The Science of the Future

Until recently,the"science of the future"was supposed to be electronics and
artificial intelligence.Today it seems more and more likely that the next great
breakthroughs in technology will be brought through a combination of those two sciences
with organic chemistry and genetic engineering.This combination is the science of
biotechnology.
Organic chemistry enables us to produce marvelous synthetic（合成的）materials.
However,it is still difficult to manufacture anything that has the capacity of wool to conserve
heat and also to absorb moisture.Nothing that we have been able to produce so far comes
anywhere near the combination of strength,lightness and flexibility that we find in the bodies
of ordinary insects.
Nevertheless,scientists in the laboratory have already succeeded in"growing"a
material that has many of the characteristics of human skin.The next step may well be
"biotech hearts and eyes"which can replace diseased organs in human beings.These will
not be rejected by the body,as is the case with organs from humans.
The application of biotechnology to energy production seems even more promising.In
1 996 the famous science-fiction writer,Arthur C. Clarke,many of whose previous
predictions have come true,said that we may soon be able to develop remarkably cheap
and renewable sources of energy.Some of these power sources will be biological.Clarke
and others have warned us repeatedly that sooner or later we will have to give up our
dependence on non-renewable power sources.Coal,oil and gas are indeed convenient.
However,using them also means creating dangerously high levels of pollution.It will be
impossible to meet the growing demand for energy without increasing that pollution to
catastrophic（灾难性的）levels unless we develop power sources that are both cheaper and
cleaner.
It is attempting to think that biotechnology or some other"science of the future"can
solve our problems.Before we surrender to that temptation we should remember nuclear
power.Only a few generations ago it seemed to promise limitless,cheap and safe energy.
Today those promises lie buried in a concrete grave in a place called Chernobyl,in the
Ukraine.Biotechnology is unlikely,however,to break its promises in quite the same or
such a dangerous way.

According to the passage,the science of the future is likely to be
A:electronics.
B:biotechnology.
C:genetic engineering.
D:nuclear technology.

Are These Food Safe to Eat?

Traditionally,in plant breeding,there are crossing varieties of the same species in ways they could cross naturally.For example,disease-resistant varieties of wheat have been crossed with highyield wheat to combine these properties.This type of natural gene exchange is safe and fairly predictable.
Genetic engineering(GE)makes it possible to exchange genes between unrelated species that cannot exchange genes with each other in a natural way.GE can involve the exchange of genes be-tween vastly different species一e.g. putting scorpion toxin genes into maize or fish antifreeze genes into tomatoes.It is possible that a scorpion toxin gene,even when it is in maize DNA,will still get the organism to produce scorpion toxin一but what other effects may it have in this alien environment? We have already realized this problem一adding human growth hormone genes to pigs certainly makes them grow一but it also gives them arthritis and makes them cross-eyed,which was entirely out of expectation.
It won't be difficult to find out,for example,that the gene for human intelligence will not have the same effect if it is inserted into cabbage DNA as it had in human DNA一but what side-effect would it have?In other words,is genetically modified(GM)food safe to eat?The answer is that no-body knows because long-term tests have not been carried out.
Those companies who want a GM product approved in the UK or USA are required to provide regulatory bodies with results of their own safety tests.Monsanto's soya beans were apparently fed to fish for 10 weeks before being approved.There was no requirement for independent testing,for longterm testing,for testing on humans or testing for specific dangers to children or allergic people.
The present opinion of the British Government is that"There is no evidence of long-term dangers from GM foods."In the US,the American Food and Drug Administration is now being prosecuted for covering up research that suggested possible risks from GM foods.

Which statement about GM product is true according to the passage?
A:Adding human growth hormone genes to pigs does not make them grow.

Among all the fast growing science and technology,the research of human genes,or biological engineering
as people call it,is drawing more and more attention now,Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure some serious diseases.Doctors at present can
almost do nothing with them.Cancer and heart disease are the examples.______________(46)
And to date,doctors have not found an effective way to cure them.But if the gene technology is applied,
these two diseases can be cured completely,bringing happiness and more living days to the patients.
_____________(47)
Gene technology can help people to give birth to more healthy and clever children.Some families,with
the English imperial family being a good example , have hereditary（遗传的）diseases._____________ (48 ) This
is a great trouble for these families.In the past,doctors could do nothing about the hereditary diseases.But
gene technology can solve this problem perfectly.______________(49)
Some people are worrying that the gene research can be used to manufacture human beings in large
quantities.In the past few years,scientists have succeeded in cloning a sheep,so these people predict that
human babies would soon be cloned._____________(50)Of course,the governments must take care to control
gene technology.

_________（47）
A:Every year,millions of people are murdered by these two diseases.
B:But I believe cloned babies will not come out in large quantities,for most couples in the world can havebabies in very normal way.
B:This means their children will for sure have the family disease.
C:The scientists just need to find the wrong gene and correct it,and a healthy child will be born.
E:In addition,the great amount of money people spend on curing their diseases can be saved,and it benefitst he economy as well.

Can Gene Technology Make Human Smarter?

Almost everyone wants to get smarter. To achieve that,some choose to do exercise,others choose to take in more nutritions good for brains.Princeton neurobiologist Joseph Z.Tsien possibly found a different way to make it. In September he announced that he'd built a better mouse by altering a gene that affects learning and memory.A similar process of gene manipulation might conceivably be used one day to boost intelligence in humans.
The key of this technology lies in a feature of brain cells called the NMDA receptor,which Tsien likens to a cylindrical tube or window that mediates the flow of information.When the window is open,chemicals called neurotransmitters flow through easily and memory is registered and stored. But as organisms mature,the window begins to close.(This may explain why children lose their facility for learning new languages when they reach sexual maturity and why some people suffer memory loss as they age.)
Tsien also found out that the receptor worked more efficiently if it is teamed with the gene NR2B,so he introduced extra NR2B genes into a batch of fertilized mouse eggs.In a normal mouse,the memory window is open for just 150-thousandths of a second.In Tsien's specially engineered mice,the window opens for 250-thousandths of a second,long enough to make a remarkable difference in memory retention.When he pitted his mice against common mice,they won paws down.Ordinary mice could recognize a Lego block for 12 hours,but smart mice could remember the block for up to three days."That's a profound enhancement,"Tsien says.
Can this technology be applied to humans?Maybe,but genetic engineering will have to make some extraordinary advances first. And some thorny ethical issues will have to be resolved. Mean-while,Tsien promises to keep his furry little geniuses locked up in a lab,far from your larder. "Otherwise,"he says,"you might need a smart cat or a smart mousetrap to catch them."

What problems must be solves before this technology is applied to human?
A:Gene must be conceivably manipulated.
B:Genetic engineering will have to make some extraordinary advances first and some thorny ethical issues will have to be resolved.
C:NMDA receptor is teamed with the gene NR2B.
D:The smart nice must be locked up in a lab.
