问题 Even the most uninformed student of climate change could tell you that the solution to global warming is to alleviate global greenhouse gas emissions, and fast. But the problem is that the sheer amount of greenhouse gases we’ve already pumped into the atmosphere has irreversibly bound us to a certain amount of warming over the next several decades. No matter what we do, we’ll have to adapt to it.　　(1)_______________. Already precipitation patterns seem to be changing, making some drier areas—like the arid American southwest —even drier, and rainy regions even wetter. As warmer temperatures creep northward, so do insects and other pests that are adapted to the heat. The results can be distressing. The tiny mountain pine beetle, which infests pine trees in the Rocky Mountain region, used to be controlled by freezing winters. But as temperatures have warmed over the past decade, the mountain pine beetle’s territory has spread, destroying millions of acres of Canadian pines.　　(2)_______________Generations of American conservationists have fought to preserve wild- life and to keep nature pristine in the face of a growing population and pollution. To a remarkable extent, they’ve succeeded—almost 16% of the entire landmass of the U.S. is protected, and the Endangered Species Acthas helped save countless animals from extinction.　　(3)_______________. What good is a wildlife reserve if the protected animals can’t live there, because climate change pushes them out? What difference does it make to defend trees from logging, if global warming will allow a new pest to destroy whole forests?　　(4)_______________. Last week the Lincoln Institute of Land Policy brought together conservation leaders from around the U.S. to discuss how to cope with warming, trying to work out a new framework for the biggest challenge facing conservation.　　(5)_______________. So too is the scale required to properly adapt to climate change, which will almost certainly continue for decades into the future. “Climate change will affect agriculture, water resources, forestry, transportation, waste management, energy generation, national security, immigration patterns, fisheries, food security, you name it,” said Lara Hansen. “We need to change the way we allocate resources, plan economies and protect livelihoods.”　　That means that the way we’ve been carrying out conservation—picking the right land spaces and playing goalie—won’t work anymore, as climate change keeps moving the target. Regardless of what we do, the changes will be coming fast. We need to begin cutting our carbon immediately, but we need to adapt now as well. The world is changing because of us; to save what’s left, we’ll have to change too.　　[A] But global warming threatens to change all that, by altering the very foundation on which the conservation movement was built.　　[B] Global warming was already having “profound effects” in the American West, and that the future would bring increased drought, heat waves, rainstorms, extinctions and more.　　[C] That means climate change isn’t a problem for tomorrow; the effects are happening now.　　[D] The conference was fruitful, if a bit depressing. What’s clear is that the sheer speed of the changes already taking place due to warming—like the mountain pine beetle infestation—are catching us off guard.　　[E] Conservationists will have to work even harder, trying to minimize non climate-related threats to land and species.　　[F] The pine beetle infestation is just one example of global warming’s present danger. It also represents the unique challenges that warming will pose for land conservation managers on the front lines of the battle against it.　　[G] The answer is to adapt the way we practice wildlife and land conservation to climate change. There’s a term for this—adaptive management.(此文选自Time2008年刊)
选项
答案
解析1. C　本文首段提出全球气候变暖已是事实，我们在今后不得不面对而且还必须适应此问题。空格后接着用Already一词引出当下气候的变化，并以山松甲虫为例对目前气候变化的影响进行了具体说明。C指出气候变化不仅会对未来产生影响，而且对当今世界也发生着影响，承上启下，因此C是正确答案。对此空干扰较大的是B 选项，B主要讲气候变暖已对美国西部产生了深刻影响，且在将来会引发更多的不良现象。而下文主要讲目前状况，所以排除此选项。2. F　上段已详细讲述了山松甲虫的的事例。空格下文对土地保护管理者一直以来的努力进行了说明。F中的The pine beetle … danger.是续讲上文山松甲虫的事例，同时指出气候变暖对土地保护管理者来说是独特挑战，符合文章逻辑，故F为正确答案。3. A　上文介绍了自然资源保护管理人员所做的努力和取得的成效，A中的but语锋一转，指出虽然conservationists取得了很大成功，但是随着全球气候不断变暖，他们的所有努力都可能白费，开始持怀疑态度。作者在空格后提出的一系列问题 “What good… forests?”更进一步表明了自己的疑虑。 A表示转折意义符合上下文语境。此处E选项干扰较大，E项讲“资源保护者… …力图降低与气候无关的对土地和物种的威胁。”文中讲气候变暖对conservationists提出的巨大挑战，但未提及non climate-related threats，且与下文诸多问题缺少联系，不合文意，故排除。4. G　上文中作者提到气候变暖所产生的影响，并提出一系列问题。G中的The answer is…正是回答上文的问题，故为正确答案。5. D　上文段末提到资源保护领导人召开了会议，D中的“The conference....”承接上文，同时也提到了气候变暖的速度，又很好地引出下文 “So too is the scale…”，及后文气候变化对人们生活个方面的影响。故D符合语境。
