Cloning（克隆）:Future Pertect?
1 A clone is an exact copy of a plant or animal produced from any one cell.Since Scottish
scientists reported that they had managed to clone a sheep named Dolly in 1997,research
into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to
create two identical calves（牛犊）using cloning technology. A mouse has also been
cloned successfully.But the debate over cloning humans really started when Chicago
physicist Richard Seed made a surprising announcement:"We will have managed to clonen
a human being within the next two years."he told the world.
2 Seed's announcement provoked a lot of media attention,most of it negative.In Europe,
nineteen nations have already signed an agreement banning human cloning and in the U.S.
the President announced:"We will be introducing a law to ban all human cloning and many
states in the U.S. will have passed anti-cloning laws by the end of the year."
3 Many researchers are not so negative about cloning.They are worried that laws banning
human cloning will threaten important research.In March,The New England
Joumal of
Medicine called any plan to ban research on cloning humans seriously mistaken.Many
researchers also believe that in spite of attempts to ban it,human cloning will have become
routine by 2010 because it is impossible to stop the progress of science.
4 Is there reason to fear that cloning will lead to a nightmare world?The public has been
bombarded（轰炸）with newspaper articles , television shows and films , as well as
cartoons.Such information is often misleading,and makes people wonder what on earth
the scientists will be doing next.
5 Within the next five to ten years scientists will probably have found a way of cioning
humans.It could be that pretty soon we will be able to choose the person that we want our
child to look like.But how would it feel to be a clone among hundreds,the anti-cloners
ask. Pretty cool , answer the pro-cloners（赞成克隆的人）.

共用题干Clone FarmFactory farming could soon enter a new era of mass production .Companies in the US are developing the technology needed to"clone"chickens on a massive scale.Once a chicken with desirable traits has been bred or genetically engineered,tens of thousands of eggs,which will hatch into identical copies,could roll off the production lines every hour. Billions of clones could be produced each year to supply chicken farms with birds that all grow at the same rate,have the same amount of meat and taste the same.This,at least,is the vision of the US's National Institute of Science and Technology,which has given Origen Therapeutics of Burlingame,California,and Embrex of North Carolina $4 .7 million to help fund research.The prospect has alarmed animal welfare groups,who fear it could increase the suffering of farm birds.That's unlikely to put off the poultry industry,however,which wants disease-resistant birds that grow faster on less food."Producers would like the same meat quantity but to use reduced inputs to get there,"says Mike Fitzgerald of Origen.To meet this demand,Origen aims to"create an animal that is effectively a clone",he says.Normal cloning doesn't work in birds because eggs can't be removed and implanted.Instead,the company is trying to bulk-grow embryonic stem cells taken from fertilized eggs as soon as they're laid."The trick is to culture the cells without them starting to distinguish,so they remain pluripotent,"says Fitzgerald.Using a long-established technique,these donor cells will then be injected into the embryo of a freshly laid,fertilized recipient egg,forming a chick that is a"chimera".Strictly speaking a chimera isn't a clone,because it contains cells from both donor and recipient. But Fitzgerald says it will be enough if,say,95 percent of a chicken's body develops from donor cells."In the poultry world,it doesn't matter if it's not 100 percent."he says.Another challenge for Origen is to scale up production .To do this,it has teamed up with Embrex,which produces machines that can inject vaccines into up to 50,000 eggs an hour. Embrex is now trying to modify the machines to locate the embryo and inject the cells into precisely the right spot without killing it.In future,Origen imagines freezing stem cells from different strains of chicken.If orders come in for a particular strain,millions of eggs could be produced in months or even weeks.At present, maintaining all the varieties the market might call for is too expensive for breeders and it takes years to bread enough chickens to produce the billions of eggs that farmers need. Which institution has offered $4 .7 million to fund the research?A: The US's National Institute of Science and Technology.B: Origen Therapeutics of Burlingame,California.C: Embrex of North Carolina.D: Animal welfare groups.

共用题干That scientists have cloned a sheep sends academics and the public into a panic at the prospect that humans might be next. That's an understandable reaction.(46)___________,so it's not unreasonable to be concerned that it might threaten human society and dignity.Yet much of the ethical oppo-- sition seems also to grow out of an unthinking disgust. And that makes it hard for even trained scientists and ethicists to see the matter clearly.While human cloning might not offer great benefits to humarnty,no one has yet made a persuasive case that it would do any real harm,either.(47)_______That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower stature.But why suppose that cloned persons wouldn't share the same rights and dignity as the rest of us?A leading ethicist has suggested that cloning would violate the "right to genetic identity".(48)________It makes perfect sense to say that adult persons have a right not to be cloned without their voluntary,informed consent. But if such consent is given,whose "right"to genetic identity would be violated?So who will likely take advantage of cloning?Perhaps a grieving couple whose child is dying. (49)________But a cloned child born to such dubious parents stands no greater or lesser chance of being loved,or rejected,or warped than a child normally conceived.Infertile couples are also likely to seek out cloning. That such couples have other options(in vitro fertilization or adoption)is not an argument for denying them the right to clone.Or consider an example raised by Judge Richard Posner:a couple in which the husband has some tragic genetic defect. Currently,if this couple wants a genetically related child,(50)________They can reproduce naturally and risk passing on the disease to the child.They can go to a sperm bank and take a chance on unknown genes.They can try in vitro fertilization and dispose of any afflicted embryo though that might be objectionable,too.Or they can get a male relative of the father to donate sperm,if such a relative exists.This is one case where even people unnerved by cloning might see it as not the worst option.Even if human cloning offers no obvious benefits to humanity,why ban it?In a democratic society we don't usually pass laws outlawing something before there is actual or probable evidence of harm.Most important,human cloning should be governed by the same laws that now protect human rights.A world not safe for cloned humans would be a world not safe for the rest of us._______（49）A:they have four not altogether pleasant options.B:This might seem psychologically twisted.C:Theologians contend that to clone a human would violate human dignity.D:Parents might clone a child to have"spare parts"in case the original child needs an organ transplant.E:Cloning is a radical challenge to the most fundamental laws of biology.F: Where did he come up with such a right?

