问题     Climate change and habitat loss are two huge threats to animal and plant survival, but a new study shows how managing both factors could help prevent extinctions. Cutting greenhouse gas【B1】 ________  and protecting more tropical land could 【B2】 ________  the probability of species blinking out, called extinction risk, by more than half, the research found.
    Scientists had not previously calculated the【B3】 ________  benefits that limiting climate change and saving swaths of land could have【B4】 ________  so many species, says co-author Patrick Roehrdanz, a researcher with the nonprofit organization Conservation International.
    Climate change【B5】 ________  continue altering existing habitats, forcing more organisms to relocate or【B6】 ________  . For this study, published in February in Ecography, the researchers looked at existing and future habitat ranges for 104,059 plants and animals in South America, Africa and Asia and existing ranges for 185,160 more—the largest-ever【B7】 ________  of such data. They then modeled future extinction risk for those species【B8】 ________  certain percentages of the planet’s tropical land were placed【B9】 ________  protection (around 17 percent is protected now).
    The scientists calculated that with 30 percent protected, if greenhouse gases were also curtailed—【B10】 ________  the aim of keeping global temperature rise below two degrees Celsius above preindustrial【B11】 ________  —the species’ extinction risk could fall 【B12】 ________  more than 50 percent.
    These results could help inform United Nations officials【B13】 ________  to meet this year. Focused on conserving the world’s flora and fauna, the U. N. Convention on Biological Diversity has【B14】 ________ conserving 30 percent of Earth’s land and oceans by 2030. Formal protection from development could save【B15】 ________  ecosystems and mitigate the effects of climate change.
    The model does not, however,【B16】 ________  how different species interact with one another and with the landscape. A hummingbird may move to a new location, but the plants it【B17】 ________  may not, for example.【B18】 ________  , says Rachael Gallagher, a biologist at Australia’s Macquarie University in New South Wales,【B19】 ________  was not involved in the study, the paper "provides an evidence base for those advocating to【B20】 ________  the world’s protected areas.
【B10】
选项 A、consistent with
B、different from
C、compatible with
D、distinguished from
答案A
解析 逻辑关系题。选项的意思分别为[A]“与……一致”；[B]“与……不同”； [C]“与……兼容”；[D]“与……加以区别”。空格处前面提到“如果30％的土地受到保护，同时温室气体排放也相应减少”，后面提到“使全球气温较工业化时期前的升幅控制在低于2℃的水平”的目标。从逻辑关系上来说，科学家们希望通过保护土地和减少温室气体排放两项举措所达到的效果应该正是为了与此前设立的目标保持一致，因此答案选[A]。
