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.
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 (a 13-year-old female known as Celia), biologists took cells from her skin and ears, which were frozen in liquid nitrogen (氮)．An earlier cloning attempt to use the skin cells failed.But the latest attempt involved the creation of 439 cloned embryos (胚胎)．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 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.
[语篇解读] 这篇文章通过记叙克隆羊失败来说明克隆技术可以帮助避免
珍稀动物的灭绝，但是目前还是困难重重。
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.
解析：细节理解题。根据第二段中的“...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：A
2．Jose Folch 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 extinctions
解析：细节理解题。根据第三段最后一句中的“...cloning is the only possibility to avoid its complete disappearance.”可知，Jose Folch认为克隆有可能避免物种灭绝。
答案：D
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
解析：推理判断题。根据最后一段最后一句“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：C
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
解析：标题归纳题。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：D Ⅴ.完形填空
When it comes to cloning, it is always controversial.While it is agreed that this technology is not 1 ， it still has some benefits.
Human cloning technology could be used to cure heart attacks.Scientists believe that they may be able to 2 heart attacks by cloning their healthy heart cells and 3 them into the areas of the heart that have been damaged, and other problems may be solved if human cloning and its technology are not 4 . By 5 cloning, infertile (不育的) couples could have children. 6 treatments for infertility, in terms of percentages, are not very 7 .Couples go through physically and emotionally painful 8 for a small chance of having children.Many couples 9 time and money without successfully having children.Human cloning could make it 10 for more infertile couples to have children than ever before.
We can be able to 11 the bone marrow (骨髓) for children and adults 12 leukemia (白血病)．This is expected to be one of the first 13 to come from cloning technology.We may learn how to 14 cell functions on and off through cloning and 15 be able to cure cancer.
Cloning technology can be used to 16 and perhaps cure gene-related 17 .The above is just a few 18 of what human cloning technology can do for mankind.This new technology will 19 further advancement in medicine if people get over their 20 and let the benefit begin.
