Who Want to Live Forever?
If your doctor could give you a drug that would let you live a healthy life for twice as long,would you take it?
The good news is that we may be drawing near to that date.Scientists have already extended the lives of flies,worms and mice in laboratories.Many now think that using genetic treatments we will soon be able to extend human life to at least 140 years.
This seems a great idea.Think of how much more time we could spend chasing our dreams,spending time with our loved ones,watching our families grow and have families of their own.
"Longer life would give us a chance to recover from our mistakes and promote long term thinking," says Dr.Gregory Stock of the University of California School of Public Health."It would also raise productivity by adding to the year we can work."
Longer lives don't just affect the people who live them.They also affect society as a whole."We have war,poverty,all sorts of issues around,and I don't think any of them would be at all helped by having people live longer,"says US bioethicist Daniel Callahan."The question is‘What will we get as a society?'I suspect it won't be a better society."
It would certainly be a very different society.People are already finding it more difficult to stay married.
Divorce rates are rising.What would happen to marriage in a society where people lived for 140 years?And what would happen to family life if 9 or 10 generations of the same family were all alive at the same time? Research into ageing may enable women to remain fertile for longer.And that raises the prospect of having 100-year-old parents,or brothers and sisters born 50 years apart.We think of an elder sibling as someone who can protect us and offer help and advice.That would be hard to do if that sibling came from a completely different generation.
Working life would also be affected,especially if the retirement age was lifted.More people would stay in work for longer.That would give us the benefits of age-skill,wisdom and good judgment.
On the other hand,more people working for longer would create greater competition for jobs.It would make it more difficult for younger people to find a job.Top posts would be dominated by the same few individuals,making career progress more difficult.And how easily would a 25 -year-old employee be able to communicate with a 1 25 -year-old boss?
Young people would be a smaller part of a society in which people lived to 140.It may be that such a society would place less importance on guiding and educating young people,and more on making life comfortable for the old.
And society would feel very different if more of its members were older.There would be more wisdom, but less energy.Young people like to move about.Old people like to sit still.Young people tend to act without thinking.Old people tend to think without acting.Young people are curious and like to cxperience different things.Old people are less enthusiastic about change.In fact,they are less,enthusiastic about everything.
The effect of anti一ageing technology is deeper than we might think.But as the science advances,we need to think about these changes now.
"If this could ever happen,then we'd better ask what kind of society we want to get,"says Daniel Callahan."We had better not go anywhere near it until we have figure those problems out."

Which of the following is implied in the sixth paragraph?
A:Marriages in the US today are quite unstable.
B:More and more people in the US today want to get married.
C:Living longer would make it easier for people to maintain their marital ties.
D:If people live longer,they would stay in marriage longer.

Mad Scientist Stereotype Outdated

Do people still imagine a physicist as a bearded man in glasses or has the image of the
mad scientist changed?The Institute of Physics set out to find out whether the stereotype of
a physics"boffin"（科学家）still exists by conducting a survey on shoppers in London. The
people were asked to identify the physicist from a photograph of a line-up of possible
suspects.98 percent of those asked got it wrong.The majority of people picked a white
male of around 60,wearing glasses and with a white beard.
While this stereotype may have been the image of an average physicist fifty years ago,
the reality is now very different. Since 1 960 the number of young women entering physics
has doubled and the average age of a physicist is now 31.
The stereotype of the absent-minded scientist has lasted a long time because the media
and Hollywood help promote the image of men in white lab coats with glasses sitting by
blackboards full of equations（等式）or working with fizzing（嘶嘶响）test tubes. These
stereotypes are really damaging to society.Very good school children are put off studying
science because they don't see people like themselves on television or in magazines doing
science.They simply don't relate to the media's image of the mad scientist.
This is one reason why fewer young people are choosing to do science at university.If
we want to encourage more young people to study science subjects,we need to change
this image of the scientist and make science careers more attractive.But we must also
develop children's interest in science.
In an attempt to change this negative image,an increasing number of science festivals
are being organized.Thousands of people from secondary schools are also encouraged to
take part in nationwide science competitions of which the most popular are the national
science Olympiads.Winning national teams then get the opportunity to take part in the
International Science Olympiads which are held in a different country every year.These
events are all interesting for the young people who take part but they only involve a small
proportion of students who are already interested in science.It seems that there is a long
way to go before science becomes attractive as subjects like computer studies or fashion
and design.

