Recording Two

W: Earlier this year, British explorer Pen Huddle and his team trekked for three months across the frozen Arctic Ocean, taking measurements and recording observations about the ice.
M: Well, we'd been led to believe that we would encounter a good proportion of this older, thicker, technically multi-year ice that's been around for a few years and just gets thicker and thicker. We actually found there wasn't any multi-year ice at all.
W: Satellite observations and submarine surveys over the past few years had shown less ice in the polar region, but the recent measurements show the loss is more pronounced than previously thought.
M: We're looking at roughly 80 percent loss of ice cover on the Arctic Ocean in 10 years, roughly 10 years, and 100 percent loss in nearly 20 years.
W: Cambridge scientist Peter Wadhams, who's been measuring and monitoring the Arctic since 1971 says the decline is irreversible.
M: The more you lose, the more open water is created, the more warming goes on in that open water during the summer, the less ice forms in winter, the more melt there is the following summer. It becomes a breakdown process where everything ends up accelerating until it's all gone.
W: Martin Sommerkorn runs the Arctic program for the environmental charity the World Wildlife Fund.
M: The Arctic sea ice holds a central position in the Earth's climate system and it's deteriorating faster than expected. Actually it has to translate into more urgency to deal with the climate change problem and reduce emissions.
W: Summerkorn says a plan to reduce greenhouse gas emissions blamed for global warming needs to come out of the Copenhagen Climate Change Summit in December.
M: We have to basically achieve there the commitment to deal with the problem now. That's the minimum. We have to do that equitably and we have to find a commitment that is quick.
W: Wadhams echoes the need for urgency.
M: The carbon that we've put into the atmosphere keeps having a warming effect for 100 years. So we have to cut back rapidly now, because it will take a long time to work its way through into a response by the atmosphere. We can't switch off global warming just by being good in the future, we have to start being good now.
W: Wadhams says there is no easy technological fix to climate change. He and other scientists say there are basically two options to replacing fossil fuels, generating energy with renewables, or embracing nuclear power.

Q19：What did Pen Huddle and his team do in the Arctic Ocean?

本题问佩恩·哈多和他的团队在北冰洋做的事情。对话开头就提到:“今年早些时候，英国探险家佩恩·哈多和他的团队在冰封的北冰洋上长途跋涉了三个月，对冰进行测量并记录观测数据。”故选D。其他三项录音中均未提及，故排除。

Q20：What does the report say about the Arctic region?

录音前半部分指出，最近的测量数据显示，极地地区冰数量的减少比人们之前想象的更加显著。D项中的decrease和evident分别对应原文中的lost和pronounced，故为正确答案。录音中提到，研究团队认为，在未来的大概十年间，北冰洋的冰层将减少大约80%，而不是说80%的冰在夏季消失，故排除A。选项B和C在录音中没有提及。

Q21：What does Cambridge scientist Peter Waddams say in his study?

录音中间部分指出，剑桥的科学家彼得·沃德姆斯认为北极冰的减少是不可逆转的，故选C。其他三项在录音中均无法找到根据。

Q22：How does Peter Waddams view climate change?

在录音的最后，沃德姆斯表示，并没有简单的技术补救措施来应对气候变化。这与选项D的说法一致，选项D中的technological solution对应录音中的technological fix。A项属于过度推断；B项在录音中并未提及；根据沃德姆斯所言，使用核能将是解决气候问题的方法之一，但气候变化能否推动核技术的发展不得而知，故C项也不正确。
