2、ers at Texas A&M University created the clone from the DNA of a calico cat(三色猫) named Rainbow after a failed attempt at cloning a dog.Interestingly, Rainbow and Copy Cat are different in many ways.Rainbows coat is brown, and white, while CCs is gray and white; Rainbow is shy, but CC is outgoing and
3、curious. The differences in the two cats indicate that identical DNA wont necessarily create similar appearances or personalities because there are many other factors that contribute to both surface characteristics and temperament(性情)CC has since gone on to have three healthy kittens via the natural
4、 method, and the research that led to her creation became the foundation for a Californiabased pet cloning company called Genetic Savings & Clone, Inc.However, the cat cloning project caused criticism from animal welfare groups, which pointed out that millions of cats are killed in shelters each yea
5、r due to pet overpopulation.They argued that the large sums of money spent on creating more cats could be put to better use providing homes for strays.There are also objections to the cloning process itself.Many people consider cloning cruel, as it is a process that can lead to deformities and other
6、 problems, which is evident in the fact that many clones die within months or even days of creation.Much to the delight of animal welfare advocates, after cloning five cats in total, Genetic Savings & Clone shut down in 2006.The reason for the companys close was its inability to make its cloning tec

9、as Rainbow.D细节理解题。根据文中第三段“The differences in the two cats indicate that identical DNA wont necessarily create similar appearances or personalities”即可判断答案。3Whats the underlined word in the 6th paragraph similar to?ACriticism.BWaste of money.CDisability.DOverpopulation.C词义猜测题。根据文中第六段“cruel”，“other pro
10、blems”和“which is evident in the fact that many clones die within months or even days of creation”可判断许多人认为克隆残酷会造成残疾和许多问题，甚至出现死亡，因此画线词指的是身体上的残疾。4The reason for the companys demise is that cloning is Aa waste of moneyBcruel sometimesCinaccessible to most peopleDaffordable to consumersC细节理解题。根据文章最后一段“.i
11、ts inability to make its cloning technology affordable and thus accessible to mainstream consumers.”可判断答案。BPeter Onruang，a Hollywood businessman，has paid $310，000 to clone his best friend Wolfie，a lovely dog.He said，“Wolfie was more than just a pet to me.” Wolfie died two years ago，at the age of 15.
12、But long before she and her sister Bubble passed away，Onruang had plans to bring them back to life.Onruang said，“I buried them at home.Each time I visit them，I say，Hi，Im making a new body for you.”Finally，Onruang found the South Korean biotechnology company RNL Bio，which can and will clone animals.O
13、nruang collected his dogs stem cells (干细胞)，and then he started a website My Friend A，so he could earn and save the $310，000 that the cloning would cost.The new dogs should look identical (完全相同的) to Wolfie and Bubble.When the cloning process is done，Onruang may end up with several clones of each dog.
14、But Onruang admits hes still not sure that they will be exactly the same.Scientists cloned the first animal，a sheep named Dolly，in 1996 in Scotland.That project has raised ethical (伦理的) questions about where science should draw the line.Another question is whether such technique will lead to a day w
15、hen humans could be cloned.“If I had an opportunity to clone myself，I would do it readily，” Onruang said.“Because its me，Im raising myself.I have already known exactly my strengths and weaknesses.This person is going to be the new and improved me，and will live the life Ive always wanted to live.”【语篇

18、 great benefit to humansC推理判断题。第四段主要讲的是关于克隆羊多莉出生后在社会上引发的关于克隆的一些争议，有人认为这关乎伦理问题。故选C。7What is Onruangs attitude towards cloning humans?AHe doesnt care about it.BHe is enthusiastic about it.CHe strongly opposes it.DHe never thinks about it.B推理判断题。根据最后一段“If I had an opportunity to clone myself，I would do
19、 it readily”可知，Onruang的观点是：如果他有机会克隆自己，那么他就会去做。故选B。CEvery student wants to learn English well，but how can we learn it well？Its a good topic for English learners.Here are some good methods，which can help you improve your English quickly.First of all，you must have correct attitude.Please love English，n

38、duce more milk or meat. 16 However, this practice is very controversial, and livestock farmers have been hesitant to adopt it fully because of public opposition and certain inefficiencies.In technical terms, livestock are cloned by taking cells from one animal and using them to fertilize eggs (使卵子受精
39、). Scientists take the fertilized eggs and put them in female animals. 17 Many animals are born with abnormal shapes.Scientists are looking for ways to improve the process and make it less expensive to adopt on a wider scale. 18 For example, if farmers were able to take only their very best animals
40、and recreate them many times, they could potentially be more productive.There are also some potential problems with cloned livestock. 19 For example, when a disease hits, there are usually individuals who cannot be harmed by the disease or are more resistant, and they will generally survive.If all t
41、he animals were genetically (在基因方面)identical or similar, this sort of disease could totally destroy an entire generation of livestock, leaving the world with a massive food shortage.In addition to concerns about genetic diversity, there are other concerns about cloning. 20 There are also some people

43、he potential to provide some major benefits.ECloning animals shows us what might happen if we try to clone humans.FThese concerns sometimes come from worries over unforeseen consequences.GThis process doesnt always work perfectly, and it can be relatively expensive.【语篇解读】本文是说明文。文章介绍了动物克隆技术。16B根据上一句内
44、容可知，如果能克隆出生产更多奶和肉的牛，那么“这个新品种应该是更好”。17G根据本空后的“Many animals are born with abnormal shapes.make it less expensive”可知，目前克隆的“过程不总是完美，而且价格相对来说比较昂贵”。18D根据本空后的内容不难看出，这里是介绍克隆牲畜的“好处”。19C根据本空后内容可知，克隆技术会减少“基因多样性”，所以当拥有同样基因的动物遭受某种致命疾病时，所有的这些动物都会死亡。下段首句中的“genetic diversity”也提示了本题答案。20F本空前的concerns提示了本题答案。.完形填空(共1
