单选题
The purpose of this passage is to ______.
A
frighten people with the rapid melting of the Greenland ice sheet
B
urge people to take some measures to curb the melting of the Greenland ice sheet
C
promote people’s environmental protection consciousness
D
let people know the time the Greenland ice sheet will take to melt
参考答案和解析
正确答案：
D
解析：
该段录音首先指出IPCC认为至少等1000年格陵兰岛冰盖才会融化，但是Lenton’s group表示300年内该冰盖就会断裂，那时亿万人将会受到影响，从录音最后Lenton提到的“格陵兰岛冰盖断裂很快就会变得无法避免，但是我们并不认为我们已经度过了临界点”，可见该段录音主要是想提高人们的环保意识。
【录音原文】
The IPCC says the Greenland ice sheet will take at least l, 000 years to melt. But Lenton’s group—whose members include John Schellnhuber, the chief scientist on climate change at the recent G8 meeting in Germany—says the sheet could break up within 300 years, raising sea levels by 7 meters. This would flood hundreds of millions of people or more out of their homes. “We are close to being committed to a collapse of the Greenland ice sheet,” Lenton says. “But we don’t think we have passed the tipping point yet.”

Climate Change:The Long Reach
1.Earth is warming.Sea levels are rising.There's more carbon in the air,and Arctic ice is melting faster than at any time in recorded history.Scientists who study the environment to better gauge（评估） Earth's future climate now argue that these changes may not reverse for a very long time.
2.People burn fossil fuels like coal and oil for energy.That burning releases carbon dioxide,a colorless gas.In the air,this gas traps heat at Earth's surface.And the more carbon dioxide released,the more the planet warms.If current consumption of fossil fuels doesn't slow,the long-term climate impacts could last thousands of years-and be more severe than scientists had been expecting.Climatologist Richard
Zeebe of the University of Hawaii at Manoa offers this conclusion in a new paper.
3.Most climate-change studies look at what's going to happen in the next century or so.During that time, changes in the planet' s environment could nudge（推动）global warming even higher.For example, snow and ice reflect sunlight back into space.But as these melt,sunlight can now reach-and warm-the exposed ground.This extra heat raises the air temperature even more,causing even more snow to melt.This type of rapid exaggeration of impacts is called a"fast feedback".
4.Zeebe says it's important to look at fast feedbacks.However,he adds,they're limited.From a climate change perspective,"This century is the most important time for the next few generations,"he told Science News."But the world is not ending in 2100."For this new study,Zeebe now focuses on"slow feedbacks".While fast feedback events unfold over decades or centuries,slow feedbacks can take thousands of years.Melting of continental ice sheets and the migration of plant life-as they relocate to more comfortable areas-are two examples of slow feedbacks.
5.Zeebe gathered information from previously published studies investigating how such processes played out over thousands of years during past dramatic changes in climate.Then he came up with a forecast for the future that accounts for both slow and fast feedback processes.Climate forecasts that use only fast feedbacks predict a 4.5 degree Celsius(8.1 degree Fahrenheit)change by the year 3000.But slow feedbacks added another 1.5℃-for a 6℃ total increase,Zeebe reports.He also found that slow feedback events will cause global warming to persist for thousands of years after people run out of fossil fuels to burn.

答案：A
解析：
第二段第一句就说人们燃烧化石燃料，随后又指出这样会释放二氧化碳，紧接着就说二氧化碳的危害。由此可知，第二段主要讲的是燃烧化石燃料的危害。
第三段主要讲的是，冰雪融化导致地表裸露，然后太阳可以直射地表，使地表升温，反过来又促使冰雪融化。这些都是对“快速反馈”的解释，即认为燃烧化石燃料会使温室效应愈演愈烈。
第四段主要表明，化石燃料燃烧的危害将长期存在，不会在短时间内得到根治，即便过了本世纪，其危害将会依然存在。这些是对“缓慢反馈”的解释，冰山融化与植物迁徙是“缓慢反馈”的两个例子。
第五段的第二句是主题句，主要讲的是Zeebe在考虑了“快速反馈”和“缓慢反馈”的同时，对未来气候变化做的一种预测。
根据第一段第三句“…recorded history.”可知，空格处应填D项。
根据第三段第四句“…exposed ground.”可知，空格处应填A项。
根据第五段第一句“.previously published studies...”可知，空格处应填E项。
根据文章最后一句“…thousands of years...”可知，空格处应填B项。"a very long time" 是对“thousands of years”的同义转换。

第9题：
资料：A high-precision NASA radar instrument left a NASA airport in Southern California for Iceland on January 28 to create detailed maps of how glaciers move in the dead of winter. This will help scientists around the world better understand some of the most basic processes involved in melting glaciers, which are major contributors to rising sea levels.
NASA used the same airborne instrument in June 2012 to map the summer flows of two Icelandic ice caps. The ice caps — large areas of permanent snow and ice cover — encompass multiple glaciers flowing in different directions and at different speeds. By mapping the same ice caps now, in winter, when the surface remains frozen all day, and then comparing the winter and summer velocities, the researchers will be able to isolate the effects of melt water.
Above is a view of a small part of the Hofsjkull ice cap, which encompasses several glaciers. The fan at upper left is part of a glacier called Mlaj?kull.
For more on the research, see this NASA press release.
How can the scientists figure out the effects of melting water?
