Although some sketics points to Acrtic places such as the high latitudes of Greenland, where temperatures seem to have fallen, a recent scientific report concludes that in recent decade average temperature have increased faster in the Arctic than elsewhere. Scientists have long suspected that several factors lead to greater temperature swings at Earth's Polar Region than elsewhere. First, most of the Artic is coverd in snow and ice, which are highly reflective; if snow and ice melt, the exposed soil, which absorb hear, serve 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
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 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.
选项是B,我选了D。我的思路:既然 a recent scientific report指出了诸如土壤、雪这些人能导致气温变化大的因素,那么skeptics应该避开这些因素去捍卫他们的观点吧?不过,不确定我是否理解对了题目的意思,以及B的意思。。。求各位大大指点!
对于B和C选项,我觉得这里其实存在一个细节问题:
在第一段让步段的后一句写到:
a recent scientific report concludes that in recent decade average temperature have increased faster in the Arctic than elsewhere.
increased faster所以让步的内容应该重点在faster上,所以怀疑论者的问题不应该是气温下降,而是与全球趋势相反,也就是说,他们的观点可以是北极气温上升没那么快
所以C是正确的
