III.阅读理解
A
Soon
enough,
we
will
lose
some
of
the
most
amazing
sites
on
Earth!
The
Great
Barrier
Reef(大堡礁)
Rising
air
temperatures
will
cause
sea
temperatures
to
rise
as
well.
All
life
supported
by
the
oceans
will
be
affected.
Corals(珊瑚虫)
are
some
of
the
animals
easily
affected
and
we
are
already
watching
whole
reefs
disappear.
The
Great
Barrier
Reef
in
Australia
is
no
exception
and
will
continue
to
become
smaller
as
the
temperatures
rise!These
reefs
are
some
of
the
best
in
the
world
for
diving,
but
they
will
soon
disappear!
Venice
Sprawling
across(横跨)hundreds
of
small
islands
in
Northeast
Italy,
Venice
is
at
risk
of
sinking
into
the
Adriatic
Sea.
Rising
sea
levels
are
in
fact
a
serious
threat
to
many
coastal
cities
located
at
sea
level.
Lucky
for
us,
however,
Venice
is
developing
a
series
of
sea
walls
to
protect
the
city
in
times
of
high
tide.
Glacier(冰川)National
Park
Glacier
National
Park
was
once
covered
by
over
150
glaciers,
but
by
2005
it
only
had
about
27!Located
in
Montana,
Canada,
this
park
is
over
a
million
acres(英亩)
and
has
a
huge
plant
and
wildlife
population.
As
temperatures
rise,
the
glaciers
and
ice
melt,
which
will
affect
the
ecosystems
supporting
over
a
thousand
plant
species
and
hundreds
of
animals.
The
Amazon
The
cause
behind
the
disappearance
of
these
fantastic
places
eventually
comes
down
to
humans.
Our
expansion
usually
requires
cutting
down
forests
for
land,
fuel
and
materials,
but
rarely
considers
the
results.
These
forests
are
sources
of
food
and
medicine
for
just
about
everyone
on
the
planet!
What
will
happen
if
we
lose
these
places
and
beautiful
destinations?!
21.
According
to
the
text,
what
is
causing
corals’
death?
A.
Rising
sea
levels.
B.
Rising
sea
temperatures.
C.
Humans’
diving
activities.
D.
The
water
pollution.
22.
What
can
we
infer
from
the
part
of
“Venice”?
A.
Many
places
are
in
the
risk
of
sinking
below
the
sea
level.
B.
Venice
is
the
only
coastal
city
of
Italy.
C.
Venice
will
never
sink
because
of
the
protection
of
sea
walls.
D.
Italy
consists
of
hundreds
of
small
islands
in
the
Adriatic
Sea.
23.
What
can
we
learn
about
Glacier
National
Park
from
the
text?
A.
It
doesn’t
support
any
living
thing
for
its
cold.
B.
It
is
covered
by
over
150
glaciers.
C.
Plant
species
and
animals
in
it
have
died
out.
D.
It
covers
a
large
area
in
Montana.
B
　　Can
small,
organic
agriculture
really
feed
the
world?
Won’t
we
need
science
to
produce
enough
food
as
the
world
population
is
growing
to
9
billion
by
2050?
The
answer
to
both
questions
is
YES—but
that
science
may
look
different
than
you
think.
　　We
have
been
told
that
the
only
way
we
will
be
able
to
feed
the
growing
population
is
through
the
science
of
GM(转基因)
crops
and
chemicals.
But
the
latest
scientific
studies
are
saying
just
the
opposite.
In
study
after
study,
the
message
about
agriculture
is:
To
feed
the
world,
we
need
to
support
sustainable(可持续的)
agriculture
on
different,
local,
family
farms
that
work
with
nature.
　　In
2008,
an
international
study
found
that
sustainable
agriculture,
not
GM
crops,
shows
more
hope
of
ending
hunger.
The
International
Assessment
of
Agricultural
Knowledge,
Science,
and
Technology
for
Development
(known
as
the
IAASTD),
calls
for
a
change
of
the
world’s
food
and
farming
systems.
　　The
Assessment
said
that
industrial
agriculture
has
greatly
destroyed
the
world’s
soils
and
other
natural
resources,
and
now
is
doing
harm
to
water,
energy,
and
weather
safety.
The
report
warns
that
expensive,
short-term
ways—including
GM
crops—are
not
likely
to
cut
down
long-term
hunger,
and
could
even
make
environmental
and
social
problems
worse
in
many
places.
　　A
recent
report
by
the
UN
Environment
Program
shows
that
food
problems
will
become
more
serious
because
of
environmental
problems
and
strongly
supports
sustainable
agriculture
on
small
family
farms.
It
also
showed
that
a
worldwide
change
to
organics
could
actually
increase
the
world’s
food
production
by
as
much
as
50%—enough
to
feed
a
population
of
9
billion
people
with
the
land
we
have
now.
GM
crops,
once
popular,
are
now
being
questioned
worldwide.
24.
How
can
we
feed
the
growing
population
of
the
world
according
to
the
passage?
A.
In
expensive,
short-term
ways.
B.
By
encouraging
industrial
agriculture.
C.
By
developing
small,
organic
agriculture.
D.
Through
the
science
of
GM
crops
and
chemicals.
25.
What
can
we
learn
from
the
passage
if
the
world
supports
sustainable
agriculture?
A.
There
will
be
no
food
problems.
B.
We
increase
a
lot
of
farm
land.
C.
The
environmental
problems
are
solved.
D.
All
the
small
family
farms
are
used.
26.
Which
of
the
following
best
describes
sustainable
agriculture?
A.
The
science
of
GM
crops.
B.
Working
on
small
family
farms.
C.
A
fast
way
to
increase
the
world’s
food
production.
D.
An
approach
to
agriculture
without
harming
the
environment.
27.
What
might
be
talked
about
if
there
is
one
more
paragraph?
A.
The
causes
of
food
problems.
B.
The
disadvantages
of
GM
crops.
C.
The
development
of
industrial
agriculture.
D.
The
disadvantages
of
sustainable
agriculture.

