问题    The impacts of climate change are real. Plant and animal habitats are changing, glaciers are melting and heat waves and floods are becoming more frequent. All this causes me to question the utility of my work as an environmental scientist.
   Environmental scientists are calling attention to changes in the natural world that are driven by carbon emissions from burning fossil fuels. In doing so, we speak of the " grief" of climate science, using words such as " demoralizing" , " conflicted" and " deep sense of worry". We have a responsibility to lead change. This responsibility raises questions, such as: how do scientists cope with the emotional burden of their knowledge? And how can these emotions galvanize (激励) us into action?
   In 2017, I joined Homeward Bound, a global environmental-leadership programme for women in science that launched in 2016. Each year, the programme coaches up to 150 women for 12 months, culminating in a 3-week voyage to Antarctica, where female scientists develop their confidence and strategic vision for acting together on climate change. The programme has focused my attention on projecting my voice as an environmental scientist.
   In 2015, I became a councillor of the Australian Coral Reef Society (ACRS), the world’s oldest society for protecting Australia’s coral reefs, which has a track record of calling for change. That year, we wrote submissions and reports on behalf of more than 300 concerned scientists in what became known as the "coal versus coral" war. The Great Barrier Reef Marine Park Authority had approved a proposal to dump 3 million cubic metres of dredged sediment (疏浚底泥) from Abbot Point, a huge coal port in northern Queensland, into the Great Barrier Reef World Heritage Area.
   This would have been an environmental disaster, with plumes (羽状物) of sediment compromising marine life. The authority reversed its decision when the ACRS made its views known alongside those of conservationists, tourism operators, grassroots organizations such as GetUp! and the native climate group Seed. It was immensely satisfying to be part of this endeavour. To keep up the pressure, we sent a letter last August on behalf of the ACRS to Australia’s prime minister, Malcolm Turnbull, urging immediate action to curb carbon emissions.
   I have also begun to explore how interdisciplinary approaches weave together different practices to create powerful ways of communicating the science of climate change. Last September, I became an unlikely "artist in residence" at the Bundanon Trust in Illaroo, Australia, which supports creative work that emphasizes the value of landscapes. I am working with artists and a social scientist to untangle how interdisciplinary approaches saved the Great Barrier Reef from mining in the 1960s—and whether such approaches can help scientists to save it again.
   Emotional conflicts around climate change have prompted me to revisit the reasons I became an environmental scientist. I am now using forms of expression that resonate with my personal values and add scientific authority to the argument for resisting the coal industry. How will you lead the change you want to see?
Which of the following is closest in meaning to the word "untangle" (Line 4, Para. 6) ?
选项 A、Focus on.
B、Figure out.
C、Make sure.
D、Debate about.
答案B
解析 语义理解题。本题考查生词在文中的含义。第六段最后一句提到，作者和艺术家们及一个社会科学家共同工作，untangle之后是how和whether引导的两个并列的宾语从句，tangle意为“纠缠，处于混乱状态”，词缀un-可表示相反的动作，由此可知untangle应表示“弄清楚，理清”之意，同时也与其后宾语从句的意义相匹配，故答案为B)。A)“关注”和C)“确保”与其后疑问词引导的宾语从句不匹配，故排除；D)“就……辩论”，原文并没有提到作者与这些艺术家和科学家进行辩论，故排除。
