老烤鸭雅思原创解析,请勿抄袭或转载
第14题答案:F
对应原文:F段:how we could use it to make genetic modifications which could prevent mass extinctions in the future.
答案解析:F段中后部提到,“我们如何利用这一技术进行基因修饰,以阻止未来的大规模灭绝”。其中future对应further,mass extinctions对应disappearance,prevent对应avoid,由此确定答案。
第15题答案:A
对应原文:A段:The basic premise involves using cloning technology to turn the DNA of extinct animals into a fertilised embryo, which is carried by the nearest relative still in existence … before being born as a living, breathing animal.
答案解析:A段提及复活灭绝动物的具体方法:“利用克隆技术将已灭绝动物的DNA植入到受精胚胎中。然后有现存的亲缘最近的物种孕育出活生生的、会呼吸的动物”,由此确定答案。
第16题答案:D
对应原文:D段:Since the disappearance of this key species, ecosystems in the eastern US have suffered
答案解析:D段中部提到,“自从这一关键物种小时以来,美国东部的生态系统饱受其苦”。随后又具体解释了候鸽的消失对森林以及生活在其中的物种的影响,由此确定答案。
第17题答案:A
对应原文:A段:the passenger pigeon’s existence came to an end on 1 September 1914
答案解析:原文中只有A段提到候鸽的准确灭绝时间,即1914年9月1日,对应题干中的exact point,由此确定答案。
第18题答案:genetic traits
对应原文:E段:By pinpointing which genetic traits made it possible for mammoths to survive the icy climate of the tundra
答案解析:根据woolly mamoth和George Church定位到E段,再根据tundra定位到这句话,identify与pinpointing同义替换,由此确定答案为gennetic traits。需要注意的是,在题目要求文章来自老烤鸭雅思为不超过两个单词的情况下,一定要将名词前面的修饰词带上。
第19题答案:heat loss
对应原文:E段:Necessary adaptations would include smaller ears, thicker hair, and extra insulating fat, all for the purpose of reducing heat loss in the tundra
答案解析:根据adaptations定位到这句话,空前词minimise与reducing同义替换,由此确定答案为heat loss。
第20题答案:ears
对应原文:E段:Necessary adaptations would include smaller ears, thicker hair, and extra insulating fat
答案解析:这道题的答案出现在上一道题的前面,不过根据hair很容易找到相应内容,由并列关系以及reduced size与smaller的对应,确定答案为ears。
第21题答案:(insulating) fat
对应原文:同上
答案解析:more与extra对应,由此确定答案为insulating fat。
第22题答案:(carbon) emissions
对应原文:E段:This grass growth would reduce temperatures, and mitigate emissions from melting permafrost.
答案解析:根据teperatures定位到这句话,空前词decrease与mitigate同义替换,由此确定答案为emissions。
第23题答案:B
对应原文:B段:Michael Archer … ‘The return of thylacines to Tasmania could help to ensure that devils are never again subjected to risks of this kind.’
答案解析:B段提到,“塔斯马尼亚岛上袋狼的回归有助于确保袋獾永远不再遭受此类威胁”。risks即指代上文中的疾病。其中thylacines对应extinct species,Tasmania对应orginal habitat,health对应疾病,devils对应particular species,由此确定B选项Michael Archer为答案。
第24题答案:C
对应原文:F段:… Shapiro. She prefers to focus the debate on how this emerging technology could be used to fully understand why various species went extinct in the first place
答案解析:F段中提到,“Shapiro更倾向于关注如下争论:如何利用这一新兴技术来全面了解当初各类物种为什么会灭绝”。由此确定答案为C。
第25题答案:A
对应原文:D段:… in theory, re-establish that forest disturbance, thereby creating a habitat necessary for a great many other native species to thrive.
答案解析:除了D段Novak之外,E段中George Church也提到植物的问题。但他说的是大象可以让草皮生长,并没有提到habitat的事情,由此排除E,确定A选项Novak为正确答案。
第26题答案:C
对应原文:F段:Shapiro … We know that what we are doing today is not enough
答案解析:F段最后提到,“我们知道我们如今做的并不够”。其中not enough对应insufficient,而what we are doing由上下文可以对应preserving biodiversity,由此确定答案为C选项Beth Shapiro。