　　Big
changes
in
agriculture
are
taking
place
in
Singapore.
The
small,
Southeast
Asian
nation
is
leading
a
farming
revolution,
according
to
the
Reuters
news
agency.
　　Singapore
covers
724
square
kilometers
of
land
and
only
one
percent
of
that
land
is
used
for
agriculture.
Food
production
costs
are
higher
there
than
the
rest
of
Southeast
Asia.
As
climate
change
and
population
growth
threaten
food
supplies,
the
pressure
is
on
new
farmers
to
answer
the
government’s
call
to
“grow
more
with
less”.
　　“Whenever
I
talk
about
food
security
in
Singapore,
I
tell
people
don’t
think
land
—think
space,
because
you
can
go
upwards
and
sideways.
”
said
Paul
Teng,
an
agriculture
professor
at
Nanyang
Technological
University.
　　There
are
more
than
30
vertical
(垂直的)farms
in
Singapore
—
ones
that
grow
up,
not
across,
the
land.
Sustenir
Agriculture
is
one
of
these
businesses.
Its
hydroponic
(水栽法的)
farm
grows
non-native
foods
like
cherry
tomatoes
and
strawberries
inside
buildings
under
artificial
lighting.
Then
it
sells
the
produce
to
local
supermarkets
and
online
stores.
Sustenir
raised
$16
million
from
investors
(投资人)last
year.
The
money
will
be
used
to
expand
operations
in
Singapore.
　　However,
not
everyone
thinks
the
new
technology
is
the
best.
Egg
farmer
William
Ho
says
the
government
should
not
depend
so
much
on
agriculture
technology
businesses.
“
Many
of
them
have
failed.
That’s
why
I’m
always
asking
the
government
why
don’t
you
invest
in
us
old-timers.
We
are
more
practical,
”
he
said.
Professor
Paul
Teng
said
an
issue
for
urban
farmers
is
that
the
high
cost
of
the
technology
makes
their
products
too
pricey
for
many
people
.
28.
What
does
the
second
paragraph
mainly
discuss?
A.
High
food
production
costs.
B.
Reasons
for
changes
in
agriculture.
C.
Agricultural
technology
businesses.
D.
Sale
expansion
of
food
markets.
29.
What
is
the
way
to
achieve
food
security
according
to
Paul
Teng?
A.
Exploring
up
the
land.
B.
Buying
more
food.
C.
Enlarging
farmland.
D.
Investing
more
money.
30.
What
do
we
know
about
the
old-timers?
A.
They
work
on
high-tech
farms.
B.
They
benefit
from
pricey
products.
C.
They
reduce
production
costs.
D.
They
need
government
support.

