26、，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。AAn extinct mountain goat that was once common in the Pyrenees briefly became the first animal to be brought back from extinction, as researchers used frozen DNA to produce a clone. But the newborn kid died within minutes of birth due to breathing difficulties, signaling
27、 that the Jurassic Park dream of resurrecting extinct species is still some way off.The Pyrenean ibex, or bucardo, is a subspecies of the Spanish ibex that is believed to have died out completely in 2000. Before the death of the last known individual (a 13yearold female known as Celia), biologists c
28、aptured her and took cells from her skin and ears, which were frozen in liquid nitrogen(氮). An earlier cloning attempt using the skin cells failed during gestation. But the latest attempt involved the creation of 439 ibexgoat hybrid cloned embryos(胚胎). Of these cloned embryos,57 were transferred int
29、o surrogate mothers and seven resulted in pregnancies, but only one goat gave birth and the newborn clone died after seven minutes as a result of lung desease.Researchers say that other cloned animals, including sheep, have been born with similar lung defects, but they say that overall the experimen
30、t was a major step forward in the effort to bring the ibex back to its mountain home. Says lead researcher Jose Folch: “The delivered kid was genetically identical to the bucardo. In species such as bucardo, cloning is the only possibility to avoid its complete disappearance”The failure to produce a
31、 viable clone from DNA that was frozen only a decade ago illustrates the difficulty researchers would face in trying to bring back species that have been extinct for decades, centuries, millennia, or epochs. Researchers have floated the idea of bringing back the Tasmanian Tiger, which went extinct i
32、n 1936, and others hope that woolly mammoths preserved in permafrost could one day be resurrected.Those efforts are still largely hypothetical. There are, however, other serious proposals for cloning endangered animals, such as the giant panda, the African bongo antelope, the Sumatran tiger and the
33、pygmy hippo. The methods advocates believe it offers hope of preserving the genetic diversity of these animals before they die out.【语篇解读】 科学家通过冻结的DNA成功地克隆了一只比利牛斯野生山羊。这种野生山羊在2000年就已经灭绝了。36What do we know about the cloned ibex?AIt died of lung disease.BIt was the first cloned animal in the world.CIt l
34、ived for thirteen years.DIt was born in 2000.解析细节理解题。根据第二段the newborn cloned kid died after seven minutes as a result of lung disease.可知，这只克隆羊死于肺病。答案A37Jose Folch would agree that cloning_.Ais not suitable and should be bannedBrequires immediate attentionCshould be carried out cautiouslyDmay help pr

36、to preserve endangered speciesDcloning seldom results in physical problems for animals解析推理判断题。根据最后一段Supporters believe cloning provides hope of keeping these endangered animals alive before they die out.可以推断，运用克隆技术来挽救濒危动物是有希望的。答案C39Whats the best title for this passage?AGreat advancement in cloning
37、goatsBDifficulties in saving extinct animalsCPublic concerns about cloningDCloning brought back an extinct species for a while解析主旨大意题。通读全文，可知科学家们克隆了一只已经灭绝的比利牛斯野生山羊，但这只羊在出生不久就死了，故D项最适合作文章标题。答案DBWe each have a unique genetic(基因的，遗传的) makeup. Every cell of your body has the same set of about 100,000 se
38、parate genes made of DNA.These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion combinations of DNA which come from the random mixing of your parents genes. Except for identical twins(同卵双胞胎)
39、, no one has the same combination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make.But are genes or
40、 life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 birthssome are identical and others are nonidentical twins. Identical twins are special because they share exactly the same genes and often the sam
41、e environment. Nonidentical twins are more like ordinary brothers and sisters.Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inher
42、it. For example, we know that eye problems, like shortsightedness, are mostly genetic.But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amo
43、unt. Nonidentical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than nonidentical twins.Scientists are trying to identify the different genes that influence our behaviour. Some people are thril
44、lseekers and get into risktaking and adventurous activities.They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.We could ask，“Are our lives determined by our genes or our upbringing？” Scientists are learning more all the time,
45、 but it is certainly true that both are important in making us who we are.【语篇解读】 本文主要介绍基因和生活经历对人的外貌、性格等的形成所起的作用。 40. What is the main idea of the first paragraph?AWe cannot easily change our physical appearance.BHow we turn out depends on our parents genes.CEveryone has a physical double somewhere i
46、n the world.DBoth our genes and our experiences make us who we are.解析主旨大意题。第一段主要介绍人的特殊性的两个原因：一个是遗传基因，一个是生活经历。答案D41. Why are scientists studying twins?ATo find out how many twins are born every year.BTo discover what shapes us as individuals.CTo compare differences between twins.DTo study brotherands
47、ister relationships.解析细节理解题。根据第二段第一、二句可知，科学家正在研究双胞胎，是为了弄清楚到底是遗传基因还是生活经历在塑造人的外貌和性格上起着更重要的作用。答案B42. According to the passage，_.Aone in 70 twins are genetically identicalBnonidentical twins are usually not of the same sexCtwins separated at birth behave exactly the sameDidentical twins are genetically
48、the same解析细节理解题。根据第一段中的“Except for identical twins (同卵双胞胎)，no one has the same combination as another person.”可知，同卵双胞胎的基因是相同的。答案D43. Which of the following is most affected by experience according the passage?AEating habits. BEyesight.CPain resistance. DMarriage patterns.解析细节理解题。根据第三段中的“But resistan
49、ce to pain is largely dependent on experiences.”可知，应选C。答案CCHave you seen Jurassic Park? In this film, scientists use DNA kept for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and more dangerous than expected.Thats n
50、othing more than a fiction.But could we really clone endangered animals?To date, the most successful attempt to do so was the cloning of a gaur, a rare oxlike animal from southeast Asia.Scientists used a cow to bring the cloned baby gaur, named Noah. Two days after birth, however, Noah died from a c
51、ommon bacterial infection. Other endangered species that may be cloned include the African bongo antelope (邦戈羚羊), the Sumatran tiger, the cheetah (猎豹), and the giant panda.Next, could we really clone extinct animals?In theory? Yes. To do this, you need a wellkept source of DNA from the extinct anima
52、ls such as wool mammoth (毛象), Tasmanian tiger, or even dinosaur, and a closely related species, still living, which could serve as a surrogate_mother.In reality? Probably not. On the one hand, its not likely that extinct animals DNA could survive undamaged for such a long time. Cloning extinct anima
53、ls as wool mammoth, Tasmanian tiger, or dinosaur is much more difficult due to the lack of properly wellpreserved DNA.On the other hand, for example, a gaur can have a cow as a_surrogate_mother,_definitely not a monkey. But what about an extinct animals as unique as the panda? What species could pos
54、sibly serve as a surrogate mother?Cloning presents many exciting possibilities. However, even if extinct animals are brought back, they could not survive in todays world.Not only do most extinct animals have no habitat to love in, but the other plants and animals they depended on for food may also b
55、e gone as well.【语篇解读】 我们可以克隆濒临灭绝的动物吗？我们能克隆已经灭绝的动物吗？44It can be learned from the text that_.Athe gaur is an extinct speciesBthe gaur lives in Asia and is endangeredCscientists have cloned the African bongo antelopeDboth the cheetah and the giant panda live in Asia解析由 a rare oxlike animal from southea

