from the four choices marked A),B),C)and D. For questions 8-10,complete the
sentences with the information given in the passage. What
will the world be like in fifty years? This
week some top scientists, including Nobel Prize winners, gave their vision of
how the world will look in 2056,fron gas-powered cars to extraordinary health
advances, John Ingham reports on what the world’s finest minds believe our
futures will be. For
those of us lucky enough to live that long,2056 will be a world of almost
perpetual youth, where obesity is a remote memory and robots become our
companions. We
will be rubbing shoulders with aliens and colonizing outer space. Better still,
our descendants might at last live in a world at peace with itself. The
prediction is that we will have found a source of inexbaustible, safe, green
energy, and that science will have killed off religion. If they are right we
will have removed two of the main causes of war-our dependence on oil and
religious prejudice. Will
we really, as today’s scientists claim, be able to live for ever or at least
cheat the ageing process so that the average person lives to 150? Of
course, all these predictions come with a scientific health warning. Harvard
professor Steven Pinker says: “This is an invitation to look foolish, as with
the predictions of domed cities and nuclear-powered vacuum cleaners that were
made 50 year ago.” Living
longer Anthony
Atala, director of the Wake Forest Institute in North Carolina, belives failing
organs will be repaired by injecting cells into the body. They will naturally
to straight to the injury and help heal it. A system of injections without
needles could also slow the ageing process by using the same process to “tune”
cells. Bruce
Lahn, professor of human genetics at the University of Chicago, anticipates the
ability to produce“unlimited supplies” of transplantable human organs without
the needed a new organ, such as kidney, the surgeon would contact a commercial
organ producer, give him the patient’s immuno-logical profile and would then be
sent a kidney with the correct tissue type. These
organs would be entirely composed of human cells, grown by introducing them
into animal hosts, and alloweing them to deveoop into and organ in place of the
animal’s own. But Prof. Lahn believes that farmed brains would be “off
limits”.He says: “Very few people would want to have their brains replaced by
someone else’s and we probably don’t want to put a human brain ing an animal
body.” Richard
Miller, a professor at the University of Michigan, thinks scientist could
develop“an thentic anti-ageing drugs” by working out how cells in larger
animals such as whales and human resist many forms of injuries. He says:“It’s
is now routine, in laboratory mammals, to extend lifespan by about 40%. Turning
on the same protective systems in people should, by 2056, create the first
class of 100-year-olds who are as vigorous and productive as today’s people in
their 60s” Aliens Conlin
Pillinger ,professor of planerary sciences at the Open University,says:”I fancy
that at least we will be able to show that life didi start to evolve on Mars
well as Earth.”Within 50years he hopes scientists will prove that alien life
came here in Martian meteorites(陨石). Chris
McKay,a planetary scientist at NASA’s Ames Research Center.believes that in 50
years we may find evidence of alien life in ancient permanent forst of Mars or
on other planers. He
adds:”There is even a chance we will find alien life forms here on Earth.It
mightbe as different as English is to Chinese. Priceton
professor Freeman Dyson thinks it “likely” that life form outer space will be
discovered defore 2056 because the tools for finding it, such as optical and
radio detection and data processing,are improving. He
ays:”As soon as the first evidence is found,we will know what to look for and
additional discoveries are likely to follow quickly.Such discoveries are likely
to have revolutionary consequences for biology, astronomy and philosophy. They
may change the way we look at ourselves and our place in the universe. Colonies
in space Richard
Gottprofessor of astrophysics at Princeton,hopes man will set up a self-sufficient
colony on Mars,which would be a “life insurance policy against whatever
catastrophes,natural or otherwise,might occur on Earth. “The
real space race is whether we will colonise off Earth on to other worlds before
money for the space programme runs out.” Spinal
injuries Ellen
Heber-Katz,a professor at the Wistar Institude in Philadelphia,foresees cures
for inijuries causing paralysis such as the one that afflicated Superman star
Christopher Reeve. She
says:”I believe that the day is not far off when we will be able to profescribe
drugs that cause severes(断裂的)
spinal cords to heal,hearts to regenerate and lost limbs to regrow. “People
will come to expect that injured or diseased organs are meant to be repaired
from within,inmuch the same way that we fix an appliance or automobile:by
replancing the damaged part with a manufacturer-certified new part.”She predict
that within 5 to 10 years fingers and toes will be regrown and limbs will start
to be regrown a few years later. Reparies to the nervous system will start with
optic nerves and,in time,the spinal cord.”Within 50years whole body replacement
will be routine,”Prof.Heber-Katz adds. Obesity Sydney
Brenner,senior distinguished fellow of the Crick-Jacobs Center in
California,won the 2002 Noblel Prize for Medicine and says that if there is a
global disaster some humans will survive-and evolition will favour small people
with bodies large enough to support the required amount of brain
power.”Obesity,”he says.”will have been solved.” Robots Rodney
Brooks,professor of robotice at MIT,says the problems of developing artificial
intelligence for robots will be at least partly overcome.As a result,”the
possibilities for robots working with people will open up immensely” Energy Bill
Joy,green technology expert in Califomia,says:”The most significant
breakthrought would be to have an inexhaustible source of safe,green energy
that is substantially cheaper than any existing energy source.” Ideally,such
a source would be safe in that it could not be made into weapons and would not
make hazardous or toxic waste or carbon dioxide,the main greenhouse gas blamed
for global warming. Society
Geoffrey Miller,evolutionary psychologist at the University of New
Mexico,says:”The US will follow the UKin realizing that religion is nor a
prerequisite (前提)for ordinary
human decency.
“This,science will kill religion-not by reason challenging faith but by
offering a more practical,uniwersal and rewarding moral frameworkfor human
interaction.”
He also predicts that “ahsurdly wasteful”displays of wealth will become
umfashionable while the importance of close-knit communities and families will
become clearer.
These there changer,he says,will help make us all”brighe\ter,wiser,happier and
kinder”. 注意:此部分试题请在答题卡1上作答。 1.What