Where

　　Organic
food
(有机食品)
is
very
popular.
It
is
also
expensive.
Some
organic
food
costs
twice
as
much
as
non-organic
food.
Some
parents
and
pet
owners
pay
up
to
200
percent
more
for
organic
food
while
some
people
think
organic
food
is
a
waste
of
money.
　　There
is
one
main
difference
between
organic
and
non-organic
food.
Organic
farms
do
not
use
agricultural
chemicals,
such
as
pesticides
(杀虫剂).
This
makes
sure
that
the
products
are
natural.
　　Some
people
think
“organic”
means
“locally
grown”.
At
the
beginning,
this
was
true.
Over
time
organic
farming
became
more
difficult.
The
demand
for
organic
food
grew
larger
than
the
supply.
Small
companies
had
to
sell
out
to
large
companies.
There
weren’t
enough
organic
materials.
This
made
it
difficult
for
many
organic
companies
to
stay
in
business.
Today,
many
large
companies
have
an
organic
line
of
products.
　　Is
organic
food
more
nutritious
(有营养的)?
This
is
part
of
the
debate.
Many
farmers
and
consumers
(消费者)
believe
it
is.
They
think
agricultural
chemicals
cause
health
problems,
such
as
cancer.
Many
health
experts
disagree.
Few
studies
prove
that
organic
food
prevents
health
problems.
Health
experts
worry
more
about
bacteria
(细菌).
These
can
come
into
contact
with
organic
and
non-organic
food.
Doctors
recommend
washing
produce
very
carefully.
　　Most
people
agree
that
naturally
grown
food
tastes
better.
Is
tastier
food
worth
the
extra
money?
This
is
a
matter
of
opinion.
Whether
it
is
healthier
or
not
may
require
more
research.
However,
organic
consumers
argue
it
is
better
to
be
safe
than
sorry.
32.
What
is
probably
the
major
concern
of
organic
food
consumers?
A.
Price.
B.
Safety.
C.
Freshness.
D.
Variety.
33.
What
is
the
doctors’
suggestion?
A.
Grow
your
own
food.
B.
Reduce
the
use
of
pesticides.
C.
Make
sure
the
food
is
clean.
D.
Buy
large
companies’
products.
34.
Which
of
the
following
do
most
people
agree
on
organic
food?
A.
It
tastes
better.
B.
It
is
easier
to
grow.
C.
It
contains
more
fat.
D.
It
is
more
nutritious.

　　You
don’t
have
to
break
your
back
to
create
a
yard
that’s
both
beautiful
and
kind
to
Mother
Nature.
These

　　Let
the
grass
grow.
Cut
grass
less
often,
so
it
gets
a
few
inches
longer
than
you’re
used
to.
　37　
That’s
because
roots
will
grow
deeper
and
grass
thicker,
which
means
fewer
pests,
less
disease,
and
a
decreased
need
for
chemical
intervention.
?
　　Water
the
grass
in
the
right
way.
Water
before
10
a.
m.
,
when
the
air
is
cool
and
not
as
much
moisture
will
be
lost
to
evaporation.
　38　
Water
near
the
base
of

stuff
right
to
the
roots.
For
lawns,
water

　　Get
keen
on
composting(制堆肥).
Compost
isn’t
called
gardener’s
gold
for
nothing.
It
keeps
kitchen
leftover
out
of
landfills
and
enriches
soil
with
much-needed
nutrients.

Honeybees

75
percent
of
our

nearly
75
percent
of
our
food
crops.
There
is
increasing
evidence
that
many
of
the
vital
pollinators
are
in
decline.
Creating
a
garden
that
includes
plants
that
flower
at
different
times
of
the

will
benefit
pollinators
throughout
the

D.
Make

can
go
upwards
and
sideways.
”可知,
当Paul
Teng谈论粮食安全的时候,
他告诉人们不要想土地,
要想空间,

所以,
Paul
Teng认为,
实现粮食安全的途径是通过空间探索土地,
故选A。

asking
the
