5、ack of genetic diversity. this is one reason why fewer than half of kakapo eggs hatch. by sequencing the genome (测定基因组序列) of every living bird, scientists can identify closely­related individuals and put them on different islands. every bird is fitted with something to record its slightest move

6、ment. if a female mates with an “unsuitable” male, the process can be stopped. all these efforts cost new zealand almost $1.3 million this breeding season. yet the kakapo's future still looks unsafe. earlier this year a severe disease spread through the population. and tiny as the number of kaka

25、考查推理判断。根据第一段最后一句“when it moves unsteadily across something that might kill it，it will stand still”可知，当它摇摇晃晃地穿过可能会杀死它的东西时，它会静止不动。再结合第二段第一句可推知，当鸮面鹦鹉面对危险时，它不能做出积极的反应，这对鸮面鹦鹉的生存来说是一种威胁。故选d。2答案与解析：a'考查细节理解。根据第三段中的“the scientists' patience was finally rewarded. the rimu tree was in fruit this year,

26、 and more than 80 baby kakapos were born, making this the best breeding season on record”可知，科学家的耐心终于得到了回报。80多只雏鸟破壳而出，这是有记录以来最好的繁殖季节。故选a。3答案与解析： a'考查细节理解。根据第四段的内容可知，鸮面鹦鹉面临的另一个威胁是缺乏遗传多样性。通过测定每只活鸟的基因组序列，科学家可以识别出亲缘关系很近的个体，并把它们放在不同的岛屿上。由此可知，科学家们把鸮面鹦鹉放在不同的岛屿上，是为了阻止鸮面鹦鹉近亲交配。故选a。4答案与解析：d'考查推理判断。根据最后

27、一段的内容可知，然而，鸮面鹦鹉的未来看起来仍然不安全。今年早些时候，一种严重的疾病在鸟群中肆虐。尽管鸮面鹦鹉的数量很少，但它们生活的这两个岛屿上的空间已经所剩无几。由此可推知，作者认为保护新西兰鸮面鹦鹉的努力是不够的。故选d。b【语篇解读】本文是一篇说明文。文章介绍了飓风给人们带来的危害，同时给读者就如何应对突如其来的飓风提供了一些建议。5答案与解析：c'细节理解题。根据第二段中的“while most atlantic hurricanes form off the coast of africa giving plenty of early warning”可知大部分的大西洋飓风是

28、在非洲海岸形成的，所以选c。6答案与解析：b'主旨大意题。根据第三段中的关键词：oil workers, field archeologists, a texas national guard group和travelers可知，这段主要讲的是被飓风困住的人。所以选b。7答案与解析：a'推理判断题。根据最后一段中的“but there're a few things you can do to prepare yourself for some unexpected emergencies.”可知，这段主要介绍了一些建议怎样为预料之外的紧急情况做准备。所以选a。8答案与

29、解析：c'推理判断题。文章介绍了飓风给人们带来的危害，同时给读者提供了一些关于如何应对突如其来的飓风的建议。所以是和人们的生活密切相关的文章，所以选c。.完形填空【语篇解读】本文是一篇记叙文，讲述了作者与女儿发生了争执，然后向妻子请教解决办法的故事。1答案与解析：b'根据上文中的“i walked into my daughter's room as she was working on a science project”可知，此处指通常作者会很高兴看到女儿进行科学项目的情景。故选b项。2答案与解析：a'根据语境可知此处指沙子铺满新地板。下文中的“the sand is getting all over”是信息提示。此处spread