57、 related species(和一种极其相近的物种 )，可知。其实通过文章意思也不难猜出它的意思。答案C46The difficulty in cloning an extinct species is the lack of_.Aboth the wellpreserved DNA and a surrogate motherBboth the habitat to live in and the wellpreserved DNACboth the wellpreserved DNA and plants to live onDboth the habitat to live in a
58、nd plants to live on解析由much more difficult due to the lack of properly wellpreserved DNA.(要更加困难，由于缺乏完好的妥善保存的DNA。)和 What species could possibly serve as a surrogate mother？(什么物种可以作为代孕母亲)可知。答案A47In the authors opinion, it is possible that_.Aall the extinct species may be clonedBextinct species may be
59、cloned and easily surviveCa gaur can have a monkey as a surrogate motherDsome extinct species may be cloned, but not survive解析由even if extinct animals were brought back, they could not survive in todays world.(即使灭绝的动物能够被克隆回来，他们也无法在现今的世界中存活)可知。答案DDThe United States government wants to know what the p
60、ublic thinks about its findings on the safety of cloned animals.The Food and Drug Administration says meat and milk from clones of adult cattle, pigs and goats are safe to eat. An FD.A.official called them “as safe to eat as the food we eat every day.” And when those clones reproduce sexually(有性繁殖),
61、 the agency says, their offspring(后代) are safe to eat as well. But research on cloned sheep is limited. So the FD.A.proposes that sheep clones not be used for human food.The United States this year could become the first country to approve the sale of foods from cloned animals. First, however, the p
62、ublic will have ninety days to comment on three proposed documents. On December 28th the FD.A.released a long report, called a draft risk assessment, along with two policy documents.The agency says it must receive comments by April second. The FD.A.seemed ready to act several years ago, but an advis
63、ory committee called for more research.For now, the government will continue to ask producers to honor a request that they not sell foods from cloned animals.Clones are still rare. They cost a lot and are difficult to produce.The FD.A.says most food from cloning is expected to come not from clones t
64、hemselves, but from their sexually reproduced offspring. It says clones are expected to be used mostly as breeding animals to spread good qualities.Public opinion studies show most Americans do not like the idea of food from cloned animals. But this research also shows the public knows little about
65、cloning.Cloning differs from genetic engineering. A cell taken from a socalled donor animals is grown into an embryo(胚胎)in the laboratory. Next, the embryo is placed into the uterus(子宫)of a female animal. If the process is successful, the pregnancy reaches full term and a genetic copy of the donor a

74、ges cant be met by any one leader or any one nation.And thats why my administration has worked to establish a new era of engagement in which all nations must take responsibility for the world we seek.We cannot tolerate a world in which nuclear weapons spread to more nations and in which the terror o
75、f a nuclear holocaust endangers more people.And thats why weve begun to take concrete steps to pursue a world without nuclear weapons，because all nations have the right to pursue peaceful nuclear power，but all nations have the responsibility to demonstrate their peaceful intentions.We cannot accept
76、the growing threat posed by climate change，which could forever damage the world that we pass on to our childrensowing conflict and famine；destroying coastlines and emptying cities.And thats why all nations must now accept their share of responsibility for transforming the way that we use energy.We c