共用题干第一篇The Mystery of ClonesScientists 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.

问答题Practice 3 Dolly was no ordinary lamb. She was cloned from a single mammary cell of an adult ewe, overturning long- held scientific dogma that had declared such a thing biologically impossible. Her birth set off a race in laboratories around the world to duplicate the breakthrough and raised the specter of human cloning. A decade later, scientists are starting to come to grips with just how different Dolly was. Dozens of animals have been cloned since that first little lamb and it’s becoming increasingly clear that they are all, in one way or another, defective. It’s tempting to think of clones as perfect carbon copies of the original—down to every hair and quirk of temperament. It turns out, though, that there are various degrees of genetic replication. Not only are clones separated from the original template by time—-in Dolly’s case, six years—but they are also the product of an unnatural molecular mechanism that turns out not to be very good at making identical copies. But scientists see a role for cloning in treating human diseases—and perhaps someday conquering some of man’s most intractable conditions. It may be another 10 years or more before the approach yields anything safe and reliable enough to be used in real patients, and there is no guarantee that it will ever be successful. But nobody thought Dolly was possible until she made history that warm July night 10 years ago.
问答题Practice 1 After nearly a year of emotional arguments in Congress but no new federal laws the national debate over the future of human cloning has shifted to the states. Six states have already banned cloning in one form or another，and this year alone 38 anticloning measures were introduced in 22 states. The resulting patchwork of laws，people on all sides of the issue say，complicates a nationwide picture already clouded by scientific and ethnical questions over whether and how to restrict cloning or ban it altogether. Since l997，when scientists announced the birth of Dolly the sheep，the first cloned mammal，the specter of cloned babies, infants that ate，in essence，genetic carbon copies of adults has loomed large in the public psyche and in the minds of lawmakers. Today, there is widespread agreement that cloning fur reproduction is unsafe and should be banned. Now，the debate has shifted away from the ethics of baby-making and toward the morality of cloning embryos for their cells and tissues，which might be used to treat diseases. The controversy pits religious c6nservatives and abortion opponents, who regard embryos as nascent human life，against patients' groups，scientists and the biotechnology industry.
问答题Passage 2 A new form of cloning to provide every baby with an embryonic “twin”, from which spare body parts could be grown and life threatening diseases treated is expected to be approved within weeks by senior government advisers on medical ethics. If their report is accepted by ministers, it would mean that Britain—which 20 years ago pioneered the test tube baby and last year produced Dolly, the world’s first cloned mammal—could be the first to clone a human embryo. A working party from the Human Fertilisation and Embryology Authority (HFEA) and the Human Genetics Advisory Commission is expected to come down firmly against reproductive cloning, the process of replicating a living human being. It is expected to recommend government support of so called stem ceils. Stem cells are extracted and used to grow spare parts, treat diseases such as Alzheimer’s and Parkinson’s or address the debilitating effects of cancer, strokes and heart attacks. Dr Austin Smith, the scientist likely to be granted the first licence for the work, said that within the next 12 years it would be routine for every baby to have an embryonic clone. “All it takes now is financial investment,” said Smith, director of Edinburgh University’s centre for genome research. The crucial discovery of embryonic stem cells, from which skin, bone, muscles, nerves and vital organs grow, was made earlier this month by scientists in America. In a submission to the HFEA, Smith said that in order to isolate these cells it is only necessary for the embryo to develop in the laboratory for six days, well within the 14-day limit of current regulation. The cells would then be grown and manipulated to make anything from blood or brain cells to tissue for repairing damaged organs and, ultimately, parts that could be transplanted without fear of the host body rejecting them. The development is likely to meet strong opposition from the church. Dr Donald Bruce, Director of the Society, Religion and Technology Project of the church of Scotland Said that creating an embryo in the knowledge that it would then be destroyed was “very disturbing” to most people. Father Paul Murray, secretary to the Catholic bishops joint bio-ethics committee, said that whatever the potential benefits, it should be regarded as “intrinsically evil” because the research depended on the use of foetal material. However, Professor Christine Gosden, professor of genetic medicine at Liverpool University, one of the four senior government advisers on the cloning sub-committee, said there would be no opportunity for abuse. For many years, patients with Parkinson’s disease who did not respond to drugs have been treated with brain cells extracted from aborted foetuses, a practice approved by a committee led by the Rev Dr John Polkinghorne, the prominent ethicist. Gosden said the arguments for the use of aborted foetal cells and therapeutic cloning were similar: “Before you have a disease, it is easy to say, ‘I would not use cells derived from a foetus’, but if you suffer from that disease, and that is your only hope, your approach can be quite different.” 1. What is the new form of cloning discussed in the passage? What is the purpose of such cloning? 2. Summarise the different views on embryo cloning discussed in the passage. 3. Explain the statement “All it takes now is financial investment.” in para. 6. 4. What is the significance of the discovery of embryonic stem cells?
