
for
only
7.8
percent.
China
is
making
efforts
to
increase
the
proportion
of
clean
energy
in
its
total
energy
consumption.
Statistics
show
that
China
invested US$$34.6 billion
in clean energy
last year, exceeding
the United States
which
invested
US$$18.6
billion.
Thus,
China
has
become
the
world
leader
in
generating
clean
energy
.
Five
years
earlier,
China's
investment
in
c
lean
energy
was
only
US$$2.5
billion.

However,
China's
carbon
emission
reduction
target
cannot
be
achieved easily. The shift
to a
low-carbon economy
might be
met at a cost to society
.
For
instance,
more than 400,000 people were
laid off as
a result of the
shutdown of
small
coal-fired
power
plants
in
the
past
four
years.
Many
studies
indicate
that
the
effort
to
curb
greenhouse
gas
emissions
may
delay
China's
development,
affect
people's income, and lead to unemployment.
