阅读材料,完成下列要求。2020年初新冠肺炎疫情,是新中国成立以来在我国发生的传播速度最快、感染范围最广、防控难度最大的一次重大突发公共卫生事件。材料一:疫情发生后,华夏儿女万众一心,共克时艰。各级党组织和广大党员、干部冲锋在前、顽强拼搏,广大医务工作者义无反顾、日夜奋战,人民解放军指战员闻令而动、敢打硬仗,广大人民群众众志成城、守望相助,广大公安民警、疾控工作人员、社区工作人员等坚守岗位、日夜值守,An extinct mountain goat that was once common in the Pyrenees became the first animal to be brought back from extinction. Researchers used frozen DNA to produce a clone, but the newborn kid died within minutes of birth due to breathing difficulties.The Pyrenean ibex is a type of mountain goat,which is believed to have died out completely in 2000. Before the death of the last known individual(a13-year-old female known as Celia), biologists took cells from her skin and ears. An earlier cloning attempt to use the skin cells failed. But the latest attempt involved the creation of 439 cloned embryos. Of these cloned embryos, 57 were put into the female domestic goats, but only one goat gave birth and the newborn cloned kid died after seven minutes as a result of lung disease.Researchers say that other cloned animals, including sheep, have been born with similar lung disease, but they say that overall the experiment was a major step forward in the effort to bring the ibex back to its mountain home. The leading researcher Jose Folch says, “the cloned kid was genetically like the ibex;in species such as the ibex,cloning is the only possibility to avoid its complete disappearance.”The failure to produce a living clone from DNA that was frozen only a decade ago shows the difficulty researchers would face in trying to bring back species that have been extinct(灭绝的) for decades or centuries. Researchers have had the idea of bringing back the Tasmanian tiger, which went extinct in 1936. There are, however, other species that have been seriously suggested for cloning,such as the giant panda, the African bongo antelope, the Sumatran tiger and the pygmy hippo. Supporters believe cloning provides hope of keeping these endangered animals alive before they die out.1.What do we know about the cloned ibex?A. It died of lung disease.B. It was the first cloned animal in the world.C. It lived for thirteen years.D. It was born in 2000.2.Jose Foleh would agree that cloning .A. is not suitable and should be banned.B. requires immediate attention.C. should be carried out cautiously.D. may help prevent animal extinction.3.We can conclude from the passage that .A. cloning has developed quickly in developed countries.B. no more animals will die out in the future.C. cloning makes it possible to preserve endangered species.D. cloning seldom results in physical problems for animals.4.What’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.
