Comprehension ( 40 minutes )

Directions:There are 2
passages in this section. Each
passage
is followed by some questions or unfinished
statements.
For each of them there are
four choices marked A), B), C) and
D).
You should decide on the best choice and mark the
corresponding letter on Answer Sheet
2with a single line

centre.
Passage One
Questions 46 and 50 are
based on the following passage.
Aging happens
to all of us, and is generally thought of as
a natural part of life. It would seem
silly to call such a
thing a
“
disease.
”
On the other
hand, scientists are increasingly learning
that aging and biological age are two
different things, and
that the former
is a key risk factor for conditions such as
heart disease, cancer and many more. In
that light, aging
itself might be seen as something
treatable, the way you would
treat high
blood pressure or a vitamin deficiency.
Biophysicist
Alex Zhavoronkov believes that aging should be
considered a disease. He said that
describing aging as a
disease creates
incentives to develop treatments.
“
It
unties the hands of the
pharmaceutical(
制药的
)industry
so that they can begin treating the
disease and not just the
side
effects,
”
he said.
“
Right now, people think of
aging as natural and something
you
can
’
t
control,
”
he said.
“
IN academic circles, people
take aging research as just an interest
area where they can try
to develop
interventions. The medical community also takes
aging for granted, and can do nothing
about it except keep
people within a
certain health range.”
But if aging were
recognized as a disease, he
said,
“
It
would
attract funding and change the way we do health
care.
What matters is understand that
aging is curable.
”
“
It
was always known that the body accumulates
damage,
”
he
added.
“
The only way to cure aging
is to find ways to repair
that damage. I think of it as
preventive medicine for age-
related
conditions.
”
Leonard Hayflick, a
professor at the University of
California, San Francisco, said the
idea that aging can be
cured implies
the human lifespancan be increased, which some
researchers suggest is possible.
Hayflick is not among them.
“
There
’
re many people who recover from
cancer, stroke, or
heart disease. But
they continue to age, because aging is
separate from their
disease,
”
Hayflick said.
“
Even if those
causes of death were eliminated, life
expectancy would still
not go much
beyond
92 years.”
46. Whatdo
people generally believe about aging
A) It should
cause not alarm whatsoever.
B) They just cannot do
anything about it.
C) It should be regardedas
a kind of disease.
D) They can delay it with
advances in science.
do many scientists view
aging now
A) It might be
prevented and treated. C) It results from a
vitamin deficiency.
B) It can be as
risky as heart disease. D) It is an
irreversible biological
process.
48. What does Alex Zhavoronkov think of
“
describing aging
as a disease
”
A) It will
prompt people to take aging more
seriously.
B) It will greatly help reduce the side
effects of aging.
C) It will free pharmacists
from the conventional beliefs
about
aging.
D) It will motivate doctors and
pharmacists to find ways to
treat
aging.
49. What do we learn about the medical
community
A) They now have a strong interest in
research on aging.
B) They differ from the
academic circles in their view on
aging.
C) They can contribute to
people
’
s health only to a
limited extent.