Most people have similar ideas of what a physicist looks like.
A:Right
B:Wrong
C:Not mentioned

Changes in Museums
Museums have changed.They are no longer places that one"should"visit;they are places to enjoy and learn.
At a science museum in Ontario,Canada,you can feel your hair stand on end as harmless electricity passes through your body.At the Metropolitan（大城市的）Museum of Art in New York City , you can look at the seventeenth century instruments while listening to their music.At New York's American Museum of Natural History recently,you can help make a bone-by- bone reproduction of the museum's dinosaur（恐 龙）,a beast that lived 200 million years ago.
More and more museum directors are realizing that people learn best when they can somehow become part of what they are seeing.In many science museums,for example,there are no guided tours.The visitor is encouraged to touch,listen,operate,and experiment so as to discover scientific principles for himself. The purpose is not only to provide fun but also to help people feel at home in the world of science.The theory is that people who do not understand science will probably fear it,and those who fear science will not use it to best advantage.
One cause of all these changes is the increase in wealth and leisure time.Another cause is the rising percentage of young people in the population.Many of these young people are college students or college graduates.Leon F.Twiggs,a young black professor of art once said,"They see things in a new and different way.They are not satisfied to stand and look at works of art;they want art they can participate（参加）in."The same is true of science and history.

People can afford to get into the modern museums since they have more time now.
A:Right
B:Wrong
C:Not mentioned

The Mystery of Clones

Scientists have cloned goats,cats,cows,pigs and mice.Now it has been suggested by many commentators and scientists that it might be ethically acceptable to clone existing people in certain cases.One possibility is generating a replacement for a dying relative.All such possibilities,however,makes more and more people concerned that it would be possible that the clone is subjected to expectations and limitations based on the family's knowledge of the genetic"twin",so he or she would not be treated as an individual with independent personality.For the reason that human personality is only partly determined by genes,those assumptions might not be right.The clone of a shy person might behave quite differently if he or she is brought up in a family with encouraging atmosphere.Clones of writers,scholars,scientists or athletes are very likely to choose different careers because of chance event in early life.
Some researchers have suggested the idea that couples,in which one part is infertile,might choose to make a copy of one or the other partner. But the notion raises the concerns that the child who is a copy of just one of a couple might not treat naturally,and it is not in the interests of the resulting kid.Moreover,the treatments of all known types of infertility are available nowadays;conventional therapies seem more ethnically acceptable to ordinary people's way of thinking,so the majority of population strongly opposed to allowing cloned human embryos（胚胎）to develop.
However,the positive side of the cloning technology cannot be denied,for instance,cloning from cultured cells will provide essential medical opportunities.Scientists are trying to grow an embryo,cloned from a single cell of a human being with goals to design therapies for diseases which are currently untreatable.
Of course,people's predictions about this new technology might be all wrong,because social attitudes change and unexpected developments take place.Only time will tell.But biomedical researchers who are dedicated to finding the potential of cloning have plenty to do.Maybe someday soon,a human will be cloned,and mankind will embark on a scientific and moral journey whose destination is not under his own control. Or maybe one day you will be happy to have a clone of your own.

What is people's concern about cloning a child for infertile couples?
A:The child might not be treated kindly.
B:It's not for the good of the resulting child.
C:The couples would not accept the resulting child.
D:It would be wild to have a clone of one's own.

According to the author，what may“image- based communication”influence voter’s behavior？( )

A.People might vote on their identities.
B.People might vote on their“hidden mental hunters”
C.People might vote on arguments，independent of identity.
D.People might vote on political advertisers who have better stories.
