Part III Reading Comprehension
（
40
minutes
）
Section A
Directions: In
this section, there is a passage with ten blanks.
You are required
to
select
one
word
for
each
blank
from
a
list
of
choices
given
in
a
word
bank
following the passage.
Contrary to
popular belief, older people generally do not want
to live with their
children.
Moreover,
most
adult
children
_____(26)every
bit
as
much
care
and
support to their aging
parents as was the case in the
older
people do not feel _____(27).
About 80% of
people 65 years and older have living children,
and about 90% of
them have
_____(28)contact with their children. About 75% of
elderly parents who
don't go to nursing
homes live within 30 minutes of at least one of
their children.
However, _____(29)having
contact with children does not guarantee happiness
in old age. In fact, some research has
found that people who are most involved with
their families have the lowest spirits.
This research may be _____(30), however, as ill
health often makes older people more
_____(31)and thereby increases contact with
family members. So it is more likely
that poor health, not just family involvement,
_____(32)spirits.
Increasingly,
researchers
have
begun
to
look
at
the
quality
of
relationships,
rather than at the frequency of
contact, between the elderly and their children.
If
parents and children share interests
and values and agree on childrearing practices
and religious _____(33)they are likely
to enjoy each other's company. Disagreements
on
such
matters
can
_____(34)cause
problems.
If
parents
are
angered
by
their
daughter's divorce, dislike her new
husband, and disapprove of how she is raising
their grandchildren, _____(35)are that
they are not going to enjoy her visits.

statement contains information given in one of the
paragraphs.

which the information is derived. You may choose a
paragraph
more
than
once.
Each
paragraph
is
marked

the
questions by marking the
corresponding letter on Answer Sheet 2.
Could Food Shortages Bring
Down Civilization?
[A]
For
many
years
I
have
studied
global
agricultural,
population,
environmental
and economic trends and their interactions. The
combined effects of
those trends
and
the
political
tensions
they
generate point
to the
breakdown
of
governments and societies. Yet I, too,
have resisted the idea that food shortages
could bring down not only individual
governments but also our global civilization.
[B]
I
can
no
longer
ignore
that
risk.
Our
continuing
failure
to
deal
with
the
environmental declines
that are undermining the world food economy forces
me to
conclude that such a collapse is
possible.
[C]
As
demand
for
food
rises
faster
than
supplies
are
growing,
the
resulting
food-price
inflation
puts
severe
stress
on
the
governments
of
many
countries.
Unable to buy
grain or grow their own, hungry people take to the
streets. Indeed,
even before the steep
climb in grain prices in 2008, the number of
failing states was
expanding. If the
food situation continues to worsen, entire nations
will break down
at
an
ever
increasing
rate.
In
the
20th
century
the
main
threat
to
international
security was
superpower conflict; today it is failing states.
[D]
States
fail
when
national
governments
can
no
longer
provide
personal
security, food security and basic
social services such as education and health care.
When governments lose their control on
power, law and order begin to disintegrate.
After a point, countries can become so
dangerous that food relief workers are no
longer
safe
and
their
programs
are
halted.
Failing
states
are
of
international
concern
because they are a source of terrorists, drugs,
weapons and refugees(
难民
),
threatening political stability
everywhere.
[E] The surge in world grain prices in
2007 and 2008
—
and the threat
they pose
to food
security
——
has a different,
more troubling quality than the increases of the
past. During the second of the 20th
century, grain prices rose dramatically several
times.
In
1972,
for
instance,
the
Soviets.
I
recognizing
their
poor
harvest
early,
quietly cornered the
world wheat market. As a result, wheat prices
elsewhere more
than doubled, pulling
rice and com prices up with them. But this and
other price
shocks were event-
driven
——
drought in the
Soviet Union, crop-shrinking heat in
the
U.S.
Corn
Belt.
And
the
rises
were
short-
lived:
prices
typically
returned
to
normal with the next harvest.
[F]In
contrast,
recent
surge
in
world
grain
prices
is
trend-
driven,
making
it
unlikely to reverse without a reversal
in the trends themselves. On the demand side,
those trends include the ongoing
addition of more than 70 million people a year, a
growing number of people wanting to
move up the food chain to consume highly
grain-intensive meat products, and the
massive diversion(
转向
)of U.S.
grain to the
production of bio-fuel.
[G]As
incomes
rise
among
low-
income
consumers,
the
potential
for
further
grain
consumption
is
huge.
But
that
potential
pales
beside
the
never-
ending
demand for crop-based fuels. A
fourth of this year's U.S. grain harvest will go
to fuel
cars.
[H]What
about
supply?
The
three
environmental
trends
——
the
shortage
of
fresh
water,
the
loss
of
topsoil
and
the
rising
temperatures
——
are
making
it
increasingly hard to expand the world's
grain supply fast enough to keep up with
demand.
Of
all
those
trends,
however,
the
spread
of
water
shortages
poses
the
most immediate threat.
The biggest challenge here is irrigation, which
consumes
70% the world's fresh water.
Millions of irrigation wells in many countries are
now
pumping water out of underground
sources faster than rainfall can refill them. The
result
is
falling
water
tables(
地下水位
)in
countries
with
half
the
world's
people,
including the three
big grain producers
——
China,
India and the U.S.
[I]As water tables have
fallen and irrigation wells have gone dry, China's
wheat
crop, the world's largest, has
declined by 8% since it peaked at 123 million tons
