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）.

Within ten years scientists will probably have______.
A:the nucleus of a cell
B:cloned human beings
C:a human being in two years
D:a law to ban human cloning
E:a report on human cloning
F:heavy media coverage

第3题：

Why would a clone not be identical to the "master copy"?

A、They are totally different persons.

B、The clone's cells, for example, would have energy-processing machinery that came from the egg, not from the person who was cloned.

C、They have different genetic source.

D、The clone’s cells can be productive.

第6题：

We may conclude from the text that _____.

［A］ human cloning will not succeed unless the technique is more efficient

［B］ scientists are optimistic about cloning technique

［C］ many people are against the idea of human cloning

［D］ cloned animals are more favored by owners even if they are weaker

正确答案：A

本题考查全局事实细节题。文章一开始就引用专家威斯苏森的话，指出克隆人是愚蠢的尝试。第二段最后两句提到，克隆实验的低效性和危险性在克隆人中不可接受。文章末尾再次引用该专家的话，指出现在动物的研究还没成功，没有必要想到克隆人。由此可见，技术是克隆实验存在的主要问题，也是阻碍克隆人实验的重要原因，因此可推知［A］正确。［B］明显错误，科学家并不乐观。全文只涉及专家和拥护克隆实验的人的观点，因此无从推知［C］。［D］在文中未提及。

Clone Farm
Factory 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.

答案：A

解析：

第一段最后一句提供了直接的答案。

第二段共提到三个研究机构和一个民间组织。the US's National Institute of Science and Technology为研究提供了经费，被资助的研究机构是Origen Therapeutics of Burlingame, California和Embrex of North Carolina。因此，A是答案。

原句的意思有两点是关键的，即每只鸡提供的肉量不变，但饲料（inputs）要减少。只有D符合原意。

该段第二句中which引导的从句表明，是Embrex生产疫苗注射装置，而不是两家研究单位共同研制。Embrex在此基础上将装置改造为细胞注射装置。所以，只有C最接近原意。

第六段的大意是，如果能冷冻所有品种的鸡的干细胞，那么，无论需要什么品种的鸡蛋或多少数量，都不是问题。但是，目前储备所有品种是非常昂贵的。B、C、D从几个方面表达了这层意思。因此，只有A是答案。

第10题：

The United States will introduce_______.
A:the nucleus of a cell
B:cloned human beings
C:a human being in two years
D:a law to ban human cloning
E:a report on human cloning
F:heavy media coverage

答案：D
