问题     Although some skeptics points to Arctic places such as the high latitudes of Greenland, where temperatures seem to have fallen, a recent scientific report concludes that in recent decades average temperatures have increased faster in the Arctic than elsewhere. Scientists have long suspected that several factors lead to greater temperature swings at Earth’s polar regions than elsewhere. First, most of the Arctic is covered in snow and ice, which are highly reflective; if snow and ice melt, the exposed soil, which absorbs heat, serves to accelerate warming. Second, the polar atmosphere is thin, so little energy is required to warm it. Third, less solar energy is lost in evaporation at the frigid poles than in the tropics.
In pointing to the apparent temperature change in the high latitudes of Greenland, the skeptics mentioned in the passage intend to raise as a question whether

选项 A、Greenland is less likely to experience extreme temperature changes than are other areas of the arctic.
B、those more localized temperature drops might indicate an important trend not captured by the upward trend of average arctic temperatures.
C、there might be a reversal of the temperature trend in the high latitudes of Greenland.
D、the factors that cause temperature change in the high latitudes of Greenland are different from those that affect the rest of the arctic.
E、Greenland has more ice and snow on the ground than do other areas of the arctic.

答案B

解析 本题相当于问“skeptics”的观点被提出的目的,定位到第一句的让步部分。由第一句可知,skeptics之所以提出格陵兰岛温度下降,是为了和后面的科学报告形成冲突。选项B的those more localized temperature drops对应skeptics观点中格陵兰岛的温度下降;upward trend of average arctic temperatures对应科学报告中的北极地区平均温度上升。将选项B和题干连起来翻译“在指出格陵兰岛高纬度地区的明显的温度变化时,文中提到的怀疑论者的目的是质问那些更局部的温度下降趋势是否并没有被两极平均温度的向上趋势捕捉到”。skeptics肯定不同意科学报告的观点,选项B正好可以表达出这种含义,因此选项B正确。A项文中没有讨论格陵兰岛是否会经历更极端的温度变化。C项skeptics和科学报告确实一个说温度下降一个说温度上升,但这只是两个不同观点的冲突,并不能说格陵兰岛的温度趋势有没有逆转。D、E项:根据skeptics的观点,格陵兰岛只是北极地区的例子,而这两个选项都认为格陵兰岛与北极其他地方不同。
