But the newborn kid died within minutes of birth due to breathing difficulties, signaling 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 pletely in 2021. Before the death of the last known individual (a 13 year old female known as Celia), biologists captured 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 ibex goat hybrid cloned embryos(胚胎 ). Of these cloned embryos,57 were transferred into 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 experiment 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 geically identical to the bucardo. In species such as bucardo, cloning is the only possibility to avoid its plete disappearance”． The failure to produce a 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 in 1936, and others hope that woolly mammoths preserved in permafrost could one day be 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 pygmy hippo. The method39。這 種野生山羊在 2021年就已經(jīng)滅絕了。根據(jù)第二段 the newborn cloned kid died after seven minutes as a result of lung ，這只克隆羊死于肺病。根據(jù)第三段 cloning is the only possibility to avoid its plete ， Jose Folch認為克隆有可能避免物種滅絕。根據(jù)最后一段 Supporters believe cloning provides hope of keeping these endangered animals alive before they die ，運用克隆技術(shù)來挽救瀕危動物是有希望的。s the best title for this passage? A． Great advancement in cloning goats B． Difficulties in saving extinct animals C． Public concerns about cloning D． Cloning brought back an extinct species for a while 解析 主旨大意題。 答案 D B We each have a unique geic(基因的，遺傳的 ) make up. Every cell of your body has the same set of about 100,000 separate genes made of 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 binations of DNA which e from the random mixing of your parents39。 40. What is the main idea of the first paragraph? A． We cannot easily change our physical appearance. B． How we turn out depends on our parents39。第一段主要介紹人的特殊性的兩個原因：一個是遺傳基因，一個是生活經(jīng)歷。根據(jù)第二段第一、二句可知，科學(xué)家正在研究雙胞胎，是為了弄清楚到底是遺傳基因還是生活經(jīng)歷在塑造人的外貌和性格上起著更重要的作用。根據(jù)第一段中的 “ Except for identical twins (同卵雙胞胎 )，no one has the same bination as another person.” 可知，同卵雙胞胎的基因是相同的。根據(jù)第三段中的 “But resistance to pain
